GAS-REGULATOR.

SPECIFICATION forming part of Letters Patent No. 731,997, dated June 23, 1903.

Application led April 11, 1903. Serial No. 152,120. (No model.)

T0 all whom, t may concern,.-

Be it known that I, ALLAN M. FISHER, a citi- Zen of the United States of America, residing atEast Liverpool, in the county of Columbiana and State of Ohio, have invented certain new and useful Improvements in Gas-Regulators, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to certain new and useful improvements in gas-regulators, and relates more particularly to that class of regulators which are used to maintain a predetermined pressure in the outlet-pipe, the pressure of the supply to which is variable.

The object of this invention is to provide a cheap and eiiicient regulator which may be interposed within the pipe, whereby any predetermined pressure may be had in the outlet-pipe, the pressure of the supplyof which is variable.

In describing the invention in detail reference is had to the accompanying drawing, forming a part ot' this specification, and in which the view shows a vertical view, partly in section, of my improved device.

In the accompanying drawing the reference-numeral 1 indicates a suitable cock for controlling the supply of gas in the outletpipe 2, the supply-pipe (not shown) of which is connected with a port 3 of the valve. Interposed in the outlet-pipe 2 at a point adjacent to said cock 1 is a T 4, to which is secured the .vertical regulator supply-pipe 5. This supply-pipe has secured to its lower end adjacent the T4 a conical bracket 6, which supports the outer shell 7 ot' the water-sealed gasometer, the inner valve 8 of which is provided with a suitable guide-tube 9, the lower end of which is supported by brackets 10 10, and the upper end of which has provided therein apertures 11 11 for the purpose of permitting the gas which is supplied to the same through pipe 5 to escape to the upper end of the inner bell S. A vertical support 12, on the upper end of which a bracket 13 is secured, within which the horizontal rod 14 is fulcrumed, is provided. The inner bell 8 of the gasometer is provided at its upper end with a` split bracket 15, which straddles the said lever 14, and a pin running through said in the lever 14. The outer end of this le'ver 14 is provided with a series of notches 17 17, in which the support 18 of the weight 19 rests. The movement of said weight 19 determines the pressure at which the gas in the outletpipe is to be maintained. The opposite end of' this lever has provided therein a slot 20, through which the pin 21, provided in the valve-'stem 22, which encircles the end of said lever, is placed, said valve-stem 22 passing through a stung-box 23 in the cock 1 and connecting with the valve 24 within said cock.

While the gasometer is shown in its dry condition, it is obvious that a water seal may be placed in the same when the device is in operation.

The operation of the device is as follows: The gas passing through the port 3 into the cock 1 from thesupply-main will pass through pipe 2, and a portion of the same will pass through pipe 5 and apertures 11 into the upper end of the inner shell'of the gasometer, when the water within said shell will be forced downwardly, and the water contained in the annular space between said shell and the shell 7 will be forced upwardly. Should this pressure be sufficient to elevate the weight 19, the end of the lever 14 to which the valvestem 22 is secured will be forced downwardly, thereby forcing the valve 24 against its seat and discontinuing the supply of gas. The gas being drawn off from pipe 2 for the purpose of using the same will decrease the amount contained Within the inner shell of said gasometer until such time as the pressure of said gas is insuicient to support the weight 19, when the said weight will force the inner shell downwardly, thereby elevating stem 22, when the valve 24 will again be withdrawn from its seat and more gas be permitted to enter from the main. This operation being repeated will maintain the pressure within the outlet-pipe 2, said pressure being coincident with the adjustment ot' the weight 19 on the lever 14.

While I have herein shown and described bracket 15 passes through the slot 16, formed a practical form of my invention, yet` it will l Having fully described my invention, what said cock, the inner shell of said gasometer being provided at its upper outside end with a bracket which is 'slidably connected with a lever which is also slidably connected with the stem of the cock, the fulcrum of said lever being intermediate of the connection with said bracket and said stem, the free end f said lever being provided -with an adjustable weight whereby the pressure of gas necessary to actuate the inner shell of said gasometer may be varied, thereby regulating the pressure which will actuate said levrr and stem to operate the cock interposed between the supply and outlet pipes, substantially as described.

2. In a gas-regulator, the combination of a cock interposed between the supply and' outlet pipes, said outlet-pipe having a pipe connecting with a gasometer interposed Itherein at a point adjacent to said cock, said pipe ,connecting with the gasometer extending to the upper end of the guide provided on the inner side of the inner shell of said gasometer, suitable ports provided. in the upper end of said guides t0 permit the gas to pass into.

the upper end of the inner shell of said gasometer, a suitable conical support at the lower end of said pipe connecting with the gasometer. for supporting the outer shell of the gasometer, the upper end of the inner shell of said gasometer being provided witha bracket which is slidably connected with the lever which is also slidably connected with the stem of the valve interposed between the supply and outlet pipes, the fulcrum for said lever being located intermediate of said stem and bracket, and an adjustable Weight provided on the end of said lever opposite from that to which the stem is connected whereby the gas-pressure within said gasometer necessary to actuate said valVe-stem,thereby controlling the su pply of gas, may bevaried, substantially as described.

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

ALLAN M. FISHER.
