Abstract: 642,545. Permutation locks. PHILO O. July 3, 1947, No. 17571. Convention date, Dec. 5, 1946. [Class 44] A permutation lock comprising a number of discs each of which has to be set to a predetermined position before the latch bolt can be retracted, has means for scattering the discs in different directions when the bolt is projected. A number of independently rotatable discs 25, mounted on a common axis inside a door 2, have deep slots 28 which must be aligned with a tongue 24 before the latch can be retracted. The latch bolt 8 is normally held projected by a pair of springs 11, 12, housed in gaps 13, 14, of the bolt between the ends of the gaps and upstanding posts 15, 16, on the interior of the door 2. A handle unit 17 comprises a handle 23 for retracting the latch bolt, a stem 18 which is slidable between shoulders 19, 20, on the bolt and whose end forms the tongue 24, and a head 21 which slides in the gap 53 in the bolt. The interior discs 25 are rotated by corresponding exterior ones 31, each pair being connected by a divided hub portion, the two parts of each hub being connected by cooperating sets of teeth. The tail of the latch bolt is formed as a plate 44 having a slot 45 through which passes the bolt on which the discs rotate, the plate being provided with two L-shaped angle brackets 46.for housing pawls 51, each of which corresponds to one of the discs 25. The discs 25 have numerous shallow slots 29 on their peripheries to hamper picking of the lock by feeling and after the deep slots 29 have been aligned with the tongue 24 and the bolt retracted by the handle 23, each of the pawls 51 is pressed by its spring 52 into engagement with one of the discs. When the handle 23 is released, the springs 11, 12, project the bolt, and the pawls 51 rotate the discs to scatter them, the pawls being so arranged that with the bolt fully projected the pawls are held just above the discs 25. Sufficient lost motion between the latch bolt 8 and the handle 23 is provided so that when the chamfered edge 54 meets the striking plate on closing the door, the latch bolt may be forced back against the action of springs 11, 12. On the bolt springing into its socket the discs are scattered once more by the pawls 51 engaging the slots 29. For changing the combination after the door has been opened, the latch bolt is held retracted, the bolt holding the discs together has its screw loosened from inside the door, and the bolt head 37 is pulled outwards. The sets of teeth on the divided hubs are separated, the exterior discs rotated, and the teeth re-engaged. The bolt head 37 is then pressed inwards and its screw tightened.
