To all whom it may concern:

Be it k11OWI1 l3l1at I, MAURIOE J. AoHoR, a citizen of the United States,v residing at Marion, in'the county of Grant and State of Indiana, have invented certain new and useful Improvements in Rotary Snow-Flows, of which the following is a specification, reference being had therein to the accompanying drawing.

The invention relates to-rotary snow plows and has for its object to provide a snow plow that may be easily attached tothe front and end of a railway engine so that the same may be pushed-ahead of theengine and the snowand ice removed fromthe track.

Conveying the snow and ice rearwardly over -a conveyer to ahopper, thence depositing the same-to either or both sides of-the track at any angle desired.

A further object isto construct the plow so that it willtake the place of the front truck, of the engine or tractor which furnishes its-propelling power and also the power for operating the various mechanisms of the plow.

Afurther object'is to provide-a pivoted member, pivotally secured to the main frame of the plow, in which a rotary plow is carried and means whereby the pivoted member may be adjusted with relation to the road bed.

A further object of the invention is to provide a snow plow, having a pivoted member carrying a rotatable snow cutting member, meanshfor rotating the snow cutting member and a rearwardly extending conveyer pivoted to the rotary snow cutting member" and so,constructed that the lower endof the rearwardly extending conveyer will remain inits relativeposition to the rotary cutter when the pivoted-member is adjusted at various distances from the ground.

A further object bf the invention is to provide means whereby the necessary power for operating the various mechanisms of the" ;member comprislng arms 16 extendlng forsnow. plow will be furnishedxby the vehicle pushing the snow plowas a whole.

.A further object is to provide laterally disposed conVey-ers that may be swung longiunder bridges.

With the above and other ob ects in. View which will appear as [the description proceeds, thei'nvention resides in the details of "the precise embodiment of the invention herein described may be made within the scope of what is claimed without departing from the spirit of the invention.

Figure 1 is a side elevation'of the plow, showing the same attached to the front of a railway engine.

Fig. 2'is a top plan View of the plow showing the same detached from the engine.

Fig. 3 is a longitudinal vertical sectional viewthrough-the plow.

Fig. at is a sectional viewon line ll of Fig. 1.

Fig. 5 is an enlarged detail of a portion of the frame, showing the anechanism for operating the laterally extending conveyers.

Fig. '6 is a perspective view of rail scraper and ice cutter of the pivoted member.

Referring to the drawings, the numeral 1 designates a body frame and pivoted'to the front end thereof, by means of the bolt 3 is a truck 4.- of a conventional form. The truck 4 is provided with wheels5 adapted to engage and run on rails 6, how-everit is 'to be understood that where the plow is used on streets or roads and is being pushed by a tractor, that thetype of wheels may be varied. Secured to the end 6 of the body frame, by means of the bolt 7 is a rear truck 8 of a conventional-form, this truck is provided with wheels 9 similar to the wheels 5 of the front truck and are adapted to rest upon the rails. The'upper end of the bolt 7 is pivotally mounted in a bearing 10, of the portion 11, of a conventional form of engine 12. It will be noted, that the front truck of the engine has been removed and the rear end 6 of the body frame of the snow ;plow substituted therefor, the rear truck 8 of the snow. plow servin as a front truck for the pushing or propelling vehicle.

Pivoted at '13, to the forward .end' of the bodyframe 1 is api-votedmember 14, said the rotary druinQ-l. The drum 21 is provided with spirally arranged cutter-Ibars2'2,

which'are securedto the surface o'f' the drum by means of the screws 23, so that they may be replaced with ease. Keyed to one of the pintles 20, by means of the key 24 is a crank arm 25. A pitman rod 26 has one of its ends pivotally secured'as at 27 to the crank arm 25, while its other end is pivotally secured as at 28 to a cross head 29, which is in turn guided in its 7 movement in the orosshead guide 30, said guide being secured to the side of the body frame-1 by means of the rivets 31. A piston rod 32 is pivotally secured to the cross head 29 as at 33 and is reciprocated by means of the engine 34;, secured to the side of the frame 1 by the rivets 35. Steam is admitted to the engine through the steam chest 36, pipe 37 and flexible steam hose 38, which is in turn connected as at 39, to the steam supply pipe 40 leading fromthe engine to the steam chest 41. Valves 50 and 51 are provided controlling the supply of steam to the engine 34:. It will be seen, that when the engine 3 1 is in: operation, the rotary snow cutting drum will be revolved and its revoluble movement controlled the amount of steam supplied to the engine 34:.

A gear 52 is secured to one of the pintles 20 and meshes with a gear 53, rotatably mounted upon a stud 54 on one of the arms 15 and secured to said gear 53 and adapted to rotate therewith is a sprocket A. sprocket chain 57 extends around the sprocket 55 and sprocket 57 a which is keyed to the shaft 58, of the conveyer 59, said shaft 58 being rotatably mounted in bearings 60, of the arms 17. The conveyer 59 comprises sides 60*, the lower ends of which are pivotally secured to the shaft 58, while its other end rests upon andslidably engages the snow hopper 60 as at 61, the purpose of which will presently appear. Rollers 62 are secured to the shafts 58 and 63 and extending around said rollers and adapted to be rotated thereby is a conveyer belt 6i for conveying the snow to the hopper 60 It will beseen that when the drum is rotated. that the snow will be thrown rearwardly on to the moving conveyer belt 64: which moves in the direction of the arrow at and that the snow will be deposited in the hopper 60". Also it will be seen that ice plowed up by the plow 18 will be forced backwardly upon the moving conveyer belt and then deposited in the hopper.

The adjustmentof the pivoted member 14 in relation to the ground or surface of the rails isaccomplished by means of jack screws 65, threaded into lugs 66 integral with the body frame 1, their ends 67 engaging lugs 68 integral with the pivoted member 14;. Thus it will be seen that when the jack screws are rotated, that the pivoted member. 14:, will be forced upwardly or allowed to assume a position closer to the ground. If the cutters of the drum should hit an. 010. tru ti bl t, in h i the pivoted member will pivot upwardly and rise under its power, thereby preventing the breaking'of the cutters 0n the rotating drum.

The hopper 60 is provided with chutes 69, which discharge the snow to both sides of-the machine and on to conveyers 70 and 71. Brackets 72 support the hopper and maintain the same spaced from the body frame. The conveyers 70 and 71 comprise sides 73 and are provided, at their ends, with rollers 7 a, mounted on and adapted to rotate with shafts '7 5 and 76, extending around said shafts are belts 77, which move in the direction of the arrows b, so that the snow will be discharged to the sides of the machine. Secured to the shafts 75 are sprockets 76, which are rotated by means of sprocket chains 78, which in turn extend around sprockets 79 keyed to shafts 80 which rotate in the ends of the conveyers 7'0 and 71. U-shaped brackets 81, having upstanding. arms 82, supportinner ends of the conveyers and also have bearings 83 for the shafts 80. .Mounted in bearings 84 of the body frame l are verticalshafts 85,

said shafts forming a pivotal point for the brackets 81 and upon which the conveyers pivot when the conveyers are swung at dif ferent angles relative to the bodyv frame. Secured to the upper ends of the vertical shafts 85 are bevel gears 86, which mesh with bevel gears 87 which are keyed to the shafts 80. Sprockets 88 are keyed to the vertical shafts 85 and extending around said sprockets and the sprockets 89, keyed to a vertical shaft 90, mounted in a bearing 91 of thebody frame 1 are sprocket chains 89*. Keyed to the upper end of the vertical shaft 90 is a crank arm 92 and pivoted to the end of the crank arm 92, as at 93 is a pitman rod 94. The other end of the pitman rod is pivoted as at 95 to a crosshead 96, slidably mounted in a crosshead guide 97, said cross head being reciprocated vby means of a piston rod 98, operated by the engine 99, which is secured to the body frame by means of the bolts 100, steam being. admitted to the steam chest 101 of said engine through the branch pipe 102 and under control of the valve 103. I

It will be seen that when the crank arm is rotated in the direction of the arrow 0, that the conveyer belts will move in the direction of the arrow b and that the snow 1 bodyframe, without dis- 1 body frame 1, by means of the pins 104, which pass through apertures 105 in the brackets 81 and through the apertures 106 in the body member 1. It will be seen that the conveyers may be swung to the sides of the frame, when the pins 104: are removed by means of the conveyer driving mechanism.
