rels of the gun have been ñred the shell will be
mechanism for a so-called under-and-over gun,
although it will be understood that the principles
of the invention are applicable to guns of other
types.
As shown, the ejector mechanism is applied to
a shotgun of the under-and-over type having
one barrel mounted above the other. Such guns
are commonly provided with a barrelsection piv
oted to the action frame and controlled by a le
ver so that the gun may be broken for ejection
of the iired shells and reloaded. It is, of course,
desirable that after one barrel of the gun has
been ñred this shell may be ejected from the bal'
rel so that it may be reloaded without the ejec
tion of a cartridge remaining in the other barrel,
and this action should be eiîected regardless of
which barrel has been ñred. Likewise, if both
barrels have been ñred, both shells should be
ejected when the gun is broken.
In the past the ejecting mechanism ‘nas usual
'.y been mounted in the barrel section of the gun,
and in its usual form comprises a spring-actu
ated ejector hammer controlled by a scar or the
like, the scar being released when the gun is
broken. In the present invention the greater
part of the ejector mechanism is mounted in the

This invention relates to ejector mechanism
for firearms, and more particularly to an ejector

ejected from the ñred barrel.
To these and other ends the invention consists
in the novel features and combinations of parts
to be hereinafter described and claimed.
In the accompanying drawings:

of a ñrearm adjacent the breech thereof, show

Fig. 7 is a sectional view at the breech end of
the barrel section, on line ‘I-'I of Fig. 5.
To illustrate a preferred embodiment of my in
vention I have shown a ñrearm comprising a bar
rel section I0 and an action frame II. As shown
in Fig. 7, for example, the barrel section com

action frame, close to the action mechanism con
the other, as is usual in an under-and-over gun.

move the cooking lever from the position shown '
in Figs. 1 'and 4 to the position shown in Fig. 6,
thus moving the hammers to ’cocked position
whenever the gun is fully opened. In other words,
whenever the gun is opened both hammers are
moved to cocked positions in which the tail por
tions 32 and 33 will be engaged and held in such
positions by the sears 34 and 35, unless, of course,
one or both of the hammers have not been fired
and are already in cocked position.
The ejectors are slidably mounted in the bar
rel section, one at each side thereof, and consist
of body portions 55 having the ejectors 5l at their
rear ends, one of which serves to ejectV the shell
in the lower barrel and the other in the upper
barrel (Fig. 7). At their forward ends the body
portions 59 are provided with laterally turned
ends 52 adapted to be engaged by the upper ends
of levers 53 pivoted at 54 in the side walls of
the forearm, as shown more particularly in Fig.
2. It will be understood that the ejector mecha
nism is duplicated at each side of the gun,- and
hence it will be necessary to refer in this de
scription to that on one side only.
Slidably mounted in the side wall portions I5
and l5 of the fore part of the action frame are
rods 55, the forward ends of which engage the
cam-shaped lower ends 56 of the levers 53. The
rear ends of these rods 55 extend into the action
frame and are there provided with heads 51 hav
ing therein notches 58 within which are engaged
the ends 59 of ejector hammers 60 pivoted at 5|
to the action frame.
Each ejector hammer is provided with a rear
'wardly extending arm 62 having a head portion
‘63, and is urged to forward position by the spring
54, which is the position shown in_Fig. 1_. for ex
broken by swinging the lever 22 about its pivot
in the usual manner, thus allowing the barrel
section to swing upwardly, as shown in Fig. 6.
During this movement the rod 4| is cammed
rearwardly by the cam face 45 of the abutment
44 to move the cooking lever 38 rearwardly, and
thus force the main hammers rearwardly against
the tension of the springs 28 and 29 to cocked
position, the full cocked position being shown in
Fig. 5. During this rearward movement of the
main hammers the lugs 51 engage the forward
ends of the heads 53 of the ejector hammers and
swing the ejector hammers in a clockwise direc
tion about their pivots 6I and against the action
of the springs 54. In Fig. 6 of the drawings I
have shown the position of the parts just before
the main hammers reach a fully cocked position,
and it will be seen that the lug 61 on the hammer
toward the observer is about to ride over the end
of the head 63 of the adjacent ejector hammer.
Slight additional movement of the cooking lever
38 to fully cock the main hammers will move the
lug 61 rearwardly to a sufficient extent to move
oft the shoulder 55a and release the head 63 and
allow the ejector hammer 60 to be propelled in an
anti-clockwise direction by its spring 64.
The arm 59 of the ejector hammer lying in the
recess 58 propels the rod 55 forwardly to act on
the lower end of the lever 53 and drive the ejector
outwardly, as shown in dotted-line position in
Fig. 6. The spring 54 is sufficiently strong to
move the ejector hammer with a snap action and
thus drive the ejector rearwardly with suilicient
force to eject the exploded shell from the barrel.
It will be apparent that this ejecting action
takes place only when the gun is opened, with
the hammers in their forward or uncooked posi~
tion in which they will lie after the gun is fired.
If the gun is broken when the main hammers are
in cocked position, as shown in Fig. 5, the ejector

will have no eiîect on the main hammers when
they are already cocked, and likewise the ejector
hammers will remain stationary. In the latter _
event, however, the rod 55 is held in its forward
position by the spring ed, and will cooperate with
the lower end ci' the lever 53 to move the ejector
rearwardlyT with a _gradual motion, which, while
not ejecting the shell, will extract it to a suffi
cient extent so that it may be easily withdrawn,
as is desired when the gun is to be unloaded.

It will be appreciated that, as the ejecting
mechanism is duplicated at both sides of the gun,
as are also the lugs 5l upon the main hammers,
the cartridges Will be ejected only after they
have been iired. For example, if the lower barrel
has been iired but not the upper one, only the
lower hammer will be in position to cock and
reîease the ejector hammer associated therewith,
while the ejector hammer on the other side will
remain stationary and merely move the shell in
the upper barrel outwardly to a position where
it can be withdrawn, and the converse will be
true if the upper barrel only has been fired.
Moreover, if both barrels have been fired, both
shells will be ejected.
It will be apparent that I have provided a
simple and efiicient ejecting mechanism which
avoids the employment of sears for holding the
ejector hammers in cocked position, and that the
ejector hammers are both cocked and released,
or drawn back and released, by continued move
ment of the hammers in the same direction to
cocked position, which occurs each time the gun
is fully opened, provided, of course, the hammers
are not already cocked. By simplifying the eject
ing mechanism it may be conveniently mount

hammers may be directly actuated thereby. The
