SHAVING-BRUSH.

Specification of Letters Patent.

Patented Dec. 5, 1916.

Application filed February 9, 1916. Serial N o. 77,133.

T o all whom t may concern Be it known that I, FREDERICK W. Zuru- LER, a citizen of the United States, and a resident of Jersey City, county of Hudson, and State of New Jersey, have invented certain new and useful Improvements in Shaving-Brushes, of which the following is a specification.

The object of my invention is to afford a simple, compact, cheap and effective selfcontained and self-feeding shaving brush in which liquid soap is stored in convenient form for immediate use, as hereinafter more -fully set forth, the invention consisting in the specific construction and arrangement of parts described and claimed herein, distinctive features being the means for adjusting and regulating the discharge, as well as the means employed for delivering the liquid soap medially withinthe bristles of the brush.

ln the accompanying drawings, Figure 1, is an elevation upon an enlarged scale of my shaving brush; Fig. 2, is a central longitudinal sectional elevation of the brush showing the parts in their normal position; Fig. 3, a similar view showing the operative parts depressed for the delivery of the liquid soap to the brush bristles.

H, represents the hollow handle of the brush formed with the cylindrical pocket or chamber Inf-the main chamber' h', being of greater diameter, and of sufficient capacity to act as a reservoir for the supply of liquid soap s. The inner end of the handle H, is made cylindrical externally adjacent to the cylindrical ejection chamber L, for the purpose of receiving the ferrule f, in which the inner ends of the brush bristles b, are secured in a manner well known in the art. The end wall of the ejection chamber L, is formed with a nipple h2, having the axial duct 71,3, and upon this nipple h2, fits the inner end of the iexible tube d, preferably made of rubber and formed with a slit d, for the escape of the liquid soap under pressure,said slit d', closing automatically when the tube d, is relieved of internal pressure. The delivery tube d, extends well into the body of the bristles beyond the ferrule f, so as to deliver the liquid soap to the bristles in proximity to the free operative ends of the bristles. The delivery tube being thus flexible adapts itself readily to the manipulation of the bristles b, during the application of the latter without the least danger the piston p, being correspondingly femalescrew-threaded so as to engage therewith and be longitudinally adjustable thereon, as will be readily understood by reference particularly to Fig. 2.

On the outer end of the piston rod R, is

secured a push button r, and between this push button or head a, and the threaded portion of the rod the latter is formed with a cylindrical portion 1", of greater diameter than said threaded portion, thus forming an annular shoulder r2, against which rests the stop nut raf-said nut 113, in turn forming a shoulder to limit the inner thrust of the rod R, by contacting with the inner end of the hollow plug A, which screws into the outer end, of the handle H, a spring c, being interposed between the head or push button r, and the inner end wall of the plug A.

Obviously when the push button 1', is pressed inward against the resistance of the spring c, the piston p, will be forced into the cylindrical ejection chamber 7L, thereby displacing more or less of the liquid soap therefrom and ejecting it through the duct its, and delivery tube CZ, in among the bristles I), and the quantity thus ejected for use will be governed by the extent to which said piston y), protrudes into said ejection chamber L. Hence, it is apparent that the flow of liquid soap s, may be gaged and regulated by the adjustment of the piston p, longitudinally on the rod R.

When the push button fr, is released the spring e, returns the operative parts to their normal positions, and the slit cl, in the discharge tube d, automatically closes, thereby preventing drip or leakage, so that it will be seen that the flexible delivery tube d, with its discharge slitd, performs an important function in that it not only acts as an automatic discharge valve or vent but. also by its flexibility obviates any possibility of injury or discomfort to the skin to which the lather is applied.

In order to render the slit al', at the outer end of the discharge tube d, more effective in sealing said tube in the absence of an excess of internal pressure therein, I thicken i position, and the piston p, rod R, and screw plug A, are then replaced. y

It will be noted that externally my brush diders little if any in appearance from the ordinary shavin brush; and its internal construction an arrangement of parts is so simple and effective as to require little or no attention, While by removing the plug A, rod R, and piston p, as above set forth the parts may be readily cleansed andv Washed out as desired.

l have herein described the discharge tube d, as made of unvulcanized rubber, which is obviously ay preferable material, although the essentials of the discharge tube are that it shall combine flexibility and elasticity 25 with resilience, for reasons hereinbefore stated.

What I claim as my invention .and desire to secure by Letters Patent is,

A shaving brush of the character desig- 30 nated, comprising a hollow reservoir handle formed with a contracted cylindrical ejection' chamber communicating with a flexible elastic resilient discharge tube .protruding among the brush bristles, said flexible elastic resilient` discharge tube vbeing slitted at its outer extremity the edges ofthe sli/t being made in the form of flat contacting lips of greater Width and thick' ness than the Walls of the tubek for the purpose set forth, and a spring push rod formed 'with a piston fitting into said cylindrical ejection chamber.
