COMPLETE SPECIFICATION.
Appliances for Adapting Telescopes for Laying Guns.
I, GEORGE ARTHUR FRENCH, of Shoeburyness in the County of Essex,
Lieutenant Colonel of 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 to means whereby a telescope can readily be mounted on
and adjusted to a gun, so as to facilitate the laying of the gun for firing at a
distant object, as I shall describe referring to the accompanying drawings.
Figs. 1 to 4 inclusive shew the appliance suited for a field gun of existing
pattern;
Figs. 5 to 7 inclusive shew the appliance suited for a muzzle loading rifle gun for
fort service.
Referring first to Figs. 1 to 4, F is the ordinary fore sight and B the back sight;
on these sights I place a bar A which may be of steel, preferably of T section as shewn.
At its one end it has a round hole which drops over the fore sight. At the other end it
is forked, the prongs of the fork resting on the cross head of the back sight, with the
back sight itself projecting up between them. On the bar A are fitted to slide on
the bar longitudinally two supports V and W for a telescope T, these slides being
clamped by screws where required. The hinder support W has its V made of two
separate angle pieces which can be moved transversely by screws, so that the part
of the telescope which lies between them can be a little raised or lowered or moved
a little transversely, to adjust the axis of the telescope to that of the gun. The
front slide V may be made adjustable in like manner. The back sight B being
adjusted as required for range and deflection the bar A and the telescope partake
of the adjustment. Referring now to Figs. 5 to 7 the bar A has a hole in front
with notches as shewn in Fig. 5 by which it can be passed when held in an oblique
position over the ordinary foresight and then can be turned round to line with the
gun, being thus held in front under the shoulder of the foresight. The rear part
of the har A is made with two pins a a which pass into holes bored through the
deflection leaf of the back sight B.
The telescope is in this case adjusted on the bar A in the same manner as for
the field gun.
Although I have shewn appliances for field guns and muzzle loading rifle guns
which have special forms of fore sights and back sights, it is obvious that in other
guns having different forms of these parts, the same mode of mounting and adjusting
a telescope can be applied, the bar and its ends being suited to the sights.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
An appliance for adapting a telescope for laying a gun consisting of a bar fitted
to the sights of the gun and carrying adjustable V supports for the telescope,
substantially as and for the purpose set forth.
