Specification of Reissue Letters Patent. Reisgiled June 6,1911,

Original No. 955,660, datedulpril 19, 1910, Serial No. 536,143. Application for reissue filed January 17,

To all whom it may concern:

Be it known that l, JOHN LEVEY, n citizen of the United Sta-tes, residing in Chicago,

v i valves for use' under conditlons in which they are subjected to intense heat und tia-me, my invention relating particularly to valves employed in the gasconducting condiuts of t gus-producer apparatus'foreontrolling the passage' of the gas therethrough.

My object is to provide n siniple construction of vulve, suitable for the purpose-above referred to, which shall not be liable to iinpnirnient by the intense heat and the notion ot' the to which it is subjected in use, und which will present a. clear and linchstructed passage for the gases therethrough when in open condition.

{eter-ring.; to the accompanying draw'- ings-lfigure 1 shows by a view in elevation, in its greater port sectional, n gus-producer opparltus equipped with valves constructed in accordance. with my invention. Fig. 2 is un enlarged view in vertical sectional elevation of the upper one of the two valves controlling the flow ,of gus through the -producer; und Fig, a similar view lteken at. :i right-angle to that of Fig. 2.

The gos-producer apparatusl for use in connection, with which I have especially devised my improved valve, and in connection with which I have chosen to illustrate my invention, is ot' the lVilliurnson type involv ing, generally stated, e generzitor l provided with n, grate 5, afpair of clieclrenbriclr, vertically-disposed cerbureter and superheated chambers 6 und 7, respectively, communicating with each other nt their lower ends through an opening 8 in the'dividing wall 9 thereof, the chamber 7 containing n fineoutlet 1G for the products of combustion passing through the chain-ber 7 ,1 and n gasoutlet 1.1; and the chamber @containing an inlet l2 through' which the oil for mixture with thelxydrogen is sprayed therein; and n system of valve-controlledeondnits confleeting-the upper end of the chamber with 1 Serial No. 603,194.

the interior of the generator 4 above and below the grate 5 as follows: A conduit 13 opens et its upper end into the chamber 6 and at its lower end, controlled by a valve lll, into n conduit 15 lending into the upper end of the generatorlp Communicating with the lower end of the generator 4 below the grate 5 isn conduit 16, the outer end of which, controlled by a valve 17, opens into 4 an upright conduit 18 which is in communication :it all times with the' conduit 13', the valves 14 and 17 being connected together at their lever-extensions 19 und 20, respectively, by n' rigid rod 21 for operating them simultaneously, their posit-ions being such that when either one is open the other is closed and vice versa.

rlhe apparatus in so fer ns it is described, is of common and well-known construction, end as it operates in e well-known manner, description thereof in detail is unnecessary.

Itmay be stated, however, that after the steam introducedinto `thevgenerator 4. below the grate 5 at the point indicated at 22 has passed upwardly for n, few minutes through the incandescent cokebed and thence through the conduits 13 and 14 and chanibers 6 and 7, the lire becomes dendened, especially nt the bottoni, and it is necessary to reverse the How of steam therethrough, this being done by operating the'valves 14 and 17 to open vulve 17 and close vulve 14 end thereupon introducing steam into the generator above the grate 5 es et 23, the course of the steam and gas then being downward through the coke-bed and thence through conduits 16, 18 'and 13 and chambers 6 and 7.to the gas-outlet 11,. When the generator is fired, the valve 1li is subjected to tremendous heat, 21nd when the steam is introduced into the generator in the up and down runs, viz. when the steam sscends `and descends throughl the coke-bed both valves 14 and 17 are subjected tta-extreme heat and., furthermore, to the ection'of the gases, and it vis to nvoi-d impairmentto the valves in these conduits from the action of heet and gases that I havel especiafll devised my improved velve, 'of which till: following is a r description The valve 14 .is formed ot :i water-tight` vcasing 24 communicating with and securedk this hood being designed to be swung upon its trunnions into and out of a position in which it extends over the open'end of the nozzle 25. The casing 24 affords a receptacle for water which, in the construction illustrated, enters it at 29 and overflows therefrom through a pipe 30 communicating with the casing at 31, it being preferred that the flow of cold Water through the casing be continuous. The location of the upper end of the pipe 30, which is connected with the conduit 13 through a pipe 32 for equalizing the pressure on the.water, de-

termines the level of the water in the cas.

ing, which may be varied as desired, `it being necessary, however, that the water level be maintained at a point intermediate the top of the nozzle 25 and the lower marginal portion of the hood 28 when in the position represented in Fig. 2 for closing the valve.

' In other words, the hood must be submerged at i'ts lower end in the water when in the Yposition referred to ,and the u per end of the nozzle must be above the evel of the water, thereby forming a water-seal valve capable of vbeing opened by merely swinging the hood upon its journals to a position in which it is submerged in the water for uncovering the top of the nozzle, as indicated in dotted lines in Fig. 2.

The valve 17 is constructed as described ofvalve 14, this valve receiving its supply7 of Water for producing the seal, in the apparatus through the pipe 30, its overflow pipe being represented at 33.

As a convenient and economical way of luy-passing the gas from conduit 18 to conduit 13, when the apparatus is on a' downrun, I form on the outer surface ofthe casing 24 of the valve 14 a passage 34 which communicates at its' lower end with the .upper end of the conduit 18 and at its upper end opens into the 'conduit 13thus affording a Acontinuous passage between the con'- duits 18 and 13.

To prevent the nozzle 25A and conduit 13 from burning out, l prefer to line them, as

indicated at'35 and 36, with any suitable refractory materlal, such as tire-brick.

This casing is -ofA general sphericalV illustrated, from the valve 111 I It will be-manifest that by constructing a valve in accordance with my invention, the

joint instead ofbeingformed of contacting.

makingA of a satisfactory joint when thel valve is closed, and is not subject to impairment by continued use. Furthermore, by providing the water-seal joint, the nozzle is constantly submerged in water and the hood partially submerged at all times and completely submerged during the periodsmin which thevalve is open, which results vin cooling these exposed parts of the valve.V It will also be noted that when the 4valve is open, namely, when the hood is swung to the position represented in' dotted lines in Fig. 2, the passage from one conduit to the other is devoid of obstructions or impediments to the freepassage 'of the gas therethrough. i
