Abstract
26,787. Wilkinson, M. L. Nov. 16. Thermometers.-The instrument is more especially for clinical use. A bar D of German silver is fixed to the casing A, and at its left-hand end is bent over a bar E of hard rubber to which it is attached by a screw g. A bar D<1>, of the shape shown in Fig. 8, and again of German silver, is attached to the bar E at its right-hand end and to another rubber bar E<1> at its left-hand end, and these alternating bars are continued in the same way for several pairs. The difference in their expansions under a varying temperature being great, the last bar E which runs on rollers P, P, will have a cumulative movement. This movement is transferred by a lever system to a pencilcarrying lever tracing on-a-band drawn by clockwork from a spring barrel. To prevent excessive movements, a stop is placed in the path of one of the levers of the system which is capable of yielding when it strikes the stop by means of a spring, so that the mechanism is not injured or broken.
