HERBERT JOHN HADDAN, of the Firm of Herbert and Company, Solicitors of
Patents, of 67, Strand, in the City of Westminster, Civil Engineer, "IMPROVE
MENTS IN BREECH LOADING GUNS, AND GUN LOCKS," a communication to me
from abroad by John P. Burkhard, and Frank Novotuy both of St. Paul, Minnesota,
United States of America,
This invention relates to an improvement in Breech Loading Guns, the object of
the same being first, to provide improved means for automatically cocking the 1
hammers when the barrels are tilted up at the breech to receive the cartridges.
A further object is to provide means for automatically cocking the hammers and
locking them in a cocked position, by simply tilting the barrels up at the breech to
receive the cartridges.
A further object is to provide simple means for unlocking the hammers when it 1
is desired to discharge the piece.
Further to provide simple and compact locks, composed of few parts, all of
which are secured to the side plates of the gun and adapted to be removed there-
with.
Further to provide safety mechanism for preventing the premature explosion of
the gun in case the sear should break, or become accidentally disengaged from the
hammer.
Further to provide automatic indicators so situated as to enable the gunner to
ascertain instantly whether the right or left or both hammers are cocked.
A further object is to provide means for removably securing the barrels to the
stock, and with these ends in view the invention consists in the parts and
combinations of parts as will be more fully described and pointed out in the
claims.

the barrels. Fig 16 is a perspective view of the side plate showing the combined
sear and main spring and the mechanism for holding the said combined spring in
a depressed position. Fig 17 is a view of one of the side plates showing a
modified form of safety mechanism, and Fig 18 is a detached view of the sear.
A represents the stock, B the active body and C the barrels, the latter being
pivotally secured to the active body in a manner to be hereinafter described. The
stock A is provided at its forward end with recesses, and slots for the active body
of the gun and for the side and the trigger plates, the main portion of the said
end however being undisturbed or left solid so as to afford a firm and solid bearing
for the parts attached thereto.

page_text: Each side plate D is of the ordinary shape and is provided on its inner face
with a concealed hammer a, the main spring b, the sear c, and the safety mechanism
which will be hereinafter referred to. The hammer a is provided with one or more
sear notches with which the end of the sear engages and when in a depressed
position rests up against the inward projection e formed integral with the side
plate D.
The V shaped spring b is secured to the side plate in any desired manner and
acts directly on the hammer and sear, thereby dispensing with the services of an
extra spring for each lock. The sear c is provided at its rear end with an inwardly
projecting finger d, the outer end of which latter rests over one of the triggers g
secured to the trigger plate.
f is a finger formed integral with the hammer and adapted to register with the
notch in the indicator F.
The indicators (one behind each barrel, and operated independently by the
hammers) are pins which pass vertically through the portion of the active body
which forms the breech lock. The finger f of the hammer registers with the slot h
in the indicator and moves the said indicator simultaneously with the hammer.
When the hammer is moved backward to a cocked position, the indicator is also
moved upward until the upper end thereof rests above the breech block, and when
the hammer falls the indicator pin also falls with it. By this means the gunner is
able to tell at a glance if either or both hammers are cocked. These indicators
besides performing the function above described also serve to hold the firing pins
in place and prevent their accidental displacement. The firing pins G pass
horizontally through the breech block, one behind each barrel, and each is provided
about midway its length with a cut away portion for the passage of the
indicators F. These firing pins G are free to move a slight distance, and the rear
ends thereof project through the breech block, and terminate in front of the
hammer. Each hammer a is also provided with a curved lateral projection i with
which the rear ends of the cocking bars H engage. These cocking bars are
L shaped and pass longitudinally through the active body from the point where
the barrels are pivoted thereto to the hammers a on the face plates. The rear
portions of these cocking bars are each provided on its upper face with a curved
cut away portion in which the curved lateral projection of the hammers a rest.
The front end of each of these cocking bars is provided with an inwardly projecting
arm j the ends of which latter meet in the vertical center of the active body.
From the foregoing it will be seen that by exerting a pulling force on the cocking
bars, the hammers are thrown backward to a full cock, and held in such position
by the sears c.
The cocking bars are moved longitudinally by tilting the barrels and after the
hammers are cocked the cocking bars can be moved without interfering with the
hammers. The precise manner of operating the cocking bars will be described
further on.
To prevent a premature explosion in case the sear should be accidentally
disengaged from the hammer I have provided an independent safety attachment
adapted to engage the spring b and hold it in a depressed position. This safety
attachment is also secured to the side faces of the lock and consists of a dog k and
the operating lever k¹ both of which are set into the inner face of the side plates so
as not to interfere with the free movement of the other parts. The movement of
the operating lever is controlled by the spring / which can be formed integral
with or separated from the said lever as desired. The rear end of the operating
lever k terminates in an inwardly projecting finger which latter rests in close
proximity to the finger d on the sear c. The opposite end of the lever ¹ rests in
an open slot in one end of the dog k, while the free end of the said dog is adapted
to rest over a lateral projection m on the spring b.
The pendant arm of the dog k rests in front of the projection or abutment m on
the spring b and as the said spring b is depressed during the cocking operation, the
said dog is moved to enable the projection m to pass downward. As soon as it passes

page_text: the lower end of the pendant arm of the dog it (the dog) swings around by the
action of the spring 2 and bars the upward movement of the spring b. Thus it
will be seen that if the end of the sear should by any accident whatever become
disengaged from the hammer, the spring would still be under control and be
inoperative until released from the dog. But when it is desired to discharge the
piece, the trigger acts alike on the lever k¹ and the sear simultaneously removes all
obstacles tending to hold the hammer back.
These side plates with the parts before described are secured on opposite sides
of the gun by the single screw n which passes through both side plates and the
intervening stock.
When it is desired to clean the lock it is simply necessary to remove the screw n
with an ordinary screw driver and take off the plates with the operative parts
of the lock attached thereto, without disarranging any other parts, it making no
difference whether the hammers are cocked or not. When this is done the entire
operative parts of the lock can be easily and quickly detached from the plates for
cleaning by use of the single screw driver at hand and as readily put together
again. Again the particular construction of lock herein described permits the
hammer to be snapped without in anywise endangering the gun.
The front end of the active body of the gun is curved in the arc of a circle,
and forms the bearing on which the barrels turn.
The active body is also provided with two or more openings into which the
lugs pp on the under side of the barrels rest, and in which they are secured by
the wedge shaped holding bolts J J. The barrels are pivoted horizontally to the
active body of the gun, and consequently swing in a vertical plane in opening and
closing, the hooked lugs on the underside of the barrels being adapted to register
with the openings in the active body. The openings or slots in the lugs on the
underside of the barrels are made wedge shaped and the breech bolt J³, and the
lower bolts J J¹ which enter said notches are also wedge shaped for a purpose to
be hereinafter described.
The bolts J and J which enter the hooked lugs p' p³ are made in separate
pieces of the form shown, and move and rest in recesses formed in the active body
of the gun.
The rear end of the lower bolts J J is provided with an upwardly
extending arm q, the upper end of which latter rests in an open slot r formed in
the downward extensions of the upper bolt J. The rear end of the upper bolt J²
is connected by the compensating link t to the tumbler K, which latter in turn is
connected to the top lever L. The movement of this tumbler K is controlled by
the spring M, the constant tendency of which is to force the bolts J J and J²
outward into the notches formed in the lugs p, p¹, p², of the gun barrels. When
the lever L is turned in the proper direction the bolts J J¹ and J2 are withdrawn
from the notches in the catches p p¹ p² and the barrels are allowed to tilt.
The compensating link t is made in two parts one of which is provided with a
female screw threaded socket and the other with a screw, which latter screws into
the female screw threaded socket. By simply unscrewing the parts this link can
be lengthened to compensate for any wear of the wedge shaped bolts, or of the
wedge shaped notches formed in the depending lugs p p¹ on the underside of the
gun barrel, or the wedge shaped notch on the breech lug p². The movement of
the top lever L also performs another important function, viz. automatically locking
the triggers against movement. To tilt the barrels it is necessary to move the top
lever L, and when the said top lever is moved a sufficient distance to withdraw
the bolts J JJ, the automatic lock or safety mechanism is also brought into
operation. This safety mechanism consists of a long rod N secured to the under-
side of the top plate of the active body, the front end of which rests in close
proximity to the tumbler K. The central portion thereof is provided on its upper
and lower faces with cams which latter regulate the movement of the vertically
movable bar w. This bar is guided by depending arms on the top plate of the
active body and is provided with an opening through which the rod N passes.
The rod N is also provided back of the cams v with notches (preferably two) into

page_text: which the front end of the spring. O rests. The rod N is also connected to the
thumb piece P, which latter slides on the upper surface of the top plate of the
active body. This thumb piece P covers a mark or plate set into the active body
which can have the word "safe" engraved thereon or not as desired, at any event
denoting that when the mark or plate is covered by the piece P the triggers are
unlocked. As before stated the front end of the rod N rests in close proximity to
the tumbler K. This rod N is free to move longitudinally, and as the tumbler K
is turned it strikes the end of the rod N and moves it rearwardly and uncovers the
mark or sign which indicates whether the triggers are locked or not. As the
rod N is moved, the cams v passing through the restricted hole in the vertically
movable bar w, elevates or depresses the said bar, the movement of the said rod
however being dependent on the direction of movement of the rod N. When the
top lever L is turned to withdraw the bolts, the rod N is moved rearward and the
bar w depressed so as to bear directly on the triggers g and prevent them from
performing their functions. When the rod N reaches the end of its back stroke,
the end of the spring M falls into a notch formed in the rod N and holds the said
rod against accidental movement in either direction. When the parts are all
adjusted and it is desired to discharge a cartridge, it is simply necessary to move
the thumb piece P forward as far as it will go. This forward movement of the
rod N elevates the vertically movable bar w and leaves the triggers free to be
moved. If it is desired to lock the gun after one barrel has been discharged, it is
simply necessary to move the thumb piece backward, which as before stated
depresses the bar w, and locks the triggers.
The gun barrels are pivotally secured to the front end of the active body of the
gun, between it and the movable portion Q of the stock A. The front face or edge
of the hooked catch or lug p is curved as shown at y, against which curved portion
the arm of the cocking bars H rest and on which they move. The half circular
notch a situated immediately below the curved portion y bears against the portion
of the active body which forms the axis on which the barrels C move and
consequently when the barrel is tilted, the curved portion y is moved in the arc of
a circle away from the active body and draws along with it the cocking bars H.
As soon as the required distance is traversed, the sears engage the hammers and
hold them back in cocked position. When the barrels are righted the cocking bars
are also moved inward in position to engage the hammers for the next cocking.
The fore part G of the stock A is secured to the gun barrels by the spring
actuated catch T which in outward appearance resembles an ordinary catch. The
gun barrels are also provided with a depending lug b¹ having a notch on its rear
face with which the spring actuated catch engages.
The lug b¹ projects downward into a close fitting socket formed in the portion Q
of the stock, and the hooked catch c¹ engages with the notch therein and holds it
firmly in place without danger of liability of displacement. The catch c¹ is operated
by the lever and spring d' the latter tending to hold the lever d¹ in a closed
position. This construction of parts enables the fore part of the stock to be secured
in position by simply placing the rear end t thereof against the fore end of the
active body and pressing the parts together. During the operation the lever d¹
need not be touched and remains stationary it being called into use only when
desired to take the gun apart.
When it is desired to remove the barrels from the stock, it is simply necessary to
remove the fore part Q of the stock from the barrels. The top lever L is then
turned which releases the barrels from the active body and allows them to be
removed for any purpose whatever.
When it is desired to load the gun, the top lever L is turned which allows the
barrels to tilt, exposing the breech. This movement of the barrels cocks the
hammers and throws up the indicators and the movement of the top lever locks
the triggers and prevents any accidental explosion of a cartridge.
The cartridges are then inserted in position and the breech closed by righting the
barrels.

page_text: When the gun is in this position it is simply impossible for an accidental
explosion to take place and before it can be fired, the thumb piece P has to be
moved so as to cover the safety mark. This gun in outward appearance resembles
very closely the guns now commonly used by sportsmen, but in internal structure
it differs materially. In the first place the front end of the stock to which the
active body is secured is nearly solid, while those in guns now used is necessarily
cut up to accommodate the complicated mechanism employed thereon. By means
of my cocking bars, and the manner of connecting them to the barrels an immense
leverage is obtained, and a correspondingly striking force given to the hammer.
This invention is simple in construction, is of comparatively few parts, can be
entirely taken apart and put together with the aid of an ordinary screw driver, and
all the operative parts are of comparatively light weight and compact build and
singularly frictionless in their workings.
In Fig 17 and 18 I have shown a modified form of safety mechanism and sear.
In the safety mechanism before described, the pivoted dog K is held in position
over the projection m of the main spring, by the small spring which latter acted
through the intervention of the lever k'. In this modified form the small supple-
mentary spring is dispensed with and the movements of the pivoted dog
controlled by the main spring b.
In this instance the sear arm d is provided with a flange d' that projects over
the arm of the lever k¹, and hence when the rear end of the sear is depressed,
the rear end of the lever k¹ will also be depressed and retain the locking dog in
position for engaging the projection m of the main spring when the hammer is
cocked. By causing the rear end of the sear to engage the arm of the lever k¹
the main spring b performs the double function of operating the sear and retaining
it in engagement with the hammer and also of retaining the pivoted dog in proper
position to engage the main spring and lock it against accidental action when the
hammer is cocked. The trigger when raised elevates the rear ends of the sear and
of the safety lever, thereby disengaging the dog from the main spring and leaving
the latter free to throw the hammer forward and also disengage the sear from its
sear notch in the hammer.
From the foregoing it will be observed that the safety attachment is extremely
simple in its construction and arrangements of its parts and adds but slight
expense to the cost of manufacture, and renders the operation of the lock absolutely
safe and reliable. When the hammer is retracted and cocked the safety dog will
automatically engage the main spring and retain it in its depressed position and
out of operation.
In this adjustment of parts the main spring is kept from throwing the hammer
forward even though the sear should become disengaged from the sear notch and
thereby rendered incapable of holding the hammer in its cocked position.
It is evident that numerous changes in the position and construction of the
several parts of the gun might be resorted to without departing from the spirit and
scope of this invention, and hence I would have it understood that I do not limit
myself to the exact construction shown and described but consider myself at
liberty to make such changes and alterations as fairly fall within the spirit and
scope of this invention.
