We, SAXTON WILLIAM ARMSTRONG NOBLE and RALPH THEW BRANKSTON, both
of Elswick Works, Newcastle-upon-Tyne, do hereby declare the nature of this
invention to be as follows:-
The chief object of this invention is to obtain ready access to the balls and
training gear for examination purposes in mountings of the pedestal type. A
mounting in accordance with our invention is represented by Figure 1 of the
annexed drawings.
Ä
The pedestal A is securely bolted to the deck, upon it is formed a stem B upon
which the carriage is fitted. The carriage C is formed at the top with brackets D
at each side to take the trunnions of the cradle. The base part of the carriage E
is formed hollow and fits on to the stem B of the pedestal. The carriage is
carried upon a ring of balls which run upon hard steel rings as shown on the
drawings. A steel pin F is fixed on to the top of the pedestal and serves to carry
the training worm wheel and also the lower hard steel ring for the balls.
circular piece G is provided to carry the upper rings for the balls; it is bolted
to a flange H on the carriage by bolts I and when these bolts are screwed down
the weight of the gun and carriage is taken on the balls. The training worm
wheel J is carried on the pin F and is secured to it by friction the necessary
amount of friction being obtained by screwing down the nut K on to the spring
washer L and compressing the worm wheel between the washers M. M.
When examination of the balls is necessary the training wheel is removed and
the bolts I slackened; the flange H then rests on the top of the pedestal, and
the circular piece F can be lifted off and the balls examined.
Figure 2 shows another arrangement for the attainment of the same object;
in this case the usual form of pedestal is retained. At the base of the pedestal
a base plate N is secured by means of bolts; upon this plate rests a round pillar O
which fits into a hole bored in the shank of the carriage P. Upon the top of this
pillar is provided a ball race upon which the weight of the gun and carriage is
taken. The balls are carried in a screwed plug Q which screws into the carriage
and by screwing this plug down into position the weight of the gun and carriage
is taken on the balls. Ready access is then obtained to the balls for examination
purposes by unscrewing the plug.
Figures 3 and 4 show a method by which the balls can be removed from the
side of the pedestal, a rectangular recess is cut in the pedestal and a block S is
fitted into it containing the balls. On slightly lifting the carriage the block S
can be withdrawn for the examination of the balls.
Figure 5 shows another method of obtaining ready access to the balls. The
balls are placed under the carriage T, the removable piece T¹ being fitted in

page_text: halves; when it is removed and the carriage slightly lifted the balls are readily
examined.

Improvements in Gun Mountings.
We, SAXTON WILLIAM ARMSTRONG NOBLE and RALPH THEW BRANKSTON, both
of Elswick Works, Newcastle-upon-Tyne, 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:-
The chief object of this invention is to obtain ready access to the balls and
training gear for examination purposes in mountings of the pedestal type. A
mounting in accordance with our invention is represented by Figure 1 of the
drawings annexed to the Provisional Specification. The figure is a side elevation
for the most part in section, a part only of the gun and of the cradle is represented.
The pedestal A is securely bolted to the deck, upon it is formed a stem 13 upon
which the carriage is fitted. The carriage C is formed at the top with brackets D
at each side to take the trunnions of the cradle. The base part of the carriage E
is formed hollow and fits on to the stem B of the pedestal. The carriage is
carried upon a ring of balls which run upon hard steel rings as shown on the
drawings. A steel pin F is fixed on to the top of the pedestal and serves to carry
the training worm wheel and also the lower hard steel ring for the balls.
circular piece G is provided to carry the upper rings for the balls; it is bolted
to a flange H on the carriage by bolts I and when these bolts are screwed down
the weight of the gun and carriage is taken on the balls. The training worm
wheel is carried on the pin F and is secured to it by friction the necessary
amount of friction being obtained by screwing down the nut K on to the spring
washer L and compressing the worm wheel between the washers M. M.
Ä
When examination of the balls is necessary the training wheel is removed and
the bolts I slackened; the flange H then rests on the top of the pedestal, and
the circular piece G can be lifted off and the balls examined.
Figure 2 shows another arrangement for the attainment of the same object;
in this case the usual form of pedestal is retained. At the base of the pedestal
a base plate N is secured by means of bolts; upon this plate rests a round pillar O
which fits into a hole bored in the shank of the carriage P. Upon the top of this
pillar is provided a ball race upon which the weight of the gun and carriage is
taken. The balls are carried in a screwed plug Q which screws into the carriage
and by screwing this plug down into position the weight of the gun and carriage
is taken on the balls. Ready access is then obtained to the balls for examination
purposes by unscrewing the plug.
Figures 3 and 4 show a method by which the balls can be removed from the
side of the pedestal, a rectangular recess is cut in the pedestal and a block S is
fitted into it containing the balls. On slightly lifting the carriage the block S
can be withdrawn for the examination of the balls.
Figure 5 shews another method of obtaining ready access to the balls. The
balls are placed under the carriage T, the removable piece T" being fitted in
halves; when it is removed and the carriage slightly lifted the balls are readily
examined.

page_text: This mounting is similar to that shown in Figure 1 in that the training wormı
wheel is secured by a frictional connection to a central pin on the pedestal.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is:
1. A gun mounting of the pedestal type having a central pin projecting upwards
from the pedestal, a training gear wheel mounted on the pin, and a ball bearing
beneath the gear wheel and supporting the carriage, the whole so arranged that
the training gear wheel may be removed and the ball bearing then opened for
the examination of the balls substantially as described in reference to Figure 1
of the drawings.
2. A gun mounting of the pedestal type having the training gear wheel mounted
on and secured by a frictional connection to a central pin on the stem of the
pedestal, such stem receiving the hollow base of the carriage upon it substantially
as described in reference to Figure 1 of the drawings.
3. A gun mounting of the pedestal type in which the shank of the carriage
enters into the pedestal and the carriage is further supported by a pillar passing
up through the shank and a ball bearing at the top of the pillar, the whole being
so arranged that the balls are readily accessible by removing the upper part of
the bearing, substantially as described in reference to Figure 2 of the drawings.
4. A gun mounting of the pedestal type having balls beneath the shank of the
carriage, which balls are held in a block fitting into a lateral recess in the pedestal
and removeable substantially as described in reference to Figures 3 and 4 of the
drawings.
5. A gun mounting of the pedestal type having the hollow base of the carriage
fitting upon the stem of the pedestal and balls between the foot of the carriage
and the pedestal; such balls being retained by a removable piece substantially
as described in reference to Figure 5 of the drawings.
6. Gun mountings substantially as described and shown in the drawings.
