Abstract
9406. Phelps, B. May 4. Locks, key; latches.-A latch is formed with a frame which fits into a notch in the door stile, cut as shown in Fig. 5. The coverplate C on one side is adjustable to suit the thickness of the stile, the fore-end plate C<2> being made wider than the frame of the lock, as shown in Fig. 2, in order to allow such adjustment. The bolt I is pivoted to the lock frame C<3> at i, and is pinned at i<1> to a sliding plate H. The follower g operates this plate through a yoke plate H<1>, which has a T-headed pin h<1> passing through a slot h<2> in the plate H. The bolt is shot by wire springs 1, 2, coiled round a pin l and acting on the plate H. The boss G of the follower is hollow, and through it and bearings d, d<1> there passes a hollow spindle E, shown separately in Fig. 9. This spindle is formed with a finger piece F<1> at one end, and a knob F is fixed to it at the other as shown in Fig. 3. An arrangement is fitted on one side, and may be fitted on each side, for disconnecting the spindle from the follower and locking it to the frame. The latch can then only be operated on the other side by a key acting on an internal spindle L, which is connected to the follower G by a pin 8 passing freely through a slot 11 in the main spindle E. The arrangement for connecting the spindle E to the follower G consists of a second internal spindle M which has a pin 7 passing through a slot 12 in the spindle E so as to engage a notch 13 in the follower. By moving the spindle M longitudinally the pin 7 can be disengaged from the spindle E and engaged with a notch in the frame, disconnecting the follower and locking the spindle E. The spindle M is moved longitudinally by a cam K<1> acting on a stud 6 which is fixed to the spindle M and passes freely through a slot e in the spindle E. The cam is turned by a finger-ring K, and is concealed by a covering-ring 10. The striking-plate 30 is formed with a flange 31 to aid in forming the jamb and to prevent tampering. The latch may be used for either right or left hand doors.
