ALEXANDER FREDERICK JENKINS, 0F BALTIMORE, MARYLAND.

CARBIDE HOLDER FOR ACETYLENE GENERATORS.

Application filed January 15, 1919.

To all whom it may concern Be it known that I, ALEXANDER F. JEN- KINS, a citizen of the United States of America, residing in the city of Baltimore, State of Maryland, have invented certain new and useful Improvements in Carbide Holders for Acetylene Generators, of which the following is a specification.

This application is in part a continuation of-that filedby me April 17, 1918, Serial No. 229,109. H

The present invention relates to a car bide container or pocket;, for holding carbide for treatment with water in the generation of acetylene gas, the pocket herein referred to being employed in..the same capacityas other carbide pockets known to the art, those shown in the application cited above and in my application, No. 229,107, filed April 17, 1918 and my United States Patent 1,292,327. The various applications referred to relate to carbide holders having perforated tapering pockets, i.-e., pockets of downwardlyreduced cross-section arranged in staggered and overlapping relation to give uniformity of generation of gas and easy filling and emptying of. the pockets. By this arrangement the carbide and ash are conveniently supported, allowing sufficient room for expansion in the consumption of the carbide forming the said refuse or ash which is of a considerably greater volume than the carbide. By uniform generation I mean generation of gas in quantities bearing a substantially uniform relation to the amount withdrawn.

In the various prior applications I have shown pockets of rigid material. These pockets have, as already pointed out, important advantages in that they are easy to empty of the consumed carbide or ash which is inclined to adhere to the pocket, and they afford a large area at the. top for support of the ash and liquid. Also the taper of the overlying pockets provides an excessive clearance, making access to the pockets below for filling and emptying easy and convenient.

Along the lines of the development in this art thus defined,I havediscovered that Serial No. 271,216.

a flexible pocket which may be of separate interlocking members, preferably closed links, or otherwise made completely flexible, offers important advantages. Such a receptacle is adapted for arrangement in accordance with the disclosure of my aforesaid copending applications, in overlapping relation to give generation at uniform pressure and in a high degree to contribute to all the advantages obtained by the various arrangements of tapering pockets outlined in the above-cited applications. But an important advantage, not inherent in the devices thus disclosed, relates to the flexibility of the pocket, making it possible to detach the ash, particularly that which tends to ad here to the walls of the pocket, merely by striking it, thus changing the configuration of the walls of the receptacle and breaking and releasing any encrusted material which may adhere to them.

Another advantage of the flexible pockets is that they may be so made as to render the entire carbide holder reversible, that is, the holder being inverted in the process of emptying the ash, the pockets, relatively speaking, turn inside out and may be filled and operated in this position, avoiding the extra step in the refilling operation which consists in returning the carbide container to upright position after it has been emptied.

In the accompanying drawing 1 have illustrated a carbide container constructed in accordance with my invention.

Figure 1 is an elevation of a support with chain mesh pockets fragmentarily shown for convenience in illustration.

Figure 2 illustrates my flexible mesh pockets applied to a support composed of separator members.

- Referring to the drawing, the carbide container or pocket, which is the subject of my invention, consists of a bag 20 of flexible mesh or separate interlocking members shown in the form of closed or continuous links 21 which compose a fabric termed chain mesh. Each pocket is supported on an open frame. 22, preferably of wire or similarmaterial, the edge of the top opening in the bag 20 being secured to the frame in any convenient manner as by having the top links 27 of the mesh material which forms the bag encircle the wire. The frame in turn is adapted to be secured to any kind More particularly, the device illustratedconsists of four, separators or two intersecting separators or plates 25 arranged at 90 or any suitable number of plates at any corresponding angle. Between, on or applied to, the plates are supports 26. These are preferably of wire or similar material, but may be otherwise formed, each one being adapted to support the mouth of a chain mesh bag 20 which constitutes the corresponding pocket.

In the form illustrated, which is the preferredconstruction, the top links 27 of the mesh forming the mouth of the bag or pocket, encircle the wire or similarmaterial forming the frame, and the bag or pocket preferably hangs freely from this frame,

'not being otherwise secured to the separa tor plates so that the pocket is free to yield when struck for the purpose of breaking up the ash, and also is free to turn inside out when the carbide'holder is inverted in emptying, making it possible to fill the pockets in what may be. termed an invertedposition and avoid the necessity for returnin'g them to the original or what may be termed the upright position, the whole containerbeing preferably'made symmetrical so thatthe upright. and inverted positions referred to are in fact indistinguishable. This feature or advantage is not confined to the pocket illus trated in Figure 2, as the ocket shown in Figure 1 is equally capable of being used in inverted position, and other types of'chain carbide pockets may be so constructed,

The manner of using the pocketis obvious to those skilled in the art. It is filled with carbide to which water is applied for generation of acetylene gas by gradual immersion of the carbide in any manner. The mesh permits free entrance of the water and free escape of the water, giving every possible facility for uniform generation or uniform response to the demand, including quick flow of the water to the carbide and quick draining of the water from the carbide, which results in immediate response of the generator to variation in the rate of consumption of the gas by giving a quick pick-up of generation and preventing after-generation. Another and in fact a most important advantage of this type of pocket over those known in the art and described in my copending applications is that already recited, i. e., that the ash which. tends to ,encrust and adhere to the walls of the pocket maybe easily broken and released because of the complete fiexi bility 9f the pocket py striking the pocket and changing its form i. e., crushing it. Also, the oyerhanging ;pockets because of this flexibility permit easy access to those below for filling, etc, q 7

Having thus described a single apparatus embodying my invention, I desire to have it understood that thefspec'ific't'erms are used ina descriptivqsens'e for the purpose of enabling those skilled in "the art to practice the invention and not withthegpurpose oflimiting the scope of the protection to be granted. 7 1
