GUN-SIGHT.

SPECIFICATION forming part of Letters Patent No. 450,469, dated April 14:, 1891.

Application filed June 21, 1 8 90.

To all whom it may concern:

Be it known that I, WEBSTER L. MARBLE, a citizen of the United States, residing at Gladstone, in the county of Delta and State of Michigan, have invented certain new and useful Improvements in Rear Sights; and I do de-' ferent sizes to give a clear view substantially all around the peep-hole in use; to be able, however, to cut off all the light around the peep-hole when desired; to render the sight vertically adjustable to any point within range of its movement at an instants notice, and noiselessly; to regulate the angle of the standard to the base when the sight is turned up into position, so as to adapt the sight to stocks of different slants; to adapt the sight for use as a wind-gage; to render it applicable to any stock, and to provide a movable shield'that shall act as a shade for the eye and as a protection against blows when the piece recoils.

The accompanying drawings illustrate my improved sight, Figure 1 showing a front view; Fig. 2, a side elevation, the base being in section Fig. 3, a detail view of the shutter; Fig. 4, a plan view, partly in section. Fig. 5 is a vertical section through the disk on an enlarged scale. Figs. 6 and 7 are details.

The base A is an oblong casting of the usual shape, but it is slotted from one end to the other. This gives an opportunity to putin the holding-screws a wherever desired, so that the sight can be applied to stocks in which the screw-holes are already made, even though they may be at different points on one stock from those on another. The base is rabbeted or beveled on its inner edges to afford ashoulder for the heads of the screws to bear upon. The base has the ears a, between which is hinged the foot of the standard B. The width Serial No. 356,258. (No model.)

of this foot is slightly greater than the space between the cars, so that the foot is clamped by them and all wear is taken up by the resilience in the metal of the base. A set-screw b is inserted into the foot at an angle to the length of the standard, so that its head will come to abearingupon the stock between the sides of the base A when the standard is turned up into position. In this way the standard can be adjusted to stand vertical, irrespective of the slant or inclination of the stock. The standard is slotted from its bottom to near its top, a thin web of metal I) being left to prevent the parts from separating, as they would do if the slot ran clear to the top. Above the web there is preferably a notch b On the standard is mounted the carrier 0. This consists, preferably, of a block of metal grooved on' its edges to receive the standard, and slotted from its lower end nearly to its top to allow the web 11 to pass up through it when it is slipped down over the standard. The grooves in its edges are made a tight fit on the standard,

so that the carrier will move stiffly thereon,

and will remain at any point to which it may be moved. In order,- however, to hold it positively, a screw 0 is tapped into a hole in the lower part of the carrier, being inserted after the carrier has been slipped down into place. The screw passes freely through the slot in the standard, and by tightening it the lower ends of the carrier are clamped firmly upon the standard. WVhen the carrier is raised, the screw strikes the web 1) and prevents it from coming off the standard. One edge of the standard may he graduated to serve as an index by which to set the sight at the proper elevation. Through the upper end of the carrier, above the slot, is passed a screw or bolt 0, which rests in the notch b when the carrier is down, and which projects suffioiently to permit two disks D D to be rotatably mounted thereon, one behind the other. The disk D contains the peep-holes 1 2 3 4 of varying diameter, as shown, disposed at equidistant spaces. Around each peep-hole is a small circular disk of metal, adhering to the central hub of the disk on its inner side, and to the circumferential rim of the disk on its outer side, the rest of the disk being cutaway, as shown, to give an unobstructed view on nearly all sides of each small disk. I prefer to counterbore the small disks and set into them around the peep-holes a piece of zylonite d, or other similar material, that shall present a dead black or other colored but non-reflecting surface adjacent to the peep-hole. On the rim of the disk in the radial line of each peep-hole is made a mark (1', which is adapted to register with a mark on a scale C, fastened to the carrier 0, and consisting of a T-shaped piece of metal, graduated, as shown, and having its upper edge curved to conform to the edge of the disk. It is secured by a screw passing through a short slot, so that it can be adjusted close to the disk to take up wear and to act as a brake when desired. By turning the disk to bring the mark d into coincidence with one of the graduations at one side of the middle of the scale the sight can be adjusted to compensate for the wind, and thus the scale serves as a wind-gage.

The disk D is a shutter, being solid, with the exception of the hole (Z and the aperture d diametrically opposite. The hole (Z is preferably elliptical and is large enough to permit a practically unobstructed view on both sides of the peep-sight when turned uppermost, as shown in Fig.1.

When it is desired to cut off all the light around the peep-sight, the disk D is turned the other side up, bringing the aperture (1 into line with the peep-hole.

To retain the disks in their properpositions, a double springcatch E is fastened rigidly to the carrier in front of the disks and extending transversely to either edge of the same. On each side of the spring is a tooth 6, one of which is shorter, and is adapted to engage with one of two notches or holes in the disk D to hold it in its two several positions. The other tooth is longer and projects through the disk D into notches in the disk D, which are made at such points that the disk will be held with one of the marks d registering with the center mark on the scale C. The ends of the spring are preferably milled, so that it can be readilygrasped and forced back to disengage the teeth when the disks, or either of them, are to be turned. It will be perceived that each disk can be rotated independently of the other. The scale C bears against the edges of both disks. I provide also a shield F, consisting of a partial hoop of sheet metal, preferably spring-steel, adapted to slip over the disks in the" manner shown in Figs. 1 and 5. The ends of the hoop rest against the ends of the scale C. The shield can be moved back and for h on the sight to project more or less fromthe face of the disk D and shade it more or less from the light. The projecting edge of the hoop is preferably inclosed in a rim of some soft material, preferably rubber f, to serve as a protective cushion and prevent the face of the hunter from being injured by the recoil of the piece when the sight is held close to the eye. This effectis still further provided for by the fact that the hood slides stiffly on the periphery of the disks, and will therefore yield to sudden pressure, such as results from the recoil of the gun. Moreover, this shield, with its rubber rim, acts to prevent the stock of the gun from being marred by the sight when it is turned down upon it.

Having thus described my invention. what I claim, and desire to secure by Letters Pat out, is-

1. A rear sight having its base A slotted from near one end to near the other, so as to permit it to be attached to stocks whose screws are set at ifferent distances apart, substantially as described.
