We, ARTHUR TREVOR DAWSON, GEORGE THOMAS BUCKHAM, and CARL ALFRED
LARSSON, all of Vickers, Sons & Maxim Limited, of No. 32, Victoria Street,
Westminster, in the County of London, do hereby declare the nature of this
invention to be as follows:-
This invention relates to a light portable all round fire mounting for a
machine gun so arranged that it can be at once converted from firing to port-
able condition without dismounting the gun, and then two men can comfortably
carry the gun and mounting a considerable distance over ground impassable
for a wheeled carriage.
The trunnions rest in bearings in a fork head, the trunnions and bearings
being so arranged that on withdrawing a spring bolt passing through a tube,
a head and nut of which constitute the trunnions proper, these can be raised
out of the bearings through a forwardly inclined gap, and the gun can thus
be readily removed from the mounting.
The gun can be held at any desired elevation by a wedge which passes
through the fork head and is connected to a lever handle within reach of the
gunner at the rear of the gun. The fork head to which the ammunition box
is attached so as to revolve with it, turns upon a pivot on an inverted fork,
and the pivot bearing is provided with a clamping screw and handle to hold
the gun trained in any desired direction.
In the limbs of the inverted fork are pivotted two pairs of legs the ends of
which are made as flat shoes with spikes to prevent slipping on hard ground.
The two legs of each pair spread out from a socket -which is pivotted in the
limbs of the inverted fork and has an arm projecting upwards.
These two arms which cross each other side by side have through them holes,
one of them being slotted. A clamping bolt passes through these holes and
through circularly slotted holes in the cheeks of the inverted fork.
When the gun is in use the arms are clamped in such position that both
pairs of legs extend obliquely to the ground.
When the gun has to be carried, they are clamped in such position that the
legs extend horizontally the one pair to the front, the other pair to the rear,
cach pair in position to be carried by the hands of one man,

page_text: Westminster, 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 a light portable all round fire mounting for a
machine gun so arranged that it can be at once converted from firing to port-
able condition without dismounting the gun, and then two men can comfortably
carry the gun and mounting a considerable distance over ground impassable
for a wheeled carriage.
Fig. 1 of the accompanying drawings is a side view of a gun and mounting
according to this invention in condition for firing.
Fig. 2 is a side view of the gun and mounting in condition for being carried.
Fig. is a plan of the upper part of the mounting.
Fig. 4 is an end view of the upper part of the mounting with ammunition
box.
Fig. 5 is a side view shewing the legs folded together.
Fig. 6 is a transverse section shewing the trunnions and their sleeve.
Fig. 7 is a plan partly sectional of the upper part of the mounting.
t
The trunnions rest in bearings in a fork head a the trunnions and bearings
being so arranged as shewn in Fig. 6, so that on drawing back a spring bolt b
which passes through a sleeve and has a head d and a cap e which constitute
the trunnions proper, these can be raised out of the bearings in a through a
forwardly inclined gap, and the gun can thus be readily removed from the
mounting. The gun. can be held at any desired elevation by a. wedge f which
passes through the fork head a and has a handle y within reach of the gunner
at the rear of the gun. The fork head a to which the ammunition box h is
attached, so as to revolve with it, turns upon a pivot i on an inverted fork j
and the pivot bearing is provided with a clamping screw and handle & to hold
the gun trained in any desired direction.
and
In the limbs of the inverted fork are pivotted two pairs of legs, the one
pair and the other pair m the ends of which are made as flat shoes n with
spikes to prevent slipping on hard ground. The two legs of each pair spread
out from a socket which is pivotted in the limbs of the inverted fork
has an arm projecting upwards from the socket of the legs 1, and t from the
socket of the legs m. These two arms and t cross each other side by side.
The arm has a slot o partly straight and partly curved in which is engaged
a pin p projecting laterally from the arm s. When this pin p is in the straight
part of the slot o a pin g is passed through it and through holes in the cheeks
of the inverted fork the arms s and t being thus held in such position that
both pairs of legs and m extend obliquely to the ground as shewn in Fig. 1.
When the gun has to be carried the legs 7 and m and their arms and t are
moved to the position shewn in Fig. 2, the legs extending horizontally, the one
pair m to the front, the other pair to the rear, each pair in position to be
carried by the hands of one man. In this case the pin is put through lower
holes in the cherks of j.
Through the arms projecting up from the legs there is another hole r
through which the pin g is passed to hold the legs in the position shewn in
Fig. 5, suitable for being carried against the shoulder.
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 mounting for a machine gun comprising a pair of removable trunnions in
gapped bearings in the limits of a fork, an inverted fork in which the trunnion
fork is pivotted, and to which are pivotted a pair of sockets having each a pair of
legs projecting obliquely from them, arms of these sockets arranged side by
side between the cheeks of the inverted fork, the one arm having a laterally

page_text: projecting pin engaged in a curved slot in the other arm, and a removeable
pin for holding the arms and legs in any one of three positions, substantially
as and for the purpose set forth.
