oomtms L. nmlmor ermal-man, n sssacnusnm SAFETY-RAZOR.

To all whom it may concem:

Be it known that I, CORNELIUS L. HARLEY, a citizen of the United States of America, residin at Springfield, in the county of Hamp en and State of Massachusetts, have invented a new and useful Safety-Razor, of which the following is a specification.

My invention relates to im rovements in safety razors, and consists o a holder for the blade and a detachable'handle for the holder j and by ;means of which the blade is wedged into lace and secured, both said holder and ban e being of certain pecullar construction, all as heremafter set forth.

The objects of my invention are, first, to produce a simple, strong, durable, com aratively inexpensive, and highly e clent safety razor, which consists of few parts, has adetachable handle, and which is so constructed that the .:blade can be easily, uickly, and conveniently introduced into t e holder and there secured, and as easily, quickly, and conveniently released and removed from said holder; second, to utilize in such a razor the handle as a ri 'd and safe bindin agent for the blade, an ,third, to provide or the razor a handle that is caevery case. These and other objects which will appear in the course of the following description I attain by the means illustrated in the accompanying drawings, in which-- Figure 1 is afront elevation of a Safety razor which embodies a practical form of my invention; Fig. 2, an end or side elevation of 'said razor; Fi 3, a similar view showing the holder an blade in transverse or vertlcal section; Fig. 4, a front elevation of the blade; Fig. 5, a rear elevation of the holder, the left-hand clamping lip being broken 011'; Fig. 6, a rear elevation of the device with all arts assembled and showin the holder with the blade a:ranged in a Fig. 7, a front elevation of the handle emmama... a Letters-Patent. PatentedDec.1912.

p lo ed in the first three views; Fi 8, a .7 rig t-hand side elevation of the han e em- 4 ployed in the sixth view; Fig.9, a left-hand side elevation of said last-mentioned handle, and, Fig- 10, a front elevation of said handle.

Similar fi res refer to similar 'parts throughout e several views.

Preferably the holder of this razor is made of sheet-metal stamped out, and thus made comprises a front plate 1 and a back plate 2 fastened together at the ends in such a way as to leave a narrow'space for the reception of a blade'3,which latter may be ofordina is provid at the ends with two lips 4 which are bent over the ends of and behind the plate 2. 'The plate 2 is provided with two ending? 5 at the top and with two In 6 of pec larformation at the bottom. I i- Sch lug 6 extends rearwardly from the base of the plate 2, and then forwardly to a point about on a line with thefaceof the plate 1 to form a blade support -7. .A serrated guard 8 of usual construction connects and is supported by the lugs 6, said guard being arranged with its teeth below a lane common to the two blade supports 7. e lips 4 are confined between the

lugs

5 and 6 and embrace the ends of the plate 2, thus fastening the two plates together in such a way that there can be no appreciable independent movement of said p ates relative to each other in an direction. When the lips-4 are bent aroun the ends of the plate 2, the bottoms of said lips may be sub ected to a little more force or pressure than the top thereof, for the purpose of rendering the space between the plates 1 and 2 for the blade 3 a trlfle narrower at the bottom than at the top. Removal of the blade from the holder is facilitated by attaching the front and back plates so as to leave the space between them wlder at the top than at the bottom, because then, upon inverting said holder, said blade slides out itself, and the blade can be more conveniently inserted. The lips 4 and the

lugs

5 and 6 afford very secure, practical and efiicient, and at the same time simple and inexpensive fastening means for the holder plates.

To insert the blade 3 in the holder, simply hold said blade with the bevel of its cutting ed the front and with'such edge down an slip it in between the plates 1 and 2, or

construction. The frontplate 1.

into the top of the space between said plates. Usually the blade 2 slips of its. own weight down between the plates 1 and 2 until it comes to rest with the extreme end portions of its cutting edge on the supports 7 although in some cases it will'be necessary to slide t e blade into this position with the fin er. The

downwardtoward the axis of the socket.

This socket is designed tore'ceive-a beak 10 at the upper end and forming "part of a handle 11 which will next be described.

The handle 11 may be ofany desired shape or'form provided it have the beak 10 at one end. The beak 10 is apart of the handle which is bent over so that its axis forms with 4 the main axis of the handle an acute angle while both axes are in the same plane. Ihe beak 10 is flattened on its upper or front side and tapered so as to form a chamfer 12 (or 12) and this chamfered beak is designed and adapted to enter the socket 9 behind the blade 3 with awedging fit and action, to the end that said blade is forced tightly-against the, late 1 and securely held in place and the hol er is attached to said beak with ample security owing to the frictional resistance existing between the engaging parts and members. 1

In practice, after the blade is placed in the holder the latter is mounted on or at tached to the handle ll-by inserting the beak 10 in the socket 9, only enough force to properly seat said beak in said socket be.- ing needed in order to produce a union of parts that is sufliciently strong and lasting for the purpose and so that there is no danger that said holder will drop ofi' of said beak during the shaving'operation. The razor is now ready 'for use like any other razor of this type. v

To dismount the holder or separate it from the handle, firmly gra one of these elements in each hand and?) the beak and start it from the socket, which can be done without difiiculty after a moments experiment. The parts are next entirely disconnected.

When the chamfer, as 12, is equally distributed on opposite sides of a plane common to the axis of. the handle 11 and its beak 10, as best shown in Fig. 7, the .holder and its blade are positioned when mounted rcibly loosen.

on the handle so that the cutting edge of said blade crosses such plane at right-angles, as illustrated in Figs. 1, 2 and 3; and when the chamfer, as 12, is unequally distributed on opposite sides of the aforesaid plane and takes adirection toward one side of the beak from the front end, as clearly shown in Figs. 8, 9 and 10, the holder and its blade are positioned when mounted on the handle so that the cutting edge of said blade crosses said plane slantwise or in such a way as to form angles other than right-angles therewith, as disclosed in Fig. 6. In the latter case a shearing cut is made with the blade when the handle is drawn strai ht away or in a direct course, while in the lirst case the blade in following the direct course of the handle makes a straight out in contradistinction to a shearing cut.

.As has been previously stated, the transverse angular direction of the holder and blade relative to the axis of the holder remains practicall the same regardless of the position of the c amfer on the beak.

Whenthe blade 3 is properly seated in the holder and wedged therem by the beak 10, the cutting edge of said blade is exposed below the bottom edges of the holder plates, and said bladelis prevented by said beak from being forced upwardly during the shaving operation.

The peculiar shape of the lugs 6 fits them for service in the double capacity of supports both for the lips 4 and through them the plate 1 and for the blade 3, as hereinbefore pointed out.

Without" departure from the nature of my invention, I may'm'ake certain changes in .the shape, size, construction, and arrangement of some or all of the parts of my razor as herein described.

What'I' claim as m invention,and desire to secure by Letters atent, is-

1. In a safety razor, a blade holder-comprising-a front plate provided with end lips and aback plate provided-with end lugs and rearwardlyand forwardly-extending bottom lugs havinglip-supportin parts andblade-supportmg parts, and her provided wlth a guard that extends between said bottom in s below said blade-supportlng parts, sai I lips being turned over hehind saidback plate and bearing with their upper and under edges respectively against said end and bottom lugs, and saidplates bemg arranged with a space between them for a blade;

2. The combination, in a safety razo'r, with a blade holder provided at the back with a socket which 0 ens into the ace in said holder for the bla e, of a handle aving a beak arranged at an acute angle to the handleand adapted to fit said socket and bear with itsfront side againsta blade in said holder, whereby said blade is held in said holder and the latter with its blade is supported adjacent and at an acute angle relative to said handle and said blade is directed downwardly and outwardly from said handle.

3. The combination, in a safety razor, with a blade holder provided at the back with an approximately semi-circular socket which opens into the space in said holder for the blade, of a handle having an approximately semi-circular beak in cross-section, which beak is chamfered on one side, arranged at an acute angle to the handle, whereby said holder with its blade is supported adjacent and at an acute angle relative to said handle and said blade is directed downwardly and outwardly from said handle, and adapted to fit said socket and bear with its chamfered part against a blade in said holder;

4. The combination, in a safety razor,
