Patented Aug. 17, 1948 NITED -S TATES T HY' EIYL AZ B William Neuburge r, Appacatmn November. 21, 1944, Serial No. 564,429 40mins. (case- 41) This invention relates to fountain safety razors and is herein described in some detail as embodied in a safety razor, using a standard commercial type of blade, that has a ehamber in which pressure on contained soap or soap solution is maintained after pumping in air above it. '-Attemptshave been made'to produce fountainsafety razorsbut no one of these have proved successful commercially. V

-The nozzles were set at a fixed angle and so were not well adapted to usevarying typesor varying of soap or other solution.

In most cases no steady flow of solution to the blade could be counted on.

Some razors lacked proper devices to produce an even flow of soap solution. Others used feeding devices which were supposed to break up the flow but actually interfered with the flow, other razors proved unsatisfactory in many other ways.

According to the present invention the foregoing and other objections and difiiculties are overcome and a razor is provided in which airpressure feeds the soap solution through nozzles near the blade and those nozzles can be individually adjusted by the user to suit his own ideas of efllciency.

Once set, the supply of soap in the chamber provides predictable shaving conditions for several days.

Other features and advantages will hereinafter appear.

Fig. 1 is a side view largely in section, of a razor embodying the present invention.

Fig. 2 is a sectional side view taken on the central line of Fig. 1.

Fig. 3 is a sectional side view of a delivery valve or nozzle. 7

The razor shown in Fig. 1 includes a cylindrical bairrel l having an extension ll beyond the barre The barrel I0 is adapted to be filled with soap solution or other shaving preparation through a side valve I 2 which is shown as including a body l3 having a bore I4 and annular cap IS.

The solution is adapted to be put in through the central opening l6 of the cap I by forcing the solution with an atomizer or otherwise to push back a ball I! which normally closes the opening Hi to admit the liquid.

When liquid is no longer forced in a spring l8 shifts the ball I! to close the opening IS.

The razor is then adapted to deliver soap solution through the two end nozzles l9. They deliver each behind the usual blade 20 and in the form shown the nozzles l9 stand about one-third of the distance from the center of the blade to his own ideas.

its end.

' To do this delivering the razor is shownashaving' a plunger 2| with a stem 22- extending out beyond the annular cap 23 which closes the end of the extension I l When the stem-22 is pressed it forces its plunger 21 down in the extension H to compress air within the extension and force the air through a valve 25 in the partition 26 which forms the bottom of-the extension I l.

7 The valve 25 may be like the valve-"i2 and either of them may be either screwed or sweated into place.

The nozzles l9 may be clear for some types of soap solution so that they deliver mixed air and solution freely. For some types of solution the nozzles I! may be constructed as shown in Fig. 3 in which a stem 21 carries a head 28 which forms more than half of a sphere and embraces a hemispherical end head 29 so that the end head 29 can be diverted toa wide variety of angles and cause its central opening 30 to deliver soap or soap and air at any desired angle to the blade.

In the form shown the opening 3| in the stem 21, which is the effective nozzle is normally closed by a ball 32 held against it by a spring 33 which bears against the inner-surface of the head 29.

The ball 32 is adapted to hold within the barrel l0; any contained liquid but to be displaced by air pressure and deliver liquid through the open- .ing 30 either in a stream or drops 01' foam.

The razor bade 20 is shown mounted in one of the standard forms as held on a post 35 by over-lying the curved member 36 which carries the usual guard teeth 31 and is held against the member 36 by the usual holding piece 33 which is threaded at 39 so that the threaded end 40 of the post 35 when screwed down on the threaded end 39 draws on the piece 38 to firmly bend the blade 20 and hold it in place for shaving, because the curved member 36 seats on the shelf M on the post 35 where the thread 4!] begins.

In the form shown the nozzles I!) are short enough to enable them to stand clear of the guard member 36 when the razor body is turned to tighten the holding piece 36.

The user of the razor after trying it and finding it unsatisfactory can remove the blade and the guard piece 36 and alter the angle at which the opening 30 delivers the soap solution to suit An opening 42 in the extension I l to the front of the piston 24.

admits air 7 The razor body is well out of plastic material but in some detail as adapted to be metal.

To this end the cap adapted to be molded is herein described also made of 23 is shown as threaded at 39 on the end of the extension II, the end nozzles H! are shown on an end plate 40 which is threaded into the end of the bar-rel I0, and the partition 26 is shown as forced onto small slanting raises'fdl gin 'jhGAjIIfCQ'IlOI ofth barrel I;

If the-plunger admit air behind the retreating plunger may be added.

By unscrewing the end plate 40, thednterior is easily washed out and the valves 49 form easily grasped handles for turning the plate Ju ta-re lease it.
