ing the sight carrier and thereafter locking it in
the desired adjusted range position; such adjust
definition is attained by the use of a very thin ap
erture disc which is so mounted in the bore
of the sighting device as to be shielded from most
of the interfering light rays. Peep-sights which
are made from a single piece with a bore drilled
in from each end to secure a thin separating ap
ertured wall are not so commercially possible to
‘ manufacture as to produce the aperture of the
desired precision as is possible to produce and se
cure with an aperture disc made from a separate
piece of very thin metal.
Another object of my invention is to provide
the sighting device with an interchangeable, re
movably mounted, aperture disc so that discs
having apertures of diiîerent diameters may be
readily substituted one for the other.
Another object of my invention resides in the
provision of a firearm sight eye-piece the bore of
which is provided with an oriñce which is com
posed of a multiple of comparatively small planes
each disposed angularly to the adjacent plane;
the oriñce decreasing in diameter inwardly of
' the bore or which oriñce may be progressively de
creased in diameter as by a series of circular steps
decreasing in diameter progressively inwardly of
the sight bore to thereby reduce to a minimum or
40 dissipate reflected interfering light rays to facil
itate visibility and afford sharper definition of
the image of the object viewed therethrough.
A further object of the invention is found in
the provision of a sight eye-piece having a re
movably mounted aperture disc and a removably
mounted aperture disc retainer, which retainer
and aperture disc are adapted to be unscrewed
from the eye-piece and screw-mounted into the
peep-holder or block of a standard sight for use
50 as a small eye-piece to afford unobstructed vision,
as for instance, on a hunting rifle.
A still further object of the invention resides
in the provision of a ñrearm sight having an in
terchangeable plate with indicia thereon which
permit the adjustment of the sight as to eleva
dle which serves as a handle for raising or lower
ing and locking operations being performed by
one hand of the operator.
With the above and other objects in view, my
invention consists in the novel combination, con
struction and arrangement of the parts and
members shown in preferred embodiment in the 20
attached drawing, described in the following spec
ifications and particularly pointed out in the ap
pended claims.
Referring to the drawing:
Fig. 1 is a side elevation of a gun sight embody
ing my invention;
Fig. 2 is a vertical section taken on line 2-2
of Fig. 1;
Fig. 3 is a cross section taken on line 3_3 of
Fig. 2 showing the operating and retaining mem
ber for adjusting the sight as to elevation;
Fig. 4 is an enlarged vertical section taken on
line 4-4 of Fig. 2 showing the improved sighting
eye-piece, and
Figs. 5 and 6 are enlarged perspective views of
the aperture discs.
As shown in the illustrations, the sight com
prises an adapter block I0 of any suitable form
which is adapted for attachment to the side
of the firearm barrel II and on which block is
supported the sight frame I2 by screws I3.
The sight frame I2 is grooved, as at I4, to re
ceive the vertical leg ISA of an L-shaped sight
carrier I5.
'Ijhe horizontal portion or leg 15B of the sight 45
carrier is provided with a depressed channeled
portion I5C for the slidably mounted peep-sight
block I6, a lateral extension IGA of which is cen
trally and longitudinally slotted, as at IEB. The
peep-sight block I6 is slidably adjustable as to
windage within the channel IBC and is adapted to
be securely retained in adjusted position by a
screw I'l mounted in the lateral portion ISB and
extending for adjustable screw connection within

To facilitate and guide the operator in Wind
age adjustment the extension IIìA may be pro
vided with an in-dicator line which is adapted to
register with suitable indications on the hori

The sighting device or peep-sight I8 is formed
with a comparatively enlarged eye-piece I8A hav
ing an exteriorly threaded end connection I 8B
into the slidable block I6 and is provided With a
sight bore I8C which is enlarged inwardly, for
substantially half of its length and threaded as
at IBD to receive an aperture disc retainer I9.
'I‘he aperture disc retainer I9 is provided with
a sight bore I9-^~ adapted to optically register with
the bore I8C of the eye-piece IBA.
The outer portion or orifice I9C of the bore I9A
of the retainer I9 is formed with a multiple of
small planes each disposed angularly to an adja
cent plane, or progressively decreased in diameter
as by a series of circular steps ISB which de

24 is provided with indicia 24B which permits the
adjustment of the sight, with reference to an
indicator 26 (which, in the present instance, is a
part of the frame I2) as to correct elevations
corresponding with predetermined ranges for a
specific or particular type and character of a
bullet, the indicia preferably indicating the
range of the targets in terms of yards. A specific
range plate may be furnished for each specific
type or character of ammunition, so that when 15
the ammunition is changed it is only necessary
to interchange .the used range plate for a range
plate calibrated for the changed ammunition.
The precise position of the range plate may be
corrected and adjusted by loosening the screw 25. 20
When the sight is attached to a riiie, the cor
rect mounting or position of the peep-sight in
relation to that rifle is zeroed once.
This is done
by adjusting the small zeroing screw 21. The
interchangeable range plate is then adjusted to 25
zero position by loosening the screw 25 in the
stud 25A, to permit vertical adjustment of the
range plate. When the range plate for the par

To further enhance the visibility and definition
of the image of the sighted object, I provide an
aperture disc 20 which is made from a very thin

stud 25A is securely aflixed to the range plate by 30
tightening of the screw 25. To change one range

.005 or .007 of an inch, and is provided with an

35 aperture 2|)A in optical alignment or register with
the axes of the sight bores I8C and ISA.
The aperture disc 20 is removably mounted
within the eye-piece I8 between the inner end of
the retainer I9 and the shoulder formed at the
40 enlarged portion of the sight bore, or the inner
end of the retainer I9 may be formed with a
small annular groove to receive the aperture disc.
Being removable, the aperture disc may be inter
changed with any one of several other similar
45 aperture discs of different size apertures, thus
providing a desirable andefûcient sight eye-piece.
The exterior connection threads of the retainer
I9 are such that the retainer I9 and aperture
disc 20 may be readily removed from the eye
50 piece I8 and remounted in the sight block I6 for
use as a small sighting eye-piece.
To conveniently and quickly permit the verti
cal adjustment of the sight as to elevation, the
sight carrier I5 is slidably movable, with its ver
55 tical leg I5A within the stationary frame I2, by
plate for another, when changing ammunition,
carrier leg I5A removed from its support by up
ward movement. The used range plate 24, screw 35
25, and stud 25A may then be removed as a unit
and replaced by a similar unit plate which has
previously been corrected for the ammunition
then to be used. ‘The removed range plate can
thereafter always be properly reinserted into pre 40
determined zeroed position, for use with the par
ticular ammunition for which it was previously
calibrated, by replacing with its attached stud
in the hole provided for it in the vertical leg I5A
of the carrier.
It is obvious that various changes or modifica
tions may be made in the details of construction
or arrangement in the sight as here shown in
preferred embodiment without departing from
the spirit of the invention as defined in the ap
pended claims.
