GUN-SIGHT.

SPECIFICATION forming part of Letters Patent No. 353,786, dated December '7, 1886.

Application inea An-i123, ieee.

.T0 all whom it may concern:

Be it known that LFRANK E. HALLADAY@ citizen of the United States,residing at Plover, in the county of Portage and State of Wisconsin, have invented certain new and useful Improvements in Gun-Sights', of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in Which- Figure l represents a perspective view of a gun-sight embodying my improvements. Fig. 2 is a longitudinal sectional view of the same.

My invention relates to sights for firearms; and `it comprises a spring-plate, a horizontal screw, and wedge-shaped block for adjusting the sight, as I shall hereinafter fully describe and claim.

To enable others skilled in the art to make and use my invention, I will now describe lits construction and the mannerin which it is carried out.

In the said drawings,Arepresents a portion of a gun-barrel on which the sight is secured, provided with a dovetailed slot, a, in which is iitted to be adjusted laterally the dovetailed head b of the leaf B. This leaf is simply a spring plate rmly held to its engagement with the barrel A by reason of the dovet-ailed connection before described, and having at its front the projection b, provided with t-he usual sight-notch, b, as shown in Fig. l.

The forward end of the plate B is cut away to form the slot c, within which slides and is guided an inclined or wedge-shaped block, D, having lugs d d', resting upon the upper surface of the barrel. The lug d is provided with a threaded perforation, through which passes one endiof the horizontal screw E, the opposite end of said screw being secured in a ro-v tating nut. e, j ournaled within a slot, f,formed in the head b of the plate B, as shown.

From this description it is manifest the movement of the screw and rotating nut in either direction will cause the wedge shaped block to advance or recede. As said block passes beneath the projecting portion b of theplate or ,the shooting.

Serial No. 199,882. (No model.)

which, when once adjusted, is not affected by light winds, head or rear winds, nor by varying charges of powder, which require a change of elevation or depression, and which in other sights often so modify the previous adjustment as to seriously affect the result of I am also enabled to obtain elevation for any distance where a spring-sight is used. The sight may also be instantly' changed, does not require watching, is readil y operated, and is adapted for all sizes and calibers of guns,and for light or heavy charges of powder.

Having thus described my invention,` what I claim as new, and desire to secure by Let-ters l. An improved sight for iire-arms, comprising a spring-plate, B, a block, D, sliding upon the barrel and having an inclined face engaging said plate,and a screw engaging the block, whereby the sight is adjusted.

2. The combination, with the springplate B, one end of which is secured in a slot formed in the barrel, of an inclined or wedge-shaped bloclcsliding upon said barrel, and adjusting the spring-plate, and a screw and nut for moving the block, substantially as hereindescribed.

3. rlhe combination, with the barrel of a gun provided with a dovetailed slot, of the plate B, having a head fitting within the slot,a slotted forward portion,and a projection, b, asliding block having an inclined upper face engaging the plate B,a horizontal screw mounted in said plate and engaging a threaded aperture in the sliding block, and an operating-nut secured to the screw, substantially as herein described.
