(4.) In a road-cleaning machine, the combination of two sets of rotating arms carrying cleaning-brushes, the arms in each set being pivoted upon a separate sleeve journaled upon a fixed vertical pillar, a bevel wheel upon one sleeve gearing with a similar wheel upon one end of a spindle which has a bevel wheel upon its opposite end gearing with a similar wheel upon the other sleeve, a main-axle of the machine revolved by forward motion of the travelling-wheels, a bevel driving-wheel free upon said axle, and a clutch by which it may be caused to revolve therewith, means for operating said clutch by a hand-lever, a bevel pinion in gear with the bevel driving-wheel and fixed upon a spindle the opposite end of which has a bevel wheel in gear with the bevel wheel upon one of said sleeves, substantially as and for the purposes described and illustrated. (5.) In a road-cleaning machine, the combination of rotating arms carrying cleaning-brushes and pivoted at their ends upon a sleeve, means for revolving said sleeve upon a fixed support by forward movement of the travelling-wheels of the machine, an inclined cam-race beneath the arms, an inclined shute up which the material is conveyed by said brushes, and a hopper receiving the material from the shute or elevator consisting of buckets carried upon endless sprocket-chains for removing the material from said hopper, and means for actuating said elevator from the travelling-wheel axle, substantially as described and illustrated. (6.) In a road-cleaning machine, the combination of rotating arms carrying cleaning-brushes and pivoted at their ends upon a sleeve, said sleeve being supported upon a pillar fixed to the frame of the machine, a bevel wheel upon said sleeve gearing with another bevel wheel upon a spindle which has a bevel pinion upon its opposite end driven by a bevel wheel upon the axle of the travelling-wheels of the machine, substantially as described and illustrated. (7.) The combination in road-cleaning machinery of two corresponding sets of rotating arms carrying cleaning-brushes, the members of each set of arms being pivoted upon a sleeve revolvable upon a fixed support, a bevel wheel upon one sleeve gearing with a bevel wheel fixed upon a spindle which has another bevel wheel at its opposite end gearing with a bevel wheel upon the sleeve which carries the other set of arms, with means for rotating one set of arms by forward motion of the machine, substantially as and for the purposes specified and illustrated. (8.) In a road-cleaning machine, the combination of rotating arms carrying cleaning-brushes and pivoted at their ends upon a sleeve, means for revolving said sleeve upon a fixed support by forward movement of the travelling-wheels of the machine, an inclined shute up which material is conveyed by said brushes, a hopper receiving material from the shute, and an inclined circular cam-race beneath said arms, said cam-race being in two parts, the one fixed and the other pivoted, with means for operating said pivoted portion of the race whereby it is raised with the arms resting upon it, substantially as and for the purposes described and illustrated. (9.) In a road-cleaning machine, rotating arms carrying brushes and pivoted at their ends, a cam-race beneath said arms whereby they are caused to rise in one portion of their path of rotation, said cam-race being in two parts, the one fixed and the other pivoted, a hinged inclined shute up which material is conveyed by the brushes, a rocking shaft having a lever-arm projecting beneath said shute and a lever-arm projecting beneath the pivoted portion of the cam-race, with means for rocking said rocking shaft and thereby simultaneously lifting the pivoted part of the cam-race and raising the lower edge of the shute, substantially as and for the purposes described and illustrated. (10.) In a road-cleaning machine, a main axle of the machine revolved by forward motion of the travelling-wheels thereon, a bevel driving wheel free upon said axle giving motion through bevel gearing to rotating arms carrying cleaning-brushes, a sprocket chain-wheel by which motion is conveyed to an elevator, said chain-wheel being free upon said axle and connected to said bevel driving-wheel, a sliding clutch upon said axle by which the bevel driving-wheel and chain-wheel may be caused to revolve therewith, a fork working in a recess in said clutch, a rocking shaft to which said fork is attached, and a lever for operating said rocking shaft, substantially as and for the purposes specified and illustrated. (11.) In a machine for cleaning roads, the means of attaching a cleaning-brush to an arm consisting in forming a recess in the brush which receives a carrier-bracket one end of which is hooked and takes into a hole in the end of the arm and the other terminates in a lug wherein is formed a slot receiving a bolt which also passes through a hole in the arm and is provided with a wing nut, substantially as specified and illustrated. (12.) The improved machine for cleaning roads consisting of the parts arranged, combined, and operating substantially as and for the purposes described and illustrated.
