Vintage Phelps Time Lock Excellent Condition Patent Pending 3 Keys Xtra TumblerUp for sale is a remarkably rare piece of early 20th-century security history: an authentic, antique Phelps Time Lock Corporation sequence deadbolt package.Unlike standard hardware of the era, this heavy cast iron rim lock was part of a high-security perimeter lease system. Retail stores utilized a master-key sequence where side and back doors had to be secured first to release or trap specific keys before the main master time-clock lock could be shut down for the night. Because these units were strictly leased and legally required to be returned to Phelps, very few complete sets survived in private hands.This specific unit features a prominent \"Patent Pending\" marking, dating its manufacture precisely between 1913 and 1921—prior to the permanent March 29, 1921 patent stamp seen on later production runs.What makes this lot an absolute premium tier for safe, lock, and industrial collectors is the incredible inclusion of factory spare parts that are typically impossible to source.PACKAGE INCLUDES:
• 1 Main Lock Body: Heavy cast iron surface-mount rim deadbolt stamped \"Phelps Time Lock\".
• 2 Matching Keys: Fully operational for the mounted lock mechanism.
• 1 Extra Original Tumbler: An interchangeable Phelps cylinder unit.
• 1 Additional Key: Cut perfectly to operate the loose spare tumbler.CONDITION:
The lock is in excellent vintage condition with a beautiful, untouched natural patina. The cast iron and brass elements show historic character without any destructive heavy scrubbing or modern modifications. The mechanics operate smoothly.
