This invention relates to improvements in magazines safety razor blades.

This application is a division of Patent No. 2,327,388, issued August 24, 1943.

Briefly, it is an object of my invention to provide for a magazine for razor blades which is inexpensive to manufacture, simple in construction and easy to manipulate.

More particularly, an object of my invention is to provide an improved magazine for doubleedged razor blades which provides for automatically positioning the blades and for fitting the blades into a razor and for retaining the blades in a central position within the magazine so that the cutting edges are out of contact with the magazine walls.

A further object of my invention is to provide a magazine for double-edged safety razor blades which will assure the feeding of a single blade from the magazine into a razor.

For a fuller understanding of the nature and objects of my invention, reference is had to the following detailed description in connection with the accompanying drawings, in which:

Fig. l is a side view of a magazine showing a razor head in position upon same and showing the upper blade being fed into the razor and ejecting the used blade from the razor.

Fig. 2 is a top view of the magazine shown in is a section taken through line 3-3 of s lg. 2.

g. 4 is a front view of the magazine shown in i igs. 1, 2, and 3, with the front wall removed.

Fig. 5 is a perspective View of a modified doublesafety razor blade magazine.

6 is a longitudinal section of the magazine s--wn in Fig. 5.

'2' is a top view of the blade pusher in relaion to a blade with the blade partly broken away.

i 8 is a plan view of the blank of the magazine shown in Figs. and 6.

Fig. 9 is a perspective view showing the magazine shown in Fig. 5 in position with a spreadable razor.

Referring to the drawings, Figs. 1-4, inclusive, numeral 99 is a magazine for double-edged razor blades comprising a bottom I00, sides Hit-4M, vertical members IfiZ-HJZ, flanges l[l3--Ill3 bent horizontally from the channel members IllZ-IHZ, ribs IDA-I04 pressed into the flanges IIl3-I03, all of the above being fashioned from one piece of material. The front part of vertical members 532-482 is curved inwardly as shown at I05, and the front part of each flange HIS-403 is curved upwardly, as shown at I06. Between the sides iOI-ifll and IBZ-IUZ, there are longitudinal channels I91. Between the sides IflI--IOI and bottom IIlIl there is a stationary sloping back I08. At the front of magazine 99 there is a vertical movable front wall H39 riding in grooves in sides Ill! and sloping in the same direction as the back i538 and parallel thereto. A spring IIl'I bent upward from the same material as bottom I00 retains front wall i953 under upward pressure. The top of wall Hi9 has a flange III bent forward and small projection H2 bent rearwardly at the center. Bottom ltd has a spring H3 for retaining a stack of blades I Hi under upward pressure. In order to use magazine 99 in connection with a razor, the razor head is placed with the head downward upon flange HI and pressed down. This causes the front wall It!) to descend at the same time causing small projection I I2 to depress the stack of blades I M with the exception of the uppermost blade lib. As the razor head is thus pressed downward upon flange I I I, it is also -aoved horizontally into the magazine 99. The guards of the razor enter channels I0'I-I0'I because of the inwardly curved members shown at which causes the split razor head 50 to spread gradually since the distance between channels ililllll is greater than the distance between the guards of the razor. The platform of the razor enters the space between the long ribs set-act. The downward movement of the front wall M9 creates a clearance for the entrance of the cap of the razor, leaving the uppermost blade H5 ready to contact the used blade H6 in the razor head. As the razor head is moved into the magazine 99, the uppermost blade H5 contacts the used blade lit in the razor head and ejects it. while the uppermost blade I I5 enters the razor head.

Upon withdrawing the razor from the magazine 99, the razor head contracts and automatically positions the blade firmly in the razor head ready for use. The blade below blade I I5 which is now within the razor becomes the top blade and is retained by projection H2 and rests against ribs l under upward pressure.

Spring l I3 is attached to the bottom IOU of the magazine so that it constantly maintains upward pressure upon the stack of blades II4, so that the uppermost blade is always in position to be fed into the razor in the manner aforesaid. It should be noticed that the stack of blades H4 is stepped by the angular position of the front and rear walls I09 and H38, respectively.

The stack of blades I It is retained in the magazine by the upward pressure of the spring so that the cutting edges of the blades do not at any time contact the side walls IllI-III of the magazine since the magazine is much wider than the blades. When the razor head enters the magazine, the razor head is spread apart so that the cutting edges of the blade are not marred upon entrance into the razor head. When the razor head is removed from the magazine, the razor head contracts gripping and positioning the blade in shaving position.

Referring to Figs. 5 to 8, inclusive, numeral IIB represents a modified magazine for doubleedged razor blades, comprising a bottom II'I, sides II8-II8, a back H9, a front I2il, a top I2I and a vertical tongue I22 located in the center of front I20. Front I20 has a horizontal opening I23 near the top I2I. Top I2I has a longitudinal opening I24 along the longitudinal medial line. Finger piece I25 attached to pusher I26 through the opening I24 slides along the top I2 I. A spring I36 is attached to the bottom II! on the inside of the magazine to hold a stack of blades I35 under upward pressure. The uppermost blade I21 of the stack of blades I35 fits within the recess I28 of pusher I26, while extensions I29I29 embrace the uppermost blade I21 to assure movement of blade I21 along the medial line of the magazine, preventing the cutting edges from touching the inside walls of sides II 8I I8.

When the vertical tongue E22 of the magazine shown in Fig. 5 is projected between the flanges of the spreadable razor, shown in Fig. 9, the complementary parts of the blade platform of the razor are forced away from each other to an extent whereby the'distance between the pair of abutments On one plate and the pair of abutments on the other plate is greater than the width of the blade to be used in the razor, so that a blade can be ejected into the blade confining space without hindrance from the abutments. When the vertical tongue I22 is withdrawn, the complementary parts come together causing the blade to be gripped between the opposin pair of abutments and, therefore, rigidly held in position for shaving.

Referring to Fig. 8, numeral I36 is a blank for the upper part of the magazine shown in Figs, 5 and 6 comprising the back H9, sides iiii-i l8, front mil-Q28, tongue I22, top I21 and cutouts i'S'I to form opening I24 shown in Fig. 5. Top portions I2I are cut horizontally at and vertically at I33 adjacent the back lit and extend to the center of back II9 forming an extension beyond' the back. Top IZI is bent at Hi l which is slightly above sides Ii8il8 to form front opening I 23 and rear opening I35.

It is obvious that various changes and modiflcations may be made in the details of construction without departing from the general spirit of the invention, as set forth in the appended claims.
