Description

March 13, 1934. c, RUH-SERT BLADE HOLDER Filed June 2, 1933 NVENTOR. Christoph Ru hseri' ATTORNEY.

Patented Mar. 13, 1934 UNITED STATES PATENT OFFICE BLADE HOLDER Claims.

My invention relates to a new and useful improvement in a blade holder and has for its object the provision of a device whereby a safety razor blade or the like may be securely held in 5 position against the inner surface of a glass or other similar cylindrical or curved body, and moved while in contact therewith for honing or sharpening purposes.

It is another object of the invention to provide a device of this class which will be simple in structure, economical of manufacture, durable, light, and easily and quickly operated.

Another object of the invention is the provision of a device of this class whereby the supporting portion on which the blade is mounted may readily adjust itself to accommodate cylindrical bodies of various tapers.

Another object of the invention is the provision of a device in which a blade holding portion is projected inwardly of the cylindrical body with which used and a guide portion is adapted to embrace or contact with the outer surface of the cylindrical body.

Other objects will appear hereinafter.

The invention consists in the combination and arrangement of parts hereinafter described and claimed.

The invention will be best understood by a ref- 7 erence to the accompanying drawing which forms a part of this specification, and in which,

Fig. 1 is a perspective view of the invention.

Fig. 2 is a side elevational view of the invention showing it applied, with parts broken away and parts shown in section.

Fig. 3 is a sectional view taken on line 33 of Fig. 2.

The device comprises a handle-forming portion, and as shown in the drawing, this handle-forming portion is constructed by doubling upon itself a strip of spring steel to provide the normally separated

arms

8 and 9 which are bent into contact with each other at 10 and Welded together. An eyelet 13 is formed outwardly from the portion 10 to permit the device to be hung up when desired. The arm 8 carries a pair of

contacting guide strips

14 and 15, which project laterally from opposite sides of the member 8 at its free end. These

guide strips

14 and 15 are sharply angularly turned inwardly toward each other as at 16. The outer face of the free end of the arm 9 is pressed inwardly to provide the groove 1'7, and extending inwardly from the edge of the free end so as to project across the groove 17, is a slot 18. A blade holding plate 19 is provided with a lug 20 which projects through the slot 18.

A pin 21 is projected through the lug 20, and lies in the groove 1'7, so that the blade holder 19 is rockabiy mounted on the end of the arm 9. Spaced bosses 22 project outwardly from the front face of the blade holder 19. It is preferable that the plate 19 be magnetized so that a steel blade, placed thereon, will not fall off. The blade holder 19 is of less width than the blade 23 so that the cutting edges thereof project beyond the edges of the holder 19.

Most safety razor blades have a slot or an opening formed therethrough for mounting on a razor blade holder and in the use of this device, the blade 23 is positioned on the plate 19 with the bosses 22 projecting through the openings 24. The device is then mounted on a suitable cylindrical body which will serve the purpose of honing or sharpening. In the drawing, I have illustrated the device used with a tumbler 25. The

arm 9 is projected inwardly of the tumbler 25,

while the arm 8 is exterior thereof. The

members

8 and 9 are then pressed toward each other until the guide strips 14 and 15 engage the periphery of the tumbler 25 and the edges of the blade 23 are brought into engagement with the inner surface of the tumbler 25. While the device is gripped and retained in this position, the blade may be moved circumferentially of the tumbler for effecting the honing or sharpening desired. It will be noted that the tumbler is tapered, which is a general characteristic of tumblers. Were the device to be used with other cylindrical bodies, the same taper would be encountered and to compensate for this taper, the blade carrying plate 19 is rockably mounted. As previously described, this permits a self-adjustment of the device to the various tapers of the tumbler 25 or other similar bodies with which it may be used so that the longitudinal edges of the blade, which arethe cutting edges, will lie in contact with the cylindrical surface of the tumbler throughout their length and a universal sharpening or honing of the razor blade throughout its length may be effected.

It is quite customary for users of razor blades to hone the razor blade by use of a water glass, pressing the blade with the fingers against the inner surface of the glass and moving the blade circumferentially of the glass while so pressed against this surface. This often results in cutting of the fingers, and particularly it results in an improper or unsatisfactory blade, in that the pressure on the blade is not uniform throughout its length and a tilting of the same relatively to the axis of the water glass results. With the present device, the blade is uniformly pressed throughout its area against the concave or cylindrical surface, and a maximum efiiciency in sharpening is thus obtained.

While I have illustrated and described the preferred form of my invention, I do not wish to limit myself to the precise details of structure shown, but desire to avail myself of such variations and modifications as may come within the scope of the appended claims.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is:

1. A blade holder of the class described comprising: a pair of arms relatively movable toward each other at one of their ends; laterally projecting guide strips carried by one of said arms adjacent the movable end; and a blade supporting member rockably mounted on the inner side of the other of said arms adjacent its movable end.

2. A blade holder of the class described comprising: a pair of supporting arms relatively movable towards each other at one of their ends; guide strips carried on the movable end of one of said arms; a blade supporting plate; and means for mounting said blade supporting plate rockably on the movable end of the other of said arms.

3. A blade holder or" the class described comprising: a pair of supporting arms movable relatively toward each other at one of their ends; guide strips carried on the end of one of said arms; a blade supporting plate; means for rockably mounting said blade supporting plate on the movable end of the other of said arms, positioned inwardly thereof and directed toward the guide strip carrying arm.

4. A blade holder of the class described comprising: a pair of resilient arms secured together at one of their ends and normally spaced apart at their opposite ends; guide strips projecting laterally opposite from opposite sides of the free end of one of said arms; and a blade carrying plate swingably mounted on the free end of the other of said arms positioned inwardly thereof.

5. A blade holder of the class described comprising: a pair of resilient supporting arms normally spaced apart at one of their ends; guide strips carried on one of said arms and adapted for engaging the periphery of a cylindrical body with which used; a blade supporting plate; and means for mounting said blade supporting plate on the free end of the other of said arms in such a manner as to be movable relatively thereto for adjusting itself to the taper of the cylindrical body with which used.
