I GUILLERMO ANTONIO FARINI of No. 2 Vernon Place Bloomsbury Square London,
Author traveller and Impressario 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 :-
The magazine is so constructed and attached as not to necessitate in cutting or in
any way interfering with the present action except the lever which is jointed close
to the trigger and to which is also attached another lever.
The magazine is upright and is attached to the left side of the gun and all of the
action is attached to it and works between the outer wall of the magazine and that of
the rifle.
The joint in the present lever permits it to describe a larger circle after having
ejected the empty shell which allows the lever that is attached to it to open a catch
and allow a cartridge to fall into position and by a farther forward movement of the
lever the cartridge is pushed into the chamber of the rifle. The return movement
of the lever closes the block ready for firing.
(Fig. 1) Is a side elevation of rifle with magazine in position showing where the
lever is attached to the present one.
(Fig. 2) Is a perspective view of magazine with spring door open, and cogged
cams attached and levers for releasing the cartridges.
(Fig. 3) Shows position of levers and cogged cams when the rifle is ready for
firing.
(Fig. 4) Shows position of lever and cams when the empty shell is thrown out
immediately after the outer lever releases a cartridge, then the cogged cam travels
three eights of an inch before touching the cogged lever that forces the cartridge into
the chamber which gives the cartridge sufficient time to fall into the block that is
then down.
(Fig. 5) Shows position of levers when the cartridge is forced into the bore of
the rifle.
(Fig. 6) Is a cross section showing the end of the magazine, the present lever
jointed and the lever attached to it, the moveable pin that pushes the cartridge into

page_text: its place also ends of springs that forces the cartridges up and out the door when
released and the chain with balls attached to the plate that the springs are
attached to.
(Fig. 7) Shows vertical section with double zig zag springs and cartridge of
another modification of feeding or releasing the cartridges one at a time.
(Fig. 8) Is cross section of (Fig. 7) showing roller at bottom.
(Fig. 9) Underside plan of bottom of magazine with springs and levers in position
for holding the chain and balls.
(Fig. 10) Underside plan of bottom of magazine with springs and levers for holding
and releasing chain from roller.
(Fig. 11) Perspective of cogged lever in detail with sliding pin and spiral spring
for same.
(Fig. 12) Door to magazine with spring hinge and stop action (Fig. 1) represents
the gun in position with a cartridge in chamber, ready for firing, the trigger being
pulled, the thumb is placed on the lover which is pressed down and forward, the
same distance as at present to discharge the empty shell as shown in Fig. 4 lever >>
presses against the bottom of the gun, and is fulcrummed at when the empty shell
is discharged the same as at present. This permits the lever to describe a larger
circle and immediately brings the levere which is jointed to lever at c' in contact
with the lever h (Figs. 2. 9. 10). pressing it down, which pushes up lever k¹ and
draws down the cartridge feeder n by the rod m and allows the cartridge p to be
forced against the door Fig. 12 by the upward force of double zig zag springs i
which door opens and allows the cartridge to fall upon the block and a spiral spring
in the hinge of door as shown in Fig. 12 closes it again, a further movement of the
lever causes the lever c to turn the cogged cam d into gear with cogged cam lever e
which describes a part of a circle and pushes the cartridge into its place with the
pin (Fig. 6) the head of which travels in slotted levere and follows the cartridge
by means of a spiral spring g. The position with cartridge pushed home is shown in
Fig. 5 the return movement of lever c striking the lever h, only pushes it against the
spring (Figs. 2 and 9).
The return movement of the lever b brings the pin fon cogged lever e back into
its former position as shown in Fig. 3.
The spiral spring g keeping the pin fin its position when not in use, as the cam d
and cam lever e do not come into contact until the cartridge has fallen from the
magazine into the block. Another way of releasing or feeding the cartridge is shown
in Fig. 6 which is a cross section of cartridge case. The zig zag springs i are released
the exact distance of the diameter of a single cartridge, the force of which opens the
door and the cartridge falls into position to be pushed into the chamber by pin f.
This is done by means of small levers and springs that open when the lever c touches
the lever Fig. 9 and allows a ball to pass that is attached to a chain and again closes
in time to catch the next ball, the distance between the said balls is equal to the
diameter of a cartridge. This means of positive feed is put into action by the lever 'c
which presses against the lever Fig. 9 (which shows the bottom of cartridge case or
hopper) as it passes and opens the springs ja ball on the chain slips through and the
spring pressing on the lever allows the springs j to close again. The return
movement of the lever e presses the lever against the spring which keeps it in
its place.
Another means of feeding the cartridge is shown in Figs. 7. S. 10 the lever c in
describing its circle touches the lever in Fig. 10 the point of which presses against
the catch that is hinged at which draws the point from the cog on the roller
which allows it to make one turn releasing sufficient chain to permit the zig zag
spring i to force one cartridge through the door 1.
The detail of spring door 7 shown in Fig. 12 is that on the hinge pin is placed a
spiral spring o that closes the door. It is kept open when raised a sufficient height
by sliding back into the slots o¹ by the same spring as keeps the door shut and allows
the magazine to be easily refilled. Fig. 6 shows slide that can be pushed over joint
when using rifle for single firing.

page_text: Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed I declare that what I
claim is
1st. A Magazine attachment to the Martini rifle without cutting any of the present
action save jointing the lever.
2nd. A Magazine with the whole of the mechanism attached.
3rd. A spring door as herein described that shuts itself and prevents the cartridges
from falling out and also from being forced over the block of the rifle when released,
and prevents the cartridge from falling out of position before it is pushed into
the barrel.
4th. A pin sliding in a lever to follow the cartridge by means of a spring as
herein described.
5th. Two cogged cam levers one going in an opposite direction to the other as
herein described.
6th. A double zig-zag spring attached to a plate that the cartridges rest upon
to force the cartridges up, the bottom ends of which are not attached to the
magazine as herein described.
'
7th. Jointing the present lever and attaching another lever to it which permits the
present lever to work the magazine after the empty shell is thrown out.
8th. A slide to cover joint in lever which prevents the magazine coming into action
when the rifle is used for single firing.
9th. The whole of the invention as herein described.
