.To all whom it may concern: l

Be it known that I, JOHN HAYES, a citizen of the United States of America, residing in the city and county of Denver and State of Colorado,have inventedcertain new and useful Improvements in Sparring-lllachines; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part ofthis specification.

My invention relates to apparatus for physical training, and particularly `to an improved boxing-machine.

The objects of the invention are, first, to provide a suspended platform which is capable of a variety of horizontal movements and which carries a pair of blow-delivering' arms and a dummy for receiving blows, the said arms and platform being operated by a suitable fluid under pressure which is delivered to the machine from a storage-tank, said fluid being controlled by suitable valves which are operated by a toothed drum in such a manner as to permit the fluid to act upon an operating piston or pistons at a predetermined time and to exhaust from said piston or pistons at a predetermined time, said valves and drum also being carried by the suspended platform; second, to provide a machine of the character specified comprising a light suspended platform which is capable of a variety of horizontal movements and which carries a blowreceiving dummy and a pair of striking-arms which are adapted to deliver blows in a'variety of directions and from different vertical positions, said arms and platform being operated,

preferably, by compressed air, which is conveyed to operating-cylinders having pistons which effect the aforesaid movements of the arms and platform at predetermined periods, the entrance and exhaust of the air being controlled by suitable valves, which are operated by a toothed drum, the teeth of which may be arranged in such a manner as to operate a number ofvalves simultaneously or in rapid succession, so as to deliver the compressed air to a series of the operating-cylinders and thus effect a combination of movements of the platform and blows from the arms, the said combination of movements and blows being varied as the drum revolves; third, to provide a suspended counterbalanced platform carrying a blow-receiving dummy and a pair of strilingarms, said platform being arranged to counterfeit the backward, forward, and circling movement of a person while boxing, the arms at the same time being arranged to deliver horizontal blows or under and upper cut blows or inward and outward swinging blows, the movements of the platform and arms being similar to those employed in boxing, thus enabling the person exercising with the said machine to acquire the art of delivering and avoiding blows as well as of stepping backward or from side to side to avoid the forward or the swinging movement of the machine, the said movements and blows being effected, preferably, by compressed air, which may be so controlled as to regulate the force of the blows delivered by the arms as well as the rapidity of the movement of the platform.

With these and other objects in view the invention consists in the novel arrangements and construction of parts hereinafter described, and illustrated in the accompanying drawings, it being understood that various modifications in the form and details of the machine may be employed without departing' from the spirit of the invention.

In the accompanying' drawings, Figure l is a side elevation, partly in section, of the improved sparring-machine, the same being supported upon a horizontal' track which is pivoted to a suitable supporting structure. Fig. 2 is a front elevation of the machine. Fig. 3 is a plan view thereof, the horizontal member of the supporting' structure being omitted. Fig. 4 is a side elevation, partly in section, of one of the striking-arms and parts connected therewith, showing the spring by which the arm proper is returned to its normal position after delivering a blow. Fig. 5 is a front elevation, partly in section, of one of the rotatable supports for one of the striking-arms and for a cylinder having a piston and rod, which rod carries the said strikingarms. Fig. 6 is a side elevation of the rotatable support shown in Fig. 5.

showing teeth of different height secured one end of an air-supply pipe 3D is screwed,

thereto. Fig. 11 is a side elevation of a head and body blow receiving-dummy which can be used in place of the dummy shown in Figs. 1 and 2. Fig. 12 is a vertical sectional view showing the manner in which the machine is pivotally suspended from the supporting structure and the arrangement of ball-bearings which enable the machine to be quickly and easily turned. Fig. 13 is a plan view showing a portion of the rear end of the platform of the machine and illustrating another manner of turning the machine. Fig. 14 is a vertical longitudinal sectional view through one of a pair of cylinders which are employed to effect the forward and backward and swinging movements of the machine, and Fig. 15 is a sectional View, slightly reduced, of one of the air-exhaust valves.

Referring to the accompanying drawings, the numeral 1 indicates an upright, to which is secured a horizontal arm 2, and this upright and arm constitute the supporting structure for my im proved sparring-machine, said structure being strongly braced, so as to withstand vertical and lateral strain, due to the weight and variable movements of the machine. The upper face of the forward end of the arm 2 is provided with a suitable ball-race 3, and

upon the balls in said race rests the flanged end of a pipe 4, which extends through the arm 2 and a suitable distance below the same, and to the under side of the arm 2 is secured a plate 5, having a central opening through which the pipe 4 passes and around which a ball-race 6 is formed, having balls which receive the lateral thrust of the pipe. A plate 7 of greater diameter than the plate 5 is secured to the pipe in proximity to the plate 5. This plate is provided with a ball-race 8, having balls which bear against the under side of the plate 5 and is formed with a hub 9, through which a set-screw 1() passes and engages the pipe 4, thus securing' the plate to the pipe. Pins 11 project from the upper side of the plate 7, the object of which will hereinafter appear. The pipe 4 forms a pivotal support for the entire machine, and the bearings above described will permit the pipe to turn freely, as the amount of friction is thereby reduced to a minimum. The lower end of the pipe 4 is threaded, and a cross 12 is screwed thereon. This cross supports a horizontal bar or track 13, which passes through the horizontal member of the cross and which is provided with a vertical aperture 14, which registers with the bore of the pipe. This track is secured within the cross by set-screws 15. The ball-race 3 at the upper end of the pipe 4 is covered by a plate 3A, having an interiorly-threaded hub 3B, into which is screwed a nipple 3C, the l'ower end of which is smooth and extends a short distance into the upper end of the pipe 4. This nipple is provided with an elbow into which the other end of which connects with a storage-tank 3E.

The track 13 carries at its forward end a counterbalancing-weight 16, and from its rear end is suspended a frame or platform 17, which carries the operating mechanism of the improved sparring-machine. The platform is provided with uprights 18, which are connected by a horizontal member 19 at their upper ends. The member 19 is provided with rollers 20, which ride upon the track 13, and thus allow the machine to be moved back and forth, the platform 17 being positioned a Slight distance above the floor. The mechanism for moving the platform back and forth for revolving the same and for operating the counterbalancing-weight will be hereinafter fully set forth.

The platform 17 comprises a metal frame having thin metal cross-bars at points where it is desired to secure the several parts of the machine, as well as the brace-rods, the object being to have the platform as light and at the same time as strong' as possible. lThe forward end of the platform is reduced in width, as clearly shown in Fig. 3, and around this reduced end is secured a rubber tube 2l,which is preferably inflated with air to form a cushion which will prevent injury to the ankles of the person exercising with the said machine. Upon the forward end of the platform is a post or upright 22, which is braced by rods 23 and which preferably consists of a piece of light tubing which is firmly secured to the platform at its lower end, while its upper end carries either a stuffed or an inflated bead 24, as may best meet the requirements, and this head constitutes a dummy which receives the blows of the person exercising. At a suitable distance in rear of the dummy is secured a rectangular metal frame 25, which is of the same width as the platform and about as high as the shoulders of a man of average height. This frame is suitabl)7 braced by rods 26, and the lower ends of its side members are secured to the platform by bolts 27, which also secure a cross-bar 28, which extends from one side of the platform to the other. (See Fig. 5.) This cross-bar supports the lower ends of a pair of narrow vertically-disposed rotatable frames 29 and 30, which are formed at their upper ends with hubs 31, that extend through circular openings in the top of the frame 25. Each of the frames 29 and 30 comprises side members which are provided with vertical slots 32 near their upper ends and which are connected at top and bottom by short horizontal members. These frames carry vertical cylinders 33 and 34, the lower heads of which have integral projections 34A, which are squared at 35, as shown in Fig. 5. These squared portions 35 pass through corresponding openings in the bottoms of the frames and through pinions 36, which abut IIC -pistons 37, which are normally positioned a short distance above the bottoms of the cylinders, and air-inlets 38 are formed in the cylinders just below the pistons. 'l'he pistons are provided with' rods 39, which extend through the upper cylinder-heads and up through the hubs 3l of the frames 29 and 30. The rods 39 near their upper ends are each formed into a rectangular frame-like support 40, which, as shown in Fig. 2, may be accomplished by bending the rod so as to form onehalf of the support and then welding upon the rod a piece of corresponding bend, or, as shown in Fig. 5, by bending the rod as in Fig. 2 andA then bolting to the rod by bolts 4l a piece which is bent to correspond to the bend in the rod. The rods 39 are continued above the rectangular supports 40 and pass up through the hubs 31, as previously stated. Within the supports 40 are secured a pair of striking- arms 42 and 43, so as to have arocking movement therein. These arms comprise operating-cylinders 44, which are provided with inlets 45 at their rear ends, pistons 46, to which are attached rods 47, that extend out through the forward cylinder-heads and are provided-with padded or inflated mitts 47A, helical springs 47B, which are interposed between the pistons and front cylinder-heads, and cylinders 48, which telescope upon the forward half of the cylinders 44 and are attached at their forward end to the rods 47 and move with them. The cylinders 48 steady the movement ofthe rods 47 and prevent their being bent, as will presently more fully appear. The supports 40 of the piston-rods 39 are provided with laterally-extending lugs 40A, which pass through the slots 32 of the frames 29 and 30. These lugs normally lie at the bottom of the slots and prevent the pistons 37 of the cylinders 33 and 34 from closing the inlets 38 in said cylinders. As the pistonrods rise the lugs will also rise in the slots 32 and will serve to maintain the vertical position of the pistons. The rear ends of the cylinders 44 are secured within rock-frames 49, which are held in the support 40 by pivotpins 50, which pass through apertured lugs 51, which are formed centrally of the under side of the rock-frames. With the pins 50 as centers radial slots 52 are formed in projections 53 upon the upper sides of the rockframes, and pins 54 pass through the supports 40 and through the radial slots 52 and serve to steady the movement of the rock-frames and arms. The arms operate independently and are designed to have a swinging movement from right to left on a horizontal plane, an up and down rocking movement on the pivots 50, a forward striking movement, and an upward vertical movement. These movements are designed to be effected in rapid succession or in combinations of movements which are eected sumultaneously, such as a swinging, a rocking, and a striking movement, and I accomplish these various movements by cylinders which are supplied with compressed air at predetermined periods and which are provided with pistons having rods which form part of or are connected with the striking-arms and movable supports thereof, so as to effect these movements in the manner which 1 will now proceed to describe, beginning with the horizontal swinging movement of the arms.

Adjacent to the lower ends of the rotatable frames 29 and 30 are secured cylinders 55 and 56, having in lets 57 at their rear ends. These cylinders are provided with pistons 57A, between which and the front cylinder-heads are interposed helical springs 58, and rods 59 eX- tend from the pistons through the front cylinder-heads and beyond the heads. These rods are formed with or have secured thereto racks 60, which engage the pinions 36 at the lower ends of the rotatable frames 29 and 30. Thus when air under pressure is admitted to the cylinders 55 and 56 the pistons 57" will be thro-wn forward and will compress the springs tons to the rear endsof the cylinders, and the racks, which are carried thereby, will return the frames and arms to their normal positions. When it is desired to raise the arms vertically, air under pressure is admitted to the cylinders 33 and 34 through theinlets 38 and the pistons 37 are moved up, carrying the piston-rods 39, which in turn carry the arms 42 and 43 and the rock-frames 49, to which said arms are attached. 'hen the air exhausts from the cylinders 33 and 34, the arms drop by gravity to their normal position. The arms are rocked either up or down in the following manner: Upon the piston-rods 39 are secured suitable brackets or supports 61, which extend parallel with the rock-frames 49, and upon the outer ends of these brackets are secured cylinders 62 and 63, having pistons 64, which are normally positioned midway between the cylinder-heads and inlets 64A in the lower cylinder-heads. The rods 65 of these pistons have eyes 66 formed on their upper ends, which encircle slide-rods 67 upon the under side of the rock-frames 49. Now

to tilt the arms up air under pressure is admitted to the cylinders 62, and the pistons 64 are forced up and their rods 65, through their connection with the forward slide-rods 67 upon the under side of the rock-frames, tilt IOO IIO

the said frames on their pivot-pins 50, and at the same time the pistons in the cylinders 63 will be moved to the bottoms of the said cylinders, the arms being returned to their normal or horizontal positions, when the air exhausts from the cylinders 62. The arms are given a downward tilt by admitting air to the cylinders63, as will be apparent, and as the arms move in the arc of a circle and the piston-rods 65 move vertically the difference in direction of movement at the point of their connection is accommodated by the sliding connection between the piston-rods 65 and the slide-rods 67. The arms 42 and 43 are operated to deliver straight blows by admitting air under pressure to the cylinders 44, which forces the pistons 46 and rods 47 forward, the spring 47B being thereby compressed between the piston 46 and the front cylinder-heads. As the rods 47 shoot forward the cylinders or sleeves 48, which are attached to said rods, will slide on the forward portions of the cylinders 44 and will serve both to steady the movement of the rods and to prevent their being bent by a blow from the person exercising'.

The 'manner of controlling and delivering air under pressure to the various operatingcylinders at predetermined periods and of exhausting the same at predetermined periods is accomplished by mechanism which I will now proceed to describe.

Upon the rear end of the platform 17 is bolted a pair of standards 68, upon the rear ends of which is bolted an auxiliary air-reser- Voir 69, which is horizontally disposed. rlhis reservoir is tapped to receive a nipple 70, to which one end of a suitable air-hose is attached, and the other end of this hose is attached to a nipple 72, which is screwed into the lower end of the cross l2 upon the pipe 4 at -the outer end of the horizontal member 2 of the supporting structure. Thus air under pressure passes from the tank 3E through pipe 3D, nipple 3C, pipe 4, aperture 14 in track 13, nipple 72, and hose 7l to the auxiliary reservoir 69, and this reservoir is provided with a number of air-outlet valves 73, corresponding with the number of operating-cylinders. These valves are similar in construction and are arranged in line on a horizontal plane along the front portion of the reservoir. Each of the valves 73 comprises a body portion, having' a horizontal bore 74, which is intersected about centrally of its length by a vertical bore 75. The rear end of the valve is reduced and threaded, so that it can be screwed into the shell of the reservoir, and the forward end is provided with a suitable stuffing-box 76. The valve is practically in the form of a T, and the extremity of the vertical portion is threaded to receive a suitable pipe or hose coupler 77. A tube 78 is fitted into the bore 74, the forward end of which projects a suitable distance beyond the stuling-box 76. This tube is closed at both ends in any preferred way, but, as illustrated, by screws 79, between the ends of which and the ends of the tube are interposed as will presently be shown, the hole 82 will' register with the bore 75, while the hole 83 will communicate with the reservoir 69 and permit the air to escape through the bore 75.

Upon the forward ends of the standards 68 is secured a bar 85, having a row of horizontal threaded apertures, into which are screwed exhaust-valves 86. The valves face the Valves 73 and are the same in number, but are posiition'ed to alternate with the said valves 73.

In construction they are nearly like the airescape valves, each having a sliding tube 87 in its horizontal bore, which, however, is open at its rear end. and a hole 88, which registers with the vertical bore 88A of the valve when the tube is pressed in. Stuflng-boxes 89 are provided at the forward end of the valves, and springs 90 hold the valves normally in a closed position, being interposed between the stufiing-boxes and washers 91, which are held upon the outer ends of the tubes by screws 92, which also serve to seal the end of the tube. The tubes 87 may be retained within the bores of the valves by screws 87, which pass through the body of the Valves and engage slots 87B in the tubes. To the threaded ends of the valves 86, which extend through the bar 85, arev screwed Ts 93, to the horizontal bores of which are attached sections of air-hose 93, each of which connects at its opposite end with one of the operating-cylinders, as will be clearly seen by reference to Fig. l. To the vertical bore of each T is attached a section of hose 94, the other end of which connects with the coupler of the opposite air-escape valve 73. Thus when one of the air-valves is opened the air from the auxiliary reservoir passes out through the hose 94, attached thereto, and through a T 93 to the hose connecting with an operating-cylinder, and when the tube 87 of the exhaust-valve connecting with this T is pressed in the hole 88 of said tube will register with the bore 88A of the valve, which bore opens to the atmosphere, and the air will exhaust through said bore.

It is designed that the valves 73 and 86 shall be operated in combinations, so as to effect a variety of movements of the platform 17 and of the arms 42 and 43 simultaneously, and I accomplish this in the following manner: Upon the standards 68 and midway loetween the valves 73 and 86 is journaled a drum 95, having circumferential rows of IOO teeth 96, which extend in individual circles or bands around the drum, said rows of teeth alternat`ly registering with the valves 73 and 86. The teeth are secured to the drum by bolts 97, which pass through holes drilled in the drum, as shown in Fig. 10, and the holes are drilled close together, so as to accommodate a great number of teeth and so that the position of a tooth or of the teeth in one row may be varied with respect to the position of a tooth or of the teeth in any other or an adjoining row, said teeth being adapted to contact with and push in the tubes 74 and 87 as the drum revolves. Thus by setting the teeth to open a combination of valves either simultaneously or in rapid succession and so as to vary the combinations and the successive openings an ever-changing variety of movements and blows is accomplished by the machine, which will compel the person exercising therewith to be constantly on his guard in order to escape the blows of the striking arms or the forward rush or swinging movement of the platform. By reference to Fig. it will be noted that some of the teeth are much shorter than others, and the short teeth 96A occur in the rows of teeth which operate the valve-tubes 78 of the valves 73. These short teeth will move the tubes only far enough to partially open the valves, which will thus admit only a small quantity of air to the operating-cylinders or a quantity insufiicient to accomplish a full stroke or movement, as the case may be, of the mechanism'connected therewith, and this partial movement or feint is intended to accomplish the same purpose as would a similar movement by a human adversary.

The platform 17 is moved backward and forward in the following manner: To the rear end of the track 13 is secured a cylinder 98,-

having a double-headed piston 99, the rod 100 of which is connected at its forward end to the rear upright 18 of the platform. The piston 99 is spool-shaped, as shown in Fig. 14, and substantially half the length of the cylinder. To the under side of the cylinder and centrally located thereon is a casing 101, in

are formed in the cylinder, and asthe piston moves back and forth its heads will alternately strike the valve-stem 104 and oscillate the valve, so as to admit air alternately to the front and rear ends of the cylinder, the air exhausting from one or the other of the ports valve 102 :is in position to admit air to the rear end of the cylinder, and as the piston is moved forward the platform will travel forward ou the track 13 and remain in this position until air is admitted to the forward end of the cylinder, when the platform will be restored to its former position. It will be understood that as the air exhausts from this cylinder direct and not through one of the exhaust-valves 86 both movements of the piston 99 are accomplished by a single row of teeth 96, operating the tube of one of the valves 73. When the platform 17 and counterbalancingweight 16 are in their normal positions, the weight upon each sid'e of the pivotal point of the track is equalized; but the equilibrium would be destroyed when the platform is mov ed were it not for a corresponding movement of the weight 16 either toward or away from the pivotal point of the track, and this movement of the weight is accomplished in the following way: Adjacent to the ends of the track 13 are mounted sprocket-wheels 112 and 113, and upon the forward end of the weight 16 is secured one end of a section of sprocket-chain 114, which passes around the wheel 112, and is secured at its opposite end to a rod 115, which is attached to the forward platform-standard 18. A section of chain 116 is secured to the rear standard and passes up around the sprocket-wheel 113 and is connected to one end of a rod 117, which is attached to the rear end of the weight 16. Thus as the platform moves forward the weight will be drawn rearward a corresponding distance, and as the platform moves rearward the weight will be drawn forward, and in this way the weight upon each side of the pivotal point of the track is equalized.

It is apparent that the rods 115 and 117 could be dispensed with and chains of greater length employed or even a single endless chain, which would be secured to the weight and to the standards; but the construction illustrated is preferable, in that it does away with rattling and with the swinging motion which would be inevitable in a chain of such length and enables the tension upon the chainsections to be easily maintained, and thus prevent any lost motion.

The track 13, with the platform and weight, is swung in the arc of a circle by an operating-cylinder 118, in all respects similar to the cylinder 98. For the sake of convenience, however, this cylinder is turned to bring its disk-valve casing 119 uppermost, and the cylinder is irmlysecured to one side of the beam 2 of the supporting structure adjacent to the plate 7 upon the pipe 4. An air-supply pipe 120 extends from the inletof the casing 119 above and to the opposite side of the beam 2, and a hose 121 connects said' pipe with one of the Ts 93. The upper end of this hose, being near the pivotal point of the track and to TOO IIO

ISO

one side of the same, will not be in the way of the track in one direction of its movement and will be moved only a slight distance to one side when the track swings in the opposite direction. The piston-rod 122 of the cylinder 118 has a horizontal projection 123 near its forward end, which is adapted to engage the pins 11 on the plate 7. Then the pistonrod moves forward,this projection engages one of the pins 11 and swings the platform toward the right, and as the plate 7 revolves the other pin will come into position to be engaged by the projection as the piston moves rearward, and as it thus pulls upon the said pin the platform will be caused to assume its normal position. In Fig'. 13 I have illustrated another way of swinging the platform, and in this modification I employ a pair of cylinders 124 and 125, which are secured upon the rear end of the platform 17, one at each side thereof. These cylinders extend at right ang'les to the length of the platform and in opposite directions'and are inclined toward the floor. These pistonrods 126 and 127 are tipped with rubber, and as air is admitted to one or the other of the cylinders through the pipes 128 or 129 the rods will shoot out and strike the floor, and by successive strokes of this kind with a diminished supply of air the platform may be caused to move around intermittently, or by using the full force of the air it may be swung to its full limit. In order to relieve the platform operating' cylinder of strain when the platform reaches the limit of its movement in either direction, the plate 7 is provided with a stop 7", which contacts with the side of the beam 2, as shown in Fig. 9. In practice the track 13 will be suitably braced to prevent sagging' or lateral bending'.

In Fig. 11 I have illustrated a form of dummy which may be used instead of theA one shown in Figs. 1 and 2, which is adapted to receive head-blows only. The dummy shown in Fig. 11 comprises a head 24 and a body 24B, which are connected by a stout coil-spring 24C. The head is further connected by a coilspring 24D with a bracket 24E, which is firmly secured to the top of the rectangular frame 25. A coil-spring 24F depends from the bottom of the body, and any suitable means, such as a rod, may be attached to this spring and to the platform. This form of dummy admits of both head and body blows, and the springs permit a yielding' movement as the blows are delivered.

The operation of the machine is as follows: Compressed air is delivered to the tank 3 and is supplied to the auxiliary reservoir 69 by pipe 3D and hose 71. The drum 95 is revolved by a suitable motor 95, and the teeth engage and push in the tubes of the valves 73 and 86, admitting air to certain of the operating-cylind ers and exhausting it from others, either simultaneously or successively, and the arms 42 and 43 operate in the manner before described, while the platform is at intervals rushed forward or swung in the arc of a circle or given both movements simultaneously. Combinations of movements are given the arms independently of each other-such as an upward swinging, tilting, and striking movement-and this is accomplished by setting the drum teeth to simultaneously operate the valves, admitting air to the cylinders which elfectthe movements, or their movements may follow each other successively, while the movement of the other arm may be altogether different. The opponent stands in front of the machine and delivers blows to the dummy, endeavoring meantime to dodge or ward off the striking' and swinging blows of the arms and to be prepared for the rush or swing of the platform. The arms may be padded, if desired, to avoid injury, and theinflated rubber tube 21 upon the end of the platform will prevent injury to the ankles. A valve A may be placed in the pipe 3D to control the supply of air to the auxiliary reservoir. The lugs 40", which slide in the slots 32 of the rotatable frames 29 and 30, will not only steady the movement of the pistons 39, but will prevent them from being sprung or bent when a blow is delivered to the opponent. 1

The machine herein described is admirably adapted to the training of persons in the art of sparring, as all the movements employed by the professional boxer are produced as nearly as can be accomplished by a mere automaton, and to the professional man in training for a contest it affords means for exercising without the liability of injury.
