of London, Merchant, and Manufacturer, and Walter Fletcher, of the same
Place, Gunsmith, for an Invention of "AN IMPROVED CONSTRUCTION OF
SAFETY FASTENER WITH AUTOMATIC DOUBLE ACTION FOR THE STRIKERS,

"AN
HUGH ADAMS SILVER, of Sun Court, Cornhill, in the City of London, Merchant
and Manufacturer, and WALTER FLETCHER, of the same Place, Gunsmith.
IMPROVED CONSTRUCTION OF SAFETY FASTENER WITH AUTOMATIC DOUBLE ACTION
FOR THE STRIKERS, TUMBLERS, OR THE TRIGGERS OF SPORTING AND OTHER GUNS
(SINGLE AND DOUBLE)."
The object of this Invention is an improved construction of safety fastener with
automatic double action for the strikers, tumblers, or the triggers of sporting and
other guns (single and double).
Our Invention consists essentially of a lever of special construction and its
method of action for locking the striker, the tumbler, or hummer, in conjunction with
a pivotted or a fixed leg operated by the lever and locking the trigger or triggers,
both operations being effected under the action of a spring, when the hand of the
firer is removed from the "small" or fore part of the stock. Both the lever and
the leg are pivotted to the strap of the breech piece, and the leg, which is kinked,
works through a slot in the lever to compel it to move when the lever is moved,
this being done by the firer when he grips the small of the stock to take aim.
The foro end of the pivotted lever is formed with a claw or hook to engage in
a claw or hook on the front portion of the head of the striker or tumbler, and
the lower end of the pivotted leg is turned at right angles, or is shaped to bear
upon the top of the trigger to prevent any movement of it, except when the
opposite end of the claw lever is depressed by the hand of the firer.
The rear part of the pivotted lever is shaped to fit a recess in the breech strap, and
in its normal position its upper surface projects slightly above the strap, and becomes
compressed by the natural movement of the firer's hand. At all other times the
striker or tumbler lever or levers and the trigger or triggers are locked. If found
desirable, a small transverse bolt may be provided on the strap to lock the pivotted
lever, or it may slide forward on the strap for that
purpose.

Office on the 14th April 1881.
HUGH ADAMS SILVER, of Sun Court, Cornhill, in the City of London, Merchant
and Manufacturer, and WALTER FLETCHER, of the same Place, Gunsmith. AN
IMPROVED CONSTRUCTION OF SAFETY FASTENER WITH AUTOMATIC DOUBLE ACTION
FOR THE STRIKERS, TUMBLERS, OR THE TRIGGERS OF SPORTING AND OTHER GUNS
(SINGLE AND DOUBLE).
The object of this Invention is an improved construction of safety fastener with
automatic double action for the strikers, tumblers, or the triggers of sporting and
other guns (single and double).
Our Invention consists essentially of a lever of special construction and its
method of action for locking the striker, the tumbler, or hammer in conjunction with
a pivotted or fixed leg operated by the lever and locking the trigger or triggers,
both operations being effected under the action of a spring when the hand of the
firer is removed from the "small" or fore part of the stock. Both the lever and
the leg are pivotted to the strap of the breech piece, and the leg, which is kinked,
works through a slot in the lever to compel it to move when the lever is moved,
this being done by the firer when he grips the small of the stock to take aim.
The fore end of the pivotted lever is formed with a claw or hook to engage in a
claw or hook on the front portion of the head of the striker or tumbler, and the
lower end of the pivotted leg is turned at right angles, or is shaped to bear upon
the top of the trigger to prevent any movement of it, except when the outer end
of the claw lever is depressed by the hand of the firer.
The rear part of the pivotted lever is shaped to fit a recess in the breech strap,
and in its normal position its upper surface projects slightly above the strap, and
becomes compressed by the natural movement of the firer's hand. At all other
times the striker or tumbler and the trigger or triggers are locked. If found
desirable, a small transverse bolt may be provided on the strap to lock the pivotted
lever, or it may slide forward on the strap for that purpose, or may be locked to
place the automatic out of use for the time being.
The annexed Sheet of Drawing clearly represent our Invention.
Figures 1 and 2 are plan and side elevation of our Invention composed of
levers A, B. The lever A is pivotted to the strap C of the breech D of the arın, as
shown at Figure 3, and when in the normal position it, under the action of the
spring E, acts upon the kinked portion F of the lever B, and throws the end G over
and upon the trigger H to prevent the trigger being pulled by accident or other
causes.
The lever B is pivotted (suspended) from the strap C, and is moved backward
away froin or forward above and upon the trigger, according to the movement of
the lever A, when the end I is depressed by the hand of the firer or returned to the
position shown at Figure 3 under the action of the spring E. The lever A is
pivotted to a lug J arranged under the breech strap C, and at a tangent to the
pivot of the lever B in order to obtain the necessary motion for the duties they
have to perform.
The inner end K of the lever A is bent at right angles, or nearly so to its length,
so that it is located in the path of the striker or tumbler L, which. on being raised
to be set, lifts that end of the lever A and passes and becomos locked so to speak
behind the end A, as is shown at Figure 4, where the lever end K acts as a stop to
any accidental movement of the striker on the tumbler, should it become released
from any cause other than when desired.

page_text: Our Invention of the safety fastener with automatic double action for the striker,
tumbler, and trigger, of single barelled, sporting, and other guns, is further
illustrated at Figure 5 in side elevation and in Figure 6 which is a plan of the
under side of the levers A, B, and the breech strap C, the dotted linos in Figure 5
showing the position the two levers take when the end I is depressed, that its top
becomes level or nearly so with the upper surface of the breech strap C.
Figure 7 shows the lever A with the inner end spread outwards from each side,
that the right angled parts may act upon and hold the two strikers or tumblers of
a double barrelled, sporting, or other gun.
In these three last views we show the locking bolt M formed from apart of the
outer end I of the lever A. This bolt can be easily thrown outwards to lay partly
across the breech strap, and so prevent the end I being depressed; at other times it
is in line with and serves as part of the end I to be forced into the slot of the
breech strap C.
Other shapes or arrangements of bolts to lock the lever A may be used either as
bolts pivotted on the breech straps or as sliding bolts.
Having now described the nature of our said Invention, and in what manner
the same is to be performed, we declare that we claim,―
The safety fastener composed of lever A and lever B, Figures 1 and 2 of the
annexed Drawings, and acting in conjunction with other appliances for locking the
strikers, tumblers, and triggers of sporting and other guns (single and double), as
described and substantially as shown in Figures 3 and 4 of the annexed Drawings.
In witness whereof, we, the said Hugh Adams Silver and Walter Fletcher,
have hereunto set our hands and seals, this Fourteenth day of April, in the
year of our Lord One thousand eight hundred and eighty one.
