JOHN TAYLOR PEDDIE, OF WESTMINSTER, LONDON, ENGLAND.

SIGHT.

To all whom it may concern:

Be it known that l, JonN TAYLOR Pnnnm, a subject of the King of Great Britain and Ireland, residing at Oaxton House, Westminster, London, S. l/V., England, have invented new and useful Improvements in Sights, of which the following is a description.

My invention relates to sights used upon firearms, and more particularly to the type of sight in which it is desirable to attain a line vertical adjustment of the cross bar by aid of a screw. Generally speaking, in this type of sight, a long screw is employed, and ordinarily it is impossible because of the slow movement of this screw and all parts actuated thereby, to obtain a coarse and rapid adjustment of the cross bar as, for instance, by sliding it quickly by a direct movement of the hand.

The object of the present invention is to enable the operator to obtain, independently of each other, two distinct adjustments of the cross bar; one being made by a rapid or coarse movementy of the cross bar when pressed directly by hand, the other being a fine adjustment which is effected by aid of a screw.

A further purpose of my invention is to provide a construction of sight in which the screws and various other delicate parts are suitably inclosed and thus protected against the action of grit, sand and dirt.

The invention is applicable to the various forms of sight wherein a cross bar is adapted to slide upon a leaf to elevate the latter for short ranges, the cross bar acting as a V- sighting piece when the leaf is arranged in an `upright position for long ranges, the cross bar being held in the adjusted positions by friction alone or by a pawl or pawls engaging in racks or within the edges of the leaf.

My invention comprises means for mounting a cross bar on the leaf of the sight so that it can be readily slid thereon to permit rough or independent adjustment, in providing a screw at the end of the leaf and in suitably connecting the screw with the cross bar, so that the latter, although free to move independently of the screw in order to make the coarse adjustment, is nevertheless controllable by the screw for purposes of the finer adjustment.

The invention also comprises the combination, with the leaf fitted as aforesaid, of a double cross bar as hereinafter described.

Specification of Letters Patent.

Serial No. 433,682.

The accompanying drawings illustrate several modes of carrying out the invention.

Figure l is a side elevation of one form of the sight; Fig. 2 is a plan view of the same; Fig. 3 is an end elevation of the sight as it would be viewed from the left of Fig. 2; Fig. 4 is a side elevation of another form of the sight complete; Fig. 5 is a plan view of the construction shown in Fig. 4; Fig. 6 is a detail, showing an end view of the leaf; Fig. 7 is a cross-section upon the line A-B of Fig. 5, looking toward the left; Fig. 8 is a side elevation of still another form of the sight; Fig. 9 is a plan view of the same; Fig. 10 is a cross-section upon the line C-D of Fig. 9, looking toward the right; Fig. 11 is a fragmentary section showing fragmentarily still another form of the sight top, and Fig. 12 is a cross-section through the construction shown in Fig. 11.

In carrying out the invention according to one mode as illustrated in Figs. l to 3, the usual rectangular frame type of leaf, a, has one side (the lower side, according to Fig. 2) of the frame somewhat narrower than usual. This side is made up to the usual Width by the addition of a bar, (hereinafter referred to as a connecting member) which fits closely against the side and has an outer edge adapted to form the usual edge engaged by the cross bar, c, being plain or toothed accordingly as the cross bar is held by friction or by a pawl. ln the example shown the edge of the connecting member, t, is merely roughened or slightly serrated and a spring pawl, d, is used on the cross bar for the purpose of holding the cross bar temporarily in position previously chosen by the operator. One end of the connecting member l) is provided or formed with a pin, e, to engage in a small hole in the end of the leaf near the hinge f, while the other end, g, is adapted to receive a screw, 7L. The screw, 7L, passes through a hole in the end of the leaf, a, and has a milled head, l, let into a suitable recess, and a collar, i, engaged by a pin, Zi', to allow of rotation but to prevent removal. The cross bar, c, engages the leaf, a, on one edge as usual but on the other side engages the edge of the connecting member, b, so that while the cross bar can be readily slid along the leaf and given a coarse adjustment, it can also be finely adjusted by slightly sliding the connecting member by rotating the milled head, l.

Obviously the leaf may have two connectg1g 922,945 y ing members l) l), made movable as illustrated in Figs. 4 to 7 in which case they may be united at one end by or be made integral with a cross piece, m, having a single central threaded pin, h, having a milled head, Z, and collar, t', held by a retaining pin, 7c, or it may be moved by any other suitable screw arrangement. In this case both connecting members are shown of half round section'fitting corresponding grooves in the edges of the leaf, a, the outer edges being serrated, the cross bar having two pawls, d. rlhe cross bar also has the usual wind-gage adjustment. Instead of a screw engaging a threaded hole in the end of the connecting member (Fig. 2) or in a cross piece, m, (Fig. 5) the obvious mechanical alternative may be used, viz., a screw may bei formed on or secured to the latter parts and' be engaged by a nut free to revolve but not to move axially, in a manner similar to that of the milled head, l and collar, c.

rIhe cross bar used may be of any of the usual forms but it is preferred to make it,

with one ortion or e evating bar running across the eaf and fitted with the usual gripping devices, and with another bar having a V cut in its edge to act as a sighting bar for long ranges, the sighting bar being connected to the elevating bar by short side portions so that there is a space between the two bars. A V may also be cut in the edge of the elevating bar itself to suit a different set of ranges.

The elevating bar in this form is preferably flat and thin in form. Such an arrangement is shown in Figs. 8 to l0 wherein c represents the elevating bar having two sighting notches, n and o, and the usual wind-gage adjustment, and s the auxiliary sighting bar for long ranges also having a V or sighting notch, p. The bar s, shown by way of example is fitted with ratchets or pawls adaptedv to be disengaged by buttons, q, and to engage teeth r, in the portions, l) l), under the action of springs in the known manner. The V or notch, n, is to be used for the lowest series of ranges, o, for the next series and p, for the longest series of ranges. It is to be understood that so long as the relatively movable connecting member or members, b, between the screw, h, and the cross bar permit of independent movement or adjustment of the cross bar and yet effect line adjustment thereof in the manner described they need not necessarily be on the edge or edges of the leaf but may be on top, below or embedded therein, for instance, as indicated in Figs. 1l

and 12, the lettering in these parts corresponding to the lettering in the other figures.

Having now fully described and ascertained my said invention and in what manner the same is to be performed I declare that what I claim is 1. In a sight having a hinged leaf and a sliding cross bar thereon, the combination of a screw, two connecting members, a cross piece connecting the latter and carrying the screw, a screw hole in the leaf for receiving the screw and means for connecting the aforesaid cross bar to the connecting members for the purpose hereinbefore set forth.

2. In a sight having a hinged leaf and a sliding cross bar thereon, the combination of a screw, two connecting members, grooves in the leaf for receiving said members, a cross piece connecting them at one end and carrying the aforesaid screw, a screw hole in the leaf for receiving the screw, and means for connecting the aforesaid cross bar to the connecting members, for the purposes hereinbefore set forth.

8. In a sight having a hinged leaf and a sliding cross bar thereon, the combination of a screw, two connecting members having serrated edges and of half round cross section, grooves of corresponding form in the edges of the leaf for receiving said members, a cross piece connecting them at the one end and carrying the aforesaid screw, said leaf being provided with a screw hole for receiving the screw, and pawls carried by the cross bar and engaging the serrated edges of the connecting members substantially as and fer the purposes hereinbefore set forth.

4. In a sight having a hinged leaf and a sliding cross bar thereon, the combination of connecting members, means for moving said members relatively to the leaf, means carried by the said cross bar for connecting the' latter to said members so as to permit independent movement of said cross bar, and an auxiliary sighting bar connected with the cross bar, both the latter and the auxiliary bar having sighting notches, substantially as and for the purposes hereinbefore set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
