GOVERNOR FOR SUPPLYING GASEOUS FUEL.
SPECIFICATION forming part of Letters Patent No. 328,468, dated October 20, 1885.
Application filed January 3, 1885. Serial No. 151,937.
To all whom it may concern:
Be it known that I, ALPHEUS DARLING, of Petrolia, in the county of Butler and State of Pennsylvania, have invented a new and Improved Governor for Controlling the Supply of Gaseous Fuel, of which the following is a full, clear, and exact description.
My invention relates to governors for automatically controlling the supply of gaseous fuel to steam-boilers from the gas-tubes of oilwells or other source, the object being to improve governors of this class, so as to make them more sensitive to variations of boilerpressure, to more closely govern the fuelsupply, and also to increase their general efficiency and durability.
My invention consists in certain peculiarities of construction and combinations of parts of the governor and its connections to the gas well or source, and to the steam-boiler, all as hereinafter fully described and claimed.
Reference is to be had to the accompanying drawings,forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.
Figure 1 is a side elevation showing my improved governor connected with a steamboiler, to control its gaseous fuel supply, and with the gas-supply pipe. Fig. 2 is an enlarged longitudinal sectional elevation through the governor. Fig. 3 is an enlarged detail sectional view of a joint between two of the expansion drums or chambers which move the valve to cut off the fuel-supply, and Fig. 4 is a side face view of one of the expansion-drums, drawn to the scale of Fig. 2.
The letter A indicates the governor, which I make with a body portion or case, B, bored centrally to form the valve-chamber O, in which the double piston-valve D is fitted to slide.
I prefer to make the pistons 01 d of the valve separate from its stem (1 and hold the pistons to the stem by set-screws, permitting their ad- 5 justment on the stem with reference to the ports E F in case B, which open into the chamber (3, nipples e f being provided around the ports to receive pipe or cap connections.
At G is shown a port in case B, which port opens into the chamber 0, at a point about midway between the valve-pistons d d and ports E F, and has preferably a surrounding (ModeL) nipple, g, to which the gas-supply pipe H, leading from the gastube of the oilwell, is connected, to admit the gas to the valvechamber.-
A pipe, I, connects the port E with the gasconsuming furnace of the boiler J, and the port F may either be left open at its outer end or a cap may be screwed on its nipple f to close it, or a pipe may be connected at f to lead escaping gas to any suitable reservoir.
Above or beyond the valve-chamber O a larger chamber, K, is formed, to give room for one or more expansible drums or chambers, L, held to the cap-plate M, which is fastened by screws m or otherwise to the body of the governor.
The drums L consist each of a couple of thin strong sheet-metal plates or diaphagms, 11, connected at a little distance apart by a rim, so as to form water and steam tight chambers.
When a single drum, L, is used, its outer plate will open into a fixed screw neck or nipple, N, fitted to a tapped hole in the center of the cap M, and a lock-nut, n, screwed on the end of the neck N, holds the drum to place, and the inner plate of the drum will be imperforate and will bear at its center on the end of the valve-stem d but I prefer to emlarger degree of expansion or the same amount of expansion with less tension of the diaphragm, and in this case the adjacent plates, Z Z, of contiguous drums will be provided with screw-nipples l, which may be turned into threaded opposite ends of a screw-collar, O, with suitable packings, 0, interposed between the ends of the nipples and shoulders of the collar to prevent leakage from the drums, and the inner plate of the inner drum L, will be imperforate to bear on the valve-stem, as will be understood from Figs. 2 and 3.
I prefer to form crips, beads, or corrugations Z around or near the outer margins of the drum-plates Z, to give them easier and greater expansion.
To the projecting end of the nipple N is connected the pipe P, which is connected with the steam-space of the boiler J ,to admit steam under boiler-pressure to the interior of the drums L.
To the lower end of the body B of the govalong the chamber toward the drums L, and
a set-screw, U, threaded into the. end of the piece R,vmay be fadjustedto force the plate S inward (more or less) for regulating the tension of the spring T.
At V is a vent, allowing escape of any gas 7 which may leak past the pistons d of the valve, and is is a vent for the escape of any gas which may leak past the piston d into the chamher K.
The operation is as follows; The tension of spring T will be regulated by screw U, so as to hold the valve-stem d against the unexpanded drum or drums L when steam entering the drum or drums, from the boiler is at the desired pressure, and the valve-piston d then will give the desired opening. at theport E to pass the required amount of gas to the boiler-furnace, and the valve-piston d will close the port F. If, for any reason,the steampressure in the boiler J should suddenly increase, a like pressure will be exerted inthe drum or drums L, and will expand them so as to force the valve D back and close the port E (moreor less) by piston d,to cut off the fuel-supply until the steam-pressure lowers to the prescribed or normal limit, and as the valve moves back the piston d will uncover the port F (more or less) to allow any excess of gas to escape to the open air or to a connected reservoir; or the port F may be closed by a-cap or plug, as above stated, so that the pressure of the gas will back up in the pipe H; hence it is obvious that the port F is not essential to the working of the governor, but its use is preferred.
It will be seen that the gas-supply enters the governor through port G, between the opposite valve-pistons, which have like area, hence the valve will always be balanced, how
ever the pressure of the entering gas may vary, and the sensitiveness of the governor will be preserved,so it will closely control the supply of gaseous fuel to the boiler.
An important advantage resulting from the use of the closed metaldrum diaphragms L, over diaphragms consisting of a plate'of rub; ber, as in other gas-governors, is that the expanding drums L are not so liable to be corroded by the steam or water admitted to them,
so as to pass the steam or water to the valve.
mechanism and gassupply pipes to injure and choke them, and the drum-diaphragms more sensitively control the fuel-supply un-. der extreme variations in steam-pressure.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

A governor for controlling the supply of gaseous fuel, constructed with a double piston valve working in a case which has an inlet-port opening between the valve-pistons and an outlet-port adapted to be closed more or less by one of thepistons, an expansible diaphragm open to pressure and touching one end of the valve, and a spring pressing on the other end of the valve, substantially as here-- in set forth. 4
