Improvements in Breech-loading Small-arms.
I HARRY GREENER of the firm of W. W. Greener of Prize Gun Works Saint
Mary's Square Birmingham in the County of Warwick, Gun Manufacturer do hereby
declare the nature of my said invention to be as follows:-
The object of my invention is improvements in breechloading fire-arms such for
instance as single or double drop down guns, rifles and pistols, being specially
applicable to guns where ejecting mechanism is used and is for the purpose of
avoiding the necessity of a second motion or drop in bringing the gun into cock or
bent, that is to say I accomplish the cocking of the gun without the second action
of the opening of the gun set forth in the Patent of my father William Wellington
Greener No. 2003 A.D. 1888 and this I accomplish in the following mnnner :-
In the case of my Fathers Patent, the tumbler, one or more, was made of one
solid piece or configuration whatever the particular shape might be according to the
design and formation of the gun. Now my tumbler, ono or more, is compound being
made up of two pieces connected together in such a manner that the fore arm which
comes in contact with the cocking swivel is free to move while the back or striking
end of the tumbler is fixed and held cocked by the seear. The two parts are so
connected or pivotted together, that in cocking the gun they both move substantially
together but in returning to their normal or uncorked position the supplemental or
forearm of the tumbler is free to move alone. It is also very important that the
forearm should be so attached or pivotted to the main portion of the tumbler that
the extremity of the forearm will be drawn slightly backwards in its return movement
and this 1 effect by placing its supplemental pivot or connection somewhat above
the main pivot or in front thereof or other position producing the same effect.
A shoulder or stop is formed between the two parts of the tumbler to make them
lift together when cocking the gun but they act separately in igniting the cartridge
and in ejecting the empty cartridge. By halving or notching the two parts of
the tumbler together the main spring acts upon both, that is to say when the
tumbler has been lifted sufficient to be secured by the seear the parts are so
arranged that the point of the loose forearm immediately afterwards passes below
the cocking swivel the main spring sending it down with a sufficient jerk to eject
the cartridge case while the striking or main portion of the tumbler remains cocked
upon the seear. The gun may now be closed without a second action.
Now immediately the gun is fired the altered position of the main portion of the
tumbler carries the loose forearm portion slightly forward so as to again bring it over
the cocking swivel so that it is ready to repeat the like effect in being recocked.
Instead of operating the bottom action bolt by means of a pin pressed down by
the barrels in closing I prolong the said bolt through the body to the front lump
which is formed with solid sides to carry the bolt the cocking swivel being led into
the lump quite flush or I may do it with the pin if I choose.

page_text: performed to be particularly described and ascertained in and by the following
statement:-
The object of my invention is improvements in breech loading small arms such for
instance as single or double drop down guns rifles and pistols, being specially applicable
to guns where ejecting mechanism is used and is for the purpose of avoiding the
necessity of a second motion or drop in bringing the gun into cock or bent that is
to say I accomplish the cocking of the gun without the second action of the opening
of the gun set forth in the Patent of my father William Wellington Greener
No. 2003 A.D. 1881 and this accomplish in the following manner.
In the case of my Fathers Patent the tumbler one or more, was made of one solid
piece or configuration whatever the particular shape might be according to the design
and formation of the gun.
Now my tumbler, one or more is compound being made up of two pieces connected
together in such a manner that the forearm which comes in contact with the cocking
swivel is free to move while the back or striking end of the tumbler is fixed and
held cocked by the seear. The two parts are so connected or pivoted together that
in cocking the gun they both move substantially together; but in returning to their
normal or uncocked position the supplemental or forearm of the tumbler is free to
move alone.
It is also very important that the forearm should be so attached or pivotted to the
main portion of the tumbler that the extremity of the forearm will be drawn slightly
backwards in its return movement and this I effect by placing its supplemental pivot
or connection somewhat above the main pivot or in front thereof or other position
producing the same effect. A shoulder or stop is formed between the two parts of
the tumbler to make then lift together when cocking the gun but they act separately
in igniting the cartridge and in ejecting the empty cartridge.
By halving or notching the two parts of the tumbler together the main spring acts
upon both, that is to say when the tumbler has been lifted sufficient to be secured
by the seear the parts are so arranged that the point of the loose forearm immediately
afterwards passes, below the cocking swivel the main spring sending it down with a
sufficient jerk to eject the cartridge case while the striking or main portion of the
tumbler remains cocked upon the seear.
The gun may be now closed without a second action.
Now immediately the gun is fired the altered position of the main portion of the
tumbler carries the loose forearm portion slightly forward so as to again bring
it over the cocking swivel so that it is ready to repeat the like effect in being
recocked.
Instead of operating the bottom action holt by means of a pin pressed down by the
barrels in closing, I prolong the said bolt through the body to the front lump which
is formed with solid sides to carry the bolt; the cocking swivel being let into the
lump quite flush or I may do it with the pin if I choose.
in order that my invention may be clearly understood and more easily carried
into practice I have appended hereunto one double sized and one single sized sheet
of drawings upon which I have fully illustrated my improvements applied to a
similar gun as that set forth by my Father in the aforesaid Patent which will serve
to make its application to the other firearms quite easy.
Figure 1. is a section through the lock of the gun showing the interior mechanism
in elevation with the breech open and the tumblers cocked.
Figure 2 is a similar sectional elevation of Figure 1 but with the breech closed
and the tumblers down.
Figure 3 is a similar sectional elevation to Figure 1 with breech open and the
mechanism in position immediately before the ejection of the cartridge takes place.
Figure 4 is a section through the compound tumbler and other mechanism on
line 1-2 Figure 8.
Referring to the drawings again my compound tumbler A consists of two main
portions namely the forearm A' and the striking end A' which are connected
together by the extra pivot a³ the tumbler A being mounted upon the main pivot a¹

page_text: thus enabling the point a" of the forearm A¹ to move and come in contact with the
cocking swivel b while the back or striking end A² of the tumbler A is fixed and
held cocked by the seear E. In cocking the gun the two parts A¹ and A' of the
tumbler A move substantially together as the forearm A¹ when ready for cocking is
in the position as seen at Figure 2 that is with the shoulder A of forearm a abutting
against the shoulder a' of the back part A' of tumbler A which leaves the gap a
between the two parts but in ejecting the fired case as shown in Figure 1, the
supplemental or forearm A' of the tumbler is free to move alone from the said
shoulder a² on account of the before mentioned gap a³. It is necessary that the
forearm A¹ should be attached or pivotted to the main portion of the tumbler A in
such a manner that the extremity a of the forearm a' will be drawn slightly
backwards in its return movement and this I effect in the example shewn by placing
the supplemental pivot or connection a³ somewhat above the main pivot a* or in front
thereof or in any other position producing the same effect.
A shoulder or stop a is formed between the two parts A¹ and A' of the
tumbler A by which means they are lifted together as shewn by Figure 3-when the
cocking is being effected; but the forearm acts separately in striking the point d¹
of the ejecting lever Das shewn by Figure 1: and the striking end A² acts separately
in igniting the cartridge as shewn by Figure 2. By halving shouldering or otherwise
notching the forearm A¹ into the tumbler A- the main spring Fis made to act in turn
upon both the forearm A' and the striking end A² this may be effected by the end f¹
of the spring being provided with the notch as shewn in Figure 4 so that when
the forearm A¹ has been sufficiently lifted by the cocking swivel for striking part
of the tumbler A to be secured by the seear E the pivot a³ of the forearm is so
arranged that the point as of the loose forearm A¹ is released from the cocking
swivel and the main spring F sends it down with sufficient force to eject the
cartridge by causing it to strike the ejector D: the striking or main portion A
remaining cocked upon the seear E and the main spring F taking its hearing upon
the main portion of the striking end A³ of the tumbler A as shewn in Figure 1 from
which position the gun may be closed without a second action. The point of the
main spring will act with the same effect upon both parts without the notch.
Immediately the gun is fired the altered position of the striking part A* of the
tumbler A carries the loose forearm A portion slightly forward so as to again bring
the point a of it over the cocking swivel 6' as shewn in figure 2 so that it is ready to
repeat the like effect in being recocked.
My compound tumbler may be used in a gun in which instead of operating the
bottom action bolt-by means of a pin pressed down by the barrels in closing I may
prolong the said bolt through the body to the front lump which would be formed
with solid sides to carry the bolt: the cocking swivel 61 being let into the lump
quite flush.
As a precaution against the tumbler being dropped before the breech is closed I
make provision for locking the striking mechanism when deemed necessary.
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 :-
The improvements in breech loading small arms in which the tumbler A is divided
50 as to enable the forearm A¹ and the striking part A to act independently and
together substantially as and for the purpose herein set forth and as shewn upon the
drawings.
