Anthony Trumbich, of Chicago, Illinois. Safety-Razor-Blade Holder
1,366,140. Specification of Letters Patent. Patented Jan. 18, 1921.
Application filed July 23, 1919. Serial No. 312,758

To all whom it may concern:

Be it known that I, Anthony Trumbich, a subject of Jugo-Slavia, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Safety-Razor-Blade Holders, of which the following is a specification.

This invention relates to holders for safety razor blades designed for the purpose of providing a handle for the blade to enable the same to be honed or stropped.

The holder which is the subject matter of the present application for patent has been designed more particularly for attachment to a multi-edged blade, and the invention has for its object to provide a very simple and efficient holder, and one which can be readily applied and removed.

The object stated is attained by means of a combination and arrangement of parts to be hereinafter described and claimed, and in order that the same may be better understood, reference is had to the accompanying drawing forming a part of this specification.

In the drawing,

Figure 1 is an elevation of the device with the blade attached thereto;

Fig. 2 is a perspective view of a fragment of the device, without the blade;

Fig. 3 is a plan view of the blade; and

Fig. 4 is an edge view of the parts shown in Fig. 2.

Referring specifically to the drawing, 4 denotes a safety razor blade which is triangular so that it has three cutting edges. The blade has a central aperture 5 and three equidistant apertures 6 around the same.

The holder for the blade 4 has a straight shank 7 the inner end of which is reduced and threaded, as shown at 8, to receive a handle 9. At the outer end of the shank is a lateral bend 10 having at its extremity a side stud 11. At the junction of the shank 7 and the bend 10 is a side stud 12 on the same side as the stud 11. At the inner end of the threaded portion 8 of the shank is a shoulder 13 against which the handle 9 is screwed, the latter having a threaded opening to receive the part 8.

On the same side of the shank as the studs 11 and 12 is a latch which is angular in shape, one branch 14 being pivoted to the shank at its inner end, as shown at 15, and its other branch 16 having at its outer end a recess 17 to seat over the stud 11. The latch is offset from the shank a sufficient distance to clear the stud 12. Where the latch engages the stud 11, the latter has a side notch 18 to receive the latch end.

In use, the holder is applied to the blade 4 by placing the latter so that it lies flat against one side of the shank 7 and the bend 10, with the stud 11 seating in the central aperture 5 and the stud 12 seating in one of the apertures 6. The latch is swung to come alongside the blade and its branch 14 is forced over the stud 11. The blade is now firmly held between the latch and the shank 7 and its bend 10, and it is prevented by the studs 11 and 12 from turning or rotating.

The apertures 6 are located between the central aperture 5 and the corners of the blade 4, and straight lines drawn between said apertures would be perpendicular to the cutting edges of the blades. It will therefore be evident that the studs 11 and 12, in conjunction with the apertures 5 and 6, locate the blade 4 so that one of its edges extends parallel to the longitudinal axis of the holder, and as this edge is spaced laterally from the holder, the blade is supported in a natural position for stropping or honing.

After one edge is sharpened, the blade is released and turned to present the next edge, and so on until all the edges are sharpened.

In order to facilitate the manipulation of the latch, a laterally projecting finger piece 19 is provided at the junction of the parts 14 and 16.

I claim:

1. A holder comprising a shank having a handle at one end and a lateral bend at the other end, studs projecting sidewise from the bend at the inner and outer ends thereof respectively, a latch member pivoted to the shank and having a laterally extending portion adapted to come alongside the bend and engage the outer one of the studs; in combination with a razor blade of triangular shape adapted to be seated between the shank and its bend and the latch, said blade having apertures to seat the aforesaid studs.

2. A holder comprising a shank having a handle at one end and a lateral bend at the other end, studs projecting sidewise from the bend at the inner and outer ends thereof respectively, a latch member pivoted to the shank and having a laterally extending portion adapted to come alongside the bend and engage the outer one of the studs; in combination with a razor blade of triangular shape adapted to be seated between the shank and its bend and the latch, said blade having a central aperture to seat the aforesaid outer stud, and other apertures to seat the inner stud, the last-mentioned apertures being between the central aperture and the corners of the blade.

3. A holder comprising a shank having a handle at one end and a lateral bend at the other end, studs projecting sidewise from the bend at the inner and outer ends thereof respectively, a latch member pivoted to the shank and having a laterally extending portion adapted to come alongside the bend and engage the outer one of the studs; in combination with a razor blade having apertures in a line perpendicular to its cutting edge, said blade being adapted to seat between the shank and its bend and the latch, and its apertures seating the aforesaid studs.

In testimony whereof I affix my signature.

Anthony Trumbich.
