Abstract
602,014. Latches. INGERSOLL, Ltd., YOUNG, L. W., and TAYLOR, J. W. Sept. 6, 1945, No. 23011. [Class 44] In latch mechanism of the kind in which a latch in the form of a slotted plate co-operates with a staple in the form of a pin, the latch plate is mounted to slide in guides in a direction transverse to the direction in which the latch and the staples approach one another and the slot in the latch is inclined to both these directions so that when the pin meets either edge of the slot it will exert a camming action on the latch, moving it in one direction or the other to either the latching or unlatching position. In the form shown in Fig. 1 the latch comprises a plate 6 sliding vertically in a casing 1 on the door, the casing having a slot 3 for entry of the pin 4 on the door jamb. A slot 9 is formed in the latch plate 6 at an angle of approximately 45 degrees to the direction of sliding. As the door is closed, the pin 4 enters the slot 9 and cams the latch upwardly against gravity or against the action of a spring 8. A sliding bolt is then urged into position below the latch plate by a spring 12, a handle 13 being provided for retracting the bolt 11 to unlock. The upper edge of the bolt 11 and the lower edge of the plate 6 are preferably bevelled to prevent rattle. In the form shown in Fig. 4, the locking bolt 11 is withdrawn by a follower 18, and to dead lock the latch an auxiliary bolt 21 is provided, actuated by a key lock operating a cam 22 which moves the bolt 21 to the position shown to lock. Figs. 6 and 9 show modified forms.
