stock element is in the form of an elongated hol
low body 2 having an up-turned forward end. 10
The body 2 provides a magazine 3 designed to
carry forty cartridges. A clip for holding forty
cart-ridges for reloading is indicated at 4 (Fig
ure 20). It is to be understood however, that
the capacity of the magazine 3 may be as desired 15
and that the capacity of the clip 4 may be other
than that as stated. The capacity of the maga
zine preferably is always greater than that of the
magazine of the pistol. When it is deemed
necessary to ?re more cartridges than the pistol 20
carries, as regularly manufactured, the operator
removes the magazine from the pistol and inserts
pistol whereby the larger number of cartridges
carried by body 2 will successively and automati 25
cally be supplied or fed, by a means to be herein
after described, to the pistol to be ?red. In this
connection attention is directed to Figure 2. The
forward end of body 2 isnotched, as at 5, for the

transmitting shaft 66 which is driven from a
- spring motor 61 arranged within a revoluble drum
68 disposed in chamber 4|. The drum 68 revolves
about shaft 66.‘ The motor '61 is in the form of
a windable and unwindable coiled power trans
mitting spring 69 which encompasses and has-one
end fixed to shaft 66. The spring 69 has its other
end ?xed to drum 63. The latter is arranged be
tween the vcaps 62, 63, abuts the boss 65 on cap
10 62 and is spaced from the boss '65 on cap 63. The
sides of the drum 68 are axially apertured, as at
18, for the passage of shaft 66. Interposed be
tween drum 68 and the boss 65 of cap 63, as well
as being ?xedly secured to shaft 66 to bodily move
15 with the latter, is a grooved power transmitting
pulley 1|. The body of drum 68 has its outer pe
riphery formed with a pair of spaced annular
ribs 12 to form the drum 68 with a circumfer
ential groove 13. The cut out top 48 of the rear
20 terminal portion of element-39 forms a clearance
for the bottom of drum 68.
Winding off and on the drum 68, relative to
groove 13, is a ?exible pulling element 14 upon
which is attached a ?exible cartridge pusher or
25 feeding device or mechanism 15. The element 14
is of strap or tape-like form and has one end at
tached to drum 68 within groove 13. The ele
~ment 14, when winding off the drum 68, travels
through the element 39 to cause the device 15
30 to feed the cartridges. The element 14 winds on
the drum 68 on the return of the device 15 to its
initial position. The element 14 travels from the
rear portion of chamber 4| into and through the
element 39 and from the latter into the forward
35 end of and rearwardly in chamber 4| on the feed
ing of the cartridges. After all the cartridges
have been shifted into the part 8 of the stock 2,
the device 15 is shifted rearwardly relative to
element 39 and element 14 is returned to the full
40 line position shown in Figure 11. The rearward
shift or travel of element 14 relative to element
39 is provided by the winding up of the spring
motor 61 by a means to be referred to.
The device 15 consists of a curved leading car
45 riage 11 provided with a friction roller 18 pro
tion rollers 15, 8| bear against the inner face
of the device 85 when the device 15 is in the po
sition shown in Figure 10. The band 81, on its
outer face, has a protuberance 89 for engaging
stem 51 and rocking member 54 to move hook
56 clear of nose 53 to permit spring 5| to shift
door 48 open so that access may be had to the
rear end of magazine 3 to enable the loading of
the latter with cartridges. When the device 15
is moved from the position shown in Figure 10 10
it carries the band 81 therewith in a direction
to have protuberance 89 clear shank 51 whereby
member 14, due to spring 6|, will be carried with
device 15 until its edge 98 arrives at the closed
portion 9| of the channels 35, 36. At this point
a spring controlled latching device 92 will engage
the edge 93 (Figure 10) of band 81 and act to pre
vent the latter being shifted accidentally in the
other direction until it is moved in such direction
on the return of the device 15 to its initial posi 20
tion. The device 92 is arranged forwardly of
band 81 and is mounted at one end on a pivot 94
carried by plates 21, 28. The controlling spring
of device 92 is indicated at 95. The device in
cludes a curved offset portion 96 to engage edge
93 of band 81. The device 92 is arranged in
chamber 4|. On thepreturn of the device 15 to
its initial position (Figure 4) the pusher mem
ber 19 engages the projection 88 and causes the
band 81 to move from the position shown in Fig 30
ure 10 to that shown in Figure 4.
As the band
81 is moved by the pusher member 19, the pro
tuberance 89 will ride against shank 51 and will
release and hold latching member 54 in released
position relative to nose 53, and in this connec
tion attention is directed to Figure 4.
The pulling element 14, when operating to pull
the device 15 for the purpose of feeding the car
tridges, is wound on a winch 91 which is operated,
during the ?ring of the gun, from the pulley 1| 40
by a power transmitting strap 98. The winch
91 includes means for driving the strap 98 for the
purpose of operating the pulley 1| in a direction
for winding up the spring motor 61 and thereby
unwinding the element 14 from oif the winch and 45

The shaft 66 is connected with the winch 91 in
a manner whereby the latter will be operated in
an anticlockwise direction from said shaft 66
61. The shaft 66, when operated from said motorv
61, moves in a clockwise direction. Due to the
diameters of the pulleys 1I, I04 relative to each
other and the diameter of the drum 68 being
greater than that ofpulley 1I, there is a dif
ferential ratio set up which causes the winch 91
25 to wind thereon the pulling element 14, thus
pulling the device 15 into the magazine and dur
ing such action the motor 61 operates shaft 66 in
a clockwise direction and provides for pulling
the element 14 from off drum 68 at a slower speed
80 than that of shaft 66. When the feeder or pusher
device 15 has traveled to the front end of the
magazine 3,‘ the handle I21 is extended and oper
ated in a direction to rotate shaft II6 to an ex
tent to provide for collar I22 clutching the drum
35 IIO of winch 91 to shaft II6. When winch 91 is
coupled to shaft II6 the handle I21 is turned in
a clockwise direction carrying shaft H6 in a like
direction whereby the drum III] and pulley Hi4
are revolved by shaft I I6 in a clockwise direction
'40 whereby the transmission strap 98 will operate
disposed strap-like segmental shaped members
I11, I18 of like form. Each of said members in
cludes a narrow lower part I19 of inwardly open

part I80 of inwardly opening channel-shape form 25
of greater width than part I19 and having its
inner flange I8I of less width than its‘ outer ?ange
I82, an upper intermediate part I83 of inwardly
opening channel-shape form of greater width
than the part I19 and having its inner and outer 30
?anges I84, I85 respectively of the same width,
an upper terminal part I86 having its lower edge
grooved as at I81 and of greater width than part
I19, and a lower terminal part I88 formed in its
rear edge with a groove I88"L and of greater width
than part I19. The part I88 merges into the
lower end of part I19. The part I80 merges into
the upper end of part I19. The part I83 merges
into the upper end of part I80 and the part I86
merges into the upper end of part I83. The part 40

than the parts I80, I81, I88. The parts I80, I81,
I66 is carried by the extension 29 of plate 21 and
coacts with the teeth II5 to arrest the winch
45 moving anticlockwise when shaft H6 is operated
clockwise from the handle I21. When the winch
91 is operated in a clockwise direction it unwinds
therefrom the pulling element 14 and permits the
element 14 being wound on drum 68 to an extent
50 to shift the device 15 from out of the magazine 3
into the chamber 4| and around drum 68 to the
position shown in Figure 4.
Any suitable means may be employed for latch
