page_text: I, PETER JENSEN Fel. Inst. P.A. of 33 Chancery Lane in the County of
Middlesex do hereby declare the nature of this invention, a communication to me
from abroad by Heinrich Wolfien of Stavenhagen Mecklenburgh Germany Manu-
facturer and in what manner the same is to be performed to be particularly.
described and ascertained in and by the following statement:-
The main object of this construction of fire-arm is to take away the greater part
of the work which heretofore in other systems of fire arms has been done wholly by
the right hand viz:-the opening and closing of the breech, the insertion of the
cartridge and the pulling of the trigger, and to give the work to the left hand
which has heretofore had nothing to do in the manipulation of the mechanism.
For this purpose a handle or pull is arranged under the barrel of the gun and so
connected with the breech that by simply pushing this handle forward or backward
by the left hand the opening or closing of the breech is effected, the ejection of the
empty cartridge case in the opening of the breech and the setting or drawing back
of the bolt, or striker in the closing of the breech being effected automatically.
A gun thus constructed may be made for ordinary single firing, or with any
repeating appliance as a magazine gun.
On the 'accompanying drawings this new gun is shewn in connection with a
repeating appliance Figures 1 and 2 being respectively vertical longitudinal sections
through the gun with the working parts in the open and closed position respec-.
tively and the other Figures shewing details.
The breech closing appliance of this new gun consists of the chamber or block B
which can slide in the breech socket A and in its interior contains the bolt or
striker C with nut c¹ and helical spring c.
The block B is in Figure 1 shown in its back position. Its rear end is
cut off slanting. D and D¹ are two wedges forming stops in its forward posi-
tion as shewn in Figure 2. These wedges are acted on by the spiral springs E E¹
and are by them pushed up through a slot ao in the breech socket A, shewn more
clearly in plan and cross section in Figure 17. The form of these wedges is
shewn in end view and side view and plan in Figures 18 and 19.
Each wedge
has an upper slot for the striker, and at its lower end d and d¹ respectively.

wedge D¹ is when the trigger F is pulled back drawn down also viz:-by means
of a peg d' on the lower end of the wedge D which peg d' works in the slot & in
the wedge D¹, and the latter may remain in this position in case the block B should
not happen to be pushed quite forward, because the length of the slot d' is such
that the wedge D with its peg d may freely follow the action of the spring E and
be thrown quite high up.
If the trigger F is pressed back the wedges D and D' will be drawn out of the
slot in the breech socket A Figure 1, and the block B may now be pushed back.
The slanting front wedge D¹ is in its up and down motion guided against the
plate a¹ shown respectively in three views Figure 21, which plate however may be
omitted.
The double wedge effects absolute certainty of closure so that the block cannot
possibly fly out. For should it happen that the slanting wedge D¹ be not thrown
quite high up whereby the block when it was not taken properly hold of by the
wedge D, might slip off for instance if the left hand when firing very quickly does
not push hard enough, or if the cartridge should jamb a little and therefore is not
pushed in far enough or if the block when shooting very quickly should expand a
little by heat.-then the block would fly up against the freely projected straight
wedge D; this latter hence forms absolute security against the block flying out.
The application of a special safety appliance for preventing the cartridge from
dropping out after insertion is not required. When the gun is ready for firing but
is not yet to be fired off the two wedges D D¹ are pulled down by means of the

quence of the spring c being in position for action the block will jump back
10 or 13 (to inch) whereby the power of the spring c is spent. The block
will by reason of this manipulation not go back any further because the
springs E E¹ press the wedges D D¹ against the block and thus hold it fast.
When the gun is to be put "full cock" or ready for firing the handle or pull L
Figures 1 and 2 needs only to be pushed forward about 10 or 13mm (to

inch)
The block B carries at the end or head the usual cartridge extractor (not shewn
in the drawing) and has a lower longitudinal groove b into which passes the
trigger peg G¹. When now the block B is moved forward the nose c¹ of the striker
nut comes against the trigger peg G¹ and this latter thereby holds the striker C
fast. If the block B is pushed further forward then the spring c will be set for
action the trigger peg G passes into the socket A and may also pass through a
strengthening plate g Figures 1 and 20. The trigger peg G₁ has as shown in
Figure 3 a lower prolongation through which the trigger G passes.
The spiral spring H holds the trigger peg G¹ up so that the trigger G after having
been drawn back by the index finger will at once be thrown forward again and the
peg G fly up again. The spiral springs E E¹ have a similar action; when the
wedges D D are pulled down by means of the trigger F they will when the
trigger F is released fly upwards unless the block B prevents this action.
On the head of the block B the screw k and the safety peg k² serve to fix the
rod K which extends forwards under the barrel and terminates in the handle or
pull L.
The lump k on the rod K is guided in a groove in the lower part of the
socket A. The rod K is also guided by the bracket S which is brazed on to the
bottom of the barrel. If now the wedges D D₁ are pulled back by means of
the trigger F Figure 1 then the block B may by means of the pull L which is
taken hold of by the left hand be easily pushed forwards and backwards.
If no account is taken of the magazine or repeating arrangement shewn in the
drawing and the screw O which passes into a short groove b¹ in the block B is
screwed back and out of the groove b¹ then the gun is used without the magazine
in the following manner beginning with the position of the parts shewn in Figure 2.

page_text: The trigger F is pulled back with the right band index finger and the pull L
pulled back with the left hand. The working parts will then assume the position
shown in Figure 1. The trigger F is now let go a cartridge is with the right band
put into the barrel and the pull L with the left hand pushed forward the gun is
now ready for firing. By pulling the trigger G Figure 2 the striker C is released
and thrown against the cap of the cartridge.
For extracting loading and firing of the gun there are altogether five actions
required including the insertion of the cartridge viz:
1. Pulling back the trigger for the double wedge D D¹ by the index finger of
the right hand.
2. Pulling back the pull L or opening the breach with the left hand.
3. Inserting the cartridge with the right hand.
4. Pushing the pull L forward thus closing the breech with the left hand.
5. Pulling the trigger G with the index finger of the right hand.
The throwing out of the spent cartridge case from the breech is done by a special
extractor which springs forward through the pulling back of the pull L and the
opening of the breech and which after the ejection is drawn back by means of the rod K
connected to the pull L. This cartridge extractor is shown specially in Figures 4 to 7.
Figure 4 being a vertical cross section through the line y y of Figure 1, Figure 5 a
cross section on zz and Figures 6 and 7 side views of Figure 4 and respectively in
the direction of the arrow 1 and the arrow 2. The extractor itself consists of the
spring M with peg m which goes through the socket A. The spring M is by means
of a wedge N with plate P which can slide on the socket A when the chamber B
is pushed back raised so far as to pull the peg m out of the socket A. The wedge N
is moved by the slot q q¹ Figure 6 into which enters the nose n on the plate P.
When the rod K is moved by the pull L the wedge N will likewise slide forwards
and backwards. The movement of the wedge N is limited by the screw pegs p. p¹
fixed in the socket A and working in length slots in the plate P. In the opening
of the gun or pushing back of the block B the cartridge case is thrown out auto-
matically, because the spring M (the nose m of which rests against the block when
the gun is closed) becomes free and throws out empty case.
Immediately thereupon after the spring M has acted the wedge N is pushed so
far under the spring M that this latter assumes the position shown in dotted lines
in Figure 7. In the closing of the gun or forward motion of the block B the latter
will close the hole for the peg m in the socket A before the wedge N is drawn out
under the spring M. When the block has been pushed so far forward, the wedge N
will be drawn out under the spring M and the spring M remains in tension until
the block again in the opening operation is pushed so far back that the hole for the
peg m becomes free whereby the spring again comes into action and flings out the
empty cartridge case.
All the parts belonging to the action are only fixed on the socket A and the
barrel and only laid into the stocks; no screw driver is therefore needed for
separating the stock from the barrel and action. For this purpose the socket
terminates in a dovetail like prolongation which has a set off at a³ which when the
barrel is put in is placed under a plate R fixed on the stock. The barrel is then
put in until the bracket S under the barrel comes against the spring bolt T; the
latter with its nose is then pushed back and the barrel pressed firmly into the
stock; the bolt T impelled by a helical spring slips into the hole provided for it in
the bracket S, whereby the barrel is fixed in the stock. The barrel is taken out of
the stock by first pushing the bolt T so far back that its head comes out of the
hole in the bracket S whereupon the barrel with the whole of the action can be
taken out of the stock. But both in the insertion and the removal of the barrel it
must be observed that the cartridge ejecting spring M is in the spent condition as
shown in full lines in Figure 7 because otherwise the spring M would cause
jambing in the insertion of the barrel, that is to say that the block must be put
back about half its stroke when the spring M is to have that position.

page_text: The gun may be combined with magazine or repeating appliances of very
different constructions; the one shown here consists of a magazine tube U Figures 1
and 2 placed on the top of the barrel and filled from the barrel opening end with
cartridges which are conveyed into the breech by means of a pusher V set in motion
by the block B. The magazine U is as well as the barrel provided with sights and
made removable from the barrel in the same way as the barrel is removable from
the stock,
Figures 8, 9 and 10 are plan side view and plan of underside of the rear end of
the magazine U and Figures 11 and 12 are side view and front view of the front
end of same Figures 13, 14 and 15 are cross sections on lines 11, 22 and 33 of
Figure 9, and Figure 16 back end view. The rear end of the magazine has a
projection u provided with dovetail notch and fitting in under the correspondingly
formed plate a on the socket A, Figures 1 and 22.
The other end of the magazine
carries a ring u¹ Figure 12 which can be pushed. like a cover over the mouth of
the barrel and there be jambed fast by mean of the catch u².
To remove the magazine the catch u' is raised so that its nose u³ comes out of
the wall of the barrel and the magazine may then be pulled forward and off the
barrel.
The cartridge feeder consists of a rod V which can slide in a longitudinal slot in
the tube U projecting partly beyond the same see Figure 10 and being guided in
staples u Figures 11 and 13. It carries one or two U-shaped plates v¹ which slide
on the outside of the tube U and serve to steady and guide the rod V. The latter
is at distances equal to the length of a cartridge provided with springs ³ the free
ends of which project into the magazine tube U Figure 10. The springs v² act in
conjunction with the springs us which are placed at similar distances on the tube U
and also have their free ends projecting into it.
For filling the magazine the rod V takes the position shown in Figures 2 and
11 and the ends of the springs v² and u stand opposite each other: see Figure 10.
One cartridge after the other is then put in from the front until the magazine is
charged; the cartridges are then held by the springs vand u³. By moving the
rod or bar V in the direction of the arrow Figure 10 the cartridge will be carried
along by the spring v³ on the bar, and the spring us will be pushed back by the
rim of the next following cartridge. The spring u however comes against the rim
of the latter and holds that cartridge fast when the motion of the bar V stops.
The hindmost cartridge will when the bar V is pulled back (when the breech is
open) drop through the correspondingly formed hole in the tube U Figure 10 and
into the breech socket A Figure 1 and will when the breech is closed by the
block B be pushed into its place in the barrel see Figure 2. In the back motion of
the bar V the springs us hold the cartridge while the springs v³ yield.
The back end of the bar V is formed with a set off part-see Figure 10, which is
guided in the closed end of the tube U; it is moved backward and forward from
the block B by the screw peg O which is screwed into the bar V and is guided in a
slot in the tube U its lower end projecting into a slot b in the block B.
The manipulation of the repeating gun with the magazine is the same as above
described only the cartridge has not to be inserted and the right hand has no other
work than to pass the index finger from one trigger to the other as with a double
barrelled gun.
If the magazine is to remain on the gun while the gun is nevertheless to be used
as a single loader it is only necessary to screw back the screw peg O so far that.its
lower end comes out of the groove. 6 in the block B. Any other suitable carrier
contrivance may be used instead of the screw peg O.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that, what
I claim as the invention communicated to me is
First. A gun in which the breech block is so connected with a rod provided with
handle that the breech is opened and closed by the left hand of the operator...

page_text: Second. The two wedges or keys D D₁ placed behind one another the foremost
one D being slanting and the hindmost one straight, which keys are moved by a
trigger F and by means of springs E and E¹ are automatically and independently
thrown up and serve to hold the block B in its foremost closing position..
Third. The block B in combination with a striker C and striker nut c¹, and a
trigger peg G which tends to spring upwards, rests against the striker nut, holds
back the striker when the block is moved and causes the striker spring to be set
for action.
Fourth. A cartridge case ejector consisting of a spring M with peg m projecting
into the block, and of a wedge N which can slide along the breech socket, the said
parts being so arranged that the ejector is self-actingly put in motion by the
motion of the block.
Fifth. The fixing of the action only to the barrel and to the breach socket and
the fixing of the stock to the barrel by means of a nose a² on the latter and an
angular bracket S on the barrel in such manner that by releasing a spring bolt T
arranged in the stock and catching into the bracket S the barrel and the action
may be separated from the stock.
Sixth. Arranging the magazine tube with front and rear sight centrally above
and on the barrel.
Seventh. Fixing the magazine tube U over the barrel in such manner that a
set off at the rear end of the tube catches under a plate a on the breech socket,
and a ring u¹ fixed at the mouth of tube takes round the mouth of the barrel, the
fixing being such that by releasing a catch u³ ³ in the ring the magazine may be
taken off the barrel.
Eighth. The springs us which reach into the magazine tube and are fixed at
distances apart equal to the length of a cartridge in combination with a bar V that
can slide in a slot in the magazine tube and that is provided with springs v³ at
distances apart equal to the length of a cartridge and reaching into the interior of..
the tube so that when the bar V is pushed forward catching behind the rim of the
cartridge the latter is moved forward the length of a cartridge, while when the
bar V is pushed back the cartridges are held by the springs u³.
Ninth. The construction of gun described and shown.
