APPARATUS FOR REGULATING THE FLOW OF GAS OR FLUID BY STEAM-PRESSURE.

SPECIFICATION forming part of Letters Patent No. 416,061, dated November 26, 1889.

Application filed February 9, 1889.

To all whom it may concern.-

Be it known that I, GEORGE CoRYDoN JACKSON, a citizen of the United States, residing at Dushore, in the county of Sullivan and State of Pennsylvania, have invented certain new and useful Improvements in Apparatus for Regulating the Flow of Gas or Fluid by Steam-Pressure; and I do 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 appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

My invention relates to certain improvements in means for regulating the flow of gas or gasoline or other fluid to the burners of a furnace, boiler, or heater in which a gaseous or fluid fuel is employed; and it has for its object to so construct, arrange, and combine the parts that by simple and efficient means the flow of the fuel to the burners will be automatically regulated, so that a comparative substantially uniform temperature and pressure will be maintained, the volume of fuel, and consequently the intensity of the flame, varying with and being controlled by the pressure of steam in the boiler or heater, so that when a predetermined pressure or the pressure and temperature reduced, there being, however, a sufficient supply of fuel to maintain a flame even though the main supply of fuel be entirely out olf.

To the accomplishment of the above and such other objects as may hereinafter appear the means devised and employed for effecting them will now be described, reference being had to the accompanying drawings, forming a part hereof. v

Figure 1 is a side view of the mechanism with some parts in section and others broken away. Fig. 2 is a plan view of Fig. 1, showing a series of pipes and levers operated from a single steam-chamber. Fig. 3 is a side view showing a single lever used in connection with the other parts. Fig. 4 is a modified form showing the steam-chamber placed above the berial Nof299,240. (-No model.)

supply-pipe. Fig. 5 is another modification used for higlrpressure steam, parts being in section. Fig. 6 shows how a piston may be used instead of a diaphragm in the steamchamber. 1

In the drawings, the letter A designates a main supply-pipe for the passage of the fluid,

to shut oif the flow of fuel either wholly or partially as the lever is raised more or less.

In Figs. 1 and 30f the drawings I have shown the lever connected directly with the cook or valve II, the cock or valve being open when the lever is in its normal position. The movement of the lever in one direction is controlled by the pressure of steam againstthe bottom of the diaphragm E or its equivalent, the steam being admitted to the chamber D through the pipe I, which leads from the boiler of the furnace to which the flow of fuel is regulated. pressure at which the steam shall move the diaphragm or its equivalent to move the lever is fixed by the adjustment of the weight J 011 the extended arm of the lever G. If desired, a weight may be also applied to the opposite end of the lever.

It will be seen from the description so far given that when the temperature of the furnace reaches a higher point than is desirable and the pressure of steam is correspondingly raised the increased pressure of the steam in the chamber D will, through the diaphragm, stem, and lever, move the cook or valve in the main supply-pipe and cut off wholly or partially the flow of the fuel, and thus lower the fire, and consequently the temperature, and then as the pressure of the steam falls the weighted lever returns to its normal po- The predetermined sition and the flow of fuel to the burner increases. By such construction and operation the flow of fuel and the degree of temperature are controlled and regulated.

In order that-the flame of the burner may not be entirely extinguished when the supply through the main pipe is cut off by the stopcock or valve H, a by-pass is provided, so that there may pass a sufficient flow of fuel to keep up the flame. This by-pass is designated by the letter L, and is a branch pipe communicating with the main supply-pipe on each side of the cock or valve H in the main pipe, so that when the flow is cut off by the cock H a sufficient quantity of fuel to keep up the fire will fiow through. the by-pass, and thence through the main pipe to the burner. This by-pass is provided with a valve or cock M, so that the flow of the fuel through it may be regulated or entirely out off.

It will be observed that the arrangement and combination of parts described are such as to bring them into a narrow compass of space and to actuate the stopcock in the main supply-pipe through a weighted lever, which is intermediate of the stop-cock and the diaphragm, so that as a consequence the action on the stop-cock is sensitive and prompt, the parts are not liable to get out of order, and the flow of fuel may be entirely or partially cut off, as desired, through both the main pipe and also the by-pass. The arrangement also enables several main pipes to be operated in the same manner as a single main pipe from a single diaphragm or steam-chamber, as illustrated in the top plan view shown in Fig.2 of the drawings. In that figure is illustrated a series of four main pipes, although there may be more or less, each one constructed with a cock and by-pass, as hereinbefore described, and the series supported in the laterally-extending arms 0 of the bracket or standard 0, each main pipe of the series having a lever G, connecting with the of their length with a frame or cross-bar N,

which will be bolted, as illustrated, to the lever, which is pivotally connected, as previously described, to the stem F, so that when that lever is raised or lowered, as previously described, the whole series of levers will be raised or lowered, and the cocks or valves in the several pipes thus operated simultaneously, theweight on the main lever answering for all the other levers connected with it. It is obvious, however, without description or illustration that each lever might have its own individual weight. It will also be understood that while I have shown and claim the preferred form of connection of the several levers to the stem F, still I do not mean to restrict myself thereto, as the invention includes other modes or means for operating the series of levers from the one diaphragmchamber. It is also apparent that instead of having the diaphragm-chamber located below the main supply-pipe it may be above it, as shown in Fig. 4, and in that case the lever G may be connected to the cock or valve II by the two rods 0 and P. The operation will be the same as described under the preferred construction, and the lever will be intermediate of the cock to the main supply-pipe and the diaphragm to the chamber D, so as to transmit motion in the same way.

For furnaces or boilers where high-pressure steam is generated I prefer to employ a system of compound levers, as illustrated in Fig. 5, in which case the top or cover to the chamber D may be omitted, the diaphragm E itself constituting the top. In this form the stem F has connected to it the lever G, pivoted or fulcrunied to the standard P at one end, and at the other end connected by the rod or link Q, to the weighted lever G, which will be connected at Z) to the stopcock orv valve of the main supply-pipe A, supported by the bracket 0. The action of the parts described to regulate the flow of the fuel is the same as in the other forms hereinbefore described. The connection of the diaphragm is with the stop-cock in the main pipe, and the lever G, connected with the diaphragm and the cock or valve, is intermediate of said parts. The standard P may have an overhanging arm or projection Q', in which will work a set-screw S, which may be adjusted to regulate the throw of the lever G.

Instead of the diaphragm E, I may employ a piston T, (shown'in Fig. 6,) acted on by the steam in chamber D in the same manner as diaphragm E, and in that sense treated as the equivalent of the diaphragm.

If desired, cocks may be placed in the main pipes, so as to cut off any one pipe, while th others may remain in operation.

I do not confine myself to the bypass and cook or valve for the main pipe being formed in one piece, with a coupling between sections of the pipe; but I consider such construction as the preferred form, because it enables those parts to be quickly applied and renders the construction as a whole much simpler and stronger than otherwise.

This invention is particularly well adapted for heaters for warming buildings in which heaters gas or gasoline or other fluid fuel is used to generate heat; but I do not confine myself to such application of it, as it may be used wherever it will work to satisfaction; nor do I mean to confine myself to details of construction where equivalent constructions will accomplish the same results, although I do claim the details in addition to equivalent constructions and arrangements.

Instead of connecting the diaphragm-chamber D with the steam-space of a boiler, it is obvious that it may be connected with the water-space below the water-line, and thus it is evident that either steam or water may be used to move the diaphragm or piston, either of which constitutes a moving-head.

Having described my invention and set forth its merits, what I claim is 1. The combination, With the diaphragmchamber and its moving-stem actuated by a moving-head, of the fuel-supply pipe provided with a controlling cock or valve, a bypass connecting the main pipe on opposite sides of the cook or valve of said main pipe,

and a lever connected with the diaphragm-- stem and with the cock or valve, so as to turn with the cock or valve as apivot between the two points of connection between the bypass and main supply-pipe, substantially as and for the purposes set forth,

2. The combination, With a diaphragmchamber and its moving-stem actuated by a moving-head, of a bracket supported from said chamber, a fuel-supply pipe supported by said bracket and provided with a cock or valve, a lever intermediate of said cock and stem and connecting With both of them, and a valve-controlled by-pass communicating With the fuel-supply pipe on opposite sides of its cook or valve, substantially as and for the purposes set forth;

E. The" combination of the diaphragmchamber and its moving-stem actuated by a moving-head, a fuel-supply pipe, a coupling for sections of said pipe, formed with a cook or valve to control the flow of fuel through the supply-pipe and having a valve-controlled by-pass communicating with the interior of the coupling 011 opposite sides of its valve, and a lever connected with said stem and said main controlling-valve of the fuel-supply-pipe coupling, substantially as and for the purposes set forth.

4:. The combination, with a steam-chamber and its moving-stem actuated by a movinghead, of a series of fuel-supply pipes, each provided with aregulating cock or valve and a series of levers connecting the cocks of the several pipes with said moving-stem to actuate the cocks in the several pipes from the one diaphragm-chamber, substantially as and for the purposes set forth.

5. The combination, with a steam-chamber and its moving-stem actuated by a movinghead, of a series of fuel-supply pipes, each provided with a regulating cock or valve, and a lever connected with said stem and with the cooks to the several fuel-pipes to simultaneously actuate the several cocks from the same diaphragm-chamber, substantially as and for the purposes described.

In testimony whereof I affix my signature in presence of two Witnesses.

GEORGE CORYDON JAoKsoN.
