PROVISIONAL SPECIFICATION.
An Improvement in Running Out Springs for Guns.
We, VICKERS, SONS, & MAXIM, LIMITED, of River Don Works, Sheffield, in
the County of York, ARTHUR TREVOR DAWSON, and GEORGE THOMAS BUCKIIAM,
both of Vickers, Sons, & Maxim, Limited, of 28, Victoria Street, Westminster,
in the County of London, do hereby declare the nature of this invention to
be as follows:-
This invention relates to the construction of the running out spring for a
gun in such a manner that it can be readily adjusted to the required degree
of compression, and (when so adjusted it can, when desired, be removed from
the gun and cradle without having its adjustment altered.
For this purpose, the spring, which may be in several lengths separated by
washers, is held in a tubular casing through which passes a central tubular
bolt.
I
The rear end of this bolt which is fixed by a retaining nut in a bracket pro-
jecting down from the gun, has a shoulder against which can bear a piston-
shaped collar the boss of which can slide on the central bolt, while its periphery
fits within the tubular casing. The front end of the central bolt is internally
threaded to receive a compressor screw, the head of which bears on a piston-shaped
collar like that at the rear end so that, by turning the screw and thus advancing
this collar, the spring is compressed between it and the rear piston-shaped collar
to the desired extent.
1
On the rear end of the tubular casing is formed a sectional screw-thread,
or a set of sectional collars as on the breech plug of a gun, and on this is fitted
a cap which has an internal flange bearing against the rear piston-shaped collar.
The tubular casing being attached to the cradle in which the gun slides, the
gun, when it recoils, draws back the central bolt and front piston-shaped collar
compressing the spring, which afterwards expanding, causes: these parts to move
forwards advancing the gun to firing position.
When it is desired to remove the spring, the retaining nut on the rear of the
central bolt is unscrewed, the casing, spring, and central bolt can then be all
removed together without any alteration of the spring adjustment.

page_text: in the County of London, 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 the construction of the running out spring for a
gun in such a manner that it can be readily adjusted to the required degree
of compression, and when so adjusted it can, when desired, be removed from
the gun and cradle without having its adjustment altered.
For this purpose, as shewn in longitudinal section in the accompanying draw-
ings, the spring a which may be several lengths separated by washers b is
held in a tubular casing c through which passes a central tubular bolt d.
The rear end of this bolt which is fixed by a retaining nut in a bracket e
projecting down from the gun, has a shoulder against which can bear a piston-
shaped collar f the boss of which can slide on the central bolt d while its periphery
fits within the tubular casing c. The front end of the central bolt d is internally
threaded to receive a compressor screw g the head of which bears on a piston-
shaped collar h, like f, at the rear end, so that, by turning the screw g and thus
advancing this collar h, the spring is compressed between it and the rear piston-
shaped collar f to the desired extent.
On the rear end of the tubular casing c is formed a sectional screw-thread, or
a set of sectional collars k as, on the breech plug of a gun, and on this is fitted
a cap which has an internal flange bearing against the collar f.
The tubular casing being attached as at n to the cradle in which the gun slides,
the gun, when it recoils, draws back the central bolt and the collar h, com-
pressing the spring, which afterwards expanding, causes these parts to move
forwards advancing the gun to firing position.
When it is desired to remove the spring, the retaining nut a on the rear of
the central bolt d is unscrewed, the casing c, spring a and central bolt d can
then be all removed together without any alteration of the spring adjustment.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what we
claim is:-
A running out spring for a gun held in tubular casing between two piston-
like collars fitted on a central tubular bolt, the rear end of which is detachably
secured to a bracket projecting down from the gun, and its front end is internally
screw threaded to receive an adjusting screw, the head of which bears on the
front collar, the rear end of the casing having sectional screw threads or collars
to receive a cap, an internal flange of which bears on the rear piston-like collar,
substantially as and for the purpose set forth.
