Improvements in Drop Down Breech Loading Guns and Small Arms.
We, JOHN DEELEY, of No. 82, High Street, Birmingham, in the County of
Warwick, Gun Manufacturer, and LESLIE BOWN TAYLOR, of No. 129, Pershore
Road, Birmingham aforesaid, Gun Maker, do hereby the nature of this invention
to be as follows:-
Our invention consists of the improvements hereinafter described in drop down
breech loading guns and small arms principally of the kind described, represented
and claimed in the Specifications of Letters Patent granted to William Anson and
John Deeley dated and numbered respectively 11th May 1875 No. 1756 and 11th
April 1883 No. 1833, the said improvements having for the object to facilitate the
removal of the lock mechanisms of the said guns, and small arms for cleaning
or repair.
In order that our invention may be the better understood we remark that the
hammers sears, and cockers or lifters of guns and small arms of the Anson and
Deeley type are secured in position by and turn on pins or pivots crossing the
body of the gun from side to side, and when it is wished to remove the lock
mechanism of the gun for cleaning or repair it is necessary to withdraw the said
pins and thereby to disarrange and separate the various parts of the lock
mechanism.
By the use of our invention the said lock mechanism is made capable of ready
removal and replacement without the use of special tools. Further, the lock
mechanism is removed as a whole that is without the separation of its individual
parts.
"
We will describe our invention in connection with an Anson and Deeley double
barrel gun or small arm, but we wish it to be understood that our invention is
applicable to other guns and small arms of a similar type.
According to the improvements constituting our invention we arrange the several
parts of the lock mechanism at each side of the gun on a plate which plates are
fitted into slots in the body of the gun, the hammers, sears and cockers of lifters
being pivotted to pins preferably made in one piece with the plates by which the
said parts are carried." The front or knuckle end of the slots in the body of
the gun are undercut so that the plates engage in the said slots by a hook like
action. The plates are secured in position and the body of the gun made
practically dust proof by the bottom cover plate of the said body of the gun,
the said cover plate being secured by a screw taking into the body. It is hence
only necessary to withdraw the said screw in order to permit of the removal of
the bottom cover plate when the lock mechanism may be wholly detached from
the gun for cleaning or repair and afterwards replaced and fixed in position by the
fixing of the bottom cover plate by the screw described.

page_text: The bottom cover plate may be made in one piece with one or both of the lock
plates.

Improvements in Drop Down Breech Loading Guns and Small Arms.
We, JOHN DEELEY, of No. 82, High Street, Birmingham, in the County of
Warwick, Gun Manufacturer, and LESLIE BOWN TAYLOR, of No. 129, Pershore
Road, Birmingham aforesaid. Gun Maker, do hereby declare the nature of the
said 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 consists of the improvements hereinafter described in drop down
breech loading guns and small arms, principally of the kind described, represented
and claimed in the Specifications of Letters Patent granted to William Anson and
John Deeley dated and numbered respectively 11th May 1875, No. 1756 and 11th
April 1883, No. 1833, the said improvements having for their object to facilitate the
removal of the lock mechanisms of the said guns and small arms for cleaning
or repair.
In order that our invention may be the better understood we remark that the
hammers, sears and cockers or lifters of guns and small arms of the Anson and
Deeley type are secured in position by and turn on pins or pivots crossing the
body of the gun from side to side, and when it is wished to remove the lock
mechanism of the gun for cleaning or repair it is necessary to withdraw the said
pins and thereby disarrange and separate the various parts of the lock
mechanism.
By the use of our invention the said lock mechanism is made capable of ready
removal and replacement without the use of special tools. Further, the lock
mechanism is removed as a whole, that is, without the separation of its individual
parts.
We will describe our invention in connection with an Anson and Deeley double
barrel gun or small arm but we wish it to be understood that our invention is
applicable to other guns and small arms of a similar type.
According to the improvements constituting our invention we arrange the several
parts of the lock mechanism at each side of the gun on a detachable plate, which
plates are fitted into slots in the body of the gun, the hammers, sears and cockers
or lifters being pivotted to pins preferably made in one piece with the plates by
which the said parts are carried. The rear end of the plate is provided with a
semi-circular notch or depression which engages with a stop stud on the side of the
slot in the body and the front or knuckle end of the body may be slightly
undercut for the front end of the plate to engage with it by a hook like
action. The plates are secured in position and the body of the gun made
practically dust and water proof by the bottom cover plate of the said body of the
gun, the said cover plate being secured by a screw taking into the body. It is hence
only necessary to withdraw the said screw in order to permit of the removal of
the bottom cover plate when the lock mechanism may be wholly detached from
the gun for cleaning or repair and afterwards replaced and fixed in position by the
fixing of the bottom cover plate by the screw described.
The bottom cover plate may be made in one piece with one or both of the lock
plates.

end of an Anson and Deeley double barrel gun containing our improvements;
Figure 2 is a plan of underside of the same; Figure 3 is a front elevation of the
body of the said gun. The barrels of the gun are omitted in Figures 2 and 3.
Figures 4 and 5 represent in side elevation and plan of underside respectively
one of the lock mechanism carrying plates (with sear spring attached) separately;
and Figures 6 and 7 represent elevations at opposite sides of one of the lock
mechanism carrying plates with the lock mechanism in position on the said plate.

bottom edge of the detachable lock carrying plate a, a projection or stop a³ (see
Figure 6) is provided to prevent the cocker or lifter d from moving too far or
going beyond its proper position or to maintain it in its position when the lock
is removed from the body. The said plate a also has in one piece with it the
pin's br studs a², a³, a on which the hammer c, lifter or cocker d and sear e are
respectively fitted and turn. The said pins a³, a³, a' are preferably hollow and
internally screw threaded the screws for fixing the hammer c, lifter or cocker d
and sear e taking into the hollow screws, the heads of the screws taking in depres-
sions in the hammer, lifter and sear and lying flush with the outer side of the
said hammer, lifter and sear as will be understood by reference to the fixing of
the hammer c in Figure 9. The sear spring f is preferably fitted by a dovetail
joint to the lock mechanism carrying plate a, a projection formed on the
sear e projecting into an opening in the lock mechanism carrying plate and bearing
on the acting end of the said sear spring f.
The detachable lock mechanism carrying plates a, a with their lock mechanism,
are passed first by an inclined or nearly endwise motion into the rear ends of the
slots g, g at opposite sides of the body of the gun, by which inclined or endwise
motion the notches h, h in the rear ends of the lock mechanism carrying plates a
engage with side stop pins i, i projecting into the slots g, g in the said body; the
said lock carrying plates are then raised and turning on the said side stop pins i, i
as joints take their proper position in the slots g, g and may be fixed in position
by the side screw pins p, P passed through holes in the body and taking into
screwed holes in the lock plates.
In addition to the stop pin i and notch h the front end of the plate a may be so
shaped as to engage by a hook like action with a spring bolt or retainer at the
front of the slot in the body. A detachable plate with a hook like seat at its
front is marked x in the separate view of the plate Figure 10, and the spring
bolt marked y is represented in Figure 11 engaged with the hook like seat of
the plate, the said Figure 11 representing a longitudinal section of the body of the

notch has been engaged with the pin i the front end of the lock plate is raised
in the slot in the body. The bolt y is thereby pressed back by the projection y²
and when the plate has been fully raised the bolt y snaps under the seat and
secures the plate in the slot as seen in Figure 11. On the depressing of the front
end of the plate its projection y² presses back the bolt y and permits of the removal
of the plate from the body.
The said lock mechanism carrying plates a are further preserved in place by the
5 bottom or cover plate which preferably slides in dovetail grooves in the sides
of the body of the gun (see Figure 3) and is fixed by the screw indicated in

page_text: dotted lines in Figure 1, taking into the screwed. hole
body of the gun.
(see Figure 2) in the
The front or knuckle end of the body has large slots or openings k, k through
which the dogs or arms on the fore end project for operating the lifters or
cockers d, d on the opening of the gun.
The sear e is without the ordinary right angled projection at its tail end in
order that the locks may be readily placed in position in the body, and a stud m
(see Figure 1) is formed on or secured to the trigger blade to operate the sear in
the usual way.
From the description herein before given it will be understood that when it is
desired to withdraw the lock mechanism for cleaning or repair it is only necessary
to withdraw the screws 1 and p, p and take the bottom or cover plate 1, by a
sliding motion, from the body of the gun when the lock mechanism carrying
plates a may be withdrawn from the slots g, g and from engagement with the
bolt
and stop pins i, i the said plates a bringing with them the whole of the lock
mechanism in an undisturbed condition. After cleaning or repair the lock
mechanism may be as readily replaced.

The application of our improvements to drop down breech loading guns and
small arms of a similar type to the Anson and Deeley gun differs in no essential
respect from its application to an Anson and Deeley gun as herein before described
and illustrated.
Having now particularly described and ascertained the nature of our inven-
tion and in what manner the same is to be performed we declare that we claim
as our invention of "Improvements in drop down breech loading guns and small
وو
armg :-
The combination with drop down breech loading guns and small arms of the
Anson and Deeley type and guns of a similar type, of detachable plates a, a carrying
the lock mechanism, the said detachable lock carrying plates being constructed
and the parts used therewith arranged substantially as herein before described
and illustrated in the accompanying drawing.
