UNITED STATES PATENT OEEIoE.
A. B. MULLETT, OF WASHINGTON, DISTRICT OF COLUMBIA.
IMPROVEMENT IN LOCKS.
Specification forming part of Letters Patent No. 59,628, dated November 13, 1866.
To all whom it may concern:
Be it known that I, A. B. MULLETT, of Washington, District of Columbia, have invented a new and useful Improvement in Locks; and I do hereby declare that the following is a full7 clear, and exact description of the construction and operation thereof, reference being had to the annexed drawings, making a part of this specication, in Which- Figures l and 6 are diii'erent views of Johnsons rotary lock-key. Figs. 2, 3, 7 and S are different views of my improvement thereof. Fig. 5 represents a portion of the door and a section of the key-hole. Fig. irepresents the plate through which the end of the key is i11- serted, and back of which it revolves.
The object ot' my invention is so to construct this plate and the end of the key that when the door is unlocked the key, instead ot' slipping from its place, hasa hold on this plate, by means of which the door may be drawn open by the key Without an additional knob.
The construction is obvious from a glance at the drawings, and need not be minntely described. The plate on the end of Johnsons key, in which the pins are fixed, is a cylinder, and hence there is nothing to hold the key in place When revolved.
My improvement consists in the addition of the plate, Fig. 4, with its peculiar key-hole, and in the key correspoliding thereto, so that when the lock is sprung the key remainsxed in place to draw open the door.
It is manifest that this may be done in various Ways by making the end of the key oval, or of any other regular or irregular form, eX- cept a cylinder; or it may be done by attaching lugs 011 the circumference ofthe cylinder.
What I claim as my improvement on said rotary lock, and desire to secure by Letters Patent, is-
The plate, Fig. 4, and its corresponding key, Figs. 2 and 8, made and combined substantially as herein-set forth.
A. B. MULLETT.
