INDICATOR-LOCK.

SPECIFICATION formingpart of Reissued Letters Patent No. 9,747, dated June '7, 1881.

Original N 0. 62,562, dated March 12,

To all whom t't may concern:

Be it known that I, AUSTIN LEYDEN, of Atlanta, in the county of Fulton and State of Georgia, have invented a provement in Indicator-Locks; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification.

My irvcntiou consists in constructing a lock in such manner that in applying it to freightcars oi railroads and to similar purposes the car may be locked for through-freight, and the destination of the car be indicated by aletter shown on the lock, and so that a way-freight key for the same lock will not open it, as will be hereinafter described.

Figurel represents the key-hole side of the lock. Fig. 2 represents the lock with the cap or key-hole side oil, showing the parts of the lock which are operated by the th rough-freight key. Fig. 3 shows the key-hole side turned over and the parts of the lock which are 0perated by the way-freight key. Fig. 4 shows the back side of the look, as when applied to a car destined to Chattanooga, for instance, the terminus of a railroad-route. Fig. 5 is a crosssection of Fig. 2 through the lineman, showing the throughfreight key. Fig. 6shows the diskbolt; and Fig. 7 shows the way-freight key-a side and an end view.

This lock is really a double lock in one shell, each part having its own key, and it is so arranged that neither key will operate the lock in the others place. One key operates it for through-freight and the other for way-freight.

A represents the disk-bolt. This is turned upon its center ct by the through-freight key. (Seen in Fig. 5.) The letters A O W, as seen in dotted lines in Fig. 2, are upon its other side, and when the disk is turned and locked by the key one of the letters comes opposite the hole through the back of the look, as seen in Fig. 4.

B is a latch attached to the disk. There is a small spiral spring under the inner end, as seen in Fig. 5.

(J C" are catches attached to the shell of the lock. The disk A cannot be turned by the key new and useful Im- 1867. Application for reissue tiled January '22, 188].

until the end of the latch is lifted out of the catch.

The through-key has a little projection for bearing upon the spring end of the latch and pressing it down, and thereby elevating the other end and lifting it out of the catch, as seen in Fig. 5. In this example of my invention the lock is locked when the latch is at the two catches marked (1'. \Vhcn the latch is at O" it is not locked by the throughkey, and the letter shown on the back is W, indicating wayfreight. WVhen the lock is used in this wayit is locked by the other or way key.

The parts which this key operates are attached to the under side of the cap or key-hole side of the lock, and seen in Fig. 3. There is nothing novel or peculiar to this portion, it being similar to the ordinary padlock. The key which operates it will not operate the throughfrcight look, as already stated, but the bolts of each lock take hold of the same shackle. The shackle does not have a hole at the end, as is usual with the shackles of padlocks, but there are notches or recesses on the sides of the shackle, in which the bolt rests when the lock is in use.

In pointing out some of the advantages of my lockit will be seen that the indicator-wheel, or disk with indicating-letters on it, is hung upon the key-pin a, and circnmscribcs the axis of the same, thus giving to the key-pin the double function of holding those parts as a central support, and also of centering the key. This secures a great advantage, in that the location of said pin inside the periphery of the indicator-wheel simplifies the construction of an indicatorlock, (which from its very nature is more or less complex,) and allows the case of the lock to be restricted to its smallest possible compass. By rigidly connecting the indicator-disk and the lockingboltA it willbe seen, also, that the lockingof the shackle or unlocked condition of the same by bolt A is always insured, according to the character or letter exposed through the case.

Having thus described my invention, what I claim as new is- 1. An indicator-lock consisting of the combination of a case having an opening in the of the indications on the anisnl, and an in dicatortrically upon the key-pin, (1 described.

the combination of ening in the some,

d within the ease, and ted to the indicatorsame for the exposure wheel, a locking me wheel hung coneen substan tially as shown an 2. In an indicator-lock the ease having the op indioatorwheel arrange the bolt rigidly connec constructed substantially eating-letters upon one the other side,

and operating substantially as herein shown and described.

4. The catches G G", attached to the shell 15 0f the lock, substantially as described, in combination with the disk-bolt A and latch B, for the purposes specified.
