Fig. 38. Scheme of Jacquet's sphygmograph. base, and thumb-screw D is turned into socket E. The paper, shown in cross section at F, runs between the roller G and two small wheels above it. Clock for moving paper is wound by means of large thumb-nut H, started and stopped by lever at /, and lever / gives a change of speed. Clockwork for time marker L, is wound by means of thumb- nut K, and gives fifths of a second. M is a clasp for hold- ing L up out of harm when not in use. Cam wheel P, turned by thumb-nut Q, varies the tension of the spring, by which button A'' is pressed on the artery. Movements of A^ are.
