T. J. (Theron Josiaha) Palmateer

T. J. Palmateer, identified in library and catalog records as Theron Josiah Palmateer (1875–1955), wrote instructional books on machine-shop practice and lathe work. His best-known titles include Elementary Lathe Practice (1917) and Elementary Machine Shop Practice (published around 1918–1920), works that were intended for classroom use as well as individual study.

His writing is practical and direct, centered on teaching beginners the fundamentals of shop work through exercises and clearly organized instruction. The surviving records available online connect him most strongly with vocational and technical education, where his books appear to have been used as teaching texts for students learning machining skills.
