Improvements in, or connected with, Safety Locks for Railway and other Carriage Doors and the like.
Реферат: 28,652. Lewis, G. Dec. 11. Multiple fastenings for railway carriage doors; latches, sliding. - A spring safety latch 3 mounted in the door framing near the top of the door is pressed back by the sliding bolt 8 when the door is to be opened. The bolt 8 is operated, through the bell-crank 13 and wire or cable 16, by the part 19 sliding in the curved guide 21. On the outside handle 22 is mounted a trigger 24 controlled by a spring 26. To open the door, the handle 22 must be turned to disengage the ordinary lock or fastener; at the same time, the finger-piece 25 must be held down, so that the trigger 24 catches the part 19 and moves it along the slot 21, causing the release of the safety-latch 3.
