Abstract: 24,918. Willis, P. R. J., [Remnsnider, G., and Hippler, F. C.]. Nov. 19. Elevatzng sweepings into receptacles ; refuse, collecting ; sweeping - machines; watering-carts.- A sweeping - machine comprises a wheeled frame 10, a side brush 26, and a rear brush 55 which sweeps the refuse to an elevator 70 delivering into a receptacle 82. A gearwheel 15 on the rear axle 13 is connected with one of the rear wheels 12 by a clutch operated from a band-lever 21 through a link 20, and arm 19, a rock-shaft 17, and a forked lever 16. The wheel 15 meshes with a wheel 24 on the end of the shaft 25 which contains a universal joint 35 and carries the side brush 26. The said end of the shaft 25 is journaled in a plate 27, Fig. 3, which is pivoted on the axle 13 and adapted to be raised and lowered to adjust the brush 26 to the slope of the road by the operation of a hand-lever 33 acting through a rock-shaft 32, an arm 31, a link 30, a bell-crank 29, and an arm 28. A U-shaped frame 36 embracing the brush 26 is connected by a link 37 to the frame 10 and is raised and lowered by a rackadjusted hand-lever 38, Figs. 4 and 5. The bolt 40 is pivoted to the frame 36 and passes through a block 42 carried on a threaded stud 43 which passes loosely through the lever 38 and is engaged by lock-nuts 44. The upper end of the bolt 40 carries lock-nuts 45 between which and the block 42 is a coiled spring 46 to allow relative movement between the brush 26 and the lever 38. A gearwheel 48 engaging with the wheel 15 is rigidly secured on a shaft 49 on which are mounted two wheels 50 from which the conveyer 70 is driven. The rear brush 55 is mounted on a shaft 54 carried by arms 56 pivoted on the shaft 49 and is driven by a chain 53 from a sprocket-wheel 51 on the shaft 49. On this shaft is also pivoted a hood 57, Fig. 2, for the brush 55. The hood carrier lugs 58 through which pass bolts 59 secured to the arms 56, each bolt carrying a spring 61 between the lug 58 and lock-nuts 60, and a second spring 62 between the arm 56 and the lug 58. The hood is raised by the operation of a hand-lever 68 acting through a connecting system of levers and bell-cranks. The conveyer 70 passes over supporting-wheels 71 in a casing 72 ; the upper end passes over wheels 80 with devices for taking up slackness in the conveyer, and the lower end passes around wheels 73 mounted between plates 74, which are pivoted to the casing 72 and attached to the hood 57 by links 76. A board 77 with stops 78 to prevent its contacting with the road is pivoted between the plates 74 to guide the refuse from the brush to the conveyer. The receptacle 82 is provided with a sloping floor, a door with a latching-device 86 and closing-handle 87, and a shoot 84. A brush 88 is adapted to bear on the brush 55 to remove adhering particles. To damp the road before sweeping, water from a tank 93 with a gauge 94 passes through a pipe 92 and a controlling-valve 91 to a series of nozzles 90 each having a separate valve. The brushes 26 and 55 are preferably of split bamboo set in wooden hoops.
