Improvements in and relating to Rebound and. Ejecting Mechanism
for Break-down Guns.
I, GEORGE DUNMORE POTTER, a citizen of the United States of America,
residing at Wallace in the County of Shoshone, and State of Idaho, one of the
United States of America, 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 more especially to that class of breech loading shot guns
known as break-down hammerless guns; and one object of the invention is to
provide for the automatic. cocking of the hammers by dropping the barrels ;
another object is to provide a mechanism for automatically ejecting the fired shells
of the cartridges from either or both of the barrels that may have been fired; and
still another object is to provide for a slight retraction of the hammers' from the
shells after firing and before the gun is fully cocked by dropping the barrels.
The invention comprises a swinging, curved lever, actuated by the fore-end,
which acts upon a cocking rod extending from the hinge joint to the hammer,
and which in turn acts upon said hammer through a link attached to said hammer
and to the end of the main spring. The said lever is swung backward by the
action of the fore-end as the barrels are depressed, and forces said cocking rod
backward through its channel in the body of the frame, and said rod is connected
with a stirrup, which is attached at its upper end to the main spring and midway of
its length is pivoted to the hammer, so that said rod tips and depresses said stirrup
on its swinging fulcrums with a toggle motion, and simultaneously cocks the hammer
and compresses the main spring..
The ejector mechanism comprises a spring-actuated ejector hammer, pivoted in
the fore-end, and operating in connection with the extractor stem and conjointly
with the cocking mechanism, whereby when the barrels are depressed after firing,
the said. ejector hammer is caused to strike the end of said extractor stem and
suddenly expel the shell of the fired cartridge from the chamber of the barrel.
As will appear presently, the mechanism serves at all times partially to extract the
shells when the barrels are dropped, independently of the ejector mechanism which
acts only after the gun has been-fired.
In the accompanying drawings.illustrating my invention, in the several figures
of which like parts are similarly designated-
Figure 1 is a vertical longitudinal section of the mechanism of the right hand
barrel of a breech-loading, hammerless ejector shot gun comprising my invention,
with the parts in position after firing and before the barrels are dropped.
Figure 2 is a similar view to Figure 1, with the barrels dropped; hammer at full
cock and extractor projected from the breech.
Figure 3 is a view similar to Figure 1, with the parts in position to fire, the
hammer being cocked.
Figure 4 is a vertical longitudinal section through the center of a portion of the
fore-end frame showing the ejector hammer and spring in their normal retracted
position.

Figure 15 is a perspective view of a modified form of stirrup used with the
hammer of Figure 14.
It is obvious that Figures 1, 2 and 11 are not true sectional views, and they are
purposely so made in order to bring into sight as many of the parts as possible.
a is a part of the stock, the standing breech or break-off, c the tang, d the
body of frame, e the barrel, and a portion of the fore-end, all as usual, excepting
as hereinafter described.
The parts being duplicated in a double-barrel gun, the following description of
the mechanism of the right hand barrel will be understood as applying to both.
Within a recess a' in the rear of the standing breech of the gun, is pivoted
the hammer g, which has pivoted to it and carries with it, the stirrup h, which is
attached also to the main spring i. The main spring has its lower forward end ¹
stepped in a block on the side plate presently described.
A cocking rod passes through an oblique channel.jl in the body d, and extends
from the knuckle at the front end of body d to and connecting with the
stirrup h.
The stirrup his hung by a pivot h at its upper end, in the forked and curved
end 3, Figure 1, of the main spring i, in a manner similar to that employed in
ordinary gun locks, and, as shown in Figures 1, 2, 3, 10, 11 and 12, has a laterally
extending pin 2 near its middle which enters a hole in the trunk of the hammer g.
The lower end of said stirrup h, which is of cylindrical form, passes down through
a recess in the side of the squared end j³ of the cocking rod j. As shown in
Figures 14 and 15, the hammer may be provided with the pivot pin 2, and the
stirrup be made with a hole to engage such pivot pin.
It will be observed that the upper end of the stirrup is held by the main
spring in a nearly constant position longitudinally of the gun, but is free to rise
and fall with the main spring. Also, that its other fulcrum 2 revolves with the
hammer on the center g' of the hammer.
The cocking rod has a rectilinear motion in its channel, and the same being
imparted to the lower end of stirrup at 2, produces in said stirrup a toggle
motion in consequence of its swinging fulcrums, by which the hammer is forced
back to full cock and the main spring is compressed.
A sear k, pivoted to the side plate engages with the bents of the hammer
as usual, and also engages and supports, on a laterally extending stud k², the rear
end of the main spring.
m is a semi-circular cocking lever having a cylindrical head m¹, journaled in a
shallow concave bearing n on the upper side of a hinge-pin n. This cocking
lever has on its forward side, about midway of its length, a triangular projection m²,
with a notch m³ on its upper side, and said lever m swings in a groove m³ in the
front end of body d, and a groove n² in the hinge-pin n. The combined bearing
formed by the concave depressions n in the top side of hinge-pin ³, and the
bearing in the end of the body d, amounting to more than a half circle, serves to
hold the lever m in position to be swung back and forth.
A vertical slot in the rear end of the fore-end f, the upper boundary of which
slot being a right line which, if extended, would be produced in the center of
the head m of the lever m, receives, when the fore-end is attached the projec
tion m² on the front side of the lever m; and the upper surface of said projection m

page_text: is also on a line projected from the center of the head m¹ parallel with the slot f¹,
as above.
The lower end m of the lever m swings under the hinge-pin n', and bears
against the end of cocking rod j.
When the barrels are depressed, in the act of opening the gun, the fore-end,
at bearing down on the projection with a rotary and inclined plane motion,
causes said lever to swing downward and backward, and its lower end m thereby
coming in contact with the other end of the cocking rod; forces the latter back
against the link and hammer g, thereby cocking the said hammer and compressing
the main spring.
Owing to the bearing n of said lever being eccentric to the axis on which the
barrels turn, the projection m² of said lever is withdrawn rearwardly as the lever
swings back, thereby releasing the ejector hammer, as hereinafter more fully
explained.
An ejector hammer o, (shown in detail Figure 4) is pivoted upon the pin o¹ in
the fore-end f slightly forward of the rear end of said fore-end and above the center
of same, presenting its lower laterally extended end o in front of the slot. The
upper end of said hammer, in its normal position, lies immediately under the forward
end of the extractor stem p which is in a recess in the underside of the barrets e.
The end o constitutes a hook or trip which projects rearwardly and downwardly
from the pivot o' of said hammer, and the forward lower end of said hammer has a
flat surface o, Figure 6. A forward projection o³ on said hammer terminates in a
rounded shoulder of. A spring attached to the fore-end has its free end in
contact with the flattened lower end of the ejector hammer, under the pivot o¹,
and normally tends to retract and hold retracted the said ejector hammer when the
gun is closed, and when the barrels are dropped, the projection or rounded
shoulder of of said ejector hammer is forced downward upon said spring and putting
it under tension, causes said spring to act forcibly upon the said hammer to revolve
it backwardly against the extractor stem, when its trip is released from the
projection m² of the lever m.
It will be apparent that, when the curved lever m is thrown forward and upward
by the fall of the hammer on the rod j, the projection m² on said lever will swing
under and into contact with the trip o2 of the ejector hammer o.
An extractor posts of the usual type used in breech loading shot guns, with the
exception that it has a cylindrical head s¹ for a purpose which will presently
appear, projects upward from the knuckle of the body d into a recess in the under
side of the barrels, where it connects with the stem p of the extractor pl. The
extractor and its stem p are split vertically through the entire length of the stem
as is usual in ejector guns. Near the forward end of the stem pa recess p² is
formed on the inner side of each half of such ejector stem, thereby forming a
mortice when the two halves are brought together, into which mortice the
cylindrical head of the extractor post s extends. This mortice is slightly longer
than the diameter of said head, thereby admitting of play between the extractor
post and stem backward and forward.
Starting with the gun in position after firing, that is, with the hammer down but
slightly retracted, the cocking rod thrown forward, the cocking lever m thrown
forward with the notch m³ in the projection m² in connection with the trip o² of
ejector hammer o, and the said ejector hammer o and its spring r in their normal or
rebound position, as all of said parts appear in full lines in Figure 1, the operation
is as follows:-
When the barrels are depressed, the slot 1 in the fore-end f, acting upon the
projection m² of the lever m with a rotary and inclined plane motion, swings said
lever m downward and backward, and the curved end m of said lever bearing
against the end of the cocking rod j, forces the latter backward through its channel
in the body d, and the rear end of said rod being in engagement with the lower
end of the stirrup h, swings the lower end of said stirrup backward on its fulcrum h
at the end of the main spring i, and the hammer ġ by virtue of the pivotal

page_text: connection therewith of said stirrup at a point between the said fulcrum h¹ and the
lower end of said stirrup which is connected with the end 3 of the cocking rod j, is
carried backward until it is canght and held by the engagement of the sear k in
the full bent of said hammer. And by the same movement of said parts,the
stirrup is carried downward, thereby compressing the main spring i
Concurrently with the above described movements, the projection m' is withdrawn
gradually through the slot f. in, the fore-end, and its notch m³ acting upon. the
trip o² of the ejector hammer o, raises, said trip out of said notch, thereby depressing
the forward projection of and through it the spring r, until the projection m² of the
lever m comes flush with the inside of the fore-end, when the trip is released, and.
the hammer,, impelled by thę spring flies upward. and backward, striking the end
of the extractor stem and ejecting, the partly.extracted shell. The momentum
of the hammer carries it beyond its normal, position, and, as it passes that position,
the extreme end of the spring r strikes against the flat lower end of the hammer o
and said spring is thereby arrested. As soon as the momentam of said hammer is
expended by its blow on the extractor stem p, the pressure of the end of spring r
on the flat end of hammer o, causes, the, latter to rebound to its normal position.and
there holds it until again acted upon by the projection m², as shown in Figure 3.
Jp the retracted or rebound position of the ejector hammer, which I call its
normal position, it is out of the way of the extractor stem p which is, moved
backwardly and forwardly by the posts. on the end of the body d, in,the usual
manner.
It will be observed, however, that, in the positive movement here referred to, the
post s bears against the rear shoulder, of the mortice pin,the extractor stein as the
barrels are depressed, leaving, a space between the forward side. of post and
the forward shoulder. of, mortice. When the ejector hammer strikes the end of
stem p, as above described, the stem is driven backward the length of this space,
or until the forward side of posts.and the. forward.shoulder of mortice p² are in
contact.
The position of the parts after dropping the barrels and with the same depressed,
is shown in Figure 2, in which the hammer g is at.full. cock, the cocking rod) is at
the rear limit of its travel where, it is held in contact with the stirrup h, and antil
the gun is fired, and the cocking lever m is swung back with its front projection. m²
Hush with the inside of fore-end, in which position it also remains when the gun is
closed (see Figure 3) and until the hammer falls and forces the rod j and lever m
forward. The retention of the lever m in this position is accomplished by causing
its end m to bind slightly ou the underside of the hinge-pin n when said lever is
swung back to its extreme liuit.
It will be apparent now by reference to Figures 1, 2 and 3, that, until the gun is
fired and the hammer falls forcing the rod j and through it the lever m forward,
the ejector mechanism will not be acted upon when the gun is opened and closed,
and, therefore, that only the partial and positive extraction of the shell will occur.
This extraction, as above explained is accomplished by the extractor post in the
usual manner, except that the stem p, instead of being retracted by the standing
breech alone, acting upon the extractor p!, is primarily and principally retracted
by the posts, and thereafter.the. retraction is completed by the action of..the
standing breech, upon closing the gun.
The gun having been cocked, and closed, as in Figure 3, the operation of, the
several parts upon firing the gun is,as follows:-
It will be observed that, owing to the constant tension of the main spring i upon
the centers and 2 of the stirrup h, and the center g' of hammer g, the said centers
tend to align themselves between the end 3 of the main spring and the other
extreme center g', and that any shifting of the end of the spring i, will result in a
change of inclination of the line of these centers. Also, that the position of the
end of the spring i, depends upon the inclination of the base of support of the
lower limb of said spring i, such base of support being the stud k² of the sear, and,
that the angle of inclination of said base of support is altered when the trigger- is

page_text: pulled and the rear end of the sear (upon the stud of which the spring rests) is
thereby raised, and the elevation of the rear end of the spring so effected throws
forward the end of the spring i. Now, as the free center of the toggle formed
by the aforesaid centers is pivoted to the trunk of the hammer g, it is evident that
the alignment of the center h² with the end of the spring i when thrown forward,
will result in swinging the laminer forward, as shown in dotted lines, Figure 1. Upon
releasing the trigger, the sear k and spring i fall back to the position shown in full
lines, Figure 1, and the centers 1, 2 and 9', in aliguing themselves with the changed
position of the end of the spring i, cause the hammer g to swing back into the
position shown in full lines, Figure 1, and away from the plunger 2. This
operation may be understood best by confining the attention to the movements
indicated by full and. dotted lines, Figure 1, of the hammer g, spring link and
sear k, and by observing that the slight retraction of the hammer is effected by the
alteration of the angle of inclination of the base of support upon which the
spring rests, when the trigger is pulled, thereby elevating the rear end of
the sear k. As a matter of fact, the hammer would be carried forward into contact
with the plunger 2 by the momentum of its fall independently of the position of
the end of the spring i, but the operation of retraction above described takes place
after the momentum of the hammer has been expended on the plunger, and the
change of position of the end of the spring i and accompanying shifting of the
alignment of centers and 2, caused by the pull and release of the trigger, is
designed merely to compensate the loss of effective thrust of the cocking-rod by
the retraction or falling away of the hammer g. Upon pulling the trigger. (not
shown) the rear end of the sear k is raised and its front end is disengaged from the
bent of the hammer g, thereby releasing the said hammer; and the main spring i
resting upon the lateral projection k² of the sear k, is also raised and its forward upper
cnd is thrown slightly forward of the vertical center of the hammer pin g¹. As
the hammer falls, this position of the main spring establishes a new and forwardly
inclined alignment of the centers and 2 with center g¹ tending to carry the
hammer correspondingly forward, thereby bringing the plunger in contact with the
primer of the cartridge when the several centers h² and g align in a dead center,
as shown in dotted lines, Figure 1. Upon releasing the trigger, the sear, main
spring and hammer fall back to the position shown in full lines, Figure 1, out of
contact with the plunger and with the hanımer held by the engagement of the sear k
in the half bent of the hammer.
It will be observed, in this connection, that the main spring serves, also, as a sear
spring by which the sear is forced into the bent and held until the trigger is
pulled. This is accomplished by making the lower limb of the main spring some-
what longer than its upper limb; and the degree of pressure upon the sear may
be made greater or less, according to the length of the lower limb.
I am aware that rebounding hammers are in use on certain hammerless guns, but,
so far as I know, the rebound of the hammer is obtained at the sacrifice of a
portion of the available throw of the cocking mechanism. The construction of my
gun is especially designed to avoid this loss of power, and it will be seen by
reference to the illustrations before and after firing, that the cocking rod remains
in constant contact with the stirrup h. By this construction, I conserve the full
effective scope of the cocking rod for the purpose of cocking the hammer.
A screw v, Figures 5 and 7, enters the front end of the body at the knuckle and
bears against a notch v¹ in the upper forward side of the hinge-pin n¹. The object
of this screw is to turn the hinge-pin over after the levers m have been placed in
the shallow bearings on the upper side of the hinge-piu, and to carry the upper
end m of said levers into the bearings completed by the concavity in the end of the
body d. The screw also serves to hold the hinge-pin in position, and to take up
any wear in the bearings.
I have described the hammer, main spring, stirrup and sear, as if arranged fixedly
in the frame, but, as indicated in Figures 12 and 13, these parts may be mounted

page_text: upon the detachable side plate k', and the bridle & connected with said side plate, so
as to render them readily removable and accessible.
is the main screw.
I have thus described, as already indicated, the best mole in which I have
contemplated applying the principle of my invention, but it is to be understood that
the details of construction are susceptible of variation within the claims of invention
