SNOW MOVING AND DESTROYING APPARATUS.

" Application fled April a, 1925. serial m. 20,411. 7

To all whom it may concem:

Be it known that I, Rosana- H. Senouems, a citizen of the United States, residing at Oakmont, Upper Darby in the county of Delaware an State of Pennsylvania, ave invented certain new anduseful Improvements in Snow Removing and Destroying Apparatus, of which the following \IS a specification.

My present invention has reference to a snow removing and destroyin apparatus and has for its primary object t e provision of a machine for removing snow and ice from streets and roads, in an expeditious and satisfactory manner.

Another object ,is the provision of an improved means for scoop ng snow from a street or road, melting it and conducting the water eliminated from the snow away from the machinery to deposit the same in thedgutter at either 'side of the street or roa Another object is the provision of a motor propelled apparatus for removing and destroying snow in which a novel combined brush and combined cutting means is employed for gathering and directing snow from the street onto means that deliver the said snow to a triturating mechanism which also compresses the material, and in which means isemployed for reducin the trimrated mass into a fluent body or delivery through either side of the apparatus.

Another object is the provision of a motor driven apparatus for this purpose which carries at its forward end a vertically adjustable scoop of a novel construction, the said scoop being rovided with snow andice cutting teeth an having arranged forward of said teeth combined brushing and cutting means for delivering the snow intothe scoop, the said scoop being further provided with revoluble means for directing the snow to a triturating mechanism of a novel construction, and wherein the massed and pow-' dered snow is melted by heat delivered thereagainst, and the water eliminated from the snow is delivered from either side of the machine in accordance with the will of the operator.

Another object is the provision 'of'a snow removing and destroying apparatus-in which the mechanism constituting the same s arranged on a motor propelled wheeled body, of a novel construction, and in which a second motor is employed for operating said ers whose flames melt-the collected snow that the water eliminated therefrom may be delivered through either side of the machine and in which simple means is employed for swinging the manifold pipes of the burners to arrange the same 1n horizontal position sothat the flames therefrom' will not be directed against the triturating device associated with the destroying mechanism and whereby the extinguishing of the burners will not be necessitated when no snow is received in the apparatus, or when the device is lpropelledfrom place to place.

A still-furt device of this character, 0 a combined snow gathering brush and cutter disposed forward of rotary brushes which deliver-the snow into a destroying mechanism, and in which the gathering brush is caused to turn at a slower rate of eed than the directing brushes, the latter belng also rotated at different speeds.

A still further object is the provision in a snow removing and destroying apparatus of fluid burners for directing the flame against gathered and triturated snow in which an air pump is actuated by the travel of the device forsu plyin airto the oil tank and reservoir, an may be directed toward or away from the gathered snow in an easy and expeditious manner.

Another object is the provision of a novel er object is the rovision, in a I in w 'ich the burner nozzles construction of outletpipes for water eliminated from the snow gathered in the machine and in which and ipes may be arranged at any desired ang c with res the .sides of the machine, and furt er in which the delivery to either of said pipes is controlled by a simple valve mechamsnr readily actuated b the operator.

A still further 0 ject is the provision of a snow removing'and destroying a paratus that is mounted on a motor ro ed body and in which all of the m constitto' .- tutii g the apparatus is controlled from the (ab f the body, and also wherein the propelling mechanism of the said body is llkewise controlled from the cab.

For a full and comprehensive understanding of the invention, reference is to be had to the accompanying drawin s in WhlCh there is illustrated a simple and satisfactory embodiment of the improvement reduced to practice.

As disclosed by the drawings, I make use of a motor-propelled vehicle, preferably in the nature of a truck 1. The body of the vehicle may be covered, but the front thereof is PI'OVldGd with a cab 2. In this cab there is a drivers seat and the control for the steering and propelling mechanism of the truck. The. truck has its forward end mounted on guide wheels 3, but its rear or propeller wheels are in the nature of endless membe'rs or caterpillars. The caterpillar belt is provided with the usual cogs, and the said belt travels around two spaced wheels, one of which having its axle directly connected to the drive shaft from the motor 4. The caterpillar traction members are indicated by the numerals 5, and the lower lead of the endless belt therefor is held in ground-contacting engagement by means 6. This means consists of spaced rollers mounted on a vertically adjustable shaft or standard. I

On the to of the vehicle or truck there is an oil tan 7 which, at its forward end, is divided by a partition into a gasoline tank S. The gasoline is, of course, fed to the motor 4 in the usual manner, and is also fed to a second motor which will hereinafter be described.

On the to of the oil tank 7 there is a gauge 9, am the outlet pipe 10 for the oil tank have their passages controlled by valves arranged in suitable casings 11. The stems 12 for the valves project through suitable openings in the top of the oil tank 7 and are eccentrically or otherwise connected with operating rods 13. There rods lead to the cab 2, and each of the said rods is provided with an operating or control handle 14. Of course both the oil and the gasoline tanks are provided with suitable inlets which are normally closed.

Swivelly connected with each of the oil outlet pipes 10 is a pipe 15. Each of the pipes 15 is mounted for turning in suitable bearings 16. The pipes 15 are longitudinally arranged, but the end pipes are disposed below the central pipe. All of these pipes have ends which lead into the cab 2, the said ends, of course, being closed. On

each of the closed ends there is an actuating swung to bring one of their edges into engagement with one of the contacts 21 on each of the segments 20 to arranged the burners or nozzles 22 in a downward and angular direction with respect to the bottom of the truck. By simply swinging the levers so that the same will engage with the opposite contacts on the segments 20 the burners 21 will be sustained substantially horizontally. This is an important feature of the invention which will presently be manifest. Below the burners 22 the truck or vehicle 1 is provided with a longitudinally extending trough 23, the bottom of which being reticulated or provided with spaced openings 24 and the rear thereof being closed. J ournaled in a suitable bearing opening in the closed end 25 of the trough 23 and 111 a bearing 26 at the forward open end of the trough there is a shaft 27. This shaft provides the operating medium for the triturating mechanism of the. improvement. The triturating mechanism includes a grinding screw 28 which is, of course, spirally wound around and secured to the shaft 27 and spirally arranged mutilating blades 29 at the forward or receiving end of the screw. f

The trough 23' terminates in angle side portions 30 which are secured directly to the sides 31 of the vehicle '1. The sides 30 are rovided with inwardly arched flanges 32 isposed o posite the end burners 22, and these arcged members are in the nature of uides for directing the .flame of the said 'urners away from the triturating .device when the manifold pipes15 are "swung tobring the burners to horizontal .valve 36. The shaft 35, when turne position, as when no snow has been deliv: ered' into the triturating device or apparatus and when 'the vehicle is to be propelled without directing the flame against said "apparatus.

.. mu'nicating with the spout 33, there is a ate to bring'the valve 36 a inst either of'the side walls provided by t e passage between the shaft 35. On this shaft there is a spout and duct, will direct melted snow to either side of the vehicle. Thisis ecial- 1y desirable, inasmuch .as the-vehic e will travel adjacent to the curbs of a street or the, gutters of a road so that the water eliminated from the'snow will be directed nearest the .curb or gutter of a street or road. 1

In an instance where'the vehicle is ar-,

ranged a considerable distance" from the gutter of a road or street, and as illustrated in Figures 13 and 14 of the drawings, there is connected to the ends of the duct 34 outlet pipes 37. Each of the pipes 37 has its inner end pivotally connected to a beam 38 which is revolubly supported on the sides of the vehicle 1. The beam 38 has an out-v standing arm 39, braced to the said beams by means 40. The pipe members 37 have secured thereon collars or the like to which are connected flexible elements 41 trained through an eye member42-on the arm 39.

Each beam 38 has secured thereon an angle arm 43, and to each of these arms 43 there is secured a rod 44. Each rod'44 is pivotallv connected'to the angle end of alever 45. Each lever is pivoted to a segmental rack 46. Each .lever carries a hand-actuated spring-influenced pawl to engage with the teeth of the rack 46. By this arrangement it. will be noted that the pipe members or spouts 37 ma}; be arranged against the sides of the vehicle or disposed at any desired outward angle with respect thereto.

Hingedly secured, as at 47 to the bottom of the'trough 23 there-is a scoop 48. The scoop has its inner end of a. substantially rectangular formation, 'and' is from thence gradually widened to its outer end.';- The' scoop has flanged sides and a top. 7 The scoop, at the widened mouth thereof,-has its lowerv walk-provided with cutting elements in the nature 'of saw teeth 50. The side members 51 of the vehicle frame roject a suitable distance beyond the ca 2 {and are each provided at its outer end with an upstanding portion or standard 53.-

These standards are ;preferably connected at their upper ends. he standards 53 rovide bearings for a shaft 54. On the sldes of the scoo) 48 there are secured, preferably by lin s '55, flexible elements such as chains 56. Each of these chains is secured 1 around the shaft 54. The shaft 54 has keyed thereto a toothed wheel 57. This end ground-engaging rollers 62.

The sides of the scoop have brackets pro-' jecting from the forward or mouth end thereof, and these brackets provide bearings for the rounded end of the cross-sectionally squared shaft 63. On the squared portion lot the shaft there is removably secured the ground-engaging street contacting rotary brush of'the improvement. The brush is made up of broom'sections 64 that have arranged therebetween cuttin sections 65. The cutter sections or members are in the nature of metal spiders each having arms 66 radiating from the center thereof and.

terminating in sharpenedcutting edges 67.

The hubs of the broom or brush sections and those of the metal cutting sections have squared bores so that the same may be easily arranged on or removed from the squared portion of the shaft 63. This ground-contacting rotary sweep, in connection with the cutting tooth 50 of the scoop 48 are important features of the invention.

Journaled in suitable bearing openings between the sides, and adjacent to the mouth of the scoop 48, there is a shaft 66, and fixed on this shaft there is a rotary brush 67.' At the straight inner end of the scoop 48 there is also journaled between the sides thereof a shaft 68 which carries a brush 69.

The" numeral 70 designates a motor of the internal combustion type, such as is true with respect to the motor 4. The drive wheeldisposed opposite a similar sprocket wheel which is secured on the shaft 27 of the triturating device. Around these sprocket wheels there is trained a sprocket c ain 72. Thus the drive shaft 71 of the motor 7 0 imparts motion to the triturating mechanism.

On the shaft 71 there is a gear 73, in mesh with a small gear 74 whose shaft is journaled in a suit-ablebearing on one of the side members of the frame of the vehicle. The shaft for the gear 74 has secured thereon a sprocket wheel disposed opposite a larger sprocket wheel on a shaft 75 which is journaled in suitable bearings 76 on the.

' and secured on the shaft 66 there is a larger sprocket wheel. Around these wheels there is trained an endless sprocket chain 79. On the outer end of the shaft 66 there is secured a comparatively small sprocket wheel, and on the end of shaft 63 there is secured a larger sprocket wheel. Around these sprocket wheels there is trained an endless chain 80. By this arrangement it will be noted that to the sweeping brush 64 is imparted a comparatively slow rotary movement, the

brush 67 a faster movement, and the brush 68 a still faster movement. In this manner the brush 64 will have ample time to sweep into the chute all of the snow gathered thereby and cut by the teeth 50, the brush 67 delivering the said sweepings upwardly in the chute toward and in contact with the brush 69, and the said brush 69 rapidly delivering the snow and sweep-' ings to the snow destroying apparatus previously described.

As the gas control and the wiring for the motors 4 and 70 are of the well known type and are controlled by mechanism forward of the drivers seat in the cab, a detailed description thereof will not be at tempted.

The shaft 71 for the motor 70 operates an air pump 81, the said pump having a pipe connection 82 with the oil tank 7 and whereby the air acting on the oil in the said tank 7 serves as a forced feed for the burners 22 in the manifolds 16. The air .conducting pipe 82 is preferably valve-con- The simplicity of my construction and the operation thereof, will, it is thought, be perfectly apparent to those skilled in the art to which the invention relates. The snow swept by the ground brush which has the metal spiders associated therewith, will, as previously inferred, be effectively broken and delivered into the chute and from thence the said snow will be delivered by the brushes 67 and 69 into the triturating mechanism. The'fiame from the burners reduces the triturated material into a liquid mass and this liquid is delivered to either side of 'the machine as desired. The lighted burners at all times heat the device sutficiently to prevent freezing or clogging of the material therein, and the improvement may be mounted upon any ordinary truck construction.

The invention is, of course, not to be restricted to the precise detailed features of construction herein set forth as such changes therefrom as fall within the scope of my claims may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.
