Vintage Adlake Brass Padlock US OF O PAT 2040482 Heavy Duty No Key

Vintage Adlake Padlock
Brass Construction

This is a vintage heavy-duty padlock from the Adams & Westlake Co. (Adlake). The lock features a solid brass body with riveted construction and a thick shackle. The patent number 2040482 dates the design to 1936, placing it firmly in the pre-war industrial era. The front is stamped "U S OF O," possibly indicating a government or organizational use. This piece is a substantial example of vintage American-made hardware.

• Heavy-duty brass construction with visible rivets.
• Features a sliding dust cover over the keyhole marked with the "Adlake" logo.
• Stamped "U S OF O" and "PAT 2040482" on the front.
• No key is included with this lock.

Condition: Fair vintage condition. The lock displays a significant, uncleaned patina with numerous dings, scratches, and wear consistent with age and heavy use. A key piece of damage to note is that the shackle is broken/chipped on the locking side, which is clearly visible in the photographs. The sliding dust cover is present. Markings are legible.
