Title: Improvements in latches for doors, gates and the like
IPC: E05C1/16
Filed: 1919-04-14
Abstract: 145,192. Kellerman, H. R., and Fletcher, H. P. April 14, 1919. Latches, sliding; reversible latches.-Relates to a latch for motor-car or other doors &c. operated by a lever handle which can be detached and reversed, rendering the latch suitable for a righthand or left-hand door. In the construction shown in Fig .1, the lever 4 acts on the cross-piece 5 to withdraw the latch against the action of the springs 6. The lower end of the lever has an open slot 16 by which it engages one of the pins 12, passing behind the head 13. Accidental upward movement of the lever is prevented by the projection 17 engaging in the slot 18 in the crosspiece 5. For reversal for a door of opposite hand, the latch bolt 4 is pressed inwards until the lever 14 can be withdrawn, to be re-inserted with the slotted end 16 engaging the second of the pins 12 as indicated in dotted lines. In the modification shown in Fig. 3, the crosspiece 5 is dispensed with and the lever bears on the cam-block 20. The mouth 22 of the slot 21 in the end of the lever is narrowed so that force is necessary to withdraw it from engagement with the pin 12. In this form of latch, when the lever is reversed on to the upper pin 12, the latch 4 with its spring 6 is moved down to the lower pair of holes in the flanges 2, 7<a>. This arrangement, by lengthening the distance between the pivot and the point of contact of the lever, enables a smaller movement of the handle to give the required throw to the latch. In a modification shown in Fig. 5, the lever 14 has two projecting portions with forwardly-opening slots 23, 24 engaging the top and bottom pins 12. This form has the advantage that the latch can be operated by a movement of the handle in either direction from the central position.
