A communication from PAUL BRUN-LATRIGE, of 7 Cours Tauriel, Saint Etienne,
in the Republic of France, Armourer.
I, ALFRED JULIUS BOULT of 323 High Holborn, in the County of Middlesex,
Chartered Patent Agent, do hereby declare the nature of this invention to be as
follows:-
This invention relates to the automatic and continuous loading and firing of a
small-arm such as a pistol or sporting military or other gun or rifle the operation
being limited only by the capacity of the magazine and being effected by means only
of the pressure of the finger upon the trigger.
To this end the barrel, to which the trigger is fixed, is made movable in the
direction of its axis and abuts against a fixed breech which contains the percussion
device. The action of the trigger is therefore threefold ;-
1. To move the barrel backwards by the finger pressure;
2. To keep the barrel in that position before the discharge and
3. To fire the shot as soon as the backward movement of the barrel is
completed.
By this backward movement, the barrel energises a spring, the whole being
enclosed in a sleeve fixed to the body of the piece or formed in one therewith.
When the finger ceases to press on the trigger the coiled spring forces the barrel
forward at the same time ejecting the spent cartridge-case.
The mechanism consists of 6 principal parts;
1. The body comprising an outer barrel or sleeve, the magazine and chamber
containing the percussion device;
2. The movable barrel carrying the trigger or finger ring or projection ;
3. The main spring;
4. The hammer or firing pin with its spring;
5. The magazine with its cartridge-elevator and
6. The distributor-ejector.
Whether it is a pistol, musket, carbine, rifle, sporting gun, or a walking-stick
gun, to which this mechanism is applied, the system is identical, except as regards
the length of barrel entering into the body of the piece, and the form of the
magazine, which may be either a tube or a movable loader.
The following description of the various parts relates to the application of the
system to a pistol.
I. THE BODY.
.1. A sleeve which is formed in one piece with the body, and which encloses the
barrel and a main helical spring. (For all fire-arms the sleeve may be made
separately and secured to the body of the piece by means of screws or otherwise.)
2. The breech into which slides longitudinally the rear or breech end of the
barrel, provided with a lateral orifice giving passage to the tooth of the distributor-
ejector. It is into this breech that the cartridges are pushed by the cartridge-
elevator from the magazine. This breech is provided at its rear with two vertical
grooves which serve for the extraction of the empty cartridge cases, and which are
prolonged downwards to the bottom of the magazine.

page_text: On that part of the distributor-ejector which corresponds with the aperture
formed on the right side of the body there is a tooth cut away, on the front side
presented to the barrel in the form of a cam or inclined plane. This tooth
serves to deliver in front of the barrel the cartridge issuing from the magazine,
and to maintain it in that position until the moment of firing. It clears the
barrel laterally when the latter makes its retrograde novement, takes its place
above the next following cartridge in the magazine, and, after firing effects the
ejection of the spent cartridge-case, on the barrel returning to its forward
position, when the said case is thrust out of the grooves in the breech-block
by the feed-motion of the cartridge-elevator.
A second tooth may be placed below the first in such manner as to entirely clasp
the cartridge next in succession, and to facilitate its movement.
It may

sporting guns, military fire arms, walking-stick guns, and other fire arms.
be also applied to fire-arms using cartridges with heavy powder-charges, and by
the addition either of a system of breech closing for cannon, or by a brake-device
it may be adapted to moderate or minimise their movement or recoil or of pressure
and strain in front at the moment of firing, when the explosive gas exerts its first
force on the projectile as well as on the cartridge case and breech; while utilising
that movement for the extraction or ejection of the spent cartridge cases.
Lf desired a safety-device may be employed in conjunction with the before
described mechanism:

Improvements in Breeen-roading
A communication from PAUL BRUN-LATRIGE, of 7 Cours Tauriel, Saint Etienne,
in the Republic of France, Armourer.
I, ALFRED JULIUS BOULT of 323 High Holborn in the County of Middlesex,,
Chartered Patent Agent,.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.:—
This invention relates to the automatic. and continuous loading and firing of a
small-arm such as a pistol or sporting; military or other gun or rifle the operation
being limited only by the capacity of the magazine and being effected by means
only of the pressure of the finger upon the trigger.
To this end the barrel to which the trigger is fixed, is made movable in the
direction of its axis and abuts against a fixed breech which contains the percussion
device. The action of the trigger is therefore threefold ;-
1. To move the barrel backwards by the finger pressure;
2. To keep the barrel in that position before the discharge, and
3. To fire the shot as soon as the backward' movement of the barrel is
completed.
•
By this backward movement, the barrel energises a spring coiled round its rear
end, which, together with the spring; is enclosed in a sleeve fixed to the body of
the piece or formed in one therewith. When the finger ceases to press on the
trigger the coiled spring forces the barrel forward, at the same time allowing the
spent cartridge case to be ejected.
The invention will be best understood by reference to the accompanying
drawings in which, as an example; it is shown applied to a' pistol.
.

page_text: In these drawings,
Figs. 1 and 2 are elevations of respectively opposite sides of the pistol.
Figs. 3 and 4 are elevations of the front and back ends respectively.
Figs. 5 and 6 are plans of the upper and undersides respectively.
Fig. 7 is a longitudinal central section showing a spent cartridge case being
ejected.
Fig. 8 is a side elevation of the movable barrel and the trigger integral
therewith.
Fig. 9 represents the firing-pin and its attachments in two elevations taken at
right angles to each other and
Fig. 10 represents the cartridge-elevator in side elevation and plan.
Like letters indicate like parts throughout the drawings.
The mechanism consists of six principal parts, vis. ;-
1. The body G, comprising the outer barrel or sleeve M; the magazine B, and
the chamber L containing the percussion device;
2. The movable barrel A, carrying the trigger or finger ring or projection D;
3. The main spring R.;.
4. The striker, hammer or firing-pin P with its operating spring E
5. The magazine B, with its cartridge elevator F; and
6. The distributor-ejector H.
...
Whether it is a pistol, a musket, a carbine, a rifle, a sporting gun, or a walking-
stick gun, to which this mechanism is applied, the system is identical, except as
regards the length of barrel and the form of the magazine employed, the latter of
which may be either in the form of a tube or other device permanently or
detachably secured to the fire-arm or of the construction shown in the drawings
and hereinafter described.
The following description of the various parts relates to the application of the
system to a pistol as illustrated in the accompanying drawings.
I. THE BODY G COMPRISES ;-
(1) The sleeve M which encloses the barrel A. and the helical spring R. The
sleeve M may be made integral with or independent of and secured by screws or
otherwise to the other parts of the body.
(2) The breech 6 in which slides longitudinally the rear or breech end a of the
barrel A, and the wall of which is provided with a lateral orifice for the passage
therethrough of the tooth d of the distributor ejector H. It is into this breech
that the cartridges c are pushed by the cartridge elevator F, from the magazine.
This breech is provided at its rear with two vertical grooves rr, which serve for
guiding the cartridges and empty cartridge cases, and which are continuations of
the grooves extending upwards from the hottom of the magazine.
(3) The aperture e through which the empty cartridge. cases are ejected..
(4) The chamber L in which is located the striker or firing-pin P and in whose
wall is forined a slot or groove to enable the firing pin to be cocked and released
from outside the chamber L as hereinafter described.

leeve M to an extent corresponding to the length (from back to front) of the
reech opening e, its backward movement ceasing when the rear end of the barrel
buts against the front end of the firing-pin chamber L or the face which
constitutes the rear end of the opening e. The barrel A carries the trigger, finger
ing or projection D. The enlarged part i of the barrel is provided with a screw.
or equivalent which as before mentioned passes through the sloth in the
leeve M and is adapted to impart a swing-motion to the distributor-ejector H,
nd also to act as a stop for limiting the forward movement of the barrel.

page_text: On that part of H which corresponds with the aperture there is provided the
before mentioned tooth d cut away on the front on that. side which is presented to
the barrel so as to constitute a cam. or inclined plane. This tooth d serves to
retain in proper position in front of the barrel A the uppermost of the cartridges
issuing from the magazine B and to maintain it in, that position until the moment
of firing; it is moved: laterally, out of the breech: by, the barrel when the rear. end.
of the latter in. making its retrograde movement, bears against the cami face of the
tooth, the uppermost of the cartridges. then being received in: the rear end of
the barrel Al and the tooth d being lowered by the operation of the pin on the
cam surface H'. After the weapon is fired and the barrel A is allowed to move
forward under the action of the spring R the tooth d re-enters the breech, and
passes beneath the spent cartridge case and by the pin acting on the cam
surface. H the tooth. d is raised and the cartridge case is thereby ejected from. the
breech and the next full. cartridge allowed to come opposite the breech end of the
barrel A under the action. of the elevator. F and spring, Q..
A.second, tooth may be placed below the tooth d-in-such manner. that the two-
teeth will clasp between them.the.cartridge, next.in. succession.
The sides of the breech.end of the barrel A. are cut. away so as to admit of the
cartridge rims remaining in engagement with the grooves until the ejection of the
empty cases from the breech.
The before described: apparatus is applicable. to pistols, muskets, carbines, rifles,
sporting guns, military fire-arms, walking-stick guns, and other fire-arms. It may
also be applied to fire-arms using cartridges with heavy powder-charges:
If desired a safety device may be employed in conjunction with the before
described mechanism..
Having now particularly described and' ascertained the nature of the said
invention as communicated to me by my foreign correspondent, and in what manner
the same is, to be performed, I declare that what I claim is ;-
1. In a fire arm. the combination of a longitudinally reciprocating barrel with a
sleeve surrounding it a trigger fixed to it and a spring acting on it substantially as
described;.
2. In a fire arm the making ready or energising, and releasing of a tumbler
