" JaorI RYanus Application filed April 30,

This invention relates toj'a new and useful device in the nature of a rotary brush espeeially adapted for use by barbers, tonsorial artists, hairdressers and the like, for the pur-' pose of more readily and rapidly brushing hair. 1 c y The object of the invention is to provide a rotary brush of simple construction and arrangement of parts embodying certain new I and novel features hereinafter more fully describechclaimed and ill panying drawing. v

I Fig. 2 isa top plan view thereof. v f I Fig. 3 is a central verticalisectional vie thereof. f f v V Fig. 4 is atransverse sectional view taken on the line 41-4 of Fig. 1. 9 Fig. 5 is an enlarged fragmentary side elevational View illustrating in particular a ..furtheridevelopment of the handle member as embodied in my improveddevice. I t

As here embodied 'my improved rotary brush comprises a brush body memberlOg of cylindrical construction, having secured thereto, or imbedded thereln bristles 11, extended therefrom, so as to provide a cylindri- #39 cal brush. The body member 10 has formed therein at its lower extremity an axial opening adapted to receive the extended element 12 of the collar 13, which is secured thereto in any desired manner. The collar 13 has thereto by the threaded member 18"mounte'd' in the enlarged extremity of tlie said shaft 17 The above described construction is such as cleaning, replacement or the like.

The conventional ball bearings 19 and 20,

preferably of the combination rotation and thrust type are mounted intermediately on the shaft '17, and maintained thereon'by the ustrated in the accom formed therein an axial opening adapted to secure the pin 14, secured [thereto by the threaded member l5 mounted in the collar 13. V The 11114. is extended'from' the collar 13 and will permit the said brushitobe easily and readily removed from the said shaft, for

The shaft-'17 is providedwith. flange 23, positioned at or near the upper extremity thereof, for the purpose as hereinafter set forth. f The above described construction is. such as will permit the. shaft, 17 to be rotatively mounted on the ball bearings 191affid f The handle as embodied in myimpro ved rotary brush comprises a pairof handle'members 24- and 25, similar or identically shaped of substantially fiat side construction, andprovided with arcshape, convex or'cur'ved edges 26.3and 27 respectivelyfand opposite edges 28 and 29 respectively formed or The said handle members are remo-vablysecured together by means of thethreaded me1nbers'30, and have formed therein a longitudinal opening adapted to freely'receive the V shaftlZ'and the collars 21 and 22 and to engage or grip the ball bearings 19 and 20, as a means of rotativelysupporting the shaft in the said handle members. The said opening formed in the handle members is provided with anenlarged portion adapted to receive the flange 23 of the shaft 17, so as to permit thesaid flange to function as a thrust support combination thrust ball bearings.

for the said shaft, co-acting with the said the user'of my improved ro- The engaging member 31 is slidabl mounted in the opening'32 formed in t e lower portions of'the handle members and is provided with anextended element 33 normally held somewhat extended in the lower portion of the abovementionedlongitudinal opening formed in the said handlemembersby means of the expansion spring 34 positioned in the opening 32, directly at the rear of the engaging member '31 and in engagement therewith. The said spring is maintained therein by the [threaded member 35, threadedly in engagement with the said spring. "The lower extremity of the shaft 17 has formed thereina slot 36, adapted torec'eive theusual to extended from the usualflexible shaft 7 88, such as is commonly used to rotate or "drive appliances, such asmassaging tools,

dentists drillings, hair clippers and the like,

and which is operatively attached to a suitable electric motor, watermotor or the like,

' as a means of rotating my improved rotary brush. I

- The above I as will permit the extended element 33' of'the engaging member to automatically. engage in the usual co-axial groove" formed in the fixture 37, for the purpose of permitting myimproved rotary brushl'to be readily and easily attachedjor detachedfrom the flexible shaft, which .is'highly desirable and convenf ient when hair clippers, a massaging tool or the like are to be used, as a means of providing interchangeability of the said appliances.
