a. i u l I ERNST .HURLBRINK, OF FRIEDENA'U, BERLIN, GERMANY;
CONTAINER FOR INFLAMMABLE LIQUIDS.
To all whom it mayconoem:
Be it known that I, EnNsT HURLBRINK, a subject of the Emperor of Germany, and resident of Friedenau, Berlin, Germany; have invented certainnew. and useful Improvements in Containers; for Inflammable Liquids, cation.
. My invention relates to containers for inof which the following is a specififlammable liquids and has for its object to features of novelty will be pointed out in the appended claims.
Reference is to be had to the accompanying drawings in which Figure 1 is a central longitudinal section of my improved container with the parts in the position assumed during outflow of the contents; Fig. 2 is a similar view showing the container in position for filling; Fig. 3 is a horizontal section on the line are sectional views similar to Fig. 1 of two different forms of my improvement; Fi 6 is a detail section on the line (r-D of ig. 5; Fig. 7 is an elevation with parts in section of still another form of my lnvention; and Fig. 8 is a detail view of a difierent valve arrangement.
Referring more particularly to Figs.
any suitable material preferably lined on the inside with an insulating latterin turn being also preferably covered with a suitable covering 3* to protect the said of a cap 5 which ,is preferably anantegra1- part of the wall 6 of said container, the
said cap 5 being provided witha pipelor tube 7 communicatingwith theechamber 4..
for connection either with" a source of gas-underpressure' or with a supwill be more fu ly explained hereinafter. The. chamber 4 also contains a tilbeS'Carfied by the wall 6 into apluralit of U-bowsand at and adapted pl of the particular liquid as and bent right angles ias Indicate at 9 to form what Specification of Letters Patent.
Application filed May 27, 1914. Serial N 0. 841,192. 7
A-B of Fig. 1; Figs..4 and 5 11 2 and'3 the container comprises a shell 1- of material 3, the
forced into Patented Feb. 25,- 1919.
might be termed a coil, the said tube 8 hav-. ing 1ts one end 10 located in close proximity to the wall 6 in communication with thefl chamber 4 and its other end 11 connected with the chamber 2. Avalve casing 12 is located within the. chamber 4 but has no communication therewith and is provided with a valve seat 16, controlled by a valve '14, the latter being carried by a screw-threaded stem 13 adapted to be rotated by means of, a hand wheel 15. The valve seat 16 is located adjacent to one end of a tube 17 extending from e I said casing 12 through the wall 6 into a valve chamber 18 located interiorly of the container 1 in the chamber 2 thereof. This valve chamber 18 contains a ball-valve 19 normally pressed, by means'of a coil spring 20, upon a valve-seat 21 located adjacent to the end of a pipe 23 communicating with the valve-chamber l8 and having itsend 24 located in close proximity to the bottom of the end 24 closely'adj acent to the side wall thereof as clearly shown in Fig. 1. The valve 'casing 12 is further dprovided with an outlet container and being bent at 23 to bring said with an opening 26 which normally is sealed by means of a closure 27 constructed of a material which is easily fused or melted or otherwise destroyed by heat or flame. A
safety valve- 30 controlling an aperture 28 'in the chamber 4 and itself controlled by a coil spring 29 may also. be provided if de- Whenit is desired to utilize all or a portion of the liquid contained in the container 1' the same is placed in an upright position as shown in Fig. 1 and the pipe 7 is connected with a source of gaswhich is noninfiammable or which may be brought into contact .with the saidliquid without any harmful results; This as will fill the cham- 'ber 4 and if the valve 14 is opened by actuao ing: the handwheel 15, thesaid gas will be 8 and out of the end llgthereof into the the end lOand through the coil r05 'icha'mber 2. The pressure of said as. being i jthus brought to bear upon the li uid in'said.
chamber said'liquid will be timed into the end 24 and up through the pipe22 and after raising the valve 19 from the seat 21, against the tension of thesp'ring 20, passes": into the -;valve-chamber 18, and through the tube 17 and into the valve casing 12 and from thence out through the pipe 25 to the point or place of use.
If during such outfiowing of the liquid a fire should occur in the vicinity of the receptacle, the heat or flames therefrom will melt or otherwise destroy the closure 27 and thus open the chamber 2 to the atmosphere by way of the opening 26. As soon as this has occurred the gas entering through the pipe 7 into the chamber 4 instead of passing through the tube 8 into the chamber 2'will pass out of said chamber 4 through the opening 26 and the fiow of inflammable liquid through the pipe 25 will immediately and automatically cease. The insulating material 3 will protect the liquid remaining in the receptacle 1 from the effects of the fire or the heat therefrom so that all danger of explosion and additional fire is entirely obviated. If during operation of the receptacle the pressure of the gas entering through the tube 7 exceeds a predetermined point the safety valve 30 will be opened to relieve the same, it being understood that the tension of the spring 29 is computed accordingly.
' When it is desired to fill or replenish the receptacle 1 it is placed in a horizontal position as indicated in Fig. 2 with the valve 14 being open as shown, and the tube 7 connected with a source of liquid preferably under pressure. The end 10 of the tube 8 as illustrated is in its lowest possible position while the end 24 of the pipe 22 is raised to its highest position. In this condition the liquid is forced into the chamber 4 and through the tube 8 into the receptacle 1, the gas in the chamber 2, as the liquid level rises, being forced through the tube 22, valve chamber 1 8, tube 17, valve casing 12 and tube 25, the valve 19 being raised from the seat 21 by the said gas to make'this possible. If any liquid remains in the chamber 4 after the filling operation has been discontinued the same will be forced through the tube 8 into the receptacle by the pressure of the gas entering through the tube 7, the first time aquantity of liquid is again withdrawn in the manner described above.
As will beapparent from the foregoing the flow of the gas and of liquid during withdrawal of liquid from the receptacle and during the filling operation respectively is always in the same direction through the tubes or pi es 7, 8, 22, 17 and 25.
I It will urther be seen that the valve 19, constitutes an automatic safety device for preventing the liquid from unintentionally flowing from the receptacle when in a horizontal or any a proximately similar position, this being ue to the fact that the moment the valve 14 is opened atmospheric pressure will be added to that exerted by the spring 20 to maintain, said valve 19 firmly on its seat, thus preventing any air from reaching the chamber 2. At the same time said valve prevents any liquid from flowing through the pipe 22 from the said chamber 2.
The tube 8 in addition to its other functions constitutes an additional'safety device for preventing the liquid from unintentionally leaving the chamber 2 or from gaining access to theopen. For instance any air which might enter through the opening 26 after the closure 27 has been destroyed and finds its way into the tube 8 would be arrested by the pressure of the gas contained in the chamber 2 exerted as said gas sought to escape through said tube 8 so that the incoming air andthe outgoing gas would be balanced and the progress of both arrested. That is'the horizontal portion of the tube 8 acts as a fluid seal and arrests the progress of any air through said tube into the container. This is due to the pressure of the gas therein, the specific weight of which is greater than that of the air and thus prevents diffusion and withdrawal of the liquid. In other .words, the air is under normal pressure while the gas pressure is always in excess of said normal pressure so that a counterbalancing of pressures takes place between the two in the tube 8 which brings about a neutral effect and arrests the pro ress of both the gas and the air thus guar ing against the formation of a combustible mixture in the container by the inflow of air.
In the form of my invention shown in Fig. 4 the tube 8 is replaced by a ball-valve 31 contained in a casing 32 and controlling a passage 34 extending between the chamber 4 and said casing 32, the latter communicating with the chamber 2 by means of an aperture 33. The said ball valve 31 is normally maintained against its seat to close the passage 34 bymeans of a coil spring 35 and operates similar to the valve 19 although in a reverse direction. In other respects the construction of this form of my invention may be the same as the one first described.
1 This receptacle may be filled in-the same wayv as in the first formby reversing the operation as described above.
In Fig. 5 the valve 19 and its cooperating parts'are omitted and the pipes 17 and 22 are united and the latter is thus directly connected with the valve casing 12. The pipe 22 at some point within the chamber 2 is looped or bowed s0 asto extend at substan- Mi a. l
communicates with a valve tially right angles to the axis of the receptacle as indicated at 36 and 37 and so as to be inclined as illustrated at 38. This arrangement operates in the same n'ianner as the tube 8 and prevents air from rushing into the chamber 2 through the pipe when the valve 14 is opened. The construction and operation of this last form may otherwise be the same as the two forms first described both as to emptying and as to filling.
The valve 31 of Figs. 4 and 5, in case the closure 27 has been destroyed. also prevents air which may enter the chamber 4 from entering the chamber 2 and being substituted for the gas which may be contained in the upper part of the receptacle or rather the said chamber 2.
The form shown in Fig. 7 comprises for instance a wrought iron-receptacle or tank 1 having a cover 44 on which the valve casing 5 is located, the latter being divided into two chambers 4 and 4, one of which 4 is con nected with the tube and the other 4 with thetube 7 and which have no communication with each other. A valve 14 similar to and operated the same as the corresponding valve in Fig. 1 controls the connection between the chamber 4 and the tube 25, the chamber 4 in turn being connected with the interior of the receptacle 1 by means of a pipe 22 which at its lower end carries and casing located near the bottom of the receptacle 1. This casing contains one valve 19 controlling an axial passage and under the influence of a spring 20 and another valve 42 controlling a transverse passage and under the influence of a spring 43, the transverse passage last named establishing a connection between a chamber'41 and the pipe 22. A tube 8 corresponding to the tube 8 of Fig. 1 connects the chamber 4 with the interior of the receptarcle 1 and is bent into a horizontal coil with its exit end projecting upwardly.
To withdraw liquid from the receptacle of this last form a gas under pressure is forced through the tube? into the chamber 4 and from thence through the tube 8 into the interior of the receptacle 1. The pressure of said gas will thus be exerted on the liquid and will by way of the chamber 41 cause the said liquid to force the valve 42 against its seat to close the above mentioned transverse passage, while at the same time theliquid will raise'the valve 19 and thus pass throughthe axial passage controlled thereby,-through the pipe 22 andout of the passage 25, it being understood that thevalve 14 is open'to' make this possible; When filling the receptacle 1 the operation is the reverse: that is the liquid is caused to enter through the passage 25 and through the pipe 22 and will open the vvalve 42 and thus pass through the chamber 41 into the interiqr of the receptacle, whi1e at the same time the valve 19 will introduced into same, thus making it un-.
necessary to bring said receptacle to a horizontal position when it is desired to fill same.
Instead oi providing the tubes 8 with various forms of bends or bows for instance as in Figs. 1 and 7 the said tubes may be provided with transverse openings controlled by spring pressed flap valves 45 and 46 located respectively externally and internally of said tubes, the one end of which in this case would be sealed. Thus the valve 45 will open to permitgas to enter the interior of the receptacle when it is desired to withdraw liquid therefrom, the valve 46 meanwhile serving as an outlet valve. If desired ball valves or valves of other types might be substituted for the valves 45 and 46.
It will be seen in all the forms of my improvement that air is prevented from reaching the contents of the receptacle, even when the valve 14 is open or the closure 27 has been destroyed and the said contents are prevented from unintentionally flowing from said receptacle. My improved receptacles may thus not only be used for the purpose of permitting a safe withdrawal or filling in of inflammable liquids but may also be used for storing and transporting such liquids without danger of explosion or fire.
Various changes in the specific forms 7 shown and described may be made within the scope of the claims without departing from the spirit of my invention.
I claim:
1. A container of the kind described comprising a receptacle for the liquid, a tube therein, a valve chamber'connected with said tube, an axial operating valve and a trans verse operating valve in said chamber, said axial valve being opened by pressure as the liquid is withdrawn through said tube while said transverse valve remains closed and said transverse valve being opened by pres sure as liquid is introduced through said tube to fill the receptacle while said axial valve remains closed and means through which a gas may be introduced to expel said liquid through said tube and to permit said gas to escape as the receptacle is filled, the said transverse valve and axial valve acting independently of each other.
