RIFLE-SIGHT.

Specification of Letters Patent.

Patented Apr. 2'7, 1920.

To all whom it may concern.-

Be it known that I, Gnonen S. LEWIS, a citizen of the United States, residing at Springfield, in the State of Massachusetts, have invented certain new and useful Improvements in Rifle-Sights, of which the following is a specification, reference being had to the accompanying drawings, forming a part hereof.

Under widely different conditions of use of some classes of firearms it is sometimes necessary to change the elevation considerably. The purpose of this invention is to provide an improved sight which shall be readily capable of adjustment through a wide range in orderto meet such conditions. The invention will be more fully explained hereinafter with reference to the accompanying drawing, in which it is illustrated and in which Figure 1 is a View in elevation of the improved sight.

Fig. 2 is a view thereof in section on the plane indicated by the broken line 2-2 of Fig. 1, looking in the direction of the arrows.

The supporting block a is adapted to be secured in the usual manner to the rifle and has pivoted thereon, between its ears a, by a pivot pin 5, also in the usual manner, the hinged leaf d, a spring 0 being secured to the block and adapted to engage yieldingly a notch in the hub d of the leaf (Z for the purpose of holding the leaf in working position. The leaf is slotted longitudinally, as at d, to form a guide on which may slide the sight or apertured member e. In the lower end of the slot d of the leaf (Z is fixed a hollow screw f and to the sliding sight e is secured a screw 9, the bore of the screw and the screw 9 being so related that the screw 9 may telescope within the hollow screw f. A sleeve nut h is threaded at its lower end to engage the hollow screw f and is threaded at its upper end, as at h, to engage the screw g, the screws f and 9 being left and right threaded respectively. The sleeve nut h is milled or knurled externally for convenience in operation. The movable or apertured sight e may comprise a plate 6 to which the screw 9 is secured and having an opening 6 a windage block 6 carried by a threaded spindle e mounted in guides e on the plate 6' and provided with nuts 6, and a cupped disk e provided with a hollow threaded stem e which engages the windage block 6 By slightly unscrewing the apertured disk 6 the sight is released for movement either vertically or for windage, and by screwing it up the sight is clamped in position on the leaf (1.

When the sight is raised to or nearly raised to its greatest elevation the screws f and g occupy the relation shown in Fig. 2, and when the sight is lowered to its lowest point the screw 9 is telescoped within the hollow screw f. By this arrangement a great range of adjustment of the sight is possible without complicated or expensive structure.

I claim as my invention:

1. In a rifle sight, the combination of a supporting member, a movable, apertured member mounted slidably upon the supporting member, a hollow screw secured to one of said members, a screw adapted to enter the hollow screw and secured to the other member, said screws being reversely threaded, and a sleeve nut engaging both of said screws.

2. In a rifle sight, the combination of a hinged leaf, a movable, apertured member mounted slidably upon the leaf, a hollow screw secured to one of said parts, (that is, the leaf and the apertured member) a screw adapted to enter the hollow screw and secured to the other of said parts, said screws being reversely threaded, and a sleeve nut engaging both of said screws.

This specification signed this 14th day of May, A. D. 1919.

GEORGE S. LEWIS.
