THEODQR HAHN, OF KGTZSGHENBRODA, GERMANY, ASSIGNOR To SIGISMUND MUHLENTHAL AND MAX LOEWENTHAL, OF BERLIN, GERMANY.
GAS-PRESSURE REGULATOR.
SPECIFICATION forming part of Letters Patent No. 661,867, dated November 13, 1900.
Application filed September 26, 1899. Serial No. 731,724. (No model.)
To (0Z6 whom it may concern:
Be it known that I, THEODOR HAHN, a sub-' ject of the King of Saxony, residing at Kotzschenln-oda, near Dresden, in the Kingdom of Saxony, German Empire, have invented certain new and useful Improvements in Gas- Pressure Regulators,(for Which I have applied for a patent in Germany, dated April 7, 1899,) of which the following is a specification.
The use of gas-engines and other apparatus with an intermittent gas-supply is accompanied by the disadvantage that in the gastnains supplying the engines or other apparatus variations of the gas-pressure are perceptible. Many attempts have been made to remove this disadvantage by using gas-governors; but still the end in view has only been imperfectly attained, and gas-burners, f0r example, which were situated near to the motor or other apparatus have still only given an it usteady and flickering light. The reason that. the apparatus hitherto used have not entirely removed these sudden pulsations of the gas in the mains is chiefly because these apparat us were only provided with a single gasotneter-hood, which without being assisted by a special pressure-regulator opened and closed the valve which controlled the entrance of the gas to the hood. In such apparatus the gasotneterhood must be considerably displaced-when, for example, gas is sucked in by a gas-engineand such hoods alone can not therefore entirely prevent sudden variations of pressure in the tnain.
According to the present in vention the gas before passing into the gasometenhood which controls a gassupply valve passes through a special pressnre-regulator'which is loaded in accordance with the friction of the gasotnet-erhood and in such a manner that the gas can pass into the gasometer-hood without perceptible impulses occurring in the regulator and gas-main. The channel connecting the gas-regulator and gasometer-hood is constructed sufficiently large as to allow the gas to pass Without offering any resistance.
In the accompanying drawings one form of the invention is represented.
Figure 1 shows a vertical section-0f the apparatus; and Fig. 2 is a detail sectional view on line on 00 of Fig. 1, the rollers being in elevation.
In the casing a a chamber 17 is provided,
closed at the top and containing the gasotneter-hood c of the gas-regulator, partially itnmersed in a liquid. This hood 0 is carried by a rod (1, the top of which passes through the top of the chamber b, but without packing, so that the air between the hood 0 and the top of the chamber can slowly escape upon the hood rising, and thus exercises a retarding influence. The rod (Z is jointed toa twoartned lever f, pivoted at c, which lever carries a valve g at the other end. This valve .g closes off the gas-main h more or less, and thereby regulates the pressure of the entering .gas. Anutnber of removable and exchangeable weights 1' can be applied to the rod d outside of the chatnber b, the purpose of which ,will be further described below. The gas entering from the main h passes into the gasometer-hood c, and in raising this latter the air above it is forced out of the apparatus, so that no shocks can occur. The position of the valve g, and consequently the pressure of the gas in the channel 7t, is dependent upon the position of the gasometerhood 0. Channel is constructed of sufficient dimensions to allow the gas to pass to the .opening of the valve Z leading to the gasotneter-hood 0 without sensible resistance. The valve l is supported by a relatively long two-- armed lever pivoted at m and so balanced bya weightn that the valve I can be displaced by a very slight force. A central rod 19 and rollers q of proportionately large diameter guide a gasometer-hood 0, so that it may rise and fall with as little friction as possible.
The manner of mounting the rollers q is rep resented in Fig. 2. At' the lower end of the rod 9 a pin 1' is provided which engages in a slot at the end of an arm on the top of the valve Z. This valve Z is consequently only raised when the gasometer-hood 0 has been raised above a certain height and lowered when the end of the rod 19 above the pin 0' bears on the arm 8.
The gas while entering the gasotneter-hood 0 will likewise pass into the gasometer-hood 0 when the valve l is open and from thence through the tube 25 to the engine or other apparatus. The gasometer-hood 0, which rapidly rises and fails, is again quickly filled with gaswithout resistance by reason of the pressure on the regulator-hood c, and, further, because no sensible resistance is offered to the gas by the channel 70, connecting the regulator-hood c and the gasometer-hood 0. The weightstlon the rod d are chosen according to the friction of the gasometer-hood 0. When the hood 0 has to overcome greater friction in rising and falling, the weight '1 is increased, the valve 9 consequently further opened, and the gas then passes at a greater pressure through the valve 1. The friction of the gasometer-hood 0 should, however, be kept as low as possible, so that the gas need only pass with relatively slight pressure into the apparatus. Inasmuch as the hood 0 is only able to move slowly and without shocks and a perfect balance of pressure exists between the two gasometer-hoods, it is evident that all shocks in the gas-main are entirely suppressed by means of this apparatus.
What I claim, and desire to secure by Let; ters Patent of the United States, is-
supply-pipe, said channel having an unobstructed communication with the hood 0, a valve for controlling the supply-pipe, operatively connected with the hood 0, a valve controlling the communication between the channel and the hood 0, and operatively connected with said hood, and a delivery-pipe leading from the hood 0 out through said channel, substantially as described.
4, A' pressure regulator, comprising two gasometer-hoods c 0, one of which 0 is surrounded at the top by an air-cushion, a channel below the hoods and into which opens the supply-pipe, said channel having an unobstructed communication with the hood 6, a
1. A gas-pressure equalizer tor use with intermittentgas-consumingdevices,comprising two gasometers connected one with the sup-v ply-pipe and the other with the deliveringpipe, a valve mounted upon a pivoted lever and adapted to close the communication between the two gasometers, connections from said valve to the bell of the gasolneter which is connected with the delivering-pipe, a counterweight on said lever whereby the valve is closed by the rise of the gasometer-bell, a valve between the other gasometer and the supplypipe, a pivoted lever carrying said valve, and connections from said lever to its gasometerbell adapted to close the valve when the bell rises, substantially as described.
2.

5. In a pressure-regulator, the combination with a chamber into which opens the supplypipe, two gasometer-hoods c 0 arranged above the chamber and with which chamber the hood 0 has an unobstructed communication,
