Abstract

207,797. Hammarlund, L. A. Nov. 28, 1922, [Convention date]. Condensers.-In a variable condenser provided with means for giving a coarse and fine adjustment, the fine adjustment is effected by the agency of an arm 20 frictionally engaging the spindle 11 on which the movable vanes are mounted. One end of the arm is provided with a clamp 21, the branches 22, 23 of which are drawn into the required frictional engagement with the spindle by means of a screw 24. The other end of the arm is provided with a yoke 25, with branches 26, 27 engaging an eccentric cam 28 mounted on a shaft 29 provided with a handle 30. The coarse adjustment is effected by rotating the spindle by means of the usual operating-knob 12, and the final fine adjustment is obtained by means of the handle 30.
