PROVISIONAL SPECIFICATION.
Improvements in Aperture Sighting-apparatus for Ensuring
Accuracy of Aim with Fire-arms.
I HERBERT PERCY MILLER of 15 Craven Terrace Hyde Park London W. do hereby
declare the nature of this invention to be as follows:-
This Invention has for its object improvements in aperture sighting apparatus,
whereby accuracy of aim is ensured with fire-arms. Such improved apparatus consists
of an opaque plate fitted in a suitable frame and having therein an aperture of about
inch in diameter. A revolving disc is pivoted to such fixed plate which disc is
perforated with groups of holes such groups consisting of one central hole surrounded
by side holes. Aim is taken through the centre hole, the side holes admitting light
to the eye, and thus giving clearer definition of aim, and view of surrounding objects
with less strain on the eye. The groups of holes are made in different sizes to suit
different visions.
Another feature of my invention is that the revolving disc is perforated with single
apertures so that the marksman is enabled to use either the group system or a single
aperture as may be required.
For use either a group or a single aperture may be brought over the larger hole
in fixed plate through which aim is taken.

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 has for its object improvements in aperture sighting apparatus,
whereby accuracy of aim with fire-arms is ensured.
The accompanying drawings show my improvements.
My improvements consist in fitting into a spectacle or other suitable frame an
opaque plate composed either of vulcanite, wood, metal, or like substance, such plato
having therein an aperture of about inch in diameter. Such plate and frame is
marked A in drawing. By means of a thumb piece, marked B, a revolving disc is
pivoted to such plate which disc is perforated with groups of sight holes such groups
consisting of one central hole surrounded by side holes marked C. The side holes
may be round as shown in drawing or they may be in slots radiating from the central
hole, or may be in combination. The revolving disc is perforated with a series of
groups the holes of which groups vary in diameter the marksman is thus enabled to
select any sized hole best suited to his sight and the conditions of light prevailing at
the time. Aim is taken through the central hole, the side apertures admitting light
to the eye, and thus a clearer definition of aim with less strain on the eye is
ensured. Through the side holes, also a better view of surrounding objects can be
obtained.
Another feature of my invention is that the revolving disc is perforated with single
apertures in combination with the group system so that the marksman is enabled to
use either a group or a single aperture as may be desired.
By means of a thumb piece either a group or a single aperture is brought over
the larger hole in fixed plate the apparatus is then ready for aim.
Having now particularly described and ascertained the nature of my said Invention
and in what manner the same is to be performed I declare that what I claim is.
1. Fitting into a suitable frame an opaque plate or disc having therein an aperture
in the manner and for the purpose hereinbefore specified and shown at A.
2. Surrounding a central hole with side apertures such side apertures to be either
round or slots radiating from the central hole substantially in the manner and for
purpose hereinbefore specified at C.
3. Perforating the revolving disc with single apertures in combination with the
group system substantially as shown at C.
4. Making the group holes and slots in varying sizes for the purpose hereinbefore
specified.
5. Making such group system either separately or in combination with each other
as hereinbefore specified.
