Different springs would be required for engines if of widely different power. Immediately over thespring will stand a light framework, carrying two independent types of recording gear, both ofwhich will, however, be actuated by the upper end of one and the same feeler or sliding verticalrod I, Fig. 1089, which will convey to them the vertical elastication of the middle point of the spring,on which point its foot rests. Under one type the feeler will govern the position of an integrating wheel J, Fig. 1089, workingon the face of a rotating disc. The rotation of the disc will be made proportionat
