To all whom it may concern:

Be it known that I, .PAUL Knssnmn, engineer, a citizen of the Em ire of Germany, residing at Steglitz, near Eerlin, Germany, have invented. certain new and useful Imrovements in Apparatus for Storing and .ischarging Inflammable Liquids, of which in w ich an intermediate tank having a' draw-ofi pipe and compressed gas supplly y "pipe communicates with the mam tan means of a non-return valve.

. In discharging ordrawinisog inflammai" y means 0 ble liquids from surface tan a protective gas under ressure, care must be taken toinsure positive introduction of the rotective gas into the tank during the wholh time of working, and also to stop the conveying of liquid automaticallyin case of the piping becom' leaky 'or breaking. More particularly, 1n the latter case the liquid must not be able to 'esca e from the tank by siphon action when suc action occurs in the discharge piping but on the contrary means must be provided 'to stop the siphon action automatically as soon as it starts. These requirements are fulfilled by the apparatus in accordance with this invention in which the intermediate tank is disposed within the main tank and the gassupply pipe is so arranged that it can communicate either with the gas-space in the main tank when the intermediate tank is being filled or with the source of the compressed gas when the liquid is to be discharged. r

One way of carrying out the invention is shown byway of example in the. accompanying drawing in which,

Figure 1 is a vertical section shown diagrammatically, and Figs. 2 and 3- are detail views in horizontal section.

Within the main tank 1 is arranged a smaller. liquid tank 2 connected b a check ornon-return valve 3 to the liqui chamber of the main tank. To the inner tank 2 is connecteda discharge or draw-01f pipe 4 extending to within a short distance of its base and carried outward through the cover 5 of the main tank, a jacket 6 surrounding the exterior portion of the pipe. In the discharge pipe 4 is formed a stop cock 7 of some well known safety type which is not liable to break. A compressed gas supply pipe 8 "opens into the cover of the inner tank 2 this plpe extending outward through the main tank cover 5 and having its exterior portion surrounded by ajacket pipe 9. The portion of the compressed gas pipe 8 situated outside the tank 1 is connected by means of a three way cock 10, to a pipe 11 leading to the source of supplyof compressed gas, and also to a pipe 13 connected to the gas space 12 in-the tank 1, this cock beingalso surrounded by a jacket pipe 14.

From the upper part ofthe discharge pipe 4' is branched off a pipe 15 opening into the gas space 12 of the tank 1, having a considerably smaller cross-section than the discharge pipe, a jacket pipe '16 connected to the jacket pipe 6, surrounding the pipe 15.] The jacket pipe 9 of the compressed gas pipe 8 1s connected by a branch pipe 17 to the gas supply pipe 11 and is also connected by a branch pipe 18 to the lower portion of the 'acket pipe 6. The jacket pipe 6 of the disc arge pipe 4 communicates b means of a' pipe 19, with the jacket 14 oft e pipe 13, and by means of a pipe 20 with the acket pipe 9 of the compressed gas pipe 8, so that the working pressure obtains in" all the jacket pipes. The charging pipe 21 of the tank -1 1s connected to its cover 5.

The working of the apparatus above described takes place in the following manner:W-hen there is no pressure, or only a comparatively small pressure, in the inner tank 2, the non-return valve 3 opens under the action of the hydrostatic pressure of the liquid contained in the tank 1, whereby the tank 2 is filled. If any protective gas re mains in the tank 2 from the previous dis- 1n wgich in that case acts as a gas outlet pipe I and owing to the three-way cock 10being set in the manner shown in Fig. 3 the gas passes through the return pipe 13 into the s chamber 12 of the tan In that way,

t e non-oxidizing compressed gas used for dischargingthe inflammable liquid constantly passes from the inner tank 2 into the tank 1; When the liquid is to be drawn off from the inner tank 2, the three-way cock in the compressed gas pipe 8, is brought into the position shown in Fig. 2, and the cock 7 opened, whereupon the compressed gas entering the tank 2 through the pipe 8, will force the liquid out through the pipe 4 and the open cock 7. During that time, comparatively small quantities of the liquid discharged through the pipe 4 from the tank 2, will return into the tank 1 through the ipe branched off from the discharge pipe 4, and in that way the si-- phoning action will be sto ped as soonas it starts. ince not only the discharge pipe 4, but also the compressed gas pi e 8', to ether with the gas return pipe 13 aonnect permanently to the gas chamber 12 of the tank and having its connection to the pipe 8 controlled, as by the cock 10) are jacketed by automatically pipes which are in constant communication with .the source of supply of the compressed gas, in the event of the gas pipes breakin the operation will be automatically stopped, owing to the blowing off of the compressed gas then taking place. Moreover in the event of the return pipe 13 breaking, its

jacket insures, even in that case, the pas-.

sage of the protective gas into the tank 1 during the refilling of the inner tank 2, and

consequently the passage of the protective gas from the innertank through the- pipes 8 and 13, into the tank 1 is also insured.

In refilling the inner tank, the protective gas escapes from said tank through, the pipe B into the pipe 13 (the cook 10 being at that time in the position shown in Fig. 3), and through the break or leak of the pipe 13 into the jacket pipe 14, thus reachlng the gas space of the tank 1. If the jacket pipe 14 were omitted, the gas would escape into I the atmosphere during'refilling, in case the return pipe 13 should be broken or leak..

What I claim is '1. In apparatus for storing and discharging inflammable liquids by means of a non-- oxidizing gas under pressure, the combination of a main surface tank adapted to contain inflammable liquid and gas under pressure, an inner tank disposed within the -main tank, a non-return valve establishing communication between said inner tank and the liquid contained in the mam tank, 2.
