GUN-SIGHT.
SPECIFICATION forming part of Letter'sPatent No, 280,484, dated July 3, 1883. Application filed August 18, 1882. (No model.)
To all whom it may concern.-
Be it known that I, JOHN C. KELTON, of the city and county of San Francisco, State of California, have invented an Improved Rifle- Sight; and I hereby declare the following to be a full, clear, and exact description thereof.
My invention relates to certain improvements in the rear sight of rifles, and it is more particularly adapted for use upon the United States Springfield rifle and carbine as at present constructed, although it may also be used upon other rifles.
The object of my invention is to enable the sight to be more quickly and correctly adjusted when the distance of the firer from the object fired at changes quickly and often, and also to provide a better lateral adjustment to counteract the deflection caused by the wind when aiming directly upon the object.
It consists of a base which is fixed to the barrel of the gun, a hinged leaf having side bars which fall outside the base, and a slide which has a movement only in the direction of the length of the bars. This slide carries the buckhorn, or sight proper. which is given a lateral movement upon it, limited by a slot in the slide, and a retaining-screw. The base has curved graduated and notched sectors projecting upward from its sides, with which the sight may be engaged, and held firmly at any desired elevation within their limit. The sight itself is in form the segment of a cylinder, with the notch extending around the curve centrally, so that its depth will be the same at all elevations. The leaf is elevated by serrated cams which engage corresponding notches beneath the leaf, and are operated by a milledheaded pin upon which they are mounted.
Referring to the accompanying drawings for a more complete explanation of myinvention, Figure l is an enlarged perspective view of my device with. leaf partly elevated. Fig. 2 is a side elevation. Fig. 3 is a rear elevation with the leaf raised to a full vertical position. Fig. 4. is a plan. Fig. 5 is an enlarged perspective view of the sliding bar. Fig. 6 is a section of the sight proper. Fig. 7 is a section of the sliding bar D and the screwc.
A is the base-plate of the sight, which is fitted and secured to the barrel of the gun in the usual or in any suitable manner.
B B are the side bars of the sight-leaf, which are united near the hinge-pin by a transverse plate, B, which forms a part of the leaf, but are left entirely unconnected at the outer or moving end, as a transverse bar at this point would interfere with the line of sight through the rear notch. Upon the bars B the slide 1) Dyis fitted, the lower part, D, being notched or channeled, so that it fits the bars exactly, and only slides longitudinally upon them, instead of having a longitudinal and lateral adjustment, as in the ordinary sight. The top plate, D, of the slide has a slot, a. formed in it, which is transverse to the barrel of the gun,
and the buck-horns b and sight proper, b, are I w sight-plate travels against a raised shoulder, d, upon the top plate of the slide D, so that there will be no unsteady or turning motion as it is moved from side to side, and to still further steady it the front edge may extend down over the edge of the slide. The central part,- b, of the sight, in which the notch or sight-mark is formed, is made in the form of a segment equal to about one-fourth of a cylinder, and the sight mark or notch 6 extends around this curved portion for the purpose of keeping it of equal depth, or equally in viewas the leaf is raised about its hinge, so as to stand at different points between a horizontal and a perpendicular position.
In order to adjust the sight quickly for varying distances as upon a skirmish-line-two cams, f, are fixed to a pin, 9, which passes through a base-plate just in front of the hingepin, and is provided with a milled head, h, by which to turn it. The cams f are fixed to the pin just beneath the side bars, B, of the hinged leaf, and when turned they will press upon the lower sides of these bars and raise them and the sight to any desired elevation. \Vhere the elevation is constantly changing, the cams are designed to hold the side bars and sight'at any point where they may be set,
75 effect of side wind. The rear part of the without other assistance, and they will be prevented from slipping by serrating the ends of the cams and the corresponding faces of the side bars.
When it is necessary to fix the sight for some known or fixed distance, it is done by means of the curved sectors G, which project upward from the sides of the base A at a point about midway from the rear to the front end. The front or curved edges of these sectors are graduated and notched, as shown, so that the rear edge of the sight-plate may be held in any one of the notches, while by the curve of thesightnotch it is kept practically of the same appearance, whatever may be the angle of elevation. By this manner of elevating the sight it is also kept at the same distance from the eye, which is thus not strained. Provision is made for fixing the sight for battle-range-that is, the
elevation which gives the projectile the longest dangerous space-by the support H, fixed to the front of the base-plate, upon which the sight maybe supported and kept during battle.
i'he base A, and the slide D, fitting the bars, so
as to move longitudinally thereon, and having the lateral slot a, in combination with the cylindrically-shaped sight b, secured to the slide by a screw passing through the slot to admit of lateral adjustment, and having the sight mark or groove e formedup on its curved surface, substantially as described.
8. The side bars, B, of asight-leaf,l1inged to the base A, and having the laterally-adj ustable eylindrieally-curved sight, I), fitted to them, as shown, in combination with the curved graduated and notched or serrated sectors G, curving upward and backward from the base, substantially as herein described.
4. The side bars, B, of a sight-leaf, hinged to the base A, the slide D, fitted to the bars for vertical adjustment, and the laterally-adjustable cylindrically-shaped sight b, in combination with the cams f and milled head h, and the graduated sector G, by which the elevation of the sight is retained, substantially as herein described.
5. The side bars, B, of a sight-leaf, hinged to the base A, and carrying the vertically-adjustable slide D, and the laterally-adjustable sight I), in combination with the sector G for variable elevations, and the projections H for a fixed or battle-range elevation, substantially as herein described.
In witness whereof I hereunto set my hand.
J. C. KELTON.
