Description
This invention relates to a cartridge clip for automatic hand guns
and means for quickly and securely attaching the clip to an
auxiliary stock thereby permitting conversion of a hand gun to a
shoulder gun and back to a hand gun as desired by the user.
It is well known that the degree of accuracy normally achieved with
a hand gun such as a revolver or automatic pistol is not as great
as the accuracy obtainable with a rifle or shoulder gun since the
latter can be steadied with both of the user's hands and receives
the support provided by holding the gun against the user's
shoulder.
Efforts have been made in the past to adapt hand guns for use as
shoulder guns; however, the results of such efforts have left much
to be desired so far as safety, simplicity and quickness of
effecting the conversion are concerned. One technique involves, for
example, a stock attached by screws and nuts to the hand gun handle
which results in a more or less permanent attachment of the stock
and gun to each other. Other proposed solutions to the problem
involve the use of a stock member which has a socket or member for
receiving the gun handle in a loose manner which requires the user
to hold the gun in the socket at all times while the gun is being
used in association with the stock.
Accordingly, the primary object of the present invention is to
overcome these disadvantages and provide a cartridge clip for
automatic hand guns which includes means on its bottom wall
permitting a quick, detachable coupling or connection with
cooperating means on an auxiliary shoulder stock device to convert
the hand gun to a shoulder gun.
A further object of the invention is to provide a shoulder gun
conversion arrangement for automatic hand guns which does not
interfere with normal hand use of the gun.
A still further object of the invention is to provide an auxiliary
stock for hand guns which is readily separable for storage when not
in use, is light-weight and inexpensive to manufacture.
Another object of the invention is to provide a safe, positive
connection between a hand gun and auxiliary stock which permits use
and transport of the gun without the likelihood of accidental
separation of gun and stock.
Still another object of the invention is to provide means for
connecting and disconnecting a hand gun and an auxiliary stock in
the field without the use of tools.
With the foregoing and other objects in view which may hereinafter
appear, the invention consists of such parts and combination of
parts as are more specifically described in the following
specification and illustrated in the accompanying drawings,
wherein:
FIG. 1 is a side elevation showing an automatic hand gun with a
cartridge clip of the present invention housed within the gun
handle and connected to the auxiliary stock.
FIG. 2 is an exploded perspective view of the details of the clip
and stock coupling means with parts of the clip and stock broken
away.
FIG. 3 is a side elevation, partly in section, showing the coupling
means of FIG. 2 in assembled position.
FIG. 4 is an end view, partly in section, taken on the line 4--4 of
FIG. 3.
FIG. 5 is an exploded perspective view, partly in section, showing
the clip in position to be assembled with the stock coupling
means.
FIGS. 6 through 9 each are exploded perspective views of modified
forms of coupling means for the clip and stock.
Referring to the drawings in detail, FIG. 1 shows a typical
automatic pistol 1 including a conventional hollow handle 2 adapted
to receive a cartridge clip 3, the lower portion only of which is
shown in FIGS. 2-9 of the drawings. The coupling means attached to
the clip 3 comprises a base member 4 of generally U-shape in cross
section including a bottom wall 5 and a peripheral upstanding wall
6 extending along both sides but only along one end of the base
member leaving the opposite end open. The wall 6 of the base member
is secured by welding, for example, to the bottom 7 of the clip 3
thus providing a space between the clip bottom and the bottom 5 of
the base member for a purpose to be later described. The bottom
wall 5 is provided at the open end of the base member 4 with an
arcuate cut-out area 8 and keyhole slot 9 is located forwardly of
the cut-out area 8.
The auxiliary stock designated generally as 10 is preferably formed
of a light-weight metal and includes a shoulder engaging butt 11 at
one end of an arm 12 extending angularly therefrom, the other end
13 of the arm having coupling means mounted thereon for cooperation
with the coupling means on the base member 4 of the clip when the
stock is assembled with the hand gun. One form of the
aforementioned coupling means is shown to advantage in FIG. 2 and
comprises essentially a saddle 14 of generally inverted U-shape
provided with a pair of spaced threaded openings 15, 15 in its top
wall 16. The spacing between these openings corresponds to that of
openings 17, 17 in the arm 12 of the stock 10. Although only two
openings are shown in the arm of the stock, additional
appropriately spaced openings may be provided for adjustment of the
distance between the gun and the shoulder butt so as to suit
individual requirements.
To attach the saddle 14 to arm 12, it is placed over the arm so
that the threaded openings 15, 15 and related openings 17, 17 are
aligned and then headed threaded fasteners 18, 18 including collars
18', 18' are passed through the aligned openings and are fixed in
the desired fastening position by means of nuts 19, 19. The
fasteners 18, 18 are adjustable vertically with respect to saddle
14 so that the heads 20, 20 can project above the thickness of the
bottom wall 5 whereby, when the base member 4 is placed on the
saddle 14 with the larger portion of the keyhole slot 9 over the
forwardmost fastener head 20, the cut-out area 8 will clear the
head 20 of the rearmost fastener and upon sliding the clip
rearwardly in the direction of the arrow R in FIGS. 1 and 5, the
cut-out area 8 and the narrow throat portion 9a in bottom wall 5 of
the base member will embrace the collars 18', 18' of the fasteners
18, 18 just beneath the heads 20, 20. This arrangement together
with the friction fit between the upper surface of saddle 14 and
lower surface of bottom wall 5 of base member 4 provides a positive
attachment of the hand gun to the stock such that the assembled
members can be safely carried without accidental separation, yet,
they can readily be intentionally separated by holding the stock in
one hand and giving the gun a quick jerk forward with the other
hand. In addition to the built-in frictional engagement between the
opposed surfaces just described, the direction of recoil always
keeps the clip and gun forced back toward the butt 11 to insure a
tight fit between the clip and stock. The threaded fasteners 18, 18
can be adjusted vertically in threaded openings 15, 15 if necessary
to compensate for wear between parts so that it is possible to
further provide for a proper fit between the connected members.
In the modification shown in FIG. 6, a tubular member 20 is secured
to the bottom surface of the clip 3 and telescopically receives the
finger 21 projecting from the end 13 of the stock 10 to provide a
frictional fit between the clip and stock.
FIG. 7 illustrates a coupling means whereby the clip 3 has an
inverted T-shaped member 21 secured to its bottom surface. This
member 21 is inserted into a generally flat tubular socket 22
mounted at the end 13 of stock 10 to frictionally connect the clip
and stock. The socket 22 is formed of a strip of sheet metal
provided with a slot 23 in its top wall, one end of the slot being
open to receive the vertical web 24 of the inverted T-shaped
member, the other end of the slot being closed by stop members 25,
25.
FIG. 8 shows an embodiment wherein the base of the clip 3 is
provided with a T-shaped groove 26 adapted to frictionally receive
a tongue 27 formed on the end 13 of the stock 10.
FIG. 9 illustrates a further embodiment wherein the end 13 of stock
10 is provided with an elongated recess 28 in one side thereof
which communicates with a slot 29 in the top wall of end 13. A
lever 30 includes a nose 31 at its front end, an arm 32 medially
thereof, a finger grip 33 at its rear end and is pivotally mounted
in the recess 28 by means of a pin 34 passing through an opening in
arm 32. A coil spring 35 has one end fixed in the side wall of
recess 28 and its other end is attached to lever 30 along the inner
edge opposite the finger grip 33 and in its extended or normal
position the spring urges the lever to rotate around pivot pin 34
so that nose 31 is disposed within recess 28 and beneath slot 29.
The bottom wall 5 of clip 3 is provided with an elongated plate 36
normal to and depending therefrom, said plate having an opening 37
large enough to accommodate the nose 31 of the lever. To connect
the clip to the stock it is merely necessary to press the finger
grip 33 inwardly against the tension of spring 35 which causes nose
31 of lever 30 to move out of recess 28. The plate 36 is then
inserted into slot 29 so that bottom wall 5 of the clip is flush
with the top surface of the stock 10. Upon release of pressure on
finger grip 33, lever 30 will pivot under the urging of spring 35
causing nose 31 to pass through opening 37 thus locking the clip in
position. If desired, cooperating camming surfaces would be
provided at the bottom edge of plate 36 and at the inner edge of
nose 31 whereby the nose would be cammed out of its inoperative
position when initially engaged by the surface of plate 36 and the
inner edge of the nose would snap into opening 37 when the clip and
the end of the stock are in full contact position. The connected
members could readily be separated by pressing the finger grip
inwardly against the tension of the spring which would remove the
nose 31 from engagement in opening 37.
In all of the embodiments described above and illustrated in the
drawings, the connecting means attached to or forming part of the
clip is such that it does not interfere with use of the clip in the
automatic gun in the usual fashion apart from the auxiliary stock
member. Said connecting means may, when appropriate, be formed
integral with the clip or it may be attached thereto by welding
techniques or by use of structural adhesives such as epoxy
resins.
It is within the scope of the invention to dispense with the saddle
member 14 as shown in FIGS. 1-5 and merely use fasteners 18 and
nuts 19 as the coupling means on the end 13 of stock 10. In such a
case, it would be preferable to have the openings 17, 17 threaded
so as to provide vertical adjustment for the fasteners.
