Improvements in Cartridge Holders.
I, EUGEN BREUNING, of Oberndorf on Neckar, in the Empire of Germany,
Mechanician, do hereby declare the nature of this invention and in what manner
the same is to be performed, to be particularly described and ascertained in
and by the following statement:-
This invention has for its object a cartridge holder for loading in which the
fixing of the cartridges in the loading holder takes place by means of springs
or more separate
and in which each cartridge is held independently by one
springs in such a way that no cartridge lies loosely in the holder. The springs
are also so arranged that on the insertion or withdrawal of the cartridges, the
latter experience during their whole course an equal resistance.
In the loading holders at present employed although separate springs are
inserted in the holders, no pressure on each separate cartridge by means of
these springs takes place, but a portion of the cartridge always lies loosely in
the frame causing an uneven ejection of the cartridges from the frame or holder
and necessitating a projecting position of the cartridges in the holder. These
drawbacks are entirely avoided in this improved loading holder.
In the accompanying drawings Figs. 1-14 show this improved cartridge
holder, Figs. 1 to 3 showing it with cartridges inserted.
Figs. 4, 5, 6, 7 and 8 are plan views in which the springs formed by partial
stamping out in the bottom of the holder are shown in different forms of con-
struction as examples.
Figs. 10 to 14 are cross sections and longitudinal sections respectively on an
enlarged scale of the loading holder.
Cartridges are held in loading holders as is wellknown by the projecting edge
of the bottom of the cartridge being pressed by a spring against the upper bent
over edges of the holder or frame.
C
In the present invention this is effected by springs c¹² being formed
by a partial stamping out of the bottom of the loading holder b and bending up
of the stamped out parts, which springs lie in such a way that each separate car-
tridge a is pressed against the edges of the holder by means of one or two
springs c, c, c², c³, lying directly beneath it and the springs c, c¹, 2, 3,
are so formed that during the insertion or withdrawal of the cartridge a it is,
during its entire course equally pressed against the edges b¹ of the holder always
by one or, if preferred, two springs c, c1, c2, c³, or c.
The springs may be of any suitable form. For instance in Fig. 4 two rows
of springs are formed stamped out in wavy lines of which alternately the
two outer or inner parts of the corrugations are used for pressing the separate
cartridges against the edges of the holder.
An I shaped groove dd may be impressed in the frame for strengthening
it, the elongated or longitudinal part d of said groove lying in the centre of the
frame or holder.
Fig. 5 shows a holder in which the springs c¹ are formed of a single wavy
stamning out.

page_text: Fig. 6 shows a holder, the springs of which consist of two wavy stampings
out so that the central cartridge is held by two springs .
In Fig. 7 the stamping out of the springs is shown in a continuous rectangular
form.
Finally Fig. 8 shows a holder the springs of which are stamped separately
out of the centre of the bottom.
In the holders 6 shown in Figs. 5, 6 and 7, strengthening grooves are formed
extending all round the bottom of the holder for increasing its resistance, but
this is not absolutely necessary. Preferably however cross grooves, resembling
the grooves d of Fig. 4 are provided at both ends of the holder 6', in order
that the two outermost cartridges may have a better hold.
All the springs c, c¹, c², c³, c4 stamped out are so domed or bulged that the
stamped edges lie somewhat countersunk or depressed and the bottom of the
cartridges inserted or withdrawn cannot catch on these edges.
Of course the springs ccccc may be stamped out in other suitable shapes
so long as they fulfil the object of the present invention namely to provide for
each cartridge one (or more if desired) separate springs for pressing it on the
edge of the holder, said springs being stamped out of the bottom of the frame,
all forms of springs suiting the requirements.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is:-
A loading holder for cartridges characterized by springs of suitable form being
formed by partial stamping out in the bottom of the holder, which springs have
such a position that each cartridge is pressed separately by means of one or
more springs against the holder and the springs oppose a constant even resistance
to the cartridges during their insertion in or withdrawal from the holder, sub-
stantially as described.
