Application filed March 9, 1911.. Serial No. 613,420.

To all wzom t may concern Be. it known that I, Orro SCHMIDT, a. subject ot the KingI of Prussia, of 4 Kurzestrasse, Haspe, in lVestphalia, in the Kingdom of Prussia, Empire ot' Germany, master coppersmith, have invented certain new and useful Improvements in Apparatus tor lnexplosively Storing and l)rawinj Oil' Igni'terous Liquids; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which itappertains to make and use the same.

My present invention relates to anapparatus, or plant, for inexplosively storing and drawing-ott' ignit'erous liquids, which is operated by means of water-1n'essure in such a manner that the bulk. of the displaced ivniferous liquid, such as benzin, coal-oil or t'iellike, is replaced by the watel as usual, and which plant is provided with means executing` their several functions automatically as soon as the air surrounding the apparatus reaches a certain degree ol. temperature, or `a tire breaks out in its neighborhood. In the first. instance the igniterous liquid in the storage-tank will be cooled through its bodily contact with the water, but in the second instance, in addition to this, the storage-tank will be energetically cooled-ott' from withoutI by sprinklingmeans similar to those employed tor stages and other rooms more or less likely to take tire. The possibility of an explosion is tur ther minimized by the tact, that the water employed for displacing the ignit'erous liq uid enters the storage-tank through a standpipe which surrounds the discharge-pipe ot the igniferons liquid so completely, that the latter is kept cool at all times. Besides this, means are provided, capable of leading-ofi' any volati'le `gases and vapors which may collect and attain a pressure which, if not duly reduced or relieved, might prove danzgjerous to the apparatus or the whole plant.. ln this manner it is made possible to lfeep the igniferous liquid even in presence of a tire so cool as to prevent its explosion and thus most effectively prevent the loss of lite and property.

In the accomlmuying' drawinf's:-Figure 1 is a vertical sectional view ot my invention, Fig. 2 is an elevation of the means elnployed for usually adniittin;Y the water for ed arm displacing the igniferous liquid, or coollng the latter and the storage-tank m case the combined water-outlet and dischargepipe. Y V

Upon the top of the storage-tank l an `mfertlow-ehamber 2 is arranged, which in turn surn'iounted by a casting 3. The latter supports a stand-pipe d carried upward through the roof of the building, and a pipe 5 which extends downward and ends within a short distance above the bottom ot' the overtlow-chamber 2. lVithin said casting` 3, stand-pipe t and pipe 5 the diseharge-colunm is arranged, which passes upward above the highest tap 7 and downward through the bottom of the overflowchamber into the storage-tank 1, whereas itis enlarged within the casting' 3 to form a double-seated valve-casing' 8 to which the .feed-pipe 9 connected.' Through the latter the igniterous liquid is forced from the barrel l() by means ot the force-'pump 11 in the usual manner.' lVi thin the easing S the valvescats l2 and 13 are formed, the former above and the latter below the lamide-sleeve let. In thisI sleeve a guide-rod 15 is guided which ax-ries the valves 1G and 17 arranged Vin such a` manuel', that when the one is seated the other is opened, and vice versa;

or both valvesare open at the same time, as shown n1 the drawing. The `guide-rod l5 also passes through the flame-extinguisher 1S arranged at the lower end ot the disch-arg0-column G and is further guided in a bracket 19 secured to the bottom of the storage-tank 1. To keep the valves 16 and 17 in their normal position, said valverod is balanced by means of t-he weighted lever 2O always duly returned to its normal position by the aid of its weight- 20 acting as a pendulum. r1`he valve-rod l5 pets 21 and between which a tloat; or swinnner 23 ot such specific gravity is arranged, that itwill not be carried upward. by the igniterous liquid, but will always vremain in Contact vith tho body of water which carries and discharges said liquid is further provided with tap- 30 and. ma

of 09mm ngef which @amies at its en hi; i? uffi is nsened 'mth 63h@ 'l th@ whQe by means c x it lover @mi to che fiom' 3:3 by the 10 hook 510 0s. the luie., The tue m' mais of mail@ mi wfg ch .is easily stand- )i )e at and V artly downward throiieh t l i, i

the pipe 55 to the perforated coiled pipe or sprinkler G ar ang'cd on top olI the storagetank l. That part of the water which pas es through the valve 5l into .the stand-pipe 4 flows along with the water from the bypasspipe 3S to the tank to cool the contents.

thereof, whereas the part ot the water which flows through the pipe flows into the sprinkler '56. from which it runs in small streamlets all over the top and sides ot' the tank l to keep the latter and in consequence thereof its contentsv cool. To n'iake the automatically operating` water-suppliers arranged upon each floor act 4independently of each other, their pipes are led to a head common to both, with which the sprinkler 56 is connected. lty will thus be seen that the plant protects itselt autoinatically against the. dangers entailed by a tire., since ity not only compels the water to toi-m a cooling \\ater-mantle around the discharge-column ot the liquid and around the shell of the storage-tank, hut also brings it. into bodily Contact witlrthe liquid itself notwithstanding the fact, that the cock tl, usually admitting the water for displacing;- the liquid, closed.v By means ot thisl invention it is thus made possible to obtain the greatest protection against the destructive consequences ot an explosion ot the igniterous liquid, since the latter will always he. kept oolow the dangerous temperature so lon; aS The autonnitically operating` water-suppliers arc not destroyed.
