ACETYLENE-GAS GENERATOR.

SPECIFICATION forming-partcfI Letters Patent No. 654,968, dated July 31, 1900.- Applicatlon iled December 19,1899. i Serial No. 740,876. (No model.)

To all whom) it may concern.-

Be it known that LiHAnRY E. GIFFORD, a citizenof the United States, residing at Onset, in the county of Plymouth and State of Massachusetts, have invented` certain new and useful Improvements in` Gas-Producing Ap paratus; and I do hereby declare `that the following is a full,'clear,V and enactr description of the same, reference being Vhad to the annexed drawings, making fa part of this specification, and tothe letters ofu reference marked thereon.A f M f` The present invention has reference to that classof gasproducing y'apparatus in which a generator and gasometer are used anda gasproducingmedium consisting of calcium car.

bid or'other like material from which is manufactured what isf knwn'as acetylene gas, and the object vof the invention is, to improve such class of machines'a'in'the several details of construction wherebythe manufacture of gas is rendered `less dangerous and its production' materially simplified.

The inventionnconsists `in a gas generatori o r apparatus constructed substantially as shown in `the drawings and hereinafter der-'AA scribed and claimed. i V- c Figure l of `jthedrawings is a4 perspective view of a gas apparatus constructed in accordance with'lmy inventionj Fig. 2, a secl tionalelevation; Fig. 3,V a horizontal section taken on line 3 3 of Fig. 2; Fig. 4, a similar view taken on line l e of` Fig.42; Fig. 5, a de-V tail modied view-` of`the`plunger and the guide-rods with their connections. Fig. 6 is an enlarged 4detail 4vertical section of the valve whichcontrls the pipe between ithe, generator'and'gasometer.` c `4 In the accompanying drawings, A represents the generator of any preferred construction, which yis provided at its top and side with manholes a b, respectively, and closed by suitable screw-plugs c. This generator A contains a suitableioat B, having a reticulated receptacle d entirely within it to receive the calciumfcarbidor like material, which rests on the grating or reticulated bottom of said receptacle, so that it will be supported in normal position just above the water below. Connected to this float Br by karms e or other preferred means is a stem C', which en-V tends through the topl of the generator and .or changed as circumstancesrequiregwithout departing from the principle of the invention. The generator A is supplied with water through an overil'owftubef of any suitable form and construction and located at any distance from the top of the generator, and said tube may be of any suitable length desired and provided witha screw-cap g, said tube serving as an indicator in ascertaining the amount of Water required in supplying the generator. rIfhe tube facts as an indicator in ascertaining or'inlicating when the necessary amount of water is supplied to the generator. Inthe employment of the tube f only a certain height of water can enter the generator, as when uup to a level with the open end of the tube the water will ilow out `of the tube, thus indicating when the generator has its full supply. It is absolutely essential that the tube f be closed after the genpressure of the gasabove from forcing the water out of the tube, and for this purpose the screw-cap gis employed.

At the bottom lof the generator is a suitable discharge-pipeh of any preferred `form and. lconstructim, whereby the slaked carbid and water may be removed when desired.

The reticulated receptacle d of the -iioat B is supplied with the carbid through the manholes hereinbefore described when rechargiin'g, and the generator A may be attached to the other parts of the apparatus by any suitable and well-known means that will admit of the parts being easily separated for re To the upper or, open end of the gasometer and-*connected to erator is suppliedzwith waterto `prevent the IOO i when rising to its greatest limit.

the wall D is a suitable stop G, designed to limit` the rising of the dome above a certain point, the dome coming in contact therewith The stop G also serves as a guide to the guide-rod z', the end of the rod entering a hole vin the stop, or, if desired, the guide-rod may be formed rigid upon the stop and its lower end enter aV hole in the top of the dome F and into the hollow end of the plunger-rod C,"the lower end of the rod or the base ot the hollow portion thereof being closed to prevent the escape of Fig. 2 of" the drawings.

with Ithe top of the'generator and extending.

up centrally-into the gasorneter, as shown in j Aisay short central pipe secured to the top of the generator and surrounding the stem.

Between the central pipes A and H is .located a suitable gate-Valve j, to be closed whenever the generator iste be charged, and thusprevent the escape of` gas.

When the carbid is tof be renewed, the water is drawn oft 'from the generator, which operation will lowerthe iioat B, and alsothe stem C thereof is carried with it until the Y upper end is below the valve j, which will admit'offthe Valvebeing closed. The manhole ais `now opened yby removing the plug there.-

fromfand'sucjent water introduced into the i generator` tobring the oatnearly into place,

after which new carbid is supplied to the reticulated receptacle and the manhole closed and'the valveqopened `and any additional water needed being supplied through-the tube j at the side of the generator.

The pipe H,f`that connects the generator and gasometer, extends -into the latter to apoint near the top thereof, said pipe being of suicient size to carry the gas generated from the generator yto the gasometer in addition to guiding the plunger-rod in its vertical movement- .i 1

The -gasometer is provided with a suitable air-outlet, which is controlled by a valve '10,.

which outlet maybe at the top of the gasomthe ,top of the gasometer when Vthe machine` eter, asfshown in Fig. l of the drawings, or aj suitable pipe Am' may connect with 4an air#l outlet at the bottom of the gasometer and also with 'the blow-oi pipevmleadin g out of doors, asshown in Fig. -2 of the drawings, said pipe having a suitable -valve o and theblow-'ol pipe connecting withthe water-.trap .L This latter construction enables the gas rising .to

is first charged and the gasometerjull of air to forcethis airl down and out fromthe lower part of the gasomcter through the pipe m and pipe fn, thereby'carrying the mixture of Odensive airand gas out of doors. .The'gas after being generated passes to the consumer through a supply-pipe I, which extends into the gasometer and communicates therewith at or near the top thereof and extends down through the'bottonl of the gasometer, at which point it connects with a T-coupling and short pipe l, which latter `extends down into awa- "tertrap .T `of any. preferred construction. Throughthis trap the gas will escape should L- he gas lgenerate in a greater volume than the capacity of thegsometer andthat needed for consumption.

The supply-piped ,maycommun'icate with anysutbl@ System ofhouse--ppes found necessary to convey the gids tothe consumer as circumstances, mayreg'uire. A

When gas is generated, the dome F rises .and the plunger-rod C is carried withit, and as gas is used the dome falls, and when nearly down the end of theplunger-rod strikesjthe end of the stem C' of the float B, and .thus pushes the oat down, so that the waterwill come in contact with the carbid in the reticuL lated receptacle d. A s-the gas-is generated by the contact of the carbid with. the water the dome Vwill yat once rise and removethe pressure of the end of the plungerrod Q from the end of the stem Cf, thus admitting the float B to rise, carrying with itthecarbid in 'the retiulated receptacled abpve'the water until'gas is againconsumted, `when the opera-` tion will 'be again repeated. .i

It should be understood ,thattheendof the `stem C does l not vin Vany manner extend through the Valverand in .ordelto closesaid valve the upper end ofthejstem must b ebelow thevalve.

The construction of the valve is i?. .essential'to the successful voperationgoj' @capparatus, and, if desired, the usual rotaryplug valve maybe used, theendof the stemin such a ca seextending through .the port in the valve-plug.

It is evident that many changes and modi- Iications may be made in the. several parts comprisingthe apparatus without in any manner affecting .the general principle upon .Which the same operates or the essentialieatures which combine to renderI the apparatus s uc cessful in its operation.
