Patent for combination latch-locks, "in such manner as that the knob-latch, while performing its special function, will also serve as the lock upon any combination to which it may be adjusted, and the said latch can be operated from either the outside or inside of the door as a latch simply, or as a combination lock, which latter is further secured from the inside by the employment of a safety pin, rendering the bolt in its locked position perfectly secure, while by its partial withdrawal it prevents the possible change of the combination from the outside, and admits of the free use of the latch independent of such combination." (Lines 29-42) Includes instructions and illustrations.
