Kladnitskiy I. G. — Arched equimeasure

Up-to-date machinery, converting rotary motion into reciprocating one, has vital disadvantage: translational motion, both straight-run and return, is irregular. It is intolerable, for example, to the operation of a machine, effecting electrode oscillation at automatic-arc welding and facing. A description, geometric calculation and kinematic properties of the smooth curved line, named “arched equimeasure”, eliminating the above demerits, are given.
Key words: oscillation, cam-shaped and rocker mechanisms, automatic-arc welding, facing
