JAMES M. SWEENY, OF PITTSBURG, PENNSYLVANIA.
GAsREGULAToR.
SPECIFICATION forming part of Letters Patent No. 478,480, dated July 5, 1892.
Application tiled March 9, 1892. Serial No. 424,273. (No model.) Y
To all whom it may concern:
Be it known that I, JAMES M. SWEENY, a citizen of the United States, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania,have invented or discovered a -certain new and useful Improvement in Gas- Regulators, of which improvement the following is a specific-ation.
The invention described hereinrelates to certain improvements in regulators for controlling the l'low of gas to a single burner or one or more burners on achandelier or bracket; and in general terms the invention consists in the construction and combination, as hereinafter more fully described and claimed.
In the accompanying drawings, forming a part of this specification, Figure 1 is a sectional elevation of myimproved regulator; and Fig. 2 is a top plan View of the same, the nipple for the attachment of t-he gas-burner being removed.
The shell of the regulator consists of two concavo-convex disks 1 and 2, each provided with an outwardly-proj ectin g ilange 3. Across the lower disk 1 is stretched a flexible diaphragm 4, which is clamped to the flange 3 of the lower disk by a Washer 5, attached by a series of suitable screws to said flange. To the shell is attached a tube 6, which is threaded at its lower end for attachment to the gassupply pipe. Within the tube 6 is located the valve 7, which is provided with an upwardly-projecting stem 8, said stem passing through a sleeve 9, screwing into the tube 6, and having its lower end suitably shaped to form a seat for the valve 7. This stem 8 passes up through the diaphragm 4 and is connected thereto by suitable nuts 10, so that it may move with the diaphragm when actuated by variations of pressure of the gas. The upper portion of the stem 8 is made hollow and lateral inlet-ports 11 to permit the inf-low of gas are formed at the lower end of the hollow portion, as shown in Fig. 1. Between the nut l0 above the diaphragm and the upper disk 2 is interposed a spring 12 of a tension dependent upon the pressure of gas required in the burner, and the upper end of the valve-stem 8 is connected to the lower end of the nipple 13 by a flexible tube 14, so as to prevent any escape of gas into the upper portion of the regulator. O11 the upper end of the nipple 18 is attached a short section of tubing, suitably threaded at its upper end for the reception of the burner, or the burner may be attached directly to the upper end of the nipple 13. In order to prevent the rotation of the nipple 13 in screwing on the tube 15 or the burner, the opening through the disk 2 is made oblong and a correspondinglyshaped shoulder is formed on the nipple 13, as shown in Fig. 2. As the gas flows up through the tube 6 it will enter the portion of the regulator below the diaphragm, thence through the inlets 11 and hollow portion of the valve-stem, the flexible tube 14, and nipple 13 to the burner. In case of any sudden increase of pressure of the gas the diaphragm will be raised, the inlets 1l being of less capacity than the opening controlled by the valve 7 when fully open, thereby raising the diaphragm, and with it the valve 7, thus decreasing the amount of gas flowing into the lower portion of the regulator. As soon as the increased volume `of gas in the regulator below the diaphragm, due to increased pressure, has been consumed the diaphragm and the valve will either drop down or be forced down by the spring 12 and a new supply ot gas will enter.
I claim herein as my invention- In a gas-regulator, the combination of a shell, a flexible diaphragm interposed between the inlet and outlet of the shell, a valve controlling the flow of gas into the portion of the shell below the diaphragm, a stem, hollow for a portion of its length, connecting the valve with the diaphragm and provided with inlets, and a flexible tube connecting the stem with the outlet-nipple, substantially as set forth.
In testimony whereof I have hereunto set my hand.
JAMES M. SWEENY.
