SIGHT FOR FIREARMS;

Specification of Letters Patent.

Patented Dec. 10, 1907.

Application filed January 16. 1907- Serial No. 352.627.

To all whom it may concern:

Be it known that we, JAMEs WINDRIDGE and GEORGE S. WILCOX, citizens of the United States, and residents of Middlefield, in the county of Middlesex and State of Connecticut, have invented certain new and useful Improvements in Sights for Firearms, of which the following is a full, clear, and exact specification.

Our invention relates to a sight for firearms, and it has for its object to provide a leaf sight which shall embody a sight notch of variable form, or a series of sight notches of different forms which may individually be brought into sighting position by ready adjustment of parts.

The invention consists in the novel combination with the leaf of a pair of adjustable sight blades shaped or adapted to form the respective sides of the sighting notch, or

' having individual notches which may be set in sighting position by adjustment, and in the arrangement and construction of parts as hereinafter more fully described and claimed.

' In the'accompanying drawings comprising a part of this specification, Figure 1 is a side elevation of one modification of a sight embodying our improvements, and which forms the subject of a separate application. Fig. 2 is a rear elevation of the same. Fig. 3 is a side elevation of a sight embodying our improvements in the form which specifically comprises the subject of this application. Fig. 4, is a rear elevation of the same. Figs. 5, 6 and 7 are elevations similar to Fig. 4, respectively showing different arrangements and combinations of the sighting blades and sight notches. Fig. 8 is a vertical cross section on the line a: a Fig. 5. Fig. 9 is a vertical lengthwise section on the line a; at Fig. 8. Figs. 10 and 11 are views of the sight blades removed from the leaf. Fig. 12 is a rear elevation of a leaf sight and its sight blades embodying different forms of notches from those shown in the preceding figures. Fig. 13 a similar view of the sight illustrated in Fig. 12 with the notches arranged to form a different shape of sighting notch.

In the above description of the figures the terms side and rear elevation, cross and lengthwise section relate to the position of the sight when mounted on a firearm, instead of to the actual proportions of the leaf or sight carrying part is hinged.

surface of the base is such that a hinge ear,

d, is provided at each end thereof, in the central vertical lane between the beveled edges, 1). The per orations, 6, through the ears are in alinement with each other and screw threaded to receive the screw studs, f, which are inserted from the outer sides of the ears and are provided with the reduced cylindrical portions, 9, projecting inwardly from the ears or toward each other, as shown in Fig. 9. The said cylindrical portions, 9, comprise the pivots upon which the fChIiing t is common in this class of sights to mount a pair of leaves upon the same axis, in which case, as in the drawing, the main leaf, 72,, may be provided with a pair of eyes, i, fitting be It is to the main leaf that our improvements are shown to be applied, and which are described as follows. The leaf is formed with a horizontal groove, R, extending entirely across its rear face, of dove tailed cross section having the greater width at the bottom, or with the bevel of its sides overhang ing the groove. At the central part of the leaf is a space, if, the depth of which is substantially coincident with the width of the groove. In the groove are fitted a pair of thin blades which are together adapted to form the sight notch, and which may be variously constructed ormodified for different urposes, conditions or eflects. In the modification shown in Figs. 1 and 2 the blades, n, are seated in the same plane at the respective ends of the groove, R, overlapping upon the space, i, and nearly abutting in the central vertical plane of the sight to provide an attenuated slot, 6 or line of light in downward continuation of the bottom or point of the sighting notch, e formed by the inclined configuration of the upper inner end portions of the blades, as shown. This arrangement of the blades forms the subject of a separate application, and therefore will here require no further description, but the construction forming the subject of this application is shown in the remaining figures, the descrip tion of which is as follows, referring particularly to Figs. 3 to 11 inclusive.

The blades, n M, are fitted in the groove, R, of the leaf, one back of the other, that is in two separate planes side by side, the front blade, n, being slightly wider than the rear blade, n owing to the greater width of the bottom of the groove due to its dovetailed form. In length the blades are shorter than the groove or leaf, being about three fourths the length of the groove as proportioned in the drawings and both are made of very thin stock. Each blade has a rhomboidal notch, n near one end, at its upper edge, having the side nearest the adjacent end of the blade forming an obtuse angle with the lower side of the notch, and the opposite side forming an acute angle therewith. Said notches are laced respectively near opposite ends of the blades, or in other words are of right and left handed construction so that the sides of the notches of 'the respective blades are of reversed inclination relatively to each other when in position in the groove of the leaf. In the upper edges of the-opposite ends of the blades are the semicircular notches, n, a of difierential pro ortions, the notch, a in the rear blade, n eing much smaller than that of the front blade, n for obtaining different effects in sighting. The blades are secured in the groove, R, by means of binding screws, "L screwed into screw threaded perforations, '5 in the leaf on the lower side of the groove, in such position that the heads of the screws will impinge slightly upon the lower edges of the rear blade, M, to clamp the blades in their seats. Suitable countersinks, 71 are formed around the perforations, if, to receive the heads of the screws and permit the latter to be screwed down below the surface of the leaf to the extent necessary to insure contact with the blades when the latter are in any degree below said surface of the leaf. In operation, the above described construction of the blades provides four different styles of sighting notch by means of different positions or relation of the blades to each other in the groove, R. These several combinations of the blades and their resultant notches are shown in the Figs. 4 to 7 inclusive, and are as follows. If the ends of the blades farthest from the rhomboidal notches be drawn out flush with the ends of the leaf, as shown in Fig. 7, then thosesides of the notches which form obtuse angles with the bottom thereof will together form a triangular notch, r for the said side of the notch of the front blade, M, will be visible to the eye, through the notch of the rear blade.

By pushing the blades a short distance in toward the central plane of the leaf, the opposite sides of the rhomboidal notches will be brought into juxtaposition as shown in Fig. 6, thus producing a caliper form of notch, 1. With both blades arranged with their ends flush with that end of the leaf which will bring the rhomboidal notch of the rear blade central of the leaf, the semicircular notch, m4, of the front blade, at, will be brought into sighting position, as shown in Fig. 5, while with the blades arranged with their opposite ends flush with the opposite end of the leaf the notch, n of the rear blade, n ,'will be brought into sighting position unobstructed by the front blade, the rhomboidal notch of which will also then be central of the leaf, as shown in Fi 4.

Figs. 12 and 13 correspond to Figs. 7 and 6, but show blades, a n, in which the notches instead of being of rhomboidal form, have one side inclined, and the other of the form of a step, as shown, which produces the triangular notch, 1 of Fig. 7, and the true caliper notch, r as shown in Fig. 13. Various other forms of sighting notch may be obtained, here requiring neither to be shown or described.

The sight leaf, H, is adapted to be folded forward and down to the horizontal position to permit the use of the secondary sight leaf, L, which may then be raised to place. The leaf, L, folds correspondingly down and rearward while the main leaf is elevated, as shown in the drawings. But these features are wholly independent of our invention, which relates to the combination of the grooved leaf and the blades forming the sighting notches of differential configurations. This construction is equally applicable to both folding and non-folding sight leaves or those of any other class.

We claim as our invention.

1. In sights for firearms the combination of a pair of leaves or blades provided with notches of identical form having sides of differential shape, whereby the blades when overlaid upon each other with their notches reversed respectively form the opposite sides of two separate forms of sighting notch.

2. In a sight for firearms the combination of a leaf, and a pair of blades provided with notches of identical form having sides of differential shape secured to the leaf, one overlaid upon the other with the notches relatively reversed and respectively forming the opposite sides of the sighting notch.

3. In sights for firearms, the combination of a suitable supporting element provided with a groove, a pair of blades slidably mounted in said groove and provided in their respective edges with notches of identical form having sides of difl'erential shape, said parts being shiftable relative to each other to place their respective notches in dilferent positions to provide different forms of sighting notch.

4. In a sight for firearms, the combination of a suitable supporting element, a plurality of cooperating sight-forming members, each of which has a plurality of sight elements, said members being movably mounted on said supporting element so that they may be moved With reference to the said element and with reference to each other to produce sighting notches of diflerent form.
