I, THOMAS TURNER, of Fisher Street, Birmingham, in the County of Warwick,
Gunmaker, do hereby declare the nature of this invention to be as follows:-
The object of this invention is to provide a rifle sight elevator, of the type usually
known as a
hanging vernier, capable of easy fixing and unfixing without disturbance
of the record of the elevation last used. I construct my rifle sight elevator in the
following manner.
The vernier scale is raised and lowered by a screw in the ordinary way. Surrounding
this elevating screw is a running nut. The flange of this running nut rests on the
top of the flap of the sight, and forms the abutment by which the elevation is effected.
This running nut sets down tight on to the body of the sight elevator, and the
elevating screw works freely without affecting, or being affected by the same.
When the sight elevator is applied to the flap of the sight, the running nut is screwed
down tight on to the body of the elevator.
The elevating screw is then set to the desired elevation.
The sight elevator is freed from the sight by unscrewing the running nut, without
slackening the elevating screw; and thus, the vernier not being moved, the record of
the last used elevation is not disturbed.
When the sight elevator is again used the running nut is tightened on to the top
of the body of the elevator.

I, THOMAS TURNER, of Fisher Street, Birmingham, in the County of Warwick,
Gunmaker, 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:-
The object of this invention is to provide a rifle sight elevator of the type usually
known as a hanging vernier, capable of easy fixing and unfixing without disturbance
of the record of the elevation last used.
I construct my rifle sight elevator in the following manner.
Fig. I shews a front elevation, and Fig. II a sido elevation of the rifle sight
elevator. The vernier scale a is raised and lowered in the ordinary way by the
screw b. Surrounding the screw 6 is a running nut c, shown separately in Fig. LII.
This running nut is screwed into the top of the body d, and the flange c¹ tightens
on to d.
The screw 6 works freely through the nut c, without affecting, or being
affected by, the said nut.
When the sight elevator is applied to the flap of the sight, the running nut c is
screwed down tight on to the body d. The slide a is then set to the desired elevation
by means of the screw b.
The sight elevator is freed from the sight by slackening the running nut c, without
affecting the slide a or screw b. Thus the record of the elevation is preserved.
When the sight elevator is again used, the running nut is tightened on to the body
of the elevator.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, I declare that what
I claim is :-
:-
A sight elevator with the running nut, as described and illustrated.
