FOUNTAIN SHAVING-BRUSH.

Specification of Letters Patent.

Patented Nov. 5, 1907.

Application filed J 11y 16, 1906. Serial No. 326,347-

To all whom it may concern:

Be it known that I, IRVING D. STEvENs, a citizen of the United States, residing at Chicago, in the county I of Cook and State of Illinois, have invented certain new and useful Improvements in Fountain Shaving- Brushes, of which the following is a specification.

My invention relates to fountain shaving brushes in which the brush is constructed with a hollow handle forming a reservoir for containing liquid soap or shaving cream, and means for discharging the liquid soap from the reservoir into the brush properwhich is secured at one end of the hollow handle.

In a fountain shaving brush characterized by my invention, the liquid soap is caused to pass from the reservoir into the brush proper by means of a spiral conveyer arranged within a tube which extends from the reservoir into the brush, or more specifically defined, into the bristle portion of the brush. The spiral conveyeris at one end of a rotary screw rod arranged to engage'a nut. This nut is confined within the reservoir and forms a follower which forces the liquid In the accompanying drawing: Figure 1 is a longitudinal central section through a fountain shaving brush involving my invention, the rod having the conveyer screw at one end being shown in elevation. Fig. 2* is a transverse section on line z-a: in Fig. 1.

The brush handle A is made hollow so as to form a a reservoir 1, which contains a body of liquid soap.

The brush handle is provided at one end with a socket 2, and the brush head or butt end portion of the brush or body of bristles B is secured within said socket.

-The hollow handle is also provided at its end wall 3 conveyer.

with a nipple 4 which projects into the brush head, and a short tube 5 forming a discharge nozzle is fitted and secured at one end portion in the nipple 4 and adapted and arranged to extend forward into the brush or body of bristles B, so as to form a duct through which liquid soap is conveyed from the hollow handle into the brush bristles. p

G indicates an axially revoluble rod arranged centrally and longitudinally within the hollow brush handle and provided at one end with a double spiral screw 6, which extends into and through the tubular discharge nozzle 5 where it is designed to operate as a The major portion 7 of the rod back of its screw portion 6 is threaded and extended through a centrally arranged threaded opening "in a nut or disk 8, which operates within the hollow handle as a follower when the rod is axially rotated. In order to hold this follower 8 against rotation while it is being moved along the bore of the hollow handle, it is provided with oppositely arranged peripheral notches which receive longitudinal guide ribs 9 provided along the inner side of the hollow handle. The rod 0 is provided with an annular flange or collar 10 which forms a washer, and back of said flange or Ic'ollar it is provided with a smooth portion 11 which. extends through and turns within a bearing provided by a screw cap D on the butt end of the hollow handle. The cap D is removably screwed on a threaded end portion'of the handle, and the rod is provided at its outer end with a milled knob 12 so that it can be readily. taken hold of and operated. I

When it is desired to refill the hollow handle or to tity of liquid soap, and the rod or stem 0 is axially I rotated,'th e rotation of the screw conveyer portion 6 V of said rod within the tube 5 will convey liquid soap from the hollow handle into the brush B, and synchronously with this conveying action of the conveyer portion 6 of the rod, the rotation of the rod will move the follower 8 toward the forward end of the brush, 4

thereby keeping filled the portion of the reservoir in which a part of the screw conveyer 6 is exposed, and also tending to force the liquid soap into the conveyer and thereby operating as an auxiliary thereto. When however the rod .0 which also forms a screw for operating the longitudinally movable nut plate: and a double bladed screw conveyer 6 arrangedto operate within the discharge nozzle 5, is inactive, the double bladed conveyer portion 6 serves to prevent outflow of liquid soap through the discharge nozzle.

What I claim as my invention is:

1. In a fountain shaving brush, a hollow handle forming a reservoir for liquid'soap and having a discharge nozzle projecting within the bristle portion of the, brush, in combination with means for ejecting liquid soap from the reservoir into the bristle portion ofthe brush byway of said discharge nozzle and consisting of a rotary rod arranged centrally within the handle and having aspirally bladed end portion operative within the discharge nozzle for conveying and forcing liquid soap from the reservoir into the bristle portion, and a non-rotary nut or plunger fitted with in the reservoir and also fitted as a nut on a threaded portion of the rotary rod, which letter when rotated in one direction propels the plunger plate toward the point of discharge synchronously with and as an auxiliary to the ejecting action of'its spiral bladed portion.

2. In a fountain shaving brush, a hollow handle forming :1 reservoir for liquid soap and having a discharge nozzle projecting within the bristle portion of the brush, in combination with means for ejecting liquid soap from the reservoir into the bristle portion of the brush by way of said discharge nozzle and consisting of a rotary rod arranged centrally within the handle and having a double spirally bladed end portion operative within the discharge nozzle for conveying and forcing liquid soap'from the reservoir into the bristle portion, and a non-rotary not or plunger fitted within the reservoir and also fitted as a nut -on a threaded portion of the rotary rod, which latter when ro tated in one direction propels the plunger plate toward the point of discharge synchronously with and as an auxiliary to the ejecting action of its spiral bladed portion.
