Improvements in Sights for Fire-arms.
We, JOSEPH MANTON, of 499 Craig Street, Gun Maker, and CHARLES CARTER
NEWTON, of 441 St. Urbin Street, Gentleman, both in the City of Montreal, in the
District of Montreal, and Province of Quebec, Canada, 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 sights for rifles and other fire-arms, in which the "elevating
sliding bar" by which the elevation is adjusted for range, is also made adjustabl
laterally to allow for wind as we will describe referring to the accompanying
drawings.
Figure 1 is a side elevation of an ordinary military sight with our invention
applied thereto. Fig. 2 is a front elevation. Figs. 3 to 10 inclusive shew details of
construction.
a is the block fixed on the barrel, and hinged to it at b is the upright frame C, these
parts being of ordinary construction.
According to our invention we fit a block d to slide rather tightly between the two
sides c c of the frame c which are made truly parallel. The block d has flanges e and
a dovetail projection f fitting the groove g of a cross bar which cross bar is provided
with an ordinary V shaped sight and sight lines k. By sliding the block d up and
down, the height of the bar h may be adjusted as usual for range, while the bar h
may be set transversely, as indicated by the dotted lines in Fig. 2, to allow for wind.
is a small screw inserted in the bar h (see Fig. 5) to prevent it from being pushed
off the projection f.
The section shown in Fig. 6 is taken at the line a Fig. 3, and the section shown in
Fig. 7, is taken on line y Fig. 5.
On the top (as shown in Fig. 3) and on the bottom (as shown in Fig. 4) of the
bar h, if desired, scales m may be marked; their zero marks n coinciding with the
inner edges of the uprights c'e', when the sight i is in the middle. By the scales m,
the lateral deviation may be adjusted with great accuracy.
As shown in Fig. 6, a small set screw o may be screwed into a hole p in the block d
to bear against the bar and tighten it on the projection f.

Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
1. In sights for fire arms the combination of a bar provided with ordinary sights
and marks, also having a dovetailed groove; a block having a dovetailed projection
arranged to fit the dovetailed groove of the said bar, the same being so arranged
that the said bar may slide transversely upon the said dovetailed projection; uprights ¹¹
arranged to form a guide to the said block, in its. vertical movement, the. whole
substantially as described.
2. In sights for fire arms the combination of the uprights c¹ c', block d arranged
to slide between and be guided by the said uprights and provides with a dovetailed
projection, and flanges e bar provided with dovetailed groove g,.fitted to slide on
the dovetailed projection f, the whole substantially as described.
3. In sights for fire arms the combination of the uprights c¹ c', block d arranged
to slide between the said uprights and provided with a dovetailed projection f.and
flanges e, also having set screw o with bar h having groove g arranged to slide upon
the projection f, the whole substantially as described.
