RAZOR BLADE HOLDER Filed A ril 22, 1957 lmrenfor CLAREncE W. 001.1.1/512 Patented Jan. 10, 1939 UNITED STATES PATENT OFFICE 2 Claims.

The present invention relates to holders for safety razor blades either single or double edge for the purpose of stropping such blades.

An object of the present invention is to provide a simple holder to which the blades may be readily and conveniently secured for stropping and wherein they are securely held in the holder during this operation.

One of the objects of the present invention is to simplify and expedite the process of stropping the blade, wherein the desired results may be obtained without the necessity of rolling the holder turn for each stroke.

In the present invention the operator simply presses the thumb on the holder and over the blade at the same time gripping the handle, drawing the blade across the

strop

4, 5 or 6 times while in this position. The holder is then reversed and held in the same manner and the stropping done with reverse strokes, the thumb being used to secure the desired strop pressure against the blade.

One of the objects of the present invention is to inaugurate an entirely new method of stropping safety razor blades. A method which is not only safer but is more efiicientthan the old method and one which, with ordinary eifort, will provide a keener edge and smoother shave, and extend the life of the blade for almost an indefinite period.

To these and other useful ends my invention consists of parts and combinations thereof or their equivalents as described, claimed and shown in the accompanying drawing in which:

Fig. 1 is a side view of one form of my invention showing a well known double edge blade in the stropping position.

Fig. 2 is a front or edge view of the device as illustrated in Figure 1, but minus the blade.

Fig. 3 is an enlarged front end view of the device as shown in Figures 1 and 2.

Fig. 4 is a section of the handle and blade locking plate taken on line 4-4 of Figure 1.

Fig. 5 is a fractional view partially sectioned, of a holder and handle similar to that shown in the other figures and having a modified form of looking device.

As thus illustrated I provide a handle member designated by numeral I, which is preferably made from fiat stock and folded, forming a seam as at 2 the shape of the handle in cross section being preferably as shown in Figure 4. I provide a slot 3 in the handle, the purpose of which will hereinafter appear.

The forward end of the handle designated by numeral 4, is preferably made U shaped as clearly illustrated in Figure 3, and being adapted toembrace the blade holding member 5 as illustrated in Figures 1 and 3. This blade holding member is also U shaped, the lips converging and being tapered as at 66, leaving an open gap 1 suitable for the reception of the razor blade.

Member 5 has thereon a out free portion I2 which is bent inwardly at right angles as illustrated in Figure 3, extending into or through an opening I3 in the opposite side of member 5. Cutaway portion It provides means for observing the proper-position of the blade whereby member I2 may be caused to enter the adjacent depression I I in the blade. Thus the outer end of the blade will be securely held into position. I provide a cutaway portion I4 in member 5 and on the same side of the holder as member I3, whereby the depression I I at the other end of the blade may be observed.

I provide a holding plate I5 having a bolt I6 which passes through slot 3, as clearly indicated in Figures 1 and 2. A nut I! is screw threaded on bolt I5 whereby member I5 may be locked in its forward or rearward position. To secure the rear end of blade I I! to the holder, all that is necessary is to push member I5 forward by pressure on nut I! so'tne front end of plate I 5 will fit into depression I I, thus the inner end of the blade will be securely held into position after nut I! is made tight.

Thus it will be seen by scrutinizing Figure 1, that the blade is securely held into position and cannot be dislodged after which the operator may with safety strop the blade on each side as herebefore recited.

One of the advantages of applicants device is that it is narrow so the angle of contact between the blade and strop may be adjusted by the operator by simply pulling more or less on the strop. If, however, the handle and holder were made wide as is the custom in devices of the kind, the strop will contact the blade edge at too great an angle and the life of the blade will be considerably shortened by quickly forming a blunt cutting edge.

When stropping a new blade, the operator may hold the strop taut so as to preserve for a time the original long edge and then reduce the tension on the strop as the blade becomes worn. Thus it will be seen that a narrow handle or holder is particularly adapted for the method of stropping as herebefore recited because in one way stropping, the natural tendency is to keep the strop taut.

Referring now to Figure 5. Handle 20 is pro- 2 vided with a slot 2| which is somewhat wider than slot 3. The holding blade means on this handle is similar to that shown in Figures 1, 2 and 3. I provide a locking plate 22 having a U shaped projection 23 which extends through slot 2i as illustrated.

I provide a V shaped spring having arms 24-44 and a U shaped projection 25 on its center which is adapted to be embraced by member 23. The free ends of members 24 are suitably rounded as at 26-26 and the spring is shaped whereby when it is inserted into the handle, the arms will exert considerable pressure against member 22 whereby this member will remain in whatever position it is moved to. Thus clearly the blade may be locked by moving member 23 forward and unlocked by moving this member in the opposite direction.

One of the advantages of the device illustrated in Figure 5 is that it is simple and projection 23 is considerably smaller than nut ll so that it cannot by any means contact the strop or inconvenience the operator.

It will be understood that I do not wish to be limited to the particular style of blade shown in Figure 1. My device may be adapted to hold a single edge blade in which case member 5 will be considerably narrower and the back edge of the blade made to rest against stops in the holder, the holding member l2 and plate IE or 22 resting on the projection at the dull edge of the blade. When my device is to be made suitable for single edge blades, I may elect to form the handle and blade holding means from a single fiat piece of metal. Such blades are quite narrow and stock which is wide enough for the handle will, when formed, be Wide enough for the blade holding means also.

It will further be understood that minor changes may be made in the various parts of the handle and holder without departing from the spirit and scope of this invention as recited in the appended claims.

Having thus shown and described my invention I claim:

1. A safety razor blade holder comprising in combination, an elongated handle member formed from a U-shaped piece of sheet metal, said piece being closed for a distance from one end to thereby form a hollow handle, the remainder being left open, a U-shaped blade holder, the closed side being embraced by and secured to said open end, said blade holder being adapted to embrace the blade to be stropped leaving a relatively small portion of one cutting edge exposed, a stop on the outer end of said blade holder adapted to engage a notch on the adjacent end of the blade, a slot positioned in the closed edge of said handle and being in longitudinal alignment with and adjacent said blade holder, a slidably mounted member positioned under said slot and adapted to optionally engage a notch on the adjacent end of the blade to be stropped and having a member which protrudes through said slot whereby the slidable member may be manually moved into and out of engagement with said second notch, a V-shaped spring positioned within said handle, the apex of said spring being in operative engagement with and adapted to hold said slidable member in predetermined positions.

2. A safety razor blade holder comprising in combination, an elongated handle member formed from a U-shaped piece of sheet metal, said piece being closed for a distance from one end to thereby form a hollow handle, the rema1n der being left open, a U-shaped blade holder, the closed side being embraced by and secured to said open end, said blade holder being adapted to embrace the blade to be stropped leaving a relatively small portion of one cutting edge exposed, a stop on the outer end of said holder adapted to engage a notch on the adjacent end of the blade, a slot positioned in the closed edge of said handle and being in longitudinal alignment with and adjacent said blade holder, a slidably mounted member positioned under said slot and adapted to optionally engage a notch on the adjacent end of the blade to be stropped and having a member which protrudes through said slot, whereby the slidable member may be manually moved into and out of engagement with said second notch, means adapted to hold said slidable member in predetermined positions.
