SI-IAVING-BRUSH.

Specification of Letters Patent.

Patented July 18, 1916.

Application filed March 31, 1915. Serial No. 18,338. f

T all 'whom t may concern Be it known that I, O'scAR S. McCUnDY, a citizen of the United States, residing at Wilkinsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Shaving- Brushes, of which the following is a specication, reference being had to the accompanying drawings.

My present invention relates to new and useful improvements in brushes and has particular reference to those of the .type employed in applying shaving lather.

The principal object of the invention is to construct a shaving brush in which the bristles are accompanied by a hollow handle wherein may Vbe contained -a quantity of liquid soap which can be fed at the will of the user from the handle into the bristles.

Another object is .to provide the bristle carryingend of the handle with a soap outlet and valve seat and to accompany the lat,-` ter with a valve whichl is normally held 1n closed position by 'a spring, but may be readily opened by pressure of the users thumb on the end ,of thehandle.

The above, and other incidental objects of a similar nature, which will be hereinafter more specifically treated are accomplished by such means as are illustrated in the accompanying drawings, described in the following specification, and then more particularly pointed out in the claims which are appended hereto and form part of this application.

With reference to the drawings, wherein there has been illustrated the preferred einbodiment of this invention, as it is `reduced to practice, and throughout the several views of which similar reference numerals designate corresponding parts, Figure 1 is a longitudinal section taken medially through the brush with the parts thereof in operative assembled relation; Fig. 2 is a section on the line 2-2, of Fig. l; Fig. 3 is a. section on the line 3 3, of Fig. 1; Fig. 4 is a section taken diametrically through the preferred form of cap; Fig. 5 is a section taken diametrically through a modified form ofl cap; ,and Fig. 6 is a section taken diametrically through the bristle head, showing the modified form of valve seat.

As best shown in an entirety in Fig. 1 of the accompanying drawings, the brush embodying my invention includes a bunch or tuft of bristles 10, a hollow handle 11, a

l 4The bristles 10 are seated in an annular head. piece 15. This member 15 is disposed within the terminal of the handle 11 and is held against withdrawal therefrom by the inwardly directed annular flange 16. A valve seat 17 is-provided for the valve and is accompanied by a circular flange 18 which extends laterally from its upper terminal and seats atits periphery against the internal annular' shoulder 19 formed in the handle 11 by stamping the wall thereof outwardly, as shown in Fig. 1. The head piece 15 bears against the flange 18, as is also best disclosed in Fig. 1.. If desired the modified form of valve seat shown in Fig. 6 may be employed. In this form, the flange 18 is eliminated and the valve seat is held against withdrawal from the head l5 by an annular external rib 18, which seats ina receiving recess formed in the head piece 15. The valve 12 is substantially cylindrical and carries at its lower terminal an outstanding annular rib or head 20 which is beveled on its upper face, as at 21'to seat against the beveled face at the lower end of the valve seat 17. Longitudinal facial grooves or channels 22 are formed in the valve 12 `for the passage of liquid soap from the yhandle 11 into the space 23 defined within the bristles 10. The channels 22 terminate at their lower ends, `at thehead 20 of the valve so that when the valve is in closed position, communication between the interior of the handle and the chamber 23 is .cut-off.

The valve is normally maintained in closed Y position by means of the flat spring heretofore designated by the numeral 13. The spring 13 is preferably rectangular in shape and is of a length equal to the diameter of the handle 11, at a point thereof immediately above the inwardly extending annular shoulder 24, upon which the terminals of the spring rest. The spring is provided with a central opening, through which projects the stern 25 ofthe valve. Onthe upper terminal of this valve stem, are threaded avstop nut 26 and the lock nut 27, which latter holds the member 26 against rotation. Obviously, the member 26 can be adjusted on the valve stempto take up any decrease in elasticity of the spring 13, or wear of the valve or seat, so that the valve will be normally', tightly seated. The neck 28 of the Y cated rivet 30b and is provided at its perimeter with a sealing washer 30C of rubber, leather or any other similar material. Normally the sealing washer is held in engagement with the inner face ofthe cap, thereby sealing the vents 30 but the inward flexing of the crimped portion of the cap, when the plunger rod is to be operated, will cause. the sealing washer 30a to move away from the inner face of the cap, thus permitting the air to enter through the vents 30. ln the modified form of cap shown in F ig. 5, the air vents 30 are located on the fiat portion of the cap' instead of in the crimped portion thereof. Sealing pads indicated at 30d are provided to normally seal these vents.

The actual construction and arrangement of the several parts having been disclosed,

it now remains to explain briefly the manner in which the valve is opened, when the brush is in use, to permit the passage of the liquid soap from the handle 11 into the head of the bristles. ln this connection, it will be observed that the user may, having grasped. the handle with his fingers, bring his thumb to bear upon the spring `31. |llhe inward flexing of this spring wall 31 will cause the head of the rivet 33 to engage the valve stem 25 and push this member longitudinally through the handle, against the tension of the spring 13. rThe longitudinal movement of the valve stem causes the head 20 to move away from the valve seat, with a resultant establishment of communication between the handle 11 and the chamber 23 in the bristles, through the passage 22. is soon as the operators thumb is removed from the spring wall 31, the spring 13, of course, acts to immediately return the valve to closed position.

In reduction to practice, it has been found that the form of this invention illustrated in the drawings, and referred to in the above description as the preferred form, is the most efficient and practical; yet realizing that the conditions concurrent with the adoption of this device will necessarily vary, it is desirable to emphasize the fact that various minor changes in details of construction, proportion and arrangement of parts may be resorted to, when required, without sacrificing any .of the advantages ot this invention, as defined by the appended claims.

lhat is claimed is 1. A brush including a hollow handle, a tuft of bristles connected to one end thereof, a valve controlling communication between the interior of the handle and the bristles, valve stem for the valve, said stem extending longitudinally through the handle, a cap threaded on the end of the handle, remote from the bristles, an external shoulder formed in the handle at the cap-carrying 'terminal thereof, a ilat spring resting terminally on said shoulder, a stop nut carried by the valve stem, and engageable by the spring, whereby the spring normally holds the valve in closed position, and a spring formed integrally with the cap member, said spring being adapted to be flexed inwardly into engagement with the adjacent terminal of the valve stem for yopening the valve.

A brush including a hollow handle, a tuft of bristles connected to one end thereof, a cap threaded on the other end of the han` dle, said cap being provided with air vents and being relatively flexible, a sealing plate mounted against the inner face of the cap,

vand disposed to normally seal the openings therein, said sealing plate being adapted to retain its flat original shape when the cap is eXed inwardly, whereby the air vents are opened upon such inward flexing of the cap.

3. A brush including a hollow handle, a tuft of bristles secured to one end thereof, a

vcap for the other end thereof, said cap being relatively iieXible and being provided with air vents, a sealing plate mounted against the inner face of the cap, a fastening member passing through the sealing plate and through the cap for securing' the plate to the cap, said plate being relatively stid and flat, and a non-metallic sealing member mounted on the sealing plate and engageable with the cap for normally sealing the air vents, said plate being adapted to retain its flat form when the cap is flexed inwardly, whereby such inward flexing of the cap,` will open the air vents.

t ln testimony whereof l hereunto aiiiX my signature in the presence of two witnesses.
