What is claimed is:
1. A razor blade ‘dispensing magazine comprising, in

Adjacent its side edges, wall 21 has ribs 28 projecting
cooperably providing a pair of spaced walls, parallel over

a substantial portion of their length, and arranged to form

access opening therein; a pair of posts on the inner sur

face of said one section rearwardly of said access opening
nearest wall 11 is spaced from wall 11 by about 0.005".
and laterally spaced to receive the reduced end of a blade
Before assembly of section 20 to ,section 10, the latter

FIG. 10, strips ‘45 have holes 47 receiving posts 17 and
have U-shape recesses 46 in their forward edges con
forming to opening 15. Strips 45 terminate somewhat
short of the forward ends of blades 40. The stack of

a stack of blades positioned in said magazine against said
Plate 30, best seen in FIG. 8, is then placed on the
blades with holes 36 receiving pins 17 and slot 37 aligned
with the slots in blades 40. Then bowed spring 35 is
smooth inner surface and with their reduced ends between
said posts and said lug engaged in their slots for lateral
placed on top of plate 30 with its rear edge engaging
posts 17 and its slot 34 aligned with slot 37. The length
and width of slot 34 controls the ?exibility of spring 35.
With slot 34- toward the front, the spring tension toward
the forward ends of the blades is increased relative to the
spring tension toward the rear ends. The spring as a
whole is nearer the rear end of the blade and Strip stack
than it is to the front end thereof, thus pressing the stack
guiding and positioning of said blades; paper separator
strips disposed between the blades and each having a pair
of holes receiving said posts; the forward ends of said
strips terminating intermediate the ends of said access
opening and having recesses conforming to the margin of
said access opening; and spring means engaged between
said other section and said blades and pressing said blades
toward said one section; said blades being discharged by
pressing the blade, exposed through said access opening,
toward wall 11 as a blade 40 is slid out of the front end
inwardly and forwardly, and, during discharge of the
of the magazine.
Following positioning of spring 35, side walls 13 are
spread slightly and section 20 is snapped into place in
?rst few blades, the forward end of each blade being dis
grooves 31 with lips 33 engaging in recesses 32. Ribs 23
bear against the edges of the convex surface of spring 35,
thus maintaining the spring pressure on the stack. Lug
or book 25 enters .slot 37 and the slots in blades 40 and,
depending on the compression of spring 35, may also enter
partly into slot or notch 34.
To eject a blade, pressure is exerted on the blade
through opening 15, and the blade is slid forwardly. Dur
ing this movement, the front end of the blade engages
and moves along the curved surface of wall 11, tilting the
blade so that it remains engaged with lug 25. The rear
end of the blade slot rides along bevelled surface 27 and
charged riding inwardly along the inwardly extending part
of the inner surface of said one section to tilt the blade
to maintain the latter in guiding engagement with said lug
as the rear end of such blade rides between said lug and
the inner surface of said one section; said strips being re~
tained in said magazine and, after the ?rst few blades
have been discharged, forming a bearing surface for the
blades sui?ciently thick that the remaining blades, during
discharge, are not tilted by engagement with the inner
surface of said one section.

pressure plate between said spring means and said blades
and having a pair of holes engaged with said posts and
a slot receiving said lug.

3. A magazine as claimed in claim 2 in which the clear
The thickness of the paper strips is 0.004". Thus 75 ance between said lug and said one section is of the order

of 0.005" and the thickness of said strips is of the order
of 0.004".
4. A magazine as claimed in claim 2 in which said
spring means comprises a bowed spring having a convex
surface; laterally spaced ribs on the inner surface of said 5
other section engaged by said convex surface; said spring
having ends engaging said pressure plate, the forward end
of said spring ‘being centrally notched to increase the
?exibility thereof relative to the rear end of the spring
and to embrace said lug; the rear end of said spring 10
engaging said posts.
