STREET-SWEEPER.

SPECIFICATION forming part of Letters Patent No. 663,? 58, dated December 1 1, 1900.

Application filed June 28, 1900. Serial No. 21,958. \NO model.)

To all whom it may concern:

Be it known that I, WILLIAM HIGHT, a citizen of the United States, residing at Macon, in the county of Macon and State of Illinois, have invented certain new and useful Improvements in Street-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, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in street-sweepers, and especially to a sweeper which is adapted to be connected to the rear end of a wagon and provided with the usual elevator and rotary brush whereby foreign matter is swept into a receptacle and carried by endless conveyers to and dumped into a hopper or receptacle, from which it is carried to and emptied into a wagon-box, suitable means being provided whereby the rear end of the framework carrying the brush may be held at different.

heights and the brush raised from contact with the ground.

The invention relates, further, to the provision of a street-sweeper in which a truck adapted to be connected to the rear end of the wagon is provided with a rotary brush and suitable elevators and has secured to the inner end of said truck a rod-and-lever connection withthe rear end of the wagon-box, whereby as said lever and rods are actuated the forward end of the truck may be raised or lowered and the rear end raised, so that the brush will be held from contact with the ground.

My invention will behereinafter more fully described, and then specifically defined in the appended claims,and is clearly illustrated in the accompanying drawings which, with the letters of reference marked thereon, form part of this application, and in which drawings similar letters of reference indicate like parts throughout the several views,in which Figure 1 is a side elevation of my improved street-sweeper shown as connected to the rear end of a wagon. Fig. 2 is a vertical longitudinal sectional View through the sweeperframe and a portion of the box to which the frame is connected. Fig. 3 isa top plan view of the sweeper. Fig. 4 is a vertical sectional View through the receptacle into which the foreign matter is deposited from the brush, showing the endless conveyers therein; and Fig. 5 is a side elevation of a portion of the frame carrying the brush, showing the manner of adjustment of the rear end of the sweeper.

Reference now being had to the details of the drawings by letter, A A designate the longitudinal side beams of the truck, carrying in suitable bearings an axle B, on which the wheels O and G rotate. At the rear ends of the beams A are secured two brackets E, fastened by means of bolts or other suitable means to the under face of said beams, and each of said brackets is apertured, and a boxing E is adapted to work vertically in said apertures. These boxings (one on each side of the frame) are adjusted vertically by means of screws E and mounted in said boxiugs is a shaft F, on which are mounted the wheels G, which are connected by means of crossbeams G, which are fastened at the ends of the spokes of said wheels. These beams carry the brushes G H is a casing surrounding the rotary brush and has its lower portion upwardly bent, as at H, forming a guard to retain the foreign matter which is brushed up. On the inner curved surface of said casing and directly over said upturned portion H is a rearwardly and downwardly curved wing H against which the free ends of the brush cont-act as the brush rotates for the purpose of knocking off the foreign matter, which is allowed to fall by gravity into the receptacle beneath. Said receptacle comprises a box I, Fig. 4 of the drawings, in the walls of which are journaled shafts I, I and I on which the rollers I, I I, and l are mounted. About these rollers endless carriers 1 travel in the direction indicated by the arrows and deposit the foreign matter which is brushed up into a central trough J. Mounted on a shaft K, underneath the receptacle I,is a roller K, over which the endless carrier or elevator K travels. Mounted at an angle to the beams A A is a conveyer-trough K supported at its rear end upon the rear ends of the beams A A by means of the braces K At the upper end of said trough K is mounted ashaft K having a Wheel K mounted thereon and over which the endless conveyor K travels. It will be observed that the upper end of said trough K is downwardly disposed, as at K whereby foreign matter which is elevated therein may fall into the wagon-box underneath the outlet end of said trough.

Mounted on the shaft F is a sprocket-wheel L, and mounted in suitable hearings on the under faces of the beams A A, near their forward ends, is a shaft M, on one end of which a sprocket-wheel M is mountedwhich is connected by means of a sprocket-chain M with the sprocket-wheel L, whereby the brush may be driven. On the opposite end of the shaft M is a gear-wheel M and secured to the inner face of the wheel 0 is a gear-wheel M, which is in mesh with the wheel M whereby as the sweeper is drawn forward motion is imparted to the shaft M.

Mounted on the shaft B at any suitable location and adapted to rotate therewith is a bevel gear-wheel B, which is in mesh with a bevel-gear B mounted at the end of the shaft J which is journale'd at right angles to the shaft B in suitable bearings. The forward end of said shaft 1 carrying the pulley J has belted connection with the pulley I and by crossing said belt the two conveyers are made to travel in the opposite direction, as indicated by the arrows in Fig. 4.

The rear wheels N of the sweeper are mou nted on stub-shafts N, carried by the verticallyadjustable strips N said strips being'longitudinally slotted, as at N and held to the beams A A by means of adj usting-screws N By means of these screws it will be observed that the rear end of the sweepercarrying the rotary brush may be raised or lowered and held in an adjusted position. The forward end of the sweeper-frame is connected to the under side of the wagon-box by means-of the rod 0, which has pivotal connections with eyes 0', one on the body portion of the wagon and the other at the forwardend of the frame of the sweeper.

Mounted onthe end'of the wagon-box is a bar Q, which has a pin Q pivoted in an aperture in its upper end, said pin being fastened to the operating-lever R, which carries an adjusting-dog R, adapted to engage in the teeth of the segments, mounted on the upper edge of the wagon-box. Secured to the lower end of the box is a secondbar T, the upper end of which has pivoted in an aperture therein the pin T, which is either integral with or secured to the lever T Said lever T is pivoted at one end to the end of the Gea /5s lever B and its other end is pivoted, as at T to the upper end of the rod T, which is fixedly held to the forward end of the frame of the sweeper. By means of this lever and pivoted connections with the frame of the sweeper it will be observed that the forward end of the sweeper maybe tilted down, the frame being fulcrumed over the central axis or shaft B and the brush and the rear wheels of the sweeper may be bodily raised from the ground. The axle on which the wheels O are mounted should be so located with reference to the frame carrying the sweeper or the frame should be so weighted with reference to its fulcrumed pointon the driving-axle that the forward end of the sweeper may be easily tilted down by the application of a slight pressure.

From the foregoin'gitwill be observed that asweeper constructed in accordance with my invention may be easily adjusted and the frame so tilted that the brush may be held out of contact with theground and held in such position by means ofthe lever mechanism shown, and the apparatus may be easily adjusted to any ordinary wagon-box.

Havingthus described my invention, what Iclaimtobe new,and desire to secure by Letters Patent, is

1. A street-sweeper comprising a truck which is adap'tedto be pivotally connected to the rear end of a wagon-box, a rotary sweeper and means for operating the same, conveyers, and a pivoted lever mounted upon the rear end ofthe wagon-box", and having pivotal lever connections with a fixed portion of said truck, whereby the frame of the truck may be tilted soa's to raise the brush at" the rear end thereof from the ground, as set forth.

2. A streetsweeper comprising a truck having a rotary sweeper at one end thereof, and means for driving the same, said truck adapted to be connected to the box of a wagon, the bar secured to the rear end of the box, an operating-lever pivotally mounted on said bar,a second bar T secured to the rear end of the box of the Wagon, a'leverT pivotedto the upper end of said bar T, and a rod T fixedly held at its lower end to the truck, arid its upper end pivoted to the'lever T the inner ends of the operating lever'and lever T being pivoted together, substantially as shown and described.

In testimony whereof I aifix my signature in presence of twowitnesses.
