FRANK \V. FREUND, OF CHEYENNE, WYOMING TERRITORY.

SIGHT FOR FIRE-ARMS.

SPECIFICATION forming part of Letters Patent No. 268,090, dated November 28, 1882. Application filed August 19, 1881. (No model.)

To all whom it may concern:

Be it known that I, FRANK W. FREUND, of Cheyenne, in the county of Laramie and Territory of Wyoming, have invented certain new and useful Improvements in Rear Sights for Fire-Arms, as hereinafter described and claimed.

This invention is an improvement on the sight shown in my patent of June 29,1880, No. 229,245; and it consists in applying to said sight a movable or sliding plate by which the opening below the sight-notch can be opened, partially opened, or entirely closed, as may be desired.

In the accompanying drawings, which illustrate my invention, and in which the figures are all rear views, Figure 1 shows the opening in the sight entirely closed. Fig. 2 shows it partially open. Fig. 3 shows the movable plate or slide entirely removed from the sight. Fig. 4 shows the plate in position to have the opening entirely open'. Fig. 4 shows an elevation in reverse view of the movable plate. Figs. 5 and 6 show sights with a vertical slideway, with slides to move up and down, the first showing the opening closed and the second showing it open.

In the several figures, arepresents the body or leaf of the ordinary rear sight, which may be made in any preferred shape. 22 represents the sight-notch, and 0 represents the opening below the sight-notch, all as described in my patent above referred to.

01 represents an undercut or dovetailed groove or slideway in the body of the sight, which receives a correspondingly-shaped part, 0, of the plate e.

In Figs. 1, 2, 3, 4, I have shown the plate arranged to move horizontally, while in Figs. 5 and 6 it is shown arranged to move vertically.

It is evident that the details of construction may be varied-as, for instance, the groove or slideway may be formed in the sliding piece and the correspondingly-projecting tongue be formed on the body of the sight; or, instead of the slideway, the plate 6 may be pivoted to the sight, so as to be moved over or away from the opening. These I regard as equivalents, and do not therefore wish to be limited to the precise construction shown in the drawings.

So far as I am 'now aware, I am the first to apply a sliding or movable piece to a sight provided with an opening below the sightnotch, and therefore claim as my invention-- A rear sight for fire-arms, consisting of a sight-plate providedwith a sight-notch and with an opening below said notch, and a sliding plate of a size to cover said opening, and arranged, substantially as shown, to be moved over or partially over or entirely away from said opening, as and for the purpose described.

FRANK W. FREUND.
