EDUARD JURGENS, OF QUEDLINBURG-ON-THE-HARZ, PRUSSIA, GERMANY, ASSIGNOR TO OT"O STEINLE, OF SAME PLACE.
TH ERMOMETER.
SPECIFICATION forming part of Letters Patent No. 395,279, dated December 25, 1888.
Application filed April 2, 1887. 1 Serial No. 283,535. (No model.) Patented in Germany November 23, 1886, No. 39,578; in France March 7, 1887, No. 182,035, and in Belgium March 9, 1887,110. 76,628.
To all whom it may concern:
Be it known that l, EDUARD JiiRGENs, of Quedlinburg-on-the-I-Iarz, in the Kingdom of Prussia and German Empire, have invented a new and useful Steel Thermometer for Liquids, of which the following is a specification, reference being had therein to the accompanyingdrawings, (110 patents being obtained by me anywhere for this invention save in Germany, No. 39,518, dated November 23, 1886; in Belgium, No. 7 (3,628, dated March 9, 1887, and in France, N 0. 182,035, dated March 7, 1887, these both latter-named patents being granted in the name of Steinle &I-Iartung, of Quedlinburg,) of which the following is a'speeification.
My invention relates to a steel thermometer for liquids.
Figure 1 shows a steel thermometer partially in a longitudinal section; Fig 2, a section through the dial-train of this latter. Figs. 3 to 6 are details of the steel thermometer on a large scale. Fig. 3 shows a hollowed spring with a steel reservoir, a, and the catch 0. Fig. -l shows a dial-train with the catch c in side elevation; Fig. 5, the same in plan. Fig. U represents a section through the cylindrical part of the hollowed spring with the pin 1:.
The steel thermometer for liquids consists of the steel reservoir a and the screw-shaped hollowed spring I), fastened thereon. The
lower extremity of this latter has a cylindrical form and incloses the pin 0, provided with a groove, 0. The above-mentioned pin 0 is inserted and driven into the hollowed spring in order to avoid said spring being driven out of the reservoir a by the liquid contained therein. The groove 0, arranged in the pin a, has the purpose to allow the liquid to communicate between the reservoir a and the spring I). The reservoir 0. and the hollowed spring b are filled with a liquid which, when heated, expands, and, thereby pressing against the insides of the hollowed spring and trying to vault it, causes the spring to turn. This rotation is communicated to the dial-train by means of the catch 6 on the upper end of the wire (Z, that is fastened on the spring. The catch c has a slit and can be displaced on the shaft g, provided with a pin.
\Vhat I claim, and desire to secure by Let ters Patent of the United States, is-
In steel thermometers for liquids, the pin 0, having a groove on its cylindrical surface, in combination with the twisted hollow tube 1), the lower end of which is hollow, cylindricalshaped, and with the steel reservoir a, substantially as described.
In witness whereof I have hereunto set my hand in presence or two witnesses.
EDUARD JURGENS.
