STROPIPER FOR SAFETY RAZORS.

Application filed February 10, 1920. 'Serial No. 357,528.

1 advantages of which will be hereinafter set forth.

The main object of the'present invention is to provide a simple and effective holder adapted to clamp a blade of a novel type so that the blade may be readily and effectively stropped.

A further object resides in making the blade clamping member of such form that the blade may be readily placed in position therein without fear of injury to the blade or the cutting of ones hand in the act of placement.

With these and other objects and advantages in View, as will appear in the fol lowing description, reference will be had to the annexed drawings, wherein:

Fig. 1 is a perspective view of the blade holder in its open position with a blade positioned therein;

Fig. 2 a similar view of the combined handle and clamp and showing the closed clamp about to be inserted in the holder;

Fig. 3 a sectional elevation, on a somewhat larger scale, of the clamp and holder; Fig. 4: a perspective view of the holder in its omitted and Fig. 5 a transverse sectional view thereof.

The blade, denoted by l, is of the double edge type and has a notch, as 2, formedin each end thereof. The blade will also'preferably be formed with an opening 3 to one side of the medial line thereof which serves as an index so that the user may readily determine which edge is to be exposed for stropping purposes or which edge has been stropped.

The blade holder may be said to comprise two plates or leaf-like. members 4 and 5 pro- Vided with outwardly bowed or curved elements or extensions 6 at the rear thereof, one of said elements, as the upper one, bein provided with a series of curved tongues T which, cooperating with slots 8 formed in the other member, produce a hinge connecclosed position, the blade, however, being tion between the clamping plates. One of the plates, as the lower plate 4, is provided at each end with an upstanding lug 9 while the other plate has its ends notched out, as at 10, toreceive the lugs when the plates are closed into blade clamping position. Said plate 4 is likewise provided at each end with a second upstanding lug as 9 said lugs standing a slightly greater distance apart than the lugs 9 or a distance equal to the length of the blade. Plate 5 is also cut away at its forward edge, as at 11, to facilitate the placementof the blade upon the lowerplate; in other words, the recess forms a space for the accommodation of the thumb as the upper plate 5 is swung down into clamping position.

iVhen a blade is positioned, as in Fig. 1, with thelugs 9 engaging the walls of the notches 2, and the lugs 9 contacting the ends of the blade to prevent endwise movement thereof, the upper plate is swung downwardly into contact with the interposed blade. :The engagement of the lugs with the blade and the notches therein prevent shifting of the blade relative to the clamp and the parts are, so proportioned that the innermost edge of the blade is held out of contact with any part of the clamp which might injure its then innermost edge.

The holder for the clamp may be said to compris a handle 12 from which extends-a tubular longitudinally slotted body or member 13, the back 14. whereof. opposite the slot i'srounded and smooth. Said body is of such cross section that its edges will exert such a degree of pressure upon the blade clamp as to cause the elements 4 and 5 thereof to firmly clamp the blade when the clamp is inserted endwise into the holder as indicated in Fig. 2. .The handle will preferably be connected to. the body of the holder by a reduced neck portion 15, the neck merging into the body proper upon curved lines so as not to out or score the strop when in use. Furthermore, to ensure the proper spring action between the edges of the body,"

which body is made of relatively stiff material, I prefer to out the body away at each side, as at 16, adjacent the neck.

From the foregoing it will be seen that the structure is relatively simple and yet withal durable and effective and easy of manipulation.

What is claimed is,--

1. In a stropper for'safety razor blades,

the combination of a holder and a blade clamp, said clamp comprising two plate-like members hinged together at one side and oneof said plates having a notch formed in each end and the other of said plates hav-' ing two lugs extending upwardly from each end, one of said lugs passing into notches formed in the end of the blade to be clamped and the other contacting the end of the blade whereby shifting of the blade with reference to the clamp will be prevented.

2. In a strop-per for safety razor blades, the combination of a blade clamp consisting of two plate-like members, said lates being reversely curved'adjacent one edge thereof, fingers extending outwardly from the edge of the curved portion ofone of said plates naeepae and entering slots formed in the opposite plate, thereby forming a hinge connection between the plates; a pair of lugs extending upwardly from the ends of one of said 1 plates and adapted to pass into notches to bear against the ends of the blade; anda longitudinally slotted holder into which the clamp is adapted to be slidendwise to maintain the plates in clamping relation to aninterposed blade.

In testimony whereof I have signed. my name to this specification.
