Improvements in Breech-loading Small Arms.
We, DOUGLAS VAUGHAN JOHNSTONE, of 8, Whittall Street, in the City of
Birmingham, Gun and Rifle Maker, and LESLIE BOWN TAYLOR, of 129, Pershore
Road, Birmingham, aforesaid Gun & Rifle Maker, do hereby declare the nature
of this invention to be as follows:-
This invention refers to improvements in the breech actions of Martini rifles &
the like & has for its object an improved means of detaching the interior mechanism
from the box or shoe for the purposes of cleaning or repairing.
We will describle this our invention as applied to an ordinary Martini rifle
action.
Instead of using the ordinary extractor axis pin, indicator or tumbler axis pin,
& block axis pin, we form the three axes by means of studs upon a thin plate
attachable on one side or the other of the mechanism.
We form on the guard frame an upright bar to fit against the block to keep it
in position when out of the box or shoe.
The studs may be made hollow right through to receive pins from the exterior
of the shoe, but we prefer to dispense with the block pin & to secure the interior
mechanism in the box or shoe by means of exterior pins in the extractor & tumbler
holes.
By cocking the arm & removing these two pins the interior mechanism together
with the plate to which it is attached may be entirely removed from the box or
shoe & the whole mechanism may be detached in detail from its plate by simply
pulling the trigger to release it from the tumbler bent.
As in this mechanism we do not employ the ordinary indicator on the side of
the shoe, we use an indicator on the shoe or box worked by the back of the block.

page_text: Road, Birmingham aforesaid, Gun and Rifle Maker, do hereby declare the nature
of this invention and in what manner the same is to be performed, to be par-
ticularly described and ascertained in and by the following statement:-
-
This invention refers to improvements in the breech actions of Martini rifles
and the like, and has for its object an improved means of detaching the interior
mechanism from the box or shoe for the purposes of cleaning or repairing.
We will describe this our invention as applied to an ordinary Martini rifle action.
Tustead of using the ordinary extractor axis pin, indicator or tumbler axis pin,
and block axis pin, we form the three axes by means of studs upon a thin plate
attachable on one side or the other of the mechanism. We form on the guard
frame an upright bar, to fit against the block to keep it in position when out of
the box or shoe. Or we may in some instances dispense with this upright bar.
The studs upon which the extractor, tumbler, and block pivot may be made
hollow right through to receive pins from the exterior of the shoe or we may
dispense with the block pin and secure the interior mechanism in the box or shoe
by means of exterior pins in the extractor and tumbler holes, or we may dispense
with the tumbler pin and secure the mechanism by means of the other two.
By cocking the arm and removing these two pins the interior mechanism,
together with the plate to which it is attached may be entirely removed from the
box or shoe and the whole mechanism may be detached in detail from its plate
by simply pulling the trigger to release it from the tumbler bent.
As in this mechanism we do not employ the ordinary indicator on the side of
the shoe, we use an indicator worked from the back of the block, but we make no
claim of novelty for any such arrangement.
We will refer to the accompanying sheet of drawings to assist in the description
of this our invention.
Fig. 1 is a view of the box or shoe which contains our improved Martini action.
Figs. 2 and 3 are views of the mechanism in its varying positions.
Fig. 4 is a view of the plate for carrying the mechanism in position.
Fig. 5 is a sectional view of same.
Fig. 6 is a view of the guard.
Figs. 7, 8, 9, and 10 are views of the various limbs of the mechanism detached
from the carrying plate.
And Fig. 11 is a view of one of the pins.
A is a stud forming the block axis pin.
Bis a hollow or tubular stud forming the tumbler axis, and C is a similar one
forming the extractor axis.
The pins E Fig. 1 which hold the mechanism in the shoe S pass through these
hollow studs B and C and screw into the other side of the shoe S which is tapped
to receive them.
We form on the guard frame F an upright arm G Figs. 2, 3 and 6 which fits
against the block H to assist in-keeping it in position when removed from the
shoe S. The block H is recessed at H' to allow of it passing this upright arm G.
N Fig. 1 shews the indicator in its cocked position.
By depressing the lever I as shewn in Fig. 3, and removing the two pins D, E,
Fig. 1, the interior mechanism together with the plate % to which it is attached
may be entirely removed from the box or shoe S and after the mechanism is
removed from the shoe S, the pulling of the trigger P to release it from the tumbler
bent Kenables the block H, the tumbler K, the lever I, the extractor L, and the
guard Fall to be detached in detail from their plate Z as shewn in Figs. 6, 7, 8, 9,
and 10.

Having now particularly described and ascertained the nature of our said in-
vention and in what manner the same is to be performed we declare that what
we claim is :-
(1) In Martini rifles and the like the use of a removable plate to carry the

page_text: 2. In Martini rifles and the like the use of a plate with studs constructed so as
to enable the block, the extractor, the tumbler, the lever, and the guard to be
entirely separated by hand from the plate.
