Abstract

249,419. Newey, J. G., and Jerred, C. B. Oct. 5, 1925. Wireless tuning-apparatus and resistances, ad. justment devices for.-Worm and segment gearing for coil-holders &c. in wireless apparatus is provided on the toothed segment, or a part moving therewith, with a rigid stop member which, at the ends of the segment's travel, abuts against a projection on the worm or worm spindle. As shown, a metal plate h secured to the segment e is provided with lugs h', h<2> which, in one limit position of the movable coil-holder c, engage behind the pin j and in the other limit position in front of the pin j, the pin projecting radially from the worm spindle f.
