A RIFLE VERNIER
Year: 1885

page_text: I, HARRY GREENER of The Prize Gun Works St Mary's Square Birmingham,
in the County of Warwick, a Gunmaker do hereby declare the nature of my
invention for A RIFLE VERNIER to be as follows:-
The formation of an instrument to correctly mark the sights of Rifles, by means
of an addition to the ordinary Rifle Vernier elevator.
The object obtained by my invention is the marking of the leaf of the rifle sight
to allow for windage or drift, or to determine the true centre.
I get the line correctly perpendicular and parallel to the standards of the sight-
tangent, by utilising the standards of the sight as a bearer or basis for the formation
of the line.
I construct a projection on the ordinary Vernier elevator at right angles to the
standards or body, and into this projection I fix a metal marker,-or construct it
so as to permit of any pencil or brush being used to mark.
The sliding Bar of the Vernier with its lip on the upright of the sight-tangent
as a guide, is moved by the elevating screw until the required amount of deviation
or the true centre is read off, the Vernier-elevator being then slipped along the
sight tangent, the lip of the sliding Bar still guided by the sight tangent standard,
a true and correct line is marked on the leaf of the sight by the metal or other
marker fixed into the projection.
For facilitating the reading off of the Vernier, I mark the scale upon the outside
of the flange of the Vernier uprights, and back of the sliding Bar.

page_text: I, HARRY GREENER, of The Prize Gun Works St Mary's Square Birmingham
in the County of Warwick, Gunmaker do hereby declare the nature of my
invention for RIFLE VERNIER and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement
The addition of an arm fixed at right angles to the standards of the ordinary
Vernier elevator. This arm furnished with a point or pointed pin for the purpose
of scratching upon the bar of a rifle sight and leaving a distinctly marked line.
The elevating bar of the Vernier elevator is used as a basis for the scale marked
upon the face of the rifle marker.
In Fig. 1 the Rifle sight marker is shown actual size, at right angles to the
standards A, A, the arm B is fixed, this arm is furnished with a pointed pin C.
The elevating bar a, a, is used as the basis for the Vernier scale marked upon it
and on the standards A, A.
The position of the projecting arm B may be varied so as to adapt it to any
existing. vernier elevator or to any special form of sight, or as found convenient to
manufacture.
Figs. 2, & 3, shew the arm B in other positions on the standards A, A.
The method of applying my invention is shewn in Fig. 4.
D is the Rifle sight, E, E, the bar to be marked, the standards F F of the
tangent of the sight are used as the base for affixing the marker. The marker is
brought into contact with the sight having the standards A, A, of the marker at
right angles to the standards F, F, of the sight tangent. The elevating bar a, a, is
brought into contact with the edge of one of the standards F, and the scale of the
Vernier read off and the marker adjusted in accordance there with. On the Vernier
marker being moved in a line with the standards F F the pointed pin or pointed
arm of B marks on the bar E E the line required.
Having now particularly described and ascertained the nature of my said
declare that
invention, and in what manner the same is to be performed,
what I claim is
1. The construction of a Vernier sight marker with the arm B for the purpose
herein before set forth and described.
2. The method of combining the elevating bar, a, and the Vernier scale on the
face of the Vernier elevator for the purpose hereinbefore set forth and described.
3. The pointed pin C affixed to a Vernier elevator for the purpose of marking the
bar of a rifle sight.
