4 Claims. (Cl. 206-16) UNITED STATES PATENT OY FFlCE y The invention relates to improvements'in blade l1 and partial side walls IQ", and 20. This magazines for razors of the type such as is described in my United States application for Improvement in magazine for-razor blades, Ser. No. 104,984, filed October 10, 1936, allowed July 24, 1937. This type of blade magazine comprises a receptacle, or casing, which contains a blade holder or container so constructed and arranged that the topmost blade is in line with a discharge 10 slot in the casing and is capable of being discharged through the slot by means of a suitable ejector slide, such as will be presently described. The casing is provided with an aligning finger 9 which may be projected into a slot suitably ll positioned in the head of the razor into which a material how the magazine is aligned with the a razor, or whether it is separate therefrom or a part thereof. s

In blade magazines of this general type, .as modified by particular features of construction to which I will hereafter refer, it now and then happens that on retraction of the ejector slide (i. e., the member whereby a blade is ejected from the magazine and projected into the razor head), the act of retraction exerts sufiicient frictional contact on the topmost blade to cause it to be dragged back, with the result that the topmost blade jams in the mechanism or becomes partially ejected from the rear end and can be restored to position only with considerable trouble.

Referring to the drawing, 7 Fig. 1 is a view in elevation and in longitudinal section of an im'ector embodying my improvement;

Fig. 2 is a view in section on the-line 2-2 of Fig. 1;

Fig. 3 is a perspective view showing the plunger mechanism disassembled. I Refen'ing more particularly to the drawing, 'the magazine in which I embody the invention .comprises a box-like casing It provided with a longitudinal slot II in its upper wall and awider longitudinal slot l2 in its bottom wall. The 50 casing is open at its rear end .(the right side-of Fig. 1) but is closed at its other end by the wall l3, which is provided with an aperture ll for the reception of the projecting tip I! oflthe blade container, The blade container comprises a boxu like structure comprising the end'w'alls l6 and.

blade container contains a stack 2| of blades, the stack being upwardly and resillently'pressed by the spring 22, which may be attached as by a the rivet 23 to the bottom plate-24, which in turn covers the wide slot l2 in the bottom of the eas- I ing previously referred to. v

The ejector assembly consists of a slide 25 providedwith the lug 26 projecting up through the slot II in the top wall of the casing, thence through the slot 21 of the thumb piece 20, whereupon it is then turned over so that it securely locksthe thumb piece 28 and the slide 25 in assembled relation.

In operating the ejector assembly (assuming. for example, that it is in position shown in full lines in Fig. 1), the thumb piece is seized between the thumb andthe forefinger and-the assembly drawn to the rear of the casing until the tip 29 of the slide has passed thev rear end of the topmost blade 0 of the stack. Pressure exerted by the spring 22 then forces the entire stack-upwarly until the blade a. contacts with thetop wall of the casing and is in line with the slide. 7 Forward movement of the slide then drives the topmost blade a through the slot 30 in the front wall of the casing and into position in the razor head, (assuming that the finger has been projected into the usual slotin the razor head and the parts are in alignment). It is now quite ap- 30 parent that withdrawal of the ejector'assembly to the rear of the casing involves frictional con: tact of the slide with the topmost blade a which if, as it sometimes is, sumcient, will drag the topmost blade a back over the wall 3| of the blade 5 container, in which case it will not be possible to withdraw the slide sufliciently far. to permit the tip 29 thereof to pick up the blade a. It is, of course,,necessary to leave the gap 32 between the upper edge of the rear wall of the blade container, since otherwise it would not be possible to retract the slide sufllciently far to the rear to pick up a blade.

In order to avoid the possibility of the objectionable occurrence above noted, which is ordi- 4s narily'known as jamming," I provide the slide 25 with a spring tongue 33, the tip of the spring tongue being depressed as shown at 14. This spring tongue may be conveniently made by an ordinary stamping operation. It is to be noted that the normal position of the spring tongue'is such that the tip 36 resiliently bears downwardly against the topmost blade of the stack, but that its shape (as viewed in Fig. 1) .is such that it can ride over the rear wall 3| of the blade container when traveling in either of its two direc tions of travel. It is further to be noted that the bearing point of the tip 36 is to the rear of the bearing point 31 of the spring 22, so that the spring tongue 33 tends at all times to cause the rear end of the stack of blades to be forced downwardly against the resistance of the spring 22.

In explaining the mode of operation, it will be assumed that the ejector assembly is being retractedi. e., withdrawn from its position as shown in full lines to its position as shown in dotted lines (Fig. 1). wardly, the pressure of the tip 36 of the spring tongue on the topmost blade causes the stack, including the topmost blade a, to move slightly downwardly so that the topmost blade a is below the gap 32, and, therefore, any rearward motion of the topmost blade a would cause it to V abut against the end wall of the blade holder. However, thespring tongue tip 36 is capable of moving up and down in the slot II and therefore will ride easily over the rear wall of the blade container to the position shown in dotted lines. As soon as the tip 36 has cleared the topmost blade a, the rear end of the stack as a whole rises because of the pressure of the spring 22 until it contacts with the underside of the slide 25. Then when the tip 29 of the slide has by further retraction cleared the rear end of the blade a, the wholestack rises until the blade a is in contact with the upper wall of the container and is in line with the slide 25. Forward movement of the slide will then cause the tip 29 of the slide to abut against the rear end of'the topmost blade at and drive it through the slot and into the razor head with which the magazine finger 9 is engaged.

It is recognized that the present invention may be embodied in other constructions than those herein specifically illustrated, and there- 'fore it is desired that the constructions disclosed shall be considered as illustrative and not in a limiting sense.

I claim:
