Description

A superb J. T. Hayden patented pipe wrench, carrying the August 18, 1885 patent date and produced by Belden Machine Tools, featuring the distinctive “None‑Mar” jaw design that made this wrench one of the most innovative late‑19th‑century pipe‑holding tools.

Hayden’s patent introduced a clever non‑marring jaw system intended to grip pipe securely without leaving bite marks, a major advantage for plumbers and machinists working on finished or delicate surfaces. The form is unmistakably Hayden: the sculptural frame, the refined jaw profile, and the mechanical elegance that sets these apart from the more common toothed‑jaw pipe wrenches of the era.

This example is crisp, clean, and mechanically sound, with strong markings and excellent surfaces—exactly the kind of condition collectors hope for but rarely find. Hayden’s patented wrenches are scarce to begin with, and the Belden Machine Tools “None Mar” variant is one of the most desirable.

A top‑tier example of a truly inventive patented wrench.
