Abstract
230,274. Wilkins & Wright, Ltd., and Hewitt, J. H. March 18, 1924. Condensers.-In a variable condenser having two sets of independently - operated movable vanes for coarse and fine adjustment respectively, a pair of spring arms are provided, each bearing on one set of plates for retaining them in adjusted position. The fixed vanes 3 are assembled with spacing washers on pillars 2 uniting metal end plates 1, and the main set of moving plates are mounted on a spindle 6 operated by a knob 20 and adjusted axially by a screw 11 provided on the lower end plate. One or more moving vanes 13 for giving fine adjustment are secured to a sleeve surrounding the spindle 6 and adapted to be rotated by a lever 18. Both sets of moving vanes are accommodated between the end plates 1, and the upper plate serves as a fixed vane co-operating with the moving vanes 13. The spring arms for retaining the moving vanes in adjusted position are formed from a single phosphor-bronze strip 7 bent at 9 as shown, and provided with a lug 14 serving as a stop co-operating with stops 15 provided on one of the spacing washers on the spindle 6. Specification 214,363 is referred to.
