461,778. Door fastenings. WELLS, G. W. March 6, 1936, No. 6877. [Class 44] In a door fastening for automobiles and the like a lug 22, Fig. 12, is rigidly attached to the door and fitted with a latch 40, which engages a movable striking bar 62. The latch 40 guided by rods 42 is operated by a cam 28 formed by a recess 27 in a shaft 26 which is rotated by a plate 30, Fig. 3, fitted with lugs 31, 32. The lug 31, Fig. 2, is actuated by an arm 38 rigidly attached to a handle 35. Normally the latch is held in engaging position by spring 50, and the handle by spring 59. The lug 32, Fig. 9, is operated by the arm 54 which is controlled from the inside by handle 57 through the levers 52, 55, and when the handle is pushed to the fullest extent the tooth 58 locks the plate 30. The striker consists of a rectangular casing 60, Fig. 12, with base 61 fitted with ramp at inlet end so that when the lug 22 engages the face 61, the top surface of latch 40 engages teeth 65 of the bar 62 and swings it forwards and upwards, any tendency for the door to open will cause the teeth 65 under action of spring 63 and rigid members 64 to bite into surface 40. In a modification the striking bar is replaced by a number of pawls loosely mounted in spaced relation at one end on a rod, the opposite end engaging the face of the latch.
