Jan. 28, 19%. c. F] ERN zmzmw RAZOR ATTACHMENT Filed Dec. 9, 1933 INVENTQR ATTORNEY Patented Jan. 28, 1936 UNITED STATES PATENT OFFICE 8 Claims.

This invention relates to an attachment for razor blades and more particularly to a spring attachment or safety device for application to the blade of a straight razor.

One object .of the present invention is to provide a spring clip with a guard device adapted to serve as a handle for manipulating the spring when applying or removing the attachment to or from the razor blade.

Another object of my invention is to provide a guide device to facilitate the application of the razor blade, at the proper cutting angle, to the surface being shaved.

Still another object is to provide an attachment having two hinged members, each of which may serve either as a guide or as a guard, and both of which serve as a handle for manpulating the spring in applying or removing the attach.- ment, and whereby the attachment may be held open to facilitate convenient and thorough cleaning by exposure of the internal parts.

With these and other obiects in view, my inyention consists in the particular construction .and arrangement of parts constituting my novel razor attachment, hereinafter described and illustrated in the accompanying drawing, and particularly pointed out in the appended claims, it being understood that various changes may be :made without departing from the spirit of the invention or sacrificing any of the advantages thereof.

In the drawing, Fig. 1 is a perspective view showing an ordinary razor blade with my improved attachment applied thereto and in position for shaving;

Fig. 2 is an enlarged cross-section taken on the line 2-2 of Fig. 1;

Fig. 3 is a side View of the spring;

Fig. 4 is a View looking on the outer face of one of the guards or guide members; and,

Fig. 5 is an end view of a razor blade showing the attachment partly in section and in position for application to or removal from such blade.

My improved attachment comprises a spring device 6 of thin sheet steel or other suitable material made in the form of a saddle with a doubled-over portion 20 adapted to engage the back of the razor blade and with lower edges 1 adapted to normally engage closing against the sides of the razor blade 8 when the attachment is in use on the razor, the said'edges l lying parallel to, and at a little distance from, the cutting edge 9 of the razor. Each side of the saddle shaped spring 6 is formed with a slot [0 having a recess II at its center, and having at each side of said recess II a rolled portion l2 forming a sleeve and each of the two hinged guard or guide members I3|4 is formed at one edge with teeth l5 as usually provided on the guards of safety razors. The opposite edge of each of said members is 5 formed with a central projection iii to be accommodated in the recess l l in the spring, while two slots H are provided for the accommodation of the rolled over portions i2 of the spring so as to provide a hinge for each of the two members l3, IA.

The central projection 16 is provided with a face l8 (Fig. 4) for engagement with the side of the razor blade when the member is in the position shown at I l Fig. 2, and on the opposite side of the member IS a similar face 2| (Fig. 1) is provided for engagement with the side of the razor blade when the hinged member is in the position shown at 13, Fig. 2, and the action of the spring 6 is such that the members [3, M are 20 effectively held in these two positions. In the position shown at Fig. 2 the member'l3 serves as a safety guard while the member l4 serves as a guide to ensure that the blade 8 properly held at the correct cutting angle to the surface indicated by the dot-and-dash line 19.

It should also be understood that the member M Fig. 2 may be moved into position to serve as a safety guard, while the member 13 may be raised away from the razor blade to serve as a guide so that the razor may be conveniently adapted for either right or left hand shavin and both members l3, l4 may be folded at the same time against the blade as when the razor is not in use, or both members may be turned up away from the blade, i. e., both members may be brought into the position of the member M in Fig. 2, to facilitate opening of the saddle spring 6, which opening is effected by pressing togetheras shown at Fig. 5--the free edges of the members l3, l4, so that the side edges of the doubled-over portion 20 of the spring 6 serve as fulcrurns and permit of the edges 1 being swung apart against the spring action, so as to release the blade 8.

Although the drawing and the above specification disclose the best mode in which I have contemplated embodying my invention, I desire to be in no way limited to the details of such disclosure for, in the further practical application of my invention, many changes in the constructional details of the attachment may be made as circumstances require or experience suggests, without departing from the spirit of the invention within the scope of the appended claims.

2 What I claim is:

1. A razor blade attachment comprising a spring for engaging the blade, hinged means to serve as a guard for the cutting edge of the razor blade and as a handle to manipulate the spring to apply the attachment to or remove it from the blade, and faces on said means for directly engaging the blade to retain said means in different positions.

2. A razor bladeattachment comprising a sad- 1 dle spring to grip the blade, a pair of hinged engaging the razor blade to hold the flaps in position to serve-as a guard for the cutting edge of the razor andas a guide to ensure the correct cutting angle, and fulcrummeans adapted to be engaged by the flaps to open the spring when the said flaps are moved towards each other from their guarding position.

4. A razor blade attachment comprising a spring to-grip the blade near its cutting edge,

sleeve parts on said spring, a pair of hinged members carried by said sleeve parts, means on said members for engaging the razor blade and retaining the hinged members in position to serve 'as' a'safety guard and also in position to serve as a'guide to ensure the correct cutting angle of the razor, and fulcrum means for engagement by said hinged members whereby the spring is opened by movement of the guards towards each other at the'back of the razor blade.

'5."A razor blade attachment comprising a spring having a doubled-over portion to engage the back of the blade, a member on one side of the attachment to serve as a safety guard for the cutting edge of the razor blade, as'a guide for the razor and as'a fulcrumed handle to spread the spring to apply'the attachment to or remove uard members are moved towards each otherat the back of the razor blade. e

6. A razor blade attachment comprising a saddle spring, a pair of hinged flapsfor spreading the spring to release the razor, and means for holding the flaps in position to serve as a guard for the cutting edge of the razor and as a guide to ensure the correct cutting angle, said means including a projection formed on each flap and two side faces formed on the projection to engage the side of the razor blade when the flap is in said positions. g V

'7. A razor blade attachment comprising a saddle spring with edges engaging.thesidesofthe blade, two hinged membersto serve as a safety guard for the cutting .edgeof the razor blade,

means for pivotally connecting said members ;to the spring along lines .remote'fromthe razorengaging edges of .the spring, and fulcrum means for engagement by the .hinged members and whereby movement of. said members. towardseach other adjacent to the rear edge of thebladeserves to open the spring to apply the. attachment. or to remove it from the blade.

8. A razor blade attachment. comprising a-saddle spring with edges closely engagingthe sides of the blade, a pair of hinged 'fiaps for spreading the spring to release the razor, means. for pivotally connecting each flap to the spring;along .a line remote from the blade-engaging-edge of the spring, means on said flaps for holding them. in position to serve as a guard for the cutting edge of the razor and as aguide to ensure the'correct cutting angle, and meansfor limiting :the movement of said flaps relatively to the spring. whereby spreading of the spring is causedby movement of said flaps towards each otheradjacent to .the back of the blade; 7
