STREET-S'WEE'PER.

SPEClFICATION forming part of Letters Patent No. 656,210, dated August 21, 1900. Application led December 1.5, 1899. Serial No. 740,449. (No model.)

To all whom it may concern:

Be it known that I, ALPHONSE PIToN, a subject of Her Majesty the Queen of Great Brit! This invention relates to street-sweepers;

and one object is to provide an apparatus of this character which is especially adapted for removing ice and snow from car-tracks.

A furtherobject is to provide such an ap,- 'paratus with means whereby it may perform the work of cutting the ice vand snow only, the sweeper being adapted to be raised and held in its elevated position.

A further object is to provide an apparatus of this kind which is strong and durable, so as to be able to withstand the rough work for which it is intended.

A further object is to provide such an apparatus with means whereby the snow and ice or dirt may be automatically'depositedl to one side of the car-tracks as the work of sweeping progresses.

Finally, the object'is'to provide an apparatus which 'is simple in construction, efficient in operation, and economical to manufacture. A

To these ends the invention consists in an apparatus for removing snow and ice from car-tracks,"constructed substantially as hereinafter illustrated and described, and defined in the appended claims.

Referring to the drawings, in which similar letters of reference indicate similar parts throughout the several views, Figure 1 is a plan view of the apparatus in which the invention is embodied. Fig. 2 is a side elevation thereof. Fig. 3 is a vertical central longitudinal section. Fig. 4 is a plan viewed from below. Fig. 5 is a cross-sectiony on the" line 5 5 of Fig. 2, parts beingshown in `eleva- 5o tion, looking toward'the'front'end of the car. In they drawings, A represents the body of a car, which may be of any ordinary or pre- ;ferred construction, but, as shown, is an open car operated by electricity. The front end of the car'is shown as provided with an ordi- 55 naryv form of motor A. Upon the rear axle and adjacent to each rear wheel is fixed a gear c. and a', which mesh with gears a2 and y :0.3, 'fixed Vupon the shaft co4, while at each end and at the center of said shaft a4 are fixed 6o sprocket-wheels a5, a6, and a7. Th'e gears a? and a3 mesh with gears as and a9, fixed upon the shaft am, and the last-named gears mesh with gears a and @12, fixed upon the shaft als. Upon each end of the shaft L13 is fixed 65 a sprocket-wheel@14 and @15, which are con-. nected by sprocket-chains am and @17 to the sprocket-wheels als and al, fixed to the ends of the shaft d20, which is journaled inthe hood B and carries the broom b. The hood 7o B is provided at each end with a supporting` arm b', which are revolubly yconnected at their upper ends to the shaft als. An operating-lever b2 is pivotally mounted in a standard b3, fixed upon the car-platform. To the outer end of the lever b2 is loosely secured a metal bail b4', the lower ends of which engage in perforations 4formed in the ends of the hood B. B y this means the hood B, and with 4itthebroom b, may be raised up out of con- 8o tact with the` ground wherever it is so desired.l

The hoodB is provided at the lower portion of its inner end with an inclined chute B', which communicates withV that portion of the hood carryingthe broom. The inclined chute B is closed at its upper end, *while the lower end is open and extends lto point near l the ground. By reason ofthe length of. the shaft am and the corresponding width of the hood B the open end or spout of the chute 9o Bextends to a point some distance Zbey/ond the rails of the tracks, thus permitting the dirt, snow, dto., to be 'deposited away from the rails and leaving a wide clean roadsurface.

Upon each side of the car-body and imlnediately in front of the rear axle thereof is ixed a depending supportingarm D, in the lower ends of which is journaleda shaft d,

and upon the central portion'ofths shaftis 1c@ fixed a sprocket-wheel CZ, c'onnected'by a sprocket-chain d2 to the sprocket-wheel a on the shaft a4. Upon the shaft d is lixe'd a series of parallel bars cl3, arranged spirally thereon, and between each pair of said bars d3 is secured a series of curved hooks d4, having sharp cutting-points, which hooks by reason of the spiral arrangement of the bars cl3 are inclined toward the outer sides of the car, thus tending in operation to throw the broken ice, zc., away from the track. Each series of bars and hooks are divided by the sprocketwheel d', and the series on one side of said wheel are inclined in the opposite direction from those on the other side of' said sprocketwheel.

Upon each side of the car-body and in front of the shaft d is secured a downwardly-extending support E, having a vertical recess e, with undercut sides, forming a guideway for the adjustable arm E, the lower end of which is extended laterally, forming a bracket e', in which is journaled the shaft e2. A sprocket-wheel e3 is centrally fixed upon said shaft c2, and between said sprocket-wheel and the outer portion of the bracket is secured upon said shaft a series of parallel bars e, arranged spirally thereon. A series of curved hooks e5, having sharp cuttingpoints, is secured between each pair of said parallel bars, which hooks, by reason of the spiral arrangement of the said bars, are inclined toward the outer sides of the car, thus tending in operation to throw the broken ice, die., away from the tracks, being in all respects constructed and operating in a manner similar to the hooks d* on the shaft d. A protecting hood or shield E2 is secured to said bracket e' and extends over the hooks c5.

Upon the inner side of the arm E is a' lug e6, which is pivotally connected to the end of an operating-lever F, which is pivotally supported in a suitable standard F', fixed upon the car. The lever-handle is provided with suitable openings, through which a pin f is inserted and passed through openings in an upright f', whereby the lever is secured in its adjusted position. By means of this construction it will be evident that the hooks e5 may be lowered into or raised upout of operative contact with the ice. Sprocket-chains e7 connect the sprocket-wheels e3 with the sprocket-wheels a5 and a7 on the shaft a4.

The foregoing description renders unnecessary a detailed description of the operation of the apparatus, it being obvious that the forward movement of the rear wheel of the car causes the broom and the several sets of cutting-hooks to rotate by means of the train of intermeshing gears and the sprocket wheels and chains.

The hooks d4 serve to cut the ice, snow, dac., from between the rails of the tracks, While the hooks e5 perform the same work just outside the rails. The broom sweeps up the broken ice, dsc., and deposits it into the inclined chute B', by which it is carried beyond the rail, leaving a wide clean space, which extends beyond the outer rail of the tracks.

There are many Yfeatures shown on the drawings which are common to cars of this construction and which need no detailed description of their construction and operation, as they do not pertain to my invention and are shown only that a complete car be shown having the necessary equipment for carrying out the purpose of a street-cleaning apparatus applied to a car. Such, for example, is the brake mechanism G, the track-sanding device ll, the trolley-beam I, and the device J for steadying the front axle.

While Ihave herein shown a preferred form of carrying my invention into effect, yet I do not desire to limit myself to such preferred details of construction, but claim the right to use any and all modifications thereof which will serve to carry into effect the objects to be attained by this invention in so far as such modifications and changes may fall within the spirit and scope of my said invention.
