The Lyman rear Wind-gauge sight, shown in Figure so, embodies the same principle of aiming as does the combination sight. A detachable cup, however, is substituted for the small aperture which is in the combination sight. The elevation of this sight is rapid, being obtained by turning a knurled sleeve, which has a triple thread. At every one-fourth revolution of the sleeve a spring snaps into a small notch, which the shooter to quickly adjust the sight. The Wind-gauge operates from the left-handside of the sight. The lower graduated marks show the Wind-gauge. The upper part of the sight folds down forward when not in use. Although the sight folds forward, it is not easy to latock it out of position when shooting, for, unless it is pressed forward more than 90 degrees, it will spring to its place. When adjusting it, screw it to the tang of the rifle as directed for the combination sight. The point blank of the sight is fixed—after testing the rifle at a target—by the adjustable slide on the sight stem.
It is desirable that the sleeve spring should be in one of the notches when the sight is at point blank to prevent the sight from being raised accidentally. This is done by turning the si,ght up out of the sleeve thread anti then turning it back, starting it in one end of the three threads that brings it to the right place when down. It is not often desirable to use the cup, for the large aperture of the sight is much the best even for target shooting.
Referring to Figure 9, "a" shows the Lyman ivory bead front sight. This sight gives the sportsman a clear white bead, which can be seen distinctly against any object, in the woods or in the bright sunlight. The contrasting black neck of the sight makes the bead all the more prominent. "b" shows the Lyman ivory hunting front sight. The ivory is so well protected by the surrounding metal that there is no danger of its being injured. It is a very accurate sight, and many prefer it to any other front sight for all around use. "c" shows the Lyman Jack sight. This is an elegant sight for quick shooting, also in poor light or with the jack at nig-ht. It is very accurate, and fine target shooting can be done when it is used with the tang sights. The Lyman combination ivory front sight is snow-n in Figure it. "4" shows it used with globe, and "e" shows it used with ivory. It is an excellent sight for all around shooting. The sight is shown on the rifle. If it should not be firm enough on its hinge, tighten the right hand screw, which is indicated by the arrow. The Lpnan Wind-gauge target sight is shown in Fig-ure 12, "f" showing aperture, and "h" showing globe. This is an excellent sight for a Match rifle. It has a reversible globe and aperture which can be changed quickly. It is compact in form, being close to the barrel. When set for a g-iven point of wind, it is locked by a spring clamp firmly in position.
"g" shows the Lyman Wind-gauge sporting sight. It is the combination front sight on the Wind-gauge base.
The Lyman leaf sight is shown in Figure 13. One leaf is a bar, with a tri angular ivory. center; the other is a wide open V crotch. Many sportsmen who use the Lyman rear sig-hts do so with the ordinary crotch sight on the barrel. This is much in the way, and the shooting- is done at a great disadvantag-e. Lyman's leaf sight can be put in place of it. It folds down close to the barrel, allowing the shooter to use the combination sight in an unobstructed manner and the result is that the shooting is twice as good as when the ordinary crotch sight is on the barrel. Although the shooter should in any case use the Lyman tang sights for nearly all shooting, he has the satisfaction of knowing that, if he wishes to use this leaf si,ght, that it is the best form of crotch and bar sight in use. The bar leaf is excellent as a twilight sight or when used at night with a jack. The right-hand screw, as indicated by- arrow, adjusts the leaves to fold as tightly as desired.
Lyman's rear sight for Mannlicher sporting rifles is shown in Figure r4. It is a*tached to the side of the arm and is combined with the holt stop. The aperture is on an oscillating arm which allows the bolt of the rifle to pass forward and backward. This arm is adjustable for alignment, being regulated by a screw on the under side. The sight is elevated by turning it around to the left. Any gun smith can put it on the rifle in a few minutes.
The rear barrel sight sh uld be removed. or its stationary, part should be filed off to allow an unobstructed view when aiming. The sight used for target shoot ing at the range and gallery, with hest results, is shown in "k" and "1". It has a reversible aperture and globe, which can he quickly changed. The Lyman re ceiver sight shown in Figure 15 is intended for rifles having a long firing bolt , (like the '95 model Winchester), which prevents the use of the combination rear sig-ht. It is also good on short stocked repeaters which have much recoil. It is very- simple and strong in its construction, and is compact and out of the way. It is made of a flat piece of spring steel, extending along the left side of the ' receiver, toward the grip. The rear part of this plate extends up over the top. On the top of this extension is the sight aperture. The forward elongated hole in the side of the receiver is for the pivot screw. At the rear of the sight is a long slot. A screw is passed through a thumb lever and a spring pointer and through the slot, screwing into the second or rear hole drilled in the receiver. To elevate the sight, turn the thumb lever up, then lock it by turning the lever down. It is not necessary to lock it, however, as the indicator spring,- holds it in position.
