Abstract

665,816. Substation equipment. COMPAGNIE GENERALE D'ELECTRICITE. July 3, 1946 [July 5, 1945], No. 19886/46. Class 40 (iv). [Also in Group XL (b)] A subscriber's number sender transmits numbers in a four-unit telegraph code. Depression of a key 1 operates a rack-and-pinion device 9, 36 to wind up a spring 32 housed in drum 33. During the latter part of the motion of the key depression of bar 3 causes a member 35 to rotate about a pivot 4 so that a bar 7 moves to lock the depressed key and prevent depression of any other key. Movement of bar 3 also withdraws locking members 24, 28 from the four slotted code bars 8 so that those not restrained by the depressed key are moved by springs such as 25 to close corresponding sets of contacts 38. Contact 39 is operated on each depression of a key to change over the line connection from the telephone set to the impulse transmitter. Member 35 acts on the extension 34 of a member having a catch 17 which releases the drum 33 to turn the shaft 37 under control of an escapement mechanism operated by vibrating reed 13. The shaft 37 rotates the wiper 10 over segments 11, the second of which is disconnected, the next five being respectively connected to line over contact sets such as 38 and the last contact directly to line. When the drum 33 has made a full revolution its projection 31 engages a catch 15 to restore the parts 34, 35, the equipment then reverting to normal under control of springs 23, 26.
