Improvements in Measurement or Try Guns or Fire-arms.
I, HENRY ALFRED ALEXANDER THORN, trading as Charles Lancaster, of
151, New Bond Street, in the County of London, Gun Maker, do hereby declare
the nature of this invention to be as follows:-
My invention relates to measurement or try guns, that is to say, guns, the stocks
of which are adapted to be adjusted in various manners and which are used by
gunmakers to enable them to construct guns to suit the peculiarities of persons of
different build.
Guns of this class whether adapted to be fired or not are usually constructed with
a knuckle or other joint in some part of the handle or stock. This construction,
however, has the disadvantage that when adjusting the said stock to touch the face
the handle and also the butt of the stock are moved disproportionately.
According to my invention I construct a measurement gun with a fixed handle so
that the breech and firing mechanism are quite undisturbed and I provide the
necessary adjustment by making the comb and face of the butt movable both
vertically and laterally so that it can be adjusted for the "bend" or "drop" or
"
cast on or' cast off" as desired.
'
In practice this adjustable comb and face piece is advantageously carried upon a
plate supported upon two vertical slotted standards so that either the comb or the
face may be raised or depressed independently. The plate itself is also provided
with transverse slots to enable the said comb and face piece to be moved for "cast
On or cast off."
"
**
The heel. of the stock is carried upon an auxiliary plate by means of lateral and
vertical guides so that it may be moved laterally or vertically as required.
The auxiliary plate itself is mounted upon a horizontal axis at the end of a
screw running longitudinally into the stock whereby the heel may be adjusted for
length of stock and angle of shoulder. Suitable screws or clamping devices are
provided for holding the adjustable parts in any position in which they may be
placed.
In some cases in addition to making the comb, face and heel adjustable as
described I form a joint in front of the handle to enable the butt to be depressed
or elevated and I mount the barrels upon a vertical axis. In this case in order to
enable the gun to be fired the rear end of the barrels is advantageously curved and
adapted to work against and under a correspondingly curved projecting face by
means of which the breech end of the barrels is closed against the escape
of
gas.

Improvements in Measurement or Try Guns or Fire-arms.
I, HENRY ALFRED ALEXANDER THORN, trading as Charles Lancaster, of
151, New Bond Street, in the County of London, Gun Maker, do bereby declare
the nature of this invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:
My invention relates to measurement or try guns, that is to say, guns, the stocks

page_text: of which are adapted to be adjusted in various manners and which are used by
gun-makers to enable them to construct guns to suit the peculiarities of persons of
different build.
Guns of this class whether adapted to be fired or not are usually constructed
with a knuckle or other joint in some part of the handle or stock. This construction,
however, has the disadvantage that, when adjusting the said stock to touch the face,
the handle and also the butt of the stock are moved disproportionately.
"
وو
According to my invention I construct a measurement gun with a fixed handle.
so that the breech and firing mechanism are quite undisturbed, and I provide the
necessary adjustment by making the "comb and face" portion of the butt movable,
both vertically and laterally, so that it can be adjusted for the "bend or "drop
or cast on or "cast off," as desired, and by mounting the heel of the stock upon
an auxiliary plate, by means of lateral and vertical guides, so that it may be moved
laterally or vertically, as required.
"
The auxiliary plate itself is mounted upon a horizontal axis at the end of a screw
running longitudinally into the stock, whereby the heel may be adjusted for length
of stock and angle of shoulder. Suitable screws or clamping devices are
provided for holding the adjustable parts in any position in which they may
be placed.
To enable my invention to be fully understood I will describe the same with
reference to the accompanying drawings, in which:-
Figure 1 is a side view of the rear part of a gun provided with my improve-
ments:
Figure 2 a plan; and,
Figure 3 an end view:
Figures 4 and 5 are respectively views of the comb and face of the butt and of the
portion of the butt on which it is mounted detached from one another, the said
comb and face being turned upside down:
Figures 6 and 7 are respectively views of the heel of the stock and of the auxiliary
plate on which it is carried detached from one another and shewing their adjacent
faces.
a indicates the stock, 6 the handle thereof, and c, c the barrels. dis the comb and
face-piece which is carried upon a plate e by means of a pivot-stud f secured to a
plate g, working in guides h, h on the underside of the said comb and face-piece d.
With this arrangement it is obvious that the said comb and face-piece may be
turned upon its pivot for moved laterally in either direction. i, i and i, are
respectively screw-bolts and nuts for securing the said piece d in any position in
which it may be placed.
k, kare standards upon which the plate e is carried, which standards slide in slots l,
in the stock and are pivotally connected to the said plate e, so that either end of
the said comb and face-piece d may be raised and lowered and placed at any angle,
for instance, as indicated by the dotted lines in Figure 1. m, m are screws which
serve to lock the said standards in position.
n is the heel of the stock, and o is the auxiliary plate on which the said heel-
piece slides, the said plate being secured to or formed integral with a shank P
carried upon the end of the screw 7, which runs longitudinally into the stock, and
by means of which the distance of the heel-piece from the handle may be regulated.
r, are lock-nuts for firmly holding the screw against rotation when firing the gun.
The shank p is pivotally connected to the screw 9 so that the angle of the heel-
piece relatively to the stock may be adjusted; a suitable screw s being provided to
hold the said shank securely in position.
t is an intermediate plate between the auxiliary plate o and the heel-plate, which
intermediate plate is provided with two sets of slides u, v, the former of which slide
in guides u', ' in the auxiliary plate, whilst the latter slides in a guide v in the
heel-plate. With this arrangement the said heel-plate may be adjusted either
laterally or vertically. w, ware screws for fixing the said heel-piece in any required
position.

page_text: Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what I
claim is :-
The manufacture and use of the improved measurement or try gun or fire-arm
hereinbefore described and illustrated in the accompanying drawings.
