To all whom 'i'tinay concern:

Be it known that I, Fnnnnnron EDWIN PENFOLD, a subject of the King of Great Britain,

The 1purpose of this vide aight portable of being used by a lad and invention is to pro street sweeper capable which Wlll be more s eedy, effective and cleaner in operation t an any means The essential features a light detachable dust recep hopper,

hitherto in use.

of the invention are lippeda revolving brush adapted to be tacle or moved into and out of contact with the road,

and a light frame or carriag wheels.

In order that my invention understood reference will now e mounted on may be clearly be made to the accompanying sheet of drawings in which Figure 1 1s a perspective view of the ma- Fig. 3 is chine. Fig. 2 a horizontal section of same. a perspective view of the carriage showing brush out of contact with the ground and thrown back on the handle of the carriage and the dust an remov ed. Fig. 4 is a perspective view 0' the dust pan;

In the drawings similar numerals of reference indicate similar parts in all the figures.

Referring to Figs. 1 and 2,

of the carriage of which sistsof a lipped peris adapted to the Wheels; The receptacle for hopper 8. This lipped hopfit on the axle of the carriage 5 is the handle 6 is the axle and 7 the dirt conand is provided with lugs 9, engaging there with. To insure the rigidity of the lipped hopper 8 on the carnage, a socket 10 is fastoned on the back thereof, said socket being adapted-to fit on a projecting lug 11 provided on the top of the handle 5 of'the carriage.

The horizontal brush 12 is mounted in front of the lip 13 of the hopper between a pair of shafts 14 extending one on each side of the hopper. These shafts on the axle of 14. are pivoted the carriage and integral or fastened to the ends of these two shafts is is bracket 15 is provided for a bracket 15 passing over the brush. This the purpose ofv raising the brush out of contact with the ground, also for The brush 12 is adapted to means of achain 16 gearing keeping the frame rig-id.- be revolved by with sprocket This shield 18 hingedior the puigoose of allowing it to fall back on to the hen e 29 of the hop per thereby permitting the brush to be lifted back over the hopper.

of the hopper a hinged flap 21 (see Fig. 4)}8 provided thereon and is adapted to be raised by means of a rod 22 which is passed through an OIlfiCG' in the top 1 of the hopper, thus forcing the material accumulated thereon into the back of the hopper 8.

The operation of my invention is as follows:-The brush 12 being in contact with the ground, it is revolved when the machine is propelled forward by means of the chain and gear thereby sweeping the dirt into the hopper 81 The operator occasionally pulls the rod 22 thereby forcing any dirt accumulated on the lip into the body by means of the hinged flap 21. hopper requires emptying, throws the brush back on to the handle (see Fig. 3,) wheels the machine to, the nearest dust receptacle, lifts off the hopper and empties same.

JV hat 1 claim as my invention is:
