8 Claims.

My invention relates to improvements in stroking holders for razor blades of the form that is used to hold a blade for a safety razor for stroking on a razor strop or the like and the object of my improvement is to produce a stroking holder for razor blades of the form in which the blade is provided with an elongated transverse slot that extends across the middle of the blade for substantially the length of the cutting edges of the double edged blades and in which slot I nd it convenient and effective to house a key of rodlike form and that cooperates with a ribbed onepiece holder proper for holding the blade during the stroking or stropping, the ribs on the holder serving to provide the proper angle of contact with the strop for providing the proper edge to the blade.

In the accompanying drawing:-

Figure 1 is a side elevation of my improved stro-king holder for razor blades and with a razor blade held therein.

Fig. 2 is an edge view of the same.

Fig. 3 is a sectional View on an enlarged scale showing the invention in use, a part of a strop being shown.

Fig. 4 is a sectional view showing the partially closed end of the rib or trough in the bottom wing of the holder for retaining the key-rod.

Fig. 5 shows a blade.

Fig. 6 shows the blank for the holder proper.

My improved stroking holder for razor blades, as shown, is adapted for use with a blade IIJ of the two-edged form such as is in common use at the present time in that it is provided with a slot II of elongated form that extends transversely along the middle of the blade. Said slot I I is usually incidental to other details and merely serves to merge or inter-connect a set of openings of various forms that are adapted to cooperate with positioning projectors on one or the other or both of the elements of the blade clamping structure, consisting of the guard and the Icap. A screw-theaded handle may serve as the means for eiecting the clamping pressure.

In the present instance the slot I I is utilized substantially as a whole for operatively housing the device that serves as a key for holding the blade in place in the holder proper and the border edge elements I2 of nearest approach t against the key-rod I3 for effecting the positive positioning of the blade IIJ.

The key may be said to operatively ll the slot.

The slot II is nearly as long as the edges I4 of the blade I0.

The holder I5 comprises two similar blade parts I6 that are opposed to one another in faceto-face relation so as to be adapted to have the blade I slipped therebetween. Said parts I6 are in the form of plate-like blades of sheet metal p of appreciably less width than the length of the The wings I6 are parts of a one-piece structure I8 that is'made of material that is grooved from end to end and doubled back upon itself.

Such doubling back is preferably done to one side of the middle of the particular length of the stock that is utilized to make the holder proper so that the two wings will be of different length.

Thus, as shown, the return bend I 9 provides the hinge connection for the two wings, and the latter are as a whole longer than the transverse width of the blade so that by having the blade located. adjacent the free ends of the wings the holder portion intermediate the blade and the hinge connection will be adapted to serve as the handle for manipulating the device under conditions of use.

As shown, the lower or rear wing I6 is provided with an extension 2| of the free end portion that facilitates the insertion of the blade and the key into the operative relation.

When not in use the key is retained within the housing that is provided by the grooves I1 and to prevent accidental removal thereof the tip end portion 22 of the groove I1 of the extension 2I is partially closed so as to provide an abutment that serves as a retaining device.

The material that is shaped to provide the grooves I'I appear on the outside as ribs 23 that provide the desired angle of contact of the blade with the strop 24.

I claim as my invention:-

1. In a stroking holder forrazor blades, a holder proper comprising opposed plate-like wings, said wings being provided with registering grooves, and a key of rod-like form and uniform cross section tting within the space that is provided by said grooves, whereby means are provided for operatively holding a slotted blade positioned between said wings for stropping the blade.

2. In a stroking holder for razor blades as describedin claim 1, means inter-connecting said Wings at one end, one of said wings having an extension at the other end that overhangs the adjacent end of the mating wing, and the material of said extension being shaped to provide an abutment for the key at the extreme end of the groove therein.

3. In a stroking holder for razor blades as described in claim 1, said holder being in the form of a single piece of sheet metal, the two wings being connected by a return bend of the material.

4. In a stroking holder for razor blades, opposed wings of plate-like form having registering grooves on the opposed faces that cooperate to provide a housing chamber and having outwardly projecting ribs on their outside faces, and a rod-like key tting within and substantially tilling said chamber.

5. In a stroking holder for razor blades for use with a blade that is provided with a relatively elongated transverse slot along the body portion, a two-winged grooved holder proper for engaging the blade interposed between the wings and a key housed in the groove operatively holding the blade positioned when so interposed, and said key being in the form of a rod of plain form and uniform cross-section.

6. In a stroking holder for razor blades, a holder proper comprising opposed Wings held normal ly in opposed relatively elongated face-to-face relation by means of an integral return-bend and adapted to receive a razor blade between the two opposed faces, grooves in said Wings adapted to register with a slot in the blade for providing a housing chamber, the said return-bend being at one end, and a key in the form of a separate loose piece insertable in said chamber for retaining the wings and the blade in operative relation, one wing being longer than the other so as to provide an extension for facilitating the insertion of the key.

7. In a stroking holder for razor blades, a holder structure comprising a pair of opposed wings for receiving a blade therebetween, said wings being individually shaped so as to provide on the opposed inside faces registering chamber forming depressions and on the outside faces rib-like projections that extend longitudinally of the Wings, said Wings at one end of the structure being in the form of free end portions for permitting of relatively free and unobstructed admission of the blade, and the wings at the other end of the structure being operatively connected by means of an integral resilient return bend, the depression in one of said free end portions being obstructed by means of integral material near the tip end.

8. In a stroking holder for razor blades, a holder proper comprising opposed relatively elongated wings held normally in opposed face-to-face relation and adapted to receive a razor blade between the opposed faces, grooves in said wings adapted to register with a slot in the blade for providing a housing chamber, a key in the form of a separate loose piece insertable in said chamber for retaining the Wings and the blade in operative relation, and material integral with part of the end structure of said chamber shaped to provide an abutment for obstructing accidental escape of the key from the chamber.
