IRRIGATED BRUSH.

Application filed February 21, 1925. Serial m. 10,755.

Be it known that I, ANTHONY J. MoOoR- naon, a citizen of the United States residing at New Haven, in the county of New Haven and State of Connecticut, have invented a new and useful Improvement in Irrigated Brushes; and I no hereby declare the following, when taken in connection with the accompanying drawings and the characters of reference marked thereon, to be a full, clear, and exact description of the same, and whichsaid drawings constitute part of this application, and represent, inv Fig: l a view in elevation of one form which an irrigated brush, constructed in accordance with my invention, may assume, with the elastic rubber sleeve thereof partly in section.

Fig. 2 a view of the sleeve in central, longitudinal section on the line 22 of Fig. 1.

3 a view thereof in transverse section on the line 33 of Fig. 1.

My invention relates to irrigated brushes, that is to say, brushes which are supplied with water under pressure to facilitate their cleaning action, the object of my present invention being to provide an efficient brush of superior convenience in so far as it is designed to be slipped at pleasure on, over, or off an ordinary hose-nozzle without removing any part thereof.

With these ends in view, my invention consists in an irrigated brush having an elastic rubber sleeve adapted in interior conformation to be slipped at pleasure on, over, or off a standard hose-nozzle, and also for the attachment to it of the ends'of a brush into which water is discharged under pressure from the hose-nozzle.

My invention further consists in a brush characterized as above and having the baseend of its soft rubber sleeve formed with an annular guard-flange for preventing the nozzle from contact with the surfaces being washed.

My invention further consists in an irrigated brush having certain details of construction as will be hereinafter described and particularly pointed out in the claims.

In carrying out my invention, as herein shown, I employ a soft rubber sleeve 5 hav ing a cylindrical chamber 6 formed near its brush-end with an inwardly-projecting, annular retaining-flange 7 and at its butt-end with an annular outwardly-projecting guardflange 8. At opposite points upon the out side of the saidsleeve it is formed with complementary, integral, molded ribs or offsets 9 parallelwith the axis of the sleeve, extend- ,ing nearly through the length thereof, and

designed for the reception of the parallel endslO of the twisted loop-shaped wireframe 11 of the brush proper 12, which, as shown, consists of bristles, but which maybe replaced by tampico, yarn, strips of fabric, sponge, or any other of the several materials used in making brushes designed to be irrigated with water.

As shown, the brusliunit is loop-shaped or oval in form and has its center axis in line with the axis of the sleeve 5, but the brush will often be bent with respect to this axis.

It is designed that the soft rubber sleeve 5 shall be adapted in length, diameter and resiliency to be slipped or crowded on over a standard metal hose-nozzle such as 13 without removing any part thereof, as heretofore has been required, so that the brush may, at the pleasure of the owner, be slipped on and off the hose-nozzle as may be necessary without the use of any tools. When slipped or forced on over the hose-nozzle, its retaining-flange is momentarily displaced, so as to permit the rim 14'. at the end thereof to pass by it, after which the flange contracts and substantially resumes its normal shape, so as to hug the nozzle and retain the soft rubber sleeve 5 thereupon with a suflicient grip to hold it in place when the brush is being used.

It will be understood that the nozzle proper may be somewhat varied in size and design, and that many makes of such nozzles are on the market, but they are sufficiently standardized to enable my improved brush to be used with any one of them, due to the resiliency of the rubber entering into it.

When the brush is in place on the nozzle,

the guard-flange 8 at its butt-end acts to 1 prevent the butt-end of the nozzle from making any contact with the surfaces being washed, this being particularly advantageous in washing automobiles, whereby thelr varnished and polished surfaces are guarded against being scratched.

I have spoken of the sleeve as being made of soft or resilient rubber, by which term I mean to coverany material having the same general characteristics,

I claim: 4

1. The combination With a soft rubber sleeve, of a brush having a loop-shaped frame, having parallel, complementary ends embedded in the outer end of said sleeve at opposite points therein.

2. The combination with a soft rubber sleeve, said sleeve being provided at its outer end With an inWardly-projecting, integral, annular retaining-flange, of a brush having a loop-shaped frame, having parallel, complen'ientary ends anchored in the outer end of the said sleeve.

3. The combination with a soft rubber sleeve, said sleeve being provided at its buttend With an integral, annular, outwardlyprojecting guard-flange, of a brush having a loop-shaped frame, having parallel, complementary ends anchored in said sleeve at opposite points therein.

4. The combination With a soft rubber sleeve, formed at its outer end With an inwardly-projecting, integral, annular retainlug-flange and at its butt-end With an integral, annular. outwardly-projecting guardflange, of a brush having a loop-shaped frame. having parallel, complementary ends embedded in the outer end of said sleeve at opposite points therein.

In testimony whereof, I have signed this specification.

ANTHONY J. MOCORMACK.
