Improvements in Mountings or Stands for Quick-firing or other
Guns, or for Astronomical or Terrestrial Instruments.
I, ANDREW HUGH BOGLE of 4 Park Place, St. James' in the County of
London, Major General late Royal Artillery, do hereby declare the nature of this
iuvention to be as follows:-
My invention relates primarily to that class of gun mountings or stands known as
"Tripod Mountings" and which for machine guns have to a great extent superseded
the more heavy and cumbersome cone mounting, the latter however being still
largely employed in connection with quick firing guns, and the invention consists
in various improvements designed with a view to produce a three, or more, legged
mounting, whether for quick firing or other guns which shall be lighter and more
compact when folded up than either the tripod or cone mountings now in use, and
of any required strength. The tripod mounting as at present constructed for
machine guns, consists essentially of a metal centre piece to which three metal legs
are connected with ordinary pivot joints. On the upper side of the centre piece
is an upright pintle on which the gun revolves or a socket to receive the gun
carriage and on the under side is a directing rod projecting downwards on which
slides a collar. The legs are connected by means of stays at a certain point of
their length to this collar by means of ordinary pivot joints, so that when the legs
are opened to their normal extent the collar slides down the rod but is prevented
from sliding off by means of a flange or stop thereon. When the collar comes
against the stop the legs are prevented from opening further and are in their
normal position. This rod however prevents the legs from closing up compactly
when it is necessary to transport the apparatus on a saddle, or say from a ship to a
boat or from a boat to the shore; and further should either of the stays be shot
away there is nothing to prevent the corresponding leg from opening further out
and so putting the gun out of action.
Now in my improved mounting I do away with the downwardly projecting rod
altogether and I bring the ends of the steel stays from the legs to a movable block
or piece of metal that I call a centre resistance piece and to which I pivot the
inner ends of the stays with a stop joint which limits the action of the resistance
piece in a downward direction; thus this resistance piece performs the functions of
the downwardly projecting rod without its weight a great advantage as regards
transport while less space is occupied when the legs are folded up. The outer ends
of the stays are pivoted to the legs preferably by similar stop joints.
I preferably make the legs of steel tubes which are stronger, more elastic,
cheaper and weigh less than the metal tubes hitherto employed. These steel tubes
may be filled with wood and have rivetted or otherwise secured to their upper end
brass lugs which form a joint to connect the legs to the centre piece. This joint is
also a stop joint, so that the legs cannot open beyond a certain angle, even without
the use of the stays; therefore should the stays be shot away or otherwise disabled,
the mounting is still efficient for service. The stop or limit of the joints at the
upper ends of the legs should come into play at the same time as the joints in the
corresponding stays.
The use of the centre piece in place of the downwardly projecting rod also
allows the legs to fold closer together, thus forming a more compact article for
transnort.

other guns it is also applicable to stands or mountings for astronomical and
terrestrial instruments.

Improvements in Mountings or Stands for Quick-firing or other
Guns, or for Astronomical or Terrestrial Instruments.
I, ANDREW HUGH BOGLE of 4 Park Place, St. James' in the County of
London, Major General late Royal Artillery, 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 :-

My invention relates primarily to that class of gun mountings or stands known
as Tripod Mountings and which for machine guns have to a great extent
superseded the more heavy and cumbersome cone mounting, the latter however
being still largely employed in connection with quick firing guns; and the invention
consists in various improvements designed with a view to produce a three, or more,
legged mounting, whether for quick firing or cther guns which shall be lighter and
more compact when folded up than either the tripod or cone mountings now in use,
and of any required strength. The tripod mounting as at present constructed
for machine guns consists essentially of a metal centre piece to which three metal
legs are connected with ordinary pivot joints. On the upper side of the centre
piece is an upright pintle on which the gun revolves or a socket to receive the gun
carriage, and on the under side is a directing rod projecting downwards on which
slides a collar. The legs are connected by means of stays at a certain point of
their length to this collar by means of ordinary pivot joints, so that when the legs
are opened to their normal extent the collar slides down the rod but is prevented
from sliding off by means of a flange or stop thereou. When the collar comes
against the stop the legs are prevented from opening further and are in their
normal position. This rod however prevents the legs from closing up compactly
when it is necessary to transport the apparatus on a saddle, or say from a ship to a
boat or from a boat to the shore; and further should either of the stays be shot
away there is nothing to prevent the corresponding leg from opening further out
and so putting the gun out of action.
Now in my improved mounting I do away with the downwardly projecting rod
altogether and I bring the ends of the steel stays from the legs to a movable block
or piece of metal that I call a centre resistance piece, and to which I pivot the
inner ends of the stays with a stop joint which limits the action of the resistance
piece in a downward direction, thus this resistance piece performs the functions of
the downwardly projecting rod without its weight, a great advantage as regards
transport, while less space is occupied when the legs are folded up. The outer
ends of the stays may be connected to the legs by similar stop joints.
I preferably make the legs of steel tubes which are stronger, more elastic,
cheaper and weigh less, than the metal tubes hitherto employed. These steel tubes
may be filled with wood and have rivetted or otherwise secured to their upper end
brass lugs which form a joint to connect the legs to the centre piece. This joint is
also a stop joint, so that the legs cannot open beyond a certain angle, even without
the use of the stays; therefore should the stays be shot away or otherwise
disabled, the mounting is still efficient for service.

page_text: The stop or limit of the joints at the upper ends of the legs should come into
play at the same time as the joints in the corresponding stays.
The use of the centre piece in place of the downwardly projecting rod also
allows the legs to fold closer together, thus forming a more compact article for
transport.
In order that my invention may be better understood I will proceed to describe
the same as applied to a mounting or stand for guns.
Figure 1 is an elevation of a gun-stand constructed according to my invention.
Figure 2 shows the said gun-stand closed up.
Figure 3 is a plan.
The gun-stand shown is a tripod, the legs a of which are composed of steel or
other suitable material preferably tubular, The legs a are provided at their upper
ends with lugs b which are connected with or jointed to lugs c on the centre piece d
by the pins e.
The ends of the lugs bare so shaped as to form a stop by coming
or butting against the centre piece d when the legs are opened to the maximum
limit. Consequently the gun-stand or mounting will be effective for service even
if the stays (about to be described) are shot away or otherwise damaged. The
stop action of the lugs b should come into action simultaneously with the stop action
of the stays.
The
The legs a are provided with stays the inner ends of which are jointed to a
movable block or piece of metal g which I call the centre resistance piece.
inner ends of the stays f are so shaped as to form stops by coming or butting
against the piece g and thereby limiting the downward movement of the centre
resistance piece g at the required point.
The form of the inner ends of the stays f and of the lugs b whereby they act as
stops is shown in the figures. The outer end of the stays f may be pivotted to the
legs by similar acting joints.
Although my invention was primarily designed for mountings for machine or
other guns it is also applicable to stands or mountings for astronomical and
terrestrial instruments.
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. In mountings or stands for guns and other purposes a movable centre
resistance piece or block in combination with stays connecting the legs of the
stand to the said block the joints between the stays and the block being stop joints,
substantially as and for the purposes described.
2. In mountings or stands for guns and other purposes the combination with a
movable centre resistance piece or block and with stays furnished at their inner
ends with stop joints as set forth, of stop joints between the upper ends of the
legs and the main or fixed centre piece, substantially as and for the purposes
described.
3. The improved mounting or stand as described and shown in the accompanying
drawings.
