22 indicates a brace one end of which is secured to the bracket 18 and the other to the bottom of the car.

23 indicates a block which is adapted to enter the slot 21 and slide freely therein and is provided with a journal in which the axle rotates.

24 indicates lugs which are journaled upon the axle 15.

25 indicates chains which are secured atone end of the lugs 24, pass over sheaves 26, and are fastened at their'other ends to a shaft 27 below the bottom of the car, which is journaled at its upper end to the bottom of the car and at its lower in a block 28, which is supported by a brace 29.

30 indicates a gear which is keyed or otherwise secured upon the shaft 27 and meshes with a gear 31. The gear 31 is keyed or otherwise secured to the lower end of a shaft 32, which extends vertically through the base of the car.

33 indicates a block in which the shaft 32 is journaled.

34 indicates a ratchet-wheel which is keyed or otherwise secured to the shaft 32.

35 indicates a pawl which is pivoted on the upper surface of the block 33 and is adapted to engage the ratchet-wheel 34.

36 indicates a collar which is keyed or otherwise secured to the shaft 32 and operates to hold the ratchet 34 upon the shaft 32 and prevent longitudinal movement thereof, so that the shaft 32 is supported 011 the block 33.

37 indicates a brace through the upper end of which the shaft 32 passes.

38 indicatesa hand-wheel which is fastened on the upper end of the shaft 32. When the shaft 32 is rotated by the hand-wheel 38 in the proper direction, the chains 25 are wound upon the shaft 27, and the axle 15, carrying the brushes, is lifted to any required position and held by the engagement of the pawl 35 with the ratchet 34. When it is desired to lower the brushes, the pawl 34 is disengaged in the usual way, permitting the rotation of the shafts 32 and 27, and the brushes drop by their own weight, the blocks 23 sliding in the slots 21.

39 indicates a driving-shaft which is journaled in suitable bearings 40 above the floor of the car and extends diagonally across the car parallel with the brush-axles 15 and is driven by any appropriate mechanism in the car, which may be connected, for instance, with the sprocket-wheel 41, secured to the driving-shaft 39.

42 43 indicate sprocket-wheels which are rotatably mounted upon the shaft 29 and are connected by means of sprocket-chains 44 with the sprocket-wheels 16 upon the brushaxle 15, passing through suitable openings 45 in the floor of the car. In Fig. 4 only one of these chains is shown in place, the other being removed for convenience of illustration.

46 (see Fig.2) indicates hoods or casings of ordinary construction to protect the sprocketwheels 42 43 and the sprocket-chains 44.

47 indicates a hood or casing of ordinary construction to protect the sprocket-wheel 41.

48 and 49 indicate clutch members which are feathered upon the shaft 39, so as to slide to and fro thereon, and are adapted to engage with corresponding clutch members 50 and 51 upon the sprocket-wheels 42 and 43, respectively.

52 and 53 indicate levers which are pivoted upon supports 54 and 55 and engage with the clutch members 48 and 49, respectively.

By the moving of the levers the clutches are thrown into and out of engagement, so that either one or both of the sprocket wheels 42 43 may be engaged and rotated by the rotation of the driving-shaft 39. In ordinary practice only one will be used, driving the broom at the forward end of the car, according to the direction in which the car is running, the other being thrown out of operation, thoughit is obvious that the other broom may be rotated to assist in the work if necessary.

That which we claim as our invention, and desire to secure by Letters Patent, is-

1. In a sweeper-car, the combination with a car-base having a diagonal end extending across the car-body from side to side thereof in a rectilinear diagonal line,of a rotary brush adapted to sweep the entire width of the cartrack and journaled belowsaid car-base diagonally of the car, the outer periphery of said brush lying in the same Vertical plane with the diagonal end of the car-body, and means for driving said brush, substantially as de scribed.

2. In a sweeper-car, the combination with a car-base, of hangers secured to the opposite sides of the bottom of the car, each consisting of a bracket and a link removably bolted at its upper and lower ends to the bracket, the adjacent faces of the bracket and link being curved on the arc of a circle to form a segmental slot, bearings vertically movable in said slots, a brush-shaft journaled in said bearings, means for raising and lowering the bearings, and means for driving the brushshaft, substantially as described.
