port a standard .50 caliber machine gun, but it is
to be understood that a mount for any relatively
heavy caliber gun may be substituted therefor.
As shown, the mount consists of a pair of side
plates 56 and 57 each extending from the mem

here shown a bracket member ‘I0 which is sup
ported on the upper end of the main standard 69
as by a tapered roller bearing ‘II so that the
bracket ‘I0 is rotatable relative to the standard
sion 62. ‘The front end of the extension 62 is
provided with a pin 63 which is journaled within
an end of a shaft or rod 64 so as to support the
same, and at the same time permit the rotation
of the rod 64 relative to the pin 63. The rod 64
is connected by means of a turnbuckle Bria with
a second rod 65 which is rotatably connected to
the forward end of the base plate II for the 10
pointing piece previously described.
It is to be understood that the connection of
the rod 65 and the base plate II is similar to the
connection of the portion 62 and the rod 64 so
that the rod 65 is capable of rotation relative to
the base plate II.
It is evident that by turning the turnbuckle
64a the forward end of the plate II and the for
ward end 62 of the plate (H can be ‘brought closer
together or moved farther apart.

of side plates ‘I8 and ‘I9 similar to the plates 56
