Title: Improvements in railroad interlocking plants

Abstract: 357,465. Railway signal electrical interlocking plant. TELEFONAKTIEBOLAGET L. M. ERICSSON, 33, Kungsgatan, Stockholm. Jan. 31, 1931, No. 3195. Convention date, Feb. 20, 1930. [Class 105.] In an electrical interlocking frame in which the look magnet of a lever is released over a series of contacts of the levers interlocking therewith, a fault relay is connected in the circuit so that the lock magnet is disconnected or shunted when the fault relay on account of leakage is unable to attract its armature. The Figure shows the circuit for a points lever, the fault relay 12 and its armature 13 being at the two ends of a line of contacts 7 .. 11 of which 7, 8, 9 are contacts of the levers interlocking therewith, 10 a contact automatically opened when the train is approaching to prevent operation of the points, and 11 a contact closed when the points lever is pulled out axially to move the lever. The contacts 18, 19 are respectively closed in the normal and reverse positions of the points. On closure of the contact 11 the fault relay 12 is energized over the line 24 and resistance 20 to attract its armature 13 and energize lock magnet 4 over a contact 14 so as to permit movement of the points lever to a position closing a contact 15 ; as the points contact 18 is closed the lever can be moved past this position to energize the points motor. When the points have moved over and closed the contact 19 the lock magnet 5 is energized over a contact 16 to permit movement of the lever past the position in which it closes the contact 16. If a leakage occurs such that battery positive is applied say at a point 21, then the fault relay 12 is not energized ; if the leakage is such that battery negative is applied then the lock magnet 4 (or 5) is not energized. The fault relay armature 13 instead of disconnecting the lock magnets 4 or 5 may shortcircuit them, being for example inserted in the line 24 the resistance 20 in which is then omitted.
