The work was concerned with the design and construction of a high-temperature laboratory for use in investigation of the first and second stages of creep. The modification of four lever-arm units is described, with emphasis on the reduction of tare load, the minimizing of bending stresses on the specimen, and the improvement of the strain-measuring system. The design and construction of six dead-weight units is described. A unique loading system consisting of a barrel roller bearing, universal joint, and chain is presented. An accurate, automatic system for measuring and recording strain is described. The selection of proper furnaces and controlling equipment is described. Wiring diagrams, drawings and schematic diagrams are presented where pertinent. Author
