ments in Gas-Tanks, of which the following is a specification.

The purpose of a porous filling for acetyi lene gas tanks is well known in the art. This filling is commonly embodied in formed asbestos fiber disks designed to fit closely Within the cylindrical tank. These disks are not solid or rigid clear through, there being simply acrust formed on their sur. faces to hold them in the desired shape, so that no positive support is provided for the fiber forming the inner or central portions of the disks. This material is liable to loosen up, shift, or separate and form voids orv pockets of suoli size as to become dangerous, it being well recognized that even a small quantity of gas collecting in a pocket or space unobstructed by the threads or liber of the filling material is liable to set up such disintegration of the elementsl as to -produce a destructive explosion. T he tendency to form these objectionable pockets or spaces is especially great in tanks used on gantomobiles, the constant motion and not infrequentl jarring and jolting tending to cause the filling'to settle or separate and produce ther objectionable spaces. A further source of danger is the denting or battering of thetanks. V An 'indentation Will form a like depression in the filling, and if the indented metal springs back a space or pocket remains in the filling.

The object of the present invention is to so support or sustain the tilling as to render its separation'or settling and the formation of spaces or voids quite impossible.

A further object is to guard against the formation of such spaces resulting from indenting the tank by causing the filling to adhere to its inner surface, so that if a dent occurs and the metal springs back, the filling 5 with it and no void will time provide 'spaces outside of lbody aswell as therein for confining porous filling material. .`\nd the latter' is preferably cenicn-ted to all surfaces of the support as Well as to the interior of the tank, thereby fully sustaining it from all directions andprevent- 6o ing disj'ilaccment.

ln the accomj'ianying drawings, Figure l is a perspective ot' a filling support constructed in accordancewith the invention, f and Fig. 2 is a cross section of a tank show-65 ing thc support of Figli thcrein and with the several spaces defined thereby filled ywith porous material. l `igx 3 is a view similar to Fig "2f, illustrating a. support of modified form, and Fig. 4 is a detail of the modificaf- 70 tion of Fig. 3. l

`Referring to the drawings, 2 designates a cylindrical gas tank of usual construction, and 3 is porous material packed'therein. This filling may consist of asbestos fiber. or asbestos mixed with cotton, or any other nmtcrial that will provide the requisite compact porous mass, permitting free circulation of thc gas-carrying solvent. f

The filling support may be variously onstructed to so hold up or sustain the packed material to prevent it from settling, sepa.- rating or dividing and forming pockets orv voids, and at the same time not interfere with the free circulation of the solvent. A desirable embodimentprovides for bridging or bracing the support against the Walls ot' the cylinder in such manner as to hold it rigid. y i In the adaptation shown in Figs. 1 and 2, 90 the support isconstructed of stiliened or l formed asbestos or asbestos board,`and consists of a cylindrical or'holliow body-portion 4, from which projectl'tthe longitudinal blade-like extensions or wings 5, lpreferably disposed radially, as shown, and of a size to closely fit Within tile cylinder-.or tank 2. This formation provides spaces on the eX- terior of body 4. between adjacent wings, and thesespaces, as weil as the interior of body 4, are packedgvith the fibrous filling, and the body being formed of asbestos, the solvent may circulateA therethrough as well as through the filling.

The loose filling is `cemented to the inner surfaces ofthe tank, as indicated at 6, and

also to all surfaces of the support, as shown at 7 thus still further fixingand holdin the filling throughout the entire space o the tank. And with the filling thus cemented if 119 l tively support-ing the filling.

the cylinder is dented and the metal springs 4haelt', the 'filling follows the metal at such time. YVithout this adherence such indentation of the shell would similarly indentA the lilling, particularly with. the latter of formed construction as heretofore, thus prothe perforations permitting tree circulation of the solvent and at the same time posi- Froni the foregoing it Will he seen that the supportniay he constructed of various materials. And while theA preferred shape is hereshown, the invention is not limited thereto.

The supports may he dealtin as an article of manufacture separately from -the tanks in which they are placed, as Will he understood.
