vested in the Alie l 'l Claim. The present 'invention relates to receptacles such as tanks, cans or similar containers for combustible liquids, such as petrol, benzole, ethyl;- ether or the like, having a low boiling point and forming explosive vapours, and more particularly to tanks of vehicles, such as motor cars, aeroplanes and the like.

The object of my present invention is to' develop a tank for the above mentioned liquids whichoffers a maximum safety' against explosions.

Now, my invention provides for to arrange in side the tank a filling ofan inorganic andv noncombustible brous material which is neutral against the liquid that is which is vnot attacked by the liquid to be stored in the tank, preferably a filling of loose glasswool.

Furthermore my invention comprehends to arrange the filling of glass wool or the like within the tank in special chambers or cells which are n Property Custodian `Application March 21, 1939, Serial No. 263,133

In. Germany August 19, 1935 n 1. On the top, the tank is provided with a charging and discharging opening 2, which may be closed by a lid 3. In the interior of the tank I there is arranged a number of vertical and horizontal Ipartitions 4 which consist for instance of wire cloth, perforated sheets or of another suitable material which is well permeable for the liquid and which hasthe necessary strength in order to keep the glass wool filling in proper pon sition and to prevent it from being upset and sticking together.

Suitably the partitions 4 are connected with one another to a framing before the assemblage of the tank I by means of bars 5 which are fastened by welding or in another appropriate manner. The framing is then inserted into the tank for example before fixing the bottom 6 or the top 1 into position in such a way that the former formed by permeable partitions 'extending through the interior of said container or tank.

The filling of loose glass wool according to my invention is more advantageous than a filling of organicfi-brous material insofar as the filling is entirely neutral and is neither attacked by the liquid stored in the tank nor altered in any way. This advantage of the glass-wool-flling is of utmost importance for fuel tanks of vehicles or the like, since the fuel or petrol will not be contaminated by the filling similar non-combustible material being 'neutral against the liquid to be stored.

The arrangement of several chambers or cells which are formed for the filling by partitions permeable for the-liquid within the container or tank' prevents that the filling will stick together or become upset due to shocks or the like, whereby it would lose its efficiency as lled with explosive vapours would be formed in the tank.

the glass Wool or av then a free space With the above and other objects and features of my present invention in view, I will now describe several modes of carrying out my' invention on the lines of the accompanying drawing in which:

Figure 1 shows a liquid tank built according to the present invention;

Figure 2 is a horizontal section through a tank of another mode of construction and Figure 3 nally shows in an enlarged scale a vertical section according to the present invention.

The liquid tank itself is marked I in Figure vertical section through a.

through a lpart of a tank built titions is filled-up with derneath the `is situated in 'the tank allowing a small clearance.

The space between the partitions namely the individual chambers or cells formed by the parloose-glass wool 8 or another suitable material in :such a manner that preferably the whole interior of the tank, eventually with the exception of a small space 9 uninlet 2 is filled with glass wool. The space 9 may for instance be formed by a cylindrical body I0 of perforated sheet which is fastened to the frame carrying the loose glass wool or the like.

The quantity of glass wool or of a similar lling material to be provided for in the tank, depends upon the individual purpose for which the tank will be used. For the petrol tanks of vehicles, the quantity of filling material may .preferably be such that about 5 per cent of the interior of the tank are taken-up by the filling material.

In Figure 2, the tank is marked 20. The filling material 2l at this kind of construction is placed between a spiral coiling of wire cloth 22which be suitably strengthened by rods 23 or the like. The coiling as well as the filling material are manufactured before the completion of the the middle which reaches into the interior of the container is facilitated. As shown in Figure 3, the tank 30 has in the middle a closeable charging hole 3i in which is arranged a strainer 32 reaching down into the interior of the petrol tank or the like.

At the kind oi' construction according to Figure 3, there serve as carrier for the tllling material two wire coilings 33, 34 which at the side facing each other possess a recess 35, 33 which after the insertion ot the coilings into the tank leave free an essentially cylindrical space whereby the distribution o! the liquid charged into the tank is made easier. Also according to Figure 3,

each Wire cloth coiling 33, 34 is equipped with' stiilenings 31 so that the coiling maintains its proper shape even then i! the tank or container is exposed to heavy shocks which are for instance unavoidable at motor lorries.

Finally I may say'that it is also possible to arrange the lling o! loose glass wool or the like in the upper part of the tank or container only, i. e. in the zones near the inlet opening provided for in or near the cover of the tank. In this case, the illllng surrounding the inlet opening will suppress any explosion of the vapours near the inlet and will safeguard the liquid in the lower part oi' the tank or container.

I wish it to be understood that I do not desire to be limited to the details o! construction shown and described, for obvious modiiications will ocour to a person skilled in the art. The right to make the subsequent claim is hereby expressly reserved.

What I claim is:

A tank for the storing and dispensing o! comseparately formed umts of loosely packed inorsanic non-combustible nbrous material reiniorced by webs of periorate metallic' material, said unitsl abutting adjacent said opening. registering recesses i'ormed in the abutting portions of said units adjacent said opening to provide an open and unobstructed compartment communicating with said opening to aid in the distribution of liquid throughout said tank.

CONRAD HELD.
