Improvements in Apparatus for Raising Projectiles to Turret Guns."
We, ARTHUR TREVOR DAWSON, of Vickers Sons & Maxim, Limited, of 28,
Victoria Street, Westminster, in the County of London, Superintendent of
Ordnance Works, and JAMES HORNE, of Vickers Sons & Maxim, Limited, of
Barrow-in-Furness, in the County of Lancaster, Engineer, do hereby declare the
nature of this invention to be as follows:-
:
The projectiles for turret guns are usually raised from the store below by a
hoist arranged in a trunk which revolves with the turret. The present invention.
relates to means of transferring the projectiles to the hoist from the places where
they are stored and whence they are conveyed by an overhead traveller to a
truck or bogie which can travel on a track around the hoist trunk.
On this:
truck we provide a vertical shaft which can be turned through worm or other
suitable gear worked by hand or otherwise.
On this shaft are two pinions either of which can be clutched to the shaft,
the clutch being arranged between them so that it is disengaged from the one.
when it is engaged with the other. The lower pinion gears with a circular
rack fixed on the floor of the shell room, the upper pinion gears with a circular..
rack fixed on the hoist itself. On the top of the truck is a tray which is pivotted
on a horizontal axis so that it can be canted.
When it is desired-to raise a projectile to the turret the lower pinion is
clutched to the shaft which is caused to revolve until the truck is brought
round to a position where the projectile is lowered from overhead on to the tray.
The lower pinion is then unclutched and the upper one is clutched to the shaft
which is turned until the truck is brought round to a stop on the hoist trunk
where its tray is in line with the tray on the hoist. The tray of the truck is
then canted so that the projectile roils off it on to the tray of the hoist, by which
it is raised to the turret.

page_text: 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:-
"
The projectiles for turret guns are usually raised from the store below by a
hoist arranged in a trunk which revolves with the turret. The present invention
relates to means of transferring the projectiles to the hoist from the places where
they are stored and whence they are conveyed by an overhead traveller to a truck
or bogie which can travel on a track around the hoist shaft.
For loading this truck with projectiles and transferring these on to the cage
of the hoist we employ apparatus which we shall describe referring to the
accompanying drawings.
Fig. 1 is an elevation of the truck and the lower part of the shaft of the hoist,
Fig. 2 is a part vertical section and Fig. 3 is a part plan of the same. Figs.
and 5 are respectively a side and end elevation of the upper part of the truck
somewhat modified.
On the truck we mount a vertical shaft b which can be turned through worm
or other suitable gear worked by hand or otherwise.
On this shaft are two pinions d e either of which can be clutched to the shaft,
the clutch being arranged between them so that it is disengaged from the one
when it is engaged with the other.
The lower pinion e gears with a circular rack g fixed on the floor of the shell
room, the upper pinion gears with a circular rack fixed on the hoist shaft k.
On the top of the truck is a tray which is pivotted on a horizontal axis so that
it can be canted.
When it is desired to raise a projectile to the turret, the pinion e is clutched
to the shaft which is caused to revolve until the truck is brought round to
a position where the projectile is lowered from overhead on to the tray as shewn
in Fig. 2. The pinion e is then unclutched and the pinion is clutched to the
shaft b which is turned until the truck is brought to a stop on the hoist shaft
where its tray is in line with the tray m on the hoist cage. The tray 7 of the
truck is then canted by a lever so that the projectile rolls off it on to the
trav m of the hoist cage, by which it is raised to the turret.
As shewn in Figs. 4 and 5, the truck instead of having a canting tray as
above described may have a sloping but stationary tray with vertically sliding
stops
stops
connected by a sway beam's to a hand lever by depressing which both
are simultaneously lowered allowing the projectile to roll from the
tray of the truck on to the tray of the hoist cage.
Having now particularly described and ascertained the nature of this in-
vention and in what manner the same is to be performed, we declare that what
we claim is:-
Apparatus for raising projectiles to turret guns constructed and operating
substantially as described with reference to the drawings.
