The Richards Absorption Dynamometer, designed by Mr. C. B. Richards, consists of a tank A B (Fig. 2) within which two paddle-wheels revolve in oil, thus producing a resistance and a tendency to rotate the whole tank, which is mounted on friction-rollers. This tendency to rotate is measuredby the lever-arm act-ing on a platformscale. By means of avalve the oil in thetank can be allowedto circulate withgreater or less free-dom ; by closing thevalve a pressure isl)rought to bear onthe oil in the tank, sothat the resistance tothe rotation of theinner wheels thus be-comes a drag on thedriving power; whenthe maximum resist-ance is obtained with-.
