IMPROVEMENTS IN SMALL ARMS
Year: 1884

page_text: I MICHAEL KAUFMANN, of 11 Wellington Street, Strand, London, Merchant, do
hereby declare the nature of my invention for "IMPROVEMENTS IN SMALL ARMS"
to be as follows:-
My Invention relates to certain improvements in fire-arms, especially applicable
to pistols and revolvers.
The object of my invention is to provide a pistol or revolver with a lock-covering-
plate and handle which may be easily and quickly mounted or dismounted without
the use of a screw driver or any other instrument so as to have ready and rapid
access to the lock of the fire-arm. I dispense with the usual screws used for fixing
the lock-covering-plate and handle, and I use no springs for securing the said plate
and handle.
I propose to attain my object by the following means. I provide the lock-
covering-plate at both ends with a prolongation or nose. In the body of the pistol
or revolver I make a groove or inlet to receive one prolongation or nose of the
plate, and I provide the pistol or revolver with a key, arm or fastener so arranged,
as when turned or pushed, it may come over the other prolongation or nose of the
lock-covering-plate for the purpose of fastening or locking the plate after it has
been placed in position.
I further provide one of the wooden handles or plates of the pistol or revolver.
with a metal band say of steel, forming at one end a projection to come under the
lock-covering-plate and at or near the other end an upright or horizontal projection
containing a threaded hole for the purpose of receiving a screw fitted in the weapon.
The band is further provided with a stud or button adapted to enter a hole in tho
frame of the weapon.
.
Near the end of the butt of the pistol or revolver is a screw with a large head, of
a size to be conveniently turned or screwed by the hand only. A part of this screw
I make of a smooth surface and of a smaller circumference in the centre of its
length, so as to form a shoulder near either. end. Beyond the one shoulder; at that
part which enters the interior of the revolver it is threaded and forms a screw to
engage with the hole in the projection of the metal band, for the purpose of securing
the wooden handle of the weapon. In the frame of the weapon is a small screw or
pin against which either shoulder of the large screw acts to prevent the said largo
screw from becoming detached from the weapon.

page_text: I also provido a ring, pierced with a hole to receive the exterior shoulder of the
screw and to rotate freely thereon, so that when the said ring is turned it cannot
possibly displace the screw or disturb the security of this locking device.
I may modify the above arrangements.
Instead of the projection of the metal band, coming under the lock-covering-
plate, I may make that end of the wooden handle beveled or inclined, and likewise
make the side of the lock-covering-plate beveled or inclined, so that the one end
of the wooden handle may rest under, and be secured by, the lock-covering-plate.
I may also dispense with the threaded hole in the projection of the band and make
a hole of a smooth surface either in the metal band or in the solid wood, to receive
a smooth end of the screw forming the locking device. This screw I may also
modify so as to screw into the butt or rear end of the frame of the pistol or
revolver.
I propose to fusten the other wooden plate or handle of the weapon from the
interior with one or two screws or other suitable means.
MICHAEL KAUFMANN 11 Wellington Street, Strand, London, Merchant do
hereby declare the nature of my invention for IMPROVEMENTS IN SMALL ARMS
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 certain improvements in Small Arms (especially applicable
to pistols and revolvers) hereinafter fully described, reference being had to the
accompanying sheet of drawings.
BY
The object of my invention is to provide a pistol or revolver with a lock-covering-
plate and wooden sides of the handle, secured by a locking-dévice, easily mounted
or dismounted, and permitting of a ready and rapid access to the lock of the fire-
arm, without the use of a screwdriver or any other instrument.
I
'
I dispense with the usual screws used for fixing the lock-covering-plate and
wooden sides of the handle, and I use no springs for securing the said plate and
handle.

B, the lock-covering-plate.
C, Screw adapted to secure the wooden sido A of handle and serving as a
locking-device.
D. Ring with collar attached, adapted to rotate on the neck c³ of the screw C.
E. Rubber or fastener for securing the lock-covering-plate B.
A hole is pierced in the main fraine at the butt-end of the revolver and threaded
to receive the scrow C.
The screw C is of the form shown in figures 1 and 5-It is screwed into the
frame of the revolver at the butt end and is provided at its point with a smooth
surface adapted to enter the hole m³ in the metal plato of the wooden side A.
The screw Ċ near its point is adapted to receive a small screw T which prevents
the screw C, when in position, from being inadvertently detached from the revolver.
The head c of the screw C is sufficiently large to permit tlie screw being turned
easily with the hand only.
The ring D is provided with a collar pierced with a hole at W, adapted to receive
the screw C, the ring D rotating freely on the neck of the screw C.
The lock-covering-plato B is provided at one end with a prolongation or nose P
which enters a groove p in the body of the revolver, and is provided at the other
end, with a prolongation or nose O, which engages with the rubber or fastener E.
The plate B is also provided with a stud a adapted to enter the frame of the weapon.
The rubber or fastener E is attached to the frame of the revolver and may be
turned from right to left or from left to right for the purpose of securing or
liberating the lock-covering-plate B.
The wooden side A of handle is provided with a metal plate R having a stud L
adapted to enter a hole S in the frame of the revolver, the metal plate R having
also an upright or perpendicular projection K provided with a hole m¹ adapted to
receive the point C' of the screw C.
The wooden side A of handle is also provided with an opening Y adapted to
receive and hold in position the rubber or fastener E. The end H of the wooden
side A is a projection adapted to come under the lock-covering-plate B.
The other wooden side of the handle, see fig: 4 is provided with a metal plate a
having a screw hole b¹, adapted to receive the screw b, screwed from the interior of
the weapon, see fig 1, and is not required to be detached from the weapon in order
to gain access to the lock.
To mount the lock-covering-plate and handle:
Insert the prolongation P of the covering-plate B into the groove p of the body
of the revolver, and place the covering plate in its position covering the lock, then
turn the rubber or fastener E so that its end E' coming over and pressing firmly
against the projection or nose O of the covering-plate, secures it. Next insert the
projection H of the wooden side A of the handle under the cover plate B, placing
the wooden side in position so that the rubber or fastener E fits into the opening Y,
and the stud L enters the hole S in the frame of the weapon-Lastly, turn the
large head of the screw C until its point C enters the hole m¹ of the metal
plate R and firmly secures the wooden side A. In this position, the handle and
covering-plate are securely locked, and the ring being arranged to rotate freely, it
cannot disturb the security of the locking-device.
To dismount the lock-covering-plate and handle:
Turn the screw C until it is disengaged from the wooden side A of the handle,
remove the wooden side A, turn the rubber or fastener Ę until it is disengaged from

page_text: the nose O of the covering-plate B and then remove the covering-plate B, which
lays bare the lock for the purpose of cleaning etcetera..
I may modify the arrangement I have immediately above described, as shown in
figures 8, 9 and 10. In this case I provide the wooden side A of the handle with
a long metal band, whose projection H is adapted to come under the covering-
plate B-I also provide this metal band with a perpendicular projection K
containing a threaded hole m adapted to receive a screw C fitted in the butt-
end of the weapon.
That part of the screw C which enters the butt-end of the revolver is of a smooth
surface and of a smaller circumference in the centre of its length, so as to form a
shoulder near either end, and the frame of the weapon is provided with a pin N
against which either shoulder of the screw C acts, the pin N preventing the screw C
from becoming detached from the weapon.
The point end of the device C is threaded and forms a screw adapted to fit into
the threaded hole m of the projection K of the wooden side A of the handle, for the
purpose of securing it.
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 :-
1. In a small-arm, a handle dismountable by hand, and secured by a
device at its butt end, substantially as set forth.
2. The lock-covering-plate B as fully described.
3. The rubber or fastener E as fully described.
locking-
4. The screw C constituting a locking device of the handle and carrying a ring
substantially as set forth.
5. The ring with collar rotating on the screw C substantially as described.
