ATENT FLUID-PRESSURE REGULATOR.
ESPECIPICATIQN forming part of Letters Patent No. 336,874, dated February 23, 18E6.
Application filed December 14, 1885. Serial No.185,6-20. (No model.) i
T0 (1% whom it may concern:
Be it known that I, STEPHEN STRUNZ, a citizen of the United States, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented new and useful Improvements in Fluid-Pressure Regulators, of which the following is a specification.
The purpose of my invent-ion is to provide a simple and efficient apparatus having automatic operation whereby the supply of natural gas to the furnace of a steam-boiler shall be regulated according to the variations of steam-pressure produced by variations in the consumption of steam.
It is my object, in other words,to produce an automatic supply of gas to the furnace,which shall be proportioned in volume to the requirements of the work done by the engine, thereby maintaining as nearly as possible an equable supply of steam under all circunn stances.
My invention consists in the several novel features of construction and combinations of parts hereinafter fully set forth, and definitely pointed out in the claims following this specification.
Referring to the accompanying drawings,
' Figure 1 is a view in elevation, partly in section, illustrating my invention. Fig. 2 is an elevation illustrating a slight change in construction.
In the said drawings the reference-numeral 1 designates a pipe leading from a naturalgas supply to a furnace of any suitable pattern for generating steam. In said pipe at any suitable point is placed a valve, 2, which may be of any desired form. XVithin a convenient distance from said pipe,at the point where the valve is located, is arranged a cylinder, 3, which may be suspended from a support, 4, attached to the pipe 1. This cylinder is supplied with live steam from the boiler by means of a pipe, 5, entering the cylinder at or near its bottom. \Vithin the said cylinder is placed a piston, 6, having a rod, 7 attached thereto and packed through the cylinder-head. The end of this rod is connected with a lever, 8, mounted upon the stem 2 of the valve 2. A convenient device for efi'ecting the connection of these parts is by a link, 9, which may be adjustable upon the lever 8. To this link is I connected in any suitable manner a rod, 10,
sustaining a weight, 11, the arrangement of the parts being such that the gravity of the weight tends to depress the lever Sand thereby open the valve 2, while'the upward movement of the piston 6 will raise the lever and close or partially close the valve, according to the degree of movement effected. Instead, however, of the construction described I propose, when desired, to employ that shown in Fig. 2, wherein the valve-stem 2 is provided with a lever very similar to the lever 8. (Shown in Fig. 1.) To the end of this lever is pivoted one end of an arm, 8, the other end being connected by a pivot-joint to the rod 10, which is merely aprolongation of the pistonrod 7. In this form of construction the weight 11 is attached to the rod 10 below the point of connection of the jointed lever-arm 8*.
The operation of these parts is evident. When steam is generated in the boiler, it flows through the pipe 5 and raises or tends to raise the piston 6 in the cylinder 3, thereby closing or tending to close the valve 2, the action of the steam in this respect being counteracted by the weight 11. Should the conlessened,an increasein pressure results, which at once raises the piston 6 and partly closes the valve 2, thereby cutting off a portion of the gas-supply to the furnace. On the other hand, should the steam consumption be increased either suddenly or gradually, a decrease in pressure results in the cylinder 3, whereupon the weight 11 draws down the lever 8 and opens the gas-port 2, thereby giving an increased supply of fuel to the furnace. It -will readily be seen that any increase or decrease in steam-pressure, from any cause whatever, will be at once compensated automatically by this apparatus.
adjustable in such manner that it shall act at different pressures, or, in other words, pre serve a greater or a less head of steam,as may be desired. I may effect this result in either of two ways-viz., by increasing or decreasing the weight 11, or by adjusting the cylinder and weight toward and from the gas-supply pipe 1. For the latter purpose the cylinder may be suspended from a link, 12, adjustable If desired, the apparatus may be rendered sumption of steam from the boiler be suddenly upon the support 4, the link 9 on the lever 8 being adjustable in like manner thereupon.
In order to provide for all possible requirements, the steam-supply pipe 5 is provided with a shut-off, 5, and the cylinder 3 has an escape, 13, provided with a cook, 13, by which the piston may be dropped at any moment by simply letting off the steam after closing the shut-0E 5.
\Vhat I claim is-- 1. In a steam-furnace, the combination ofa gas-supply pipe having a cutoil valve, a steam-boiler, a cylinder supplied with steam from said boiler, a piston moving in said cylinder. a lever mounted on the valve'stem and connected with the piston-rod beneath the cylinder, and a weight suspended from said piston-rod, substantially as described.
2. In a steam furnace, the combination, with a gas-supply pipe having a cut-otf valve and a lever mounted on the stem thereof, of a cylinder having a piston connected with said lever, a pipe connected with said cylinder and with the steam-space of the boiler, a weight attached to the lever and counteracting the action of the piston, and an escape-pipe communicating with the cylinder beneath its piston, substantially as described.
3. In a steam furnace, the combination, with a gas-supply pipe, of a cut-ofl' valve located therein, a lever mounted on the stem of said valve, a cylinder supplied with live steam from the boiler and havinga piston connected with the valve-lever, and a weight connected with and counteracting the piston, the cylinder and its connections being adjustable toward and from the gas-pipe, substantially as described.
4. In a steam furnace, the combination, with a gas-supply pipe, of a cut-off valve located therein. a vertical cylinder supplied with live steam from the boiler beneath its piston, ajointed lever having an arm rigidly connected with the stem of the supply-valve and the other pivoted to aprolongation of the piston-rod, and a weight attached to the latter and counteracting the steam pressure, substantially as described.
In testimony whereof I ailix my signature in presence of two witnesses.
