PROVISIONAL SPECIFICATION.
Improvements in Air-guns.
I, OSCAR WILL, of Zella St. Blasii, Germany, Weapon-manufacturer, do hereby
declare the nature of this invention to be as follows:-
In an air-gun according to this invention the tilting or turning down of the
barrel causes the air-pump piston, which is completely enclosed in a separate
cylindrical casing, to be moved backwards and the firing-spring thereby compressed
or cocked, so that the piston will be shot forward after the liberation of the
firing-pin connected therewith.
An air-gun according to this invention is represented in longitudinal section in
Figs. 1 and 2 of the accompanying drawings,
Fig. 1 showing the piston uncocked that is to say in the position it assumes after
a shot has been fired; and
Fig. 2 showing the barrel turned down and the piston cocked.
Fig. 3 shows a cross section through the air-pump piston.
The barrel a is pivoted at 6 and is provided with an under-projection c to which
an arm d is connected. The arm d is at its rear end extended upwardly and
broadened and passes into the lock-box g' which latter contains within it a separate
cylindrical casing f, in which the piston 9 can be moved longitudinally. The
piston g is provided with a packing-ring hand has a rear projection i against which
the broadened end d¹ of the cocking-arm d can press; the piston is shot forwards
by a firing-spring k. A pin provided with a groove serves, in conjunction with
a lever n, which is furnished with a projection n' and is fulcrummed at n², to keep
the spring k cocked. The trigger o, which is pivoted at o', serves for disengaging
the lever n from the groove .
Laterally of the barrel is a latch p, which is acted on by a spring and whose
pin 9 engages in an entirely or partially perforated lug r on the barrel and thereby
holds the latter when it is turned up into position for firing. Any other suitable
device may, however, be provided for securing the barrel a.
When the barrel is turned down after disengaging the latch p or its equivalent,
the cocking-arm d presses against the rear projection i of the piston and thereby
pushes the pistong backwards, compressing the spring k. After again turning up
the barrel and pulling the trigger o, the pin is liberated by the lever n and the
piston k shot forwards. The separate cylindrical casing f for the piston g forms a
good guide for that piston for preparation of the lock which is thus rendered
possible.

Improvements in Air-guns.
I, OSCAR WILL, of Zella St. Blasii, Germany, Weapon-manufacturer, 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 :-
In an air gun according to this invention the tilting or turning down of the barrel

page_text: causes the air pump piston, which is completely enclosed in a separate cylindrical
casing to be moved backwards and the firing-spring thereby compressed or cocked,
so that the piston will be shot forward after the liberation of the firing-pin
connected therewith.
An air gun according to this invention is represented in longitudinal section in
Figs. 1 and 2 of the accompanying drawings,
Fig. 1 showing the piston uncocked that is to say in the position it assumes after
a shot has been fired; and
Fig. 2 showing the barrel turned down and the piston cocked.
Fig. 3 shows a cross section through the air-pump piston.
The barrel a is pivoted at 6 and is provided with an under-projection c to which
an arm d is connected. The arm d is at its rear end d' extended upwardly and
broadened and passes into the lock box g¹ which latter contains within it a separate
cylindrical casing f; in which the piston, y can be moved longitudinally. The
piston g is provided with a packing-ring & and has a rear projection i against which
the broadened end d¹ of the cocking-arm d can press; the piston is shot forwards
by a firing-spring k. A pin l, provided with a groove serves in conjunction with
a lever n, which is furnished with a projection a' and is fulcrummed at n², to keep
the spring cocked. The trigger o, which is pivoted at o¹, serves for disengaging
the lever n from the groove
Laterally of the barrel is a latch p, which is acted on by a spring and whose
ping engages in an entirely or partially perforated lug r on the barrel and thereby
holds the latter when it is turned up into position for firing. Any other suitable
device may, however, be provided for securing the barrel a.
When the harrel is turned down after disengaging the latch p or its equivalent,
the cocking arm d presses against the rear projection i of the piston and thereby
pushes the piston 9 backwards, compressing the spring k. After again turning up
the barrel and pulling the trigger o, the pin is liberated by the lever n and the
piston shot forwards. The separate cylindrical casing for the piston g forms a
good guide for that piston.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is:-
1. An air gun provided with a barrel a which is adapted to be turned down and
whose projection c when the barrel is turned down, by means of a cocking-arm d
both cocks a piston g, which is mounted in a separate cylindrical casing and is
provided with a projection i, and compresses the firing spring k, substantially as
herein before described.
2. My improved air-gun constructed, arranged, and operating as hereinbefore
described with reference to and shown in the drawings accompanying my Provisional
Specification.
