Improvements in Magazine Air Guns.
I, THEODOR HORNHAUER of Schmiedegasse, Dresden, Germany, Gun Maker,
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 sharp firing magazine air gun of simple construction
and great durability.
In the accompanying drawing
Fig. 1 is a longitudinal section shewing the main parts of the air gun of this
invention.
Fig. 2 is a view of the front end of the air cylinder and forked extension h.
Fig. 3 shews the back or pivotted end of the gun barrel.
Figs. 4, 5, 6, respectively a side view, an end view and a sectional view with the
gun barrel laid open at an angle with the air cylinder.
Figs. 7 to 22 relate to details.
a is the barrel of the gun in the form of a steel double tube (Figs. 1, 16) in the
upper bore of which is inserted the firing barrel c, the lower bore d forming the
magazine. (Figs. 1, 17, 18) is a metal attachment applied to the barrel a by
sliding this into the same. e (Fig. 1) is a plug or screw by which the magazine
is opened and closed at the front or filling end. f the air cylinder from the front
end of which projects a forked extension for the reception of the back end of
and to which is pivotted on a stud i, the barrel a comprising the firing barrel cand
magazine d. The air cylinder f has in its front end a taper or countersunk hole k
is
for the reception of the shot which, when the hollow cylindrical piston y sprung
is formed of a steel
forward, is acted upon by the compressed air. The piston
tube with a closed end to which is fixed by a screw, a packing disc l. With the
gun in the closed up position (Fig. 1) the back end of the double tube or barrel a
bears tightly against the end g of air cylinder and in said back end is provided
a recess n for the reception of, and in which may move, a spring r, shewn in detail
in Fig. 11 and having for object to prevent shot falling undesired from the
magazine. Its short left hand leg is fixed in a hole o (Fig. 8), the middle part is
located in a groove p, and the right hand leg in the recess n so as to project some-
what from the same, and so as in the normal or state of rest position to bear
downwards and project over the magazine sufficiently to prevent the exit of shot
from the same.
9 is a recess in the fork in which a flat springs is fixed by
means of a screw (Figs. 5, 9, 15, 19).
In the open position shewn in Figs. 4, 5, the gun is cocked in the manner and
by the means shewn and described in my previous Patent Specification No. 7932
of this year.
In straightening the parts (Fig. 6) the spring r comes upon the
springs (Fig. 9) and in the further straightening of the same, the spring r is raised
and the magazine d thereby opened at the moment it comes opposite the hole k
(Fig. 15) whereupon a shot passes into said hole and the spring r then springs back
again over the magazine. In fully straightening or closing up the gun the shot
is pressed by the back end of the firing barrel c into the hole k so that no air can
escape past the shot.
The parts shewn in the drawing and which are only cursorily referred to herein,
or only so far as is necessary for the description of this invention have the same
object and operate in the same manner as the like parts described in my aforesaid
previous Patent Specification.

page_text: t (Figs. 1, 7) is a spring snap bolt for holding the gun barrel and the air vessel
in their relative positions when the gun is closed up.
The air gun of this invention presents the advantage that in moving the barrel
to open the gun the piston in the air cylinder may with the aid of a push rod be
cocked, but other kinds of air guns may be provided with the described repeater
arrangement.
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 is :-
1. Magazine air guns in which the magazine is open at the back end in such a
way that a shot passes direct out of the same into the end of the air cylinder and
is there held fast, substantially as described and shewn.
2. A magazine air gun of the kind referred to in Claim 1, in which the magazine
is held normally closed at the back end by a spring or sliding part r and is opened
only during the time the magazine passes in front of the hole k in the end of the
air cylinder, substantially as described and shewn.
3. A magazine air gun in which the casing of the firing barrel and the magazine
are drawn out of one piece of steel tube (Fig. 16) and the attachment connected
to the double tube a without soldering or brazing, substantially as described and
shewn.
4. A magazine air gun in which the cylindrical air piston is formed of a steel
tube closed in at the end, substantially as described and shewn.
5. A magazine air gun in which the end of the air cylinder f is provided with
two tongues forming a fork which tongues are fixed by soldering or rivetting to
a fork-like extension at the end of said air cylinder, for the purpose specified
substantially as described and shewn.
6. A magazine air gun in which, between the shot to be fired and the compressed
airway, there is no joint by which the air can escape, substantially as described and
shewn.
Dated this 4th day of December 1895.
