IMPROVEMENT IN TIME-LOCKS.

Speozffcat'on forming part of .Letters Patent No. 105,291, dated July 12, 1870,

To all whom t may concern:

Beit known that I, CoRYDoN F. ATwooD, of Hancock, in the countyof Waushara and State of Wisconsin, have invented a new and Improved Safe-Lock; and l do hereby declare that the following is a full, clear, and exactv description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawing, forming part of this specification.

Figure 1 represents a front elevation of a safe provided with my improved lock. Fig. 2 is a vertical longitudinal section of the same, the plane of section being indicated by line .r w, Fig. 1. Fig. 3 is a vertical longitudinal section of the same, the plane of section being indicated by the line y y, Fig. 4. Fig. 4 is a ver-v tical transverse section of the same taken on the plane of the line e z, Fig. 2. Fig. 5 is a detail longitudinal section of the locking-bolt.

Similar letters of reference indicate corresponding parts. n

This invention has for its object to construct a safe-lock which will be absolutely safe against false keys, and which, in fact, cannot be opened by any key, being locked by clockwork that is concealed within the safe. No key-hole or knob will, therefore, enable burglars to apply their tools with a view of opening the lock.

This invention consists in an improved combination of parts wit-h a safe-lock under such an arrangement thatthe lock cannot be opened by any key.

The invention also consists in theconstruction of the setting and locking apparatus, and of other details, as hereinafter described.

A in the drawing represents a safe, vault, or other burglar-proof apparatus. B is the door of the same. On the inner face of the door are formed hooks or equivalent catches da, into which the bolts are to be locked. These catches are represented in Fig. 1, in which the door is shown open. -The bolts C G are pivoted tothe side of the safe, and are, it' desired, connected with each other by a rod, b, (shown by dotted lines in Fig. 1,) so that they will move simultaneously. The lock is connected with the rod d by means of a lever,

D, which is pivoted to the side of a plate, E,

that constitutes part of the inner lining of the safe. 'lhe lever D is, by means of a jointed rod, c, connected with a lever, F, which is also pivoted to the plate E, and which contains a springgcateh,d,that can be used to lock a pivoted hook, G, as shown in Figs. 3 and'.

When the lever F is locked to the hook G, it will serve to lock the lever D, which, in that position, holds the rod b down upon the hooks, locking vthe door. The lever D has a spring, e, which allows its outer part, even it locked by the hook G, to swing up, thereby can only be unlocked by appara-tus concealed within the safe.

The apparatus is made in form of a clock,

which, when wound up, can be set to swing the hook G, and thereby release the lever F at any desired time.

A spring, H, is connected with the lever F, to draw the same down, and with it one end of the lever D, thereby releasing both of lthe hooks a as soon as the hook G is swung clear' ofthe catch d.

The clock-work I, which is concealed within the safe, operates two hands, h and t', that move over the face of a dial, J, as in every ordinary clock. The dial is affixed to the inner face ot' the plate E, to be readily seen when the safe is opened.

Around the dial is placed a notched or toothed ring, L, which can be easily turned. Around the spindle is loosely fitted a third haud,j, which is made of spring metal, and carries a pin, l, that can readily be placed into one of the notches of the spring L. A projecting pin, m, on j, is in the way ofthe hourhand h. When the hour-hand strikes the pin m it will carry the hand j, and with it the ring L, around.

The upper end of the hook G is, by a link,

As the bolts are not connected with any outside apparatus,they

n, connected with a horizontal lever,` M, that extends inward through a slot ot' the plate E. The lever M is also locked into a notch of the ring L.

' When the hand lzy strikes the pin m and commences to turn the ring L, the latter will carry the lever M along until the same swings the hook Gr clear of the catch d. The safe is then opened. A spring, o, carries the lever M back to its original position, so that all parts Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The ring L, placed around the dial ot' a clock Within the safe, and connected With a hand, j, which is moved by the hour-hand h, substantially as herein shown and described.

2. The combination of the safe-bolts with the levers D F, hook G, and lever M, all arranged to operate as set forth.

3. The ring L, turned by the hand of a clock, and connected with the catch-hook G, to release the same, as specified.

The above specification ot' my invention signed by me this 17 th day of December, 1869.
