SAFETY RAZOR AND BLADE MAGAZINE

This invention relates to a magazine for dou
ble-edge safety razor blades and means whereby
blades to hold the rear of the cutting edges out
of contact with the side walls of the magazine,
and also provide a vertical guide rib along the
inner face of the front wall extending within
the blade slots to hold the forward ends of the
cutting edges away from the side walls. As the
forward guide must stop short of the discharge
such a magazine can be mounted on the razor to
inject a new blade while simultaneously ejecting
a dull one. Magazines for double-edge blades
have been proposed, but always, so far as I am
aware, for use in connection with razors of spe
cial construction which are unnecessarily com

the underface of the top 3| of the magazine, acts
to center the blades, including the topmost one,
particularly at their forward or open-slotted ends.
The rear projections 48 on the blades engage the
corner blocks 35, as illustrated in Figures 5 and 6,
and the guide rib 36 extends into the blade slots,
20 and thus the blades are spaced from the side walls
of the magazine and their cutting edges pro
tected.
The slide 152 is just wide enough to ?t within
the projections 48 along the rear edge of each
blade. Thus when the slide has been retracted to
