PROVISIONAL SPECIFICATION.
Improvements in Ejecting Mechanism for Drop Down Sporting
Fire-arms.
I, EDGAR HARRISON of 142 New Bond Street, in the Parish of St. Georges
Hanover Square, in the County of London Gunmaker, do hereby declare the nature
of this invention to be as follows:-
In drop down sporting fire-arms a number of devices have been invented whereby
on opening the gun the cartridge or cartridges which have been fired are ejected
whilst the loaded cartridge or cartridges are loosened but remain in the barrels
unless withdrawn by the hand.
The extractor legs are operated either by a helical spring or spring plunger or
by a tumbler in the fore part or action.
Now my present invention relates to means for operating on this tumbler in the
fore part or action or on the extractor leg, in such a manner that on the falling of
the hammer, the corresponding cartridge is ejected on opening the gun, and part of
my invention has especial reference to an invention for which a Patent was granted
to me No. 16214 of 1886.
According to one arrangement of my present invention I employ a spring rod,
having a spring piece at its rear end, which spring rod engages with the tumbler or
other movable part. On the rebound or on the re-cocking of the hammer, after firing,
this spring rod is pressed forward through the knuckle joint and engages, on the
opening of the gun, with a sear, which sear it withdraws from the tumbler in the
fore part or from the extractor leg or spring plunger. In some cases I cause
the spring rod to press against the fore end tumbler on the return of the hammer,
which overtilts the said tumbler and leaves the tumbler cocked, till, on the opening
of the gun, the lower end of the tumbler coming against a projection in the
action is tilted back and forces back the extractor leg. Or the spring rod may tilt
back the tumbler which has been previously tilted over in the closing of the gun.
Or the spring rod may partly or wholly cock the fore end tumbler the sear being
withdrawn on opening the gun.
The spring rod may be pressed forward so that it presses a sear into bent; or
retains a sear in bent, or a tumbler at cock, until the gun is opened sufficiently
when the sear is either actuated by the sliding rod or a spring. In place of the
sliding rod one or more levers fulcrummed in the action may be employed.
In a
"bar lock" I make use of the rocking movement of the mainspring to
actuate the tumbler in the fore part, or the sear of the extractor leg or tumbler.
Or the movement of the mainspring may allow a spring or other limb to effect the
above.
The rocking of the mainspring may directly, or by the medium of a lever or rod
or both, overtilt the fore-end tumbler, or it may partially or wholly cock the said
tumbler.
The fastening bolt, or a connection to said bolt, may be used to actuate the
extractor by overtilting the fore end tumbler, or cocking same when the gun is
fired, so that the said tumbler is retained till the gun is sufficiently open, and the
tumbler is then released by a projection on the tumbler or to the end of the sear
coming to the end of the slot in which it has been travelling.
The movement of the mainspring can also be utilized to operate the tumbler

COMPLETE SPECIFICATION.
Improvements in Ejecting Mechanism for Drop Down Sporting
Fire-arms.
I, EDGAR HARRISON of 142 New Bond Street, in the Parish of St. Georges,
Hanover Square, in the County of London Gunmaker do hereby declare the nature
of this invention und in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement :-
In drop down sporting fire-arms, a number of devices have been invented whereby
on opening the gun the cartridge or cartridges which have been fired are ejected,
whilst the loaded cartridge or cartridges are loosened, but remain in the barrels
unless withdrawn by the hand. The extractor legs are operated either by a helical
spring or spring plunger or by a tumbler in the fore part or action.
Now my present invention relates to means for operating on this tumbler in the
fore part, or action, or on the extractor leg, in such a manner that on the falling of
the hammer, the corresponding cartridge is ejected on opening the gun, and part of
my invention has especial reference to an invention for which a Patent was granted
to me No. 16214 of 1886..
My invention will be readily understood by the following description having
reference to the accompanying drawings.
Figure 1 is a sectional view of a gun of the "bar lock" type, and having my
improvements applied thereto.
Figure 2 is a view of the same action in the "cocked" position;
Figure 3 is a partial plan showing the arrangement of slots in the action and
Figure 4 is a perspective view of the sear shown detached.
In Figure 1, the parts are shown in the position they would occupy,
after the gun
had been fired, and in Figure 2 the parts are as aforesaid shown in the cocked
position.
A is the tumbler or hammer which is actuated by the spring B fulcrummed at B¹.
C is a lever fulcrummed in the action, the rear arm of which engages with the
spring B and the front arm with the sear D, which latter is fulcrummed in the fore
part, and the front arm of said sear D engages or not, according as to whether the
gun is fired or not with the extractor plunger or leg E.
The action of these plungers or extractor legs E has been fully described in the
Specification of my Patent No. 16214 of 1886 and is such that to eject a cartridge
shell after firing, the leg E is intercepted on opening the gun, and when open to
the full extent or nearly so, the extractor leg is let go, so ejecting the cartridge.
In the case of a cartridge not having been fired the extractor is not intercepted,
and so on the opening of the gun, the extractor travelling slowly up the face of
action loosens the cartridge without ejecting it.
The object of a part of this invention is to intercept this leg E or not to intercept
it, as the case may be, and in this arrangement the lever D is employed to
intercept it.
When the gun has been fired, the spring B rocking on its fulcrum B¹ raises the
rear end of the lever C, and the front end of the said lever C then depresses the rear
end of the sear D, which turning on its fulcrum, raises its front part, so intercepting
the extractor leg and holding it forward until the said sear D is rocked by the
part D (see the detached view Figure 4) coming to the end of a slot F Figure 3,
in which it has been travelling, and the extractor is thus suddenly let go, and the
exploded shell ejected.

page_text: In the case of the gun not being fired, the front end of the spring B being down,
and the lever C and sear D having remained in their normal positions, the extractor
is allowed to withdraw the cartridge slowly, but not eject it.
It is therefore shown that in a "bar lock" I make use of the rocking movement
of the mainspring to actuate the tumbler in the fore part, or the sear of the
extractor leg or tumbler.
The rocking of the mainspring may directly, or by the medium of a lever or rod,
or both, overtilt the fore end tumbler, or it may partially or wholly cock the said
tumbler.
At diagram 5 I indicate a spring rod a, having a spring piece bat its rear end,
which spring rod engages with the tumbler A or other movable part. On the
rebound or on the re-cocking of the hammer A, after firing, this spring rod a is
pressed forward through the knuckle joint and engages, on the opening of the gun,
with a sear D, which sear it withdraws from the tumbler in the fore part or from
the extractor leg or spring plunger, as illustrated by the diagram 6.
In some cases, and as shown by the diagram 7, I cause the spring rod a, to press
against the fore end tumbler e on the return of the hammer, which overtilts the said
tumbler e and leaves the tumbler e cocked, till on the opening of the gun the lower
end of the tumbler e coming against a projection in the action is tilted back and
forces back the extractor leg. Or the spring rod may tilt back the tumbler as
shown by the diagram 8 which has been previously tilted over in the closing of the
gun. Or the spring rod may partly or wholly cock the fore end tumbler as shown
by the diagram 9, the sear D being withdrawn on opening the gun. The spring
rod may be pressed forward as shown by the diagram 10, so that it presses a sear D
into bent, or retains the sear D in bent and the tumbler at cock, until the gun is
opened sufficiently far, when the sear D is actuated by the sliding rod a.
In place
of the sliding rod one or more levers as shown by the diagram 11 fulcrummed in the
action may be employed.
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
claim is :-
1. In ejecting mechanism for drop down sporting fire-arms, the utilization of the
rocking of the main spring, for actuating the ejecting mechanism in the fore part,
and substantially as set forth.
2. In ejecting mechanism for drop down sporting fire-arms, the sear in the fore
part in combination with the mechanism described for actuating the same by, and
simultaneously with, the falling of the hammer, and whereby the corresponding
cartridge is ejected on opening the gun whether the result be produced by the
movement of a spring rod or by the movement of the mainspring, all substantially
in and by the means hereinbefore described and illustrated with reference to the
accompanying drawings.
3. In ejecting mechanism for drop down sporting fire-arms and as applied to a
bar lock gun the actuating of the sear D in the fore part by means of the lever C
the latter being actuated by the rocking of the mainspring B and substantially as
hereinbefore described and illustrated with reference particularly to Figures 1, 2, 3
and 4 of the accompanying drawings.
4. In ejecting mechanism for drop down sporting fire-arms, the actuating of the
tumbler or sear in the fore part in and by a spring rod operated by the falling of
the hammer and substantially as and for the purposes described and illustrated with
reference to the diagrams Figures 5 to 11 of the accompanying drawings.
Dated this 10th day of October 1891.
