Serial No. 414,307. To all whom it may concern: v Be it known that I, "lVILLIAM CULLEN Monnis, a citizen of the United States, residing at New York city, in the county of New York and State of N ew York, have invented certain new and useful Improvements in Liquid-Surface Drains for Gas-Holders, of which the following is a specification. This invention relates to a liquid-seal suriace-drain for gas holders and has for its object to provide a drain for receiving'and carrying oil the scum-that collects on the surface of the water which forms the liquid seal between the several sections of the gas holder. During the use of gas holders the surface oi the water employed to eiiect a liquid seal between the gas-holder. sections becoincs fouled by the collection of oil and other suband the result is that as'theinner shell or dome of the holder rises, because of the inlet of'gas beneath it, the fouled substances on the surface of the water contact with the walls of thesoveral sections and adhere theretojand cause damage to the wallsas well as produce an unsightly'appearance on the exterior. tion and one object therefore of this invention is to provide. surface drain that will collect and carry oillthe scum and impurities from the surface of the water and thereby ohviate the objectionable features heretofore referred to. Another object of the in. ention is to provide for the removal of the surface scum from that portion of the gasholdcr where it contacts-with the walls of the holder and to temporarily store the matter thus removed in a port1on of the holder where it cannot produce the objectionable results referred to. Another object of the invention is to provide suitable meanson the interior of the holder'ior separat'in one ortion of the liq-- ii'oln tiat portion which of the holder so that l uid sealing surface lies adjacent the walls the scum removed from that portion ofthe surface adjacent the may be tempo-- rarily stored in the removed portion. . Anotherobiect of the invention is to provide surface rains that \iill extend around the holder adjacent to butspaeed from the walls thereof, for collecting and drawing oil the scum from thc surface of the liquid seah- This objectionable feature necessitates a frequent painting of the gas, holder sections, which is an expensive operashows a ve'rtical sectional detai 55 ing mcdiuin and to also provide a receiving 1 space within the for receiving the scum collected by the drains. With theseand other objects in view, the invention is illustrated in the accompanying drawings, in which,- Figure 1, illustrates a oral sections of a gas holder,the crownor dome of the holder being removed to illustrate the structural frame work crnplo ed to sustainthe crown and also illustrates t e collector trough or drain sustained by the framework.

Fig. 6, shows a vertical sectionaliview through the trough and a side elevation-of the discharge pipe ,the section being taken on the line 66 of Fig.v 3, and Referring to the drawings by numerals, l, designates the supporting framework which may be constructed in any well-known or preferred manner. In the present instance this framework is provided with a plurality of vertical or upright posts, 2, which I propose in the present instance to utilize for sustaining the surface drain. The innermost section or gas-holder proper comprises the cylindrical vertical an, 3, and an arched doine or crown, 4, which inay nor 'mally be sustaincdby the structural frame work during the absence ol'gas. 'Ihe several cylindric sections, 5, surround the inner section so as to operate in the usual manner. The. particular construction of the holder is immaterial and the same may be varied widely from that shown as the present in vention does not reside therein. While in the present instance a water supply pipe, 6, is provided for the purpose of supplying water to eilcota liquid seal between the gas-holder sections, it is to be understood that any suitable form of water supplyinay be employed for this pu'rpose and it should also be understood. that rain water will also serve to provide a seal between the several sections. area bounded by the drains I plan view of the sev- Fig. 7,, illustrates a 'front elevation of the trough and discharge pipe. bottom. L The bracket arms which sustain the trough By reference to Figs. 3, 4 and 5 it will be seen that the upright osts, 2, of the framework carry metal brac et'arms, '7, the outer projecting ends, 8, of which incline down wardly and are curled over to form a hook, 9. The trough into which the scum is to be. drained has an outer circumferential wall, 10; an inner circumferential wall, 11, which is higher than the outer wall, and a flange, 12, which depends from and projects below the from. the framework maybe secured to the trough in any preferred manner but in the present instance the end, 8, of the arm, 7, extends over the lower outer wall and has its hook, 9, curled under the rolled or wired up per edge of said outer trough wall. '13, is bolted to the under side of the bracket, 7, and said arm extends downwardly and beneath the trough to form a bottom support I therefor, as clearly shown in Fig; 4. The position of the trough with res ect to the 'vertical wall, 3, of the inner hol' er section is such as to leave aspace, 14, between said trough and the vertical walls of the surserves to separate the surface scum. on therounding holder sections. In th present instance the trough extends continuously around the framework and in substantially the same horizontal plane as the surface or level of the liquid sealing medium while the depending flange, 12, on the trough extends vertically below and is submerged in saidliquid. This construction and arrangement of the trough and its pendent flange liquid in the space, 14, from the surface of the liquid in the space, 15, the liquid overflowing the lower outer wall, 10, into the trough. The trough is provided with one or more outlets through whicl1" the substances flowing into it may be conve ed off. This outlot is best illustrated in Figs. 3, 6 and 7 and consists of a depending tubular pocket, 16, to thelower end of which is connected a vertical ipe, 17. This pipe, 17, extends down ward y in the inner shell, then turns laterally in a horizontal direction, at 18, at the bottom of said'shell and extends beneath the telescoping surrpunding sections, 5,, then again extends vertically, at, 19, between the outermost and the next adjacent sections, as shown in Fig. 2. At the upper end the vertical portion, 19, ,ofthis outlet pipe is conpoint with respect the gas holder. By reference to Figs. 2and 6 it will be seen that the overflow pipes, 17, 18, and, 19, to. ' gether form a trap so the gas in the holder cannot escape through said overflow. I justify its remova An arm, '15, of the hol er and to do. this I eads to a pump in The nature of thepitoduct'that is drawn .pif from the surface of the sealing liquid in the sp ace,'11', is such thatit should not be emptied. into streams or sewers, and it is de slrable that it be disposed of in some other allow the same to accumulate and be stored untila suflicient qliantity has been stored to economically, In order to provide for the temporary stor-' age of this drawn-oil substance from the space, 14, I preferably run the t ie pump, 21, and to the latter pipe, 22, which returns to the gas-holder sections, as shown in Fig. 2. This latter pipe'then extends downwardly between said pipe, 20, to sections and has a horizontal stretch, 23, at the bottom of the holder which enters into the inner shell where it turns upwardly; at, Y 24, in, the space iuclosed by the trough, and the upper end, 25, of said pipe is curved over and downwardly so that the scum drawn off the sealing medium in the space,l4, is conveyed through pipe, 20, to the-puin and from the latter through pi e, 22, bac pinto the'inner shell and'depositer in the space, 15, whiclnis inclosed by "the trough and pendent liange, l2, thereon. By this means the central space, 15, in the inner shell may be utilized as a storage for the drawmoii scum until such time as it is desired to dispose of it, at which time the pum may be operated to draw the scum back t rough the curved end, 25, of the pies, 24, 23, and, 22, then through pipe, 26, t e valve, 27 being closed, and finally discharge it through pipe, During this 0 er'ation the valve 29, between pipes, 22,- an 28, will also beclosed. There may be times, for example, during rain. storms when it is desirable to convey the overflow from the holder off to a point without havin it pass into the central space, rovide a valve, :50, between pipe, 26, and the pump, 2]., which I, may close so as to shut the oven flow from the pump and allow it to pass through pipe, 26, directly into pi e, 28, in which event the valve, 29, will also e closed. A valve, 31, in the pipe, 26, when closed prevents the scumfrom passing direct 'to pipe, 28, when it'is desired to pump it into the holder. Having thus described my invention what I claim, and desire to secure by Letters Patent is,- 1. Thecombination with a gas-holder comprising a stationary shell section and a movable SllOll SfiC'b'lOIl having a 11 1nd seal be tween them, of means within t e movable shell-section and adjacent but independent of the walls thereof for receiving the sub stances from the surface of the sealing inedium, and drain connections communicating connect a with said means for conveying said substances from the latter. 2.
