RAZOR-BLADE HOLDER.

Application filed June 1, 1926. Serial No. 113,053.

The present invention relates to holding devices for safety razor blades and the like, and has for its prime object to provide a holder of the above character which is simple yet durable of construction and ellicient in use.

Another object of the invention is the provision ofa razor blade holder designed to permit rapid and secure attachment of the blade at the Correct angle for stropping thereof.

A still further object of the invention is the provision of a. holder of the above type which may be readily adapted for stropping various types of blades now on the market.

Still another object of the invention is the provision of a blade holder which will be convenient in. application and which can be manufactured at a comparatively low cost.

In the accon'ipanying drawings forming a part of this specification and in which like reference characters are employed to designate corresponding parts throughout the same:

Figure 1 is a side elevational view of my improved blade holder, showing a blade in operative position therein,

Figure 2 is a bottom plan view of the same, v Figure 3 is a partial transverse section showing the blade supporting plates in end elevation,

Figure 4 is an enlarged transverse sectional View taken on the line H of Fig ure 1,

Figure 5 is a side elevat-ional view of one of the blade holding plates of the preferred form of my invention.

Figure 6 is a similar view of a comple mentary plate,

Figure 7 is a partial transverse section showing a modified form of the blade holding plates in end elevation,

Figure 8 is a side elevational view of a plateemployed in this modified form of structure,

F'gure 9' is a side elevational view of a complementary plate,

Figure 10 is an enlarged transverse sectional view through a still further modified form of structure,

Figure 11 is a side elevational view of; one of the holding plates employed in this moditied form, and i Figure 12 is a side elevational view. of the complementary plate employed in the last mentioned form.

Referring to the drawing, wherein for the purpose of illustration is shown a preferred and several modified forms of my invention, the numeral 15 designates in its entirety the frameof my improved holder, the same being composed of a pair of longitudinal bars 16 preferably of metallic construction. These bars are secured in parallel spaced po sitions by means of a plurality of spacing blocks 17, formed of rectangular metallic blocks arranged at the ends of the bars and at the. intermediate portion thereof. The bars and blocks are provided with alined openings and secured by rivets 18 or in any desirable manner. lVith particular reference to Figures 1 and 2 of the drawing, it will benoted that the intermediate block 17 is arranged somewhat adjacent the forward end of the frame so as to provide ablade engaging portion at one end and a substantially longer handle portion at the opposite end.

Formed for resilient connection with the blade holding portion of the frame 15 are a pair of complementary blade supporting plates 19 and 20. These plates are prefer ably constructed of sheet metal and have their upper edges bent in substantially U- shaped formation a. at 21, the outer edges being inclined to provide a resilient gripping flange 22. These flanges 22 will overhang the upper edges of the frame bars to provide late-rally extending bevel supports by means of which the razor blade will be main tained in a proper angular position during the stropping operation. The lower longitudinal edges of the plates are beveled as at 23 to facilitate the movement of the holder on the strop. The plate 19 is provided with a pair of openings 24 arranged in horizontal alinement and adapted to engage a. pair of sleeves 25 carried by the complementary plate 20., as shown to advantage in Figure 4.

This type of blade holder is particularly adapted for stropping Gillette a'nd'similar razor blades, the intermediate portions of this type of blade being provided with a pair of spaced openings adapted to aline with the openings 24 formed in the holding plate 19. The blade is first arranged upon the sleeves 25 carried by the p1ate20 and the fit] complenientary plate 19 then inserted over the end portions of the sleeves. The razor blade and holding plates are then placed in proper stropping position in the holding, portion of the frame 1."), the upper flanged edges of the plates being snugly fitted over the upper edges of the frame bar. and held against displacement by the resilient structure of the holding flanges Thus the tisrtlltblttl device presents a structure of tapered. substantially V-shaped cross Section tor etlioicnt sharpening of the blade. The blade may he then conveniently and eliiciently sharpened by movement over the usual type of razor strop, in the same manner as the conventional straight. razor. This will greatly prolong; the usel'ulness ol' the blades and provide a sharper cutting edge so as to enhance the shaving quality thereot.

llith particular reference to l igurcs 7, and 9. wherein is shown a moditied l'orm of r-struciurc. the coniplementary holding plates lit; and Z" are similar in tormation to the plates 19 and 20 in the preferred form oi my invention.

iaped upper edge portions 255 iaving' re- These blades embody U- lient angular flanges Qt) for engagement v th the holder 't'rame. ne lOWQl edges oi the plates 26 and QT are beveled as at 30. while the plate 2? is. provided with a pair of openings 31. spaced farther apart than in the preterrtal form of holding plates, for aw in connection with the auto-strop and other blades ot similar formation. The c:unplementar plate Qt; is provided with siem'es 3:3 :rramred in tr; usverse alinement with the openings If ad: pted to be inserted therein. these sleeves being arranged for engagement with the semicircular notches termed. in the ends oi? this type oi blade.

These holding plates and the blade are. assembled in the 'lrame 15 in the same manner as previously described for the preferred form and tirmly hold the blade in position for stroppiug.

In order to acconmmdate safety azor blades of the (tem type. I provide a still further lnodilied form of holding means including a pair of dupli-atie plates 33 bent at the upper ends as at 3t and having resilirnt side flanges 235. The intermediate portions of these plates have longitudinal elots 36 of generally rectangular formation arranged in opposed iiiositions. These slots are formed to freely engage the rein forcing rib 37 of the Gem blade 38 so that when the holdin c plates are tightly inserted in the frame 15 the blade will be rigidly held in position.

From the foregoing description and the drawing. it will he r adily seen that I have provided a simple and durable type of blade holder designed to accommodate various forms of safety razor blades. The particular formation of the device will permit rapid connection and disconnection of the blades in the 'launc structure and greatly l'acilitate sbarpcnimr ol the blades.

is to be understood that the form of my ntion herewith shown and described be taken as the prelferred example of the zinc. and that various changes as to the size, slapc and :u'rangemeut of parts may be rtfiorted to vsithout departing from the spirit ol the invention or the scope of the subjoined claims.
