Abstract

464,334. Substation equipment. TELEFONAKTIEBOLAGET L. M. ERICSSON. Oct. 15, 1935, No. 28406. Convention date, Oct. 23, 1934. [Class 40 (iv)] [Also in Group XVIII] A coin-box arrangement is such that a coin, which may be inserted at any stage during the establishment of a connection, remains at the top of the shoot (in position I) so that it may be recovered directly if the call is ineffective. If the call is successful, a relay R1 responds to the reversal of current when the called party replies to short-circuit the speaking instruments and to withdraw the stop S 1. The coin thereupon falls to position II in which it closes contact K to short-circuit R1 and restore the speaking circuit. The coin is collected by the operation of a second relay R2 when an incoming or another outgoing call is made. The contact K may be only' momentarily engaged by the coin in passing in which case it is mechanically locked until released by R2. The arrangement may be adapted to deal with calls requiring more than one coin of the same or different values.
