My invention relates to soap dispensers. I The object of my invention is to provide a dispenser of simple and efficient construction, serving as the handle of a shaving brush, which is normally sealed against leakage, but may be opened to allow a charge of fluid or semi-fluid shaving soap to be fed to the brush and automatically closed after the charge has been fed.
This object, and other advantageous ends which will be described hereinafter, I attain in the following manner, reference being had to the accompanying drawings in which Figure rig a central longitudinalsection through a brush made in accordance with my invention,

Referring to the drawings, 1 indicates a b0 casing, preferably tubular, adapted to coni tain the shaving fluid. The casing carries '7 at one end a rotatable knob 2, preferably having a knurled peripheral face 3. At its other end it has a part 4 preferably of 2 reduced diameter, adapted to receive a cup 5 which is threaded to receive the threaded head 6 of a shaving brush. I prefer to secure the cup in the end of the casing by a forced fit. This cup is closed at its bottom except i for a central opening 7 which leads into a discharge conduit 8, preferably fixed with the cup. which projects within the bristles of the brush, and is provided at its outer end with a valve seat 9. A screw 10 is fixed 43 to knob 2 and has a piston 11 threaded thereon. A valve stem 12, mounted in conduit 8, carries at its outer end a valve head 13 and at its inner end a plate 14 disposed over the end of screw 10. A coiled spring 0 15 mounted between plate 14 and the cup normally holds the valve closed. A cam follower 16 is secured to screw 10 and has a pair of cup shaped cam elements 17 adapted-to receive corresponding elements 18 projecting from the base of a cap 19 having SOAP nrsrnnsnn.

a bearing 20' surrounding the screw, and an internal annular groove 21 in its side wall, one wall of the groove being provided with notches 22 adapted to take over projections 23 on the casing which, when the cap is turned out of registry therewith, bind in the groove and hold the cap in position. A coiled spring 24 mounted between knob 2 and cap 19 holds the cam elements 17 in engagement with cam elements .18.
For securing actuating knob 2-and cam follower 16 to the screw, I provide the screw with an angular end and an annular shoulder 26 and provide the cam follower witha flanged boss 27, extending through the bearing 20 and cap 19,-with the flange disposed under shoulder 26. Knob 2 also has a central opening which fits in the an-' gular end of the screw. By positioning the cam follower and the cap over the angular part of the screw and upsetting the end of the screw both knob and follower are firmly fixed to the screw. 7
Assuming the parts to be in their idle position and that part of the casing in ad vance of the piston to be charged with the liuid, the operation is as follows:
' A partial rotation of knob 2 advances the piston upon the screw andat the same time,
rotates cam follower 16 thereby causing cam elements 17 on the follower to slide relatively to cam elements 18 of cap 19 and shift the follower axially relatively to the 7 cap. This advances the screw axially and, the screw being in engagement with plate 14 on the valve stem, causes the valve to open. A half revolution of knob 2 brings the cam elements into registryv again. The screw is then retracted by spring 2% and the valve closed by spring 15. If a further charge of shaving cream is desired, it will be provided by another-half revolution of the knob.
lVhile I have described my invention as taking a particular form, it will be understood that the various parts may be changed without departing from the spirit thereof, and hence I do not limit myself to the precise construction set forth, but consider that I am at liberty to make such changes andv alterations as fairly come within the scope of the appended claims.
Having thus described my invention, what I claim as new and desire to secure by Letters Patent .is:
