ROTARY BRUSH.

Apbucati'on med June 2s,

To all whm'it moycohcem:

'Belit known' that 'I,.WI'LL1AM" Sioux, a

citizen 0f/the 'United States, residing at SanDiegd in the Vcountyof 'San Diego Vand State of lali fornia,l have, invented cert'ain new and useful Improvements in-Rotary Brushes, :of which the following is a speci- `fcation. u l

My'invent-ion nelates to vcertainv new and in" 'rot-ary brushes adapted to bei secured to. the end of a flexible shaft-or the like, whereby the brush may be inserted in 'the various places that it is desired 'to clean, such for instance as the cylinder' of a .gasoiother engine, tlues of or other` places where deposits ac-` cumulate.

A further object of my invention is topro- .vide'a device'of. the character referred to inwhich. thewirs forming the bristles can and' expeditiously replaced when' and 'also to'provide a device which shall `he sim le and eiicint 4in operation.

With these and other objects in View my invention'consists in certain constructions, combinations and l arrangements of parts the broken,

`preferred-form of which will be first de- Scrbed'in connection with the'aocompanying drawings and then the invention particularly pointed 'out in the appended claim.

:Referring to,4thel drawings` wherein the same part is designated'by the same ref! erence numeral 'whereverH-it* occurs, Figure showing my invei'xtioli inserted through the spark plug opening ofthe cylinder of an automobile so thatthecylinder may be cleaned; Fig. 2 is an enlarged perspective view of the brush and flexible" shaft, with a vthe arrow.

15 designatesa motor which may be of any desired type and suitablyI supported, as, fo`1 instance on a vbracket 6. To the motor is V:connected the shaftf, which may be of any 'desired character, and for the sake of illus` tration-is shown as flexible, and this shaft ,is composed of an inner rotating section 8,

and a'n outer cover 9 as is common in iiexible shafts.v It 1s to be understood', however,

provided on one end gthat'a solid or non substituted if desired. `described form no part l0 designates a ring with a circular groove 11, from :which extend the pairs of'bores 12, into which are placed the U-' o1-hair-pinsl1aped wires 143, ,'with the base of each wire inthe groove 1'1. Preferably, and as shown, the.`outer ends ofthese wires are bent outwardly, as shown at 14, so that the ends will b'etterengage the sides'of 'the construct-ion which it is de` 'sired to clean. The interior of the ring is threaded, land into this threaded'portion isscrewed the sleeve 15, which .has at one end the collar 1G adapted to textend vover the end of the ring covering the groove l1 and securing the wires 4in position'in the ring. The sleeve `15' is centrally bored and preferably screw-tlneaded as shown, in order to be engaged 'hy the threaded endet` ythe shaft 8.

'the cylinders of a gas engine, said engine cylinder being'indicated at l in'Fig. l, the spark plugneed only 'be removed "and my device inserted therein and the motor started' rapidly revolving. The wlres 13 are of such `sir/,e that under l-the rapid rotation of the brush they will spread outr'slightly, so that by moving the device around in the cylinder the deposits' on the `inside thereof canbe rapidly cutI from thel surface. It ,is tobe understood that-the wires 13 are so made as notl to be hard enough to scratch the surface operated up'on.

I'claim as new and desire to secure by LettersPatent is:

The combination with a' ringhaving pairs 'of openingsextending therethrough, of U# ing a collarextending over o ne end of the rlng and securing the wires 1n posltion.

In testimony whereof I aflix my signature- `shaped wires passed througlrthe openings, 1 a sleeve secured in the ring', said sleeve. 'hav
