SIGHT FOR FIRE-ARMS.

SPECIFICATION forming part of Letters Patent No. 274,269, dated March 20, 1883.

' Application filed December 2,1882. (ModeL) To "all whom it may concern Be it known that I, RICHARD CANNON, of Washington, in the county of Washington and State of Pennsylvania, have invented a new and Improved Reflector for Gun-Sights, of which the following is a full, clear, and exact description.

The object of my invention is to provide a. new and improved reflector for reflecting light on the sight of gun in shooting-galleries which are lighted by gas or lamps.

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

Figure 1 is a perspective view of my improved reflector for gun-sights, showing. the same held on a gun-barrel. Fig. 2 isa side view of the same, showing the barrel in section on lineman, Fig. 1. Fig. 3 is a perspective view of the frame for holding the reflector on the barrel.

A small concave mirror or reflector, A, made of glass or metal, is provided on its back with the transverse parallel spring clamp-strip B, projecting slightly from the back of the reflecto'r,within which clamp-strip a wire or thin rod, 0, is vadapted to be held. The wire 0 is provided with a double bend or knee, as shown, and the lower end of the wire is held loosely in two eyes or loops, D, attached to a metal strip, E, fastened to a wire spring-frame, F, fitting on a gun-barrel, G. The lower end of the strip E is bent outward, and on. the saidlower bent end of the strip E the lower end of the wire 0 rests. The reflector Acan be turned on the wire 0, and the wire can be turned in the rings, eyes, or loops D. The wire frame F is placed on a gun-barrel in the manner shown, and the reflector Ais so adjusted that it throws the rays of light upon the rear gun-sight, H. A like mirror can be held on the barrel at the front end to throw the rays of light on thefront sight of the barrel.

In shootinggalleries which are lighted by means of gas, lamps, or any other artificial light, the rear sight of a gun cannot be seen distinctly, and this is very disagreeable and troublesome for the marksman and causes inaccurate firing. If my improved reflector is used, the above difficulties will be removed.

Having thus described myinvention, what I claim as new, and desire to secure by Letters Patent, isv 1. The combination, with the wire 0, having a double bend or knee at its lower end, of the metallic strip E, having loops D and arranged on a supporting-frame, F, whereby the wire 0 may be supported and turned, as and for the purpose specified.

2. In a reflector for gun-sights, the combination, with the reflector A, of the bent wire 0, in which the reflector is held, and of the wire frame F, fitting on the gun-barrel and holding the wire 0, substantially as herein shown and described, and for the purpose set forth.

3. In a reflector for gun-sights, the combination, with the reflector A, of the wire 0, the

' frame F, the strip E, having its lower end bent,

and the loops or eyes D on the strip E, substantially as herein shown and described, and for the purpose set forth. 7 l
