My invention relates to safety razors, and its primary purpose is to provide a safety razor frame adapted for using a single safety razor blade over relatively long periods of time by providing means associated with the frame for securely holding the blade in position for conditioning, as by stropping and/or honing.

A further object of my invention consists in so constructing the safety razor frame that it may be encompassed within small space and that it may be used over relatively long periods with practical freedom from mechanical and operating annoyances.

A still further object of my invention consists in providing a support for the razor blade that may be precisely adjusted to meet the operating requirements of the user.

My invention comprises a primary handle member having a sleeve threadably disposed about the central outer surface thereof. A safety shaving head adapted for holding a razor blade in position for shaving is disposed upon one end of the handle member, and a clamping head adapted for holdinga razor blade in position for conditioning is disposed upon the opposite end of the handle member.

With these and incidental objects in view, the invention consists in certain novel features of construction and combination of parts, the essential elements of which are set forth in the appended claims, and a preferred form of embodiment of which is hereinaftershown with reference to the drawings which accompany and form a part of this specification.

In the drawings:

Like reference characters refer to like parts throughout the following views.

My device is comprised primarily of a handle member 11, one end of which is bifurcated at 2, resulting in a top member 3 and a bottom member disposed in parallel. A clamping head 5 is disposed longitudinally of the primary handle member. A guard B terminates the head end of the bottom member l. A toothed comblike structure 1 terminates the working edge of the guard 6. An outer face 8 of thetop member 3 and outer face '9 of the guard 6 lie in a common plane. The clamp 5 is expanded at its outer end and terminates inclamping jaws it and it that are adapted to encompass the ends of a razor blade l l. 'Notches l2 and it are disposed in theopposite ends of the razor blade 14. These notches are preferably placed near the top edge of the blade and in registry alignment with each other. These notches serve as indexing means for precisely locating the razor blade in place.

Clamp 5 has a stem l5 extending inwardly along the axial center line of the primary handle member. The clamping head is extended to form a fan-like head as illustrated at I6 and an elongated slot I7 is disposed therein, through which adjusting screw l8 passes. The head end of the adjusting screw I8 is a free fit in hole Iii which is disposed within the top member 3. The adjusting screw 58 is threaded into the bottom member 4. The handle member is preferably made of spring material in order that the outer ends of the bifurcated handle member may be moved toward each other against spring tension. Rotation of the adjusting screw causes a relative displacement between the top and lower members of the bifurcated handle member, and consequently causes relative displacement between the cutting edge 22 of the razor blade and the outer ends of the guard teeth '5. Lugs 26 and 2! extend forwardly from the outer ends of the top member 3 and are made to engage with notches l2 and 13 disposed in the ends of the razor blade. The stem i5 is threadably secured to a finger adjusting nut 23 having a sleeve 2 t fixed thereto. A relatively long threaded connection is provided between the sleeve 24 and the stem Hi to provide for adequate travel of the clamping head 5 to freely release the razor blade when its removal from the safety shaving head is desired. I A stropping clamp 25 is slidably disposed relative to the primary handle member. A reverse bend 26 terminates the outer end of the stropping clamp. A lug 21 is disposed upon the elongated inner end of the stropping clamp. A friction sleeve 28 is disposed about the primary handle member l, and the stropping clamp extends therethrough. V-shaped notches 29 and 30 are disposed adjacent the back of the razor blade Hi. Wedge shaped jaws 3i and 32 are disposed respectively within stropping clamp 25 and on the c sleeve 28 and are held in registry alignment with each other, and are adapted for engaging within the V-shaped notches 29 and 30 of the razor blade, to hold the blade in fixed position for honing and/or stropping.

To place the razor blade Within the conditioning head of the razor frame, clamp 25 is moved outwardly to receive the blade between the clamping jaws, in which position the lug 21 engages with a shoulder 33, limiting the outward movement of the clamp 25. A band 34, thread-' ably secured to the primary handle member I, is made to abut the sleeve 28. When the razor blade has been placed within the clamping jaws 3i and 32 a tight clamping pressure is provided upon the blade by the longitudinal movement of a band 34 against the sleeve 28, said longitudinal movement being effected by the rotation of the threaded band 34 upon the primary handle member I. This places the razor blade under compression between the jaws of the conditioning head.

While the form of mechanism herein shown and described is admirably adapted to fulfill the objects primarily stated, it is to be understood that it is not intended to confine the invention to the embodiment herein shown and described, as it is susceptible of embodiment in various forms, all coming within the scope of the claims which follow.

What I claim is:

1. In a device of the class described, the combination of a safety razor blade having a substantially thick back, a pair of rectangularly sectioned notches disposed in the ends thereof, a pair of notches having a V-shaped section normal to the blade thickness disposed in the ends thereof between the said rectangularly sectioned notches and the said back, a safety razor frame member having two ends and adapted at one end for holding the safety razor blade in position for shaving and adapted at the other end for holding the safety razor blade in position for conditioning the same.

2. A razor blade, comprised of a one piece member, the said blade being thicker at its back than at any other point, a slot disposed within the oppositely disposed ends of the blade and in registry alignment with each other and that point of the blade ends disposed above the slots being V-shaped and the apex of the V being inwardly disposed from the outer edges of the blade ends.

3. In a device of the class described, the combination of handle member, a stropping clamp disposed longitudinally of .the handle member and outwardly extending therefrom, a reverse bend disposed Within the outer end of the stropping clamp, J-shaped jaws disposed in the outer end of the handle member and in the outer end of a friction sleeve, and disposed in registry alignment with each other, a lug disposed upon the inner end of the stropping clamp, said lug being adapted for engaging upon a shoulder of the handle member when extended to limit the outward movement of the stropping clamp, a friction sleeve disposed upon the outer end of the handle member, and a band threadably secured to the handle member and adapted for engaging the friction sleeve and for moving the same outwardly longitudinally of the handle member.

JOSEPH POLILLO.
