PROVISIONAL SPECIFICATION.
An Improved Gun Mounting.
I, ALBERT SAUVÉE, of 22, Parliament Street, Westminster, in the County of
Middlesex, Civil Engineer, do hereby declare the nature of this invention (which
has been communicated to me from abroad by Jean Baptiste Gustave Adolphe
Canet, of 91, Avenue Malakoff, Paris, France, Civil Engineer) to be as
follows:-
The present invention has for its object to provide an improved gun mounting
having the pivot at its forward end, and which enables powerful quick-firing
guns to be employed for arming ships batteries, while keeping the gun port-
holes of small size, causes less obstruction in the vessel, and presents the advan-
tage of enabling the gun to be completely housed within the vessel and to be
made fast against the sides, thereof, or in any other position according to the
construction of such vessel.
This mounting may also be employed in casemates or in any fortifications on
land.
The mounting proper is constructed on the same system as that described
in the Specification accompanying the application for Patent No. 1078 dated
21st January 1890.
The gun during recoil slides through a jacket forming the mounting, and it
carries a cross-head to which the piston rod of the brake is attached. This
jacket-mounting carries the brake cylinder or cylinders, as well as the spring
accumulator, and is connected to a collar in front by two side frames carrying
the trunnions round which the whole cannon and mounting turn to effect the
vertical elevation. The trunnions are mounted upon a frame composed of two
checks, which are cross-stayed and connected to the pivot by a strong bolt.
The carriage on which rests the whole training gear, at its rear end bears upon
the bed through rollers mounted in brackets fixed to the checks.
The pivot bears on the bed through the intermediary of spherical or conical
rollers, and it is secured by a circular clamp to prevent lifting.
The mechanism for the vertical training borne by the carriage consists in a
hand wheel actuating directly (preferably by means of differential gearing) a
driving pinion, gearing with a toothed sector fixed to the jacket-mounting. As
the centre of gravity of the whole of the movable weight is arranged so that it
passes through the axis of the trunnions, the operation of vertical elevation is
rendered very easy.
The lateral sighting is effected either by a lever or by means of a hand
wheel mounted upon the shaft of a worm, which transmits motion to a helicoidal
wheel keyed to a vertical shaft. This shaft is mounted in bearings fixed to the
checks of the carriage, and at its lower end carries a pinion gearing with a circular
rack fixed to the bed.
The gun with its mounting is held in equilibrium round the axis of the pivot,
so that the sighting can be effected by a lever (even on board ship if the rolling
is not too heavy), for which purpose it is only necessary to throw the pinion
engaging the circular rack out of gear.
I employ the same arrangement for housing the gun within the vessel as I have
already used for running in torpedo discharging guns.
For this purpose the mounting is first rendered fixed upon the carriage by
two setting-up screws, and suspended under the beams by screw elevating
blocks connected to two traversing pulleys movable along tracks fixed under the
beams.

page_text: By withdrawing the bolt referred to, the mounting will be disengaged from
the pivot, and may be run back until the mouth of the gun is brought within
the vessel; it is then conducted along lateral tracks which are pivotted so that the
gun can be turned round with its axis parallel to that of the vessel, when it can be
carried back along suitable tracks up to the sides of the vessel.
The mounting can then be secured in this position by passing the bolt which was
first removed through a support fixed to the deck, and. introducing chocks con-
forming to the rear rollers, under such rollers.
It will be readily understood that the arrangements above described may be
employed either separately or combined one with another, and further, that the
materials and the dimensions may be varied to suit requirements without departing
from my invention.

COMPLETE SPECIFICATION.
An Improved Gun Mounting.
I, ALBERT SAUVÉE, of 22, Parliament Street, Westminster, in the County of
Middlesex, Civil Engineer, do hereby declare the nature of this invention (which
has been communicated to me from abroad by Jean Baptiste Gustave Adolphe
Canet, of 91, Avenue Malakoff, Paris, France, Civil Engineer), and in what manner
the same is to be performed, to be particularly described and ascertained in and by
the following statement :-
The present invention has for its object to provide an improved gun mounting
having the pivot at its forward end, and which enables powerful quick-firing guns a
to be employed for arming ships' batteries, while keeping the gun port-holes of
small size, causes less obstruction in the vessel, and presents the advantage of
enabling the gun to be completely housed within the vessel and to be made fast
against the sides thereof, or in any other position according to the construction of
such vessel.
This mounting may also be employed in casemates or in any fortifications on
land.
To enable this invention to be clearly understood I annex drawings hereto showing
the principal arrangements and in which
Fig. 1 is a side elevation of the left hand side of the mounting.
Fig. 2 a plan view thereof.
Fig. 3 a rear elevation, and
Figs. 4 and 5 respectively an elevation and plan view of the working and made
fast positions of the mounting within the vessel.
The mounting proper is constructed on the same system as that described
in the Specification accompanying the application for Patent No. 1078 dated
21st January 1890.
The gun A during recoil slides through a jacket forming the mounting B, and
it carries a cross-head to which the piston rod of the brake is attached. This
jacket-mounting carries the brake-cylinder or cylinders F, as well as the spring
accumulator, and is connected to a collar O in front by two side frames C carrying
the trunnions round which the whole cannon and mounting turn to effect the vertical
elevation. The trunnions G are mounted upon a frame D composed of two cheeks,
which are cross-stayed and connected to the pivot H by a strong bolt 1.
The carriage D on which rests the whole training gear, at its rear end bears
upon the bed through rollers mounted in brackets fixed to the checks.
The pivot H bears on the bed through the intermediary of spherical or conical
rollers, and it is secured by a circular clamp K to prevent lifting.
The mechanism for the vertical training borne by the carriage consists in a hand

page_text: wheel d actuating directly (preferably by means of differential gearing) a driving
pinion, gearing with a toothed sector 6 fixed to the jacket-mounting.
The lateral sighting is effected either by a lever or by means of a hand wheel V
mounted upon the shaft of a worm e, which transmits motion to a helicoidal
wheel keyed to a vertical shaft g. This shaft is mounted in bearings fixed to the
checks of the carriage, and at its lower end carries a pinion gearing with a
circular rack fixed to the bed.
The gun with its mounting is held in equilibrium round the axis of the pivot, 50
that the sighting can be effected by a lever (even on board ship if the rolling is
not too heavy), for which purpose it is only necessary to throw the pinion
engaging the circular rack; out of gear.
I employ the same arrangement for housing the gun within the vessel as I have
already used for running in torpedo discharging guns.
For this purpose the mounting is first rendered fixed upon the carriage by two
setting-up screws k, and suspended under the beams by screw elevating blocks m
connected to two traversing pulleys n movable along tracks p fixed under the
beams.
By withdrawing the bolt I the mounting will be disengaged from the pivot, and
may be run back to the position M when the mouth of the gun is within the vessel;
it is then conducted along lateral tracks q which are pivotted at r so that the gun
can be turned round with its axis parallel to that of the vessel, when it can be
carried back along suitable tracks up to the sides of the vessel at N.
The mounting can then be secured in this position by passing the bolt 1 through
a supports fixed to the deck, and introducing chocks conforming to the rear rollers,
under such rollers.
It will be readily understood that the arrangements above described may be
employed either separately or combined one with another, and further, that the
materials and the dimensions may be varied to suit requirements without departing
from my invention.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. The arrangement of mounting described in which the gun slides freely and
the trunnions are placed in the centre of gravity of the weight movable for vertical
elevation.
2. The employment of a frame composed of two parts-the checks suitably
stayed, and the pivot-these two parts being connected by a single bolt to facilitate
the work of making fast and running out the gun.
3. The arrangement of the different organs enabling the gun to be run in, sub-
stantially as specified.
4. The special arrangements relative to the making fast of the gun along the side
of the vessel or in any position within a battery, in a casemate, or behind a
parapet.
5. The application of each of the arrangements described, or any modifications
of same, either separately or in combination one with another.
6. The complete mounting with forward pivot and equilibriated as described.
