GUN-SIGHT.

SPECIFICATION forming part of Letters Patent No. 410,422, dated September 3, 1889. I Application filed Pebruaryl, 1889. Serial 110,300,034- (No model.)

To aZZ whom it may concern.-

Be it known that LBENJAMIN LONG, a citizen of the United States, and a resident of Boulder, in the county of Boulder and State of Colorado, have invented certain new and useful Improvements in Gun-Sights; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to gun-sights.

The object is to produce a combined gunsight and distanceindicator which shall be of such construction that the person using it may with readiness and certainty determine the distance of an object from the point at which he stands, and also the angle at which to elevate the barrel of the gun; furthermore, to produce a gun-sight which maybe secured to any gun or rifle at but a slight expense, and which will be conducive to more perfect long-distance shooting than the ordinary sights now in use, and, final1y,-to produce a gun-sight which,'while being comparatively simple of construction, will be found of the highest efficiency and utility in use.

WVith these objects in view, the invention resides in a gun-sight consisting, essentially, of a sight-carrier hinged in a suitable manner to the barrel of the gun, the said sight-carrier being provided with a lever, by means of which it may be elevated to any desired distance; furthermore, in the combination, with the said sight-carrier, of a movable sightpieoe and means for op erating the sam e,whereby when the sight-carrier is raised the sightpiece will also be raised, so as to enable the marksman to determine any distance that may be desired; furthermore, in the combination, with the sight-carrier having a lever secured thereto to elevate the same, a'sightpiece moving within the sight-carrier and designed to enable the marksman to determine the distance of an object, of a spring for operating both the sight-carrier and the sightpiece to cause the former to resume its normal position after being used and the latter to be raised when the sight-piece is raised; and, finally, the invention consists in the various novel details of construction whereby its objects are attained.

mounted thereon.

In the accompanying drawings, forming part of this specification, and in which like letters of reference indicate corresponding parts, I have illustrated one form of device embodying the essential features of my invention, although the same may be carried into effect in other ways without in the least departing from the spirit thereof.

In these drawings, Figure 1 is a side view of a portion of a gun-barrel with the sight Fig. 2 is a top plan view of the same. Fig. 3 is an end view. Fig. 4 is a longitudinal sectional view. Fig. 5 is a bottom plan view of the sight-carrier. Fig. 6 is a detail view of a tilting slide carrying the sight, and Fig. 7 is a detail view of the spring for actuating both the tilting slide and sightcarrier.

Referring to the drawings, A designates a gun or rifle barrel upon which is mounted my improved sight. This sight may be secured on the barrel at any point convenient to the eye.

B designates the sight-carrier,on one side of which is formed a lever 1, which fits down against the side of the gun-barrel, and is provided on its outer end with a button 2, by means of which it may be moved. The forward end is provided with an opening designed to be engaged by a screw 3, which passes through two ears 4, formed on a crosspiece 5, which is dovetailed on its lower side and fits in a dovetailed recess 6, formed in the barrel. The rear end of the sight-carrier fits in a similar cross-piece 7, secured in the same manner to the gun-barrel, so that the said carrier is always held in its proper position, and is prevented from being knocked out of adjustment by side blows or by the piece falling.

' At the rear end of the sight-carrier, or that portion next the breech of the gun, is formed an opening 8, and the under portion of the sight-carrier is cut out to form a recess 9, in which fits a tilting slide 10. This slide is held in position in the sight-carrier by means of a screw 3, and extends up level with the top of the sight-carrier and carries on its outer end a lip 12, provided with a sight-notch 13. Immediately in front of the sight-notch the metal is cut away to form a groove 14, so that the sight on the muzzle of the barrel will not be obstructed from view. 3

Upon the screw 3 is mounted a spring 15, the ends of which are formed into coils 16, the ends 17 of which extend out, as shown. The upper end 18 is designed to rest upon the top of the tilting slide 10, and the ends 17 to extend through the recess 19 in the sightcarrier and rest upon the cross-piece 5. Thus .when the lever is pressed down the spring will cause the tilting slide to be forced out and thus tilt up the end carrying the sightnotch; but as soon as the lever is released the ends 17 of the spring will force the sight-carrier down to its normal position. The ends of these wires serve to limit the height to which the rear end of the sight-carrier may be moved, for when it has reached its highest limit the wires come in contact with the upper edge of the recess 19, and thus prevent its being raised any higher, and by reason of the curved shape of the lower end of the sight-piece the rear end of the sight-carrier will be raised more rapidly at first, and less rapidly as the said end is raised higher.

On each side of the rear end of the sightcarrier is mounted a slide 20, provided with a slot 21, through which extends a screw 22. In each of these slides are formed a number of small openings 23, carrying horizontal wires 24, the ends of which are coiled around the screws 22, as shown. These wires are designed to be used to determine the distance of an object from a certain point, as will be described farther on.

Upon the gun-barrel may be marked a graduated scale 25, each line representing one hundred yards, and on the lever 1 is formed an indicator 26, which enables the marksman to determine the elevation of the piece. Thus when the indicator coincides with the marks on the scale the rear end of the sight-carrier is elevated to the proper height for shooting at the distance indicated by the figure to which the indicator points.

In using this device the perpendicular distance between the bottom of the notch 13 and the first horizontal wire above it will measure a perpendicular height of one foot at a distance of one hundred yards. By fastening the device nearer to the eye, or by raising the adjustable wires and increasing the space between them, a perpendicular height of two or three feet or more may be measured by the perpendicular distancebetween the notch and the wire. This sight may be so adjusted that the first space will measure one or more feet at one hundred yards, two or more feet at two hundred yards, and so 011. Thus when the rear end of the sight-carrier is raised to such a height that the first horizontal wire disappears, then the marksman knows that the object aimed at is two hundred yards or more distant, or when raised to the second wire the object is three hundred yards or more, and when raised to the under side of the inward-projecting lugs 27 on the top of the sight-carrier, which serves as a third horizontal wire, he then knows that the object is fourhundred yards or more distant. In practical shooting, the marksman, 011 looking at the object through. the sight-carrier, can tell at a glance which one of the spaces between the wires most nearly covers the top and bottom of the object to be aimed atsay the feet and head of a man or the feet and back of a deer. The marksman then raises the rear end of the sight-carrier until the notchsight comes to that space, when by consulting the graduated scale he may readily determine the distance of the animal.

It will thus be seen that although this sight is comparatively simple of construction it will admit of more accurate shooting than sights heretofore constructed, for the reason that it acts not only as a sight but as a measuring device.

Having thus fully described my invention, what I claim as 116\ and desire to secure by Letters Patent, is-

1. In a un-sight, the combination of the sight-carrier, a sight-piece pivoted therein and provided with a forwardly-curved reduced portion, and a spring exerting a downward pressure on the sight-piece, and having the rear portion thereof seated in the angle formed between the forward reduced portion and the rear enlarged portion of the sight-piece,whereby when the sight-carrier is raised the sightpiece will be forced out and raised simultaneousl y therewith, substantially as described.

2. In a gun-sight of the described class, the combination, with the hinged sight -carrier provided with a rear opening and having a suitable operating-lever, of the movable or tilting slide disposed beneath the sight-rearrier in the recess thereof and having a sightnotch on its outer end, and the vertically-ad justable horizontal wires passing transversely through the opening in the sight-carrier, sub stantially as set forth.

3. The combination of a gun-barrel having a graduated scale on the side thereof, a sightcariier lever pivoted on the said barrel, a sight-piece pivoted within the carrier and provided with a forwardly-curved reduced portion, a spring for exerting a downward pressure on the sight-piece, and having the rear portion thereof seated in the angle formed between the forward reduced and rear enlarged portions of the sight-piece, whereby when the carrier is raised the sight-piece will be forced out and raised simultaneously therewith, and a lever on the carrier having an indicator moving over the said scale, substantially as described.
