Application med April a, 1909. serial No. 487,579.

`To all whom; it may concern:

Be it known that I, OSCAR L. NEISLER, of Indianapolis, county of Marion, and State of Indiana, have invented a certain new and useful Street-Sweeper; and I'do hereby de- Clare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, in which like letters refer to like parts.

The object of this invention is to provide a satisfactory brush street clean-ing machine, one that is particularly suitable for being pushed by hand.

One feature of the invention consists in combining with a machine a removable dirtreceiving box, a brush in advance thereof adapted to engage the surface of the street, and a conveyer for conveying the dirt from the brush and discharging it into the box. When the box becomes filled it is removed and another one put in place, and the filled boxes are taken u and carried away by a wagon. Along with the foregoing lis the idea of au adjustable inclined upper front wall for the dirt box, so as to adjustit to the discharge end of the conveyer.

Another feature consists in hinging doors over the conveyer,vone above and 011e below so as to render the entire conveyer accessible if necessary.

Still another feature yconsists in the combination of a peculiar clutch mechanism on each side, one for throwing the conveyer and the other the brush into and out of operation, and a connection between said clutch means and the handles, whereby the pushing of the handles will tend to hold the clutches in engagement, while when the clutches are out of engagement the handles are turned rearwardly for use while merely `transporting the machine.

The nature of the invention will be understood from the accompanying drawings and the following description and claims.

In the drawings Figure 1 is an elevation of the left-hand side of the machine. Fig. 2 is a perspective View of the dirt box. F ig.' 3 is a central vertical section through the machine, the obscured parts being shown by dotted lines. Fig. 4 is a vertical section on the line 4 4 of Fig. 3 through a portion of the machine. Fig. 5 is a diagonal cross section through the right-hand side of the driving mechanism and frame to illustrate the clutch mechanism, the released position being shown by full lines, and the engaging position of the clutch being indicated by dotted lines. Fig. 6 is a plan view of a ortion of the side of the device shown in ig. 1. Fig. 7 is a detail of one of the handles.

A pair of suitable track wheels 10 are mounted on solid spindles 11 extending laterally from side frame bars l2, that are inclined downwardly from the rear to the front of the machine. A' U-shaped bar 13 connects said side frame bars 12 to the rear of the spindles 11, so that said U-shaped bar 13 forms part of the frame of the mawheel, there is a reinforcing segmental plate` 2() secured, and beside and outside it an arm 21 projects upwardly radially of the wheel and beyond the periphery of the wheel, and carries the rod .22 that extends across the machine above the conveyer 23. This conveyer is mounted on an actuating roll 24 at the upper end and an idle roll 124 at the lower end. The actuating roll is mounted on a shaft 25 that extends transversely of the machine and is mounted in the two side plates 26. These side plates are rigid, one on each side of the conveyer and furnish the side walls for theconveyer casing. They are bolted securely to the arms 21 by bolts 27 passing through spacers 28. The lower ends of said side bars are mounted on the lower conveyer roll 124 and are held in place by it as it extends through said side i plates 26. Said lower conveyer roll 124 is reduced at its ends, see Fig. 1, and such reduced ends have bearings in the lower part of the posts 30, which are secured at their lower ends to the front ends of the side frame bars 12, and are held in a vertical position. Hence it is observed that the side plates 26 are stationary and the conveyer moves between them. The under side of the conveyer is unprotected excepting as it rides over the inclined wall 32 of the dirt box 16, as seen in Fig. 3. There is a cover over the conveyer, the upper cover plate 34,

which at its' lower end is hinged on the rod 22, and a lower cover plate 35, which at its upper end is hinged on the same rod 22. The sides of these cover plates are turned downwardly at right angles to the body portion thereof so as to inclose the plates 26 at the sides of the conveyer. Hence access is readily made to the conveyer by opening either the top plate 34 or the bottom plate 35. The brush 41 is a cylindrical one with its shaft 42 mounted in the brush supporting bars 43. It is extended on the right-hand side of the machine'and carries a sprocket wheel 44, which is driven by the sprocket chain 45 from the large sprocket wheel 46, mounted on the sleeve 47, that is longitudinally slidable on the spindle 11, as shown in Fig. 5. The adjacent ends of the hubof the wheels 1() and 46 are toothed so as to engage and clutch each other, when the wheel 46 is moved toward the wheel l0. This clutch movement is caused by the long clutch bar 48 fulcrumed to the frame bar 12 at 49 and run through the slotted outer end of the sleeve 47, and at its upper end pivoted at 50 to the handle 51, which also at its inner end is pivoted at 52 in a recess of the side frame bar 12. When the handle 51 is in the dotted line position shown in Fig. 5, the clutches of the wheels are in their interlocking position, and when in the full line position the clutches are disengaged.

The brush supporting bars 48 have a plurality of holes 60 to receive the ends of the brush shaft 42, so that said brush may be adjustably mounted. Said bars are pivoted at 61 to the side bars 12 of the frame, and therefore the brush can ride up or down according to the surface of the street. The bars 43 extend through vertical slots in the posts 30, which guide them in their vertical movements, and they are held down by a spiral spring 62 in said posts, the tension of which is adjusted by the set screws 63. There is also a scraper 64 extending the full width of the machine, in fact, beyond the ends of the brush, which scraper rides upon the surface of the street and at its inner end is pivoted to the inner sides of the plates 26 beside the conveyer by means of pivots 65. There is a gear wheel mounted on the sleeve 47 in the left-hand side of the machine, which sleeve is mounted on the spindle 11. The adjacent hubs of the wheels 10 and 70 on the left-hand side of the machine are toothed so as to clutch-in fact, the construction and mounting of these wheels are the same at the left-hand side of the machine as at the right, which is shown in Fig. 5, and there is also on the left-hand side the same sort of clutch bar 48 arranged and operated in the same way as that shown in Fig. 5, for throwing the wheel 70 into and out of operation. The wheel 70 meshes with the spur gear 72, which is secured on the sleeve 73 mounted oh the rod 22. Said sleeve also carries a sprocket wheel 74 from which a sprocket chain 75 extends over the sprocket wheel 76 and drives the roll 24 of the conveyer and whereby the conveyer is operated. Thus it is seen that the brush actuating mechanism and the conveyer actuating mechanism are similarly thrown into and out of operation by handles 51 at the rear. The operation and construction 4are not only similar, but the operation is simultaneous. When the two handles 51 are in their inclined position, the machine is in operating condition, and when the machine is not in operating condition, the handles 51 extend rearwardly and then can be used for propelling the machine.

As the machine is pushed forward in operation the brush sweeps the dirt up on the scraper 64 and throws it on the lower end of the conveyer, which moves it up and discharges it into the dirt box. This dirt box has a sliding inclined top plate 80, see Fig. 2, the upperedge of which is adjustable with relation to the upper end of the conveyer so as to leave an opening of the right size for the discharge of dirt on the con` veyer. The plate 8O slides under the stationary top plate 32, there being space enough between said stationary -top plate and the sides of the box to permit said plate 80 to be slidable. There is a horizontal top plate 81 in the nature of a lid that is hinged at 82 so it can be turned back for discharging the contents of the box. To assist 1n manipulating the box it has a handle 83 on each side. v It can be readily lifted olf the plate 15 and also readily inserted in place on said plate 15 and between the flanges 17 and 18, whereby it is held in position.

What I claim as my invention and desire to secure by Letters Patent is:
