UNITED STATES PATENT orrron.

Specification of Letters Patent.

Patented March 5, 1907.

Application filed May 10. 1906. Serial No. 316,097.

To atl/Z whom, it nca/y concern:

Be it known that I, DEAN WV. KING, Jr., a citizen of the United States, and a resident of San Francisco, in the county of San F rancisco and State of California, have invented a new and Improved Gun-Sight, of which the following is a full, clear, and exact description.

The purpose of the invention is to provide a gun-sight in which a vertically-adjustable square or rectangular diaphragm is employed having a white or illuminated rectangular or diamond figure on one face and diferent sizes or shapes of notches in its four edges, whereby to enable the marksman to use any one of the four notches with either side of the diaphragm at any desired elevation, providng for eight combinations, and giving him a rear sight to suit the eyes and to conform to the size and shape of the front sight used and also render the sight adaptable to various conditions of weather, light, or background.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth,

and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this speciiication, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a perspective view of a stepped sight mounted upon a barrel having the improvement applied. Fig. 2 is a longitudinal vertical section'through the sight and barrel shown in Fig. 1. Fig. 3 is a transverse section taken practically on the line 3 3 of Fig..

' 2. Fig. 4 is a transverse section taken practically on the line 4 4 of Fig. 2. Fig. 5 is a horizontal section taken substantially on the line 5 5 of Fig. 3, being drawn upon an enlarged scale. Fig. 6 is an enlarged detail view ofthe adjusted diaphragm. Fig. 7 is a rear elevation of a leaf-sight having the improvement applied. Fig. 8 is a front elevation of the said leaf-sight; and Fig. 9 is a vertical central section through the leaf-sight, the section being taken practically on the line 9 9 of Fig. 7.

A represents the body of the rear sight for a firearm-a rifle, for exam le-and said body is provided at its rear face with the customary concavity 10, and at the central portion of its forward face a vertical recess 11 is formed, and in the side walls of this recess slideways 12 are made, as is best shown in Figs. 4, 5, and 7. When the sight is to be employed as a leaf-sight, as is shown, for example, in Figs. 7, 8, and 9, the concavity in its rear face is generally more pronounced, as shown at 10a in the said Fig. 7.

A diaphragm B is employed in connection with the bo dy of the sight, and this diaphragm B, as is particularly shown in Fig. 6, is square or rectangular, and in the central portion of each edge a notch is produced, the said notches being consequently four in number, which are designated at 13, 14, 15, and 16. These notches are of different shapes and of different sizes to suit varying conditions. For example, the notch 13 is of U shape, the notch 14 V- shaped, the notch 15 also V-shaped, but of less dimensions than the notch 14, and the notch 16 is shown U-shaped, but of less dimensions than the notch 13. I desire it to be understood, however, that I do not confine myself to any p particular formation of notch or to any par` ticular order of their arrangement.

In one face of the diaphra m B a white or illuminated rectangular or iamond shaped panel 17 is formed flush with the face of the diaphragm in which the panel is introduced or produced, and in the arrangement of the panel 17 a corner ofthe panel is in alinement with the central portion of each of the

notches

13, 14, 15, and 16, so that in overcast or dark weather the eye is directed by said illuminated panel to the central portion of the notch through which aim is to be taken. The opposite face of the diaphragm B is black or opaque.

The diaphragm B is introduced into the slideways 12 of the body of the sight and is adjusted up and down as occasion may require, and it is reversible, any desired edge being capable of being made the upper edge. The said diaphragm B is held in its adjusted position, preferably, by means of a screw 18,

passed into the body from the front at one side of the slot or opening 11 in which the diaphragm B is located, the said screw being so placed that it will have bearing either against the outer wall of the slideways 12 or against a side edge of the diaphragm, as best shown in Fig. 5.

When the body A of the sight is to be employed as a stepped sight or is to have stepped adjustment independent of the adjustment to the A diaphragm B, the construction is as shown in Figs. 1, 2, 3, and 4, Where- IOC) IIO

in it will be observed that a spring-shank 19 is secured to the bottom central portion of the body A, and this shank extends forward along the top of the barrel C and adjacent to its forward end is provided With a dovetail tongue 20 upon its under face, adapted to enter a dovetail recess 21 in the upper face of the barrel. The free end of the shank 19, and consequently the body A of the sight, are raised and lowered through the medium oi an adjusting member D. This adjusting member consists of a base-plate 22, which slides upon the barrel and supports the rear portion of the shank 19, and vertical sections 23 are carried up from the bottom plate 22 at each side, the upper edges of the said side sections being inclined in direction of the rear of the barrel, and said edges are provided with steps 24, the steps in the side sections 23 corresponding in number and arrangement, and are adapted to engage with the lower edge of the body A of the sight at each side of its center, and the said sight A is adjusted up or down by moving the adjusting member D backward or forward. To that end the base-plate 22 of said member is provided with an upwardly-extending thumb or iinger piece 25. By this construction of the adjusting member D steps are provided for each side of the body A, permitting the steps to be higher than when a single central setof steps is employed, and the improved construction also prevents blurring in the notch and renders the sight more stable and rigid.

When the sight is to be employed as a leafsight, as is illustrated in Figs. 7 8, and 9, the body A is connected by a hinge 26 with a dovetail block 27, which is itted in the aforesaid dovetail slot or groove 21 in the barrel, and under thi-s construction of sight when the sight is not needed it can be folded down to lie flat along the barrel.

Under the construction shown in F ig. 1 it will be observed that a rapid and coarse adjustment ofthe rear sight is'obtained, while a iine adjustment may be secured by the individual adjustment ofthe notched diaphragm.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. In a gun-sight, a body having an opening therein and a square diaphragm adjustably and reversibly mounted in said opening, the said diaphragm having notches in its edges of varying sizes and shapes said notches being at the centers ofthe respective sides ofthe diaphragm.

2. In a gun-sight, a body having an opening therein and a square diaphragm adjustably and reversibly mounted in said opening,

the said diaphragm having notches in its edges of varying sizes and shapes, said notches being at the centers of the respective sides of the diaphragm and means for holding the diaphragm in adjusted position and means for bodily raising andtlowering the said sight.

3. In a gun-sight, a body having an opening therein and a diaphragm mounted to slide in said opening, the upper edge of the diaphragm being visible from the front and the rear of the body, the said diaphragm being provided with notches in its edgesor' varying shape and size, the said diaphragm being also provided with a white or illuminated panel upon one face the corners whereof center the said notches, and means Jfor holding said diaphragm in adjusted position.

4L. In gun-sights, the combination with the body of the sight, of a square sighting-dia phragm adjustably, removably and reversily supported in the said body, the said diaphragm having sight-notches in its edges of varying sizes and shapes said notches being at the centers of the respective sides of the diaphragm.l

5, In gun-sights, the combination with the body of the sight, of a sighting-diaphragm adjustably, removably and reversibly supported in the said body, the said diaphragm having sight-notches in its edges of varying sizes and shapes, the said diaphragm being also provided with a diamond-shaped white panel upon one of its faces, the corners oit' which panel center the saidnotches.

6. In a gun-sight, the combination with a body-section, a spring-shank secured to the bottom portion of said bodysection, means Jfor attaching the said shank to a barrel, and a si ghtingdiaphragm adjustably, removably and reversibly supported in the said body, the said sighting-diaphragm having notches in its edges of varying shapes and sizes, of an adjusting member comprising a plate adapted to slide beneath the free end of `the shank, side pieces extending up from the side edges of the said plate, the upper edges of which side pieces are downwardly and rearwardly inclined and stepped, which stepped surfaces engage with the body of the sight at each side of its center, and means for moving the said adjusting member.

In testimony whereof I have signed my name to this speciiication in the presence oi two subscribing witnesses.
