IIUIDIONAL DILTIVATION.
Improvements in Martini and other Breech Loading Fire-arm
Mechanism.
We, CARL BENJAMIN ENGELS and WILLIAM FIELD, both of 58, Cambridge
Street, in the City of Birmingham, Manufacturers, do hereby declare the nature
of this invention to be as follows:
This invention relates to improvements in Martini and other breech loading
fire arm mechanism that are constructed upon the same lines, part of which
improvements may be applied to other breech loading fire arms, and its primary
object to provide improved means whereby the whole of the internal mechanism
in the action body may be secured in position by one pin, so that by the removal
of this one pin such mechanism may be readily withdrawn for inspection, clean-
ing &c., or what is generally known as stripping or dismounting, without inter-
ference of strength or arrangement of moving parts, and in such a manner that
when thus removed, the lever, tumbler, trigger guard and its body, and the
extractor shall be connected together as a whole, and thus avoid the danger of
losing loose parts when cleaning the gun; also that the breech block with its
striker &c. shall be removable in a similar manner as another part, independently
of the first part; also to provide improved indicator mechanism for showing
whether firing has taken place.
In order to secure the breech block in the action body, instead of the usual
fulcrum pin (at its rear end) we provide upon one or both of the insides of the
action body a stud or projection, part circular in shape, that is having opposite
flats made thereon. These studs form the trunnions or pivots upon which the
breech block shall oscillate. In the sides of the block, holes are made to corre-
spond with and in which the aforesaid studs shall moveably fit. These holes are
further provided with an opening or slot, so that in one position the block may
be slid over the narrowed parts of the studs. Having thus been passed on to the
studs however until the latter are fair with the hole the block may oscillate
thereon, but only in the position before-named can it be withdrawn.
Referring now to the trigger guard body with the lever, tumbler and extractor,
the extractor is carried upon a pivot pin which extends from outside to outside
of the trigger guard body. Forward of this and projecting from the trigger
guard body is a peg or pegs of any suitable shape which shall fit into a corre-
sponding hole or recess in the forward part of the action body, as for instance
extensions may be made on the two sides of the trigger guard body, and two
holes in the action body, or one central extension may be formed upon or attached
to the one which shall fit into the other. Thus having first passed the breech
block into position as before described, and then first passing the forward end
of the trigger guard into position the rear end may be raised until the one
securing pin may be passed through the side of the action body, and through
the tubular pin in the trigger guard body and screwed, when the whole will be
completely fixed in working order. By the removal of this one pin of course
the reverse actions may be done and the whole stripped.

page_text: At the rear end of the action body we provide our improved indicating
mechanism which consists of a slide under spring action, whose inner end is
operated by the striking bolt in the breech block so as to push forward the said
slide when the hammer or striker is cocked-so as to expose it externally to
view, but whose spring shall cause it to pass inwards from view, when the gun
has been fired. The feature of this our improvement being, that such an
indicator is fixed in position from the interior of the body by a screw nut which
secures the pin slide and spring, leaving the exterior free and undisturbed.

Improvements in Martini and other Breech Loading Fire-arm
Mechanism.
We, CARL BENJAMIN ENGELS and WILLIAM FIELD, both of 58, Cambridge
Street, in the City of Birmingham, Manufacturers, do hereby declare the nature
of this invention and in what manner the same is to be performed, to be particu-
larly described and ascertained in and by the following statement:-
This invention relates to improvements in Martini, and other breech loading
fire arm mechanism that are constructed upon the same lines, and its primary
object is to provide improved means whereby the whole of the internal mechanism
in the action body may be secured in position by one pin, so that by the removal
of this one pin such mechanism may be readily withdrawn for inspection, clean-
ing &c., or what is generally known as stripping or dismounting, without inter-
ference of strength or arrangement of moving parts, and in such a manner that
when thus removed, the lever, tumbler, trigger guard and its body, and the
extractor shall be connected together as a whole, and thus avoid the danger of
losing loose parts when cleaning the gun; also that the breech block with its
striker &c. shall be removable in a similar manner as another part, independently
of the first part.
In order to facilitate the explanation of our invention we have appended
hereunto illustrative drawings upon which are figures and numbers of reference.
Fig. 1, is a general side view of the method of carrying out this our invention;
Figs. 2 to 6 being details of the same in which, Fig. 2, is a sectional view on
line A-B Fig. 1; Fig. 2, is a side view of one of the studs within the action
body that serve as trunnions or pivots for the breech block.
Fig. 3, is a side view of the breech block.
Fig. 4, is a sectional view on line CD Fig. 3.
Fig. 5, is a general side view of the trigger guard body lever, tumbler &c.,
as a whole and apart from the action body.
Fig. 6, is a detail view of the one securing pin.
We will first explain this our invention as applied to the securing of the
breech block, and in doing so we will first explain the method shown in Figs. 1,
2, 2, 3 and 4.
10, is the action body, the general construction and arrangement of which is
now well known. 11 is a portion of the gun stock, and 12, the one end of the
barrel. Upon the inside of the sides of the action body are studs 13, which are
part circular in shape, that is, having flats 14, as seen in Fig. 2. These studs
form the trunnions or pivots upon which the breech block 15, shall oscillate.
In the said block 15, hole 16 is made to correspond with and in which the

page_text: studs 13, shall movably fit. Each end of this hole is made slotwise at 17, so
that in one certain position the block may be passed over the narrow parts 14
of the studs, 13. Having been thus passed on to the studs, the block will be
free to oscillate to the required extent in use without fear of displacement, but
can be removed at any time by being again turned sufficiently far for the slot 17,
to coincide with the flats 14, upon the studs 13.
We will now proceed to explain the method of securing the trigger guard
body 18, and here we would explain that hereinafter when speaking of the
trigger guard body we thereby refer also to the various parts carried thereon,
such as the tumbler 19, extracter 20, and lever 21, and trigger guard 22. These
parts are connected to the body 18, independently of the action body 10.
Referring now to Figs. 1, 5 and 6, the extractor 20, is carried upon a joint
pin 23, whose length terminates at the outsides of the trigger guard body 18.
At the fore end one or more projections 24, are made to enter corresponding
holes or recesses 25, in the fore part of the action body as seen in Fig. 1. Thus
it will be readily seen that by first passing the projection 24, into the recesses 25,
the rear part of the body 18, may be pushed upwards into position until the
pin 26, may be screwed into its place as seen in Fig. 1.
By these means it will be readily seen that by removal of the one pin 26, the
trigger guard body with its several parts, and also the breech block may be
removed or stripped without fear of losing the said parts, and of course may be
replaced in the same expeditious manner.
Having now particularly described and ascertained the nature of this our
invention, and in what manner the same is to be performed, we declare that what
we claim is :-
1. In Martini breech loading fire arms, the securing of the block 15, to the
action body by means of studs 13, having flats 14, in combination with the hole
in 15, having slots 17, all substantially as set forth and shown.
2. In Martini breech loading fire arms securing the trigger guard body 18,
to the action body 10, by means of the projection 24, taking into holes 25, in
combination with pin 26, passing through action body and trigger guard body,
all substantially as set forth and shown.
3. The general combination of the several modes of fastenings shown and
described, which together form means for securing the breech block and trigger
guard in the action body 10.
