I, ARTHUR GREENWOOD of the firm of Greenwood and Batley, of Leeds, in the
County of York, Engineer, do hereby declare the nature of this invention to be as
follows:-
My invention relates to magazine or repeating fire arms of the class described in the
specification filed with my application for Letters Patent dated March 17th A.D. 1887
No. 4057, and has for its chief object to increase the capacity of the magazines of
such fire arms without increasing their dimensions, except in width.
According to my present invention I provide the magazine with two chambers
separated by a central partition. Each chamber is provided with a separate plate and
spring for pushing up the cartridges. It will thus be understood that if a magazine
of the kind described in the said Specification is arranged to carry six cartridges the
one now described will carry twelve.
Instead of fixing the magazine to the underside of the "shoe" or breech casing of the
gun as heretofore, I pivot it, preferably towards its lower end, in a loop or guard made
to receive it, each end of which loop or guard is securely fixed to the underside of the
breech casing. The double magazine can thus rock upon its pivots in such a manner
that when it is oscillated to its full extent on one side one chamber comes opposite the
opening in the underside of the breech casing, and when oscillated to the other side,
the other chamber comes opposite to this opening.
In loading the magazine, first one chamber is brought opposite this opening and
filled with cartridges and then the other. When the magazine is being discharged by
the repeating action of the gun each chamber is in the same manner alternately
brought opposite this opening. When the magazine is in a vertical position that is
central between the limits of oscillation, the cartridges remain in the magazine and
the fire arm may be used as a single loader.
The stop or cut off motion described in my former Specification can be used with
this double magazine and perforins exactly the same functions as therein described, so
that by it the repeating action of the gun may be stopped at any time whilst the
cartridges are being used from either chamber in the magazine; or the unspent
cartridges withdrawn from either chamber of the magazine.

page_text: I construct the magazine in such a manner that by the withdrawal of the screws or
pins upon which it is pivotted it may be removed laterally from the loop or guard into
which it is fitted, so that the rising plates and springs in both chambers may be readily
withdrawn.
I arrange a spring or other convenient stop to retain the magazine in its central 5
position or with either chamber opposite the opening in the breech casing.

page_text: Improvements in Magazine or Repeating Fire-arms.
I, ARTHUR GREENWOOD, of the firm of Greenwood & Batley, of Leeds, in the County
of York, Engineer do hereby declaro 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 :-
=
My invention relates to magazine or repeating fire-arms, and comprises improve-
ments in magazines of the kind or class described in the Specification of Letters
Patent dated March 17th A.D. 1887, No. 4057.
The main feature of my present invention is the employment of a double magazine
(that is to say, a magazine divided into two chambers or compartments) which is so
arranged in the gun that it can be moved to bring either of its chambers or compart-
ments into position beneath, or in line with the opening in the shoe or body of the
gun. The feeding of the cartridges into the space in front of the breech-bolt can,
therefore, take place first from one and then from the other of the said chambers or
compartments.
In the accompanying drawing I have shown how my said invention may be
conveniently and advantageously carried into practice.
Figure 1 is a plan of part of a magazine fire-arm with my improvements applied
thereto, the breech-bolt being removed.
Figure 2 is a vertical central section of the same, the breech-bolt being shown in
side elevation.
Figure 3 is a section on the line x, x, Figure 2.
Like letters indicato corresponding parts throughout the drawing.
A is the shoe or body of the gun. B is the barrel. C is the breech-block.
a is the magazine, which has two chambers or compartments b, for the cartridges c,
These chambers are separated by a central partition d. Each of the chambers b, b¹ is.
provided with a separate plate or follower e and spring ƒ for pushing up or elevating
the cartridges c.
My improved magazine, instead of being held firmly in one position in the gun as
heretofore, is pivotted upon screws or pins g inserted in screw-threaded holes in the
loop or guard and extending through the same into holes in the magazine a.
The said loop or guard closes the lower end of the magazine a substantially as
described in my said former specification. It is formed with arms or extensions h³, h³
between which the butt-stock is fixed, and which are firmly secured to the said stock
by screws ³. It is moreover formed with an arm which extends beneath the
forward part of the stock and is firmly secured thereto by a screw. The said
screws h³, h are passed through the said extensions and through the stock and are
screwed tightly into the shoe or body A, thus firmly uniting these parts.
It will be seen that the magazine a can be rocked or oscillated upon the pins g in
such a manner that first one and then the other of the chambers b, b¹ can be brought
opposite or in line with the opening in the underside of the shoe or body A.

page_text: The magazine a is moreover so arranged that, upon the withdrawal of the screws or
pins g, it may be removed laterally from the loop or guard to permit the withdrawal
of the plates or followers e and springs f.
To provide for retaining the magazine a either in its central position or with either
chamber opposite or in line with the opening in the shoe or body A, a stop or catch i
is provided. This stop or catch i has a shoulder or collar against which bears a
spiral (or other) spring. It is, moreover, provided with a conoidal or pointed
extremity which protrudes through a hole or aperture in the loop or guard h and is
adapted to enter one or other of three corresponding depressions in the outside of the
magazine a, which depressions are so arranged as to retain the magazino in either of
the positions above mentioned.
In loading the magazino a, one chamber thereof (b for instance) is brought opposite
the opening in the shoe or body A and filled with cartridges, the magazine is then
turned upon its pivots to bring the other chamber ¹ opposite or in line with the said
opening and this chamber is filled with cartridges.
In using the fire-arm as a repeater, one of the chambers is, in the same manner,
brought opposite the said opening in the shoe or body A and, when all the cartridges
in this chamber have been used, the magazine is oscillated to bring the other chamber
opposite the said opening.
":
When the magazino a is in a vertical position and central between the limits of
oscillation, the fire-arm may be used as a single loader
"with the magazine wholly
or partly charged.
The stop, cut-off or cartridge-catch described in my said former Specification can be
used with the double magazine a as shown at k, and will perform the same functions
as therein described, so that by it the fire-arm may be converted from a repeater to a
"single loader. or vice versa. The unspent cartridges may be withdrawn at any time
from either of the said chambers b, 61, the said stop or catch if used being pulled
outward as described in the said former Specification.
It is evident that, if desired, I can make my magazine to slide laterally in the loop
or guard h, instead of pivoting it therein, for the purpose above specified. I prefer,
however, to adopt the arrangement shown in the drawing. It is, moreover, obvious
that the magazine can be made closed at its lower end and the loop or guard above
described dispensed with if desired.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I wish it understood
that claim :-
First. A magazine which is divided into two chambers or compartments and which
is movable substantially as described so that either of the said chambers or compart-
ments can be brought into position for feeding the cartridges into the gun.
Second. A magazine fire-arm in which my improvements are embodied or
incorporated substantially as described with reference to the accompanying drawing.
