We, Sir W. G. ARMSTRONG, WHITWORTH & COMPANY LIMITED, Manufacturing
Engineers, and SIR ANDREW NOBLE, K.C.B., F.R.S., both of Elswick Works,
Newcastle-upon-Tyne, do hereby declare the nature of this invention to be as
follows:-
-
This invention relates to gun mountings in which two guns are mounted in
cradles so as to recoil in the line of fire.
According to this invention the two gun cradles are arranged side by side
and each cradle is supported by a pair of trunnions, the axis of all the trunnions
being in the same straight line. The two cradles can be coupled together so
that the two guns may be elevated and sighted as a single gun, or they may be
uncoupled and each gun elevated and sighted independently of the other.
The arrangement for coupling the two cradles together is as follows:-
A longitudinal keyway is cut in the adjacent sides of each cradle which are
close together so that when the cradles are adjusted to bring the axes of the two
guns into the same horizontal plane, a key can be inserted in these two key-
ways and so lock the cradles together and prevent one being elevated without
the other. The top edges of the adjacent sides of each cradle are also grooved
longitudinally and a keep or keeps with projections to fit in these grooves, is
bolted to the longitudinal key, the object of the "keep" being to maintain the
axes of the two guns strictly parallel with each other and also to clamp the
longitudinal key securely in place. Each cradle is fitted with the usual elevat-
ing and sighting gear for working the guns separately when the cradles are
uncoupled, and, when the cradles are coupled, the guns may be worked from
either set of elevating and sighting gear or from both sets.

a b are the two guns, c and d are the cradles in which the guns are mounted,
and e ed are their trunnions.

The arrangement for coupling the two cradles c and d together is as follows:-
A longitudinal keyway is cut in the adjacent sides of each cradle which are
close together so that when the cradles are adjusted to bring the axes of the two
guns into the same horizontal plane, a key e can be inserted in these two key-
ways and so lock the cradles together and prevent one being elevated without
the other. The top edges of the adjacent sides of each cradle are also grooved
longitudinally and a keep or keeps f with projections to fit in these grooves, is
bolted to the longitudinal key, the object of the "keep" being to maintain the
axes of the two guns strictly parallel with each other and also to clamp the
longitudinal key securely in place. Each cradle is fitted with the usual elevat-
ing and sighting gear for working the guns separately when the cradles are
uncoupled, and, when the cradles are coupled, the guns may be worked from
either set of elevating and sighting gear or from both sets.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is:-
1. The combination of two guns mounted side by side in two cradles whose
trunnions are in a line with each other with means for coupling the cradles
together.
2. In apparatus such as is referred to in Claim 1 coupling the cradles together
by means of a longitudinal key substantially as described."
3. The means for coupling the cradles together substantially as described and
illustrated in the drawings.
4. Gun mountings substantially as described and illustrated in the drawings.
