Jan. 28, 1930. w. G. LENZE 03 BLADE HOLDER Filed March 1929 INVENTOR BY/p ATTORNEY Patented Jan. 28, 1930 WALTER G. LENZE, OF WESTWOO'D, NEW JERSEY BLADE HOLDER Application filed March 1,

This invention relates to devices for holding safety razor blades, and more particularly to a holder for facilitating not only stropping but also honing of safety razor blades.

In general practice safety razor blades are merely stropped by users desiring to save in the use of safety razor blades. Invariably, however, mere stropping does not improve the keenness of the edge to a suflicient extent permitting the use of the blade more than a very limited number of times. It is well known that only honing on an oil stone will actually sharpen the blade to a degree which will make such blade as good as new.

For this reason I have devised a blade holder which will permit not only stropping of safety razor blades but also honing, thereby enabling the user to extract from a blade a long period of service.

The object of my invention, therefore, is to provide a simple, inexpensive and practical safety razor blade holder which will not only permit stropping but also honing of razor blades.

The foregoing and further objects will be more fully apparent from the following description and the accompanying drawings, forming part of my disclosure, but by no means intended to limit it to the actual showing, and in which Figure 1 is a plan view of a preferred form of my device.

Figure 2 is a side elevation thereof, partially in section.

Figure 3 illustrates side and front elevations of a blade guard.

Figure 4 is a cross sectional view, taken on lines 4-4 of Figure 1.

Figure 5 is a cross sectional view, taken on lines 5-5 of Figure 1, and

Figure 6 is a cross sectional detail view, taken on lines 6-6 of Figure 1, and showing the arrangement of the portion of the holder engaging a razor blade and provided with a blade guard.

Referring to the figures, it will be seen that my device comprises an elongated stamping made of resilient material. The shape of the 1929. Serial No. 343,705.

be handled.

In the upper face of the handle portion there will be seen a depression 11 so arranged as to provide a bearing 12 for pin 18 of a spreader bar 14, which extends partially beyond the handle portion and partialiy against the lower leg thereof. This spreader is shown in full lines in Figure 2 in its inoperative position and in dotted lines in its operative position, in which position it is adapted to spread or pry apart the reduced blade hclding portions 15 and 16, as inclicated in broken lines in Figure 2.

The movement of spreader 14 is limited by the position of the walls 17 and 18 of recess or depression 11.

Thus, when spreader 14: is in its broken line position, it cannot move any further and stands up a trifle beyond the perpendicular, thereby keeping the two blade holders 15 and 16 in spread rela- These blade holders nortion to each other.

mally abut with each other due to the spring tension exerted upon them by the resiliency of the material and by the shape of the handle portion from which they extend.

The lower blade holder is equipped with a pair of pins or extensions 19 provided with a transverse slot 20, the purpose of which will be explained presently. The upper blade holder 15 is provided with apertures 21, which are adapted to accommodate pins 19.

the honing operation.

In this manner the edge of the blade cannot be honed beyond a certain angle, which corresponds to the most advantageous angle of sharpening blades.

\Vhen it is desired to strop a blade of the Gillette type, a guard for one of its edges may be temporarily attached to the blade holders. Such guard is indicated in broken lines in Figure 1, and shown in detail in Figure 3 and in cross section in Figure 6. It consists of a rounded, hollow portion 22, terminating in substantially parallel extensions 23 and 24, adapted to normally bear towards each other. The upper extension 23 is provided with a pair of projections 25, adapted to register with the recesses 21 of pins 19 when the guard is slipped over one edge of the blade.

Referring to Figure 6, it will be seen that blade holder portions 15 and 16 are spread by the thickness of razor blade 26, whereby aperture 21 is elevated beyond recess or slots 20 of pin 19. It will be observed that projection 25 not only engages slot or recess 20 but also bears against the edge of aperture 21 of the upper blade holder. In this manner the guard is prevented from disengaging the blade holders, once having been forced over the beveled edges thereof and set in position as described above. The guard therefore will remain in its position until forcibly removed and changed to the other side of the blade holders.

The rounded portion of the guard serves not only for preventing damage to one of the razor blade edges, and the damage to the strop thereby, but also serves as guide and turning edge in the stropping operation.

While I have shown specific constructions of my device, be it understood that modifications and improvements may be incorporated therein without departing from the broad scope of my invention, for which I claim:

1. In a razor blade holder for facilitating both honing and stropping of safety razor blades, an elongated resilient member, bent upon itself to form a broad handle portion at one end, and a pair of upper and lower blade holding portions of reduced width atthe other end, said latter portions adapted to normally bear against each other, a spreading device for said blade holding portions associated with said handle portion and adapted to separate said blade holding portions when in operative'position, and to permit them to assume their normal, closed relation, when in inoperative position, a pair of ins or extensions associated with one of said lade holding portions, apertures provided in the other blade holding portion and arranged to accommodate said pins. transverse recesses provided in said pins, a blade edge guard removably associated with and engaging said blade holding portions, a pair of projections provided at one edge of said guard and adapted to register with the recesses of said pins and to engage the edge of the apertures of said other blade holding portion, thereby preventing the disengagement of said guard from the blade holding portions.

2. In a razor blade holder for facilitating both honing and stropping of safety razor blades, an elongated stamping of resilient material, bent upon itself, and forming a handle portion having rounded faces, and a pair of blade holders of reduced width and substantially diamond-shaped cross section extending from said handle portion and adapted to normally bear against each other due to the resiliency of the material and due to the shape of the handle portion, a spreader associated with and pivotally mounted in said handle portion and adapted to pry apart said blade holders, a pair of pins associated with one of said blade holders and provided with transverse recesses, corresponding apertures provided in the other blade holder and adapted to accommodate said pins, a blade guard of resilient material removably associated. with said blade holders and comprising an enlarged hollow portion adapted to guard a razor blade edge and terminating in substan ially parallel extensions, adapted to normally bear towards each other, a pair of inward projections provided at the edge of one of said extensions and. adapted to register with the recesses of said pins and further adapted to engage the edges of the apertures provided in said other blade holder, thereby preventing the disengagement of the guard from the blade holders.

In testimony whereof I affix my signature.

VALTER G. LENZE.
