WW1 in Alsace - Linge Battle - 63rd Anti Aircraft Regiment - 96th poste semi-fixed
Short extract of an artillery trainning course - by unknown author and date.
The platform includes a frame, consisting of 2 triangular lateral trusses ABS, A'B'S', arranged vertically, and suitably braced.
The plans of the farms are vertical, and form an angle of approximately 30° with each other.
The vertical uprights have, at their upper end, sub-strips SS' intended to receive the axle of the gun carriage.
The lower spacer AA' carries a vertical pivot.
Each door closer has a large cast iron roller on its rear part.
The frame is placed in a circular pit in the center of which is securely installed a saddle with a pivot in which the vertical pivot of the frame can turn.

Around the perimeter of the pit, an iron roller ring is fixed, on which the 2 rollers of the trusses rest.
The 75 Model 97 gun, stripped of its wheels, shields, and wheel brakes, rests by its axle on the sub-bands of the uprights. The boom, which passes through the recess in the floor, is supported by a cable attached to the butt sight; this cable is wound on a T-shaped winch mounted on the frame.
Directional aiming: by rotating the frame and the cannon around the vertical pivot, the rollers roll on the circular track; for this purpose, the platform, P' carries a flywheel which, by means of transmissions, actuates the roller G'.
For large-amplitude movements, the frame is pushed by hand.
Champ : 360°.

The direction pointing device is carried by the right-hand truss (Model 97 pointing device on its support, the latter being mounted on a pivoting base allowing it to be given the inclination corresponding to the site of the objective).
Height pointing: large rapid de-icing by rotation around the axle by winding or unwinding the cable on the winch T; the rotation of the latter is controlled by a handwheel carried on the platform P. The pointing handwheel carried by the mount (1) can also be used.
Pour les déplacements de grande amplitude, le bâti est poussé à bras.
(1) The riser drum is replaced by a drum graduated in thousandths.

The firing is carried out in accordance with the instructions of the note of April 22, 1915 on the organization of the firing of the 75 cannon against aerial targets.
Transport : Army equipment; the 1915 model platform is transported disassembled on 2 trucks.
The battery can be installed in approximately 2 hours.
When no travel is planned, the pit is lined with concrete.
The 75mm DEPORT system cannon was also used against aerial targets (see: Italian Artillery)
