To all 'whomitfmay concern: j

Be. itknown thamwe, .THOMAS R.. MURRAY, JAMES P. VMURRAY,and.EDWARD S. fNErLAN, citizens of the United States, .residingat New London, inthe. county .of `New ,London and State of .Connecticut,..have. invented new and useful Improvements .in Street-Cleaners, of which the following `is aspecitication.

This .invention -relates tosti-eet cleaners and one of theprincipal-.objects of theinvention -is:.-to providea simple and efficient device whereby the `dirtzmay be readily removed from the streetswthout causing any dust, such as is the case with sweepers.

A further object -of the invention is to provide a vacuum operated street: cleaning device in which the exhaust in the dustchamber is conveyed directly to a hood whichincases the suction head so that.. any dust escaping from the dust chamber will be again/taken upby the suction head and thereby prevented from escaping.

Further objects of this invention will appear as the following specific description is read in connection with the accompanying drawings which form a part of this application, and in which l Figure 1 is a side elevation. Fig. 2 is a rear elevation. Fig. 3 is a longitudinal section on the line 3-3 of Fig. 2. Fig. 4 is a front elevation partly in section. Fig. 5 is a vertical section on the line 5-5 4of Fig. l.

Referring more particularly to the drawings, 1 represents the chassis of the ordinary motor vehicle upon which is hung the engine casing 2 having projecting therefrom the driving shaft 3 which is connected to the driving wheel 4 by means of chains and sprockets 5.` The ,front wheels are steered in the usual manner from the steering post 6 and in all other respects, the parts described are similar to an ordinary motor truck. Mounted upon the chassis is a box-like body 7 which overhangs the wheels thereof and has a door 8 hinged to one side thereof so that access may be had to the dust chamber 9 for removing the dust and accumulated dirt therein. The forward portion of the body is separated from the dust compartment by 'means of a par'-l tition 10 so as to form a suction compartment 11, as shown. This compartment has arranged therein a suitable shelf 12 upon which a suction blower 13 is mounted. The

,blower 13 is preferably'driven .by `a belted .connection 14'with a counter shaft 15 driven through .themotor by abelt and ipulley 16 .and 17, the latter element. being loosely .mounted upon the counter shaftand being :connected .tothe shaft 15 by means of the clutch 18 Vcontrolled .by a-lever 19 vadjacent the .drivers seat 20.

The .blower is provided with an exhaust 21 and with an inlet pipe 22 which extends from the back of the body through the com- .,partulent 9.fto.a connection with the blower. rThe inletpipe 22 is connected toa suction .rhcad 23by.1neans of an elbow 24 anda ilexible. joint.25 .which l,pei-mits. the raising of the suction hcad,.as.will behereinafter described, so that the same may bev thrown to inoperativeposition and may also ace commodate'its'elf tov the inaccuracies in the road surfaces. l

The suction head and its associated parts are arranged within a hood 26 which consists of aplurality'of uprights 27 connected together by rectangular frames 28 and covered with any suitable fabric 29, such as canvas or the like which is attached to the separate frames in any suitable manner.

The lower frame 28 is preferably secured to f the lower end of the suction head and the upper frame is supported upon bolts 3() adjustably carried in brackets or arms 31 and having compression springs 32 surrounding the same between the frame and the bracket arms. These springs permit the raising and lowering of the hood so as to accommodate itself to the inaccuracies in the road surface and also permit the raising of the suction head 23.

At the forward end of the vehicle, there is preferably provided a fender 33 which is arranged diagonally across the vehicle'so as to force large objects to one side ofthe same and prevent engagement thereof by the hood. Adjacent the rear of the ve hicle immediately in front of the hood is a scraper 34 normally raised from the ground by means of a spring 35 and actuated by a connecting rod 36 and lever 37 so as to be brought into engagement with the road surface for loosening the dirt thereon. 4The body 7 is preferably provided with an ex. haust opening 38 which 1s controlled by a sliding screen 39 having an operating handle 40 and the hood is provided with a reg'- istering opening..` The hood 1s preferably supported upon suitable rollers 4:1, as shown. ln order to raise the hood and the suction head from the ground, there is pivoted to the front of the vehicle adjacent the drivers seat a lever 42 connected to an arm 43 on the suction head by means of a cable 44 which passes over pulleys 45 mounted upon the top of the body 7. Y

It will be seen that the suction head is yheld adjacent the rear of lthc hood so that any dirt exhausting through the screen 39 and falling in the rear of the 'suction head will be thereby picked up again and carried into the dust chamber 9. The hood is of such size and material of such quality as to permit the eXhaustromthe blower to read'- ily escape withoutplacing any strain thereon and some air is filtered through the can` vas fabric of the hood, as will be readily understood.

What is claimed is 1. yIn a street cleaner, a truck, a closed receptacle mounted thereon, a suction pump arranged to discharge in the receptacle, said receptacle having a screened exhaust opening, a suction head connected to the pump anda hood surrounding the suction head and covering the exhaust opening, means for supporting the hood upon the ground, and means to resiliently hold the same in engagement with the ground.

2. In a street cleaner,l a truck, a vclosed body mounted thereon and having an exhaust opening, a partition dividing the body into separate compartments, alsuction pump arranged in one compartment, means for driving said suction pump, a suction head connected to lthe pump, a hood surrounding and connected to the suction head, means for supporting the hood upon the ground, means for resiliently holding the hood in engagement with the ground, and means for raising the head and hood against said holding means.

In testimony whereof we alix4 oui` signatures in presence of two witnesses.
