Offering for sale this matching lot of two (2) antique/vintage reversible heavy-duty industrial hand tools manufactured by the renowned Keystone Mfg. Co. of Buffalo, New York. These high-torque, manual ratcheting tools were heavily relied upon by late 19th to early 20th-century machinists, boilermakers, railroad workers, and shipbuilders for heavy-duty drilling, thread tapping, and structural assembly in incredibly tight spaces.
Item Specifics:
- Brand: Keystone Mfg. Co.
- Original/Reproduction: Antique Original
- Featured Refinements: Vintage Hand Drill / Reversible Boiler Ratchet / Structural Wrench
- Country/Region of Manufacture: United States (Buffalo, NY)
Tool 1: Reversible Feed-Screw Ratchet Drill (15 inches)
- Design: Long, heavy tubular steel body with a drop-forged head. Features a specialized knurled chuck adapter at the base.
- Functionality: The tapered, knurled tip features a dedicated pass-through Tommy-bar/pin hole. This was utilized to lock or release square-shank drill bits or taps. The octagonal housing shields the internal single-acting ratchet gear.
Tool 2: Female Square-Drive "Boiler" Ratchet Wrench (11 inches)
- Design: Shorter, high-leverage solid handle paired with a distinct, thick-walled bell-shaped socket housing.
- Functionality: Unlike modern socket ratchets that use a male anvil, this tool features a fixed female square drive opening. It was designed to slide directly over heavy industrial square lag bolts, nuts, pipe taps, or high-pressure steam valves.
Advanced Rear Direction Selectors:
- Both tools feature Keystone’s iconic rear-end knurled selector caps. Pulling or turning these knurled end knobs compresses the internal spring-loaded steel pawl mechanism, allowing the user to seamlessly toggle the tool between Forward, Reverse, or fully Locked configurations. The lower handle retains its original machined alignment slot and indexing pin securely.
Condition Report:
- Cosmetic: Gorgeous authentic time-earned patina with uniform surface oxidization/rust pitting. No cracks, welds, or structural damage to the forged steel housings.
- Mechanical: The internal ratcheting mechanisms are intact. Due to their age, they are currently tight/frozen from decades of storage and will require a deep penetrating oil soak (such as Kroil or WD-40) and flushing to restore smooth, click-through operation.
- Markings: Surfaces have general age wear. Faint remnants of original stamped brand impressions may be present but are currently obscured under the surface patina.
