Specification of Lettersratent. Patented Dee. 2'7, 1910. Application filed October 8, 1910. Serial No. 588,124.

To alltuhom it concern: I

Be it known that I, Cnanmes W. Karena,

a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Im rovements in Acetylene-Gas Containers, 0 which the following is a specification. 4

. This invention relates to the preparation of acet lene gas containers so that they can be safe y shipped and handled in the use of the gas, and more particularly the invention relates to the filling substance with which the cylinder orv other receptacle is packed to divide its chamber into minute spaces or interstices to be occupied by the gas and acetone or other solvent of the gas.

The objects of the invention are to secure 8. I I I 'l in as in pgef c' us ension or perfectly sub-divided condition; thus secure complete safety; to obtain a filler which can be easily put into the cylinder or other receptacle and which completely fills the same; to secure a durable filler, which will not deteriorate in handling the containers; to secure an inexpensive filler; and to obtain other advantages and results as may be brought out in t e following description.

In carrying out my invention, I mix laster of aris with a large excess of wa er, or exa e a out seven parts of water to SIX parts of plaster of paris. This makes a i%uid of about the consistency of cream, or w ich can be readilyvpoured. cylinder or other receptacle with the liquid, preferably by pouring it through the valve opening of the c linder, and et 1t set or harden. After e mixture has set sufliwa r in it is driven 0 is left a filhn who as Y roughu,,itsel-f-innnmera In other words, it v 'ke a s but the holes are very minute and evenly distributed; in fact, the said spaces or interstices are It is'an important point of my improved .filler that while it is rigid enough to maintain its shape against sagging. either before I then fill the RQGSDDJIlter- V too minute to be seen withthe naked eye. Such a filler readily receives or after being wet with the acetone or other solvent of the gas andagainst all-jars and shocks of the containers as a whole, it is at the same time impressible so that it can be dented at its outer surface without affecting the rest of the filler. In other words, a blow upon the filler will only cause an indentation without cracking or fracturing the filler as a Whole, and such indentation closely fits the instrument which has been driven into the filler or with which the blow Examiw .was given. The-result of this in practice is that a blow or impact upon the outside of the cylinder suflicient to dent it simply dents the filler inside the cylinder correspondingly and does not crack, crumble or fracture the filler otherwise. In other words, the effect of the blow or impact is restricted to the place which is hit or indented and not transmitted to the .rest of the filler, 'or the filler is non-frangible by the same means-to'which it is impressible.

Furthermore, my im roved filler because of its fine uniformly istributed spaces or interstices holds the solvent of the gas in suspension very effectively and reduces its loss by being blown out of the container with the escaping gas, since the gas releases itself slowly from my improved filler.

The surplus water may be driven oifby heating, by passing warm air through the cylinder containing the set filler, or any other means commonly employed for similar pur oses', or any combinatlon of two or more of t ese means. I have found that simply heating to about 180 degrees Fahrenheit will produce satisfactory results.

The plaster of paris may be used alone, or there may be mixed with it any other substances, such as infusorial earth, magnesia, charcoal, asbes as, W vicestone, and so orth, w W] vary its we or a sorbent properties. I also use the term plaster of pans to include what is known as Keene cement or gypsum burned or calcined with alum, calcium sulfate, and other plasters which are simply slight variations of plaster of paris and will produce the same'characteristics in a filler as those above described.

The advantages of my filler are that it is molded in the cylinder or other receptacle and therefore completely fills the same; that it can be poured into the cylinder through the usual valve opening,

and thereforeafter l filler; that t e filler readily the cylinder has been finished and tested; that the distribution of the minute spaces throughout the filler is even, uniform and unchangeable; that the filler is rigid'enough 5 to maintain its shape against sagging, jars,

shocks, and the like and yet is at the same time impressible so that the cylinder or other receptacle can be dented at its outside without afiectin the safety qualities of the absorbs the solvent and gas and retains 1t; that it is perfectly safe, and that it is cheap.

A filler of my improved composition can of course be molded or cast mdependent 1.5 of a cylinder or other receptacle and after such shapes w drying be placed in the same and packed with asbestos or other substances, as in common. In such a case the filler could be molded in one Ipiece or in several pieces, and

ich are well-known. I refer, however, to mold or cast the filler directly in the cylinder or other receptacle as above set forth, so that it forms an integral core completely filling the cylinder and in '25 intimate contact therewith at all points of its inner surface. In any. event, the filler must be a solid or imperforate mass, that is, without borings or holes of any kind except the minute spaces or cells invisible to the 80 naked eye which are formed naturally, and

if it is composed of several pieces put in one cylinder there must be no spaces or openings left between or around them. Y

By the term acetylene gas I mean to include any gas having simllar explosive properties whether in a normal condition, or compressed, or liquefied, or dissolved in a li 'u1d, or the like. Having thus described the invention, what I claim is 1. A filler for acetylene gas containers, containing plaster of paris set in an impressible non-frangible form.

2. In an acetylene gas container, the combination with a receptacle, of a filler in said ller in said chamber in an imperforate filling terior cham er, of an integral imperforate core filling t e said chamber and containing plaster of paris set in an impressible non-.

frangible form.

In testimony whereof I afiix my signature in presence of two witnesses.

CHARLES W. KAISER.
