APPARATUS FOR CLOSING OR OPENING GAS PIPES OR CONNECTIONS.

SPECIFICATION forming part of' Letters Patent No. 555,795, dated March 3, 1896. Application filed August 18, 1894:. Serial No. 520,945. (No model.)

To all 'whom it 'may concern:

Be it known that I, CHRISTIAN IVEUSTE, a subject of the King of Prussia, Emperor of Germany, residing at Mlheim-on-the-Ruhr, in the Kingdom of Prussia, Germany, have invented new and useful Improvements in or Relating to Apparatus for Closing or Opening Gas Pipes or Connections, of' which the following' is a specification.

This invention relates to apparatus for closing and opening gas connections of all kinds by the transmission of liquid from two vessels communicating with one another into an inclosure in connection with the gas-pipes, which object is attained through an increase or decrease in the pressure in the pipes.

Figure 1 is a vertical section of a device embodying the invention. Fig. 2 is a vertical section showing a modification. Fig. 3 is a section of another modification, and Fig. a is a vertical section of still another modification.

The following description relates to various modifications in the application and use of this invention, which are described by way of example as being preferable for gas-lighting installations.

Fig. l of the accompanying drawings shows one device constructed according to this invention and so arranged that when the gaspressurc is interrupted or lowered, so as to extinguish the flames at the burner or gasstove, the pipe is also closed at once in consequence of the change of pressure by a liquid flowing into a reservoir c, whereby the supply of gas is entirely cut off, and thus on the renewal or restoration of the pressure all danger of an escape of gas is avoided. If this protection is to be extended to the entire house service, then the apparatus must be introduced into the pipe in front of the main gas-cock. Further, the apparatus can be used for special protection at any subordinate point in front of any single burner of group, gas-stove, dsc.

For example, assume that in a house the main gas-cock is turned oft and at the same time the closing of the taps of a gas-stove, burner, or burners is omitted. If such an apparatus as that above described has been specially provided at this particular point, no danger can ensue, because the pipes will be at once automatically sealed by the protecting apparatus, and thus when the gas is turned on again at the meter or main and the gas flows in all outlets of escape are guarded.

The object of the particular modification of the apparatus illustrated in Fig. 2 of the accompanying drawings is to open and close simultaneously all street lamps or houselighting services and the like which derive their supply from a branch from a central point in the general network. If the streetlamps are to be extinguished, then, for a moment or so, the pressure of gas at the central station is increased and then lowered to its normal amount. Thereupon the liquid flows into a pipe 7L and cuts off the gas supply. By a renewed pressure more fluid fiows into the pipe 7L and attains such aheight thatit reaches the top of the siphon which is connected therewith, whereby it is drawn off and theV pipe connection is again opened. The legs of the siphon are so proportioned that a certain quantity of fluid remains in the pipe to prevent an escape of The working of the apparatus is as follows: In the apparatus represented in Fig. l the gas flows in through a pipe a and passes through a funnel l) and through a sump or inverted siphon c to the outlet e and thence further to the point of consumption. The fluid is not always present in the sump c, wherefore a free passage is left open for thefiow of gas. If the receiver f be filled with fluid, the said fluid will stand at a lower level in the bell d, with which the receiver f is in communication, according to the pressure of gas, and this level is so arranged that with the lowest permissible working pressure it is coincident with the top of the funnel Z1. Then if the gas-pressure, from any cause or for any reason, be lowered so as to extinguish the flame at a burner or gas-stove which is protected by the apparatus the fluid in the reservoir f, seeking to rise to its own level as the counteractin g-pressure is removed, overflows into the sump c and closes the passage against the supply of gas. On the restoration or renewal of the initial pressure of gas at the inlet the fluid which has overiiowed into the sump c effectually stops the pipe. In this manner all danger of an escape of gas is prevented. If, now, the communication is to be reopened, the fluid in the sump is drawn oft through an IOO opening g provided for the purpose at the bottom. The replenishment of the fluid in the reservoir f, Figs. l to 4, can be effected either by hand or by an automatic arrangement.

In the before-described 1nodication(shown in Fig. 2) the gas enters bya pipe a and finds its way, as in Fig. 1, to the outlet-pipe e. Then it is desired to close the communication, the pressure at the central station is increased for a moment or so, whereby the surface-level of the iluid in the reservoir fis raised, so that a portion thereof overiiows into a pipe h and thence into the sump or siphontrap c, cutting off the gas supply. When the communication is to be restored, the pressure at the central station is again raised to such a degree that the fluid-level in the sump is raised to above the level of the top of a discharging-Siphon t' attached to the sump, which is thereby set in operation, and the fluid is thus discharged from the sump c and through passage restored to the gas supply. I

The gas-lamps Within the circuit protected by the apparatus, which would be provided with rekindling-jets, would be lighted up as soon as the gas supply was renewed. The legs of the siphon fi are so proportioned as to leave suflicient fluid in the bottom of the sump to keep the siphon sealed, in order that there may be no possibility of an escape of gas through the siphon.

Figs. 3 and 4 show the apparatus in operation, as in Fig. l. The different parts are only somewhat modied without departing from the spirit of the invention-that is, in Fig. 3 the sump cis located directly in the bottom of the bell d, and the exit-pipe e extends from near the bottom of the sump and out through the top of the bell CZ, and the same construction is shown in Fig. 4, excepting that the eXitpipe extends laterally at its upper portion and out through the side of the bell d.

l. A device for controlling a gas-supply, comprising a bell having a gas-inlet at its upper portion, a liquid-vessel surrounding the bell and having communication therewith at its lower portion, a seal adapted to receive liquid from said vessel, and a gas-exit pipe leading from the seal, substantially as specified.

2. A gas-supply regulator comprising a gasreceiving bell, a vessel surrounding the gasbell and adapted to contain a liquid into which dips the said bell, a sump substantially in the form of an inverted siphon providing a passage for gas and adapted to receive liquid from the liquid-containing vessel by overflow caused by a change oi' gas-pressure, and a siphon for automatically discharging liquid from the sump to the outer side thereof, substantially as speciiied.

3. A device for controlling a gas-supply, comprising a bell having a gas-inlet, a vessel rigidly connected to the bell and having a liquid seal into which dips the said bell, another seal adapted to receive liquid from the seal of the said vessel, said second seal co1nmunicating with the bell to receive the gas therefrom, and a gas-outlet leading from said second seal, substantially as described.

In test-imony whereof I have signed my name to this speciiication in the presence of two subscribing witnesses.
