    Abstract: 1,205,185. Electrically operated lever system for actuating a sliding door. VAPOR CORP. 6 May, 1969 [12 July, 1968], No. 22961/69. Heading E2M. [Also in Division H2] A tube train door 11 is opened and closed by a door operator 10 mounted on a plate 23 within the side wall of the car adjacent the door opening 15. The operator comprises a reversible motor 24, controlled by a circuit 45, Fig. 6 (not shown), mounted with its shaft 25 substantially vertical and drivingly connected to a gear box 26; an output shaft 27 extending from the gearbox; a drive arm 28 secured to the output shaft and rotatable through about 150‹; a crescentshaped connecting link 30 pivoted at 29 to the drive arm; a multiplying lever 32 pivotally mounted on a stub shaft 31 extending from the mounting plate and having a first arm 34 pivoted at 35 to the connecting link and a second arm 36 pivoted at 40 to a connecting rod 41, which is pivoted at 42 to a bracket 43 on the door. When the door is in the closed position (corresponding position of components of operator shown in solid line) the drive arm 28 abuts against a stop 53 so positioned that the pivot 29 is over-centre w.r.t. pivots 27 and 35 thus locking the door. An emergency release handle 63 may be mounted on the plate 23 for manually driving the pivot 29 back over centre to permit the door to be manually opened (see Fig. 2). Operation of this handle opens a normally closed switch (66, Fig. 2) preventing energization of the motor during manual operation of the door. Cam means may be provided on the multiplying lever 32. to operate a switch to cushion the end of the door opening cycle and a switch to de-energize the motor at the end of the door opening cycle. The drive arm 28 operates another switch at the end of the door closing cycle to de-energize the motor.

    Abstract: A door system for a railway passenger car which accommodates both high and low level boarding platforms includes a sliding upper door for both high and low level boarding, a segmented lower door immediately below the upper door for low level boarding, and a staircase connecting the floor of the car to the lower door opening. The staircase is covered by a segmented sliding floor panel during high level boarding, and the sliding floor panel and lower door are retracted to fully enclosed positions under the staircase during low level boarding.
