UNITED STATES IRA A. BURNETT, OF CHICAGO, ILLINOIS.

SOAP-DISPENSING HAND BRUSH.

Application filed March 1, 1924. Serial No. 696,127.

To all iii/tom it may concern:

Be it known that I, IRA A. BURNETT, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Soap-Dispensing Hand Brushes, of which the following is a specification.

This invention relates, generally, to improvements in brushes for use as toilet articles or devices, for scrubbing and cleansing the hands, and has particular relation to a type of such brushes in which the body of the device is provided therein with a container for liquid soap or a cleansing agent, and with co-operating means for dispensing said agent from said container onto the bristles of the brush; and the objects of the invention are, first, to provide a soap-dispensing hand-brush, of such construction and arrangement of its parts that it can be very economically manufactured and its parts readily assembled; second, to furnish a hand-brush of such shape, size and construction and arrangement of its parts that it can be securely held for scrubbing or cleansing action and manipulated for the ejection of the cleansing agent onto the bristles in the desired quantities and at the desired times by one hand of the user; and third, to provide a brush of the above named general character, which shall be attractive in appearance, compact in form, strong, durable and highly etficient in operation.

Other objects and advantages of the invention will be disclosed in the following description and explanation.

In the accompanying drawing, which serves to illustrate an embodiment of the iuvention,-

Fig. 1 is a plan view thereof.

Fig. 2 is a longitudinal sectional view taken on line .22 of Fig. 1 looking in the direction indicated by the arrows, and i Fig. 3 is a cross-sectional view taken on line 83 of Fig. 2 as indicated by the ar rows.

The reference numeral 5 designates the body of the device, which body is substantially rectangular in shape and by preference made of sheet metal. As is clearly shown in Figs. 2 and S, the body or casing 5 is reduced downwardly at each of its sides, thus providing a. lateral enlargement 6 at each side of its upper portion, thereby pro viding a body which can be conveniently held in the hand without undue gripping pressure. The extreme lower part of the casing 5 is slightly offset inwardly as at 7, from which offset portion the body is provided with a downward extension or perimeter 8 of less area than that of the body 5 just above its offset portion 7. This exten sion 8, however, conforms preferably to the shape of the body 5 when the same is viewed from the bottom; that is to say, the said extension is substantially rectangular in shape. A plate 9 of metal of a size to fit snugly in the upper portion of the extension 8 is employed to form the bottom closure of the body 5 and said plate maybe soldered at its edges to the inner surface of the body at the offset portion 7 thereof, as will be readily understood by reference to Figs. 2 and 3 of the drawings. ment it is manifest that the extension 8 will have the form of an inverted tray, which is for the reception of the back 10 of the brush. which is provided in the ordinary or any preferred way with bristles 11 of the usual or any desired kind.

The back 10 of the brush is by preference made of fibre or such material as will not expand materially when subjected to water, so that the back 10 of the brush may be inserted and removed when desired from the hollow extension 8, it being understood that said back is held within said extension by frictional contact therewith. The back 10 is provided at its middle portion with an opening 12 for the purpose to be presently explained.

The body 5 is provided in one of its ends preferably midway between its sides with an opening 13 which is located near the top of the-body as shown in 2. At its opening 1 1- closed by a screw-plug 1, which opening is employed to permit of liquid soap or a cleansing agent to be supplied to the cavity of the body.

Located in the upper portion of the body is a tube '15 which has its end adjacent the opening 18 in the body 5 annularly enlarged as at 16, which enlarged portion is internally screw-threaded for engagement with a gland or follower 17 the outer portion of which rests on the outer surface of that end of the body 5 in which the opening 13 is located when said gland is screwed up. Between the inner end of the gland 17 and the contracted portion of the enlargement 16 of the By this arrange opposite end the body 5 is provided with an tube 15, suitable packing 18 is located to prevent leakage through the said tube. That end of the tube opposite the opening 13 may rest and be secured by means of solder or otherwise against the inner surface of the end wall of the body 5 having the inlet opening therein.

Located in the tube 15 is a plunger designated as a whole by the numeral 19, which has at its inner end a reduced portion 20 around which a coil spring 21 is interposed between the inner end of the tube 15 and the shoulder 22 of the plunger 19 afforded by the reduced portion 20.

The plunger 19 is extended through the gland 17 and may be provided at its outer end with a push button as indicated at 23 by dotted lines in Fig. 1 of the drawing, or it may be provided at its outer end with a cross-bar Le having at each of its ends an arm 25 extended in substantial parallelism with the plunger 19 and fitted for reciprocation in sockets 26 provided on the upper portion of the body 5 for guiding said arms. By this arrangement it is manifest that the plunger 19 can be reciprocated by applying pressure to the push button 23 or the bar 24 y means of the thumb or finger of the hand in which the device is held.

By reference to Figs. 2 and 3 it will be seen and understood that the plunger is provided at its middle portion with a flattened part 27 which is located vertically or edgewise with respect to a tube 28 extended downwardly from the tube 15 and through the opening 12 in the back 10 of the brush as well as through asuitable opening in the plate 9 which forms the bottom closure of the body of the device. This flattened portion 27 of the plunger 19 is formed with an inclined slot '29 which is open at its lower end and is for the reception and operation of a pin 30 carried by the spaced prongs 31 on the upper end of a piston rod 32 which extends through the tube 28 and has on its lower portion externally of the said tube a gasket 33 of rubber or other suitable material to close the lower end of said tube. This gasket is held in place by means of a Washer 3 1- and a nut engaging the lower end of the piston rod. Just below the prongs 31. of the rod 32 the latter has mount-- ed thereon a piston 36 which serves to assist in discharging liquid or other cleansing agent from the body 5 through openings or ports 37 in the tube 28 just above the plate 9 of the body and from thence through the lower portion of the tube 28 onto the bristles.

It will be understood by reference to Figs. 2 and 3 of the drawing that when the parts are in the positions shown in said figures, the piston 36 will be located above the ports 37 and that the lower end of the tube 28 will be closed by the gasket 33, thus preventing the escape of the cleansing agent. The action of the spring 21 will hold the plunger 19 in said position until it is desired to discharge liquid or cleansing agent from the container, which may be effected by pressing the plunger 19 at its outer end inwardly, in which operation a charge of liquid will be delivered to the bristles and the ports 37 will be temporarily closed. By removing pressure from the plunger the spring 21 will er;- ert its tension thereon and cause the parts to assume their normal positions or about as shown in Fig. 2 of the drawing.

From the foregoing and by reference to the drawing, it will be readily understood and clearly seen that by my improvements the liquid soap or cleansing agent within the body 5 can be discharged therefrom intermittently or in charges if so desired, or, if a continuous discharge should be desired, this can be effected by pressing the plunger 19 inwardly a suilicient distance to open the lower end of the tube 28 but insufliciently to close the ports 37 by means of the piston 36 actuated by said plunger. In either instance it is manifest that the liquid soap or cleansing agent will be discharged onto the bristles of the brush, and that by wetting or inoistening the same and rubbing them on the hand, the latter can be quickly and effectively cleansed.

While the device is more particularly intended for the use of liquid soap as a cleansing agent, yet it will be understood that linely powdered cleansing compound may he used with good results, but perhaps not as satisfactorily as the liquid.

Having thus fully described my invention, what I claim. as new and desire to secure by Letters Patent is:

In a device of the class described, the combination with a hollow body, of a tube located within said body and supported at at least one of its ends by said body, of an outlet conduit communicating with. said tube between its ends and extended through said body at an angle to the tube, said conduit forming a partial support for said tube. a brush back mounted on the body around the disoharging end of said conduit, a rod lo catcd in said conduit and having at its in nor end a transversely disposed projection and at its other end 171611115 to close the discharge end of said conduit, a plunger mounted in said tube for reciprocal movement therein and having between its ends a reduced portion provided with an inclined slot to cooperate. with the projection of the aforesaid rod for imparting reciprocating n'ioveu'ienl' to the same when said plunger is reciprocated.
