Hoyt's Engineers' Pocket Companion

A compact technical reference book designed for engineers, particularly those working with metals and mechanical systems. Published in multiple editions, it was issued by the Hoyt Metal Co. of Great Britain. The book contains a wealth of practical data, including tables, charts, and illustrations, covering topics such as material properties, engineering calculations, and bearing manufacturing. With around 230 pages, it features black-and-white photographs and detailed diagrams to aid engineers in fieldwork or design. Intended as a portable, quick-reference guide, it provides essential facts and figures for mechanical and structural engineering tasks, reflecting standards and practices of its time.  The four pages of graph paper at the back are clean and unused.
