STREET-SWEEPER.

SPECIFICATION forming part of Letters Patent No. 593,086, dated November 2, 1897. Application filed December 7, 1896. Serial No. 614,?57. (No model.)

work cleaning up the streets, taking the place of theordinary hand brooms and sweepers. The sweeper is also adapted to be built on a large scale.

Reference is to be had to the accompanying drawings, forming a part of this specification in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a side elevation of my device. Fig. 2 is a plan view. Fig. 3 is a rear end elevation, and Fig. l is a longitudinal sectional elevation on line X X of Fig. 2.

My invention consists, essentially, of a box or receptacle for the sweepings supported upon wheels and having pivoted thereto a hopper so placed as to receive the sweepings from a rotary broom. The sweepings are directed into the hopper by means of a chute which projects under the brush and guides the sweepings into the hopper. The receptacle is open at the upper corner adjacent to the hopper-pivot, and the contents of the hopper are dumped into the receptacle by swing ing the hopper up, so as to fill this opening.

The receptacle for carrying the sweepings is represented by A and is shown as a metal box in general of a rectangular shape. The upper corner, which is at the right in the drawings and is the rear of the box as it would be operated, is left open, as shown at A. Upon the box A, at the lower edge of this opening, is pivoted at G the hopper O, which is made in general shape like the corner of the box-that is, the ends are of a substantially triangular shape and the bot tom and one side are at right angles. At the rear corner the bottom is turned up slightly, as shown at 0 thus departing slightly from an exact triangular section.

The framework F, which is attached to the box A, is carried to the rear and incloses the hopper G and the rotary brush G. This rear part of the frame is strengthened by the braces f. An axle b extends through the box A, and on each side of the box are fixed wheels B, which carry the weight of the box and its contents. One of these wheels has projections B, carrying upon their outer ends a sprocket-wheel B a sprocket-chain D passing over this wheel and to the rear and passing about a small sprocket-pinion E, which has attached thereto a gear-wheel E, meshing with a gear-wheel E upon the shaft of the rotary brush G.

Upon the frame, just in front of the rotary brush, is a scoop I, which is pivoted to the frame at I, so that the rear edge 11 thereof may drop upon the surface of the pavement just in front of the point where the rotary brush is sweeping the pavement. This scoop is contracted somewhat toward the front and serves to guide the sweepings into the hopper C.

The rear end of the frame F is supported upon a roller II, which is adjustable in a slot in its standard by means of a bolt It. By this means the brush may be adjustable ver tically to compensate for wear. By reason of the pivoting of the scoop I it may automatically adjust itself to inequalities of the street surface and to the wear of the brush. A handle F for the frame F is supported by bars f and f conveniently for a man to push the same or to control it if drawn bya horse.

The upper edge C of the hopper C is car ried above the pivot C". This pivot is placed a little to one side of the rear edge of the hopper, and as a consequence the projecting portion 0 extends over the space between the hopper and the receptacle before the hopper is in position for its contents to be dumped. In consequence of this none of the sweepings can fall between the hopper and the receptacle. This projecting portion C may be a continuation of the side plate of the hopper O or an additional plate fastened thereto, as shown in the drawings.

The hopper G is to be made of such a size and pivoted at such a point that when it is turned to its extreme upper position it will exactly fill the corner of the box or receptacle which is left open at A. In this case the corner O of the hopper will fit against the edge a of the bin or receptacle. This position is shown by dotted lines in Fig. 4. In this way the bin or receptacle A is rendered entirely inclose'd at the time the sweepings are dumped out of the hopper O. The bin may be left closed for a moment after the hopper has been dumped in order to prevent the dust from being blown out. At thelower corner of the bin a door a is pivoted, so that the bin may be readily emptied.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. In a street-sweeper, the combination of a sweepings-receptacle having the upper half of one end and an adjacent portion of the top open, a hopper pivoted at the bottom of said opening and adapted when turned up to entirely close said opening, with a supportingframe and a rotatable brush adapted to sweep dirt from the street into said hopper, substantially as described.

2. In a street-sweeper, the combination of a supporting-frame, a sweepings-receptacle having the upper half of one end and an adjacent portion'of the top open, a hopper pivoted at the bottom of said opening and adapted when turned up to entirely close said opening, and means for sweeping dirt from the street into said hopper when in its lower position, substantially as described.

3. In a street-sweeper, the combination of a sweepings-receptacle having the upper half of one end and an adjacent portion of the top open, a hopper pivoted at the bottom of said opening and adapted when turned up to entirely close said opening, with a supportingframe, a rotatable brush, and a sloping guidechute projecting under the brush. and discharging into the hopper when in its lowered position, substantially as described.

4. In a street-sweeper, the combination of a supporting-frame, a receptacle having an opening in one side, a hopper pivoted thereto near the lower edge of said opening, and having a projecting plate adapted to swing into said opening when the hopper is turned up, so as to cover the space between the two before the material is dumped, and means for sweeping dirt into said hopper, substantially as described.

5. In a streetsweeper, the combination of a supporting-frame, a sweepings-receptacle having an opening in one side, wheels for carrying the same, with a hopper pivoted at the lower edge of the opening in the receptacle and adapted to be swung up into said hole to dump its contents, a rotatable brush turned by gearing from the supportingwheels, and a pivoted guide extending under the brush and conducting the sweepings into the hopper, substantially as described.

6. In a street-sweeper, the combination with supporting-wheels, and a receptacle mounted on the axle thereof and having an opening in its rear portion, of a frame secured to the receptacle and projecting rearwardly, a wheel for supporting the rear end of the frame, a brush mounted in the frame, means for operating the brush from one of the said wheels, a scoop secured to the frame in front of the brush, and a pivoted hopper for receiving the sweepings from the scoop, said hopper being adapted to be swung to discharge its contents into the receptacle, substantially as described.

7. In a street-sweeper, the combination with supporting-wheels, and a receptacle mounted on the axle thereof, and having an opening in its upper rear corner, of a frame secured to the receptacle and extending rearwardly, an adjustable wheel supporting the rear end of the frame, a brush mounted in the frame, means for operating the brush from one of the said wheels, a scoop pivoted to the frame in front of the brush, and a hopper pivoted to the receptacle and adapted to be swung to discharge its contents into the receptacle and when so swung to close the receptacle, substantially as herein shown and described.
