Description
Cartridge magazines for firearms may be of the detachable type or
they may be built into the firearm assembly. The detachable type is
commonly used with military firearms and it is also widely employed
for hunting and sporting firearms. Many cartridge magazines,
whether detachable or built-in, can be filled with cartridges from
stripper clips, a method which appeared many years ago. To use the
clips with a detached magazine some simple type of guide is
necessary. For the built-in type of magazine the guide is usually
formed as part of the firearm. A few firearms with detachable
magazines are arranged for filling the magazine from clips when
either attached to, or detached from, the firearm.
This invention will be useful for those types of magazines, whether
detachable or built-in, which can be filled by stripping cartridges
from a clip.
The successful use of the above-described filling methods depends
on the correct support of the clip while the cartridges are
stripped from it into the magazines. This requires a proper
relationship between the dimensions and configuration of the clip,
the guide, and the magazine.
Clips suitable for a given cartridge do not always have the same
dimensions and configuration. Changes introduced by various
producers may result in making the clip compatible with only
certain types of clip guides, and not with others. For example,
substitution of plastics for metals will usually require
dimensional changes which may prevent use of the clip in cartain
clip guides. However, metallic clips also vary considerably, as is
well known.
Cartridge magazines also vary somewhat in configuration and
details. A clip guide intended for filling one model of magazine
frequently cannot be used for filling others, even though the
several magazines may be intended for the same cartridge.
In view of the considerable variety of clips, cartridges and
magazines available at the present time, it is desired to point out
that the utility of the present invention is not restricted to any
particular combination of clip, cartridge, and magazine. The
illustrations are for purpose of disclosure, and are not to be
considered as limiting the usefulness of the invention.
A principal object of this invention is to provide a clip holding
guide which will permit the use of two or more dissimilar types of
stripper clips for filling a conventional cartridge magazine.
Another object is to provide a clip holding guide which will permit
the use of dissimilar clips for filling two or more different
cartridge magazines.
These and other objects of the present invention will be apparent
upon reference to the following specification, taken in connection
with the accompanying drawing, wherein:
FIG. 1 is a perspective view of a clip holding guide which is an
embodiment of this invention, affixed to a typical cartridge
magazine.
FIG. 2 is a perspective view of another embodiement of this
invention, having different means for affixing it to a
magazine.
FIG. 3 is a perspective view of another embodiement of this
invention.
FIG. 4 is an elevation view of still another embodiement of this
invention, for use with a plurality of clips and a plurality of
magazines.
FIG. 5 is a view, partly in section, of means on a clip holding
guide to slightly depress the follower of an empty cartridge
magazine.
FIG. 6 is a perspective view of the receiver of a firearm, having a
plurality of slots which serve as clip holding guides for filling
the magazine.
Referring now to the drawings in detail, FIG. 1 shows a typical
cartridge magazine 1, having feed lips 3 and 5 and stiffening
grooves 7 and 9 in each sidewall. (Only one sidewall is visible in
FIG. 1.) The construction of typical magazines is well known and
need not be further detailed here.
Affixed to magazine 1 is clip holding guide 11 which has three
channel clip supports 13, 15 and 17. Clip supports of the channel
type are well known and need not be further described here.
The lower portion 19 of guide 11 also comprises a channel, with
edges turned inward so as to engage grooves 9, on each side of the
magazine. A suitable detent (not shown) may be provided to limit
the distance which guide 11 slides down on magazine 1. Stripper
clips usually are made with small projecting stops to limit the
extent to which the clips can be inserted into a support such as
channel 13, 15, or 17. In making a guide for clips with such stops
it will be necessary to so select dimensions of the clip support
channels that the clip will be positioned at a proper distance from
the feed mouth of the magazine. In FIG. 1, the feed mouth is the
space between feed lips 3 and 5.
It will be noticed in FIG. 1 that clip support channels 13, 15, and
17 converge toward the extension of the center line of said feed
mouth. When cartridges are stripped from clips supported in any of
the three clip support channels they will therefore be pushed into
the magazine via said feed mouth.
Each of the clip support channels can be made to accommodate a
different clip. There is an increasing tendency to substitute
plastics for metals in expendible military items such as clips, but
of course, this requires dimensional changes. Depending on details
of the magazine to be filled, a clip holding guide of the type
shown in FIG. 1 can be made with two or three clip supports.
If an even greater number of different clips must be accommodated,
the arrangement shown in FIG. 2 may be used. FIG. 2 shows a clip
holding guide 21, comprising a collar 23, and a plurality of clip
support channels 25, 27, 29, and 31. Channels 25 and 27 are
positioned at one end of the collar, while channels 29 and 31 are
positioned at the other end of the collar. The dimensions and shape
of the collar are so chosen that it can embrace the magazine with
either pair of channels at the rear of the magazine. A suitable
stop (not shown) can be provided, if necessary, to limit the
distance which guide 21 can slide down on a magazine.
Clip support channels 25, 27, 29, and 31 can be made so as to
accept various clips. The filling of a magazine using clip guide 21
is similar to the method already described for clip guide 11, with
the exception that it is necessary to choose which orientation will
be necessary, as guide 21 can be affixed to a magazine with either
pair of clip guides at the rear, or stripping, position.
A guide of the type disclosed in FIG. 2 can also be adapted to
accommodate cartridges supplied without clips, that is, loose
cartridges. For example, support channel 31 can be so dimensioned
as to serve as a guide for the head or base of the loose
cartridges. At the same time, support channel 27 can guide the
points of said cartridges. Together, the two can constitute a
hopper for filling the magazine with loose cartridges by pressing
them down through the mouth of the magazine. It is apparent that
the long inside dimension of the collar would be slightly greater
that the corresponding exterior dimension of the magazine, which
usually is slightly greater than the overall length of the
cartridge for which it is adapted. The distance between the two
support channels is therefore approximately the same as the overall
length of the appropriate cartridge.
In some instances it may be possible to so design collar 23 as to
make guide 21 compatible with two or more different magazines.
FIG. 3 shows another arrangement, which can accommodate two clips
to two magazines. A clip guide 33 is made with two channel portions
35 and 37 for attaching the guide to magazines in the manner
described for guide 11 in FIG. 1. It also has a central clip
support 39 and additional clip support channels 41 and 43, each at
an angle relative to support 39.
Assuming that guide 33 is affixed to a suitable magazine by channel
portion 37, a stripper clip can be inserted from above in the usual
manner as indicated by the broken lines and numeral 45, the clip
being supported by central clip support 39.
While the guide is so affixed to a suitable magazine a clip could
be inserted into clip support channel 41 which can be made so as to
accept a different clip from that accepted by central clip support
39.
Guide 33 can be used with a second, different type of magazine. The
guide can be inverted and affixed to the magazine by channel
portion 35 which engages the magazine. A clip can then be supported
in central clip support 39, or a different clip can be accommodated
by clip support channel 43, which might be made to accept the same
clip as does channel 41. Of course, other combinations are also
possible.
Clip holding guide 47 shown in FIG. 4, can be used with a plurality
of clips and with a plurality of magazines. Disposed in an arc on a
generally flat base 49 are a plurality of different channels 51,
53, and 55 by which the base can be affixed to various suitable
magazines. Pivoted relative to base 49 by rivet 57 is plate 59,
which carries a plurality of convergent clip support channels 61,
63, and 65 each of which can be made to accommodate a different
clip.
In FIG. 4 it will be noticed that clip supports 61, 63, and 65 are
alined with magazine attaching channels 51, 53, and 55
respectively. If plate 41 should now be rotated so that clip
support 61 is positioned as indicated by the broken lines at
numeral 61A, it is readily apparent that clip supports 63 and 65
would then be alined with magazine attaching channels 51 and 53
respectively.
If however, plate 41 should be rotated so that clip support 65 is
positioned as indicated by the broken lines at numeral 65A, then
clip supports 61 and 63 would be alined with magazine attaching
channels 53 and 55, respectively. If the plate be further rotated
other alinements are possible.
Of course, some suitable detent can be provided to prevent relative
movement between the parts when the guide is in use. The guide is
affixed to a suitable magazine by one of the channels 51, 53, or
55, and then a clip can be inserted into a suitable support, either
61, 63, or 65, which will then be alined with the channel on the
magazine. Cartridges can then be stripped from the clip in the
usual manner.
Although not shown in the drawings, it is readily apparent that the
relative motion in the embodiement in FIG. 4 could be sliding
motion instead of pivoting, or rotary motion.
In filling a cartridge magazine by stripping cartridges from a clip
it sometimes happens that the initial resistence offered by the
spring-loaded magazine follower makes stripping difficult. The
arrangement shown in FIG. 5 eases this difficulty. The clip guide
67 is affixed to a magazine casing in contact with its rear wall
69. Within the casing are the usual cartridge follower 71 and
follower spring 73. Guide 67 has a stud 75 which contacts the rear
edge of follower 71 as the guide is affixed to the empty magazine
in the usual manner by sliding it down on the casing. Although the
follower is depressed only slightly, much less than the diameter of
a cartridge, the stripping of the first cartridge is thereby made
considerably easier. The distance the follower is depressed is
indicated by the slight gap between guide 67 and rear wall 69.
FIG. 6 shows a typical firearm receiver 77 having an integral box
magazine 79 below it. The receiver also has two clips slots 81 and
83 which converge toward the mouth of the magazine, within the
receiver. The slots can be made to accommodate different clips.
Filling of the magazine is accomplished in the wellknown manner by
inserting a clip in either slot and stripping cartridges from it
into the magazine.
