and operated by the motor of the motorc cle, and' 10 a rubbish receiving means .for ebris swept up by the member or brush 9.

In the present embodiment of the invention, the motorcycle 7 includes a single rear wheel 1.1 mounted upon an axle 12 and front wheels 13 and 14 mounted on an axle 15. said front wheels being steered by mecha nism 15.A

The frame 8 comprises substantially parallel and horizontal bars 16 and 17 which are mounted on opposite 'sides of the motorcycle and secured to the axle 12 intermediate their ends near the rear ends thereof by Ushaped brackets 18 so as to be spaced from the sides of the motorcycle. The bars 16 and 17 extend beyond the'ends of the motorcycle and from' a point near the front wheels 13 and 14 extend upwardly and forwardly, theaxle 15 acting as a support for the bars. Hinged to the forward ends of bars 16 and 17` as at 17 is a pair of parallel arms 19which will be later more fully described.

The bars 16 and 17 comprise the main sta- -tionary framel anda brush supporting frame consisting of horizontal parallel bars 20 and 21, is plvotallv connected to the bars 16 and '17` as at 22. The forward ends of the bars 2O and 21 are connected with one another by a bar 23 and depending from saidbar are brush-supporting arms 24 between andV upon which is journaled a shaft 25 for the brush 9. A sprocket wheel 26 is carried by the brush 9 and has mounted thereon a chain 27. 28 fixed to a shaft 29 located between the. arms 24 above the brush. The shaft 29 is driven by a belt 30 which is rovearound a. pullev 31y carried bv the motor shaft 31" of the motorcycle 7 and a pulley 31a on the shaft 29. The pullev31 is loosely mounted upon the shaft 31b driven bv the motorcycle 7. This pulley is also provided upon one side face with a clutch member 31. and a clutch member 31?l is splined upon the shaft and adapted for coiiperation with the clutch member 31. vClutch shifting lever 31 is provided to move the clutch member 31d into and out of operative position.

Hinged as at 32 to the forward end of the brush supporting frame comprising the bars 20, 21 and 23, is a dust hood 33 which in- This chain coperates with a sprocket cludes a top 'plate 34 and depending end 0 pivoted a rod 58 also connected with the 9 and chamber 10. A guardfpl'ats `llliis secured to the arms 24 and extends downwardly and rearwardly from said armsr over the brush 9. This plate prevents debris imm being thrown rearwardly by the brush during the operation thereof.`

Pivoted uponthe bar 16 of the main frame is a bell crank 36 which isconnected at one end to the bar EZilby` a ylink 37. A' lever 938 is pivoted as at 39 upon said bar 16 ata point y near thej rear end thereof and connected with the lever and "bell crank'is a rod 40., The lever 38 is provided with locking mechanism 41 whichcoperates with a notched quadrant 42 fixed to the bar 16. It will be seen that `when the lever 38 is'moved rearwardly, a pull will be communicated to the bell crank 36 throughthe rod 40, and the frame comprising the bars and 21y and which .supports the brush 9 and hood 33 willfbe llfted upwardly, causing the brush to be spaced from the surface which is to be swe t.

at one end and is connected to an upstanding ear 45 carried on the hood`33 by a link 46. Alever 47 similar to the one 38 and cooperating with the quadrant 42, is pivoted y'upon the same pivot for the lever" 38 and is connected with the arm 43 by a rod 48. When this lever is moved rearwardly, thel hood 33 is lifted upwardly so that the top plate 34 thereof is moved from overlying relation to the chamber `10.

Vend of the arms 19 and rotatabl supports the chamber 10. An adj ustab e bracing means 49'l is carried` on top of the frame 4 The `-ichamber 10 is preferably cylindrical and is provided with a longitudinal opening 50 in one side thereof, ythe ends of the chamber bein closed. Projecting from one lon` gitudina .edge of the opening 50 is a guard Itudnal edge with a flexible strip plate 51 extending the full length of the chamber`10 and provided at its free longi- 52 designed to contact with the surface eing" swept. This plate 51 serves to guide the debris swept by the brush into the chamber 10 through the opening 50 and acts as an ordinary dust pan. A similar smaller plate or a flange 51iis provided on the ,corresponding edge of the open'- ing 50. A sprocket wheel53 is iixed to the chamber 10 for rotation therewith and co operates with a larger sprocket 54 mounted upon one of the vertical bars of the frame 49.

A chain 55,is mounted upon the sprockets 53 and 54.v A crank arm 56 is ixed'to the sprocket 54. Pivoted upon the forwardend of the brush 4supporting frame is a rocker member 57 to the upper end of which is crank arm 56. f A lever 59 is pivotedupon i ythe bar 16 upon the pivots for the levers 38 and 47. A rod 60 connects the lever 59 with the member?. It will be seen that when cycle so tat the rubbish swept up by the brushand after having been dischar ed from the chamber 10 may e placed wit the receptacle. This recetacle is preferabl tangular and is rigi ported upon the bars 16 and 17 alsoupon a rod 63 which connects the rear ends of the bars with each other. An elongated openingy or recess 64 is formed in the receptacle to receive the wheel 11 and the rear end wall of "the receptacle is hinged as at 65. Suitable s rin catches 66 hold the hinged wall in, c ose position.l A lid.not shown may be provided for the receptacle if desired.

Carried' at the lower ends of the frame 49 are rollers66 which extend below the cham- An arm'43 is pivoted as at 44 to t e bar 16 ber 10 and are, normally spaced from the ground.

These rollers are adapted to encounter the ground or pavement when the machine oplyfastened to an supf crates upon' rough surfaces and prevent the f `chamber 10 from` bumping or scraping the ground. "Should the rollers encounter the ground or a bump the whole frame 49 inclu'ding the chamber 10 and arms 19 moves upwardly,y the hinged arms 19 permitting this action.

In operation, the motorcycle, is run in the ordina manner and theoperator by manipulating thelevers 38, 47 and 59may set the sweeping apparatus at the properposi- `tion for sweeping. Assuming that the mechanism is in the position shown in Figs.

1y and 3, the brush 9 will be rotated in a counter-clockwise direction throughthe pulley 31, belt 30, pulley 31, sprocket28, belt 27 and sprocket 29. Rubbish swept up by the brushwill enter the chamber 10 through the opening 50 and the plates 57 and 57' together with the flexible strip- 52 thereof l Aprevent the brush from throwing the debris ahead of the machine. The'hood 33 in covering the space between the brush andopen side of thememberlO prevents thedust and debris from being scattered. By adjusting the lever`38, the brush E) may be moved into the desired relation to the surface to be swept so that a light or full sweeping action mav be had as'desired.

When it is desired to dump the rubbish yfrom 'the member 10, the lever 47 is pulled rearwardly, causing the hood 33 to be lifted into the position shown 'inf Fig. 4 of the drawing# lVhen the hood is'in this position, the member 10 is free to be rotated and a rearward movement ofthe lever 59 causes f l dumped and picked up and Aplaced withinl the receptacle 62 by the operator of the machine. The entire sweepingx apparatus may be lifted from contact wit t e ground by pulling the lever 47 to the position shown in ig. vof-the drawings. This lifts the frame comprisin the bars 20 and 23 and the brush 9 carried y the frame, allowin the motorcycle to move freely and in t e ordinary manner. l

With reference to theforegoing descri tion and accompanyin drawings, it will. seen that we haveprovlded a street sweeplnr machine which may be easily handle throughout congested trailic districts in cities and will o crate effectively to sweep up 'rubbish and t e like from the streets 1n an expeditious manner.
