SPECIFICATION f; ning part of Letters Patent No. 7 00,900, dated May 27, 1902.

Application filed January 6, 1902.

To aZZ whom it may concern.-

Be it known that I, SOLOMON CONRATH, a citizen of the United States, residing at Cookport, in the county of Indiana and State of Pennsylvania, have invented certain new and useful ImprovementsinStreet-Sweepers; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to certain new and useful improvements in street-sweepers.

The object of the invention is to provide a machine of this character which shall be simple of construction, comparatively inexpensive of production and eflicient in operation, and one in which the sweepings are automatically deposited into a receptacle and the sweeping mechanism mounted so as to be readily and conveniently thrown into and out of operative position at will.

\rVith this and other objects in view, which will readily appear as the nature of the invention is better understood, the same consists in certain novel features of construction and combination and arrangement of parts, as will be hereinafter more fully described, defined in the appended claim, and illustrated in the accompanying drawings, in which- Figure 1 is a View looking toward one side of a street-sweeper embodying my invention. Fig. 2 is a View looking toward the opposite side thereof. Fig. 3 is a top plan view of the machine. Fig. l is a top plan view of the rear axle and wheels, showing a modification in the gearing.

' Like reference characters designate like parts throughout the several views.

The numeral 1 in the drawings represents an ordinary wagon box or body which serves as a receptacle for the sweepings. This box or body is supported by the front and rear wheels 2 and 3, mounted upon the axles a and 5. These parts of the running-gear may be of the ordinary construction, except that I fix upon the hub of one of the rear wheels 3 a spur gear-rim 6 and upon the hub of the other rear wheel 3 a sprocketrim 7. WVhere the axle 5 rotates and the wheels 3 are fixed there- Serial No 88,662. (No model.)

to the said gear-rims 6 and 7 may be secured to or formed upon the axle, if desired, as shown in Fig. 4.

The sweeping mechanism is carried by a frame'S, mounted to swingin a vertical plane upon a transverse shaft 0, journaled upon the upper rear end of the body, said frame comprising in its construction side bars 10, connected by cross-pieces 11 and having depending therefrom hangers 12, maintained in rigid relation to the bars by inclined braces 13. The forward ends of the bars are extended to form hand-levers 14, by means of which the frame may be swung up and down on said shaft 9, and the free ends of these levers are adapted, by means of a pin 15, to be engaged by catches 15, secured to the sides of the wagon-body, to-hold the frame and the sweeping mechanism carried thereby elevated out of action.

Journaled in the lower ends of the hangers is a shaft 16, carrying the rotating brush 17, with which cooperates an endless conveyor 18, which carries the sweepings from the brush to the box or body 1. This endless conveyer is mounted upon a suitable frame 19, supported at its lower end from the hangers 12 or shaft 16 by braces 20 and mounted to swing at its upper end upon the transverse shaft 9. Motion is transmitted to the endless conveyer through a sprocket-pinion 21, fixed to the shaft 9 and connected by chains 22 to sprocket-wheels 23, fixed to a shaft journaled in the lower end of the conveyor-frame 19. The shaft 9 is provided with a sprocket-wheel 23 and is driven by a chain 24, connecting said sprocket-wheel with the sprocket wheel or rim 7 on the hub of one of the rear wheels 3.

The brush 17 is rotated by means of a sprocket-pinion 25, fixed to the shaft 16 and connected by a chain 26 with a sprocketwheel 27, suitably journaled upon the bed or body 1 and rigidly connected with a spur gear-wheel 28, which meshes with the spurgear 6, fixed upon the hub of the other rear wheel.

A curved deflector or conductor plate 29, secured to the braces 20, is provided to cover the space below the brush 17 and between the same and the lower end of the endless conveyer to catch the sweepings from the brush and permit ofthe same being forced up onto said conveyer.

In operation the sweeping mechanism is thrown into action by releasing the catches from engagement with the levers 14, whereupon the frame 8 will swing downward by gravity, thus bringing the brush 17 into contact with the ground. The rotation of said brush effects the sweeping of the street-surface,and the sweepings are deposited thereby upon the endless conveyer 18, which deposits the same into the wagon bed or body 1. The sweeping mechanism is thrown out of action by forcing "or pulling the levers 14 downward and bringing them into engagement with the catches 15, whereby the frame 8 is swung upwardly and the brush is elevated above the surface of the ground.

When the wagon-body l is filled, the sweepings may be removed therefrom in any approved manner.

From the foregoing description, taken in connection with the accompanying drawings, it is thought that the construction, mode of operation, and advantages of the invention will be readily apparent without requiring an extended explanation.

I claim In a street-sweeper, the combination with an ordinary wagon box or body and its running-gear; of a transverse shaft journaled upon the upper rear end of said box, a swinging frame independent of the wagon frame or box and comprising side bars connected by suitable cross-pieces and mounted to swing upon the transverse shaft, the rear ends of said bars projecting beyond the rear end of the Wagon-box and the front ends thereof being extended forwardly on opposite sides of the body and terminating in lever-arms,

hangers depending from the rear ends of the.

side bars, a shaft mounted in the hangers and carrying a rotatable brush, an endless conveyer-frame mounted to swing upon the transverse shaft, braces connecting the lower end of the conveyer-frame with the brush-shaft, whereby said conveyer-frame is mounted to swing with the sweeper-frame, an endless conveyer carried by the conveyer-frame, gearing between the transverse shaft and endless conveyer for operating the latter, gearing between the transverse shaft and running-gear of the vehicle and between the brush and running gear for driving said transverse shaft and brush, and catches for engaging the lever-arms when the latter are depressed to hold the swinging frame and brush mechanism elevated, substantially in the manner described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

SOLOMON CONRATI-I.
