Abstract
225,597. Wright, E. H., and Hodgson, F. Aug. 9, 1923. Rotary distributors ; switches, actuating.-A distributor for successively switching tuning elements of a wireless transmitting or receiving system into and out of circuit comprises a continuously driven arm i carrying brushes i<2>, i<3> which co-operate with the pairs of contacts g<1> - g<5>on a base h to successively switch into and out of circuit the tuning element; ac. The base h of the distributor may be adjusted by a worm j provided with a handle j<1>The arm i is mounted so that it may be clutched to a continuously rotating spindle. The arm is freely mounted on a spindle p, Fig. 2, has a head p<1> provided with ratchet teeth. When depressed. the spindle p is clutched to a driving spindlen by a catch n<1> and the teeth on the head p<1> engage similar teeth on the boss of the arm i. In alternative forms, each distributor may comprise a drum having contacts which engage wiping contacts or a member which is reciprocated or oscillated over contacts.
