PHINEAS F. KING, OF ST. LOUIS, MISSOURI.
IMPROVEMENT IN TIME-LOCKS.
Specification forming part of Letters Patent No. 216,795, dated June 24, 1879; application filed February 10, 1879.
To all whom it may conaern Be it known that I, PHINEAS F. KING, of the city of St. Louis. in the State of Missouri, have invented a certain new and useful Improvement in Lockin g Devices for SafeDoors, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.
The object of thisinvention is to form an improved locking device controlled by a timelock placed on the inner face of around screwdoor, and having no connection with the outer side of the door. This locking device may be used by itself, or in association with any combination or key lock, for use during business hours.
The improvement consists in the peculiar arrangement and combination with each other, and with'their necessary adjuncts, of a horizontal ram and spring, pivoted latch, and pivoted dog and spring, as hereinafter fully described and claimed.
In the drawings, Figure 1 is an inside elevation of a safe-door closed and locked. Fig. 2 is a similar view of a door closed and unlocked. Fig. 3 is a detail, showing a modification.
A is a circular ring or jamb composing part of the front wall of the safe or vault, and forming the doorway into which the circular door B is screwed. This style of door is described in Letters Patent No. 7,802, reissued July 17, 1877, to which reference is made for detailed explanation.
O is a dog, which is pivoted at the jamb, as shown, and which is forced inward to the door by a spring, 0, so that its corner enters a recess, D, in the edge of the door when it is closed, and prevents it (the door) from being unscrewed, so that when the parts are in this position the door is effectually locked. (See Figs. 1 and 3.)
E is a ram, which, in Figs. 1 and 3, is shown as held back by a trip latch or catch, F, and which in Fig. 2 is shown as released from the catch. In the latter case it will be seen that it is projected outward by the spring 6, and forces back the dog 0 from its engagement upon a pin, h, In its preferred form the liftinglever H carries an adjustable segment, I, similar to that described (under letter Gr,) in Letters Patent No. 201,535, where its construction and connection are described.
J is the time-lock or clock inovemcnt, and J is a shaft turned by the clock-movement, and carrying hands or wipers K, which, at intervals of twenty-four hours, operate upon the segment I and liftaip the other end of the lifting-lever H. This movement lifts up the slotted end of the catch-lever G, and draws down the catch F from its engagement with the ram E, (permitting the spring 0 to force out the ram E and unlock the door, as before ex plained.)
It will be understood that the segment I is arranged upon the lever so that the catch will be disengaged from the ram at the proper time, and then the door cannot be again locked by the dog 0 until the ramis forced back and again engaged upon the catch F. This it is proposed to do by hand, and when the door is open and after this has been done the first time the door is closed and screwed into place the dog falls into the notch D, and the door is locked until the time-movement again disengages the catch F from the ram E.
It is not a matter of necessity that the seg went I should be made adjustable,for any suitable projection of the lever B for the hands K to act upon would answer the purpose, and the hands may be made adjustable on the time-shaft J, to cause the unlocking at the proper hour.
I claim as my inventionl. The combination of a horizontal ram, E, placed upon a round screw-door, and provided with spring 6, with, the dog 0, having spring 0, and pivoted upon the jumb A, as and for the through door or safe-body, in combination with purpose herein described. the horizontal rem E, pivoted dog (3, and piv- 2. The pivoted dog U, horizontal ram E, oted latch F G, as herein specified, and for the and pivoted latch F G, in combination with a purpose set forth.
time-lock on a round screw-door of a safe, as
and for the purpose set forth. PHINEAb KING 3. A time-lock attached to the inside of a Witnesses:
round screw-door of a safe, independent of SAML. KNIGHT,
combination or key lock, or spindle or shaft GEO. H. KNIGHT.
