JOHN H. EICHLER AND JULIUS BECKER, OF SAN FRANUMOO, (lALlfllOltllIA.
SPECIFICATION forming part of Letters Patent 1%! 0. 79:3,n30, dated July it, 1905.
Application filed July 26, 1904. Serial No, 218,182-
To all whom 71/; may concern.-
Be it known that we, JOHN H. Brennan, a citizen of the United States of America, and JULIUs BECKER, a subject of the German 5 Emperor, both residents of the city and county of San Francisco and State oi California, have invented certain new and. useful Improvements in Acetylene-Gas Machines, of which the following is a specification.
[ This invention relates to apparatus for generating gas for illuminating purposes From calcium carbid, commonly known as acetylene-gas machines; and the invention has for its object chiefly the produc I tion of a machine or apparatus for family use and in situations where a self-regulating and. safe machine of simple construction is required.
In this machine the gas is generated only in such quantity as the consumption calls for, and the production is regulated automatically by the rapidity with which. the gas is drawn oil for use. The machine is there fore self-regulating in this respect and the usual storage-tank is dispensed with. This feature removes the great and principal source of danger which is connected with all machines that generate the gas in quantities to be distributed for use from. a tank or gasometer. The substance from which. the gas is made is lied to the machine in varying quantities as called for by the quantity of gas to be supplied, and the feed is regulated directly and automatically by the consumption of the 3 5 gas. Provision is also made for cleaning andv drying the generated gas directly in the machine between the generating-chamber and the distributing space or chamber from which the gas is drawn oil for use.
The nature of our said invention and the manner in which we proceed to construct, apply, and carry out the same are described at length in the following description and afterward pointed out in the claims at the end of 4.5 this specification, reference beng had. to the drawings forming part thereof.
Illn the said drawings, Figure 1 is an elevation. in longitudinal section of a gas-machine embodying these implements. Fig. 2 is a 5o sectional View of the hell. or inverted cylinder that confines the gas. big. 3 is a plan of one 0]. the perloraled dislcs ol the purifying device, and Fig. 4t a side elevation of Fig. 3.
The )rinci .)al parts of the machine coinprise the shell or body A, the bell or inverted 5 5 cylinder B, and the holder 0 for the calcium. carbid.
.l.he body A contains the generating chanu her or compartment D and th e annular space E, in. which the end 0]. the inverted gas-.hold- 6o ing cylinder B is closed by the confined body o'l water ill. The s )aee ill for this water seal is divided from the generating-chamber l) and the space above it within. the inverted cylil'ider by a standing wall ll, concentric with the surroumling stationaryshell or body and by a horizontal partition G, ol which the inner cylinder ll may be a lixed or permanent part. Inv the center of the horizontal partition a standing tube ll rises li'rom an opening in. the partition, and its open top end stands on. a level with the top of the inner wall ll, or nearly so. This standing tube being open at both ends forms a passage for the generated gas from the generating-chamber upward 7 5 through thehorizontal partition to the con-- lined space under the movable cylinder B, and through this central opening the calciumv carbid is led from the holder (1 above. The space between the stairnling tube ll and the surrounding wall F is utilized for a gas clean.- ing and drying compartment, for which. purpose it is filled with. some suitable substance or material conilined betweenv perforated. disks I, that are supported one upon. another 8 5 at intervals apart by legs K on the under side 01 each dish. The substance used For this purpose is geiuirally composed 0]. or contains chlorate ol lime.
The calciurn-carbid. holder C a separate vesselo'F cylindrical sln'tpe, with. a sloping bot tom and an outlet in the centerol the bottom. it is supported above the gas-remdvirrg eompartmel'it by means of legs or standards socured to the body oil. the machine, sullieient room being all'ol'ded under the lmlder for the cylinder ll to rise and iliall under variations in. the quantity of gas confined in the space be neath.
The supply 01. calcium carbid to the gencr- I00 ating-chamber is varied in quantity, according to the rapidity with which the generated gas is drawn off for use, and is controlled directly by the rising and falling motions of the inverted cylinder by the following simple and l efl ective means: In the center of the closed top of the movable cylinder B an opening is surrounded by a rim 1), from which a tube P extends downwardly into the stationary standing tube H, and from the neck 19 a flexible tube S, extending upward, connects with the outlet in the bottom of the carbid-holder C. This tube is connected to the standing rim p and to a neck t, surrounding the outlet in the bottom of the holder, by slip-joints and clamping-rings V. It is made of a length of rubber tubing or other similar flexible material that will allow the tube to bend and collapse at some point between the two ends, and thus entirely close or reduce the size of the passage through the tube by the upward movement of the cylinder B and in degree according to the extent of such upward movement. For this purpose the tube S should be of proper length to hang perpendicularly down and maintain a passage through it of full area, while the cylinder B remains in its lowest position, and from that position the cylinder, rising under the pressure of the accumulating gas, reduces the size of the outlet passage from the bottom of the holder by con tracting or bending the flexible walls of the assage. This has the effect to reduce or cut off the supply of calcium carbid in propor tion to the rising movement of the cylinder B and also to cut off the same as often as the cylinder is elevated by the accumulating gas to a given point.
The holder C is filled through an aperture w in the top, closed by a screw-cap, and this being the only opening in the holder excepting the outlet in the bottom, that is connected directly with the conflned space under the cylinderB, the danger arising from the escape of gas from the holder or from the confined space below it is entirely removed.
Provision is made for replenishing the generating-chamber with water by an inlet-tube R, entering the side of the shell near the bottom of this chamber and extending perpendicularly upward on the side.
The generated gas is drawn ofl through a pipe coupled to an outlet in the side of the shell A at a point above the horizontal partition G, so that the gas is caused to pass through the cleaning and drying material before it can find an exit at the outlet. A cock y is provided in the pipe IV for regulating the outflow of gas.
