STREET-CLEANER.

L Specification of Letters Patent.

Patented April 3, lace.

Application filed September 6, 1902. Serial No. 122,434.

Be it known that I, JAMES GARDNER SAN- DERSON, a citizen of the United States, residing at Scranton, in thecounty of Lackawanna,

State of Pennsylvania, have invented certain" new and useful Improvements in Street-Cleaners, of which the following is a specification.

The object of this invention is to produce an improved street-sweeping machine of the motor-vehicle type in which the parts will be compactl arranged and so constructed that the vehic e may be propelled while the sweepmg and collectin mechanism is inactive, or the sweepin an collecting mechanism may be em loye while the vehicle is stationary, or bot mechanisms may be operated simultaneousl 'A further object is to provide an improved construction for conveying the sweepings from the'brush to a bag or other receptacle. With these and minor objects in view the invention consists of the parts and combinations of parts hereinafter described, and pointed out in the appended claims.

. In the drawings formingapart of this specification, Figure 1 is a top plan view of the machine with parts broken away to disclose the interior construction. Fi 2 is a vertical section on the line 2 2, Fig. 1; and Fig. 3 is an end view of the bag-filler. Fi 4 is a vertical section of the chain-casing, s owing the position of the parts therein.

e numerals indicate like parts throu h all the figures of the drawings and in t e specification.

Referrin more articularly to the drawings, l in icates the frame of the vehicle, which is mounted upon two front wheels 2, secured to the axle 3, and the steering-wheel 4, secured to the steering-fork 5, journaled in the .rear of the frame and controlled by a steering-lever 6. The frame 1 is divided into two compartments, one in the rear, as shown at 7, WhlCll the-operator occupies to control the machine and which receives the sweepings, and one in front, as shown at 8, in which is mounted the operatin mechanism. I

The vehicle is prope led by any kind of motive power; but it is preferable to mount an electric motor 9 in the compartment 8 and connect the same with the axle 3 by means of reducingearing 10. The current for the motor is obtained through wires 1 1 from cells 12, located in the lower part of the rear compartment 7, a switch 13 inthe compartment 7 controlling the current. a K

The sweeping and collecting mechanism receive their motion from a shaft 13 journaled in the front compartment 8. This shaft'lis rotated by any motive power, but referably by a motor 14, connected therewit by gearing and chain 15, and this motor receives its current from the cells 12, before mentioned,..

through wires 16 and is controlled by switch 17 ,-mounted in the rear compartment 7.

A rotary brush 118 is mounted in'advance of the vehicle and is journaled in the forward part of a collectin -casing 19. In the rear of the brush and in t e casing is mounted for receiving the sweepings from the br'usha receiving-shelf 20, the under side of which is provided with perpendicular sheet-scra ers 21, which remove any dirt not remove by brush. The receiving-shelf 20 is inclined at its forward portion, as shown at 22, and has a channel 23 at its rear. In this channel is mounted a conveyer 24, preferably a screw.

To operate the brush l8 and conveyer 24 and at the same time to permit the brush 18 and scrapers 21 to rise and fall so that an unevenness in the surface to be cleaned wi 1 not interfere with the operation of the machine, the receiving-casing 19 is swung from.

the shaft 13 by means of a chain-casmg 25 and a conveyer-casing 26. The chain-casing 25 is journaled on the shaft 13 and the shaft of the screw conveyer 24 and has mounted within it a chain 27, which communicates motion from thegear 28 on the shaft 13 to the gear 29 on the shaft of the screw conveyer 24, which shaft in turn communicates rotation through the Theconveyer-casing 26 is j ournaled at its center to the shaft 13 and at its lower end to a shaft 33 on the collecting-casing 19 and adjacent to the screw conve er 24. The conveyer-casing being j ourna ed to the frame 1 and to the collecting-casing 19, the casing is permitted to rise and fall relatively to the ame 1, and the conveyer is always in a position to convey the sweepings from the casing 19 to the frame 1, it partaking of the movement of the casing 19.

The up er end of the conveyer-casing 26 carries a ag-filling device 34. Within the conveyer-casing is mounted an endless conveyer 35 of any known variety, which passes gear 30, chain 31, and 2 gear 32 to the brush 18.

around a pinion 36 on the shaft 33 of the collecting-casing 19 and a pinion 36 on a shaft 37 in the u per part of the conveyer-casing. The ends of the shaft 37 extend beyond the sides of the casing 26 and are rovided, respectively, with pinions 38 an 39. Pinion 38 is connected, through the medium of chain 40, with a pinion 41 on the shaft v13 to com municate motion from said shaft 13 to the conveyer 35.

The ba filling device 34 consists of a horirontal to e 42 at right angles to the cnveyercasing 26, having a flared downwardly- I end t3, around which is secured a bag by an elastic band 43. This band permits, should the operator be inattentive, the bag when full to be forced off of the flared end 43, and thereby prevents the mechanism which conveys the sw-ee ings to said bag being broken, which W0 (1 be theresult if the bag were not removed; Within the tube 43 is a "screw conveyer 44, which receives motion from the pinion 39 on the shaft 37 of the conveyer-casing. I

When it is desired that no sweeping shall be done by the machine, the o erator lifts the collecting-casing by means 0 a cable 45, secured tosaid collecting-casing, passing over pulleys 46 and 17, depending into the rear compartment and having a stirrup 48, in which the operator places his foot.

A handbrake 49 on the axle 8 is provided.

and is operated by a lever 50, which connects with the band by a rod 51.

The operation of the machine is as follows: The motors bein started, motion is communicated to the an e 3, whereby the machine is propelled, and-to the shaft 13, which rotates the brush, through the medium of chains 27 and 31, in the direction of the travel of the machine, and thereby assists in its propulsion. The dirt is swept by the brush 18 into the channel 23, which it is conveyed by the screw 24: to the conveyer-casing 26, where it siaeoo struction may be made without departing from the spirit of my invention.

Having thus described the invention, the following is what i claim as new therein:

1. The combination with the frame, a shaft carried thereby, and means for rotating the shaft, of a collector-casing carrying a brush,

two casings journaled on the shaft and to the collector-casing, mechanism for operating the brush from the shaft mounted in one of the casings, and a conveyor also operated by the shaft mounted in the other casing.

2. The combination with the frame, carrying a motor, and a collector-casing carrying a brush, of two casings connecting the collector-casingwith the frame, brush-operating mechanism mounted in one of the easings, and a conveyor mounted in the other casing.

3. in a street-sweeper, the combination with the collector mounted in the front ofthe machine-frame and comprising a casing, a rotary brush journaled in the casing, a shelf mounted in the rear of the brush and a single screw conveyer carrying the material received on the shelf, to one side of the collector; of a conveyor extending from the side of the collector, a motor carried by the machine, connections between the motor, the conveyer and the brush whereby the two latter are operated by the former, and inde-.

pendent means for propelling the machine.

brush mounted in advance of the frame and movable up and down relatively thereto, a

conveyer carrying the sweepings from the brush to the rear compartment, a motor mounted in the front compartment, and pro pelling the vehicle, a second motor also mounted in the front compartment and 0 crating the conveyer and the brush in the rection of travel of the vehicle, and a cable, extending from the brush to the rear compartment b which the brush may be raised and lowere The foregoing specification signed this 4th day of September, 1902.
