STREET-SWEEPING APPARATUS.

SEEGIFICATION forming part of Letters Patent No. 667,132,dated January 29. 1901.

Application filed September 29, 1900. Serial No. 31,575. (No model.) A

A a citizen ofthe United States, residing at Iroquois Hotel, in the city of Toronto, in the county of York and Province of Ontario, Canada, have invented certain new and useful Improvements in Street-Sweeping Apparatus; and I hereby declare that the following is a full, clear, and exact description of the same.

This invention relates to certain new and useful improvements in that class of streetsweepers employed in sweeping and cleaning pavements, park-walks, boulevards, lawns, stables,freight-sheds,&c; and the object of the invention is to so construct the sweeper that it can be easily propelled and operated and will efficiently and expeditiously perform the duties required of it; and the invention consists, essentially, of the device hereinafter more fully set forth and more particularly pointed out in the claim.

In the drawings, Figure l is a side elevation of the street-sweeping apparatus with the parts in their operative position, showing in dotted lines the dust-receptacle in the dumping position. Fig. 2 is a side elevation from the opposite side to Fig. l, showing the parts in theirinoperative position. Fig. 3 is a plan View of the apparatus. Fig. 4 is alongitudinal view through one of the hubs. Fig. 5 is a vertical section through the same.

Like letters of reference refer to like parts throughout the specification and drawings.

a represents the axle, fitted with the usual axle-arms, to the inner ends of which are keyed circular disks b, fitted with peripheral recesses c, having inclined bottoms c. Contained in each of the recesses c is a frictionball d, the diameter of which is less than the major depth and greater than the lesser depth of the recess. Fastened to the outer side faces of the circular disks b are washers a3, each of' which partly overlaps the adjacent side face of its respective hub f, the purpose of the washers being to retain the friction balls d in their respective recesses. Mounted on each axle-arm is the hubfof a ground-Wheel e, the bore of which lits snugly the rim of the disk. The recesses are so arranged in relation to the hub and axle that during the forward rotation of the Wheels the balls will roll to the shallower end of the recesses and bind against the bore of the hub and inclined bottom, causing the united revol ution of the wheels and axle,`and during the reverse rotation of the wheels the balls roll to the deeper end of the recesses and disengage themselves from the bore of the hub, so that the ground-wheels can revolve without causing a corresponding revolution of the axle.

Connected to lthe axle a are two rearwardlydirected arms g, one contiguous to each of the ground-Wheels c. Journaled in the outer ends ofthe arms g is the shaft hof the brush 'L'. The brush i can be made of any suitable size and material. It is preferable, however, to make the brush of steel bristles, as it has been found in practice that they are more durable and perform their work more effectively than any other style at present in use.

Keyed on the axle at is a spur-wheelj, which meshes with a spur-wheel lc, loosely mounted on a stud l, projecting outwardly from the side face of the adjacent arm g. Connected to the side face of the spur-wheel la is a sprocket-wheel m, and mounted on the adjacent end of the shaft h is a sprocket-Wheel n. Passing around the sprocket-wheels m and n is a sprocket-chain 0, by means of which motion is transmitted from the sprocket-wheel m to the shaft h.

Connected to the axle aintermediate the arms g are the handles p, by means of which the sweeper is propelled and operated. Rigidly connected to each handle p is a brace q. Formed in the lower end of each brace q is a slot fr, and extending outwardly from each arm g is a pin s, which projects through the respective slot in the adjacent brace q. By means of the braces and pins the brush is steadied during its operation and by means of the slots r it is permitted to move vertically to adapt itself to the inequalities of the surface over which it is sweeping.

During the forward revolution of the,

is transmitted by the sprocket chain to the sprocket-wheel n and shaft h of the brush t. The brush t during its revolution sweeps the IOO particles of dust, the., in advance of the machine.

Looselysuspended from the axle ais a dustreceptacle t, having an open back u opposed to the brush z'. The bottom of the dust-receptacle t clears the pavement over which the apparatus is moving and is sufficiently close to the same to enable the brush to sweep the dirt, the., from the pavement into it. Connected tothe top of the dust-receptacle is an outwardly -directed arm e, to which is connected one end of a link w,-the opposite end ol the link w being connected to a crank y. By drawing the link w toward the ends of the handles p the dust-receptacle can be raised into the position indicated in dotted lines in Fig. 1 of the drawings in order that it can dump its contents when it is desired to do so, so that the contents can be placed in a receptacle or in a wagon to be carted away.

When the apparatus is moving over a pavement or surface which is not required to be swept, the parts can be tilted into the position shown in Fig. 2 of the drawings, which simply consists of turning the handles@ in the direction indicated by arrows in Fig. l.

This has the effect of reversing the revolufor the operator of the apparatus when going to or from work to use the dust-receptacle for the purpose of carrying his coat or other parcels.

When lthe apparatus is notin use, it can be set in such a position that the handles will be practically perpendicular, in which position it will occu py but a comparatively small space. The dust-receptacle is of such a shape that-it will securely hold all dirt, the., that is swept into it, and by means of the lever the receptacle can be dumped whenever it is fully or partially charged, as determined by the operator.

Having thus fullydescribed my invention, what I claim as new, and desire to secure by Letters Patent, is-

A street-sweeperembracing in ils construction an axle, ground-wheels mounted on the axle, a friction-clutch interposed between Ithe axle and ground-wheels to cause their unitedv rotation during thc forward revolution of the ground wheels, rearwardly directed arms connected to the axle, a brush journaled in the rearwardly-directed arms, a dust-receptacle suspended from the axle the opening of which is opposed to the brush, a spur-wheel mounted on the axle, a spur-wheel mounted on a stud intel-meshing with the spur-wheel on the axle, a sprocket-wheel connected to the spur-Wheel on the stud, a sprocket-wheel mounted upon the shaft of the brush, a sprocket-chain passing around the sprocketwheels, handles connected to the axle, an arm connected to the dust-receptacle, a dumpinglink one end of which is pivoted to the arm and the other end connected to a crank pivoted to one of the handles substantially as specified.
