WALL-CLEANE Specification of Letters Patent. Patented Nov-12,1912. Application'fl led ma 31,1912. Seria1-No.-700,904.

Toallpwhont it may concern i v Be it known that I; Romano Rosa, a .citizen of the United States, residing at Lou'i'sville in' thel State of Kentucky, have ,in-.

of-vvhich thetollovving' is a s'pe ification.v

iMy invention relates particu a'rlylto wall cleaners driven by motors mounted ona movable stand and has for' 'its object toinirow the strnetureandeifieierioy thereof. i It consists of novelfeatures and parts and combinations of the same which will be more .fully'described hereinafter: and then pointed out inthe c1aim i. I

A practical embodiment of .my invention is shown in the accompanying drawings, in hich- Fignre Fig, 2, an

3, a detail secti'o'nalview' on the line '3 3 of Fig. "1.

' My invention consists essentially a in as theshaft'of a 'motor a fixed driving wheel-and a swinging arm provided saidiarm at the operating point.

It further consists in mounting said. motor on a movable truck, in making said armadextensible to facilitate-t the placement and adjustment of the drlvln'g cha1n,'

justably' and in providing'a handle onthe outer part of said arm for controlling the same.

The motor 2 is mounted on the movable truck-'1 and'is provided with the shaft 8. To the shaft 3 is fastened the main driving Wheel 5,'preterably a sprocket Wheel; with itslhub slipped CV61 the sleeve 4. The sleeve 4: isiadapted' to contain the balls 6 which form a ball-bearing for the arm 7-. The arm vented: a new and Improved all-Cleaner;

1 is a vertical longitudinal cross-Y section of my device, partly in elevation;

end elevationthereof; and Fig. fl

.lng or cl ttlng tool 1n its bite onthe Wall without pushlng strain on the part ofthe.

7 has an 'adjnstable extension 8, which-is fixed by the set-screw 11. being tightened mto one. of the teeth-10. This adjustment .allows the sprocket chain; 17 to be readily tightened or'removed. Theextension 8 is provided with a handle 9 near the operating position Preferably'at its end is placed the u secondary-shaft 12, driven by thesecondary sprocket Wheel 13., To give perfect adjustment to- 'the wall18, the container 15 for- {cuttingor cleaning instrument! 16' is connected 'to the shaft' 12 by the universal joint. 14.

" Mv device "is particularly. adapted to mosaic" work Where considerable cutting-has tobe done,' and it is evident that the entire surface of a vertical Wall can be readily covered by simply "moving the truck'along parallel thereto at the. proper distance therefrom. This gives great rigidity to the cleanoperator:and.mak es it simply necessary for him to overcome gravity when the arm 7 is in "an oblique position.

- Ido IIOtllmIt myself f-urther than is indicated in'the claim which'follow's.

I claim:

' A motor provided with a shaft an-exteni sible arm onsaid shaft rotatable independently thereof, a sprocket wheel 'on said shaft,

.a sprocket Wheel and shaft and-rotary 'cleaner' on said arm, and a continuous chain" connecting said sprocket whe'els and adapted to drive said cleaner.
