GRASS-BURNER FDR RAILWAY-TRACKS.

Applieation filed January 18,

lie it known that i, ikLl lZlCli llsfreii that ii-li', a citizen oi the lfnited l'iil'es ol' I iea, residing at New Orleans. in the parish of Orleans and State ol' Louisiana have invealed certain new and usel'ul Improvemoms in (mass-Burners l'or l?ailwa lrac (s, ol ehieh the l'i llo .\'in;; is a speeitieation, rel erenee iHlliLI had therein to the aeeonipairvine' drawingv This invention relates to grassburners l'or railway tracks. and is designed as an iniproveoient in my Patent No. 451,215 granted to me April 2S, 1542)}.

The ohjeel ol' the invention is to provide novel and peculiar means for suppl' ."ing' gas to the grass burners or gas jets.

A l'urtlier ohjeet ol the invention is to provide novel and peculiar gas generating apparatus, and a special SyStU-lll lor germinating gas and for connecting the generator witl the gas jets or grass burners.

"A still further ohjeet of the invention is to provide special pipe connections between a gas generator and a source ol' steam, air and oil supply carried h a ear or engine.

in the a.eompanflngr drawings l'orniiire part ol this application: Figure .l is a side elevation of part of a ear truck showing the appli -ation ol the invention in section. Fig. 2 is a top plan view partly broken away. Fig. 3 is an end view partly broken away. Fig. 4 is a detail elevation of the jet-tank. Figs. 5 and 6 are detail elevations of the spray-nozzle.

The same reference numerals denote the same parts t-lu'ougliout the several views ol the drawings.

For purposes of eneniplilieation the invention is shown applied to a bed 1 el' a ilat railway car. A tank or other suitable inelosure 2 has a partition 3 inclined from its (7811- ter and divides the tank into a. gas reservoir 4 and an oil reservoir 5. The eenter ol' the partition 3 is provided with a hall cheekvalve 6, and the top of the tank has a similar valve 7. Said top having ordinary sal'el valve 8, and hand-hole 9.

Hot air is supplied to the reservoirs 4 and 5 from a supply pipe 10, having a braneh pipe 11 extending into the reservoir 4 and terminating in an air-jet 12 under the valve 7; and a branch pipe 13 extending through the partition 3 downwardly through a body Specification oi Letters Fatent.

of oil 14 in the reservoir 5 and terminating in a. spray-nozzle 13 at the bottom of the res- *rveir 5. \i'li.l'-?l'0l 3f the oil is supplied with lot air. r

The pipe 11 is provided with a suitable valve 15, and the pipe 13 has a similar valve to. An oil supply pipe 17 has a memoir pipe 18 lot earr ving oil into the reservoir 5, and is eontr lled by a valve 19. A steain sup-pl? pipe 20 is connected, by means of a valve 21 and. its eoupling", to a eoilpipe '22, immersed in the oil within the reservoir 5, for heating the oil eontained in. the reservoir 5. One end. of the coil 22 is connected to the. oil sup ply pipe 17 ll ahraneh pipe .23 having a suitable valve 24, and. the other end of the coil extends through the wall of the reservoir 5 and is coupled to a gas pipe 25, whieh eonlie reservoir '-l through its valve 7 with necls i a tanh 2h, having gas-jets 27 provided with regulating keys or val es 28.

it is ohvioiis that the valve it) is only opened when necessary to supoly the. reservoir 5 with oil, and that the valve. 24 ated to eharge the steam coil with a eertain amount of oil for mixing with the steam as it eonveyed to the as pipe 25. The eheel; valves 7 and. {S are operated respeetivelv by air from the air-jet 12, and by vapor or gas rising from the i)0(l 'y' of oil in reservoir 5, so that the pipe 25 is first supplied with gas, and then steam is inirodueeh into the pipe 25, wherel a mixture l gas and steam is fed to through the jets.

It will be seen that the operation. of feeding gas and steam together into the jet-tank is automatie, and that there is no oil fell to the jets, and therefore the rails are not oiled or greased by using the burner. it is obvious that the air and steaniniaybe sup lied from a locomotive or motor ear, and mat the oil may he supplied from a storage tank on such ear.

llaving thus described my invention What I claim as new and desireto secure by Lettors Patent is: f

1. In a grass burner for railway traeks, the eombination, with a tank having a valved top andadapted to he carried by a locomotive or 'ailway air, a valved partition separating said tank into gas and oil reservolrs, and a jet-tank, of a pi we connecting the top valve with the jet-tan a steam )ipe coiled within the oil reservoir and coupled to said is openother of which is connected to the said steam connecting pipe, air supply pipes to eachcombination, with a tank, a check valve in the top thereof, a partition separating the tank into gas and oil \IQSGIVOHS, a check valve in the Ipartition, a jet-tank, and a pipe connecting t e; said top valve With the jet tank, of an air supply pipe having branches, one of which discharges into thegas reservoir, and the other of which discharges into the oil reservoir, a steam pipe coiled in the oil reservoir and coupled to the said connectin pi e, an oil supply having branches one o? w 'ch opens into theoil reservoir and the pipe, and suitable valves in the various ranch pipes. p

3. In a grass burner for railway tracks, the

combination, of a gas generating tank having tank connected With'the said top valve, a

steam pipe extending through the oil reservoir and connected with the jet-tanl-:,-n1eans ,for supplying both reservoirs with air, and

suitable means for supplying one of the reservoirs and the steam pi e with oil.

In testimony 'whereof in presence of two witnesses.
