PROVISIONAL SPECIFICATION.
A New or Improved Elevation Slide and Wind Gauge Combined, to
be Affixed to the Flap of Backsight of Martini Henri and other
Rifles and Carbines.
JOHN HERBERT HEAD, Carpenter 3 Victoria Terrace, Ringwood Hants. do
hereby declare the nature of this invention to be as follows:-
This invention relates to the construction of the elevation slide which is affixed
to Martini Henri and other rifles and carbines, being made in two distinct and
separate pieces. The V or sighting slide is grooved to allow of the same being
moved from right to left, or vice versa, on the elevation slide thus allowing the
marksman to move the same in either direction, according to windage required
which enables the marksman to take his sight through the V of sliding bar (or
with bar reversed) on to foresight of rifle, and in a direct line with the bullseye,
instead of aiming off the object which it is the intention of the marksman to hit.
In order that the marksman may determine the allowance of windage, lines are
made on the elevation slide, to which one centre line on the V or sighting slide is
made to correspond.

COMPLETE SPECIFICATION.
A New or Improved Elevation Slide and Wind Gauge Combined, to
be Affixed to the Flap of Backsight of Martini Henri and other
Rifles and Carbines.
JOHN HERBERT HEAD Carpenter 3 Victoria Terrace Ringwood Hants. 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 construction of the elevation slide which is affixed
to the flap of backsight of Martini Henri and other rifles and carbines. My
invention being made in two distinct and separate pieces which when put together
and placed on the back flap exactly resembles those at present in use. The Vor
sighting slide is grooved to allow of the same being moved from right to left or
vice versa on the elevation slide thus allowing the marksman to move the same in
either direction according to windage required, the moving of which enables the
marksman to always take his sight through the V of sliding bar or from centre
line with bar reversed on to foresight of rifle and in a direct line with the bulls-
eye instead of aiming off the object which it is the intention of the marksman to
hit. The sliding bar is marked with one perpendicular line in the centre.
The Vor sighting slide is marked with perpendicular lines at intervals to
represent degrees of wind, which slide can be moved in either direction to
correspond exactly with the centre line on sliding bar.
In order that my invention may be fully understood I beg to refer to the
accompanying drawings.
Fig. 1 represents a full front view of my invention, as applied to flap of back-
sight and shews the position of the V or sighting slide adjusted to the centre line
of elevation slide when no windage is required.
Fig. 2 represents a full front view with sighting slide moved to the left to the
full extent.
This sighting slide can be adjusted to any line on the elevation
Prine Rd1

thumb.
Fig. 3 shews the side section of backflap with elevation slide affixed, the dotted
lines the end section of the front bar of elevation slide.
Fig. 4 represents front view of V or sighting slide separated from the elevation
slide.
Fig. 5 represents front view of elevation slide separated from the V or sighting
slide, the outer lines shewing the back part and the inner lines the front.
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
1. An elevation slide in two parts working in combination from right to left or
left to right as shewn in Fig. 2.
2. A Vor sighting slide grooved as shewn in Fig. 4 to allow the front har of
elevation slide as shewn in Fig. 5 to fit and work in the same.
3. Perpendicular lines marked at intervals on the front bar of elevation slide as
shewn in Fig. 5 to either of which lines the centre line on V or sighting slide can
be adjusted.
4. The back part of the elevation slide having a bar continuing right across the
backflap.
