PRESSURE-REGULATOR.

SPECIFICATION forming part Of Letters Patent NO. 131,961, dated July 8, 1890.

Application filed March 20, 1890. Serial No. 344,601. (No model.)

To all whom it may concern.-

Be it known that I, JACOB BARROW, a citizen of the United States of America, residing at \Vindfall, in the county of Tipton and State of Indiana, have invented certain new and useful Improvements in PreSSureRegulators and Gas-Separators; and I do hereby 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 letters or figures of reference marked thereon, which form a part of this specification.

My invention relates to certain new and useful improvements in gas-separators and pressure-regulators.

The object of the invention is to provide a receptacle consisting of a stationary outer cylinder, within which moves an inverted can or cylinder connected by means of bars and levers to a regulating or supply valve, so that the gas or fluid will be kept at a normal pressure at the point of supply or outlet; and it consists in providing the cylinders with inlet and outlet pipes, cocks for opening and closing the same, and with means for automatically turning the supply-cock as the inner cylinder raises and lowers, so as to keep a normal pressure within the same, the lever for operating the supply-valve having means connected therewith and with a movable can or receptacle, so that when it reaches a certain point the supply will be entirely cut off, as will be hereinafter fully set forth and particularly claimed.

In the accompanying drawings, forming part of this specification, Figure 1 is a perspective view, partly broken away to better illustrate the internal construction of my improved gas-separator and pressure-regulator. Fig.2 is a detail sectional view of the supplyvalve.

A refers to the supply-pipe through which the gas passes before entering the separator and regulator, and this pipe is provided with a valve a, which has secured to one side thereof an arm or bracket 1), the upper end of which carries a set-screw, which impinges on the valve-stem and is locked in place by a nut. The valve-stem, which lies horizontal, has

rigidly secured thereto a lever for turning said valve, as will be hereinafter referred to.

The supply-pipe Ahas connected thereto couplings c and d, from which extend short pipes having valves 0 and D, the pipe connecting with the valve 0 extending upwardly therefrom through the bottom of the chamber E to a suitable height therein,where said pipe 0 is bent downwardly, as shown. The pipe D connects with the valve D, and also passes through the bot-tom of the chamber E described, by a chain, which can be adjustably connected to the lever by means of a hook, as shown.

E refers to the inverted can, the bottom of which is open, and this can is placed within the chamber E, which contains a proper amount of liquid, the height of which is determined by the outlets 1, 2, 8, and 4, any

one of which may be left open, this construction being fully set forth in my prior patent for improvement in pressure-regulators, No.

397,063, dated January 29, 1889. The chamber E is maintained rigidly in position, while the can E is movable vertically within the same, and to the top of the inner chamber or can is secured a cross-bar g, the ends of which project beyond the outer chamber and have connected thereto links g, the lower ends of which are pivotally attached to a bifurcated or bent bar G, having parallel end members h h, between which are pivoted one end of the lever I and a curved'bar J. The curved bar J has its upper portion turned or bent and is provided with perforationsjj, while the lower member thereof extends down- 7 wardly and outwardly, the end being slotted for attachment thereto of a finger 70, adapted to engage with the pipe A or other permanently-fixed stop. The lever I, which is fulcrumed on the stem of the valve a, is pivoted between the members h h, and its end extends IOO upwardly and is pointed to enter the perforations jj in the flattened portion of the bar J, and when connected therewith the parts become substantially one lever. The opposite or outer end of the lever I carries a weight W. I

From the foregoing description of the parts the construction of my improved gas separator and regulator will be readily understood, and I do not wish to confine myself to the precise form of each element or part enumerated, but reserve the right to modify the construction within the scope of my invention.

In operation, to set the device as a separator and. regulator, the valve F is closed and the chambers filled with a liquid to the desired height, said liquid serving as a seal to prevent escape of gas. The gas containing a percentage of liquid passes through the regulating-valve a and valve to the chamber E, and any water or liquid mixed therewith will settle or condense in said chamber, while the lighter gas will pass downwardly through the pipe D and valve D into the pipe A, and from thence to the outlet. The pressure is regulated by the rise and fall of the cylinder E, as when the pressure becomes beyond normal the said chamber will be raised, and by its connection with the lever I will raise said lever to in part or wholly close the valve a. The position of the valve-stem of the valve a can be adjusted by securing the lever in one of the numerous perforations j in the pivoted bar J. If from any cause the inner can or chamber should fall below the normal height, as by a leak in the outer can, the bar-lever I would be lowered, and the curved bar J, abutting against the pipe A,

would release the said lever I, and by reason of the weight W at the opposite end'turn the valve to cut off the supply of gas. Now, from any reason should the pressure become excessively great and the can E elevated the plug f of the safety-valve would be moved off its seat and allow the gas to escape.

When it is desired to use the device hereinbefore described simply as a regulator, the valve F may be left open,-and when there is excessive pressure the gas will pass through the pipes C and D to elevate the inner receptacle and reduce said pressure. The regulating-valve is so constructed that it can be adjusted bya set-screw and lock-nu t, as shown in Fig. 2.

' Should the regulator and separator need repairs or should it be desired to cut it entirely off from the supply-pipe, the valves 0 and D may be closed and the valve F left open, and the gas will then pass through the supply-pipe in the usual manner.

It will be understood that the device will be used for all the general purposes of a pressure-regulator.

As asilnple illustration, it may be stated that it will be introduced in a pipe supplying a consumer.

contacts with a fixed part of the device, substantially as set forth.

2. The combination, in a pressure-regulator,

of the inner and outer chambers, horizontal bars G G, having a horizontal member, links connecting the inner chamber with said bars, a curved bar J, provided with a series of perforations, as described, pivoted to the projecting member and having a laterally-projecting portion, a regulating valve, and weighted lever for operating the same, the end of the latter engaging one of the perforations in the bar J, so that said lever and bar will move in unison, but be disengaged therefrom when the projecting portion of the bar contacts with a fixed portion of the device, substantially as set forth.

3. In apressure-regulator, the combination,

with the movable chamber anda supply-pipe communicating therewith, provided with a regulating-valve, valves 0, D, and F, of the curved bars connected to the movable chamber, and a weighted lever pivoted to the regulating-valve and to the outer ends of the said curved bars G, and the bar J, having a projecting end which engages with a fixed stop, and perforations in the opposite end with which the end of the weighted lever engages, as shown, whereby an automatic release of the lever is provided, substantially as set forth. 4:. In a pressure-regulator and gas-separator, the combination of a fixed outer chamber having inlet and outlet pipes, an open-ended chamber mounted therein and provided with a cross-bar g, bars G G, and links connecting the cross-bar therewith, a curved bar pivoted between said bars G G and provided with perforations and projecting end for engagement with a fixed stop, a regulating-valve a, valves 0 and I), connecting the supply-pipe with the inner chamber, and a valve F, located within the supply-pipe between said valves 0 and D, and a safety-valve connected to the movable chamber, the parts being organized substantially as set forth.

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

JACOB BARROWV.
