COMBINATION RIFLE-SIGHT.

SPECIFICATION forming part of Letters Patent No. 766,447, dated August 2, 1904-.- Application filed November 23, 1903- Serial No. 182,329. (No model.)

To all whom, it may concern:

- Be it known that I, CHARLES Krnssre, a citizen of the United States, and a resident of San Diego, in the county of San Diego and State of California, have invented certain new and useful Improvements in Combination Rifle-Sights; 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 accom panying drawings, and to the figures of reference marked thereon, which form a part of this specification.

My invention relates to gun sights, and more particularly to those used on rifles; and it consists in the improved and effective construction hereinafter set forth.

The object of my invention is to produce a gun-sight which will give a clear vision and not a blurred one, as is now given by the sights in common use. This object I accomplish by substituting hard rubber in the place of metal in the rear open sight and also by such other devices and combination of devices as will be hereinafter clearly set forth, and

particularly pointed out in the claims appended.

In order that my invention may be clearly understood and readily carried into effect, I will now proceed, aided by the accompanying drawings, fully to describe the same.

Referring to the drawings, Figure 1 is a top plan view of my improved combination riflesight. Fig. 2 is a side elevation of the same. Fig. 3 is a rear end elevation showing a globesight in a horizontal position. Fig. 4 designates a front elevation with the globe-sight raised to a vertical position and with the sight partially raised. Fig. 5 is a longitudinal section taken on a line w w of Fig. 1.

Similar figures of reference indicate corresponding parts in the several views.

1 is a metal extension-plate suitably constructed with the front in a little higher plane than the rear end. 1 is a longitudinal slot in same.

2 represents standards or guide-pins arranged on and forming component parts of the rear of the plate.

3 is a globe-sight acting on a pin-axle 3.

4 is the metal frame of the sight, provided with lugs or proj ections 4, in which lugs the axle3 is seated. Said frame is also provided with pillars 4 forming component parts of said frame and bored to fit over the standards or guide-pins 2.

5 is a hard-rubber or gutta-percha open sight dovetailed or otherwise suitably fitted into the frame 4 between the pillars 4.

6 is a milled screw located in the side of one of the pillars 4 and engaging with one of the guide-pins 2.

7 is a base-plate provided with an upward projection or guide 7, adapted to fit and act in the slot 1. Said base-plate 7 is dovetailed to the gun-barrel in the usual manner.

8 is a set-screw in the projection 7 and baseplate 7 adapted to secure the said base-plate at any desired point in the slot 1. p

The use of gutta-percha or rubber has been found by experience to entirely eliminate blurs or blotches which appear when metal is used, the latter even when-colored by smoking, bluing, or tempering being objectionable, owingto the presence of the blurs or blotches. This blur in the notch prevails when metal is used in all kinds of light or shadow, obstructing an accurate view of the front sight, not'present when rubber or guttapercha is employed, the latter being used in their natural colored state.

The mode of operating my improved gunsight is as follows: When it is' desired to use the open sight only, the globe-sight is turned down, as shown in Fig. 1. When the globesight is needed, it can be raised to the position as shown in Fig. 4, with the hole therein on a direct line with the notch in the open sight. When desired to adjust the distance between the front and rear sights of the gun, loosen the set-screw 8 and shove the plate 1 along the guide 7 until the desired distance is attained. Tightenthe set-screw 8 and get the proper elevation for range by raising the frame 4 on the guide-pins 2 and then look said frame to pins 2 by means of milled screw 6. The rear sight is made adjustable longitudinally, for the reason that some users prefer the sight as near the eye as possible, while others prefer it farther off, and as most gun-barrels have the slot already cut in them to receive the sight the adjustability of the sight is a convenience for the shooter.

Of course in practice the globe-sight may be left off entirely, if so desired.

I have entered into a detailed description of the construction and relative arrangement of parts embraced in the present and preferred embodiment of my invention in order to impart a full, clear, and exact understanding of the same. I do not desire, however, to be understood as confining myself to such specific construction and arrangement of parts, as such changes or modifications may be made in practice as fairly fall within the scope of my claims.

Having thus described my invention, what I claim as new and useful, and desire to secure by Letters Patent, is-

1. In a gun-sight of the kind described the combination of a suitable extension-plate provided with a longitudinal slot in the front end. thereof, standards or guide-pins at the rear end of said plate and forming component parts thereof, a sight-frame provided with suitable vertical pillars said pillars being centrally bored, baokwardly-projecting lugs on said frame, a globe-sight pivoted between said lugs, a hard-rubber open sight fastened securely between the vertical pillars, a milled screw fitted in one of said pillars, a base-plate adapted to be fastened to the gun-barrel, an upwardly-projecting guide on said base-plate adapted to fit into the slot in the extensionplate, and a set-screw acting in said guide all as set forth.

2. In a rifle-sight the combination with a suitable base-plate provided with a suitable guide and set-screw, of an extension-plate, a slot in said extension-plate adapted to receive the said guide, standards or guide-pins at the rear of said extension-plate forming component parts thereof, a suitable sight-frame, slotted pillars on said frame adapted to fit over and act on the guide-pins, a hard-rubber or gutta-percha open sight fitted into said frame between the pillars thereof, and a milled screw seated in one of the pillars and engaging with one of the guide-pins, said milled screw adapted to clamp the frame and its parts on the guide-pins, all as set forth and described.
