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 combination gun sights for fire arms; and the object
is to provide a front and a rear sight which when brought into proper alignment
will combine to produce a perfect sight and an unobstructed view of the target
or object so as to secure accurate aim at the moment of firing.
To this end, the invention consists in the construction, combination and
arrangement of the several elements of the device as will be hereinafter fully
described and particularly pointed out in the claims.
In the accompanying drawings, the same reference characters indicate the same
parts of the invention.
Figuro 1 is a perspective view of a rifle barrel with my improved sight applied
thereto;
Figure 2 is an enlarged detail perspective view of the front sight, and
Figure 3 is a similar view of the rear sight.
1 denotes the gun barrel, 2 the front and 3 the rear sight.
The front sight consists of a plate 4, having its approximately parallel
edges 5-5 beveled and slightly tapered to snugly fit a correspondingly formed
transverse recess in the gun barrel.
6 denotes a vertical open frame rising from the plate 4 and formed with an
open arch 7, the centre of which is accurately aligned with the bore of the
barrel.
8 denotes a triangular plate pivoted to the arch of the frame, and the apices
of its angles are formed with graduated visual recesses 9-9--9, by the proper
adjustment of which, the field of vision may be enlarged or reduced as desired.
The rear sight 3 comprises a transverse bar 10 which also has its parallel
edges 11-11 beveled to fit snugly in the corresponding recess in the gun
breech.
The upper edge of the bar 10 is provided with a transverse, semi-circular
recess 12, which is also accurately aligned with the bore of the barrel and with
the axial line of the arch 7 on the front sight 2.
13 denotes a triangular plate pivoted to the bar 10, so that either of the
graduated visual recesses. 14-14-14 may be brought into alignment with the
recess 12, and in such a manner that when the recess in the front sight and
the recess in the rear sight are aligned between the observer's eyes and the target,
the field of vision will be confined to a circle corresponding in size to the adjust-
ment of the visual recesses in the front and rear sights.
In practice, it will be noted that the entire field of vision is unobstructed, there
being no intervening "peep," though the device possesses all the advantages of a
peep sight without its accompanying objections, and therefore the object can be
found easier and with less light.

page_text: Instead of the two sights combining to form a circle, the counterpart trian-
gular plates 8 and 13 may be formed with visual recesses of such shape which
when aligned will combine to form a field of vision, representing any regular or
irregular polygon, the principle involved being a vacuole" or unobstructed
field of vision, and therefore while the accompanying drawing illustrates my
invention in the best form now known to me, it is evident that many changes
in the details may be made within the skill of a good mechanic without depart-
ing from the spirit of the invention, as set forth in the claims at the end of this.
specification.
Having now described and ascertained the nature of said my invention and in
what manner the same is to be performed, I declare that what I claim is :-
1. A gun sight, comprising the front sight 2 and the rear sight 3, substantially
as and for the purpose set forth.
2. A gun sight, comprising the vertical open frame 6. formed with the arch 7;
in combination with the parallel bar 10 formed with the recess 12, substantially
as and for the purpose, set forth.
3. A gun sight, comprising the vertical open frame 6, formed with arch 7
and provided with the revolvable, recessed plate 8; in combination with the..
parallel bar 10 formed with the recess 12, substantially as and for the purpose
set forth.
4. A gun sight, comprising the vertical open frame 6 formed with the arch 7;
in combination with the parallel bar 10 formed with the recess 12, and the
revolvable recessed plate 13, substantially as and for the purpose set forth.
5. A gun sight, comprising the vertical open frame 6 formed with the arch 7,
and provided with the revolvable recessed plate 8; in combination with the
parallel bar 10 formed with the recess 12, and the revolvable recessed plate 13,
substantially as and for the purpose set forth.
