LEVELING-MACHINE.

T 0 all 'whom it may concern Be it known that I, VARREN FRAsiER, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Leveling-Machines; and I do hereby 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.

The present invention relates to leveling machines, and more particularly to that type of machine which comprises a. leveling roll and a cooperating shoe supporting jack relatively movable to change the relative longitudinal position of the roll and jack.

The object of the present invention is to provide la machine of the above character which is simple in construction and which is capable of securing uniformly good results upon varying classes of shoes.

lVith the above object in view, one feature of the invention contemplates the provision* 1n a machine of the class described having a leveling roll provided with one or more striking faces and a shoe supporting jack, of means interposed between the roll and shoe sole to receive the direct blows of the striking faces as the roll is rotated. y

Still further features of the invention consist in certain novel features of construction,

combinations and arrangements of parts hereinafter described and claimed, the advantages of which will be obvious to those skilled in the art from the following description. 1

'In the accompanying drawing,la side elevation of a machine embodying the several features of the invention in their preferred form is illustrated. v

The machine shown in the illustrated embodiment of the invention is designed more particularly for operation upon the soles of turn shoes and it is considered desirable when leveling these shoes to deliver a series of blows upon the sole of the shoe to beat out the sole and cause it to conform to the curvature of the last. conveniently performed by a continuously rotated leveling roll provided with a. plu-A rality of striking faces which are arranged to deliver a series of rapid blows upon thesole as the shoe supporting jack is moved Specification of Letters Patent.

under the roll. In the present invention, the beatingkout operation is satisfactorily per` formed and the sole is bedded upon the last without marring or otherwise injuring the surface by the provision of a flexible or ref silient shield which engages with the sole and which is arranged to receive the direct blows of the striking faces as the roll is rotated. In the simplest and most efficient form of the invention which has yet been devised, this shield consists of a curved metallic band which surrounds the lower portion of the roll and which is interposed between the roll and shoe in such a manner that when the roll is rotated the striking faces successively contact with the lowest portion of the band which engages the shoe.

The machine consists principally of a shoe supporting jack 2 pivoted to the machine frame at l and a leveling roll 5 journaled in the outer free end of a roll supporting arm 6 which is p'ivoted in the upper portion of the machine frame at T. The roll v5 consists of a plurality of small rolls 8 which are arranged to successively act upon the sole as the roll is revolved and the faces of which constitute the striking faces of the roll A continuous rotation is imparted to the leveling roll in the usual manner from a main drive shaft 10, a drive pulley 11 mounted thereon, and connecting belts 12 and 13. The roll is pressed downwardly upon the shoe sole by a tension spring 16 which is connected to the frame at its lower end by a link 17 and to the roll carrying arm at its upper end b'y an adjustable connection consisting of a threaded link 18 and'hand wheel 19 arranged to adjust the tension of the spring g and vary the pressure of the roll upon the work. 'lh-e downward movement of the roll when the shoe is removed from engagement therewith is limited by a stop rod 2O connected at one end to the frame of the machine and at its opposite end through an adjustable hand wheel 2l with a rearwardly extending portion 9.2 formed upon the arm 6.

The leveling roll 5 is journaled in a head which is swiveled in the outer-end of the roll carrying arm in order that the roll may be tilted laterally and cause the sole to conform to the curvature of the last in cross section. A simple and efficient mechanism under the control of the operator ris pro` vided for securing this lateral inclination which consists of a toothed segment 26 pivoted at 27 upon the supporting arm 6 and meshing with a bevel gear 28 pinned to the inner end of the head 25. The toothed segment 26 is oscillated by a handle 30 extending into a position conveniently accessible to the operator and by manipulating the handle in a vertical direction any desired lateral inclination may be imparted to the roll. As the leveling roll 5 is rotated, the direct blows of the rolls 8 are -received upon a metallic band or shield 31 which is supported slightly eccentric to the roll 5 in order that the small rolls 8 shall only contact with the lowest portion of the band which engages the sole. The curved band 31 is preferably formed of resilient sheet metal which is arranged to yield or give slightly when each roll Icontacts therewith to4 thu-s transmit the blows of the leveling roll indirectly to the surface of the sole. causing the sole to be leveled without mai-ring or injuring the surface of the same. In order to vary the force with which these indirect blows are delivered upon the sole, the position of the band relative to the roll may be adjusted, thereby causing the rolls to strike with a greater or less degree of force upon the band as the leveling roll 5 is rotated. The band 31 has one end pivotally secured at 32 to the head 25 and its opposite end is adjusted relative to the head by a stop screw 33 bearing against the upper end of the band. The end of the band is enlarged and provided with a rectangular slot which embraces a square stud 34 secured in the head 25, thus affording provision for a vertical movement of this end of the band relative to the head. It will be notedv that when the machine is in operation.l the lowest portion of the band 31 engages with the shoe sole and the pressure imparted by the spring 16 causes the band to be forced upwardly with relation to the roll until its movement is limited by the stop screw 33 which positions the band with relation to the leveling roll 5 and consequently determines the force or extent of the blows which are delivered by thev small rolls 8 upon the band.

It is a desirable requisite in machines of this character that the shoe supporting jack may he readily adjusted to acconnnmlate varying sizes and styles of shoes. that the shoes may be firmly clamped in position upon the jack. and that when clamped upon the jack they shall always be supported in the same position relative to the leveling roll. The jack 2 consists of a supporting bed or frame 35 pivoted to the frame of the machine at l and having the usual heel post 36 and toe post 3T slidingly supported there on. In order to conveniently adjust the positions of the heel and toe posts to accommodate varying sizes of shoes, they are connected together by an adjusting rod 38 having its ends threaded in opposite directions and connected with the posts 36 and 3T to cause the simultaneous movement of the posts toward and from one another as the rod 38 is rotated in either direction. heel post 36 is or' the usual construction having a last pin -lO pivoted thereto at i1 and provided with mechanism for actuating the .last pin which comprises a pivoted cam plate i2 engaging with the lower end of a sliding pin i3 which contacts at its upper end with the -under side of the last pin 40. 1n order to secure the same relative position of the shoe and leveling roll independently of the size of shoe, a heel gage l5 is pivotally secured at i6 to the bed of the jack and has an inturned upper end arranged to project over the heel of the shoe, serving to both position and clamp the shoe when the machine is in operation. lith this construction, the heel gage is permanently fixed in a vertical positionrelative to the jack and also to the toe post 37 which has no provision for vertical adjustment. The heel post of the ack is adjusted vertically to move the shoe into engagement with the gage 45 by mounting the post upon a slide 50 which is moved vertically by an operating cam 51 fulcrumed at 52 upon the bed 35 .and provided with a handle 53. The operating cam 51 is provided with a curved operating.; face engaging with the lower end of the slide and designed in such a manner that when the heel ofthe shoe is forced against the gage 45 lthe cani will retain it in this position until released by the operator. It will be noted that the adjusting rod 38 is journaled in the slide 50 and moves vertically with the slide relative to the toe post 37. The adjusting rod 38 is threaded into a nut which -is slidingly mounted in dove-tailed ways 56 formed upon the side ot the toe post 3T, thus causing the toe post to move toward and from the heel post when the rod is rotated, but allowing the rod to be moved vertically relative to the toe post without disturbing the relative positions of the toe and heel posts.

In the present machine, the actuating mechanism is arranged to impart one complete oscillation of the jack back and forth beneath the roll and the machine is then automatically stopped with the. roll positioned apj'iroximately above the toe ot the shoe. After the machine has been stopped` the jack is conveniently disconnected from the actuating mechanism to allow it to be swung out from beneath the roll and facilitate the removal ot' a Finished shoe and the application ot' a new one. The jack is oscillated by a rotary path cam (30 secured to a shaft 61 and rotated from the main drive shaft through the pulleys G2 and G3 and a connecting belt 64. The jack is oscil- The lated from the lcam l60 through a connecting rodo which is connected to a slide 66 having provision for adjustment to and from the fulcrum of the jack to vary the. extent of oscillationilnparted to the jack by the actuating cam. The slide 66 is supported in dove-tailed ways 67 formed in the bed 35 and an operating lever- 68 is connected thereto to adjust the position ofl the slide. The slide is retained in any adjusted position by a toothed quadrant 69 which is engaged by a spring pressed latch 7() supported upon the adjusting lever. The drive shaft is actuated by any suitable form of clutch mechanism which is controlled by a shipper rod 75 connected to a forked clutch lever 76 through a bell crank 77. The shipper rod 75 is normally moved to engage the clutch by 'a spring 78 interposed between a bearing member 79 formed upon the frame of the machine and a collar 8O secured to the shipper rod. rlfhe shipper rod is automatically moved at a predetermined time to disengage the clutch by a lever 81 pivoted centrally to the frame at 8:2 and having its upper and lower ends connected respectively with the cam 60 and engaging with the end of the shipper rod T5. The upper end of the lever 81 is conveniently connected to the rod 65, thus forming a support for the end ofthe rod and causing the lever to be oscillated at the proper time to automatically disengage the clutch by the cam 60. In order to. start the machine, the end of the shipper rod T5 must be removed from engagement with the lever 81 and to this end a memberS is hinged to the free end of the shipper rodand is normally positioned in alinement therewith. A treadle rod 86 is journaled in the frame of the machine below the shipper rod and is connected therewith by a crank arm 87 and connecting link 88, thus causing the free end of the member 85 to be swung clear of the lever 81 when the treadle 86 is oscillatedf 'ith this construction, it will be noted that the machine may be started by swinging the member 85 out of its normal position and after the machine is started, if the member is then moved back to its initial position the machine will be automatically stopped at the completion of a single cycle, or by allowing the member to remain in its raised position, the machine will operate for' an indeterminate length of time, completing any desired number of c vcles.

In order to allow the jack to be con veniently disconnected from the actuating mechanism, the rod is provided with a lateral stud 89 which is engaged by a hook 90 supported upon the slide 66. An operating lever 91 is pivotedto the slide above the hook and is connected therewith in any suitable manner to disengage the hook from the stud 89 and allow the jack tobe swung clear of the roll when the machine is at rest. In order to hold the rod 65 in engage' to normally maintain the stud 89 in en-l gagement with the hook 90. l
