FRANCIS M. IVILLIAUS, OF BROIVNSVILLE, PENNSYLVANIA, ASSIGNOR OF ONE-HALF TO R. R. BULGER AND \V. II. BULGER, OF SAME PLACE.

SAFE-BOLT-RETRACTING DEVICE.

SPECIFICATION forming part of Letters Patent No. 446,940, dated February 24, 1891.

Application filed April 15, 1890. Serial No. 348,075. (ModeL) enable those skilled inthe art to make and use the same, reference being had to the accompanying drawings, forming part of this description, in which drawings Figure l is an elevation of safe with door open, showing rear elevation of same with my improvement secured thereto. Fig. 2,is a sectional elevation of safe-door, showing position of bolt-locking device when locked. Fig.3 is an enlarged View of face of time-piece and pawl secured on door. Fig. at is a side elevation of same. Fig. 5 is an enlarged view of lever II.

My invention relates to a time-lock apparatus especially adapted to safes and vaults, the particular object of which is to furnish safes and vaults with a tiine-lockfastening constructed and placed wholly within the safe or vaultand having no connection or communication with the outside of the door or other part of the safe or vault,t-hus avoiding all danger from drilling and blasting, and at the same time furnishing a better, less complicated, and more reliable means of securing safes and vaults.

I construct my apparatus of iron, steel, brass, and other suitable material.

The particular improvements embodied in my invention will be hereinafter described and claimed.

In the apparatus embodying my invention I place two forty-eight-hour time-pieces A a, having one hand each B 1) against the interior side of safe or vault door at points near to and about equidistant from the top and sides of the door and secured to the door by the grooved fastenings or holders 0 c in such a manner that each time-piece may be adjusted to position by being turned to the right or left, as may be required. Between the two time-pieces A ct, I place the balance-wheel D. On the side of the balance-wheel D, I place cog-pin E. Between time-piece A and the balance-wheel D, I place the lever F, balanced on the pivot G and having arm or jog j to meet hand I) on time-piece A and shaped to fit round said time-piece. Between the timepiece ct and the balance-wheel D, I place the lever H, balanced on the pivot I and having an arm or jog J to meet hand B on time-piece (t and shaped to fit round said time-piece, as shown at Fig. 5, and having a notch K to fit cog-pin E on balance-wheel D. The notched end of lever II is made heavy in proportion, so that its weight will hold it securely in position on cog-pin E. On-the interior side of the safe or vault door, and below the parts above described, I place a counterpoise L, swung on a pivot m and having extension or lip 71. I connect the counterpoise L with balance-wheel D by rod f at a. On thelock side of the doorI place lock-bolts O O O,connected by upright P and secured to surface of the door by fastenings p p p p p, the center bolt having a head q, resting against extension or lip 7t of counterpoise L. I surround the center bolt between upright P and fastening p by spiral spring X, arranged to press outward and thus force bolts .0 O 0 into the keeper- .holes 71 72, h in the side of the safe or vault and lock the door.

On the time-pieces A a I place ratchet- Wheels R, and to fit ratchet-wheels R a keeper or pawl S, secured to surface of door by pivotpin T. This ratchet-and-pawl combination prevents premature turning of the time-pieces by reaction or other causes.

In operating my invention, the door being open, I raise the counterpoise Ii, place the balance-wheel D in position, with the cog-pin E fitted in the notch K in lever H, with the end of lever F under the end of lever II at point of contact 2', as shown at Fig. 2. I then turn time-pieces A a with respective hands- B b at distance from point of contact with lever F and H at t o to correspond to the number of hours it is desired to have the door remain closed. I then close the door. The

beveled ends of the bolts being brought in of time pieces being in motiomthe handsB l) on time pieces A a turn on with time until they come in contact with the arms or jogs jJ on balanced levers F andlI, or either of them, when the pressure of the hands B Z), or of either of them, tilts the respective levers F and II, raising the notched end of lever II. from the cog-pin E on balance-wheel D and setting the balance wheel and counterpoise free. A downward movement of the counterpoise L is then made by its own weight and operates by leverage of the lip n on the bolt-head Q and draws the connected lock-bolts O O from the keepers it h h in the side of the safe or vault and unlocks the door. The weight of the counterpoise holds the belts in reverse position until the apparatus is reset.

1 use two time-pieces, so that it either should fail or stop the other would alone do the required work, a by driving hand i") in direct contact with lever II, and A by driving hand 1) in contact with lever 1*, thereby raising lever F, and with it lever II, and unlocking door, as hereinbetore described.

What I claim, and desire to secure by Letters Patent, is-

1. In a time-safe-bolt'retraetingdevice, the combination of a solid door, two time-pieces suitably secured on the inner side thereof, a balance-wheel intermediate said time pieces, having a cog-pin on the side thereof, levers II and F, suitably pivoted between said tiniepieces near said balance-wheel, the outer ends thereof projecting toward said tin1epieces and terminating in a jog or inwardlyprojecting arm, the inner end of said lever ll having on its lower surface a notch adapted to tit: the cog-pin on the side of said balance wheel, a coi'interpoise pivoted upon an arm secured thereto, said arm having a lip, said counterpoise being secured to said balancewheel by a rod, and the locking-bolts, the innerend of the center one of which is surrounded by a spring and provided with a down wardly-projecting head, substantially as and for the purpose herein set forth.

2. In a time-safebolt-retracting device, the combination of a solid door, two time-pieces, a ratchet-wheel and pawl to prevent premature rotation of the same, a bLlfLTlCG-Wll0G1ll1- termediate said time-pieces and having a cogpin on the side thereof, levers ll and F, suitably pivoted between said time-picces near said balance'wheel, the outer ends of said le vers terminating in an inwardly-projecting arm adapted to strike or come in contact with the hands of said time'pieces, the inner end of said lever ll having on its lower surface a notch adapted to lit the cog-pin on the side of Slld balance-Wheel,and a eounterpoise pivoted upon an arm secured thereto, said arm having a lip, and said counterpoise being; secured to said balanee'wheel by a rod and sliding bolts, the inner end of the center one of which is surrounded by a spring and provided with a downwardly-projccting head, substantially as and for the purposes herein set forth.
