pletely removed. To this purpose, one end of the blade used in my device is transversely curved so as to form a scoop-shaped portion,

whereby the corn can be scooped out.77

For a complete understanding of my'invention, I refer to the annexed drawing, in which, by way of illustration, I have shown an embodiment of my invention and in which- Fig. 1 is a -longitudinal transverse section through the device showing the various parts assembled for use; Fig. 2 is a side view o the assembled device, a portion of the handle being shown broken away; Figs. 3 and 4 are views of the two ends of the head of the device together with the blade and the back-- ing therefor; Fig. 5 shows the backing for the blade with the attached fastening screw; Fig. G is another view of the backing showing the transverse curve atone end; Flg. 7 is a view of the backing showing the other end thereof;

` Fig. 8 is an underside View of the backing; Figs. 9,10 and 11 are respectively a side view, a -top view and an underside View of the head; Fig. 12 is a longitudinal section therethrough; Fig. 13 is a viewzof one end and Fig. 14 is a view of the other end of the head; Fig. 15 shows the blade.

As shown in Figs. 1 and 2, my device comprises three principal parts, to wit, a handle 1, a head 2 and a backing 3 for the blade. The backing 3 has attached it a screw-bolt 4 adapted to engage a corresponding female thread 5 in the tubular portion of handle 1. In the other end of the handleis fitted a conically-shaped piece 6 terminating in a ball 7 allowing the device to be secured in a clip in a boX.

The shape'of the head 2 is shown in the detail-views of Figs. 9, 10, 11, 12, 13 and 14.

As shown in those ii res, theI head 2 has a wide end, as at 8, an a narrow end as at 9.` Between these two ends the surface of the vhead is longitudinally curved as shown at 10 in Figs. 12 and 14. At the narrow end 9 5i the head is also transversely curved as shown at 11'in Figs. 10 and 13. At 12 in-Figs. 10 and 14 are shown chamfered portions, and at 13 and 14 are shown openings in the head for the purpose of allowing the shavings of the skin to pass out from beneaththe blade. Corresponding to the shape of head4 2, the backing 3 also has a wide end as at 15 in Fig. 8 and a narrow end, as at 16, and the underside of the backing is made concave to correspond to the convex surface of head 2. At 17 in Fig. 15 is shown the blade, which is provided with two cutting edges '18 and 19, and which has a central aperture 20 for the screwbolt 4 of the backing to pass through. A similar aperture 21, is provided in the head f 2, which aperture at its inner end is flared as shown at 22 in Figs. 1, 11 and 12 for the eni gagement'b the conical face 23 at lthe inner 7 end of han le 1. .5

The blade 17 is placed on top of the head 2 and the screw-bolt 4 on the backing 3 is then passed through the aperture 20 in the blade and the aperture 21 in the head, whereupon the handle 1 `is'screwed onto the bolt 4,` until the conical face 23 at the inner end of the handle engages the flared portion 22 of aperture 21 in head 2. The blade 17 thereby being firmly clamped between the concave inner face of backing 3 'and the convex surface of head2, is flexed and at its narrow end 19 `is transversely curved, as shown in Fig. 3 whereas the wide end 18 of the blade remains straight as shown in Fig. 4.

At 23 and 24 in Figs. 3 and 13 are shown rounded cheeks projecting above the bodyportion of head 2., so as to form together with backing 3 a smooth unbroken surface to thereby prevent any possible injury to the skin. 9 The screw-bolt 4, as shown, has a square thread, and the pitch is so selected that by a few turns of the handle the parts are tightor released to be taken apart.

ened together, f lo@ By means of the wide straight edge 18 o the blade large slices of callous or hardened skin can be removed, while by the narrow edge I9, which by the clamping together of the

parts

2 and 3 is transversely curved, the 5 deeper portions of a corn can be scooped out without any danger of cutting into the healthy tissues of the skin. Because of the apertures being provided in the head, the shavings and scooped-out portions will drop out without clogging the device and interfering with the operation of the device.A

It is obvious that the same arrangement for transversely curving'one of the edges of the blade could also be applied to safety razors of the Gillette type and, therefore, the appended claims are not to be construed to be limited to a device for removing corns or callous skin.

While I have shown and described an embodiment of my invention, it is, of course, understood that I do not limit mysel to that construction, because obviously my invention is capable of many modifications without a departure from my invention. I claim:

In a device of the class described, a guard frame comprising spaced side portions .and endY portions connecting the ends of said side portions, a blade supporting member integrated With the sides of said guard frame and spaced at its ends from the ends of said guard frame, a tongue at one end of said blade supporting member spaced from the sides of said guard frame and provided with a transversely convexed outer face dis osed y inwardly of the 'outer edges ofthe sid)es of the guard frame, and means for clamping a blade against the outer face of said blade supporting member.

40 In testimony whereof I my signature.
