This invention relates to ordnance mounts and
more particularly to a mount for a plurality of
machine guns.
v I

As herein illustrated the inven-‘_
tion is shown as embodied in a mount‘ for two
.50 caliber Browning machine guns, but it'_:is' to
be understood that the invention is of broader
utility and may be used with other makes of guns
or in mounts for more or less than two guns.
Machine guns of the type above mentioned are
commonly provided near their back ends with a
pair of apertured ears and near their front ends
with a pair of oppositely disposed threaded at
taching bosses which are used for securing the
guns to an adaptor or equivalent supporting
structure.
Objects of this invention are to pro.
vide a novel and improved gun mount for accom
modating machine guns of this type in which the
guns can be readily installed and which are so
arranged that adjustments for bore-sighting are

these ends in view, and in accordance withv a
feature of this invention, the adaptor is provided
with separate mounting means for cooperating
with the threaded attaching bosses at the front
end of a machine gun and with the apertured
ears at its back end to support it on the adaptor,
each of the supporting means being adapted for
ready attachment to the aforementioned parts of
the gun and capable of imparting adjusting move

threaded bores I I0, H0 in which are mounted
bored externally threaded gun-adjusting screws
H2, H2 and ?tted within these screws are gun
clamping screws H4, H4, each having an inner
end H6, threaded into a boss 56 of the recoil
sleeve, and a head I H which bears against the
outer end- of a gun-adjusting screw H2.

the. gun is next made secure by turning the gun
adjusting. screws H2, H2 down against the faces
: of the bosses 56, 56, tightening the lock nuts H6,
H8, and ?nally tightening the gun-clamping
screws H4, H4.
Bore-sighting adjustments of the guns are
made in the‘ following manner.
To adjust a gun
in elevation, the gun-clamping screws H4, H4
and lock nuts I I8, I I8 are first loosened and then,
by suitable turning of the gun-adjusting screws
H2, the front end of the gun may be raised or
lowered until the desired sighting in elevation is
obtained, whereupon the lock nuts H8 are again

tightened. During this adjustment the gun pivots
at its rearmost end on the trunnion shaft 90 and
the yoke 36 turns slightly in the bushing 30
enough to accommodate itself to the higher or
lower position of the front end of the gun and
to avoid binding of the gun-adjusting and gun
clamping screws. In adjusting a gun in azimuth,
the gun-clamping screws H4, H4 and nuts ‘72
and ‘I4 are loosened and the lateral position of
the back end of the gun is changed by sliding ,
the carriage 62 along on the crossbar 50 until
the desired sighting in azimuth is obtained. To
facilitate this adjustment the stop screw I 26 may
be employed in the following manner. With the
lock nut I22 loosened this stop screw is backed
off away from the end of the crossbar?? and a
rough adjustment of the back end of the gun in
azimuth is made. The screw I20 is now turned
until its end touches the end of the crossbar 56,
after which the continued turning of the screw
in one direction or another, while its end is held
against the crossbar I56 by inward pressure
against the carriage 62, will give a fine adjust
