Patented Nov. i 20, 1945 UNITED STATES PATENT .orrlcE SAFETY RAzoR George E, 'Traynham, Wilkes-Barre, Pa. Application November 21, 1 944, serial No. 564,519V

4 Claims. ,('CL 30-41l The device forming the ,subject matter of this application is a safety razor vcomprising ,a `receptacle for lather. One object o f the rinvention is to reinforce the receptacle across its open end or mouth, and to use a guard for that purpose, the guard being so mounted on the receptacle that .the guard may be Aopened to facilitate a cleaning of the receptacle.

Another object of the invention is so to construct the guard and associated parts that lather will nd its way readily into the receptacle-` A further object of the invention is so to connect the guard with the receptacle that a proper registration and vcooperation between associated parts will .be afforded.

`A mechanic who abides .by what is yclaimed may make such changes-as his skill may direct, without departing from the spirit of the invention.

In the accompanying drawing:

Figure 1 shows, in longitudinal section, a safety razor embodying the invention, parts remaining in elevation.

Figure 2 is a transverse section.

Figure 3 is a top plan of guard and parts below it.

The safety razor forming the subject matter of this application comprises an elongated tubular handle I, wherein is journaled a shaft 2. A turning button 3 is secured to the lower end of the shaft 2. At its upper end the shaft 2 carries a fixed, upwardly tapered head 4. The head 4 and the turning button 3 cooperate with opposite ends of the handle I, to hold the shaft 2 in place for rotation, but against longitudinal movement. The head 4 is supplied, in its upper end, with an axial threaded bore 5.

The letter R marks a horizontally elongated lather receptacle. The lather1 receptacle R comprises a bottom 6, side walls 3, and end Walls 9, the side walls and the end walls converging downwardly toward the handle I. of the receptacle R is secured to the handle i, a little way below the upper end of the handle. rihe wear imposed by the head 4, therefore, comes on the end of the handle I and not on the bottom 6 of the receptacle.

At the present time, owing to war conditions, no iine lines, of course, as to structural material are possible. It is necessary to use whatever materials may be available. Therefore, the open top lather receptacle R may be made of such material that the bottom 6 may not be well adapted to withstand wear imposed by the head The bottom 6 v 4. lIn the present invention, the head 4 .does not engage the bottom 6 vof the receptacle R.

A guard IB is superposed on the receptacleR.

A hinge Il connects one end of the guard Ill with one end wall 9 of the receptacle R, for open.-

ing and .closing movement.

In the .opposite end of the guard ID there isa notch I4, adapted to receive a resilient latchI2, connected to the corresponding end wall 3 of the receptacle R, the construction being such that lthe guard Ill may be held releasa-bly in closed position with respect to the receptacle.

Near its longitudinal `edges the guard i8 is provided with elongated slots I5, disposed .directly above the side walls 8 of the receptacle R and close to the edges thereof. The guard I0 is Supplied with spaced holes I, and withan inter.- mediate kopening.; Il. A blade 18 is fmounted ,on the guard lll. y I

The numeral` I9 designates a transversely curved cap, provided intermediate its ends with a depending stud 20, extended through the intermediate opening I'I of the guard l0, and received in the threaded bore 5 of the head 4 of the shaft 2, a releasable threaded connection between the stud and the shaft thus being afforded. The cap is supplied with short, depending fingers 2I, engaged in the holes I6 of the guard I3.

The hinge I I constitutes means whereby, when the guard IIl is closed, the opening I1 in the guard will be alined with the axis of the shaft 2, to admit the stud 20 and permit the threaded connection between the stud and the head 4 of the shaft 2 to function. The slots I5 of the guard I0, moreover, are positioned properly with respect to the receptacle R and to the side walls 8 thereof.

The releasable latch connection formed by the part I2 and the notch I4 position the guard I0 properly with respect to the receptacle R, should the hinge connection II become slightly loose.

It has been alleged hereinbefore that the receptacle R need not be made of strong material, and that necessity may compel the use of a ma-l terial which, otherwise, would not be employed. The receptacle R may be formed of such material that it needs reinforcement across its open top. The hingedly mounted and latch-held guard IIl enables the guard I0 to form the necessary reinforcement for the receptacle R across its upper end or mouth.

It will be observed that the end walls 9 of the receptacle R are higher than the side walls 8 thereof, to define lather-admission openings 22 below the longitudinal edges of the guard I0.

The utility of the device will be apparent from a casual inspection of the Figure 2. Lather collected on either longitudinal, outer edge of the guard I0, will enter the receptacle R by way of the openings 22. Lather which passes underneath the blade I8 will nd its way into the receptacle R by way of the slots I in the guard l0.

The lather is collected in the receptacle R with obviously desirable results.' The guard I 0 may be opened on its hinge II to facilitate a cleaning out of the receptacle. When the guard I0 is in closed position depicted in Figure 1, the receptacle R is reinforced along its upper end or mouth.

What is claimed:

1. A safety razor comprising a tubular handle, a lather receptacle mounted on the upper end of the handle, a shaft journaled in the handle, a

guard superposed on the receptacle and having an intermediate opening, the guard being provided near one of its longitudinal edges with an elongated slot disposed directly above the receptacle and close to one edge thereof, a cap superposed on the guard, a depending stud carried by the cap and extended through the opening, a releasable threaded connection between the stud and the shaft, and a hinge uniting one end of the guard with one end of the receptacle, the hinge constituting means whereby, when the guard is closed, the opening will be alined with the axis of the shaft to admit the stud and permit the threaded connection to function, and whereby the slot will be disposed in the position stated.

2. The safety razor of claim 1, in combination with a releasable latch connection between the opposite end of the guard and the corresponding end of the receptacle, to position the opening and the slot as specified in claim 1, should the hinge wear loose, the guard forming a reenforcing connection extended across the upper end of the receptacle.

3. A safety razor comprising a tubular handle, a lather receptacle mounted on the upper end of the handle and comprising side walls and end walls, a guard superposed on the receptacle and having an intermediate opening, the guard being provided near each of its longitudinal edges with an elongated slot disposed directly above the receptacle and close to one edge thereof, a cap superposed on the guard, a depending stud carried by the cap and extended through the opening, a releasable threaded connection between the stud and the shaft, and a hinge uniting one end of the guard with one end of the receptacle, the hinge constituting means whereby, when the guard is closed, the opening will be alined with the axis of the shaft, to admit the stud and permit the threaded connection to function, and whereby the slots will be disposed in the positions stated, the end walls of the receptacle being higher than the side walls thereof, to define lather-admission openings below the longitudinal edges of the guard.

4. A safety razor comprising a handle, an opentopped lather receptacle secured to the upper portion of the handle and made of such material that the receptacle needs reenforcement across its open top, a guard hinged to one end of the receptacle, whereby the guard may be opened to facilitate a cleaning of the receptacle, a releasable latch connection between the guard and the opposite end of the receptacle, whereby the guard will form the aforesaid reenforcernent, a cap superposed on the guard, and means for moving the cap to blade-gripping relation with respect to the guard.
