EMMA V. FRENCH, OF HOOPESTON, ILLINOIS.

STREET-SWEEPER.

To all 107mm it may concern:

Be it known that I, EMMA V. Fnnzvorr, a citizen of the United States, residing at Hoopeston, in the county of Vermilion and State of Illinois, have invented new and useful Improvements in Street-Sweepers, of which the following is a specification.

The object of the invention is to provide a device carried on an autovehicle chassis by means of which it is operated for the purpose of sweeping the street and depositing the results of the sweepings in a suit able receptacle carried by the chassis. The receptacle is susceptible of being handled by an operator for the purpose of adjusting it with reference to the ground or pavement over which the device may be moved andthis means of adjustment also serves to position the brushing medium as desired with respect to the ground. Aside from this adjustment which is handled by the operator, means is provided for adjusting the brushing member relative to. the receptacle.

A further object of the invention is to provide an automobile street sweeper which is simple in construction, durable and effective in operation and inexpensive tomanufact-ure.

Other and further objects appear in the following description wherein the invention is set forth in detail.

To the exact construction in which it is shown and described the invention is not to be restricted. The right is reserved to make such changes or alterations as the actual reduction to practice may suggest, in so far as such changes or alterations are compatible in spirit with the annexed claim.

The same numerals of reference designate the same parts throughout the several figures of the drawing, wherein:

Figure 1 is a top plan view of an auto vehicle street sweeper constructed in accord ance with the invention,

Fig. 2 is a side elevational view of the sweeper apparatus per 86.

Fig. 3 is a perspective view of the receptacle forming part of the invention.

As shown, the invention is a street sweeping apparatus designed for mounting on an antovehicle chassis as that indicated in the drawings and designated by the numeral 1, this chassis having the usual traction wheels 2. On the rear axle of the chassis there are mounted the brace bars 3, one on each side of the chassis but positioned on the inner Specification of Letters Patent. Pgttgn'fgd 131 15, 1Q21,

side of the side rails thereof and supported,

ratus. This sweeping or cleaningapparatuscomprises a receptacle 5 which is closed on all sides but the front side. he bottom of the receptacle of greater width than the top and the end plates or walls of the receptacle, therefore, have their forward edges diagonally disposed, as clearly shown in Figs. 2 and 3 of the drawings. The receptacle 5 is swung from the studs 4 carried by the bars 3 and to this end hinge elements 6 are provided and attached to thereceptacle on top adjacent the rear edge thereof, these hinge elements engaging the studs and thus providing for pivotal movement of the receptacle with reference to the chassis.

In order that the receptacle may be raised and lowered as desired by an operator who will sit in the seat '1' indicated in dotted lines in Fig. 1 there is provided a hand operated lever 8 which is pivotally mounted on the chassis frame, this hand lever bein provided with a spring latch 9 engageable with any one of the teeth of the sector 10 also mounted on the frame with its arcuate portion concentric with the pivot point of the lever as is common practice in such construction. The lever 8 has connected with it an arm 11, the end of which pivotally connects with one end of a connecting rod 12 whose remaining end pivotally connects with an car 13 attached on top of the receptacle adjacent the forward end at one side of the latter. Obviously the operation of the lever S will serve to raise or lower the forward end of the receptacle, the studs 4 acting as the pivot points of movement of the receptacle in this raising and lowering operation.

Rollers 14 are attached to the receptacle at opposite ends and approximately at points falling within the center line of the bottom of the receptacle. These rollers'are designed to engage the ground or pavement when the receptacle is in operative position-that is, when it is in position to receive the refuse accumulated by the brush which forms part of the invention.

On opposite ends of the receptacle there are provided arms or bars 15 which are 5 pivoted, as indicated at 16, to the end plates of the receptacle adjacent the rear side thereof. These arms extend forwardly and support between them a cylindrical brush 17 which stands normally before the front open side of the receptacle. Adj accnt the forward side but formed in the end plates of the receptacle there are the perforations or eyes 18, each plate having aset of these eyes formed in an arc whose center is the center of the pivot point 16. Bolts 19 pass transversely through the arms and may be engaged in any one of the series of holes 18, so that the brush may be raised or lowered with reference to the receptacle. Thus if 20 the bristles on a brush wear, it may be lowered and still have the same relative position with respect to the receptacle that it had when. new. i 1

The crush 18 is designed to be rotated by one of the traction wheels 2 and to this end is equipped with a sprocket E20 over which a chain 21 is trained, the chain 21 also being trained over a sprocket 22 which is mounted on a supplemental shaft 28, this shaft ineluding a universal joint 2%, so that the two partsof the shaft may be journaled in the bearings 25 and 26 mounted on top of the U receptacle but disposed with their in different planes, so that that section of the shaft which is carried in the bearing 26 carrles a sprocket wheel 27, while one of the traction wheels 2 carries a sprocket wheel 28, a chain 29 operatively connecting these two sprocket wheels. Obviously the rotation of the tr'action'wheels will impart a 40 rotary motion to the supplemental shaft 23 and this motion will be transmitted to the brush which wiping upon a street or pavement will sweep the refuse gathered into the receptacle.

The hand lever 8 provides means for raising the brush to lift it out'of engagement with the street or pavement and the receptacle thereby is elevated at its forwarder open side so that it may retain therein the refuse which was gathered when the'brush was engaging the ground.

The invention having been described, what is claimed as new and useful is:

In a machine of the kind described, the

formed in tl e ends adjacent the open side bolts passing through the arms and attachable in any of the holes of the series,whereby the brush may be raised or lowered with reference to the receptacle, means fo rotating the brush, and means for raising and lowering the forward end of the receptacle.

In testimony whereof IafiiX my signature.
