Application filed November 25, 1907. Serial No. 403,825.

To all 107mm it may concern:

Be it known that I, SOLOMON CONRATH,.& citizen of the United States, residing at Olean, in the county of Cattaraugus and State of New York, have invented certain newand useful Improvements in Street- Swecpcrs; and I do declare the following to be a full, clear, and eKact description of the invention, such as will enable others skilled in the art to wnich it appertains to make and Fig. 2 is a right hand side elevation.

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 recci itacle for the sweepings. This box or body is supported by the front and rear wheels 2 and 25, mounted upon the axles 4 and 5. 'lhesc parts of the running-gear may be of the ordinary construct-ion, cxcept that I fin 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. wheels 3 are fixed thereto the said gearrims 6 and '7 may bc secured to or formed upon the axle, if desired.

The swooping mechanism is carried by a frame 53, mounted to swing in a vertical plane upon a transverse shaft 9, ournalcd in standards 9 mounted upon the 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 levers, 14, upon which are secured rack bars, 29, and these lovers are adapted, by means of a pin 15, to be cn-gagcd by catches, 15, secured to the sides of the wagon-body, to hold the Where the axle 5 rotates and the frame and the sweeping mechanism carried thereby elevated out of action.

Secured to the body of the wagon on each side thereof are bearing blocks. 3,0, in which is journaled a transverse shaft, 31, provided with wheels, 32, at each side to engage the rack bars carried upon the ends of the levers 14. One end oflhe shaft is suitably squared to receive an operating wrench by which. the frame may be tilted upon its fulcrum or shaft, 0, and the sweeping brush thereby adjusted. When it is desired to raise the brush entirely out of engagement with the ground, the shaft is turned until the gears 32 discngz'tge themselves from'thc racks 20 and the dcviceis then thrown down by hand until the hooks 15 engage over the pins 15. 1

Journalcd 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 swccpings from the brush tothe box or body 1. This endless conveyor is mounted upon a suitable frame, 19, supported at its hangers 12 or shaft 16 by braces 20 and mounted to swing at its upper end upon the ransvcrs'e shaft Motion is transmitted to the endless conveyor through a sprocketpinion 21, fixed to the shaft 0 and connected by a chain 22 to the sprockctswhocl 23%, fixed to a shaft ,journalml in thclourr end of the. conveyor frame 10. The shaft 0 is provided with a sprocket wheel 23 and is driven by a ower end from the chairf 24, connecting said sprocket wheel with tho 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 lo the shaft 16 and connected by a chain 24; wheel 27, suitably journalcd upon the bed or body 1 and rigidly connected withv a spur gear-whecl 28, whi l) meshes with the spurgear 6, fixed upon the hub of the other rear wheel.

A curved deflector or conductor late 29', secured to the braces 20 is provider uncover the space below the brush 17 and between the. same and the lower end of the endless convcyer to catchv the sweepings from the brush and permit of the same being forced up onto said conveyer.

In operation the swee ing mechanism is thrown into" action by re easing the catches 15 from engagement with .the lovers I4,

with a sprocket 5 tion of said brush eflects the sweeping of the street surface, and the sweepmgs are dewhereuponthe frame 8 will swing down' wardly by gravity, thus bringing the brush 17 into contact with the ground. The rota- I claim as new, and desire to secure hyLettors-Patent, is:

In a street sweeper, the Combination of a wagon body or box and its running gear, standards mounted upon the rear end of the body, a sweeper mechanism support pix otod upon said standards, a sweeper mechanism carried thereby, a pair of rigid forwardly ex- 1 tending arms forming a part of said support, i

a pair of segmental rack arms connected to 1 said ar ns a pair of bearing elements secured l to-the wagon body, a transverse shaft j0urnaled in said hearings on top of the wagon body adjacent its forward end, a pair of gears rigidly connected to said shaft at each end thereof on the outside of said bearings and adapted to engage said rack arms, an

operating lever pivoted to said shaft at one end thereof, a pawl pivoted on said lever for engaging the gear to operate the same in one direction only, a pair of pawls pivoted one to each bearing element and adapted to'hold the gears in adjusted position, pins onsaid arms, and'hooks pivoted to the body for enga 'ing said pins whereby the arms may be he (1 in depressed position and the sweeper mechanism elevated.

In testimony whereof I have hereunto set my hand in presence of two subscribing withis SOLOMON CONRATHL mark l/Vitnesses:

HENRY EvENs, V EVA M. EVENS.
