Improvements in Gun-mountings.
I, HENRY HARRIS LAKE, of the firm of Haseltine Lake & Co., Patent
Agents, 45 Southampton Buildings, in the County of Middlesex, do hereby
declare 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:-
This invention relates to protected gun-mountings wherein the gun is connected
with an armour plate cover or crown without the intervention of recoil brakes so
that the force of recoil is transmitted directly and entirely to the said armour plate.
In such a gun mounting owing to the great weight of the parts that take up the
force of recoil the amount of recoil is reduced very considerably as compared with
other mountings, therefore the operation of the gun is much simpler and the
protected space required is less than in the case of guns which recoil on the
mounting.
The object of this invention is to provide for very advantageously mounting the
gun in the gun-carriage.
In the accompanying drawing,
Figure 1 is a side elevation of an armour-plated gun carriage or mounting
constructed according to this invention, the armour-plated crown being shown in
section.
Figures 2 and 3 are views illustrating a detail of the invention hereinafter
described.
A is the shallow curved armour plate cover or crown provided with the
embrasure B and resting upon and secured to two vertical parallel cheeks C of the
gun carriage or mounting. These cheeks are connected with each other at their
lower ends by a horizontal cross-piece D. On their inner side the aforesaid cheeks
have grooves E curved to an arc of a circle the centre of which is in the centre of
the embrasure B.
The gun F is formed with side projections G in lieu of trunnions, said projections
being curved to the same radius as the grooves E and adapted to fit in the latter.
By moving the projections G up and down the grooves E the gun is caused to pivot
about an imaginary axis in the centre of the embrasure B and the elevation or
vertical pointing of the gun is thereby changed. In consequence of this construc-
tion the embrasure B may be made very small. The cheeks C are supported by
central pivot C¹ which is capable of turning about a vertical axis, and the training
of the gun is effected by turning the cheeks in any suitable manner about the said
pivot. The gun F cheeks C and armour plate cover or crown A all turn
together.
&
Instead of making the sliding pieces G in one piece with the gun as shown in
Figure 1 they are sometimes formed according to this invention in a separate piece
or clip which is adapted to be secured to the gun by bolts or otherwise. The said
clip is conveniently constructed in halves as shown in Figures 2 and 3, which
halves H H are bolted together on the gun. For the better securing of the clip I
provide on the gun a collar F¹ Fig. 3 and I form in each half of the clip a recess
adapted to fit on the said collar and thus prevent slipping of the gun through the
clip. Two projecting pieces G on each side of the gun are shown in Figures 2
and 3 in lieu of one as shown in Figure 1.

page_text: Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, as communicated to me by
my foreign correspondent, I declare that what I claim is :-
First. A gun-mounting wherein the gun is provided with curved projections
adapted to slide in curved grooves formed in the checks of the gun-carriage, said
cheeks being attached to an armour plate cover or crown without the intervention
of recoil brakes, substantially as herein described for the purpose specified.
Second. The modification of the invention wherein the projections for guiding the
gun are formed on clips adapted to be attached to and removed from the gun,
substantially as set forth.
