IMPROVEMENT IN REPEATING OR MANY-CHAMBERED FIRE-ARMS.
Specification forming part of Letters Patent No. 677, dated April
To all whom it may concern:
Be it known that we, Henry Daniels and Charles Daniels, of
Chester, in the county of Middlesex and State of Connecticut,
have invented an Improvement in Repeating or Many-Chambered
Fire-Arms, and we do hereby declare that the following is a full
and exact description thereof.
Figure 1 in the accompanying drawings shows a perspective view of
one gun; and Fig. 2, a section thereof, showing the interior of
the chambered receiver and other parts connected therewith.
In both drawings the same letters of reference are used to
designate the same parts.
A A is the receiver, which is perforated, to contain the charges.
It will be seen in Fig. 1 that this is made octagonal on its
periphery, which form we prefer to that of a circle as being more
secure and presenting other advantages. It may, however, be made
circular and still have the projecting rim around the chamber,
which constitutes a principal part of our improvement.
B B are the chambers, which are to contain the load, and these
chambers have each a projecting rim, C C, which may be made
conical, there being an excavation or recess at the back end of
the barrel, into which said conical rim is to fit accurately.
Instead of making the projecting' rim conical, I sometimes make
its outer edge rounding, thereby avoiding a sharp edge and
causing it to enter its proper recess the more smoothly. In order
to cause the projecting rim to enter the recess provided for it
at the back end of the barrel, it will be evident that the
receiver must be made to recede and advance as the respective
chambers are made to coincide with the bore of the gun, carbine,
rifle, pistol, or other fire-arm, and this we effect in the
D is an axis, upon which the receiver revolves, which axle is
made oval, or is otherwise so formed in that part of it which
passes through the receiver that by turning it round it shall
operate a cam or eccentric and serve to force the rim of the
chamber into the recess of the barrel and confine it firmly there
during the discharge.
E is a short lever, by the turning of which the axle is made to
revolve and the receiver caused to advance or allowed to recede,
as may be required. This lever is attached by a neck or collar to
the upper stock-strap, F, so that when this shaft is turned up to
change the receiver it need not be removed. The upper end of the
axle, which is squared, passes into an opening in the neck of
A spiral, zigzag, or other spring, G, is inserted in the stock,
as shown in the drawings, and bears against a plate of metal,
which comes into contact with the periphery of the receiver,
bearing against it with sufficient force to hold it in its place,
and yet allowing it to turn round smoothly.
The upper stock-strap, F, is hinged to the barrel, as shown in
the drawings, and when in place is held down by a turn-buckle,
catch, or other similar contrivance.
The mode of affixing the percussion-caps and of constructing the
lock is similar to that adopted in some other guns, and will be
manifest upon inspecting the drawings.
What we claim as our invention, and wish to secure by Letters
1. The formation of the projecting rims around the mouth of the
chambers, with the corresponding- recesses at the back end of the
barrel, as described.
2. The forming of the revolving axis which passes through the
receiver in such a way as that it shall form the said rims into
their corresponding recesses and hold them firmly there during
the discharge of the piece, together with the use and arrangement
of spiral or other springs within the breech.
