page_text: I THOMAS PERKES of No. 70 Osnaburgh Street Regents Park London 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 improvements in the actuating mechanism of the ejectors
of guns rifles and other breech loading-small-arms that turn upon a hinge for opening
or closing the breech end of the barrels.
My invention consists in. employing either rods or rocking bars which are fitted
to any convenient part of the action or to the lock plates and are operated either by
the tumbler or main springs or by suitable cams and springs placed in any convenient
position.
Such rods or rocking bars are furnished with projections or recesses or with
intermediate limbs so as to engage with the lock at any convenient point.
When rods are employed they may be worked either by the fore end or in any other
convenient manner and when rocking bars are used they are so arranged that they are
in contact with and are actuated by the tumblers or main springs.
Figs. A A illustrate the application of my invention to a self extracting gun
wherein the actuating mechanism at the fore end is actuated by a rod 1 engaging with
and operated by the main spring 2 of the lock-The rear end of such rod has a recessed
projection 4 formed thereon into which a stud 5 formed on the main spring takes and
works up and down as the tumbler or hammer rises or falls. The contraction of the
main spring draws the rod backwards while the expansion of such spring urges the
rod forwards. In the drawing the tumbler or hammer is shewn in the fired position
and the rod in position to act on the ejecting mechanism when the gun is opened. As
the tumbler or hammer goes to full cock the rod is drawn back into a neutral position
as shewn in Fig. A' thus allowing the gun to be opened and closed freely.
Figs. B, B1, B illustrate the application of a rod to the tumbler of the lock in
order to operate the actuating mechanism at the fore end-1 is the rod which has a
collar 2 formed thereon about midway-The portion of the rod above this collar is
reduced in thickness and filed. away so as to impart a certain degree of elasticity
thereto. A coiled spring 3 is mounted thereon one end of which abuts against the
before mentioned collar and the other against a shoulder 4 formed on the recess in the
action wherein the rod works. A tooth or stud 5 is formed on the rear end of the
rod. This tooth interlocks with the fore arm or crane of the tumbler wherein a
recess 6 is formed in order to receive the same as shewn at Fig. B' the front edge of the
fore arm or crane is bevilled off to allow the tooth to readily pass over the same.
When the hammer falls on the nipple of the gun the tumbler releases the rod and the
coiled spring expanding the rod is urged forward into position ready to actuate the
ejecting mechanism when the gun is opened as shewn at Fig. B₁-The tumbler then
returns to the rebound position the fore arm or crane thereon forming a bearing or

page_text: abutment against which the rod presses when it is acting on the intermediate catch
piece 6 while opening the gun it being then forced back into the recess in the for
arm or crane of the tumbler as shewn at. Fig. B-The rod is forced back either by the
fore end or the catch piece according to the construction of the gun. When the rod
is in the forward position as shewn at Fig. B¹ it is ready to act on the ejecting
mechanism either at half or full cock and when in the position shewn in Figs. B B' it
is neutral either at half or full cock.
Fig. C shews the ejecting mechanism actuated by a rod 1 which is operated by a
stud 2 on the swivel 2 of the main spring-This stud engages with a projection or
recess 3 formed at the rear end of the rod 1. On the tumbler 4 being placed at full
cock as shewn the swivel stud 2 that takes into the hook of the main spring 5 travels
in the recess 3 formed on the rod and so withdraws it into a neutral position. The
expansion of the main spring on the falling of the tumbler 4 causes the rod 1 to be
carried forward into an ejecting position by the action of the swivel stud 2 thereon-
The gun is shewn open in the drawing the rod 1 being neutral and passing freely the
point of the catch piece 9 the ordinary cam 7 acting upon the extractor 8 in the usual
manner.
Figs. D, D¹, D' shew a modification of the arrangement described and shewn at
Fig. B. Such modification consists in forming a curvilinear groove or recess 2 in the
tumbler 3 wherein the tooth or stud 4 on the rear end of the rod works eccentrically
thus dispensing with the use of a coiled or other spring and obtaining the advantage
of a double action as when the tumbler rises the rod is withdrawn by the downward
travel of the stud in the groove or recess while when the tumbler falls the rod is urged
forward by the contrary action of the stud or tooth in such recess.
In the drawing
Fig. D the tumbler is shown at bearer the rod then being in an ejecting position-On
going to full cock as shown in Fig. D' the stud 4 on the rod 1 travels in the eccentric
groove or recess 2 and so withdraws the rod backward into a neutral position as also
shewn in Fig. D¹ Fig. D shews a plan view of the recessed tumbler with the actuating
rod 1 locked therein.
Figs. E E' shew a method of actuating the ejectors by a rod 1 operated by the
sear 13 the gun having been opened and the rod pushed back into a neutral position
as hereinbefore described with reference to Figs. B B', B. A projection 4 on the
end of the rod passes over an extension 13 on the nose of the sear 13 the tumbler 3
being at full cock and the sear 13 being in the bent. When the sear is withdrawn
from the bent it releases the rod which is then pressed forward into an ejecting position
by the coiled spring 8 as shewn in Fig. E' the extension on the sear acting as an
abutment to resist the rod when acting upon the ejecting mechanism.
Figs. F F shew the actuating rod 1 with projection 4 acting on a lever 15 which is
operated by the lower arm of the main spring 2-When the rod is actuating the
ejecting mechanism it passes over such lever and assumes a neutral position as shewn
at Fig. F' either at half or full cock-The lower arm of the main spring 2 lies in a
recess 16 formed at the rear end of the lever. The contraction of the main spring 2
on the tumbler when going to cock acting upon the rear end of the lever causes it to
resist the rod either at half or full cock thus keeping the rod in position. When the
tumbler or hammer falls upon the striker the main spring 2 acting upon the rear end
of the lever 15 releases the rod 1 which is urged forward into position by the coiled
spring 8 ready to act upon the ejecting mechanism while the tumbler carries the main
spring 2 to the rebound position-The lever 15 is then in position to resist the return
motion of the rod 1 as seen in Fig. F which indicates it in an ejecting position either
at half or full cock-The lever 15 herein shewn may be dispensed with and the rod as
herein before described with reference to this figure made to act upon the main
spring 2 a suitable stud or projection being formed thereon to engage with the rear
end of the rod as shewn at Fig. A. In these two figures I have shewn the improved
construction of the actuating mechanism at the fore end already described in reference
to Fig. C. A further improvement therein consists in mounting such mechanisin
either on a plate on the fore end or in a box attached to the fore end the plate or
box being so arranged that when the gun is opened the back of such plate or box acts
:

page_text: as a lever to force back the rod into a neutral position thus simplifying the position of
the actuating mechanism and facilitating the adaptation of my present invention to
ordinary and other guns. Figs. F F shew the actuating mechanism at the fore end
BO mounted.
Fig. G shews the actuating rod operated by a cam. In this figure the gun is
shewn at full cock ready for firing the rod 1 being drawn into a neutral position by
means of a cam 19 the lower end of which takes into a recess at the rear end of the
rod 1. The cam is pivotted either on the action or the lock plate and is connected by
a pin or stud to the tumbler 3. When the tumbler falls it actuates the cam 19 and
urges the rod forward into position to act on the ejecting mechanism. The cocking
of the tumbler acting upon the cam 19 withdraws the rod into a neutral position.
Figs. H H¹ shew a second modification of the arrangement shewn at B whereby I
dispense with the groove or recess in the tumbler the rod 1 being arranged to gear
with the abutment 4ª on the tumbler 3 as shewn. The drawing H shews the gun
closed and the tumbler in the fired position-the rod having been released by the
falling of the tumbler and being urged forward by the coiled spring 8 into position to
act upon the sear catch 6. On opening the gun the rod 1 is pushed back against the
abutment 7 of the tumbler 3 over which the rod 1 passes into a neutral position after
having acted upon the ejecting mechanism as shewn at Fig. H¹.
Figs. J J shews rod 1 with an intermediate lever 15 jointed at rear end acting
in conjunction with the main spring 2. The contraction of the main spring 2 draws
the rod 1 into a neutral position as shewn while the expansion of such main spring 2
releases the rod 1 into an ejecting position the lever 15 at rear end of rod is provided
with a spring 18 to enable the intermediate lever to pass over a projection 5 on main
spring which projection forms an abutment that resists the return motion of the rod
and by so doing ensures its actuating the ejecting mechanism. The mode of actuating
the lever and rod is the same as already described in Figs. F and F¹.
Fig. K shews a rocking bar 1 actuated by the main spring 2 the rocking bar 1
having been locked by the contraction of the main spring so as to enable it to
act upon the sear catch and then release the ejecting lever which acts upon the
extractor 10-This rocking bar 1 is connected with the main spring 2 at its rear ond
which engages in a recess 4 formed thereon. A spring 18 is fitted to the action
which spring locks the bar 1 when at the point of acting upon the ejecting mechanism.
A projection 20 on this spring 18 comes in contact with a corresponding incline on
the main spring 2 and withdraws the locking spring 18 on the tumbler being at cock
thus allowing the bar 1 to rock freely when at full cock and permitting the gun to
open and shut without affecting the ejecting mechanism.
I would here observe that the rods as shewn at Figures B and H are equally
applicable to the main spring which is suitably formed to engage with them and such
rods may be of any convenient form-The various arrangements herein before
described are shewn as applied to what are technically termed fixed main springs that
is to say the stand side of the spring is studded into the plate in the ordinary
manner Such arrangements however are equally applicable to main springs which
have a sliding movement on the rising or falling of the hammer or tumbler-The
cams or levers may be fitted either to the lock plates or to the action.
I would also point out that the various arrangements hereinbefore described and
shewn are to be understood as being applied to each barrel of a self ejecting gun.
My invention is equally applicable to hammer and hammerless guns.
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
