Abstract: 25,086. Soley, F. Nov. 7. Locks, permutation.-A permutation lock for doors and furniture drawers is so arranged that the blocking-disks can be adjusted either by the sense of sight alone, or by the senses of hearing and touch, with or without the sense of sight. The bolt 32, Fig. 2, is operable by a tooth 27 on the follower 26, which can be turned by a knob 4, through the intermediary of disks 20 and a lever 36 pivoted to the follower. Normally, the lever 36 is out of engagement with notches 22 in the disks 20, and the follower 26 is prevented from turning by a flange 37 of the lever 36 bearing against a rib 39 on the casing. The disks 20 are set by a to-and-fro motion of the knob 4, and, when arranged, allow the flange 37 of the lever 36 to enter the notches 22, and disengage itself from the rib 39. The disks are then rotated all together, and turn the follower 26 by means of the lever 36 and thus withdraw the bolt. The plate 14, forming the connexion between the knob spindle and the disk-operating pin 17, is arranged to loosely engage the latter so as to allow the knob spindle slight longitudinal motion. The base of the knob is provided with balls 9 which are adapted to yieldingly engage a series of holes 10 in the plate 3<a>, mounted in the casing, when the knob is pushed in, and thus make it possible for the lock to be opened in the dark. By pressing in the knob to a greater or less extent; the volume of sound and the resistance to turning may be varied at will. A spring on the spindle may be employed to keep the knob in one or other one of these positions. As a substitute for the balls, ribs may he formed oa the base of the knob and on the plate 3<a>, or a pivoted catch 9<a>, Fig. 11, may be mounted in the knob to engage a series of notches 10<a> in the tubular part 3 of the casing when the knob is drawn forward so as to raise the catch by means of the spring 43. Instead of moving the knob to disengage the catch, the latter may be put into or out of action by hand. In the modification of the lock shown in Fig. 18, the bolt 31, shown as applied to a trunk &c. lock, is retained in its withdrawn position against the action of a spring 55 by means of a lever 56 mounted thereon to engage a slot in the fixed rib 58, and released therefrom by means of one of the hasp pieces when the latter enter the lock. When the bolt is shot, the lever 36, engaging notches in the disks, rotates these, but by reason of the flange 37 bearing against the inclined end 60<a> of the lever 60, Fig. 21, mounted on the casing, the lever 36 becomes disengaged from the disks, and the latter are dispersed so as to make the operation of the knob necessary before the lock can be re-opened. The lever 60, in the operation of withdrawing the bolt, is pushed out of the way by the flange 37, and allowed to drop back by its own weight. Another modification is described, in which the bolt is shot by a spring ; the disk-dispersing device described above is employed, and the bolt, when shot, is blocked against retraction by pressure on the bolt by means of a tooth 28 on the follower 26, as is shown in Fig. 2.
