To whom it may concern.-

Be it known that we, CYRUS W. STEWART and CLARENCE A. KING, of Norwich, in the county of Ohenango, in the State of New York,

5 have invented new and usefullmprovements in Acetylene-Gas Generators, of which the following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

1o This invention relates to apparatus for generating, holding, and regulating the generation of acetylene gas.

Our object is to produce an improved generator and gasometer connected thereto which by its rise and fall automatically opens and closes the water-induction valve.

Our generator consists of a vessel which is divided into compartments by vertical partitions, and each compartment is subdivided by shelves or diaphragms, or otherwise, into chambers, separate or connected, the carbid being placed in these separate chambers, and when the water is let into a chamber of one compartment it will attack and exhaust the 2 5 carbid therein, overflow therefrom into other chambers successively to exhaust the carbid therein until all of the carbid in all of the chambers is slaked or used up, and then the water-pipe is automatically shifted to feed 0 Water to a second like vessel while the first is being emptied and recharged. The gasometer is mounted withawater seal in a suitable holder and provided with an arm which engages with a cross-bar upon the valve-stem of the induction-valve of the Water-pipe, so

that when the gasometer rises to a predetermined height a counterbalance will rock said valve to shut off the feed of the water and when it falls to a certain point the valve will be automatically opened and water fed from the gasometer-holder into the generating vessel. The oscillating feed-water pipe is automatically shifted by means of a float mechanism.

It is constructed as follows, reference being had to the accompanying drawings,in which- Figure l is a front elevation of the appara tus. Fig. 2 is a longitudinal vertical section of the generator. Fig. 3 is a transverse see- Fig. 4 is a like Fig. 5 is an ention on line macin Fig. 2. view on line y y in Fig. 2.

larged front elevation of the lower part of the apparatus, partly broken away to expose interiors.

A is a suitable base upon which suitable vertical side and end walls 2 are erected and provided with acentrallongitudinal partition 2, dividing the base into two divisions, each of which receives a separate generator. Each of these generators 3 4 is here shown in the form of a separate drawer for convenience in permitting one to be used while the other is being emptied or recharged or is exhausted. This comprises a box having a suitable bottom and suitable side walls and ends divided into compartments by vertical partitions 5, and these are in turn subdivided into chambers by boxes or horizontal shelves at, suitably supported so as to be removable, said chambers being suitablyconnected so that one will overflow into the next, these chambers being marked a, b, 0, (Z, c, and h. A suitable holder 7 is mounted upon or supported by said walls 2, and 6 is a water-pipe thereon, the upper end of which is suitably connected to the interior of 7 5 said holder, so as to take water therefrom, and is provided with a suitable shut-off valve 8, said pipe discharging into a cup 8, which is carried bya suitable support, wherebyit can be rocked thereon. Feed-pipes 9 10 are suitably connected to this cup, each being adapted to discharge into a receiver 11, from which the water flows through a suitably-trapped pipe 13 and piping 14 into a carbid-chamber, as a, into contact with the carbid therein, and 8 5 the gas thus generated is conducted by suitable piping into the gasometer 15, which is mounted" in the ordinary way in the holder with a water-seal joint. This gasometer is guided in its vertical movements by the ways 0 and rollers 16. An arm 17 on the gasometer engages with a lever 18 on the stem of the valve 8 in such manner that as said gasometer rises the counterbalance 18 will rotate the valve-stem to shut off the Water and as it 5 lowers will force this lever to open the valve and permit water to flow through either the pipe 9 or 10, whichever may then be in use. An opening 19 permits the water to flow from the chamber h into a cup 20, whence it passes through the pipe 21 into the cup 21, in which is a suitable float, and the stem 12 thereon engages with an arm-12 upon the pipe 10, (or 9, according to which generator is going out of use,) lifting it and lowering the other pipe, so as to shift the feed of water from one generator to the other, as from 4t to 3. An inverted box 23 is placed within the drawer and between its sides and ends and the vertical outer walls of the carbid-chambers with a water-seal joint, substantially as shown, and constitutes a primary gasometer, and as such has a limited rise up against the bottom of said holder, whereby part of the heat generated is absorbed by the water in the holder.

When it is desired to charge, empty, or recharge a generator, its gas-eduction pipe is suitably disconnected and the drawer drawn out, when by removing the box 23 the interior compartments are accessible.

Either drawer can be drawn out separately, and either of the boxes or shelves as can be removed separately for discharging or recharging.

In operation when the inlet or feed valve 8 is open the water will flow through one or the other of the pipes 9 or 10 into a receiver 11, whence it passes through the trapped pipe 13 and pipe 14 into chamber a. When this chamber is filled, it enters chamber 1), thence flows over the partition 5 into chamber a, and, filling that, enters and fills chamber (1, generating gas to the extent of the charge of carbid in each chamber, and so on until the several charges are all exhausted. The water from chamber 6 overflows through the conduit 19 into the cup 20, and when it is filled to a certain height the gas-pressure exerted backward from the gasometer will force water from said cup through the pipe 21 into the cup 21, gradually raising the float until its stem will engage with an arm 12, raise one of the pipes 9 or 10, shutting off the flow of water therefrom, and lowering the other to feed water into the other series of generating-ch'ambers.

Having described our invention, what we claim, and desire to secure by Letters Patent, 1s

1. A gas-generator, comprising a casing, a drawer removably inserted thereinto, and provided with transverse partitions dividing it into compartments, and separately-removable carbid-holdin g shelves, subdividing said compartments into vertically-connected generating-chambers, and having their sides separated from said partitions creating separate, but connected water-passages between them, a feed-pipe, a cup receiving water therefrom, and a discharge-pipe conducting it from said cup into one of said chambers.

2. A gas-generator comprising a casing, a drawer removably inserted thereinto, transverse vertical partitions of lesser height than the walls ofsaid drawer creating compartments, separately-removable carbid-holding shelves supported by the walls of said drawer, dividing said compartments into chambers, and having their sides separated from and creating water-passages between them and said partitions, and means to feed water into a lower chamber whence it can rise, fill the adjacent upper chamber and overflow into the next lower chamber through one of said water-passages, and so on through the series of chambers successively.

3. The combination with a holder, and generator therein, an arm upon said gasometer, and separate generators, of a feed-Water pipe taking water from said holder to feed it to said generators, oscillating branches leading to said generators respectively, a valve in said pipe, a lever upon its valve-stern with which said arm engages to open said valve by the fall of said gasometer, a counterbalance upon said lever, closing said valve as the gasometer rises, separate floats in said generators, each adapted to engage with a branch of said pipe, to raise it and shift the flow of water from one generator to the other.

In witness whereof we have hereunto set our hands this 30th day of July, 1898.

CYRUS W. STEWART.
