GUN-SIGHT.
Application filed November 18, 1911.
To all whom it may concern:
Be it known that I, KARL VoLLER, engineer, a subject of the German Emperor, residing at 12 Scharnhorststrasse, Dusseldorf, Germany, have invented certain new and useful Improvements in Gun-Sights; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
The present invention relates to sights for guns in which the firing charge can be varied; the sight is constructed so that any efiect due to the difference of level of the wheels and also the lateral deviation (drift) of the projectile due to the rifling which deviation varies with the charge are exactly compensated at all elevations. This result is obtained by the arrangement in which the gun sight can be turned on the sight bar about an axis parallel to the line of sight, while the sight bar is capable of rotation about an axis parallel to the axis of the gun barrel. This allows the telescope to be set at an angle on the sight bar, depending on the deviation produced by the variable charge, which angle is read ofi on a scale placed between the head of the sight bar and the sight carrier. WVhen the latter is set on the sight bar to the scale reading corresponding to the charge used, the sight bar must be inclined until a spirit level, at right angles to the axis about which the sight carrier turns, is horizontal. In this way the drift of the projectile can be compensated for the charge used for every elevation and range.
The three figures of the accompanying drawing illustrate a sighting device according to the invention in which two sights independent of each other are combined, Figure 1 being an elevation; Fig. 2 a similar View at right angles to Fig. 1; and Fig. 3 a cross sectional view on line 33, Fig. 1.
One sight consists of a telescope (panorama telescope) arranged in known manner on the sight bar, and the other is either a small telescope or a so-called collimator.
The sight bar a is arranged in known manner to slide in the sleeve 6 and can be set in this sleeve by the milled head screw 0 according to the sight angle of elevation,
which is read off on the scale (Z. The sight Specification of Letters Patent.

bar is curved in the arc of a circle, whose center lies near the surface of the gun shield s.
The head 6 of the sight bar a is provided with a circular groove in which the sight carrier f slides, and can be adjusted in a vertical plane at right angles to the axis of the gun barrel. The setting is effected by a worm gearing or the like by turning the milled head screwy.
,--""The sight carrierf is provided with a *1 p anorama telescopeb and also carries a second sighting device, a so-called collimator 2', which can be adjusted independently tr the telescope h laterally in a horizontal plane. For this purpose it slides on a circular guide 70, whose center lies in the surface of the shield s (Fig. 3) and is set by the worm milled head screw m to a reading on the scale a. A spirit level 0 is also provided on the sight carrier. 1
The sight bar sleeve 6 is j ournaled on an arm 29 fixed on the barrel or on the cradle, so as to be capable of rotation about an axis parallel to the axis of the gun barrel. The sleeve 6 has a hook formed extension surrounding a circular guide 9 of the arm p and is guided on a suitably formed member 7", which is curved in an arc struck from the same center. Any required setting can be given to the sight bar sleeve 6 by a worm gearing operated by the milled head screw 25. This adjustment is provided to compensate for any difference of level of the wheels and the lateral deviation of the projectile produced by it. Between the head c of the sight bar a and the sight carrier f a scale at is provided with divisions, of which one corresponds to the central position of the sight bar a; with respect to the telescope it, in which position both are in the same plane. The other divisions determine the different angular positions of the sight bar with re-- spect to the telescope, which correspond to the deviation of the projectile at different charges.
On firing, the sight carrier 7 is set on the head 6 of the sight bar a to the reading corresponding to the charge used. The sight bar sleeve 12 is then tilted by turning the milled head 6 until the spirit level 0 on the sight carrier f is horizontal. The axis of the telescope h and also of the collimator i about which they are turned for the purpose ill? of giving the lateral deviation Will always therefor mounted on the sight bar, and then lie in a vertical plane, While the sight means connecting said carrier and said bar 5 bar a, and the sleeve 6 are inclined to the permitting the turning of said carrier about vertical by the angle previously set on the an axis parallel to the line of sight, and a 5 sight carrier, so that on raising the sight bar spiriLlegel, mounted on said carrier at right a the lateral deviation is compensated. angles to the latter axis.
