I, EDWIN MICHAEL HALL trading as Osborne and Hall 72, Fleet Street
London, E.C. Gentleman, do hereby declare the nature of this invention to be as
follows:-
My invention relates to improvements in rifle sights particularly applicable to
Martini Henry rifles and has for its object to provide a support therefor which
enables the firer to use the straight bar of the sight piece at any range from 200
to 500 yards and to carry the windage up to 600 yards, there being but a very
little more at the longer range.
In carrying my invention I provide a narrow bar furnished with two or more
holes and carrying at one end a vertical piece composed of two uprights connected
by a cross bar, this piece being formed integrally or hinged to the bar aforesaid.
The flap of the backsight being raised the above support is placed between the
flanges on the block in the hole formed over the spring screw head, the uprights
aforesaid being thus behind the screw head and supporting the flap of the back
sight, resting thereon at a suitable angle varying according as one or the other of
the holes of the above mentioned narrow bar is used.
My improved support may be made of brass, gun metal or of any other suitable
material.

COMPLETE SPECIFICATION.
Improvements in Rifle Sights.
I, EDWIN MICHAEL HALL trading as Osborne & Hall 72 Fleet Street
London, E.C. Gentleman 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 improvements in rifle sights particularly applicable to
Martini Henry rifles, and has for its object to provide a support therefor which
enables the firer to use the straight bar of the sight piece at any range from 200
to 500 yards, and to carry the windage up to 600 yards, there being but a very
little more at the longer range.
In carrying out my invention, I provide a narrow bar furnished with two or
more holes, and carrying at one end a vertical piece, composed of two uprights
connected by a cross bar, this piece being formed integrally with or hinged to the
bar aforesaid. The flap of the back sight being raised the above mentioned
support is placed between the flanges on the block, one of the holes formed in the
support being placed over the spring screw head, the uprights aforesaid being thus
behind the screw head and supporting the flap of the back sight, which rests thereon
at a suitable angle varying according as one or the other of the holes of the above
mentioned narrow bar is used. My improved support may be made of brass, gun
metal or of any other suitable material.
In order that my invention may be more clearly understood, reference is had to
the accompanying sheet of illustrative drawings, in which
Fig. 1 is a plan of the sight without my improved adjustable support,

page_text: Fig. 2 a side and Fig. 3 a front elevation showing the support in position and
Figs. 4 and 5 are respectively a plan and an end elevation of the support detached.
A is the hinged back sight carrying the usual sliding piece B. C is the screw
head serving to hold the adjustable support D, which is provided with two holes E,
either of which can be placed over the screw head, thus keeping it in one of two
positions. This support is composed as shown of a horizontal piece D' and a
vertical piece D' having two projections against which the underside of the hinged
flap rests. As shown in Fig. 2 the flap is arranged for a distance of 300 yards,
the position of the support for 200 yards being shown in the same figure in dotted
lines.
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:-
An adjustable support for the back sights of rifles formed of a horizontal and a
vertical piece D and D, on the top of which the flap A rests and provided with
two or more holes E arranged to fit on to the screw head C substantially as
described and for the purposes specified.
