PAT 4644831 ROC PAT 27181. Subsequent discussion identified some manufacturing and distribution history for KLENK "SELECT-A-BIT": " ... although we have been unable to pin down the exact little shop in Taiwan who was cranking these out, I think it's accurate and reasonable to say they were made IN Taiwan FOR (take your pick) Klenk, Innovative Tools Line (which became part of Klenk) and then later Everhard (after their acquisition of Klenk).

Abstract: M1y invention consists in certain improvements in the known principle of producing motive power by the application of caloric to atmospheric air or other permanent gases or fluids susceptible of considerable expansion by increase of temperature, the mode of applying the caloric being such that after having caused the expansion or dilatation which produces the motive power the caloric is transferred to certain metallic substances, and again retransferred from these substances to the acting medium at certain intervals or at each successive stroke of the motive engine, the principle supply of caloric being thereby rendered independent of combustion or consumption of fuel. Accordingly, while in the steam-engine the caloric is constantly wasted by being passed into the condenser or by being carried off into the atmosphere, the caloric is in such engines employed over and over again, dispensing with the employment of combustibles, excepting for the purpose of restoring the heat lost by the expansion of the acting medium and that lost by radiation; also for the purpose of making good the small deficiency unavoidable in the transfer and retransfer of the caloric. Claim: The working cylinder and piston and the supply cylinder and piston of less piston-surface, the two pistons being connected with each other and working together, substantially as specified, in combination with the regenerator and heater, so that the air or other circulating medium shall pass from the supply - cylinder to the working - cylinder through the regenerator, substantially as specified, and give motion to the engine through the difference of area of the pistons, and this I claim whether the air or other circulating medium be made to pass on the return-stroke from the regenerator to the supply-cylinder or any other receiver or into the atmosphere.
