PROVISIONAL SPECIFICATION.
Improvements in the Breech Closing Action of Air and like Guns.
I, THEODOR BERGMANN, Manager of Eisenwerke, Gaggenau, Gaggenau, Baden,
do hereby declare the nature of this invention to be as follows:-
The present invention relates to the breech closing action for gun barrels in air
and like guns.
According to this invention the upper face of the barrel and the extension or
grip fall in the same plane while the sight may be on the air barrel or on the
extension or grip.
The extension or grip is in one form of the invention provided with one or two
arms pivoted on the gun barrel and normally held up flush therewith by spring
action while the rear end which may carry the sight embraces a projecting pin on
the air barrel or engages therewith or where the grip is in separate parts they may
engage in notches in the air barrel.
If preferred the grip may be pivoted to the air barrel and the two hooked arms
in this case engage with corresponding notches in the gun barrel and are normally
held in this position by the action of a spring resting on the air barrel or the forms
may be combined by operating the extension grip pivoted on the gun barrel by a
spring catch pivoted on the air barrel.
Dated this 1st day of April 1893.

page_text: Figs. 6 and 7 are modified forms of the closing device and
Fig. 8 is a plan of Fig. 7.
In place of a two armed hook closer as represented in Figs. 1, 2 and 3 a one
armed hook may be employed, and such a construction is seen in Fig. 6. If the
book represented in Fig. 5 is formed with one arm, then it shews the reverse of the 5
arrangement illustrated in Fig. 6. In Figs. 7 and 8. a catch arrangement for
holding the closing device is represented. In the arrangement represented in
Figs. 1-and 2 there is formed on the end of the air chamber a the projection b
behind which on the closing of the gun barrel c the closing device or part & firmly
seats the projection being embraced by the two arms e and e' which lie in grooves
in the head of the breech and are pivoted on the pin g and held by two springs h,
Fig. 1, which lie below it. In this position the sight is carried either by the
closing device or part d itself, see Fig. 1, or at the front of the same as shown in
Fig. 3 in which figure the projection b is divided into two parts which carry between
them the sight the part à being divided as shown to engage with the projections.
The parts d may carry pins n which engage with holes, in the wall of the air
chamber-see n- Fig. 1-and
n, n', Fig. 2, or the air chamber may carry the pins
and the part d have the holes. In the arrangement represented in Figs. 4 and 5,
there is passed through the projection b a
e and e¹ there are two projections m
which on the closing of the gun, catch in two recesses on either side of the head of
the breech and hold the latter.

In the arrangement shewn in Figs. 1, 2 and 3 the breech closer is caused to open
by lifting the part d. In the arrangement shown in Figs. 4 and 5-by depressing
down the part d said part d being kept in its locked position by the spring o which
lies under it.
In the arrangement represented in Figs. 7-and-8 there is on the air chamber a a
catch lever D pivoted on the pin a, so arranged that its one end reaches under
the projecting end of the part d, and engages in a recess in same and its other end

the gun it is only necessary to press down the free end of the lever D' by which the
part d is rocked on its pivot g and thus opened.
In Fig. 6 the part & carries a projection m which engages behind a projection 6'
on the air chamber (or it may engage with a recess in same) the part d being
pivoted at g on the breech fand held in a locked position by means of a spring o
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
"claim is :-
.
1. A breech-closing apparatus for the barrel of air-guns of a two-armed type, in
which the upper edge of the barrel lies on a level with the upper edge of the head
of the breech-closing apparatus substantially as described...
2A-breech-closing apparatus for the barrel of air-guns..of a one-armed type
consisting of a hooked-shaped part, which either catches behind a projection or
snaps into a recess arranged substantially as described.
"
3.A catch lever arranged on the air-chamber'operated by a spring, said lever
engaging under the projecting end of the closing device substantially as described.
4. The improvements in the breech closing action of air and like guns
substantially as described and illustrated in Figs. 1 to 8 of the drawings.
