729,418. Latches. FORD MOTOR CO., Ltd. Dec. 9, 1953 [Dec. 9, 1952], No. 34286/53. Class 44. [Also in Group XXXVIII] A latch mechanism for mounting on a vehicle door has on a flange 12, Fig. 1, of an L-shaped mounting 11, a rotatable bolt rotor 16 connected by a shaft 17 to ratchet wheel 18, controlled by a pivoted spring pressed pawl 31 which is coupled by means of a pin 41 and slot 39 to a manually operable pivoted lever 29 to release the bolt on moving the upper end 37 of lever 29 to the right by an exterior door handle or push button (not shown), A pivoted locking lever 43, operable by an external key actuated lock (not shown) or by means of an interior door handle (not shown) having a flange 46 which engages a flange 47 on the lever 29 to block its movement to release the bolt. Flange 13, Fig. 2, pivotally mounts a bell crank lever 61 connected by stud 66 to a link and inside remote control handle (not shown) and on anti-clockwise rotation of the arm 63 engages arm 33 of the pawl 31 to release the bolt and at the same time, lug 71 on arm 68 engages arm 57 of an intermediate lever 53 connected by fork 52 to arm 49 of the locking lever 43, to disengage the locking lever 43 from the release lever 29 unless this is already in the unlocked position. Conversely, clockwise rotation of the bell crank 61 causes lug 72 to move the parts to the locked position. The brightly painted end 76 of lever 53 is, in the locked position, visible through an aperture in the inner door panel (not shown). The rotor 16 engages a toothed keeper (Fig. 3, not shown) rigidly mounted on an adjacent door pillar, and also formed with a housing into which a dovetail 24, shown in dotted outline in Fig. 1, engages with a spring pressed slidable wedge.
