Application filed November To all whom it may concern:

Be it known that 1, Kommn Jsoscm'm, a citizen ofv Germany, and resident of Mainz, Germany, have invented certain new and useful Improvements in Collecting Means for the Sealing Liquid ofDry G meters, of which the following isa speci cation.

My invention relates to gasometers of'the type shown for instance in United States 19 Patent No. 1,275,696 and which include a vertically movable sealing disc and are comm'onlyv referred to as dry asometers. In such gasometers, a sealing liquid is caused to trickle over the inner surface of the gas container and constitutes the medium where by the joint between the sealing disc and the container is sealed. The object of the res ent invention is to provide a novel an efficient means for collecting the sealing liquid and for maintaining an undisturbed flow of such liquid. The invention contemplates further the provision of a construction whereby the amount of the flowin liquid may be adjusted to supply the liqui $5 to the seal in the most des rable and eflicient quantity. Other objects will appear from the description hereinafter and the features of novelty will be pointed out in the claims. Y

In the accompanying drawing, which illustrates an example'of the invention without defining its limits,Fig. 1 isa fragmentary vertical section; Fi 2 is a similar horizontal section on the ine 2-2 of Fig. 1 and Fig. 3 is a detail view in vertical section illustrating another form of a. controlling element forming part of the invention.

As shown in the drawings, the invention comprises a container or gasholder 10 which a may be of the form shown in the above. mentioned patent and includes a vertically moving sealing disc 11 constructed in any well known way for reciprocation vertically along the inner surface of the container 10 in accordance with the quantity'of gas contained therein; a trough or its equivalent 12 extends peripherally of the sealing disc 11 in contiguous relatlon to the inner surface of the container 10 and receives the li uid 13 whereby the joint between said sea ing disc and the container 10 is sealed. The sealing li uid 13 is caused to trickle over the inner sur ace of the container 10 from recept-acles usually located at the 11 per por- \sealing' liquid trickles downwardly thereat its ower end extends into the tank 15 so 14, 1924. serial no. 749,8d3.

tion of the tank and is temporari y held in the trough 12 m sufiicient quantity to efi'ect a gas-tight seal between the sealing dim 11 and the container 10; after having pen formed its functions in the trough 12, the

from mto the annular channel 14 located upon the bottom of the container 10,v as shown -m Fig. 1. As so far described the. construction may be of any well known type and may include such features as are commonly found in gasometers of the character under discussion. The present arrangement includes a collecting tank comprising a shell 15 of metal or other suitable material sunk into the ground at a point outside of the container 1( );for instance as indicated in Fig. 1.. A. dlp pi e 16 closed at its upper end and open as to terminate at a distance from its bottom and to pro ect for a considerable distance into the seating liquid 13 which is collected in said tank, as will appear more fully her-einafter. The dip pipe 16 which is of relatively large diameter is preferably located near one end of the tank 15, the latter, as shown in Fig. 2, being of generally rectangular form; a horizontal connecting pipe 17 extends fromthe upper portion of the dip pipe 16 to the contains 10 near the bottom thereof and serves to connect the latter with the dip pipe as shown in Fig. 1. In the preferred arrangement, the connecting pipe 17 is of such length and is yieldingly attached to both the container 10 and the dip pipe 16 in such a manner that a foundation .settlement will not interfere with the safeand proper operation of the collecting tank. This pipe 17 serves to conductthe sealing liquid 13 which is collected in the annular channel 14 to the dip pipe 16 and thence to the tank 15. The sealing liquid generally be provided in the connecting pipe 17 for completely disconnecting the dip pipe16 from the container 10.

At the end which is opposite to that end at which the dip pipe 16 is located, the tank 15 is provided w1th a pipe 21 which serves to connect said tank with a suitable pump whereb the sealing liquid is conveyed from the ta 15 to the collecting means or tanks located generally in the upper end of the container 10; as the latter are well known in the art and form no part of the present invention, it has not been deemed necessary to illustrate the same. In order that the pump may be automatically controlled in such a manner as to operate only when the sealing liquid collected in the tank 15 reaches a predetermined level, a float 22 is provided which rises and falls with the changes in the level of the liquid 13 in the tank. The float 22 is connected by means of a rod 23 with a lever 24 which in turn operates a connection 25, whereby the starting and stop ing of the aforesaid pump is controlled. s such arrangements are well known, it is not considered necessary to either illustrate or describe the same furt er.

In order to prevent foreign objects or matter which might float on top of the sealing liquid from interfering with the float 22 and to prevent water which might pass in small amounts from the dip pipe 16 to the tank 15 and form ice during freezing weather from similarly interfering with said float 22, the partition 26 is rovided in the tank 15. This artition divides the tank 15 into two in ependent chambers a and b which communicate with each other by way of the bottom of said partition, the latter being spaced from the bottom of the collecting tank 15 as shown; the liquid 13 is thus forced to pass from the chamber a of the tank 15 .to the chamber 5 beneath the partition 26. Any foreign matter, water or the like, which may float upon the surface of the liquid in the main portion of the tank will therefore simply rise and fall with changes in the level of said liquid and accordingly will not reach the chamber 1); any

I ice which may form as a result of the presence of such water will thus be maintained out of contact with the float 22. A second partition 27 may be provided upon the bottom of the tank 15 at a distance from the partition 26 as shown in Fig. 1. This second partition extends far enough above the lower end of the dip pipe 16 to provide an adequate liquid seal therefor at all times in the chamber a so that even if the liquid level in the chamber 6 of the tank descends to said lower end of the ipe, the gas in the the tank 15, the float 22.will rise and fall accordingly and thereby will start and stop the pump to automatically transfer the liquid 13 from the tank 15 to the collectin tanks or their equivalent at the u per on of the receptacle 10. The flow of t e liquid from the channel 14 through the pipe 17 may be adjusted by settin the weir 18 in different positions, as will fie apparent from an inspection of'Fig. 1 of the drawings. If it is desired to completely disconnect the receptacle 10 from the tank 15, the gate valve 20 or its equivalent may be operated accordingly. Because of the fact that the gas pressure in the receptacle 10 is effective in the dip pipe 16, the level of the liquid is lower than the level of said liquid in the tank 15 as indicated, for instance, in Fig. 1. At the point at which the level of the liquid in the dip pipe 16 is located, a drainconnection 28 is provided for drawing off such water as may float upon the top of the seal ingliquid in said dip pipe 16; the latter is made of large diameter, so that the withdrawal of this water is facilitated.

In place of the two independent elements 18 and 20 for controlling the flow of sealing liquid and the connection between the container 10 and the di pipe 16, aisingle element constructed and arran ed to erform the functions of said two 1ndepen ent elements may be substituted. As shown in Fig. 3 said single element may consist of a gate valve 20, the valve member 20" of which, contrary to the normal operation thereof, is arranged to be 0 e'ratively. shifted from a lowermost open position to an uppermost closed position. By setting the member 20 to intermediate positions, for instance, as indicated in Fig. 3, the upper edge thereof serves as a weir which may be adjusted to any desired level to control the flow of the sealing liquid to the tank 15 the valve member 20*, when in its .fully raised position, completely closes the connection between the container 10v and the dip pipe 16.

The arrangements set forth and described efficiently maintain an undisturbed flow of the liquid between the gasholder where the liquid is first collected and the outside collecting tank, which is essential to the efficient operation-of gasholders of the indicated type. At the same time, the amount of the flowing liquid can be adjusted so as to supply the liquid in the desired amount to any of the outside collecting tanks. The construction furthermore provides an eflicientarrangement whereby escape of as is prevented in case the collecting tank s ould e pumped dry. In addition to this, the flexible connections of the pipe 17 with the container 10 and the tank 15 are such that in case of settlement of the gas holder foundation the joints between the connecting pipe and sald container and tank will remain undisturbed. Furthermore the collecting tanks and their attachments may be readily shut ofi or disconnected from the asholder to permit repairs and the like and in addition interference with the proper operation of the floats whereby the pumps are controlled is positively prevented at all times, including freezing weather.

Various changes in the specific form shown and described'may be made within the scope of the claims without departing from the spirit of my invention.
