Improvements in and relating to Cartridge-ejectors for Fire-arms.
I, ERNEST ARBENZ, of Bucharest, in the Kingdom of Roumania, Manufacturer,
do hereby declare the nature of this invention to be as follows :-
My invention relates to a cartridge-ejector for fire-arms having a breech-block.
The improved ejector consists of two parts which are pivoted upon a bolt in the
loading chamber so that they can be operated by the breech block.
One of these parts, hereinafter termed the extractor is provided with an elongated
hole so as to enable it to slide a short distance up and down upon the aforesaid bolt.
The other part hereinafter termed the stop-piece, serves for stopping or disengaging
the extractor.
Both the extractor and stop-piece are actuated by the breech block which is
adapted to turn upon a pivot.
I place the stop-piece in an opening formed in the extractor which to a great
extent surrounds the said stop-piece. The extractor presents an angular shape,
one of its arms serving as a stop for the breech-block, whilst the other arm con-
stitutes a fork which engages with a groove formed in the cartridge.
The stop-piece is made of such a shape that when the breech block, is
closed the latter presses with its front surface against a curved surface of the
stop-piece, whilst when the said breech block is opened it presses with its
under side against an arm of the stop-piece. At its upper part the stop-piece has
a small notch which serves as a stop rest for a projection or stop-nose on. the
extractor, forming the end of an inclined surface the object of which will hereinafter
be explained.
In the loading, that is to say when the breech-block has been moved down the
extractor is turned backwards, in which case the aforesaid rest does not then
engage with the stop-nose. The extractor now rests with its inclined surface upon
the rest.
After the introduction of the cartridge the breech block is raised to the
position adapted for the firing, during which movement it presses first with its front
surface against the forked part of the extractor, and next against a curved surface
of the stop-piece. In this manner the extractor is caused to pass to such a position
that its fork will be exactly below the groove formed in the cartridge casing.
Then the breech block also turns the stop piece a short distance causing the edge
of the rest to press against the inclined surface in such a manner that the extractor
will be raised a little. It is only at this moment that the latter engages with the
groove provided in the cartridge casing. The stop-piece is pressed forward by the
breech block until the above mentioned stop-nose reaches the rest and bears upon
the same.
Then the extractor is stopped and the block closes the breech.
After the firing the breech block is moved down again. It then strikes upon
the extremity of the lower arm of the extractor, and as the latter now forms a
whole with the stop-picce it is turned a certain distance without changing its
position vertically so that the cartridge embraced by the fork of the same is pulled
out. The fork embraces the cartridge only for a short distance during the
ejection until the underside of the breech block reaches the arm of the stop-
piece. By turning the latter the breech block then causes the rest to be drawn
from below the stop-nose so that the extractor by reason of the elongated opening
will descend a little and slide from the groove in the cartridge casing. Thus the
latter is released and can fly off without meeting any obstacle.
If after the firing and prior to the ejection of the cartridge case the extractor
should accidentally fall from the rest, the breech block in its descent would force

page_text: the stop-piece to such a position as to couple the stop-piece and extractor together
before the breech block strikes upon the lower arm of the latter in order to effect
the extraction of the cartridge case in the above described manner.

Improvements in and relating to Cartridge-ejectors for Fire-arms.
I, ERNEST ARBENZ, of Bucharest, in the Kingdom of Roumania, 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 :-
My invention relates to cartridge-ejectors for fire-arms having a pivoted breech-
block.
The improved ejector consists of two parts which are pivoted upon a bolt in the
loading chamber so that they can be operated by the breech block.
In the accompanying drawings
Figure 1 shows the ejector in the position which it occupies when the block is
in the position for loading.
Figure 2 shows the ejector in the position in which the block closes the breech
after the loading, the intermediate position indicated in dotted lines corresponds to
the movement of the block during the ejection.
Figures 3 and 4 show the pivoted cross-piece in front and side elevation.
Figures 5 to 7 show the turning and sliding part of the ejector in rear, side
and front elevation.
The ejector consists of the two parts A and B arranged in the loading chamber
so as to turn upon a bolt C.
The part A or stop piece is adapted to turn upon the bolt C and the part or
extractor B is provided with an elongated hole 3 so as to enable it to slide a short
distance up and down upon the aforesaid bolt. The part A. serves for stopping
or disengaging the extractor. Both the extractor and stop-piece are actuated by
the breech block which is adapted to turn upon a pivot c.
The stop-piece A is arranged in an opening or recess formed in the extractor
which to a great extent surrounds the said stop-piece. The extractor is made
in the shape of a bell crank lever Figures 5 to 7 one arm 1 of which serves as
a stop for the breech block a whilst the other arm constitutes a fork which
engages with a groove formed in the cartridge.
The stop-piece A. is made of such a shape that when the breech block a is
closed the latter presses with its front surface 10 10 against a curved surface 8
of the stop-piece whilst when the said breech block is opened it presses with its
under side 11 against an arm 9 of the stop-picce. At its upper part the stop-
piece A has a small notch which serves as a rest for a projection or stop nose 6 on
the extractor, forming the end of an inclined surface the object of which will
hereinafter be explained.
In the loading that is. to say when the breech block a has been moved down as
in Figure 1 the extractor is turned backwards, in which case the aforesaid rest 7
does not then engage with the stop nose 6. The extractor now rests with its
inclined surface 5 upon the rest 7. After the introduction of the cartridge the
breech block is raised to the position for firing, shown in Figure 2 during which
movement it presses first with its front surface 10 10 against the forked part 2.of
the extractor, and next against a curved surface 8 of the stop-piece. In this
manner the extractor is caused to pass to such a position that its fork will be

page_text: exactly below the groove formed in the cartridge casing b. Then the breech
block a also turns the stop piece A a short distance causing the edge of the rest to
press against the inclined surface 5 in such a manner that the extractor will be
raised a little. It is only at this moment that the latter engages with the groove
provided in the cartridge casing. The stop-piece is pressed forward by the breech
block until the above mentioned stop nose 6 reaches the rest 7 and bears upon the
same. The extractor is then stopped as shown in Figure 2 and the block closes
the breech.
After the firing the breech block a is moved down again into the position shown
in Figure 1 it then passes through the intermediate position indicated in dotted
lines in Figure 2 and strikes upon the extremity of the lower arm 1 of the extractor B
and as the latter now moves together with the stop-piece A it is turned a certain
distance without changing its position vertically so that the cartridge embraced by
the fork 2 is pulled out. The fork embraces the cartridge only for a short distance
during the ejection until the under side of the breech block reaches the arm 9 of
the stop piece. By turning the latter the breech block then causes the rest to be
drawn from below the stop nose 6 so that the extractor B by reason of the elongated
opening 3 will descend a little and slide from the groove in the cartridge casing.
Thus the latter is released and can fly off.
If after the firing and prior to the ejection of the cartridge casing the extractor B
should accidentally fall from the rest, the breech block a in its descent would force
the stop-piece to the position Figure 1 and thus couple the stop-piece A and
extractor B together before the breech block strikes upon the lower arm of the
latter, in order to effect the extraction of the cartridge casing in the above described
manner.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed, I declare that what I
claim is-
First. An ejector for cartridge cases in fire arms, consisting of two parts A
and B the former of which is adapted only to turn upon the bolt C, and the second
to turn and slide, as hereinbefore described and represented in the drawing.
Second. An ejector for the cartridge cases in fire arms, consisting of the
extractor B and the stop-piece A adapted to turn therein, in combination with the
block a which in the upward movement turns the stop piece A by means of
the surface 10-10, and further with the inclined surface 7 on the ejector, whereby
the stop-piece A raises the extractor B a little for the described purpose, after
this ejector has been moved by the block a to the proper position, as represented
and described.
Third. In an injector for cartridge cases in fire-arms the extractor B and the
stop-piece A with the rest 7, into which the nose at the end of the inclined
surface 5 fits, in such a manner that in the firing position of the block a the two
parts A and B are coupled, as represented and described.
Fourth. In an ejector for cartridge cases in fire arms, in combination with the
extractor B and the stop-piece A the former of which is adapted to turn and slide
upon the bolt C and the second only to turn, the stopping device 6, 7 and the
inclined surface 5, and the stop 9, against which, during the ejection, the block
strikes later than upon the arm 1 of the extractor, as represented and described.
Fifth. An ejector for fire arms having a breech block consisting of two angular
parts (A and B) one of which (A) is adapted to turn only upon the common
journal (C) and the other (B) to turn and slide, in such a manner that the block (a)
turns the stop-piece (B) thereby raising the extractor with the fork (2) into the
groove in the cartridge case and effecting the fixing of the same by means of a
cavity (7) in the stop-piece whilst the extraction of the casing is effected by the
striking of the block upon the lower arm (1) and the consequent turning of the
locked extractor, the extractor holding with its fork (2) the cartridge until by

page_text: the striking of the block upon the arm (9) of the stop-piece, the locking is dis-
continued and the extractor falls a short distance.
