SAFETY-RAZOR. 1

To all whom it may concern:

Be it known that :I, ELLswoRTH L. Mo-

CAIN, a citizen of the United States of America, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Safety-Razors, of which. the fol lowing is a specification, reference being had therein to the accompanying drawings.

This invention relates to safety razors, and the primary object of my invention 1s to provide a razor consistin of comparatively few parts that can be easily and qu1ckly as sembled, maintained in a sanitary condit on, permit the user to position the blade of the razor in a convenient position for shaving, and permit of a double edge blade being used so that if one edge of the blade is not sharp the blade holder may be positioned to present a sharpened edge of the'blade for shaving purposes.

A further object of my invention is to provide a safety razor embodying a handle having resilient members adapted for connecting a blade holder and blade relative to the handle so that the blade holder and blade may be quickly assembled and safely used, the handle having means so that the resilient members thereof can be locked relative to the blade holder and .blade to prevent accidental displacement of these parts durin use. i The above are a, few of the objects at- .tained by my invention, and reference will now be had to the drawing, wherein- Figure 1 is a front elevation of a safety razor;

Fig. 2 is a vertical sectional view of the same;

Application filed March2, 1917. Serial No. 152,108.

The handle of the razor is preferably made of a strip of metal bent intermediate the ends thereof to provide substantially parallel members and said members are connected by. a transverse rivet or pin 2, thereby providing a rigid handle portion 3 between the rivet 2 and the bent or looped end of the handle. The members 1 have the upper ends thereof sprung outwardly and these members ossess a degree of resiliency, somewhat similhr to tweezers, so that said members may be sprung toward each other. The members slightly taper from the lower end of the handle to the upper end thereof and the upper ends of said members are provided with heads 4 and opposed slots 5, the opposed slots providing neck portions 6 be tween the heads 4 and the members 1. The

heads 4 are in the same plane as the members l and the upper ends of said members are slightly curved so that the longitudinal axes of the heads 4. will be in an angle to the members 1, and this is best noted in Fig. 2.

Pivoted on the rivets 2 of the handle is a barrel 7 of a lock member 8. The upper end of said lock member terminates in a hook portion 9 and a bill or finger piece 10. The upper end of the locking member is adapted to swing between the members 1 and its closing movement is limited by side lugs 11 on said member and adapted to impinge against side edges of the members 1. The opening movement of the lock memher is limited by protuberances on the inner side of the members 1.

The reference numeral 13 denotes a blade at the ends of the slot 17 there are struck up lugs 18 and at the ends of the slot 16 are protuberances 19.

The reference numeral 20 denotes a blade having side cutting edges 21 and intermediate the ends of said blade there are intersecting or communicating slots 22"and 23 similar to and adapted for registration with the slots 16 and 17 of the blade holder 13. The longitudinally disposed slot 23 is slightlylonger than the slot 17 of the blade I holder, so that the ends of the slot 23 may receive the upstanding lugs 18 and permit alternately resting on the teeth 19 and the longitudinal-seat 14,'as best shown in Fig. 2.

With the blade and blade holder assembled, and the locking member 8 of the handle in an open'position, the upper ends of the members 1 may be pressed toward each, other until the heads 4 practically contact,

then said heads can be inserted in the slots 16 and 22 and the members 1 released so the slot-117 of the blade holder and in so of the heads 4 and the blades will be maintained evenly and properly seated upon the doing force the blade 20 against the head 4 and the blade holder against the lower face of the blade. The teeth 19 and the seats 14: will prevent the blade 20 from being unduly flexed by contact with the .ends

blade holder.

The razor is now ready for use with the blade disposed at a slight angle to the longitudinal axis of the handle and when it is desired to disassemble the parts it is only necessary to press upon the bill or finger piece 10 of the locking member to swing said member to an open position, compress the members 1' and then remove the heads 4 from the slots 16 and 22. The shape of the slots also permits of the neck portions 6 of the members 1 being placed in the ends of the slots 16 and 22,. thereby positioning the blade holder and blades as shown in Fig. [7, and this position of the razor blade may be more convenient to the user than the positionshcwn-in Figs. 1 and 2.

It will be noted that the blade 20 is reversible and that either edge thereof -may be used. As showing a single edge razor, see Figs. 8 and 9. The blade holder is designated 25 and has one end thereof toothed to provide a guard 26 and the opposite end thereof flanged, as at 27, to provide aback railfor a blade 28 having a single cutting edge 29. The holder 25 and the blade 28 have longitudinal slots 30 and31 respec-' tively adapted for registration when the blade 28 is positioned on the holder 25. The handle shown in Fig. 6 may be used by pressing the heads 4 together, inserting the heads through the slots 30 and 31, and then turning the handle a quarter of a revolution so that the neck portions 6 may engage in the ends of the slots 30 and 31. With the locking member 8 between the members 1,, the blade holder 25 and the blade 28 thereof can be firmly held for shaving purposes.

In Fig. 10 is a blade 32 having a double edge and a single longitudinal slot 33, and a blade holder may-be provided for the blade so as, to be held by a handle in -a manner similar to the blade 28 and holder 25.

The preferred'embodiments of my invention have been illustrated and it is to be understood-that the structural elements are susceptible to such variations and modifications as fall" within the scope of the appended claims.
