UNITED STATESTPATEI BLADE MAGAZINE Nicholas Testi, Boston, Mass assignor to Gillette Safety Razor Company, Boston, Mass., a cornotation of Delaware Application October 14, 1946, Serial No. 703,266

8 Claims. 1

This invention relates to magazines or receptacles for safety razor blades of the type designed to contain a convenient number of blades disposed in a stack and held securely and without contact of the cutting edges of the blades with the walls of the receptacle while the blades are contained therein or while being withdrawn, one by one, for use. I n I The device of my invention may be employed as a reservoir for a supply of sharp blades by the user, or it may be employed as a dispensing receptacle in which the blades are packed by the manufacturer and distributed to the trade, or for both uses. 7

Heretofore, many blade magazines have been designed to eject a blade much as an empty shell is ejected from a magazine rifle. The snappy discharge of the blade pleases many users and encourages them to draw liberally on the supply of fresh blades in the magazine. However, this system has the objectionable feature that a sharp blade may be thrown or may fall upon the floor where it is likely to be overlooked by the user or picked up by children.

It has been proposed to overcome these disadvantages by providing means for temporarily holding each blade, as delivered, in convenient position after it has been separated from the other blades in the stack and projected from the magazine. For example, the blade may be held projecting into space so that the user may conveniently and safely, and whenever convenient, take hold of it for the purpose of placing it in his safety razor.

.However, if the blade-ejecting feed slide is abruptly arrested at the end of its path while directly engaged by the fingers of the user, the fingers will slip forwardly from the feed slide and be cut by the edgeof the blade as it projects from the end of the magazine. This danger is obviated in accordance with the present invention by providing the feed slide with an elongated operating handle of such length that it may be grasped by the fingers of the user in a location in advance of the end of the blade. If there is any slipping of the users fingers from such a handle, it is in a direction away from the sharp edges of the blade instead of toward them. Where a handle of this kind is employed in a magazine which is constructed and arranged to deliver blades from both ends, the connection between the handleand the blade preferably includes means for causing the handle to assume a substantially horizontal position on one side or the other of the feed slide. This not only locates the handles conveniently for. use in the blade-ejecting operation but keeps th ma a ine a s m l n com a m the , illustration is adapted particularly for use in connection with safety razor blades of a well-known commercial type; that is to say, thin, flexible blades .004 to .007 inch-in thickness, longitudinally slotted, and having corner notches defining elongated unsharpened end portions in the blade as in the blades sold commercially under the trade mark Gillette. It will be understood, however, that the invention is not limited to that or to any specific kind of blade but with appropriate modifications may be easily adapted to blades of other kinds, all within the scope of the invention.

The magazine herein shown comprises walls forming an elongated rectangular enclosure. These include a bottom I0, side walls H and I2, and inturned top flanges I3 and M, which are spaced from each other and thus present a wide longitudinal opening. In the bottom of the enclosure is secured, by rivets or otherwise, a base plate l5 moulded of plastic material or formed of metal, as desired. From the base plate projects a central upstanding blade-locating rib I6 and a pair of flat blade-locating studs ll arranged in alignment with the rib l6. Corner posts l8 also project upwardly from the base plate l5, and these terminate a short distance below the top flanges l3 and I4 so as ,to permit the endwise movement of a single blade above them sliding in contact with the flanges.

At each end of the enclosure and beyond the blade-locating studs I! may be provided a fulcrum block l9 presenting an upper fulcrum surface 20 which slopes outwardly and upwardly from below the plane of the inner face of the top flanges 13 and M to a level above that plane.

. As herein shown, the fulcrum block is solid in 6 acaho d ns tnewerilly sq heti upgermos the magazine.

7 7 feed slide in such 'a-ma ner' as to fobvi blade in the stack is pressed into contact with the lower faces of the flanges l3 and I4. By

reason of its slot or fork, the spring 2I' clears v the rib I6 and the studs l1.

A feed slide 22 is arranged to slide longitudinally upon the magazine, having for this ur pose sidewalls which embrace the side walls of slide 22 may be provided with a pair of downwardly-extending ribs 23, so designed ears ranged, as to engage only the uppermost blade in the stack as the blade is accurately debated-at the level determined by the-interned flanges Q 3 and I4. Stop lugs 24 project from the flanges I3 and I4 and positively limit the mement oi definite predetermined length.

The bridge portion of the feed the blade-ejecting operation this relationship is maintained as suggested in Fig. 2. The result is that the users fingers, grasping the fingerpiec'e zflpa re always in advance of the end of the "lolade. If theffeed slide is abruptly arrested, the

When thesafety handle feature of my invention is embodied in a double-ended magazine, the handle is arranged to beswung 180 between consecutive blade-deliveringioperations. Accordinglythecross-piece zsxor the handleimay be slightly bowed and act as a spring, causing th'e handle to be thrown either into the horizontal position shown in Figs. 1 and 2 :or into an oppositely directed horizontal position when the feed slide is to be moved to deliver a blade from the righthand end of the magazine.
