SAFETY RAZOR.

` Application led August 25, 1921. Serial No; 495,218.A

(GRANTED UNDER THE PROVISIONS F THE ACT 0F MARGH 3, 1921, 41 STAT L., 1213.)

To all whom t may concer/n.'

Be it known that I, MAME-Louis Riviiinn, a citizen of the French Republic, and `residing in Faris, France, 16 Boulevardvde Strasbourg, have invented certain new7 and useful improvementsv in and Relating to Safety Razors (for which l have obtained patents in France` first patent of Addition No. 19,871, dated April 28, 1914, and second patent of Addition No. 20,048, July 8, 1914),

of which the following is a complete specification.

This invention relates to a safety razor of the kind in which the blade can be pressed down into the plane of the handle so as to occupy as little a space as possible.

One object of the invention is to enable the blade to turn on its blade-carrier with- 4 out necessitating the blade being seized Aby the ngers, thereby obviatingl all danger of being cut.

Another object is to enable the blade to turn without necessitatingy a complicated construction of the razor, and to mount the said blade upon its handle in such a way that the distance between the blade and the safety comb may be varied at will.

In the annexed drawings which show as an example a razor according to one embodiment of the invention,

Fig. 1 shows the razor closed.

Fig. 2 shows the razor in the opened position.

Fig. 3 shows the said razor in its comg pletely unfolded position.

Fig. 4 is a perspective view showing-the .blade infposition of use.

Figs. 5 and 6 represent the said blade in the positions for cleaning and stropping reH 4U spectively.

Fig. 7 is a detail view.

Fig. 8 is a side view of a modified constructional form of the razor. y

Fig. 9 is a vertical section of Fig. 8.

Fig. 10 is a plan of the blade and of its comb, viewed from the underside, the said Figs. Sto 10 being drawn on an enlarged scale.

The blade of the razor is mounted by means of a spindle b upon a head o, which is in two parts c, c', assembled by a pivot around which the part c can swing in order to take up the positions shown in Figs. 2

and 4. A spring suitably arranged and not shown on the drawings retains the part c firmly in the two positions.

The head c, c is mounted upon a support e provided at its base withtrunnions f supporte'dat the extremities of arms g provided at one end of the hollow handle l1, ofthe razor. of such form that for the folded position of the device shownin Fig. 1 the head c is accommodated entirely within the handle thereby reducing the amount of space taken up by the whole.

A safety comb z' is pivoted upon the support e and is provided with avspring y intended to retain it in closed position (Figs, 1 to 3 and 6) and in position for use (Fig.

if: (Fig. 7 mounted in a chamber in the support c, and which is terminated at its free extremity in a press-button m. A spring n tends constantly to urge the button m into notches o formed in the wall of the support e and corresponding to the positions of use and of cleaning of the blade respectively.

For using the razorA when it is in the The hollow formed in this handle is d,

Thel head o c is mounted upon a spindle folded position shown in Fig. 1, the head c is'pushedin such a manner as to make the whole of the head and support e pivot aroundthe trunnions f (Fig. 2.) When the support e is in the plane of the handle 7L, it can be maintained in position notl only by the elasticity of the arms g but also by an abutment p which may, for example, abut against inclined surfaces provided upon the extremities of the arms g.

To strop the blade before use, the members occupying the position shown in Fig. 3, the blade is swung around its pivot b to the position shown in Fig. 6. It isthen possible to sharpen the blade on the strop or any other material without having to take in order.` to, facilitate the cleaning. (as the Vlatherfsticks rather closely tothe blade and 'comb), the blade is turned round into the .-pesitian Shawn in Eig- 5,.,bysrer1y-pushins the'l iittn in the direction. of the'ar'row in` Fig. 4. After cleaning the blade and wiping it sufficiently, the members are brought. back into the position shown in ,F ig. 1, and the razor can then be shutA upin a casetaking up a very small amount of room.

The blade can be fittedy in any suitable.

'Ehe said projection r is o'r' i iin'length less `than the openingg of the blade, which thus allows the blade to be displaced inthe directionofthe lengthofthe said opening," thus compensatingv the wear offthe" blad'causedby the several strop? In the constructional form of Figs. 8 to l0, thesafety col'nb, instead of being solid 'with the headV c, ismounted upon a spindle s upon which: itisablle to. oscillate, and

Owingu to thesaidgarrangemenn when the razor isfusedw-ith'a View to shave oneselll 'very closely, the leverisacted upon in orderto rotate in theconvenient direction the body o. The groove-uct the said body onrotating in front off the pin t offthe comb gcauses the-saidpin to-,be raised or lowered, Vwhich corresponds to a, displacement of the Vcomb itself, either-awayfrom the blade, or

' f' towards the said blade. It is -thus easy, be-

fore using thefrazor, to controlA the distance betweenthe blade and the comb, accordingl that one desires torbe shaved-1 more or less closely.

Should vthe blade, afterA having been stropped lseveraltimes, have become shorter, the^ nut1 z,wh.ich-reta ins the blade in its position is firs t loosened, then the said blade is displaced into the direction of the arrow in Fig. l0, in order to conveniently determine the distance between the extreme edge of the comb and the edge of the blade. V""or cleaning the razor after use, the lather may be washed away after having brought the said blade into the position shown in Fig. 5, by depressing the tail y of the blade. The blade is then brought back to its normal position by simply pressing. the tail y with the thumb. The blade may be at will rotated towards the right or towards the left;

It is obvious that the shape of the severalparts ofl the razor may be varied at will. The displacements of the comb could be obtained by inversing the arrangement of the corresponding parts, the piu t being helicoidal in shape and being guided between ribs forming a guiding Way for the projection of the comb.

`What I claim is:

1. In a razor, a blade, a handle comprising a'substantially open frame, and mounting means connected tothe blade and to the handle and adapted to be extended from the handle to position the blade vfor operation o r to be folded into the space within the handle with the blade folded thereagainst.

2. In a. razor, a blade, a handle comprisinga. substantially open frame, and mounting means connected to the blade and to the handle and adapted to be extended from the handleto position the blade for operation or to be folded into the space within the handle with the blade folded thereagainst, said` mounting means comprising a support pivotally connected to the frame. a head having` a p art carried by the support and a swingable part pivotally con n'ected tothe part carried by thehead and means for rotatably mounting the blade on the swingable part of the head.

3. In av razor, a blade, mounting means for the blade including a head, the blade being mounted for longitudinal adjustment on the head, a swingable guard cooperable withthe blade, and means tor swinging said guard toward or away from the frame.

4. I n a razor, a blade, mounting means for thetblade including a head. a sui'ingabh-n guard cooperable with the blade, and means for swinging said guard' toward or away from the frame, andV comprising a circula-r body having an operating handle and provided ivith a helicoidal groove. said guard having a pin operatively received in the helicoidal groove.

In testimony I have hereunto set my hand at Paris, France, this 10th day of August, 1921.
