E. E. TAYLOR SAFETY RAZOR July 7, 1936.

Filed Feb. 2, 1955 Patented July 7, 1936 PATENT OFFICE SAFETY RAZOR Earl E. Taylor, Lynn, Mass, assignor to Fannie E. Taylor, Lynn, Mass.

Application February 2, 1933, Serial No. 654,807

7 Claims.

This invention relates to safety razors and has for one of its objects to provide a handle portion so shaped as to facilitate presentation of the cutting edge of the razor in the proper 5. position for use.

A further object of the invention is to provide an improved means for securing the blade in position by which it will be securely retained when desired, but which can be readily -manipulated to free the blade and which is so constructed that it can be manipulated to clamp the blade only in the proper manner.

Further objects and advantages will appear from a more complete description of certain em.-

bcdiments of the invention shown in the accompanying drawing in which Figure 1 is a perspective of one form of razor in which this invention is embodied.

Figure 2 is a fragmentary central longitudinal section of the same but to a larger scale.

Figure 3 is a section on line 33 of Figure 2.

Figure 4 is a plan of the same.

Figure 5 is a side elevation showing a modification.

Figure 6 is an end elevation of the construction shown in Figure 5.

Figure 7 is a section on line ll of Figure 5.

Figure 8 is a perspective showing a further modification.

Referring first to- Figures 1 to 4, at 1 is shown a guard member presenting a plate portion against the outer face of which the blade 2 is clamped by a clamping member 3. To this end the guard I is provided with a pair of spaced openings at 4 through which may be passed tongues 5 struck from the material of the clamp 3. As shown the tongues 5 are laterally ofiset from the adjacent portions of the clamp in order to be passed through the openings 4 of the guard and engaged with the rear face of the guard adjacent to the openings 4. In order to insure a locking engagement between the parts, but which is readily releasable, the mating portions of the tongue 5 and the portion 6 of the guard member adjacent to one end of each of the openings 4 are formed concave and convex, respectively. In order that the guard member may not be incorrectly positioned end for end when in clamping engagement with the blade, the guard member at the opposite ends of the openings 4 is shown as provided with bent portions 1 so ofiset as to form barriers to prevent the passage of the tongues 5 into engagement with the rear face of the guard member at this end of each of the openings 4. The

clamping member is thus engaged in clamping relation to the guard member with the blade 2 therebetween by inserting the tongues through suitable openings in the blade and through openings 4 of the guard and then moving the clamp lengthwise to bring the tongue portions 5 into engagement with the portion 6 of the guard. As shown the clamping member 3 is formed of sheet metal having a central depression H) extending centrally between edge portions H which bear on the blade 2 somewhat back from its cutting edges [2. This depression It! acts to form stiffening ribs 13 extending parallel with the edges of the blade and these stiiTening ribs are connected by transverse ribs 55 spaced apart toward the central portion of the clamp 3 and inwardly of the tongues 5. These transverse ribs I4 define between them and between the ribs l3 a depression [5 (see Figure 4) which facilitates the engagement of the clamp by the finger or thumb in order to move it in blade-clamping or releasing directions.

In order to further facilitate the clamping and unclamping motions of the clamp member the body of the clamp member on opposite sides of the tongues 5 is provided with slots this in efiect increasing the effective lengths of the tongues and forming spring shanks therefor thus to increase their flexibility by reason of the increased length of the cut portions severed from the body of the clamp. The off-set portions of the tongues are preferably convexed in the same direction parallel to the face of the clamp on both tongues, as shown at 2!, in order to facilitate engagement of these tongues in round or square openings through the blade, as is shown and described in my application for patent Serial No. 552,829, filed July 24, 1931, for Safety razor (now Pat. No. 2,020,043). The clamp construction heretofore described may be employed to advantage in the razor having the marginal portions of its guard member extended to form handles as shown and claimed in my application Serial No. 552,829, and as shown in Figure 8. As shown the edges of the guard member 2 are bent inwardly to form edge bends 30 which are slotted to provide a comblike portion adjacent to the cutting edges l2 of the blade as is usual with safety razors.

The present invention also includes a special handle construction designed more particularly to facilitate the presentation of the blade-cutting edge to the face in the proper relation and where an extended handle portion for the razor is not objectionable. This handle may be formed as a separate piece and permanently secured in any suitable way to the guard member as by being riveted therein as shown at 3| in Figure 2, or if desired it may be formed up integrally from portions of the guard member as shown in Figures 5, 6 and '7. Referring to these figures, the edge portions of the guard member inwardly of the bends 30 are partly severed inwardly from opposite ends to leave a central unsevered portion 35 provided with lateral wing extensions 36 severed at their ends from the body portion of the guard. These wing portions 36 are then folded inwardly into substantially meeting relation, as shown in Figure '7, to form side walls of the handle member elements each substantially U-shaped in cross section and extending in parallel relation, the uncut portions 35 forming the edges of the handle. These handle portions are symmetrically related to the blade-supporting plate portion of the guard, so that either edge of the blade may be used with equal facility. This blade-supporting plate portion is transversely curved and the handle is arranged on its concave side. Preferably these Wing portions 36 are inclined inwardly so as to form finger-receiving depressions 38 on opposite sides and where the handle is formed solid as shown in Figures 1, 2 and 3, it is also preferably provided with similar finger-receiving depressions 39. These depressions 38 and 39 extend lengthwise of the handle and on side portions transverse to the edges of the blade and symmetrically related to both and when the fingers are engaged in these depressions the blade edge is conveniently presented to the skin in proper angular position for shaving.

From the foregoing description of certain embodiments of this invention, it should be evident to those skilled in the art that various changes and modifications might be made without departing from the spirit or scope of this invention as defined by the appended claims.

I claim:

1. A device of the class described, comprising a guard member of sheet material having parallel edge bends forming guards for the cutting edges of a double edge razor blade which may be secured thereto, the material of said guard beneath said bends being partly severed therefrom to form wing portions, said wing portions being turned inwardly toward each other into substantially meeting relation to form together finger engaging faces of a handle portion for said device.

2. In a device of the class described, a guard member having a pair of slots therein, a clamping member having a pair of tongues struck therefrom and extending in one direction lengthwise thereof and having their free end portions off-set to be passed through the slots of said guard member and engage the underface of said guard member adjacent to corresponding ends of said slots to clamp a blade against said guard member, said clamping member having slots extending away from said free end portions on opposite sides of said tongues to form between them spring shanks for said tongues to increase the flexibility thereof.
