Application August 4, 1941, Serial No.405,391

(Cl. 22d- 79) 2 Claims.

This invention relates to shaving brushes of the fountain type and it is one object of the invention to provide ashaving brush having a combined handle and soap holder provided with an improved arrangement of piston and threaded stem for'expelling soap from the hollow handle or container, a spring being associated `with the piston for assisting movement of the piston in its soap expelling direction when the stem is turned in the proper direction.

Another object of the invention is to provide a spring which is housed within the hollow handle and conned between the piston and the outer end of the handle so that it exerts pressure upon the piston and prevents tilting of the piston and also creates binding action between threads of the stem and the piston so that the pistonwill be shifted longitudinally in the handle when the stem is turned instead of turning withV the stem.

Another object of the invention is to provide a fountain brush wherein the stem is rotatably mounted through a removable cap for the rear end of the hollow handle and carries a turning member of such formation that it may be easily grasped and turned to rotate the stem and shift the piston longitudinally in the handle.

Another object of the invention is to provide an improved head for the front end of the handle, the head being rmly mounted and provided with a discharge neck externally threaded to removably receive the brush head and of such diameter that there will be no danger of clogging and a thorough cleaning may be eiected when necessary.

Another object of the invention is to provide an improved brush head adapted to be screwed upon the threaded neck of the handle when in use, the brush, when not in use, being placed within a cylindrical shield or container which is detachably applied to the front end of the handle and the brush completely enclosed to protect it from dust and also prevent it from soiling other articles if placed in a traveling bag.

In the accompanying drawing:

Fig. 1 is a view showing the improved shaving brush partially in elevation and partially in longilv tudinal section.

Fig. 2 is a sectional view on an enlarged scale taken longitudinally through the shaving brush.

Fig. 3 is a view similar to Fig. 2, showing the shaving brush ready for use.

Fig. 4 is a sectional view on the line 4--4 of Fig. 3.

Fig-5 is a transverse sectional view on the line 5-5 of Fig. `3.

Fig. -6 is a side elevation showing the brush ready-foruse. y

This improved shaving brush has a hollow handleI which is formed of sheet metal or other suitable material and is formed at its front and rear ends with externally threaded necks 2 and 3, and outstanding beads 4 and 5 at inner ends of the necks. A head 6 consisting of a metal disk, is seated in the bead 4, to close the front end of the hollow handle or soap container I, and this headfis provided with an externally threaded neck I of suchdiameter that soap may be easily disn charged through the neck without danger of clogging and also a thorough cleaning effected when necessary.

To expel soap from the hollow handle, thereI has been provided a piston 8 which is formed of metal and basa vforwardly projecting marginal ange 9, the piston being of such diameter that it lits snugly within the handle with its ange 9 in snug contacting engagement with walls of the handle. A boss Il) extends rearwardly from the center of the piston and through this boss is formed a threaded opening I I to receive a threaded stern I2, by means of which the piston is shifted longitudinally in the handle.

From an inspection of Figs. 2 and 3 of the drawing, it will be seen that when the stem is turned in the direction for advancing the piston toward the front end of the handle, the soap I3 in the handle willY be forced through the discharge neck 1. The stem has an unthreaded portion I3 which isrotatably received through an opening I4 formed at the center of a cap I5 which is screwed on the neck 3 and constitutes a removable closure for the rear end of the handle. A nut I6 is screwed on the stem and bears against a washer I'I so that the washer will be firmly held in place and the head I8 is embedded in plastic I9 lling the metal shell 2|] of the turning head 2|, by means of which rotary motion is imparted to the stem to shift the piston longitudinally in the handle. 'Ihe unthreaded portion of the stem is of such length that when the nut is screwed tightly into place, the turning head 2| will be close to the cap I5 and the head may Lbe turned easily without wobbling movement.

When the piston is shifted rearwardly in the handle to a position close to or in engagement with the nut I6, and the cap is unscrewed fromY ther neck 3 of the handle, the piston may be withdrawn from the handle and the handle filled with soap in the form of a cartridge of shaving cream.

The cap is then replaced and the stem will penetrate the cartridge and extend longitudinally in the handle axially thereof. 'I'he spring 22 will be under compression and, as the vstem is turned to Y shift the piston forwardly, pressure of the spring ing to a canted position in the handle. The fact 'j that the neck 'l is of large diameter, 'permits the shaving cream to be readily discharged through it as the piston is advanced forwardly in the handle and when the soap is exhausted and the cap l5 unscrewed and the piston with-l drawn from the handle, the interior of the handle and the neck may be very easily cleaned and sterilized before the handle or casing is refilled.

The brush head, indicated in general by the numeral 23, has its bristles 24 set in a backing or block 25 of vulcanized rubber or other suitable material. This backingblock is of annular formation and is enclosed in a metal casing 26 which fits snugly about the block and is formed with a central sleeve or liner 21 having internal threads 28 for a portion of itslength so that it may be screwed upon the neck 1 of the head 6 and detachably mount the brush head for use, as shown in Fig. 3. The sleeve and the portions of the bristles projecting from the casing, dene a pocket 29 which is to be filled with shaving cream forced from the neck 'I when the piston is advanced toward the front end of the hollow handle. It will thus be seen that the brush may be charged withfshaving cream and this creamI worked into a lather when the brush is Wet. When the brush is not in use, it is dropped into a cylindrical cover 3l! which is of such length that its open end portion projects from the brush a suiiicienttdstance to permit it to be screwed onto the threaded neck 2 of the handle. The brush will then be entirely enclosed and it may be placed in a traveling bag without soiling other articles in the bag. A small opening 3| is formed in the cover 30 so that air may enter the cover and dry the bristles when the brush is dropped into the cover and the cover screwed upon the handle.'

Having thus described the invention, what is claimed is:

l. In a device of the character described, a cylindrical container having externally threaded front and rear end portions and outstanding beads at in 'ner ends of its threaded` portions defining internal grooves about walls of the container, a head fitting in the front end portion of said container and seated in the groove formed by the front bead, acap screwed upon the threaded rear end portion of the container and abutting the rear head bead, said-,cap having formed therewith a central opening, a threaded stem 4 rotatably mounted through the opening of the cap and held` against longitudinal movement, and a piston in the container threaded upon the stern and moved longitudinally in the container as the stem is turned.

2. In a deviceof the character described, a cylindrical container having ahead at its front end formed with an outlet, a removable cap for the rear end of the container formed with an opening at its center, a threaded stem rotatably mounted through the opening of said cap and extending through the co'ntainer axially thereof, a piston tting snugly within the container and having a rearwardly extending boss at its center formed with a threaded stem-receiving opening, the stem bengthreaded through the opening and shifting the v piston longitudinally .inthe container when turned, and ahelical spring coiled about the stem and tapered forwardly and having its rear end bearing against the cap and its front end bearing against the piston about the boss, said spring being under compression for urging the piston forwardly' and having its frontend tting snugly about saidboss tocenter the spring and prevent canting of thepiston and turning of the piston Withthe stem.
