' ApplicatiomFebruary- 7, 1950;:Serial No. 142;760-

This inventionrelatestoshaving brushesand more, particularly to thetype-in which the brush "z-caims; (01. 222-390) is -providedwith a-soapgsquirtin nozzle within the-brush, the-amount-of-soap being determined by: the amount of pressureon the soap in the soapreser-voir.

.The object -of the inventionistoprovide improved means for controllingsuch pressure.

-.Heretofore it .has-been proposed to use helical springs to-exertsuch.pressure, but in the-use of p ss b en lfound that their inherent resiliency subject them to a finaluncontrolled pressure,=which whenexertedupon-the soap contents extrudes toomiich soap.

The present invention has'for its object to proplurality of "spring-blades secured to each other 1;

at alternate-ends;- and heldin normal collapsed position and capable of being extended under their inherent resiliency thus pulling on the piston to tighten its thread engagement with the sleeve and on the cap to force it against the end of the sleeve.

The invention will be further described, embodiments thereof will be shown in the drawings, and the invention will be finally pointed out in the claims.

In the accompanying drawings,

Fig. l is a vertical central section of the improved device, with the shaft collapsed as in normal position;

Fig. 2 is a like section with the shaft extended;

Fig. 3 is a horizontal section on line 33 of Fig. 2;

Fig. 4 is a perspective View of the cap closing the end of the sleeve;

Fig. 5 is a horiozntal section taken on line 55 of Fig. 2; and

Fig. 6 is a section similar to Fig. 2, with the extended shaft made of fused blades.

Similar characters of reference indicate corresponding parts throughout the various views.

Referring to the drawings, the structure shown in general is like the structures shown and described in my applications Serial No. 775,195, filed September 20, 1947, and Serial No, 45,950, filed August 24, 1948.

" As; known,- the sleeve 1 D is screwthreaded asat I I: shown-in :sectionatits interior as at'-l 2, and a member I 3 with a soap dispensing' nozzle M has exterior -screwthreads -15 engaging the i screwthreaded sleeve 10. A cap l6 hasinterior screwthreads l-Ba toengage the screwthreads lli of the member I3. I

The improvement consists r in the soappressin piston -=2ll, which has; exterior sc-rewthreads --20a to engagethe interior-- screwthreads of the sleeve l0. and which by rotation moves longitudinally in the sleeve, for expending soap through the nozzle. The sleeve -l 0 at-its 1oweropenend -is closed by a cap-2 l enveloping theexterior; of the sleeve l0, bein formed of a flat diske22-and flanges 2-3, and is-rotatable on the-end oi -the sleeve.

Disposed. between-the cap 2 I and the. pistonis a collapsiblebladed turning-shaftlli whichhas.v

ture=alternately atopposite sides of the axis or the shaft. The metalsused issuchas i to .be substantially: rigid but has an inherent resiliency. to permit an accordion like expansion whenthe ends are pulled in opposite directions. The diametrical ends of the disks 26 are secured to each other by rivets 27 or the like, as shown in Fig. 3. In place of rivets, the ends may be fused together as at 21a in Fig. 6. The disks there shown have a waist line 28, but may be circular in contour or of other suitable shape. One end of the shaft 25 is secured to the piston 20 and the other end of the shaft 25 is secured to the cap 2|, by rivets 30 or the like. The shaft 25 when collapsed takes up very little room as shown in Fig. 1, wherein the blades are in faying relationship and parallel with each other. When the shaft 25 is extended as shown in Fig. 2, it exerts a pull on the piston 20 and forces its screwthreads against the screwthreads of the sleeve forming an air tight seal, which is important, particularly to prevent the passage of the soap in outward direction, and the inlet of air in the other direction, which might cake the soap cream at the screwthreads.

At the same time the expansion of the shaft 25 tends to force the cap 2| against the sleeve l0, and hold the cap 2| against the end of the sleeve ID. This action takes place to almost the collapse or nested position of the shaft 25, and when the shaft 25 is nested it still holds the cap on,

as the shaft 25 is in its normal collapsed position.

To further assist in holding the cap 2| on the sleeve ID, a crown of metal 3| (Fig. 4), having a plurality of resilient peripheral teeth 32, is secured by a rivet 33 or two to the cap 2|, and the 5 teeth then engage a circular groove 34 inside of the sleeve in proximity to its end.

The low depth of the closed shaft as shown in Fig. 1, enables a short sleeve lo to be provided,

so that sleeve [0 and cap l6 constituting the en- 10 tire brush handle, is not larger but smaller than the ordinary brush handle of the common shaving brush now on the market. K V

The mechanical parts of the improved device provide a direct transfer of rotative force trans- 5 lated to a longitudinal movement of the soap Pressing piston, without any"after"'resiliency as is the case with helical springs. A rotation of the cap is instantly conveyedto the rotation of the position. Simultaneously, the piston threads are stainlessspring steel; and the other parts preferably of aluminum or plastic, such as Tenit, or thelike. I t

The assembly of the piston blade shaft,'and cap can be taken out of the sleeve in its entirety, and cleaned, if necessary, or for repairs, if any. u The materials used are rust-proof or non-corrosive.

The cap shown as having its rim on the outside of. the sleeve, may be arranged tobe within thesleeve. 7 i

I wish it to be understood that I do not desire to be limited to the exact details of construction shown and described, for obvious modifications will occur to a person skilled in the art.

1. In a soap containing handle having an interiorly threaded sleeve for containing the soap, and an exteriorly threaded piston movable in said sleeve on the rotation of the piston, the combination of a cover for the sleeve, and a longitudinal 4 collapsible shaft disposed between the cover and thepiston, said shaft consisting of a series or 4 superposed blades normally in planes at right angles to the longitudinal axis of the sleeve and smaller in length than the inner diameter of the sleeve, said blades being serially joined to each other at their alternate peripheral margins, with one end blade secured to the piston, and the other end blade secured to the cover, all of the intermediate blades extending across said axis, said blades when nested being in parallel planes substantially contacting with each other, and said blades being adapted to be separated from each other on the movement of said piston away from said cover, excepting for their peripheral margins, whereby on the rotation of the cover, the piston is simultaneously rotated by the radial turning movements of the blades, without transposing any rotary force to a longitudinal force, said shaft when extended, having an inherent resiliency to return to its nested position.

2. In a soap containing handle having an interiorly threaded sleeve for containing the soap, and an exteriorly threaded piston movable in said sleeveon the rotation of the piston, the combination of a cover for the sleeve, and a shaft dis posed between the cover and piston, said shaft consisting of a series of superposed tensional end blade secured to the cover, whereby on the r otation of the cover the piston is rotated, and said unit is extended and has an inherent resiliency to press the threads of the piston against the threads of the sleeve, and to press the cap against the sleeve end.
