PROVISIONAL SPECIFICATION.
Improvements in or applicable to Air-guns.
I, MARTIN PULVERMANN, of Lancaster Buildings 26, Minories, in the City of
London, American and Continental Merchant do hereby declare the nature of this
invention (a communication to me by Friedrich Langenhan of Zeller Street, Blasü,
Thüringen, in the Empire of Germany, Gun Maker) to be as follows :—
This invention relates to improvements in or applicable to air-guns whereby the
barrel can be released in a simple manner and without requiring the use of two
hands as has hitherto generally been the case.
For this purpose the barrel is hinged to the stock in the usual manner but to
hold the same in its closed position I employ a spring lever catch fulcrummed just
over the trigger and adapted to engage in a recess in the barrel, the free end of
the lever coming under the thumb of the hand which fires the gun.
From this arrangement it will be obvious that the gun having been fired it is
only necessary to depress the free end of the lever catch to disengage the barrel.
Dated the 3rd day of March 1894.

Improvements in or applicable to Air-guns.
I, MARTIN PULVERMANN, of Lancaster Buildings, 26, Minories, in the City of
London, American and Continental Merchant, do hereby declare the nature of this
invention (a communication to me by Friedrich Langenhan, of Zella Street, Blasü,
Thüringen, in the Empire of Germany, Gun Maker) 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 improvements in or applicable to air-guns whereby the
barrel can be released in a simple manner and without requiring the use of two
hands as has hitherto generally been the case.
For this purpose the barrel is hinged to the stock in the usual manner but to
hold the same in its closed position I employ a spring lever catch so fulcrummed as
to engage in a recess in, or with a projection on, the barrel.
In order to enable the invention to be fully understood I will describe the same
by reference to the accompanying drawing, in which :-
Figure 1 is a sectional side elevation of a portion of the stock and barrel of an
air-gun constructed according to my invention the barrel being shewn in engagement
with the stock :
Figure 2 is a plan:
Figure 3 is a similar view to Figure 1 but shewing the barrel released from
engagement with the stock:
Figures 4 and 5 are a side elevation and a plan respectively shewing a modified
form of my spring lever catch.

page_text: a is the barrel which is hinged to the stock b, in the usual manner and c is my
lever fulcrummed (as shewn in Figures 1, 2 and 3) just over the trigger at d, and
provided with a spring e. The outer end of the lever c is advantageously formed
with an enlargement, adapted to engage with a correspondingly shaped recess 9,
formed in the barrel a, to hold the barrel and stock in their closed position the said
recess being reduced in width at the part nearest the stock to receive that portion
of the lever c adjacent to the enlargement f.
From this construction it will be obvious that the gun having been fired it is
only necessary to depress the free end of the lever c to disengage the barrel a
from the stock b thus dispensing with the need for employing both hands as has
hitherto been so frequently necessary. In closing the gun the recessed end of
the barrel a comes against the enlargement of the lever c and passes beneath
the same whereby the said enlargement enters the recess g under the action of the
spring e.
Instead of the enlargement f I sometimes provide the lever c, with a hook h at
its outer end, (as shewn in Figures 4 and 5) adapted to engage with a projection i,
formed on the barrel a.
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 :-
An air-gun having a spring lever catch fulcrummed on the stock and having its
outer end formed with an enlargement adapted to engage with a recess in the
barrel, or with a hook to engage with a projection on the barrel, substantially as
and for the purposes hereinbefore described and illustrated respectively in Figures 1,
2 and 3 and 4 and 5 of the accompanying drawing.
