Original early 20th-century Universal Road Machinery Company Catalogue No. 10, devoted to Reliance Stone Crushing Machinery.

The catalog was issued by the Universal Road Machinery Co., with offices at 120 Liberty Street, New York City, factory at Kingston, New York, and additional offices shown in Boston and Rochester.

The front cover reads:

“Reliance Stone Crushing Machinery — Catalogue Number 10”

and this copy bears the dealer stamp of S. B. Plummer, New England Agent, Machinery Exchange, Oliver Building, Boston, Massachusetts.

The catalog describes and illustrates the company’s Reliance jaw crushers and related stone-crushing machinery used in road building, quarrying, aggregate production, and heavy civil engineering. Interior text discusses the construction and operation of the Reliance Steel Stone Crusher, including jaw plates, shafts, lubrication, materials, and the company’s “Reliance Spring” improvement.

This copy is especially interesting because it retains multiple original loose advertising sheets and dealer inserts, including material promoting the Reliance Spring and emphasizing the “cool running Reliance” crusher design.

A strong piece of early quarry, road-building, stone-crushing, mining, and civil engineering trade literature with additional regional interest from the Boston dealer stamp.
