Improvements in Small-arms and Machine Guns.
I, GEORG RASCHEIN, of Malix, in the Republic of Switzerland, Engineer, do
bereby declare the nature of this invention to be as follows:-
This invention relates to a fire-arm in which when fired off the recoil or
backward pressure of the gas on the cap and pin is utilised for working the lock
apparatus.
The rear end of the pin which together with the cap is driven back by the
pressure of the gas when the gun is discharged is in contact with a sliding piece
movable on its axis which serves to charge or load the weapon and is therefore
called the loader. The pin is driven back by the recoil and carries the loader with
it and the latter at the end of its backward course comes into contact with a spring
stop lever or catch and is held by it. The backward movement of the loader
brings two sets of spiral springs into tension at opposite sides one set of which
serves to drive the lock cylinder back and the other to drive the loader forward.
When the trigger is released, respectively after the cessation of the gas pressure on
the pin one set of springs is set free so that the lock cylinder unfastened by means
of levers and notched plate can fly back. When the lock cylinder flies back it or
a sliding piece in connection with it liberates the loader which now being driven
forward by its springs pushes forward the lock cylinder in front of which a fresh
cartridge has been deposited so that the gun is again ready for discharging. Both
in fastening and unfastening the lock cylinder on its block the turning is accomplished
by means of a radial arm or stud on the rear end of the cylinder moving in a radial
slot so that at the proper moment projections forming a lock on the nozzle of the
cylinder are caused to pass behind or are released from a shoulder or flange on the
block.
Passing from this general description of the fire-arm in one construction the pia
may be made with a cylindrical conical head attached to the lock cylinder. The
loader consists of a cross piece with two tubes attached thereto and has a central
opening with a conical face for the reception of the conical head of the pin. Into
each of the tubes which lie in lateral slots in the body of the gun a spiral spring is
fitted one end of which rests against the ends of the tubes and the other against
projecting studs. The studs are fastened in a block or cross-piece which can be
taken away by lifting up a pin. A bent and pivoted lever is fixed on a pin one arm
of which is moveable downwards and can be pressed upwards by a spring. This
arm has a notch in which the cross piece of the loader catches so that the latter
cannot spring forward until it is released by the notch. When the loader is moved
back the springs in the tubes attached to the cross piece are compressed.
Before the loader an apparatus for rotating the lock cylinder is arranged cou-
sisting of a sliding plate and a triple bored cross-piece which is guided by bars.
Through the centre hole of this cross piece passes the head of the pin and the tubes
of the loading apparatus pass through the other holes. The ends of two spiral
springs which encircle and are connected with the tubes rest against the cross piece
of the cylinder rotating apparatus whilst the other ends rest against the bottom of
these tubes. These springs which are also compressed when the loader is moved
back tend to drive back the lock cylinder rotating apparatus.

page_text: As long, as the finger is pressed upon or holds the trigger the lock cylinder
rotating apparatus cannot follow the pressure of the springs as the upper arm of
the bent and pivoted lever places itself before the cross piece of same and stops it.
This arm has a slot in the centre and on the underneath side an inclined surface
with which projections on the trigger plate arms engage. The trigger plate is
penetrated by the trigger and on the latter being pressed back is drawn back so
that the said projections come into contact with the inclined surface and raise the
arm of the bent lever. When the trigger is released a spring moves it again into
its normal position. At the same time the trigger plate is again pushed forward so
that the arm of the bent lever loses its points of support on the trigger plate arms.
Through the operation of a spring this lever is turned on its pivot causing the arm
to fall and leaving the cross piece of lock cylinder rotating apparatus free. The
lock cylinder rotating apparatus then yielding to the pressure of the springs moves
or springs back and by the action of a pin in a groove therein releases the cylinder
and draws it back with it, the cross piece engages with and presses down the stop
arm and releases the loader which responding to the pressure of its springs and
pushing before it the cylinder rotating piece with the cylinder springs forward and
pushes a fresh cartridge into the barrel. In order to unfasten the lock cylinder
when the rotating piece moves back and fasten same when it moves forward the
back end of the cylinder is fitted with a projecting pin or stud. For the same
purpose the rotating piece has on the under side of the sliding plate an oblique
groove into which the thin part of the said pin enters and the body of the gun has
an inclined surface against which comes the thick part of the said stud. When the
rotating piece commences to move back the pin or stud by the co-operation of the
oblique groove and the inclined plane is turned to the right and at the same time is
to some extent pushed back so that projections on the other end of the cylinder
move clear of flanges on the body of the gun and the cylinder is unfastened. In
this position the cylinder is enabled to follow the rotating piece in its backward
course. When the rotating piece has finished moving forward the oblique groove
and the inclined plaue act in the contrary way and turn the cylinder to the left and
during the latter part of its passage the projections again engage with the flanges.
By means of a lug the loader with the cylinder can be pushed back by the hand for
the purpose of single loading &c. Care must be taken that the pin which is pushed
forward by the loader does not advance to such an extent as to cause an uninten-
tional ignition of the cartridge. For this purpose a hammer is fitted with a bent
lever arm which when the hammer is on cock stops the head of the pin before the
point of the latter reaches the cartridge. As soon however as the hammer is
released the arm leaves the head so that the pin can be pushed forward by the
hammer. In order to effect the re-cocking of the hammer by the backward
movement of the loader even whilst the trigger is being pressed a pivoted stop arm
is adjusted on the axis of the trigger, which arm can enter a recess in the trigger and
can be pressed forward by a spring. This stop arm has a notch in which a
projection on the hammer engages. By pressing on the trigger the trigger plate is
drawn back which causes a projection thereon to move back the stop arm.
the trigger plate moves back sufficiently the notch on the stop arm releases the
hammer and the arm leaves the projection on the trigger plate. A spring moves
the arm forward so that the hammer when cocked is caught again in the notch
thereon. When the trigger is released a spring drives the trigger and the trigger
plate forward and the latter sinks a little when the projection slides under the stop
arm. A spring lifts the plate again as soon as the projection thereon has passed
by under the stop arm the connection between the projection and the arm is thus
restored.
The way in which the fire arm works is as follows:-
When
As has just been described by pressing on the trigger the hammer is released
so that by means of a spring it is driven forward against and propels forward
the pin. At the same time a lever arm is lifted by projections so that it lies
before the side of the lock cylinder rotating apparatus. The gases arising

page_text: from the ignition of the powder drive the projectile forward and the cap acting
on the pin drives it backwards. The receding pin takes the loader with it and
leaves it caught in a notch of an arm. When the loader moves back spiral
springs are compressed and the hammer is cocked being held by a notch on a
stop arm. As soon as the trigger is released it goes back into its normal position
when a projection of a plate which has been pushed forward again comes into
contact with the arm. The lever arm no longer supported by the projections
falls by the action of a spring so that the lock cylinder rotating apparatus is
released and springs back by the action of the springs. When this rotating
piece begins to run back the lock cylinder by the help of an oblique groove
and inclined plane is turned to the right drawn back and unfastened so that it
can follow the rotating piece. The extracting hook as it is well known now
draws back the remainder of the fired off cartridge which is then thrown out
by the usual well known appliance. When the cylinder moves back its projec-
tions or lugs come into contact with the arms of a pivoted tumbler whereby its
foremost part is brought before the cylinder bore and the cap which has been
pushed off by the pin is conducted below escaping through an opening in the plate.
A stud stops the backward movement of the pin.
At the end of the backward course of the rotating piece its cross piece
presses down the arm of a lever whereby the loader is liberated and responding
to the pressure of its springs darts forward. The rotating piece and the cylinder
before which a fresh cartridge out of the magazine has been deposited are also
driven forward so that the arm is again ready for firing. By means of an
oblique groove and an inclined plane the cylinder is turned to the left and
pushed into the position for fastening.
Whilst preserving the essential principle of the firearm the adjustment and
operation of the loader cylinder locking apparatus and the springs working in
opposite directions may be varied. The loading piece may have the shape of a
socket encircling concentrically the lock cylinder which can be moved along its
axis and can be pressed forward by the action of a spring at its back end.
Between the front end of the socket and the cylinder head a spring is adjusted
which effects the unbolting and the back action of the cylinder. The cylinder
rotating apparatus is in this case brought on to the loading socket and possesses
an inclined plane. When the pin is driven back by the powder gases it draws
the socket back which compresses the springs. The foremost end catches in a
notch of the stop lever whereby the socket is held in its backward position.
When the socket goes back the cylinder rotating apparatus slides over a shoulder
of the cylinder head and an inclined plane comes close behind this shoulder.
After the effect of the pressure of the gas on the pin has ceased the compressed
spring drives the cylinder back. A shoulder slides along an inclined plane to
the left through which movement the cylinder receives a turn in the same
direction so that the bolt projections are released and allow the cylinder to
move back. To render this back action possible the shoulder leaves the inclined
plane when it has reached its left end and slides back with the cylinder under
the rotating piece. At the end of the backward course of the cylinder it has
a projection which lifts the arm of the lever and releases the socket from the
notch so that the compressed spring can drive the socket and the cylinder
forward. An inclined surface on the back end of the socket causes the cylinder
at the end of its backward course to turn to the right aud fastens it thus again.
The springs which by means of an appropriate arrangement can be drawn back
a short distance and then suddenly let go serve here at the same time as springs for
the pin. Care must be taken that when the pin is driven forward by the release
of the socket no ignition of the cartridge takes place.
The fire-arm may be used both as an ordinary repeating rifle and as a so-called
machine arm. In this arrangement the hammer is pivoted to an extension of the
moveable loading piece which is worked by a spring which is placed against a fixed
projecting pin. In consequence of the backward passage of the pin owing to the

page_text: gas pressure the loading piece is driven back and brought behind a stop arm.
When the loader is driven back the cocking of the hammer is accomplished either
through its own inertia or through its lower cam coming into contact with a
check. At the same time a projection catches in a notch of the trigger lever.
The spring in a state of tension would lower the arm of the lever but cannot do so
as long as the finger keeps the trigger back because a part of the lever is kept up
by the back sloping end of the trigger plate. When the trigger is released the
spring can lower the lever arm whereby the trigger is thrust forward and the
cylinder turning apparatus is set free. The latter is driven back by a spring and
releases the loader whereupon the other parts return to their positions in the way
no repeatedly described.
To utilize the same weapon as an automatic machine fire-arm the slide fitted in
the trigger is pushed forward so that the back end of the trigger connected with
the springs is released and by means of the pressure exercised by the spring and by
a part of the lever will immediately give way downwards. The liberation of the
rotating part and the closing movements in this case follow immediately after the
recoil of the pin with the loading piece. As the trigger after first being drawn by
the finger remains in its backward position the hammer relaxes automatically every
time the loader moves forward. To stop the pin in its forward course there is
a book which is lifted out by the hammer when released so that the pin is
liberated.

Improvements in Small-arms and Machine Guns.
I, GEORG RASCHEIN, of Malix, in the Republic of Switzerland, Engineer, 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 a fire-arm in which when fired or discharged the recoil
or backward pressure of the gas on the cap and pin is utilised for working the lock
apparatus.
In the accompanying drawings Figures 1 and 2 represent one arrangement of the
self acting fire-arm being respectively a vertical section and a plan while Figures 6
and 7 are vertical sections representing two modifications of the arrangement.
Figures 3 to 5 show certain parts in detail which will be more particularly dealt
with subsequently.
The rear end of the pin A which together with the cap a is driven back by the
pressure of the gas when the gun is discharged is in contact with a sliding piece
movable along its axis which serves to charge or load the weapon and is therefore
called the loader. The pin is driven back by the recoil and carries the loader with
it and the latter at the end of its backward course comes into contact with a spring
stop lever or catch and is held by it. The backward movement of the loader
brings two sets of spiral springs into tension at opposite sides one set of which
serves to drive the lock cylinder back and the other to drive the loader forward.
When the trigger is released, after the cessation of the gas pressure on the pin one
set of springs is set free so that the lock cylinder unfastened by means of levers
and notched plate can fly back. When the lock cylinder flies back it or a sliding
piece in connection with it liberates the loader which now being driven forward by
its springs pushes forward the lock cylinder in front of which a fresh cartridge
has been deposited so that the gun is again ready for discharging. Both in

page_text: fastening and unfastening the lock cylinder the turning is accomplished by means
of a radial arm or stud on the rear end of the cylinder moving in an oblique slot
so that at the proper moment projections forming a lock on the nozzle of the
eylinder are caused to pass behind or are released from a shoulder or flange on the
block.
Passing from this general description of the fire-arm to the examples shown in
the drawings which however do not exhaust the possible arrangements, A in.
Figures 1 and 2 shows the pin with a cylindrical conical head attached to the lock
cylinder B. The loader C consists of the cross piece c with the two tubes e and *.
attached thereto one at either side of a central opening e' with a conical face c' for
the reception of the conical head a of the pin A. The tubes c c lie in the slots
or grooves d placed at each side of the body D of the gun and in each of the tubes
a spiral spring E is fitted one end of which rests against the end of the tubes c¹
or and the other against the end of the stud F or F'. The studs F F' arc
fastened to the block or cross piece d' which can be removed on withdrawing the
pin d. G is a bent lever pivoted on the fixed pin g the arm g¹ of which is capable
of being moved downwards and is held or pressed up by the spring 9. The
arm g' has a notch 9³ in which the cross piece c of the loader C catches (see Fig. 1).
so that the latter cannot spring forward until it is released from the notch g³.
When the loader C is moved back the springs E in the tubes c¹ and c³ attached to
the cross piece e are compressed. (See Fig. 2.)
Fig. 1 shows the fire-arm just at the moment it has been fired but before any
further movement has taken place. Fig. 2 on the other hand represents the
position immediately following in which the pin A has been driven back and the
cross piece c of the loader C has been caught in the notch g' of the arm 9'. In
front of the loader C an apparatus H for rotating the lock cylinder B is arranged
consisting of a sliding plate and a triple bored cross piece h¹ which is guided by
the bars d (represented in Fig. 3 as seen from below). Through the centre
hole of the cross piece passes the head a of the pin A and the tubes c² c* of.
the loading apparatus pass through the holes. The ends of the spiral
springs JJ which encircle and are connected with the tubes crest against
the cross piece whilst the other ends rest against the bottom of these tubes
(see Fig. 2). The springs J J which are also compressed when the loader is
moved back tend to drive back the lock cylinder rotating apparatus H.
As long as the finger is pressed upon or holds the trigger K the piece H cannot
follow the pressure of the springs JJ' as the upper arm of the bent pivoted lever G
is raised in front of the cross piece h' and stops it. The arm g' has a slot in the
centre and on the underneath side an inclined surface with which the
projections on the trigger plate arms ¹ engage. The trigger K passes through
aslot in the trigger plate and on the trigger being pressed back the plate k is
also drawn back so that the projections come into contact with the inclined
surface g³ and raise the arm g' of the bent lever G. When the trigger is released
the spring moves it again into its normal position. At the same time the trigger
plate is again pushed forward so that the arm g* loses its points of support k².
Through the operation of the spring g the lever Ğ is turned on its pivot causing
the arm g to fall and leaving the cross piece h' free. The piece H then yielding
to the pressure of the springs J J' moves or springs back and by the action of the
pin in the groove therein releases the lock cylinder B and draws it back with
it, the cross piece ¹ engages with and presses down the stop arm gl and releases
the loader C which responding to the pressure of its springs E and pushing before
it the piece H with the cylinder B springs forward and pushes a fresh cartridge
into the barrel.
In order to unfasten the lock cylinder B when the piece H moves back and
fasten same when it moves forward the back end of the cylinder B is fitted with a
projecting pin or stud 6 b¹ Figs. 1, 2, and 4. For the same purpose the piece H bas
on the underside of the sliding plate h an oblique groove / Figs. 1, 2, and 3 into
which the thin part b of the said pin enters and the body of the gun has an inclined

page_text: •
surface d' against which comes the thick part 1 of the said stud. When the
piece H commences to move back the pin or stud bb by the co-operation of the
oblique groove 1 and the inclined plane d' is turned to the right and at the same
time is to some extent pushed back so that the projections on the other end of
the cylinder are turned clear of the flanges d³ on the body of the gun (Fig. 1, and
Fig. 5 section on a Fig. 1) and the cylinder is released. In this position the
cylinder is enabled to follow the piece H in its backward_course. When the
piece H has finished moving forward the oblique groove h and the inclined
plane act in the contrary way and turn the cylinder to the left and during the
latter part of its passage the projections again engage with the flanges b. By
means of the lug the loader C with the cylinder B can be pushed back by hand
for the purpose of single loading etcetera. Care must be taken that the pin A
which is pushed forward by the loader C does not advance to such an extent as to
cause an unintentional ignition of the cartridge. For this purpose the hammer L
is fitted with a bent lever arm which when the hammer is on cock (the position
shown by dotted lines in Fig. 1) stops the head a of the pin A before the point of
the latter reaches the cartridge. As soon however as the hammer is released the
arm leaves the head a so that the pin can be pushed forward by the hammer. In
order to effect the re-cocking of the hammer by the backward movement of the
loader C even whilst the trigger is being pressed a pivoted stop arm M is adjusted
on the pivot g of the trigger K. This arm M is placed in a recess k* in the trigger
and is pressed forward by a spring m and has a notch m' in which the projection /
of the hammer L engages. By pressing back the trigger K the trigger plate k is
drawn back which causes the projection thereon to move back the stop arm M.
When the trigger plate k moves back sufficiently the notch m' on the stop arm
releases the hammer L and the arm M leaves the projection on the trigger
plate. The spring m moves the arm M forward so that the hammer when cocked
is caught again in the notch m'. When the trigger is released the spring drives
the trigger K and the trigger plate k forward and the latter sinks a little when the
projection slides under the arm M. The spring 4 lifts the plate k again as soon
as has passed by under the stop arm M the connection between the projection **
and the arm M is thus restored.
The way in which the fire-arm works is as follows:-
As herein described by pressing on the trigger K the hammer L is released so
that by means of the spring it is driven forward against and propels forward the
pin A.
At the same time the lever arm 9 is lifted by the projections * so that it
fies in front of the side of the lock cylinder rotating apparatus H. The gases
arising from the ignition of the powder drive the projectile forward and the cap
acting on the pin A drives it backwards. The receding pin A takes the loader C
with it and leaves it caught in the notch g³ of the arm g'. When the loader C
moves back the spiral springs E J J' are compressed and the hammer L is cocked
being held by the notch m¹ of the stop arm M. As soon as the trigger K. is
released it returns to its normal position when the projection of the plate k
which has been pushed forward again comes into contact with the arm M. The
lever arm 9 no longer supported by the projections falls by the action of the
spring so that the lock cylinder rotating apparatus H is released and springs
back by the action of the springs J J'. When the piece H begins to travel back
the lock cylinder by the help of the oblique groove h6 and inclined plane dis
turned to the right drawn back and unfastened so that it can follow the piece H.
The extracting hook which is not shown in the drawings as it is well known now
draws back the remainder of the fired off cartridge which is then thrown out by the
usual well known appliance. When the cylinder B moves back its projections or
lugs 62 come into contact with the arms de of a pivoted tumbler lying under the
cylinder B whereby its foremost part is brought in front of the cylinder bore and
the cap which has been pushed off by the pin is conducted below escaping through
an opening O in the plate D'.
The stud№8 stone the heckword movement of the nin A

page_text: At the end of the backward course of the piece H its cross piece h¹ presses down
the arm of the lever g¹ whereby the loader C is liberated and responding to the
pressure of its springs E darts forward. The piece H and the cylinder before
which a fresh cartridge out of the magazine N has been deposited are also driven
forward so that the arm is again ready for firing. By means of the oblique
groove and the inclined plane d' the cylinder B is turned to the left and pushed
into the position for fastening.
Whilst preserving the essential principle of the fire-arm the adjustment and
operation of the loader cylinder locking apparatus and the springs working in
opposite directions may be varied and Fig. 6 shows the horizontal section of a
fire-arm with the spiral springs E and J adjusted behind each other. The loading
piece C has here the shape of a socket encircling concentrically the lock cylinder B
which can be moved along its axis and can be pressed forward by the action of the
spring E at its back end. Between the front end of the socket and the cylinder
head Bo the spring J is adjusted which effects the unbolting and the back action of
the cylinder B. The cylinder rotating apparatus H* is in this case brought on to
the loading socket C* and possesses an inclined plane h". When the pin is driven
back by the powder gases it draws the socket C* back which compresses the
springs E and J. The foremost end Cº catches in the notch g³ of the stop lever G*
whereby the socket is held in its backward position. When the socket C* goes
back the cylinder rotating apparatas H* slides over the shoulder 6* of the cylinder
head B° and the inclined plane /* comes close behind the shoulder 6*. After the
effect of the pressure of the gas on the pin has ceased the compressed spring J
drives the cylinder back. The shoulder * slides along the inclined plane h* to
the left through which movement the cylinder receives a turn in the same direction
so that the bolt projections are released and allow the cylinder to move back. To
render this back action possible the shoulder 6* leaves the inclined plane * when
it has reached its left end and slides back with the cylinder under the piece H*.
At the end of the backward course of the cylinder B its right projection & lifts
the arm of the lever G* and releases the socket C from the notch g' so that the
compressed spring E can drive the socket (and the cylinder B forward. An
inclined surface 6* on the back end of the socket C causes the cylinder B at the
end of its backward course to turn to the right and fastens it thus again. The
springs E and J which by means of an appropriate arrangement can be drawn
back a short distance and then suddenly let go serve here at the same time as
springs for the pin. Care must be taken that when the pin is driven forward by
the release of the socket C no ignition of the cartridge takes place.
Finally in Fig. 7 a representation is given of the invention showing the use of
the fire-arm both as an ordinary repeating rifle and as a so-called machine gun. In
this arrangement the hammer Lis pivoted to an extension of the movable
loading piece C** which is worked by the spring E which is placed against the
fixed projecting pin F**. In consequence of the backward passage of the pin A
owing to the gas pressure the loading piece C** is driven back and brought behind
the stop arm. When the loader is driven back the cocking of the hammer L**
is accomplished either through its own inertia or through its lower end coming
into contact with the check R. At the same time the projection ** catches in the
notch o of the trigger lever O. The spring E in a state of tension would lower
the arm g of the lever G** but cannot do so as long as the finger keeps the
trigger back because the part 9 of the lever is kept up by the back inclined end of
the trigger plate K**. When the trigger is released the spring E can lower the
lever arm whereby the trigger is thrust forward and the cylinder turning
apparatus His set free. The latter is driven back by the spring J and releases
the loader C** whereupon the parts C** H** A and B return to their positions
in the already described.
To utilize the same weapon as an automatic machine gun the slide P fitted in
the trigger plate K** is pushed forward so that the back end of the trigger plate
acting as a flat spring is released and by means of the pressure exercised by the

page_text: spring E and by the part 9 of the lever will immediately give way downwards.
The liberation of the part H** and the closing movements in this case follow
immediately after the recoil of the pin with the loading piece. As the trigger
after first being drawn by the finger remains in its backward position the hammer
relaxes automatically every time the loader C** moves forward. To stop the pin
in its forward course there is a hook Q which is lifted out by the hammer when
released so that the pin is liberated.
Having now particularly described and ascertained the nature of the said inveu-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. A self acting fire-arm having an immovable barrel and a pin A forced back
by the pressure of the gas constructed with an axially movable loading organ C
which engages with the back end of the pin and which in its backward movement
bends springs E J operating in opposite directions, one of which J unbolts and
pushes back the lock-cylinder B whilst the other E pushes forward the loader C
to load the gun afresh substantially as described.
2. In a self acting fire-arm such as described the loader C to which the back
pressure of the gas is transferred by means of the pin A consisting of two parallel
tubes cc closed at the bottom end and a conically bored cross piece c to which
tubes spiral springs E are fitted which at one end rest against the bottom of the
tubes cc and at the other end against the fixed projecting pins F F'.
3. In a self acting fire-arm such as described the apparatus H for unbolting the
lock cylinder B consisting of a plate h with catch and guiding groove acting
upon a radial cylindrical stud b and of a cross piece with holes at both sides and
in the centre in combination with springs placed between the cross piece A¹ and the
rings projecting over the tubes c³ ³ which springs are put in tension when the
loader moves back for the purpose of unbolting and drawing back the lock
cylinder releasing the checked loader and again bolting the cylinder at the end of
its forward course.
4. In a self acting fire-arm such as described a check lever G actuated by a
spring whose rear pivoted stop arm g¹ holds the loader when thrown back and
whose front arm 9 provided with an inclined surface 9 is intended to stop the
apparatus H in connection with the projections fitted to the arms ¹ of the
trigger plate which when the trigger is pressed press on the inclined surface g
and bring the arm g' into the check position."
5. In a self acting fire-arm such as described the hammer L in the form of a
bent lever with an arm / which when the hammer is cocked takes up such a position
that when the pin A moves forward it is stopped by this arm before the point of
the pin can reach the cartridge for the purpose of preventing a premature ignition
of the latter.
6. In a self acting fire-arm such as described the trigger arrangement consisting
of a horizontal movable trigger plate k with projections and arms k¹ penetrated
by the trigger K and pressed upwards by means of a spring and of the stop arm M
pivoted on the trigger axle g pressed forward by means of a spring and provided
with a catch m¹ so that the plate k when drawn back by the trigger can turn back
the stop arm and let it go after the release of the hammer from the rest m¹ thereby
ensuring the immediate cocking of the hammer after the discharge even while the
trigger is being pressed.
7. A self acting fire-arm having the several parts constructed and arranged in
combination substantially as described with reference to either of the figs. of the
drawings.
Dated this 16th day of January 1805
