FOUNTAIN SHAVING BRUSH Filed Feb. 17, 1952 E ic/ 7/ Z5 7 Patented Aug. 23, 1932 UNITED STATES PATENT OFFICE RICHARD WILHELM vomEOHENHOEF OE.BALTIMORE, MARYLAND FOUNTAIN SHAVING BRUSH v I Application filed February 17, 1982, Serial No. 593,604, and in Germany February 24, 1931..
This invention relates to certain new and Figure '5 is a cross-sectional view taken on useful improvements in fountain shaving line 5 of Figure 3; and I brushes. 7 Figure 6 is a cross-sectional view taken The primary object of the invention is to on line 6-6 of Figure 3, showing the rectan- 5 provide a fountain shaving brush wherein a gular telescoping sections of the piston rod. 55,

A head and piston, as contrasted with prior decentral opening is formed in the bottom wall vices wherein the extensible piston rod for 14 of the brush head and is surrounded by a 7 operating the piston is formed of cylindrlcal tubular boss 16 extending into the central telescoping sections relying upon friction beportion of the body. of the bristles 18 for the tween the parts for the feeding of the piston. delivery of shaving cream or the like from WVith the above and other objects inview the tubular handle onto the brush bristles.
that will become apparent as the nature of To accomplish the feeding of the shaving so the invention is better understood, the same cream from the tubular handle onto the brush consists in the novel form. combination and bristles, there is provided a piston 17 threadarrangement of parts hereinafter more fully ed into tubular handle 10, the shaving cream described, shown in the accompanying drawbeing introduced into the tubular handle 5 ing and claimed. when the brush head is removed therefrom In the drawing and the piston 17 is shifted in the tubular Figure 1 is a side elevational view of a handle to a position adjacent the inner end fountain shaving brush constructed in acthereof as illustrated in Figure 4. The 0pcordance with the present invention; -crating means for the piston 17 includes an Figure 2 is an inner end elevational view; extensible piston rod formed of telescoping Figure3is avertical longitudinal sectional sections, one end section of the piston rod view taken on line 3-3 of Figure 2,;showing being connected to the piston and the other the removable brush head, the internally end section thereof being connected to an opthreaded tubular handle, the extensible piston crating head swiveled upon the innerend of rod for operating the piston and the operatthe tubular handle. The extensible piston f ing head for the piston rod with the piston rod is formed of a series of telescoping secrod in its fully extended position; tions 18, rectangular in end elevation, each Figure 4 is a sectional view, similar to Figsection comprising side walls flanged inwardme 3, showing the extensible piston rod in 1y at their lower ends as at 19 and flanged its fully retracted position; outwardly at their upper ends as at 20, the
' other end telescopes into said end section 18 of the piston rod and is flanged outwardly as at 23 for engagement with the outer flange 19 upon said piston rod section, the plug 21 being rectangular in cross section as illustrated in Figure 5.
The inner end section of the extensible piston rod is provided with an inner end wall 24 and said wall 24 has the inner end of a screw 25 fixed thereto as at 26, the screw freely extending through a central opening 27 provided in the inner end wall 11 of the tubular handle 10 and carried by an operating disk head 28 rotatably mounted upon the inner end of the tubular handle.
By rotating the operating head 28 in a counterclockwise direction, the piston 17 that is illustrated in its fully extended position in Figure 3 is threaded through the tubular handle to occupy a position adjacent the inner end wall 11 and during this movement, the sections 18 of the extensible piston rod telescope within each other as shown in Figure 4 and provide a relatively large chamber within the tubular handle between the piston 17 and brush head for the introduction of shaving cream or the like upon removalof the brush head from the open end of the tubular handle. Upon rotation of the operating head 28 in a clockwise direction, the piston 17 is threaded through the tubular handle toward the open end thereof for the discharge of the shaving cream onto the brush bristles 13, the extensible piston rod rotating with the operating head 28 and piston 17 with the rectangular form of piston rod sections providing positive drive connections between adjacent sections and eliminating any tendency toward binding of the parts and assuring perfect operation of the device.
While there is herein shown and described the preferred embodiment of the invention, it is nevertheless to be understood that minor changes may be made therein without departing from the spirit and scope of the invention as claimed.
I claim 1. In a fountain shaving brush, a tubular internally threaded handle having an open end, a brush head removably mounted in the open end, a piston threaded in the handle, a piston-rod for operating the piston formed of telescoping sections rectangular in end view and interlockingly connected together and an operating head for the piston rod mounted on the inner end of the handle.
2. In a fountain shaving brush, a tubular internally threaded handle having an open end, a brush head removably mounted in the open end, a piston threaded in the handle, a piston rod for operating the piston formed of telescoping sections rectangular in end view and interlockingly connected together, an operating head for the piston rod mounted on the inner end of the handle, and a plug connection between the piston and piston rod anchored to the piston and telescoping into the adjacent piston rod section and being nonrotatable relative to'said piston rod section.
3. In a fountain shaving brush, a tubular internally threaded handle having an open end, a brush head removably mounted in the open end, a piston threaded in the handle, a piston rod for operating the piston formed of telescoping sections rectangular in end view and interlockingly connected together, an operating head for the piston rod mounted on the inner end of the handle, a plug connection between the piston and piston rod anchored to the piston and telescoping into the adjacent pistonrod section, and said plug being rectangular in cross-section and non-rotatable relative to said piston rod section.
In testimony whereof I afiix my signature.
