PROVISIONAL SPECIFICATION.
Improvements in Orthoptic Frames.
I, MATTHEW MULLINEUX, Cartridge Maker, 17 Maple Street, Cheetham,
Manchester, do hereby declare the nature of this invention to be as follows:-
This invention relates to orthoptic frames, its object being to keep the orthoptic
in a fixed position..
It is well known that orthoptics are a great help to accurate rifle shooting, but
owing to the difficulty of keeping them fixed in one position, they are discarded by
many marksmen. The unsteady nature of orthoptic frames as at present made,
renders it necessary for the marksman to adjust his orthoptic after each shot, and
this often leads to his taking false sights. To obviate this, I place a nose-cap of
wire, brass, or other hard substance, on the frame of the orthoptic. This nose-cap
can be made to any size, and when fastened to the orthoptic frame, enables the
marksman to fix his orthoptic securely, and complete his shooting without further
trouble. The nose-cap fits the bridge of the nose, and keeps the orthoptic in one
position. It can be made suitable either for prone shooting or shooting from the
back.
Dated this First day of September 1892.

COMPLETE SPECIFICATION.
Improvements in Orthoptic Frames.
I, MATTHEW MULLINEUX, Cartridge Maker, of 17 Maple Street Cheetham,
Manchester, 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 the frames of orthoptics used in shooting. It is
absolutely necessary to good shooting that the aperture in the orthoptic should be
opposite the sight when the marksman is in shooting position; and that the exact
same relative position of eye and aperture should be maintained. throughout. The
frames hitherto used have rested on the nose by a frame usually made of a single
wire; but this required frequent adjustment at each shot, and there was no certainty
that the relative position of eye and aperture was the same each time. In my
improved frame I place a piece of thin sheet brass, steel, or other metal shaped to
fit the bridge of the nose and covering the nose about a half or one third its length;
the size, however, may be varied according to the requirements of the wearer. This
I call the nose-cap, and it is fixed on the wire frame in such a position that it fits
the nose exactly and keeps the orthoptic vertical when the marksman is in position.
For greater comfort, I line the inside of the nose-cap with soft leather. The nose-
cap fitting the nose exactly, as it does, keeps the orthoptic securely in the exact
same position, and preserves the relative positions of the aperture and the eye
throughout. When once-adjusted, therefore, the marksman is saved the trouble and
anxiety he formerly experienced in readjusting after each shot.
As it is necessary
that the orthoptic be vertical when the marksman is in position, the nose-cap for
what is known as the back position is placed at a different angle to the orthoptic to
bring about this effect.

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 :
The construction of orthoptic frames with nose-caps for the purpose of keeping
the orthoptic in a fixed position, substantially as hereinbefore described.
