REAR SIGHT FOR GUNS.
To all whom it may concern:
Be it known that I, LEIGH WARNER Mo- GREW, a citizen of the United States, residing at Fraser, in the county of Grand and State of Colorado, have invented certain new and useful Improvements in Rear Sights for Guns; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the gures of reference marked thereon, which form a part of this specification.
My invention relates to improvements in rear sights for guns. The term rear sight in this connection is used to designate the sight located at the trigger extremity of the gun barrel. Sights of this character are adjustable in relation to the front sight, or that located near the muzzle of the gun.
My improved sight is extensible, and consists of two members movable the one u on the other, the said members being secure in place by a fastening device which is applied to the sight holder proper. These two members of the sight are slotted, and so arranged that the slots of the two parts register, forming a narrow, vertical opening through which the front sight is observed. Each of the sight members is further provided with horizontally disposed lines arranged on op osite sides of the slots of each member. Theilower sight member is vertically adjustable within an opening formed in the base of the sight, in order to obtain a point blank range adjustment in guns of different constructions. The point blank condition consists in arranging the lower sight member in such a manner that the top of the front sight is in line with the bottom of the slot or in line with the lowermost horizontal mark on the sight. If the breech of the gun or the rear extremity of its barrel where the sight is located, is of considerable thickness, causing the barrel of the gun to taper considerably from the breech toward the forward end ofthe barrel, it is necessary to adjust the lower sight member considerably in order that the front sight may lie in the same plane with the lowermost line of the rear sight and in order to do this, the lowermost sight member is moved downwardly the desired distance, before securing the sight members in Cplace. After my improved sight is adjuste for what I will term a point blank range or the distance Specification of Letters Patent.
Application led August 3, 1908.

Serial No. 446,664.
that the rojectile will travel without any material rop or fall due to gravity, the osition of the gun may be readily changev for long distances, so that the front sight shall lie in the same plane with one of the horizontal lines of the sight above the bottom of the slot. The more elevated the line which is brought into point blank relation with the front sight of the gun, the longer the range or distance of the target o1` game.
I-Iaving briefly outlined my im roved construction, I will proceed to descri e the same in detail, reference being made to the accompanying drawing in which is illustrated an embodiment thereof.
In this drawing, Figure 1 is a side elevation of a gun equipped with my improved rear sight. Fig. 2 is a rear view of the same shown in detail and on a larger scale. Fig. 8 is a top plan view of the same, or a view looking in the direction of arrow 3, Fig.2. Fig. 4 is a detail side elevation of the sight, or a view looking in the direction of arrow 5, Fig. 3. Fig. 5 is a section taken on the line 5-5, Fig. 3. Fig. 6 is a horizontal section on the line 6-6, Fig. 4. Fig. 7 is a front4 view of the same, or a view looking in the direction of arrow 7, Fig. 6. Fig. 8 is a side elevation with the fastening device removed.
The same reference characters indicate the same parts in all the views.
Let the numeral 5 designate the base of the sight, which is provided on its lower surface with a transversely arranged dove-tailed tongue 6, adapted to enter a counter part groove formed in the breech or rear extremity of the barrel.
Projecting upwardly from the upper surface of the base 5, are two separated arms 9 provided with vertical grooves adapted to receive overlapping sight members 14 and 15. The base of the sight is provided with a groove 13 adapted to receive the lower edge of the sight member 14. The sight members 14 and 15 overlap each other in such a manner that their slots are made to register. The opposite edges of both of these sight members are inserted in the grooves formed in the upwardly projecting arms 9, and properly adjusted to bring the bottom of the slot into point blank relation with the front sight of the gun barrel. A U-shaped clamping device 16 is then passed downwardly over the arms, a groove in the clamping device engaging tongues 17 formed on the outer edges of the said arms. When this U-shaped device has been moved downwardly to its limit of movement, the sight members will be secured in their adjusted relation, and the sight is ready for any range. The user of the gun, if pointing at an object within the initial point blank range, will bring the bottom of the slot, the front sight and the object aimed at, in a common plane. lf the object is beyond the original point blank range, the user cl the gun will change its position to bring one ol' the horizontal lines above the bottom of the slot, into point blank relation with the iront sight and the object aimed at and so on, the farther away the object, the higher the horizontal line used in making a point blank adjustment of the gun when aiming at an object.
The upper sight member 15 materially in creases the range capacity of the sight when the lower sight member is moved downwardly into the recess 13, as shown in the drawing. Nere it not for the vertical adjustment of the sight member 111, there would be no necessity for the sight member 15, However, if the sight member la alone were used, and were of sui'licient length to enter the recess in the top of the U-shaped fastener 16, its downward movement would diminish the range capacity to the extent oi' such movement. However, by employing the upper sight member 15, the range capacity oi' the sight will remain the same regardless of the downward movement of the member 14.
Having thus described my invention, what I claim is:
1. A rear gun sight, comprising a holder and two overlapping sight members, one extending above the other, the two members being in contact and having centrally located vertically alined slots, the lower member being ,warmly-adjustable. for point blank range on guns of diiierent breech constructions.
2. A rear sight for guns, comprising a holder, two sight members carried by the holder, the said members being adjustable with relation to eachother, and a fastening device app ier to the Vholder for locking the two sight members in the desired position of adjustment, the sight members having registering vertical slots and horizontal lines adjacent to the slots, substantially as described.
3. A rear gun sight, comprising a holder consisting or a base, having upwardly pro jecting separated arms, the said arn s being provided with interior, vertical grooves, each arm consisting of two members, two overlapping sight members inserted in the grooves orl the arms, and a clamping device applied to the arms for holding the sight members in their adjusted position, substantially as described.
4. A rear gun sight, including a holder, upper and lower overlapping members having centrally located vertically alined slots, the said members having horizontally arranged sight lines adjacent the slots, the lower member' being vertically adjustable, for the purpose set forth.
5. A rear gun sight, including a holder, upper and lower overlapping members have ing centrally located vertically alined slots, the lowerI member being vertically adjustable for point blank range on di'lt'erent guns, and having horizontal sight lines adjacent the slot.
6. A rear gun sight, comprising a holder consisting of a base having upwardly projecting separated arms, the said arms being provided with interior vertical grooves, each arm consisting of two members, a sight member inserted in the grooves of the arms and vertically adjustable, and a clamping device applied to the arms ier holding the sight member in the adjusted position, substantially as described.
In testimony whereof l ailix my signature in presence of two witnesses.
