Gustav Appel company in Berlin-Spandau deep fire spreading device

Patented in the German Empire by the ji. February τ 0.33 from

The invention solves the problem of delivering Tiefenfeiter with an automatic weapon, which is kept exactly within the desired limits by a device, which swings out the barrel of the weapon in the vertical direction while maintaining the limits that can be set on the device of the angular deflection. Various systems have become known to help with dispensing from so-called deep fire the movements of the rifle up or down, d. H. so the pivot angle of the weapon in the vertical direction within precisely defined Limit values. The known devices consist for the most part in handwheels, the rotation of which by means of index pins or adjustable stops is limited. hi usually the axis of the acts Handwheel on a worm gear, from which the movement affects the weapon transmits (Fig. 1). With the usual mounts there is between the rifle carrier and the Leveling machine inserted a special straightening joint, its location and position to the rifle carrier at different elevations of the mount is different. In the known arrangement of the height limiter on the handwheel shaft now results in this respect a disadvantage, as the twist angle of the weapon is not always in the same ratio to rotate the handwheel, because the lever of the straightening machine in one case is close-up

Fig. Ι shows the lower part of one of the most common mounts with straightening spindle 0, straightening joint b, handwheel shaft d and straightening

is too perpendicular to the straightening device, in the other case an angle of almost 180 ° with the Directional joint forms. It is obvious that the lever arm in the vertical Position with the same adjustment of the handwheel a larger deflection on the rifle carrier emelt than with an angular position of almost 180 ° between the right machine lever and straightener. From this it follows that the angular deflection is inevitable the weapon in the vertical direction in the individual elevations of the mount each different is because the angle of the straightening joint and the straightening machine lever changes. However, since the stops on the handwheel only turn the handwheel the same permit, surrender at school! extraordinary mistakes.

The present invention now avoids the errors outlined above by arranging a special device, which the connection between the Rifle carrier and the aiming joint and which represents the change in the firing angle by bringing the gun carrier on a special, later closer described curve leads.
