Patent – Daniel Moore

US 30079

Be it known that I, Daniel Moore, of Brooklyn, in the county of Kings and State of New York, have invented, made, and applied to use certain new and useful Improvements in Revolving-Breech Fire-Arms; and I do hereby declare that the following is a full, clear, and exac description of the construction and operation of the same, reference be ing had to the annexed drawings, making part of this specification, wherein Figure 1 is a side elevation of my improved arm, and Fig 2 is an end view with the bar
rel and cylinder removed and the center-pin on which the cylinder revolves in section. Similar letters refer to the same parts.

My said invention relates to a means for
attaching the stock, barrel, and cylinder, so
that said cylinder can be swung aside from
the stock for the purpose of loading or remov.
ing the charge from the piece; but when in
position for firing said parts are.held firmly
together. My revolving-breech fire-arm is
adapted to volcanic cartridges, in which a me.
tallic capsule contains the powder and receives
the ball, a hollow flanged ring being provided
for the fulminating material around the base
of the cartridge.
In the drawings, a is the stock, of any usual.
size or shape. b is the barrel, either rifled or
plain. c is the cylinder of chambers or revolv
ing breeches. d is the metallic breech-piece
behind the chambers, and e is a connection
therefrom beneath the chambers c to the
bracket f on the lower side of the barrel b.
These parts e and fare attached to each other
by a gudgeon, l, projecting from the former
and passing through a hole in the bracket f,
and 2 is a nut securing the barrel and bracket
to the stock. –
The center-pin 3, on which the chambers c
revolve, is formed as shown by dotted lines
in Fig. 1. The forward end of this pin enters
the part f below the barrel, where it is secured in place by the screw 4 or any competent means, and a shoulder on this pin serves
to prevent the chambers disconnecting or slid
ing off the pin when the barrel is disconnected
from the stock. On the rear end of the pin 3
is a collar by which the stock and barrel are
connected. For this purpose I provide a re
cess in the breech-piece d, as seen at g in Fig.
2. This recess is formed large enough at one
end to pass the said collar, and is undercutor
grooved, so that when the barrel and stock
are in properline the said recess contains the

pin and the collar of the end thereof in the space formed behind for the same, as seen in
Fig. 2. It will now be evident that when the .
barrel and chambers are turned aside on the
gudgeon 1 to the position shown by red lines
in Fig. 2 that some of the chambers are clear
of the metallic breech-piece d and are open
from end to end, so that the said chambers
can be cleared of the metallic cartridge-case
and a new cartridge, inserted, and the cylin
der can be revolved while in this position so
as to give access to the respective chambers.
When turned back to its place the collar on
the end of the pin 3 makes a firm connection
between said pin and the breech-piece d.
To prevent the cylinder and barrel swing–
ing aside when in use, I provide the latch i,
which, springing into a notch in the collar of
said pin 3, retains the parts in position for fir
ing. The end of this latch, projecting from
the side of the metallic breech-piece, allows
for its being moved by the thumb or finger
when the breeches are to be swung aside.
k is the hammer for exploding the car
tridge, the same being actuated by a suitable
mainspring. is the trigger; m, the pawl for
revolving the cylinder of breeches, and n is
the stop for holding the respective chambers
in line with the barrel. These various parts
k, l, m, and in do not form any part of my
present invention. They may therefore becon
structed and operate in any well-known man
ner, and as is usual in this character of fire
a S.
The advantanges of this means for connect
ing the barrel and stock will be apparent, for
the explosion is sustained by the center-pin 3
and gudgeon 1. At the same time free access
to the chambers is easily obtained. –
Having thus described my said invention,
what I claim, and desire to secure by Letters
Patent, is
The center-pin 3 and its collar at the back
end, retained within the recess g, combined
with the cylinder c and barrel b, swinging on
the gudgeon 1 in the manner and for the pur
poses set forth, and in combination with said
center-pin 3, moving as aforesaid, the latch i,
to retain the parts in place while the arm is
being discharged, as specified.
In witness whereof I have hereunto set my
signature this 17th day ofJuly, 1860,
