To all wkomz'tmay concern:

Be it known that I, CHARLES B." RepealsoN, a citizen of the United States, residing at Columbus, in the countyof Franklin and State of Qhio,-have invented a new and useful Street CleaningMachine, of which the,

following is a specification p The device forming the subjectmatter of this application is a street cleaning machine, and one object of the present invention is to provide novel means for blowing air to the rear of rotating brushesand foriapplying a suction in front of said brushes there by'to effect a thorough cleaning of the surface: over which the brushes'pass.

Another object ofthe' invention is to provide novel means for supporting :the brush casings. v v

A further ohject of the invention is to improve the suction and discharge mechanism.

The invention aims to improve thecollccting rece 'itacle and parts adjacent thereto.

It is within the province of the disclosure to improve generally and to enhance the tility of devices of that type to which the present invention appertains.

With the above and othenob iects lnvlew which will appear asthe description proceeds, the invention resides in'the combinaand claimed, it being,

tion and arrangement of parts andiin the details of. construction hereinafter'described understood, that changes in the precise embodiment ofthe inventionherein disclosed can be made within the scope olf jwhatis claimed, without del miting from-the spirit of the, invention. .In the accompanying drawing :-F1gure 1 showsthe inventionin side elevation, parts appearlng m section; Fig. 2 1s a horizontal section taken, in a plane ad acent the platform 'iortion of the vehicle; Fig. 3 is a fragmcntal elevation showing one of the brushes; Fig. 4.
