Here is a rare brass Switch Lock (no key) from the "USY & T." (UNION STOCK YARDS & TRANSIT railroad), that name incised into the back side of the padlock. It is an ADLAKE brass lock, with the size, shape, and attached chain usually used for Switch Locks, and the Adlake name is written in raised cursive letters on the keyhole cover plate (the drop). Swinging the drop to the side reveals a number 362 stamped in the case, probably an ID number for this lock. Nothing else is on the front of the local. The back side has the railroad letters stamped in along with a patent number for the lock that was issued in 1936. There is no other lettering on the lock body or shackle.
This very short railroad line- total length 2.9 miles- was built back in 1866 not long after the famous Chicago Union Stock Yards were opened. It was built to connect the stock yards to other railroad lines entering Chicago, primarily for movement of freight, though for some years it did carry passengers as well on short trips. It was abandoned in 1957 as the stock yards died a natural death. Being so small, there were few locks and other memorabilia from the line to be later collected.
CONDITION: The heavy lock is 3-1/2" high and has an original chain. NO KEY. There is strong spring action on the drop. The lock has a dark brass patina and may have been cleaned long ago..
