TANGENT SIGHT FOR GUNS.
Specification of Letters latent.
Patented June 23, 1914.
Application filed February 19, 1914. Serial No. 819,789.
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 Tangent Sights for Guns; 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.
In sighting devices for guns the scale divisions are often arranged on a drum instead of on the stem of the tangent sight, the drum being directly or indirectly coupled with the spur wheel engaging the teeth 011 the stem of the tangent sight. When fitting up such an arrangement should the teeth of the stem engage a wrong tooth on the spur wheel, which may easily occur, a wrong scale setting is obtained.
The present invention comprises a device whereby the right adjustment of the stem of tangent sight is insured For this purpose the stem is provided besides the usual teeth with a special lug, which when the stem is rightly set up can engage in a notch in a disk secured to the shaft of the spur wheel, and so make it impossible to set up the stem wrongly, since in that case the lug would strike against the periphery of the disk.
A construction according to the invention is shown in the accompanying drawing: Figure 1 being a side elevation and Fig. 2 a section on line 2-2 of Fig. 1.
The spur wheel a engages in known manner in the teeth of the stem 1). A disk is secured to the spur wheel shaft and has a notch (Z in which, when the stem 6 of the tangent scale is in its correct position, a lug f on the stem can engage.
If the stem is set wrongly, on turning the spur wheel shaft the lug f will strike the periphery of the disk 0 and stop it. A relative movement of the parts is only possible when the stem Z) is so set that when the spur wheel operates the stem, the lug f enters the notch d on the disk 0. The stem b is then in its correct position.
I claim as my invention:
1. In a gun sight having a tangent stem, and a wheel for operating such stem, 00- operating interlocking parts carried by the stem and the wheel for stopping the adjustment of the stem when the latter is improperly set relatively to the wheel.
2. In a gun sight having a tangent stem, and a wheel for operating such stem, a member carried by the wheel having a notch,
and a lug carried by the stem for entering such notch when the stem is correctly set relatively to the wheel.
3. In a gun sight having a tangent stem, provided with gear teeth and a lug, a spurwheel for engaging said teeth, and a disk carried by said spur-wheel and having a notch in its periphery to receive said lug when the stem is correctly set relatively to the wheel.
In testimony whereof, I have signed this specification in the presence of two subscribing witnesses,
KARL VOLLER. Witnesses:
LoUIs VANDORY, GUSTAV PROOKSCHNITZ.
