IMPROVEMENT IN SEAL-LOCKS..

Specification forming part of Letters Patent No. 165,915, dated July 27, 1875; application filed February 24, 1875.

To all whom it may concern: I

Be it known that 1, JOHN S. BROWN, of Indianapolis, Marion county, State of Indiana, have invented an Improvement in Oar-Locks and Seals, of which the following is a specification:

The object of my invention is to construct a lock with proper tumblers, with a key to operate them. The locking device and key-hole are to be-covered up with a hinged cover, and a seal is to be inserted in the front of the cover, so that when the cover is let down over the key-hole the seal shall project downward and over the bolt hole. in front of the body of the lock. The bolt is provided with a notch on one side, and passes through guides, and the holein the projecting part of the seal, into the front of the lock, forcing the tumblers back until the notchin the end of the bolt has passed them, Whenthey close up in the notch and hold it securely fastened, so that it cannot be opened until the seal is broken, so as to allow the cover to be raised and the key inserted, and press the tumblers back, when the notched bolt can be removed and the car is unlocked.

Figure 1 represents my improved lock and seal in its position on a car. Fig. 2 is a top view of my improved lock and seal. Fig. 3 is a side elevation of the same. Fig. at is a side elevation of the same, with the cover turned up, and the seal inserted in the front O represents the keyhole coverof of the lock are arranged tumblers, of any number, formed with hooks on the ends, so as to engage with the notch in the end of the bolt H. These tumblers are operated by a key, T, which is inserted in the top of the lock and under the cover 0, as shown in Fig. 4. E represents the seal, made of iron, or any other material, so that it is brittle, and has a form of a right angle. The part marked 0, Fig. 6, is inserted into the hole M of the cover 0,

Fig. 5, and the notches O O slide over the projections N N when inserted, and the cover 0 is then ready to close down, as in Fig. 3, after the key has been removed. When closed down, as in Figs. 2 and 3, that part of the seal marked G projects downward in front of the lock, until the hole P comes opposite the bolt-hole in the front of the lock; then the hasp or bar Kis placed between the lugs JJ, and bolt H is inserted into the holes in the lugs J J, over the bar K, and the notched end is forced through the hole P in the seal into the lock, thus closing up all comm unication with the key-hole of the lock until the JOHN S.
