Abstract 907,003. Latches. TRICO PRODUCTS CORPORATION. Sept. 19, 1958 [Sept. 23, 1957], No. 9849/62. Divided out of 907,002. Drawings to Specification. Class 44. The subject-matter of this Specification is substantially the same as that described in Specification 907,002, but the claims are concerned with a motor vehicle having a door lock controlled by a fluid-operated servomotor, and a valve comprising a valve element controlling a pressure or vacuum supply for operating the servomotor and connected to a diaphragm which partly defines a control chamber and which is urged by a spring in one direction, the control chamber being arranged to communicate with a source of pressure or vacuum which is generated by the engine of the vehicle while the engine is running and which moves the diaphragm against the action of the spring and thus moves the valve element so as to operate the servomotor and lock the door when the engine is started.
AN AUTOMATIC LATCH LOCKING SYSTEM FOR THE COMPULSORY LOCKING OF DOORS OF A MOTOR VEHICLE BEFORE THE VEHICLE IS SET IN MOTION BY ITS PROPELLING POWER PLANT, COMPRISING AUTOMATICALLY OPERATING PLURAL LATCH LOCKING MECHANISMS, EACH INCLUDING A DOOR LATCH AND A LOCKING MEMBER THEREFOR MANUALLY OPERABLE FROM WITHIN THE VEHICLE TO FREE THE LATCH FOR OPENING THE RESPECTIVE DOOR BY ONE OR ANOTHER OF PLURAL OPERATORS, ONE OF SAID OPERATORS BEING COMMON TO ALL DOORS, AUTOMATICALLY ACTING FLUID POWER VALVING MEANS CONTROLLED BY SAID ONE OPERATOR AND HAVING A PRESSURE SUPPLY, A POWER MEANS FOR EACH DOOR HAVING A MOVABLE WALL RESPONSIVE TO DIFFERENTIAL FLUID PRESSURE ON THE OPPOSITE SIDES THEREOF FOR MOVEMENT OF AND OPERATIVELY CONNECTED TO THE RESPECTIVE LOCKING MEMBER FOR SECURING ITS LATCH AND THEREBY IMPOSING A COMPULSORY LOCKING OF ITS DOOR AUTOMATICALLY THROUGH SAID VALVING MEANS WHILE CONDITIONING THE VEHICLE FOR OPERATION, AND FLUID CONDUIT MEANS CONNECTING SAID VALVING MEANS TO EACH OF THE PLURAL POWER MEANS, SAID POWER MEANS BEING NORMALLY UNDER BALANCED PRESSURE ON OPPOSITE SIDES OF SAID MOVABLE WALLS TO PERMIT THE FREE MANUAL OPERATION FROM WITHIN THE VEHICLE OF THE RESPECTIVE LATCH LOCKING MEMBERS.
