STANLEY M. KATTELL, OF BIITGHAHETON, NEW YORK.

SAFETY-RAZOR.

Application filed March 5, 1913.

1 0 all to 7mm it may concern Be it known that I, STANLEY M. KAT'rnLL, a citizen of the United States, and a resident of Binghamton, in the county of Broome and State of New York, have invented a certain new and useful Improvement in Safety-Razors, of which the following is a full, clear, and exact description, reference being made to the accompanying drawings, forming part of this specification.

This invention relates especially to improvements in the blade-holders of safetyrazors, and it consists of a pair of combinedblade-holders, and includes the several features of construction which are hereinafter described and specified in the claims, the main object of the invention being to produce a very simple, as well as novel and highly satisfactory, razor to be sold for a small price.

On the accompanying sheet of drawings, on which like reference-munerals designate like parts of difi'erent views: Figure 1 is a side view of a razor embodying the invention and comprising two combined blade-holders; Fig. 2, another side View thereof, the bladeholders being shown in other relative posi tions; Fig. 3, an enlarged edge view of a portion thereof; Fig. 4:, an enlarged end View,

and Fig. 5, an enlarged sectional view, on the plane 00, m, Fig. 2, of a portion of a bladeholder ,containing a blade.

Each of the blade-holders of the razor shown, which embodies the invention in its preferred form, is made in one piece from a blank of sheet metal, although one much like it might contain two or more pieces and be made from stock of some other kind. A complete razor is composed of two bladeholders pivoted together, and two blades that fit in the holders, the blades being'substantially the same as some of the well known blades now on the market. Each blade-holder comprises a guard-plate a blade-hodling lip 2, and a tang which is a prolongation of the guard-plate and lip, and which includes parts 3 and l havlng extensions 5 and 6 respectively that form a finger-rest. The guard-plate and lip, which are united by a fold 7 of the metal, form sides of a recess which is open at its outer end and at the inner end of which is a stop 8, and the length of which is less than that of a blade, the stop being struck from the metal of the holder as appears by Fig. 5. In the lip is a slot 9, which extends through Specification of Letters atent.

the lip and is closed at both ends, one side of the slotbeing a narrow bar 10 that is curved slightly so that, as shown by Fig. 5, the middle of the bar is a little nearer than are its ends to the guard-plate 1. The length of that part of the guard-plate which lies close to the cutting edge of the blade, and in which are the notches 11, is greater than that of the recess above mentioned, the outer or 1 described, they nevertheless so differ in form that both lips 2 of the combined holders are on one side and both guard-plates are on the other side of the structure. Consequently the razor can be used with either hand with the same facility as can any razor which is not a safety-razor. The blade-holders of the razor are pivoted together as shown, one

of the parts 3 and 4: of one tang extending between the parts 3 and dot the other tang, and the pivot 15 passing through both tangs and being between the edge 13 of each guard-plate and the extensions 5 and 6, or fingerrest. formed on the tang. The construction and arrangement of the parts are such that the pivotal axis of each holder is in a plane that is parallel to the back of the holder and cuts the guard-plate from end to end, the lip being between the plane and back of the holder.

The same blades fit in both-holders of the razor, each blade being composed of a thin, oblong steel plate 16, having the cutting edge 17, and the back 18 consisting of a folded strip of metal covering the opposite edge of and afiixed to the plate or body 16. When the blade-holders both contain blades and the latter are in their proper positions in the holders, the backs 18 of the blades extend into and from the outer to the inner ends of the recesses above described, the inner ends of the backs being in contact with the stops 8, and their outer ends being uncovered so that the blades can be grasped with the fingers to be drawn out of the holders. The bars 10 on the lips 2 bear against the blades, on which they exert a yielding pressure like that of a spring, and which they hold snugly against the guard-plates, but they allow the blades readily to be withdrawn from and pushed into the holders.

In consequence of the formation and combination as described of the blade-holders of this razor, they can be arranged either as they are represented in Fig. 2, so that the razor can be put into a thin case but slightly longer than a blade-holder, or in many different relative positions to facilitate the use of the razor with either hand. It may be used in substantially the same manner as a razor'of the old style is commonly used, if the tang of one of the holders is grasped with the fingers and the tang of the other holder passes between the fingers as ordinarily the handle of the other razor does when it is in use. Therefore, each bladeholder is a handle when shaving is being done with the blade of the other holder, and then the guard-plate of the handle is a protector for the hand holding the razor, from the blade of the handle.

The form of the invention represented by the sheet metal blade-holders made and com bined as described is preferred to any other because of the facility with which such blade-holders can be manufactured, their pleasing appearance, and their durability, but it is to be understood that the invention may be embodied in blade-holders differing more or'less from these in details of construction.

Having thus described my invention, what I claim as new and desire to secure by Let ters Patent, is:

1. The combination of two blade-holders, each composed of a piece of sheet-metal folded lengthwise of the holder and forming a guard-plate, a blade-holding lip and a tang all of which extend lengthwise of the holder, and each of which includes a portion of the fold, the form and arrangement of the blade-holders enabling the ends of each to lie close to those of the other, with the folds parallel and the guard-platesoverlapped from end to end.

2. The combination of two blade-holders, each composed of a piece of sheet-metal folded lengthwise of the holder and forming a guard-plate, a blade-holding lip and a tang all of which extend lengthwise of the holder, and each of which includes a portion of the fold, the lip of each blade-holder having in it a narrow longitudinal slot and including a flexible bar that forms a side of the slot and edge of the lip and curves inwardly from the ends to the middle portion of the bar, and the form and arrangement of the blade-holders enabling the ends of each to lie close to those of the other, with the folds parallel and the guard-plates overlapped from end to end.

3. The combination of two blade-holders, each including means for holding a detachable blade and each having a tang including two parts, one of the parts of each tang extending between the parts of the other, and the tangs being pivoted together.

i. The combination of two blade-holders, each including means for holding a detach able blade and each having a tang including two parts, one of the parts of each tang extending between the parts of the other, and the tangs being pivoted together, and each of the parts of each tang having an eX- tension that forms part of a finger-rest.

5. The combination of two blade-holders,

-in which fit two detachable blades, each blade-holder being also a handle and comprising a guard-plate, a blade-holding lip and a tang, and the tangs being plvoted to gether, each guard-plate being a protector for the hand holding the razor, from the blade of the handle, when the other guard-' each guard-plate then to overlap the other LEWIS S.
