PROVISIONAL SPECIFICATION.
Improvements in the Extracting and Ejecting Mechanism of
Drop-down Sporting Guns and Rifles.
I, JAMES WILLIAM SMALLMAN, of 61, Chancery Lane, in the County of
Middlesex, Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to extracting and ejecting mechanism for drop-down
sporting guns and rifles of the kind described in the Specification to my Letters
Patent No. 9062, A.D. 1889, wherein the ejecting plunger is carried by the barrels ;
the non-firing or firing of the weapon determining whether the movement of the
plunger shall be gradual for extracting or sudden for ejecting. The invention is,
however, applicable to guns or rifles in which the ejector-sear engages with the
extractor-leg, or having the ejector-striker carried by the fore-end.
The objects of the present invention are, first, to utilize a long cocking lever for
keeping the ejector-sear out of bent until the gun or rifle is fired; and, secondly,
to enable an extractor-post carried by the fore-end to begin the compression of the
extracting and ejecting springs by forcing back the extractor at the commencement
of the closing of the gun or rifle.
According to the first part of my invention, I pivot in the fore-end (in respect
of each barrel) a sear-actuating lever, one arm of which is in contact with the
ejector-sear and the other with the cocking lever when the tumbler is cocked. The
ejector-sear is furnished with a sear spring. The cocking lever may be jointed to,
or engage in a notch cut in, the tumbler.
At the
When the end of the sear-actuating lever is in contact with the cocking lever,
the sear is held, against the pressure of the sear-spring, out of bent. When the
gun or rifle is fired, the cocking lever turns on its pivot, releasing the scar-actuating
lever, thus allowing the sear-spring to force the sear into bent, and at the same time
to cause the sear-actuating lever to get into the path of the cocking lever.
termination of the opening movement, the sear is tripped in the usual manner.
While the gun is being closed, the scar-actuating lever slides against the extremity
of the cocking lever, and is thus forced into the position in which it holds the sear
out of bent. If the gun or rifle has not been fired, the sear is released gradually,
and gets into contact with the plunger or striker behind the bent, with the result
that it remains inoperative, the cartridges being extracted to the full distance in
the ordinary way.
In carrying out the second part of my invention, I cause the extractor-post to
engage with the action-body so that it cannot move with the lump to any appreciable
extent while the gun or rifle is being closed. That part of the slot in which the
fore-end iron works may be wider than that part of the slot wherein the lump is
fitted; the extractor-post taking a bearing against the shoulders at the junction of
the wider part of the slot with the narrower part.
The advantage of this construction is that there is no projection on the action to
interfere with putting the barrels on; the extractor being consequently allowed to
come out far enough to release the ejector-springs when the gun or rifle is taken
apart.

Improvements in the Extracting and Ejecting Mechanism of
Drop-down Sporting Guns and Rifles.
I, JAMES WILLIAM SMALLMAN, of 61, Chancery Lane, in the County of
Middlesex, Engineer, 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 extracting and ejecting mechanism for drop-down
sporting guns and rifles of the kind described in the Specification to my Letters
Patent No. 9062, A.D. 1889, wherein the ejecting plunger is carried by the barrels ;
the non-firing or firing of the weapon determining whether the movement of the
plunger shall be gradual for extracting or sudden for ejecting. The invention is,
however, applicable to guns or rifles in which the ejector-scar engages with the
extractor-leg, or having the ejector-striker carried by the fore-end.
The objects of the present invention arc, first, to utilize a long cocking lever
for keeping the ejector-sear out of bent until the gun or rifle is fired; and, secondly,
to enable an extractor-post carried by the fore-end to begin the compression of the
extracting and ejecting springs by forcing back the extractor at the commencement
of the closing of the gun or rifle.
In the accompanying drawings,
Fig. 1 represents in side elevation mechanism constructed in accordance with
my invention; the lock being cocked.
Fig. 2 is a similar view showing the parts in the position they occupy after the
firing of the gun or rifle.
Fig. 3 is a detached view of the right-hand sear-actuating lever.
Fig. 4 is a corresponding end elevation.
Fig. 5 is a separate view of one of the ejector-sears.
Fig. 6 is a plan of the same.
Fig. 7 illustrates the application of my invention to ejecting mechanism of a
different kind to that shown in the preceding figures; the parts being represented
in the position they occupy before the firing of the weapon.
Fig. 8 is a similar view; the parts being in the position they occupy after the
weapon has been fired.
Fig. 9 is a side elevation of one of the modified ejector-scars pertaining to this
mechanism.
Fig. 10 is a corresponding end elevation.
Figs. 11 and 12 are explanatory diagrams.
Fig. 13 is a view, partly in side elevation and partly in section, illustrating the
extractor-post and adjacent parts.
Fig. 14 is a section through the action-body showing the slot in which the
extractor-post and the lugs on the fore-end-iron fit.
Fig. 15 is a side elevation of the fore-end-iron and extractor-post.
Fig. 16 is a separate side elevation of the extractor-post.
Fig. 17 is a front elevation thereof.
According to the first part of my invention, I pivot in the fore-end (in respect
of each barrel) a sear-actuating lever A A'; the arm A of which is in contact with
the ejector-sear B or B¹, and the arm A¹ with the cocking lever C when the
tumbler D is cocked. The ejector-sear is furnished with an ordinary sear-spring,
which is omitted in the drawings. The cocking lever, instead of being made as
illustrated, may, if preferred, engage in a notch cut in the tumbler.
When the end of the arm A¹ of the sear-actuating lever A A' is in contact
with the cocking lever C (Figs. 1 and 7), the sear B or B' is held, against the
pressure of the sear-spring, out of bent. When the gun or rifle is fired, the cocking
lever C turns on its pivot C', releasing the sear-actuating lever A A¹, thus

page_text: allowing the sear-spring to force the sear B or B' into bent, and at the same time
to cause the sear-actuating lever A A¹ to get into the path of the cocking lever C.
The sear-actuating lever A A' may, however, be provided with an independent
spring. At the termination of the opening movement, the sear B or B' is tripped
in the usual manner. While the gun or rifle is being closed, the arm A¹ of the
sear-actuating lever A A¹ slides against the extremity of the cocking lever C;
the lever A A¹ being thus forced into the position in which it holds the sear B
or B' out of bent. If the gun or rifle has not been fired, the sear B or B¹ is released
gradually, and gets into contact with the plunger E or striker F behind the bent,
with the result that the said sear remains inoperative, the cartridges being extracted
to the full distance in the ordinary way. In Fig. 11, the sear B is represented as
having missed the bent in the plunger E, and in Fig. 12 as having failed to catch
in the notch in the extractor-leg G.
In carrying out the second part of my invention, I cause the extractor-post K to
engage with the action-body so that it can not move with the lump on the barrels
to any appreciable extent while the gun or rifle is being closed. The part H of
the slot H H (Fig. 14) is wider than the part H₁; wings
and on the
extractor-post K taking a bearing against shoulders, such as the shoulder H*, at
the junction of the wider part of the slot with the narrower part. k is a stop for
tripping the ejector-sear B. J is the fore-end-iron; J¹ being the right-hand lug.
L is part of the left-hand half of the split extractor.
The advantage of this construction is that there is no projection on the action-
body to interfere with putting the barrels on; the split extractor being consequently
allowed to come out far enough to release the ejector-springs carried by the barrels
when the gun or rifle is taken apart, thus dispensing with the catch usually
employed for holding back the split extractor.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I claim :-
:-
1. The improved extracting and ejecting mechanism for drop-down sporting
guns and rifles constructed and operating substantially as described.
2. In drop-down sporting guns and rifles, the employment of the cocking lever
for keeping the ejector-sear out of bent until the gun or rifle is fired, substantially
as described.
3. In a drop-down sporting gun or rifle, the combination, with the cocking lever,
of a sear-actuating lever, substantially as and for the purpose set forth.
4. In drop-down sporting guns and rifles, the employment of an extractor-post
carried by the fore-end and engaging with the slot in the action-body, substantially
as described, the same being adapted to force the extractor forward during the
opening movement and backward during the closing of the gun or rifle.
