RAZOR-STROPPING DEVICE.

Application filed November To all whom it may concern:

Be it known that I, FRANK Mossnnao, a citizen of the United States, residing at Attleboro, in the county of Bristol and State of Massachusetts, have invented certain new and useful Improvements in Razor- Stropping Devices, of which the following is a specification.

My invention relates to that class of razor stropping devices intended for use in sharpening the blades of safety razors, and is priosed to maintain the blade perfectly rigir and at the angle best adapted to produce a keen cutting e ge; and to attain these results in a simple, inexpenslve, strong, and. easily operated structure.

To the above ends essentially my invention consists in the novel construction and combination of arts hereinafter described, and illustrated 1n the accompanying drawings, wherein-- Figure 1 is a side elevation of a razorstropping device embodying my invention, Figs. 2 and 3, top and bottom plan views respectively of the same, Fig. 4, a side elevation of the device with a portion of the handle broken away, showing a blade in engagement, Figs. 5 and 6, end elevations of the device in open and closed positions respectively, Figs. 7 and 8, sections on lines a; a; and y y respectively of Figs. 1 and 4, and Figs. 9 and 10, detail views respectively of the clamping member and blade.

Like reference characters indicate like parts throughout the views.

My device comprises a long flattened hollow ha'ndle portion A, of steel or other spring metal, provided with anextended longitudinally bifurcated portion, B. The upper outer end portion of the bifurcation, b, is preferabl slightly V-shaped. The bifurcation 0 the part, B, produces upon the handle two integral spring fingers, C and D, whose lower inner end portions are cut away or slightly recessed as at c and d res ectively. Integral with the fingers, C and respectively are downwardly directed longitudinally disposed ears or clamping plates E and F. The plate, E, is provided upon its inner face with two studs, G; and plate F is provided with openings, H, of slightly larger Specification of Letters Patent.

1 diameter. than the studs, and located in alinement with the latter to permit registration of the studs therein.

Near their inner ends the fingers, C and D, are respectively provided at opposite points in their side walls above the recesses c and d with oblong slots, I and J. The rear end portion of the slot, J, is enlarged to form a circular opening, K. A clamping pin, L, has near one end an annular groove, M, and

groove, M, forming the head, 0, and the grooves N forming the head I.

The clamping pin is slidably mounted in the slots I and J as follows: The margins of the wall 0 register in the straight grooves, N; and the margins of the wall D register in the groove M, as shown in Fig. 8, when the pin is in forward position and the fingers, C, D, compressed. \rVhen, however, the fingers, C, D, are released by sliding the pin to its rearward limit, the pin head, 0, is released from the walls upon entering the opening, K, which is of greater diameter than the pin.

In Fig. 10 is shown in side elevation a safety blade, R, which is typical of such structures, provided with a plurality of openings, T, in this instance three.

The blade, R, to be stropped is engaged in my device as follows: The pin, L, is in its rearmost position which permits the fingers, B and C, to separate. The blade, R, is then introduced endwise between the clamping plates, E and F, until the end openings, T, of the blade are in a position to receive the studs, G. The pin, L, is then slid forward compressing, through the fingers C and D, the clamping plates, E and F, against the faces of the blade, R. The studs, G, register in the openings, H.

The cut away portions, 0, and d, at the base of the fingers increase the resiliency of the walls at that point, thereby facilitating the clamping action. The flaring shape of the bifurcation, I), also contributes to the same result.

What I claim is In a razor stropping device, the combination with the handle, of two flexible fingers upon the handle, one finger being near its other end straight grooves, N; the

provided with an oblong slot, and the other around the slots, said grooves forming heads finger being provided with an oblong slot at opposite ends of the pin. terminating in an enlarged opening, and a In testimony whereof I have aflixed my slidable clamping pin of less diameter than I signature in presence of two witnesses.
