Improvements in Sights for Fire Arms.
I, JAMES WOOD CARVER, of Pawlet, in the County of Rutland, and State of
Vermont, United States of America, Gentleman, do hereby declare the nature of this
invention to be as follows:-
My Invention relates to a sight to be attached to the stock of any ordinary riflė or
fire arm; which is characterized by the following features-vizt. it is hinged so that
it may be turned down out of the way when not in use and when in use may be held
vertically regardless of the inclination of the base of the sight upon the stock of the
fire-arm; it is capable of lateral adjustment to make allowance for the wind and may
be raised or lowered; its peep-hole is in the form of a tubular screw which may be
changed according to the size of peep-hole required; and it comprises an adjustable
shield by means of which the marksman may shoot accurately notwithstanding both
eyes are kept open when shooting.
The base of the sight is screwed to the stock, there being a longitudinal recessed
slot in the base for the reception of the head of one of the screws, so that the screw-
head is below the upper surface of the base, and the opposite faces of the slot are
grooved longitudinally for the reception of a sliding cover with which it is provided.
The frame of the sight is hinged between lugs, to a screw upon which it may be
swung up and down and which may be tightened to hold the frame with sufficient
rigidity. Or, the lower rounded portion of the frame through which the pivot pin
passes, may be grooved for the engagement of a spring on a transverse slide. The
grooves are slightly bevelled or of V shape, so that the spring will hold the frame
in any position in which it may be set. This construction admits of the frame being
turned up vertically and held regardless of the inclination of the base of the stock of
the fire-arm.
screw,
The frame is furnished with a vertical adjusting screw whose head projects
above the top of the frame. In the inner edge of the frame is a groove
for the reception of this screw, the groove being about half the diameter of the
so that this screw is partly received in the groove and the sight is
carried by a block placed within the frame and having a semi-circular threaded
groove corresponding to the screw, so that by rotating the screw the sight may be
raised or lowered at will, a scale being provided so that the sight may be accurately
adjusted to suit different ranges. Through the sight there is a central hole and a
tubular screw, constituting the peep-hole, passes through the block and screws into
the sight for clamping and holding the same to the frame, the parts being loosened so
as to be raised or lowered by partially rotating the sight, the tubular screw remaining
stationary. The face of the sight is plain, the head of the screw being in the rear,
and the screw is changeable so that any size peep hole may be made use of. The open
sight is in the form of a plate which hangs from the tubular screw and it is notched
as usual, and provided with a pointer working over the scale in the frame. There is
a slot in its upper part, so that may be pushed up behind the other sight when
desired. The sight may be adjusted laterally by connecting the lugs on which it is
supported to a transverse slide contained in a groove on the base piece and having a
nut through which extends a screw having a head by which it may be rotated. The

page_text: base would preferably be provided with an index or scale, and the slide with a
pointer.
The adjustable shield is for the purpose of providing for the difficulty experienced by
some marksmen in looking steadily at the object aimed at, with one eye while keeping
the other eye shut. The shield is supported by a block in vertical bars which are in
one with lateral extensions which are screwed to the frame of the sight, said block
being provided with a screw whereby the shield can be set to the same height as the
sight itself, while it can also be adjusted laterally.

Improvements in Sights for Fire Arms.
1, JAMES WOOD CARVER, of Pawlet, in the County of Rutland and State of
Vermont, United States of America, 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 :-
This Invention relates to a sight which is adapted to be attached upon the stock of
any ordinary rifle or fire arm and it is hinged so that it may be turned down out of
the way when not in use or turned up vertically and held by the spring, regardless
of the inclination of the base of the sight upon the stock of the fire arm; and 1
provide for adjusting the sight laterally to make allowance for the action of the wind
upon the bullet, and the sight itself can be raised or lowered in the hinged frame or
leaf by a vertical screw, and the sight itself is attached by a tubular screw forming
the peep-hole which screw is changeable for different sizes of peep-holes, and I
provide a shield which can be raised or lowered to correspond in height to the sight,
and it can be moved laterally so that such shield allows the marksman to keep both
eyes open, the shield preventing the mark being seen by the left eye, the sight being
taken by the right eye or the reverse; and my special features of improvement
relate to the construction and combination of devices hereinafter set forth.
Referring to the accompanying drawings, figure 1 is a vertical longitudinal section
of the sight turned up in position for use; Figure 2 is an elevation from the rear,
with the base in section; Figure 3 is a sectional plan at the line figure 1;
Figures 4 and 5 are views representing slight modifications in the base piece; and
figure 6 is a section at the line y-y figure 1.
The base A is to be attached to the stock of the gun by the two screws 2 and 3 and
there is in the base a longitudinal slot for the reception of the screw 3, said slot being
recessed so that the head of the screw is below the top surface of the base A and
the opposite faces of the slot are grooved longitudinally for the reception of the
sliding cover B. The frame or leaf is provided at its lower end with a knuckle 5
forming part of the hinge upon which the sight can be swung up or down. This
knuckle 5 is received between the joint pieces 6 6 and there is a screw D through
the central holes of these pieces 5 and 6 so as to form a hinge for the frame or leaf
of the sight, and by tightening this screw D the necessary friction is applied to
the ends of the knuckle 5; but it is preferable to make in this knuckle 5, small
longitudinal grooves and to screw upon the sliding cover or transverse slide I a small
spring 7 the straight or V-shaped end of which enters one of these grooves and
these grooves should be slightly bevelled or V-shaped, similar to ratchet teeth, so that
this spring 7 will hold the frame C in any position in which it may be turned;
and this construction allows for the frame being turned up vertically and held
by the end of the spring 7 regardless of the inclination of the base A upon the stock
of the fire arm.
Within the frame C is the vertical adjusting screw E having the head 8 above the
top of the frame C, and there is a groove along the inner edge of this frame C at

page_text: one side about half the diameter of the screw E so that one side of this screw E is
received into this groove and the other side of the screw projects, and there is a
block F within the frame Chaving at one edge the semi-circular threaded groove
corresponding to the screw E, so that by rotating this screw E the block F can be
raised or lowered to any desired point, and there is upon the frame C a scale
indicating, by the main divisions, ranges of one hundred yards each and the small
intermediate divisions indicate twenty-five, fifty, and seventy-five yard ranges, and
these may be numbered if desired so that the block F and the sight G, which is
carried by the same, can be raised or lowered to adapt the same to the distance of
the target or other object fired at. Through this sight G is a central hole and the
tubular screw 10 passes through the block F and screws into the sight G for clamping
and holding the same to the frame C and the parts are loosened so as to be easily
raised or lowered by partially rotating the sight G, the screw 10 remaining
stationary. This screw 10 being tubular, forms the peep hole of the sight and the
face of the sight is plain, the head of the screw being in the rear, and this screw is
changeable so that any desired size of hole through the tubular screw may be made
use of, thus changing the size of the peep hole by removing one screw and substituting
another. The open sight H is in the form of a plate that hangs from the screw 10
and it is notched as usual in open sights, but it may be pushed up behind the sight G
when desired, there being a slot in the upper part of this open sight for the passage of
the screw 10 and at one edge of this open sight is a pointer or index for denoting the
range by the scale or divisions upon the face of the frame C.
I provide for adjusting the sight laterally to adapt the same to shooting when the
bullet is liable to be influenced by lateral currents of wind. To provide for this
adjustment, I connect the joint-pieces 6 to the transverse slide I that is within the
groove running across the base piece A and below this transverse slide the nut 18
projects down into the opening in the base A and the screw K passes across the base
and through this nut 18 and the screw has a head at one end so that it can easily be
rotated by hand and in so doing the slide I is moved laterally one way or the other
across the base A and the vertical axial line of the sight to the right or to the left, as
may be necessary in adjusting such sight to allow for the action of the wind upon the
ball. The modifications shewn in figures 4 and 5 correspond to the devices shewn in
figures 1, 2, 3, except that in figure 5 the V portions are transposed, and the index, in
one case, is above the pointer and in the other case it is below the pointer.
The marksman often finds it difficult to keep one eye shut and at the same
I provide an
time to look steadily with the other eye at the object aimed at.
adjustable shield or shade that is so placed as to cover the object aimed at, as the
same would be observed by the left eye; hence the marksman can keep both eyes
open but he will only see the object aimed at by one eye-usually the right, but
of course the shade can be reversed in position to allow for sighting with the left
eye. I attach to. the frame C the projecting bars L by the screws 12 and within
these bars are the vertical slide bars M carrying the shade or shield N and there
is a block 13 and screw 14 by which the shade N is connected to the vertical
bars M so that this shade N can be raised or lowered to the same height as the
sight G and if necessary it can be moved with the bars M laterally, to a greater
or less distance according to the distance of the target or object aimed at so that
such shade effectually intervenes between one eye of the marksman and the object
aimed at, allowing him only to see that object through the peep hole of the sight G.
These bars L may be attached at either side of the frame C so as to be in front of
either the right or the left eye.
It is usually preferable to provide an index or scale 16 upon the base A and a
pointer upon the transverse slide I so that, in adjusting the wind-guage, the movement
may be more or less, according to the velocity of the wind.
Having now particularly described and ascertained the nature of the said invention
and in what manner the same is to be performed I declare that what I claim is :--
1 The base A having a hole for the screw 2 and a longitudinal slot for the screw 3

page_text: in combination with the slide cover B passing into the slot above the screw for closing
the slot, and the frame above the base, and the adjustable sight sliding vertically in
the frame, substantially as set forth.
2. The combination, with the base A and the frame or leaf C and vertically-
adjustable sight G within the frame, of transverse slide I and the joint 5 and 6, for
connecting the frame C to the slide and the spring 7 upon the slide acting to hold
the joint-piece 6 and frame C in any position to which it may be turned upon the
hinge, substantially as set forth.
3. The combination, with the vertical frame C the sight G and the adjustable
block F sliding in the frame and supporting the sight, of a separate removable
tubular screw passing through the block and into the sight and forming the peep-
hole of the sight such screw being changeable to vary the size of the tubular peep-
hole, substantially as set forth.
4. The combination, with the sight G frame C and base A, of the transverse
slide within ways or grooves across the base and the hinge-pieces on the transverse
slide for connecting it to said frame C and the screw K across the base A for
adjusting the slide transversely of the base A, substantially as set forth.
5. The combination with the sight and the frame for supporting the same, of
lateral bars L, extending from the sight frame, the vertical bars M supported by
said bars L and the shade or shield carried by such vertical bars M and vertically
adjustable upon such bars M substantially as set forth.
6. The vertically-adjustable peep-hole sight and the shield or shade to intervene
between one eye and the object aimed at and shut off the vision in combination with
a frame and vertical bars for carrying the sight and the shield and in which the same
can be adjusted vertically, substantially as set forth.
7. The base A having a hole and screw 2 therein and slotted longitudinally at one
end and a screw 3 therein in combination with the adjustable slide and frame above
the base and the adjustable sight sliding vertically in the frame, substantially as set
forth.
