The mechanic's text-book and engineer's practical guide; containing a concise treatise on the nature and application of mechanical forces; action of gravity; the elements of machinery; rules and tables for calculating the working effects of machinery; of the strength, resistance, and pressure of materials; with tables of the weight and cohesive strength of iron and other metals
An 1866 Boston reissue of Thomas Kelt's mechanic's text-book and engineer's practical guide, revised with John Frost, written for working mechanics and engineers who needed rules, tables, and geometry for machinery, materials, and strength calculations. The plates are small relief-cut line diagrams on cream stock: circles, arcs, chords, and intersecting construction lines labelled with serif capitals and italic lowercase letters, usable as geometric ornament, endpaper patterning, or technical texture.
