SAFETY-RAZOR. L

Specicat'iters Patent. i i 3tente'0613 17, 1916.

'Application led March 17, 191. Serial No. 84,957. i.

To all 'whom it may concern l Be it known that I, GEORGE W. LISHAWA, residing at Hartwell, Hamilton p county, State of Ohio, have invented certain new and useful Improvements in Safety-Razors, of which the following is a clear, full, and

4exact description, attention being called to the drawing which accompanies this application and forms a part thereof.

This invention concerns shaving implements of the safety `razor type.

In using a razor it is considered of advan- Y tage to bring the cutting blade as close as possible to the medium from which the action and directing movement proceeds.

This medium is the users hand and the fingers thereof.

The object of my invention is to provid certain new and improved means whereby the blade-holding devices may be held di rectly by the hand of the user, so that the action of the hand is transferred in the blade.

' blade to part 5.

The invention consists of these particular means and their construction as the same is hereinafter described and pointed out in the claims.

The invention is also illustrated in the accompanying drawing in which:

Figure 1, illustrates in a perspective view application of my improved razor to the hand and use thereof. Fig. 2, is an underside view of the razor as it appears in Fig. 1. Figs. 3, l and 5, show on enlarged scale each of the superposed parts of the razor as it appears in Fig. 2; Figs. 3 and 5, showing the parts between which the shaving blade A, shown in Fig. 4C is'held. Fig. 6, shows preliminary 4engagement of the assembled razor as shown in Figs. 1 and 2. Figs. 8, 9 and 10, are end views respectively, of Figs. 4, 5 and 6. Fig. 11, in a longitudinal section, still further enlarged, illustrates manner of assembling the parts of the razor and, Fig. 12, in a perspective view, with parts broken away, illustrates a modified construction.

In the drawing letter A, indicates the shaving blade having cutting edgesa-a on opposite sides."

B is the back plate having on opposite edges the guards b-. This plate is slightly curved transversely as shown in Figs. 7 and 12.

Fig. 7 is an end view of the y C is a cap-plate curved in a manner similar to plate B. Cap-plate C is provided with two hook-

shaped lugs

15 and 16, and the cutting blade has two, endwise open,

'

notches

17 and 18 in its opposite ends. 19 and 21, are openings in the backplate of hooks over the shaving blade as best shown in Fig. 6. Back plate B is now placed upon the assembled parts so that the openings in it are 'above

lugs

15 and 16, as shown in dotted lines in Fig. 11.' The parts `are now brought together so that the llugs pass through said openings after vwhich the plates are shifted, one' with reference to the other, so that the lugs hook over the back plate as shown in Fig. 11. dotted linesin Fig. 2. The parts so engaged are securely heldin this position by the action of the shaving plate which serves as a locking spring and vrmly draws the lugs of the capfplate which hook overthe backplate against this latter. This action is due to the resistance of blade A which in the assembled device occupies a constrained position by being forced to assume the curved shape of plates B and C, between which it is .clamped when these plates are engaged to each other. Observe Figs. l0 and 7 Security maybe added to the engagement by providing'the lugs with projections 22 adapted to slip into sockets 23 in backplate B while the parts are being assembled. y

In Fig. V12 a modified construction is shown of the means which serve for holding the cap-plate to the back-plate. There the lugs on the cap-plate are positioned dilerently and the back-plate is provided with pins 24 to be engaged by the lugs instead of having openings. the shaving blade may be dispensed with.

The shaving blade held as described is attached to the hand, respectively to one of the lingers thereof, by means of two clamping arms D-D, projecting outwardly from Observe also In this case notching of the opposite edgeslof the backplate and curved toward each other with their free ends in close approach. These arms may be attached to the backplate, by solder for instance, as indicated in Fig. 7, or they may l be integral as shown in Fig. 12. In this 4latter case the backplate with these arms may be in onestamping which is formed to shape. A portion of these arms between their edges is separated from 'the rest of the material and bent inwardly as best show-n at cZ-'d in Figs. 7 and 12, ,the object' being to cause these arms .to conform more closely to the shape of the fingerby enabling them vtri-encircle ythe same more completely.

The use of the implement isillustrated in Fig. l.l As shown there', it is mounted upon' the index 4finger but of course it maybe used upon any iinger including the thumb.

1 The two cutting edges are available, that is strokes may be applied in opposite directions, up and down for instance, withoutrequiring changes in position of the impleyment or of the hand beyond such which are due to the motion of the hand. r

Having described my invention, I claim as new:

1. In a shaving implement, the combination of a backplate and of a cap-plate, both curved transversely in the same direction, means for holding one to the other, a flat spring-plate having opposite cutting edges adapted to occupy a position between the plates and forced into a constrained position by them when said plates are connected to each other, thereby serving to maintain the engagement ofthe means whereby said plates are held to each other and curved spring-arms projectingoutwardly from opposite edges of the back-plate for clasping the implement upon one of the fingers of the user.

2. In a shaving implement, the combination of a cap-plate having lugs on one side thereof,

a double-edged shaving blade adapted lto be superposed thereon and provided with notches'inits ends adapted to clear these lugs7 a backeplate'provided with openings to receive these -lugs to be engaged by them after superposed upon the shaving blade and curved finger-clasping In testimony whereof, I hereunto aiiix` my signature.
