THERMO STEAM-PRESSURE GAGE.
SPECIFICATION forming' part of Letters Patent No. 277,446, dated. May 15, 1883.
Y Applicatio'n filed June 10, 1882. (No model.)
To all whom it may concern:
Be it known that I, PHILIPP BONTE, of Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Thermo Steam -Pressure Gages; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters oi' reference marked thereon, which form a part of this specification.
This invention relates to an apparatus which will indicate the pressure ol' steam in a boiler or steam apparatus of any kind by the temperature due to such pressure. Pressure and density ot' steam that is generated in free contact with water rises with `the temperature, and reciprocally its temperature rises with the pressure or density, and there is but one and a corresponding pressure and density for each temperature, and same pressure always exists in conjunction with same temperatures. Therefore an instrument that will accurately indicate the exact degree of heat ot' the'steam in a boiler will be the most reliable steam-press 'ure gage; and it is the object of this my invention to produce a gage that is based upon the above well-known facts.
For this purpose my invention consists in certain improvements in steam-pressure gages, as hereinafter described and claimed.
In the accompanying drawings, Figure l' `represents a vertical cross-section ot' my thermo steam-pressure gage; Fig. 2, a front view of the scale, and Fig. 3 a partial sectional Corresponding letters in the several iigures of the drawings designate like parts;
Adenotes the vertical shank ofthe glasstube, and B the horizontal shank of the same, hav ing bulb a that is filled with mercury. This tube is hermetically sealed after the atmospheric air has been exhausted therefrom in the same manner asin a thermometer after the bulb a has been filled with mercury. The ver tical shank A of the glass tube is secured by screws to the central ilute of a scale-plate, C, which is graduated at both sides, and has engraved on one side the numbers that indicate the degrees of heat and on the opposite side the numbers indicating the pressure of steam in pounds that correspond with such temperature. end an internally-screwthreaded Socket, b, into which is screwed an externally-screw` threaded pipe, D,which,at its rear end,is also internally screw-threaded, and into this pipe D is again connected an externally-screw threaded pipe, E,which,at its rear end, is also internally screw-threaded, to be hermetically closed by a screw-block, F. The horizontal shank B of the glass tube, with the bulb a, is inserted inuto the pipes D and E, anda washer, d, is passed over the glass tube and into the pipe E, and is backed by plaster-of-paris or cement, so as to confine the compartment in The scale-plate C has at its lower rearV such pipe E containing the bulb of the glass tube. 'Ihe otherwise empty space in this compartment around bulb a, I ill up with mercury or any other metal or metal chips or alloy, or any suitable material that is a good conductor of heat, so as to transport the exact temperature ofthe steam, water, or other heated nid that surrounds the pipe E to the mercury-cow taining bulb a.. The pipe D is screwed into a tapped hole in the boiler untilvthe socket b or an intermediate packing-ring will butt against the exterior surface of the boiler-head,and the nut gis screwed ou such pipe D against the interior surface of the boiler-h cad, so as to form a tight joint therewith. By this arrangement the bulb surrounding pipe E is extended a suflicient distance into the steam or waterspace of the boiler, and will be heated to the same temperature as the steam, which heat will be conducted to the bulb a and to the mercury contained therein. Such mercury will expand through tube B and thence into tube A, where its height will indicate on the scale the exact temperature and the corresponding pressure of the steam in pounds. The pipe E is screw-threaded its entire length for increasing the surface that is in contact with the surrounding steam or water, and thereby increasing its heat-cond uctin g capacity.
l am aware that it is not new to construct steam-pressure gages with a scale graduated IOC bulb within such casing With a heat-conducting material, and such I do not claim.
What I claim is- 1. Athermo steam-pressure gage consisting of a glass tube having vertical shank A, and horizontal shank B, having bulb a, that is lled with mercury, the end A of such tube being secured to a scale-plate, 0, and the end B and bulb a being inclosed in a pipe, D E, that is projected into the steam-space ot' the boiler, all substantiallyas and for the purpose described and shown.
2. In a thermo steam-pressure gage, or in thermometers in general, the glass tube having vertical shank A, horizontal shanh B,and 15 of two Witnesses.
