摘要
The elevation gear is disengageably mounted on a traversable sub-structure, and includes a threaded spindle rotatably mounted on a support and two plungers mounted in laterally spaced relation on the support for displacement upwardly and downwardly, the plungers serving as supports for the firing device. Abutments on the support between the plungers are disengageably cooperable with the firing device to serve as a pivot axis for elevational displacement of the firing device. A play-free transmission interconnects the spindle and the plungers and is operable, responsive to rotation of the spindle, to displace the plungers simultaneously in respective opposite directions. The transmission comprises two nuts threaded on the spindle and each connected to a respective lever, with each lever engaging the lower end of a respective plunger. The free ends of the levers are inclined and ride on respective rollers so that, when the nuts are displaced longitudinally by rotation of the spindle, the free ends of the levers are moved upwardly or downwardly. The plungers have rollers at their lower ends engaging the respective levers, and the upper ends of the plungers engage rollers on the firing device. One of the plungers is spring loaded. An elevation indicator is articulatedly connected to one of the nuts.
