IMPROVEMENT IN COMBINATION PADLOCKS.

TO ALL WHOM IT MAY CONCERN: L v

Beit known that I, AUSTIN LEYDEN, of Atlanta, in the county of Fulton, and State of Georgia, have invented a new and improved CombinationLock; and I do hereby declare that the following is a full, clear, and exact description thereofgwhich will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification.

My invention consists in constructing a lock in such a manner that, in applying it to freight cars of railroads, and to similar purposes, the car may be locked for through freight, and the destination of the car be indicated by a letter shown on the lock, and so that a way-freight key for lthe'sanne lock will no t open it, as will be hereinafter described.

Figure 1 represents the key-hole side of the lock.

Figure 2 represents thc lock with the 'cap or key-hole side oil", showing the' parts of the lock which are operated by thetlirough"i`reigl1t key.

Figure 3 shows-the key-hole side Yturned over, and the parts ofthe look which are operated by the wayfreight key. v

Figure 4 shows the back side of the lock as when applied to acar destined to Chattanooga, for instance, 'the terminus of 'a railroad route.

Figure 5 is a cross-section ol' iig. 2 through the line :v rv, showing the through-freight key.

Figure 6 shows the disk-bolt; and v Figure 7v shows the way-freight key, a sidevand an end View.

Similar letters of reference indicate like parts.

v Thislock is really a double lock in one shell, cach part having its own key, and it is soa'rranged that neither key will operate the lock in the othcrs place. One key operates it for through freight, and the other for'way freight. i y

A represents the disk-bolt. 'This is turned upon its centre (t by the through-freight key seen in fig. 5. The letters A; C. W., as seen in dottcd lines in fig. 2, are upon its other side; and, whenthe disk is turned and locked bythe key, one of the letters comes opposite the hole through' the back of' the lock, as seen in iig. 4.

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

arc catches attached to the shell of the lock. The disk A cannot be turned by the key until `the end of the latch is lifted out of the catch. The through key has a. little projection for hearing upon thespring end of the latch and pressing it down, and thereby elevating thc-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 C', When the latch is at CH it is not locked by the through key; and the letter shown on the back is W., indicating way freight. When the lock is used lin this way, lit is locked by the other 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 iig. 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 through-freight lock, ns 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. IThe parts of the lock being so plainly shownv in the drawing, any further description is deemed unnecessary.

Having thus describedmy invention, what I claim as new, and desire to secure by'Letters Patent, is-

1. The disk-bolt A, constructed substantially as described, with vindicating letters upon one side, and thev latch B attaclled to the other side, and operating substantially as herein shown and described.

2. I claim the catch C C, attached to the shell of the lock, siibstantially as described,in combination with the disk-bolt A, for the purposes specified. v v

The above lspecilcation of my invention signed by me this day of November, 1866. v

AUSTIN LEYDEN.
