blades Within the upper compartment of the magazine. Moss or other elastic substance 22 may be utilized to hold a stack of used blades up against the spring catches in the position shown in Figure 1. In removing a blade, the upper end of the magazine is pressed against the end of an open razor as indicated in Figure 5. The catches 28, being slanted as at 23, will spring apart so as to pass over the ends of the blade but, as soon as they have done so, will snap together as indicated in Figure 5 for holding the blade. The magazine may be pressed down on top of the razor, while held vertically or may be held horizontally or in any other convenient position which does not cause the blade to drop out prematurely.

The normal operation of the device involves: first, the opening -of the razor so as to expose the blade therein, in whatever way is provided for the razor in question; secondly, the used blade end of the device is pressed down onto the used blade in the razor until the blade is caught by the catches 28, at which time the magazine is withdrawn, thus removing the used blade; thirdly, the magazine is reversed so as to bring the bottom blade of the stack of new blades in position over the blade retaining member or members of the razor and the ejector I6 is pressed to drop the blade into the razor; the razor is now closed in whatever way may be provided and the operation is completed.

Sufficient space will be provided in the used blade compartment to hold as many blades as are sold in the stack of new blades within the magazine. When all new blades have been used, the magazine may be discarded or returned and exchanged for a fresh magazine.

The central supporting rib 8 may be modified in various ways, to provide for freeing a blade by transverse movement thereof. In particular, the structure may be modified as indicated in Figure 6, in which corresponding parts are indicated by the same numerals as used in connection with Figures l to 5. The central rib 8a is generally the same as the rib 8 previously described and is formed with'a lower shoulder Illa-which is the same as the shoulder I0. Instead of cutting away the lower corner thereof as at I5, this corner is rounded off as indicated at I5a. As will be apparent, when the ejector I6 is operated, the lowermost blade will be pushed downwardly slightly as it comes against the rounded corner I5a and will then be snapped out of position. The radius of the rounded corner I 5a is selected so as to prevent injection by friction or otherwise of the immediately overlying blade.

In Figures 7 and 8 a further modication is illustrated, in which the ledge I I is eliminated and the blade is supported on ledges formed on a bar 8b which replaces the bar 8 of previous figures. This bar 8b is formed with lateral enlargements or ribs 30 and 3I adapted to t within diamond shaped or similar cut outs in a blade. At their lower ends, the gibs 30 and 3I are formed with

ledges

32 and 33 for supporting the blade as indicated in Figures 7 and 8. A lower corner of the bar 8b is rounded off as at |51), much as in the embodiment of Figure 6, to permit transverse movement of the blade for ejection. As will be apparent, movement of ejector I6 pushes the lowermost blade transversely (to the left of Figure 8) so that the blade passes off the

ledges

32 and 33 and is dropped into a razor. In Figure 7, for clearness, the blade outline is indicated in phantom, and a blade with a diierently shaped central aperture from that shown in Figure 1 is selected for the purpose of illustration.

, most blade.

The ejector means may also be associated with the blade carrying rib and mechanism of this type is illustrated in Figures 9 and 10. In these figures, the rib 8c is generally similar to the rib 8b of Figure 8, and has similar blade guides or ribs 4|] and 4I, provided with

blade supporting ledges

42 and 43. The rib 8c. however, is provided with a cut out 45 for accommodating an ejection spring 46 which is fastened to the cut out wall as at 4l and has a toe or blade ejecting member 48 at its bottom. The spring is preferably designed so that toe 48 presses downwardly against the lower edge 49 of the cut out 45 for maintaining it in a fixed vertical relationship to the

blade supporting ledges

42 and 43. Toe 48 is positioned for engagement with a boundary of the blade cut out in the lowermost blade, upon leftward movement and may thus be employed for ejecting a blade in a manner otherwise similar to the operation of the ejector I6 of previous figures. The ejector spring 46 may be operated in a variety of ways. In the arrangement shown in the drawing, the spring is formed with a pair of projecting pins or ears 50 which pass through apertures in a generally U-shaped member 5I, so that movement of member 5I will force the spring 48 transversely of the rib 8c for ejecting the lower- The opposite end 52 of the member 5I protrudes outwardly through the wall 2, through an opening 53 provided for this purpose. As will be apparent, pressing on the end 52 of member 5| will urge the spring 46 so as to bring the toe 48 thereof against the boundary of the blade central aperture for forcing the blade transversely of the rib 8c and ejecting it. A bifurcated spring I4c which straddles the rib 8c and ejector operating parts is provided for holding a stack of new blades down onto

ledges

42 and 43.

What is claimed is:

A razor blade magazine comprising an open ended box, a central rib for slidably holding a stack of razor blades by means of central apertures therein, a supporting ledge formed on the lower end 0f the rib for extending under the bottom blade of the stack adjacent one end of the central aperture thereof, a supporting ledge on the box positioned to extend under the opposite end of the blade, spring means for pressing a stack of blades carried by the said rib downwardly onto the said supporting ledges and an ejector positioned for sliding the lowermost blade of the stack held on the rib longitudinally of the rib and olf the ledges so that it may be dropped into a razor.
