page_text: I, WILLIAM HENRY BECK, of 115 Cannon Street, in the City of London,
Consulting Engineer and Patent Agent, 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, reference being had
to the accompanying two sheets of Drawings and to the letters and Figures marked
thereon, that is to say :-
This invention relates to new or improved mechanism for expelling cartridge
cases from firearms with longitudinal extractors, and especially to what are
known as Anson and Deeley hammerless guns with the Deeley expeller or ejector,
and the object of the invention is to substitute a sliding movement parallel to the
axis of the barrel for the pivoting movement of the Anson and Deeley apparatus.
The invention is applicable to guns with one or more barrels.
Figure 1 of the Drawings illustrates a double barrelled gun with the new or..
improved mechanism applied thereto, the gun being shown closed and after having
been fired, the expelling mechanism being set or cocked ready to act.
Figure 2 illustrates the gun open; the expelling mechanism having operated and
expelled the empty cartridge case.
Figure 3 is a horizontal section of an expeller or ejector for a double barrelled
gun the left hand mechanism only being shown set or cocked.
Figure 4 is a side view of same, the mechanism being shown set or cocked.
Figure 5 is a similar view, the mechanism being uncocked.
Figure 6 is a view from below of the frame plate without the expelling
mechanism.
Figure 7 represents the right hand hammer and its guide stem seen longi-
tudinally.
Figure 8 is a view of Figure 7 taken at the end of the guide stem.
Figure 9 is a side view of the expeller sear (gachette) and its spring.
Figure 10 is a view from below of the expeller sear and its spring.
The expelling mechanism is mounted in a small box or frame plate a, (Figures 1
and 6), the front part of which has two longitudinal cylindrical holes in which the
guide stems b b₁ of the hammers g move. A spiral spring d, placed round the
stem b, bears at one end against a shoulder of the cylindrical perforation, and at
the other end against a shoulder (Figure 7) of the stem b 6. The stem 6' carries,
at its hinder part, the hammer g and the piece i formed in one with the stem bb¹
The sear no, with its spring r, (Figures 9 and 10) is placed in an enlargement at

page_text: the back of the frame plate a and below the part 6 of the stem 66'; the spring r
is fixed on the arm o of the sear by a small screw 8, (Figures 9 and 10) which
takes into, and is moveable in, a hole in the frame plate. The sear no, with its
spring, pivots on an axis p, Figures 1, 2, 5, 6,-9 and 10.
ACTION OF THE MECHANISM.
The expelling hammer g is cocked by the backward movement of the stem m
of the extractor, a movement which is produced automatically in the usual manner
by the closing of the gun. The hammer g, with its guide stem 6 b¹, is pushed
forwards by the stem m, the spring d is compressed, and the sear o is forced by the.
spring into the bent u (Figures 1 and 7) of the stem 6 and holds the hammer g.
in the position shown in Figure 1. The sliding levert (Figures 1 and 2) releases
the hammer g by pressing against the arm n of the sear. The sliding lever t
assumes two positions as shown in Figures 1 and 2. By the action of the expeller,
the said sliding lever is pushed backwards by the piece i of the stem 6 b¹ (which
replaces the inclined plane of the "Deeley" expeller) and it comes against the main
spring, as shown in Figure 2. When the gun is fired, the main spring lengthens
and drives the sliding lever t forward, so that its front end comes under the arm n
of the sear o of the expelling mechanism, as shown in Figure 1. When the barrel
is turned down after the gun is discharged, as shown in Figure 2, the front end of
the lever tacts on the arm n, causing the sear o to leave the bent u, thereby
releasing the hammer g which is then projected backwards by the spring d, and
the empty cartridge case is expelled, as shown. If the gun has not been fired, the
cartridge is not expelled when the gun is opened, because the levert retains its
position against the mainspring and does not come in contact with the arm n of
the sear o.
The above description and relative Drawings, refer, as before stated, to a double
barrelled gun, but it will be understood that the expelling mechanism can readily
be adapted to guns with a single, or any other number, of barrels, by employing a
separate expeller for each barrel.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, I declare that what
I claim is:-
The new or improved cartridge case expelling mechanism consisting of a box or
frame plate a with a longitudinal cylindrical hole to receive the stem 6 6' and the
spring d; a stem 6 61 acted on by a spring d, and carrying at its hinder part an
expelling hammer g and the piece i; the sear n. o in the form of a two armed lever
arranged on an axis p beneath the stem bb', and the arm o of which, acted on by
a spring 7, holds the hammer 'g cocked, and the arm n of which is acted on by the
sliding levert to release the said hammer g; the piece i placed at the side of the
stem 6 b¹ and serving to push the sliding lever t against the main spring at
the moment when the expelling mechanism acts to expel a cartridge case, all
constructed, combined, and operating substantially as hereinbefore described, and
iflustrated in the Drawings hereto annexed.
