We, HENRY PARSONS, of 2 Court Hanley Street, Birmingham, in the county of
Warwick, Gun Barrel Maker, and WILLIAM BOWN, of Summer Lane, Birmingham,
aforesaid, Manufacturer, do hereby declare the nature of this invention to be as
follows:
Our improvements relate to guns known as drop down snap double bolt guns.
The first part of our invention is that we construct a gun so as to make the cocking
of the hammers or locks automatic in the manner hereafter describod. The lump on
the barrels having an extension or roller on the end, enters the body of the action by
a slot in the face. In the body of the action in the slots so cut out we place a lever
working a centre pin, which centre pin is keyed on to the lever at a suitable distance,
the said centre pin passing through the body of the action and carrying a lifter or
lateral arm on each side for each hammer tumbler or lock. The lever may carry a
roller and come flush or extend over the face of the action. In the opening of the
gun the extension or roller on the lump being under and beyond the face of the
action, will raise the lever placed above and extended over the face so out of its
position as to accelerate the notion of the lateral arms on the centre pin, which
lateral arms passing under the hammers or tumblers come in contact with a projection
or portion of the hammers and lift them into the bent in the locks, which locks may
be of the usual kind or the hammers may be placed in the body itself.
We ensure the safety of the gun by blocking the fall of the hammer, such block
being actuated by the movement of the centre pin or arms.
The second part of our invention is to facilitate the opening of guns such as
herein before described, and all guns carrying a double or sliding bolt, and our
improvements are carried out in the following manner. When the lever of the gun
is moved and the bolt withdrawn out of the steel lump in the barrels we cause both
the bolt and lever to be held in that position by a block moving into the opening in
the steel lump and thus preventing the return of the bolt. The said block carries a
spring, or is moved by a spring, and hinged on a pin in the lump on the barrels ;
which block moves from the steel lump as the gun is closed.
The block may be made to be the spring itself.

We, HENRY PARSONS, of 2 Court Hanley Street, Birmingham, in the County of
Warwick, Gun barrel maker, and WILLIAM BOWN, of Summer Lane, Birmingham,
aforesaid, Manufacturer, 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 :-
Our invention relates mainly to improvements in that class of guns known as drop
down snap double bolt guns, and the invention comprises means whereby the cocking
of the hammers or locks of such guns is automatically effected and means whereby
the opening of such guns as well as other guns carrying a double or sliding bolt is
facilitated.
In order to enable our invention to be fully understood we will describe how it can
be carried into practice by reference to the accompanying drawing in which
Figure 1 represents a side elevation of the lock action and part of the barrels of a
gun constructed according to our invention the plate carrying one of the hammers
and mechanism connected therewith being removed.
Figure 2 is a detached elevation of the opposite plate carrying the other hammer
and mechanism connected therewith.
Figure 3 is a detached face view, and
Figure 4 is a detached edge view of the lever with pin or pivot and lifting arms
hereinafter described.
Figure 5 is a detached view of a device or snap for securing the fore end of the
gun to the barrels.
Similar letters in all the figures indicate similar parts.
For the purpose of rendering the cocking of the hammers or locks of drop down
snap double bolt guns automatic, we construct the lump a on the barrels with an
extension b, as shown in figure 1, (or a roller) which enters the body c of the action
through a slot cut in the face thereof. In the said slot we place a lever d formed or
fixed on a pin e, el at about the middle of the length of the said pin which passes
transversely through the body of the action and carries a lug or projection on the
part e thereof; the part e¹ of the pin is formed square and reduced in size and receives
a sleeve g carrying a lug or projection f similar to that on the part e of the pin. The
sleeve g is secured by a screw passed into the part e¹ of the pin; lifting arms i
and are pivotted to the lugs and as clearly shown in figures 3 and 4.
The object in making the lever, pin and lugs in two pieces in the manner just
described is to enable them to be easily fitted in the body c of the action, as will be
well understood without further explanation.
Each of the lifting arms i and engages into or presses on a hammer ; at or under
a projection or shoulder k near the centre thereof.
a is a spring for operating the lever d.-The lever d can, if required, be provided
with a roller to facilitate the movement of the part 6 over the same.
b

page_text: By this construction, the barrels being in their closed position when the extension 6
(or roller) on the lump a, will be below and extend within the face of the action, if
the barrels be moved down in the usual way to open the gun the extension b will force
back the lever d.
By this action the lifting arms i, will be caused to move back the hammers; so
as to engage the bents k thereof with the sears 7 which may be of the usual kind.
The hammers can obviously, if required, be placed within the body c of the action
instead of in the position shown in the drawing.
In order to ensure the safety of the gun we provide for each hammer a safety block
or catch m, figures 1 and 2, pivotted at n and adapted to catch into a recess o in the
hammer and thereby retain the same when moved into its cocked position as shown.
The block or catch m is provided with a downward angular projection p against which
and against a projection on the sear 1, the trigger bears when pulled to fire the
gun thereby releasing the hammer from both the block or catch m and sear 1.-Should
however the sear become accidentally disengaged through a shock or otherwise the
hammer would be still retained by the block or catch m.
In order to secure the fore end to the barrels we provide a device or snap shown in
figure 5 consisting of a spring bolts, pivotted in a plate t let into the fore end the
said bolt being adapted to easily take into a notch in a lump on the barrels and be
thereby securely retained in position.
The said bolt will however pass out of the notch in the lump if a moderate amount
of force be used to pull the fore end away from the barrels.
In order to facilitate the opening of guns such as those herein described and other
guns the barrels of which are opened and closed by means of a double or sliding bolt
we provide a pivotted spring block u (figure 1) in the recess on the steel lump w, in
which the fore end of the sliding bolt usually engages.
By means of this pivotted spring block when the lever e² of the gun is moved and
the bolt is thereby withdrawn out of the steel lump w on the barrels, the block u
moves from the dotted position into the recess previously occupied by the bolt and
thereby blocks or prevents the bolt from entering its recess v; in this position the
block u is represented in full lines.
When the barrels are raised to close the gun, that portion of the under surface of
the block u which projects slightly beyond the lump we will come against the end of
the bolt and will be thereby moved into the dotted position when the recess will be
fully open for the admission of the bolt.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is :-
1. In a drop down snap double bolt gun the use of a lever such as d formed or
fixed on a pin carrying lifting arms substantially as and for the purpose setforth and
as illustrated in the accompanying drawing.
2. The arrangement of safety blocks or catches substantially as and for the purpose
herein before described and as illustrated in the accompanying drawing.
3. The herein described arrangement for facilitating the opening of guns sub-
stantially as setforth.
