This invention cqmpr ses a and impr blade-dispensing magazine constructed. and arranged to contain a supply of sharp-edged blades. such as safety razor blades, to, guard their keen cutting edges against damage andv to permit the withdrawal of one blade at a time as required by the user.

An object of the invention is to provide a blade dispensing magazine which may be readily filled by the blade manufacturer by automatic ma-.- chinery and which will be so inexpensive in its construction that, the user may discard it after it has served its purpose. Preferably and as herein shown, the magazine is constructed and arranged to handle unwrapped blades. In this way the cost of individual wrappings is eliminated and. the. operation of filling or charging the magazine reduced to the simplest possible terms.

With these ends in view, an. important feature of the invention consists in. a magazine comprising a. single metallic strip folded. so. that it'provides upper and lower walls or a. base and cover for the magazine, the foldedv strip presenti at one end an exitslit for the blades, If desired, the fold vertex of the strip may be formed aseanenlarged loop for the convenience of the. user in handling the magaz ne, while the free ends of the upper and lower walls may be separated. to provide for the blades an. exit. slit which is equipped with a stripper.

Another feature of the invention consists in extending one or other wall of the magazine beyond. the exit. slit and shaping it so that it will serve as a stripper, yieldingly engaging each blade as it is'advanced through theexitsl-itand thereby preventing outwardmovement of. a second blade which might otherwise iamin the exit slit. This simple and eiTect-ive construction. permits the. blades to be arranged in stacked formation in. the magazine and eliminates the necessity for mechanical feeding means.

In one aspect, my invention comprises a blade magazine having a thumb or finger opening in its cover through which. the uppermost bladeflin the stack may be. engaged by the. user and advanced through the exit slit. This: mode of operation is facilitated by the stripping. function supplied by the extended wall of the. magazine, in this case the lower wall.

Another feature of the invention consists. ina blade-locating rib arranged to project upwardly from the lower wall of the masazine-thrughthe finger'opening' in the. cover and preferably to a level above the plane of its-center surface. Longitudinally-slotted blades may be located 49ml! rately within the magazine by such a: rib. Going more into detail, the rear end of the rib may be smoothly inclined. so that the solid endof. the blade may ride up upon it, thus flexing the blade transversely and subjecting it to a yielding. retarding action as the blade is ejected. Further, the forward end of the rib may be formed as an abrupt shoulder which will serve m prevent or obstruct the re-i-ntroductionxof a blade into the magazine through the exit slit.

These and other features: of the invention will be best understood and appreciated from the? following description of a preferredembodiment thereof selected for purposes of illustration and. shown in the accompanyingv drawings. n which:

The entire magazine is constructed from a single sheet or strip metal blank which may, be formed in a single dying-out operation and may be of the character shownin Fig. 3;, that is-tosay, it has an elongated rectangular body consisting. of a cover part It which mergesinto abottomor base part. I I. The cover part has side flanges l6 and an elongated finger opening. I8 therein. The base part is: molded with a central longitudinal rib l3 and with anend notch I4;

In forming the magazine the blank shown Fig. 3 is folded so that itpresents a. top w it. ()1: cover H1 and an underlying. bottom-wall or base I I disposed parallel relation throughout the major portion of their areasand connected. bi looped enlargement [2.. This .en-Iargementformsa convenient means-for the user in grasping the magazine by supplying a finger gripthicher than e b y of the m g zine- T e ribi3: is drawn from the metal of he bottom wall and. disposed longitudinally It vslopesupwardly at its rearend. and terminates at its forward. endrin; an abrupt shoulder as best seen: in. Figs- 5- and. notch IA extends inwardly" in the baseto the end shoulder of the: rib: l3 and in alignment therewith, in fact it is the removal of material in forming the notch that terminates the rib IS in its abrupt shoulder. The forked ends of the bottom Wall extend outwardly and upwardly beyond the inner edge of the top wall In which is flat throughout its entire area and serves at its free edge as the upper edge of a blade-exit slit. The forked ends of the base are curved upwardly to a level slightly above the plane of the inner face of the top wall it and thus drag resiliently upon the under face of a blade which is ejected from the magazine from beneath the top wall H3.

The side flanges it shownin Fig. 3 are turned downwardly to form the side walls It of the magazine and are crimped inwardly in areas I! to make interlocking engagement with the bottom wall ll of the magazine as clearly shown in Fig. 2. The top wall Ill is provided with an elongated finger opening l8 which tapers toward the blade-exit slot and in that opening is exposed the full length of the rib I3.

The magazine as herein illustrated is adapted for handling a double-edged safety razor blade of well-known commercial type, that is to say,

a blade having a longitudinal median slot 2| and elongated unsharpened end portions, although with appropriate modifications it may be easily adapted for handling blades of different contour.

As hereinafter shown, however, the blades 29 are arranged in stacked relation within the enclosure of the magazine wherein they are located by the rib l3 which fits with slight clearance within the blades. A stack of five blades 21) is shown in Figs.

5 and 6 and it will be seen that their inner ends lie within the loop l2. When the user desires to eject a blade from the magazine he has only to exert traction upon the uppermost blade by inserting his thumb or finger through the opening [8 and drawing it with the blade toward the exit opening. As the-uppermost blade of the stack is advanced in this manner its solid rear end will ride up upon the inclined rear end of the rib 13, thus flexing the rear end of the blade transversely against the sides of the top wall It] and exerting a yielding friction on the blade. As the blade is advanced, its solid end passes along the rib (2 in flexed condition as shown in Figure '1 while its advancing end is yieldingly engaged by the upturned end portions I5 of the bottom wall. These, as already pointed out, act as a stripper to arrest outward movement by an underlying blade in case it should happen to be dragged ahead by the blade being ejected. As soon as the rear end of the blade passes the forward end of the rib l3 it will snap down into a flattened position, leaving the blade projecting outwardly and upwardly at an angle as suggested in Fig; '7, and yieldingly engaged be-' tween the forward edge of the top wall 10 and the end projections I5 of the lower wall. In this position it may be very conveniently removed by the user and placed in shaving position in the razor. If desired the slot 2| of the blade may be engaged with the blade-locating rib of the usual razor and the blade removed from the magazine without further contact with the users fingers.

The magazine is preferably charged by the manufacturer with the supply of blades it is to contain'before the magazine is completely formed or at least before the side walls are crimped into interlocking engagement with the lower wall. It will be apparent that the abrupt shoulder of the rib l3 makes it impracticable to insert a blade into the magazine through the exit slot and thus an enlarged loop supplying a finger grip greater than the thickness of the magazine body, the upper wall having an elongated finger opening, and the material of the lower wall being folded to present an upstanding rib sloping gradually upwardly at one end from the plane of the lower wall to a level above the upper wall and terminating at its other end in an abrupt shoulder extending through the finger opening, the upper and lower'walls of the magazine being spaced from each other adjacent to said shoulder to afford a blade-exit slot.

2. A blade dispensing magazine comprising a sheet metal strip transversely folded to present upper and lower walls having a blade exit slot at their free ends, the upper Wall having an elongated finger opening therein and the lower wall having a'longitudinally folded blade-locating rib projecting upwardly through the finger opening and above the upper wall, said rib having a smoothly inclined rear end and an abrupt shoulder at its forward end in the vicinity of the exit slot, thereby permitting a longitudinally slotted blade to ride upwardly upon the rib in passing from the exit slot, and the lower wall having a notch in its free end that extends inwardly to the shoulder of the rib.

3. A blade dispensing magazine comprising a single strip of metal folded transversely to present the upper and lower walls of the magazine body providing a blade exit slot at their free ends, the upper wall having an elongated finger opening and the lower wall having a rib folded longiturinally and projecting upwardly through the finger opening and having an elongated notch in alignment with and terminating the rib, thereby providing an abrupt shoulder at the end of the rib remote from the fold vertex of the strip.

4. A blade dispensing magazine comprising a single sheet metal blank folded transversely to present upper and lower magazine walls having portions disposed generally in parallel relation and free ends spaced to provide an exit slot, the upper wall having an elongated finger opening, portions of the lower wall extending as a finger grip in loop formation below the plane of the parallel area of the lower Wall, and intermediate portions of the lower wall being creased longitudinally in rib formation and extending from the lower wall upwardly through the finger opening and above the parallel area of the upper wall and to a point adjacent said exit slot and terminating in an abrupt shoulder thereat.

5. A blade dispensing magazine comprising a sheet metal blank folded transversely and pre-- senting upper and lower magazine walls, the upper wall having an elongated finger opening therein, and the lower wall having an elongated notch in its free end and being folded longitudinally in a blade-locating rib that terminates in an abrupt shoulder at the inner end of the notch in the lower wall, and at its other end slopes gradually upwardly from the level of the lower Number wall to a point above the level of the upper wall. 1,178,967 JOSEPH MUROS. 1,370,560 1,451,279 REFERENCES CITED 5 1,834,284 The following references are of record in the 1,841,389 file of this patent: 1,909,919 UNITED STATES PATENTS 2330352 Number Name Date 521,116 Ingram June 5, 1894 Number 1,040,051 Swihart Oct. 1, 1912 456,176
