TEMPERATURE-REGULATOR.
SPECIFICATION forming part of Letters Patent No. 581,556, dated April 27, 1897.
Application filed March 19, 1894.
To a whom it may concern:
Be it known that I, EZRA S. HOYT, a citizenv of the United States, residing at Detroit, county of Wayne, State of Michigan, have invented a certain new and useful Improvement in Temperature Regulators; and I declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.
This invention relates to automatic heatregulators, and has for its object an improvement in that class of regulators which are employed for regulating the flow of a gaseous fuel employed for heating purposes. It is especially intended for use in places where it is desired to secure a very constant and regular heat, for keeping in a melted or fluid c011- dition any material liquefied by heat and which it may be desired to use in a liquid condition. It is also especially useful in connection with hot-water tanks that are connected with a source of supply and from which from time to time water is drawn away and replaced by cold water, which chills the water in the tank and which must be heated for use. I have found it very useful in connection with the casting mechanism of what are known as linotype or stereotype machines, where there is a constantly-repeated use of liquefied metal which must be kept at a temperature that does not greatly vary. In such cases if the -temperature of the metal is not kept high enough the metal will not flow. If kept too high, the metal is injured. I keep the temperature at the right degree of heat by regulating the supply of fuel by which the heat is produced.
In the drawings, Figure 1 shows my regulator in elevation, the reservoir part of it being in section. of the regulator. application.
This regulator consists of a cylindrical tubular valve-case 3, to one end of which is secured an extension 15, througlrwhich the outlet of the gas passing through the valve is laid. At the junction between the valve-case 3 and the extension 15 is an annular Valveseat 4, upon which is seated a cup-shaped Fig. 3 shows my device in Fig. 2 is a sectional elevation passes.

valve 5. The valve 5 is deep as compared with its diameter, and within its cavity is inserted the end of a regulating pressure-sprin g 7, one end of which bears against the inside of the closed end of the valve 5 and the other end of which is swiveled to a stem 8, that passes through a screw-threaded opening in the casing 15 and terminates at its outer end with a hand-bar The screw-threaded stem 8 passes through a packing-ring 18, within which is an ordinary packing-gasket. The closed end of the cup-shaped valve 5 rests against a diaphragm 6, that is interposed between the end of the valve-case 3 and an extension 16. The diaphragm 6 entirely closes the passage-way between the extension 16 and the valve-case 3.
At 1 is indicated the inlet passage-way, through which gas passes into the interior of the valve-case 3. The extension 16 consists of a reservoir 10, an expansion-chamber 11, and a pipe or passage-way connecting the two.
In the end of the expansion-chamber 11 is inserted a regulating-screw 12, and this screw 12 may be either in the walls of the chamber 11 or may be in an independent piece secured thereto, but separated therefrom by a dia phragm 17 ,which passes across the expansionchamberll. The reservoir 10 andthe passageway between the reservoir and the expansionchamber 11 and the expan sion-chamber 11 are filled with some expansible fluid, preferably mercury, and the pressure of the fluid contained in these chambers is regulated by the screw 12, pressing either directly against the mercury or against the diaphragm 17, the only necessity for the diaphragm being to prevent the mercury from escaping along the screwthreads of the screw 12, and this result can be attained either by the use of the diaphragm or by a very tightly-fittin g screw or by a suitable packing-gland, through which the screw The contact between the edges of the valve 5 and the annular seat 4, with which it is adapted to engage, is not so close as to entirely prevent the flow of gas through the pipes, but is so close as to check down the fiow of gas, so as to materially diminish the size of the flame when the valve is pushed against the annular valve-seat, and the quanvoir that its expansion causes the diaphragm 0 to yield and pushes thevalve 5 against the seat 4; when the desired temperature of the material in which the reservoir 10 is plunged has been reached. When the temperature falls below the desired point, the mercury immediately contracts, the pressure against the diaphragm is relaxed, the valve is forced away from its seat by the pressure of the spring '7, and there is a free passage for gas and the flame immediately increases. The screwthreaded stem 8,With its externally-projeoting part, furnishes a ready means for adjusting the tension of the spring '7 so as to regulate the act-ion of the parts from this side. In use I have found this regulator to be very sensitive, when used in connection with molten metal, which itwill keep at the desired temperature with great constancy, and also in connection with water-supply, in which the strength of the flame follows the temperature of the water with great regularity.
. The adjustments when once made to regulate the heat of any substance at any special temperature will remain in adj ustinent for a long period of time and need not be changed.
What I claim is- A regulator adapted to regulate the flow of gas to furnaces, comprising a valve forming part of the fuel-supply pipe, a reservoir of expansible material adjacent to the valvecasing, a flexible diaphragm separating the chamber within the casin g from the chamber within the reservoir, a cup-valve and an ann ular seat adapted to seat the rim of the valve, a rcgulatin g-sprin g and means for regulating the tension thereof from without the case, whereby the flow of the gas through the valve may be regulated to correspond with any one of several different temperatures, substantially as described.
In testimony whereof I sign this specification in the presence of two witnesses.
EZRA S. I-IOY".
