COMPLETE SPECIFICATION.
An Improvement in Sights for Rifles and other Small Arms.
I, ARNULPH MALLOCK, of No. 3 Victoria Street, in the County of London, 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 sights for rifles and other small arms so constructed as to
render the object aimed at and the sight more distinctly visible by telescopically
magnifying and at the same time propeily focussing them.
For this purpose I construct and arrange sights as I shall describe referring to.
the accompanying drawings.
Fig. 1 is a side view of the arm with the sights on it.
Fig. 2 is a section of the sight A in the plane of the axis of the barrel.
Fig. 2 is a transverse section shewing the sight A raised, and Fig. 2B is a
perspective shewing it folded down and presenting the ordinary sight.
Figs. 3 and 3 are views at B similar to Figs. 2 and 24 at A, and Figs. 4, 44
and 4B are views at C similar to Figs. 2, 2A and 2B at A.
Fig. 5 is a diagram illustrating the optical functions of the parts.
The sight A is a lens operating as an object glass; it is hinged to the barrel so
that it can be folded down as shown in Fig. 2B presenting the ordinary fore
sight A' this sight being a V rib formed on the lower part of the frame of A.
The sight B, which is in the principal focus of the lens A, is a rectangular slip
of glass or other transparent material on which are engraved or otherwise marked
a vertical aiming line in the plane of the axis of the barrel and cross lines adapted
for various ranges.
The frame of B is so inade that the transparent slip can be slid out of it so that
another slip with different range marks may be slid into the frame.
This frame is binged to the barrel so that it can be folded down out of the way as
shewn by the dotted lines B' in Fig. 3, when the ordinary sights are used.
C is a rectangular piece cut from a lens which forms the eye lens of the telescope
with B in its principal focus, this lens C acting with the lens at A as a telescope
magnifying the object aimed at, and at the same time making both it and the
sight B properly focussed and distinctly visible.
The eye lens C can be folded down so as to present the ordinary backsight C¹
which is a V groove in a rib projecting from the lower part of the frame of C.
The lens C is made of sufficient height to allow for sighting for the farthest desired
range.
In sighting, the marksman raises or lowers the rifle until he gets the desired
range line on B in coincidence with the image of the object aimed at which is
projected on B by the lens of A.
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 :-
1. Telescopic sights for a rifle or other small arm consisting of a lens for the fore
sight, a transparent slip marked with aiming and range lines for the back sight,
and a rectangular eye lens, arranged and operating substantially as described.

page_text: 2. Mounting the sights and eye lens above referred to so that they can be folded
down when the ordinary sights are to be used, substantially as described.
Dated this 9th day of August 1895.
