ROYER LUCKENBACI'I, OE PHILADELPHIA, PENNSYLVANIA, ASSIGNOR, BY MESNE ASSIGNMENTS, TO CORNELIUS E. BAIRD, OF SAME PLACE.

ACE'TYLENE-GAS APPARATUS.

SPECIFICATION forming part of Letters Patent No. 584,946, dated June 22, 1897. Application filed December 23, 1896. Serial No. 616,795. (No model.)

To ctZl whom it may conceive.

Be it known that I, ROYER LUCKENBACH, a citizen of the United States, residing at the city of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Acetylene-Gas Apparatus,of which the following is a specification.

My'inventiou has relation to an apparatus for generating and controlling the production and distribution of acetylene gas for illuminating and other purposes and to means actuated from a gas-retort and connected with a gasometer and an auxiliary holder, whereby the escape or backflow of gas from either of said members into said retort and the atmosphere is prevented; and in such connection it relates to the construction and arrangement of such an apparatus for the said purposes.

The principal objects of my invention are, first, to provide a simple, economical, and efficient apparatus for the generation of a gas for illuminating and other purposes by the mutual decomposition of a fluid, as Water, with solid matter, as an acetylid or carbid, such as carbid of calcium,the apparatus being arranged with means operating automatically eration of gas in the retort to be supplied therefrom under perfect control and when the limit of capacity of the gasometer or holder has been reached so arranged as that the pipe connection from the retort with the gasometer or holder and with the water-supply to the retort is automatically cut off, thereby preventing further supply of gas to the gasometer or holder and also further generation of gas in the retort, and the gas remaining in the retort during the moments or period of cutoff to the said gasometer or holder being introduced into preferably an auxiliary receiver or holder, to be utilized therefrom or allowed to escape into the atmosphere, whereby, due to such arrangement of the apparatus, the dangers hitherto experienced in the handling of acetylene gas is prevented and an economical production and'utilization of the same insured, and, second, to provide in an apparatus for generating acetylene or other gas a retort with a removable cap or cover having rotatable clamping and lifting means associated therewith for controlling a valve adapted for cutting ofi or turning on the flow of gas from the gasometer or holder to a retort and from an auxiliary receiver or holder to the retort during the time of filling of said retort or while the cap or cover of the retort is removed, thereby preventing waste of the gas stored up within the gasometer or holder as Well as in the auxiliary receiver or holder.

My invention, stated in general terms, consists of an acetylene-gas apparatus when constructed and arranged in substantially the manner hereinafter described and claimed.

The nature and general scope of my invention will be more fully understood from the following description, taken in connection with the accompanying drawings, forming part hereof, in which Figure l is a view, partly in side elevation and partly in section, of an apparatus embodying main features of my invention. Fig. 2 is a top or plan view of the gas-retort and valved-pipe connections to and from said retort; and Fig. 3 is an elevational view of a portion of the retort partly broken away, showing the fluid-pipe entering the same, the cap of the retort clamped thereto, and in connection therewith means keyed to a valve which upon the rotary movement of the clamp and then removal of the same, the said valve in the pipe connection connecting the gasometer .or holder. with the retort and the latter with the auxiliary receiver or holder, are cut off or in from and to the retort to thereby prevent wasteful escape or loss of the generated and stored gas in the members of said apparatus.

Referring to the drawings, A is the gasometer, partially filled with water and provided with a dome or, adapted to extend downward into the same.

B is an auxiliary gas receiver or holder.

0 is a gas-retort, and D is a fluid or water reservoir. The retort O is mounted in a tripod standard 0 and rests upon lugs a, provided on the exterior surface of the retort. This retort has in the bottom thereof a stopcock 0 for drawing off matter therefrom as may be required, and at the top of the retort is a hinged cap or cover 0 resting on the flanged rim 0 of the retort by means of a clamp, which embraces the same by extending downward under the rim 0', as clearly illustrated in Figs. 1 and of the drawings. The gas is generated in the retort O by the intimate decomposition of a fluid, such as water, with a solid, as an acetylid or carbid. The water is permitted to flow into the retort O in, preferably, drop form through the pipef extending into said retort in the manner illustrated in Fig. 3, when the stop-cock f has been opened to afford such flow of the .iluid or water. The solid matter, such as acetylid or carbid, for example, carbid of calcium, or some other equivalent material, it is to be understood, is placed in the retort before the cap or cover is clamped thereto, as illustrated in Fig. l. \Vhen the water and carbid are brought together, there is given off as one of the elements of the decomposition what is known as acetylene gas, which is adapted to give a flame of great brilliancy or luminosity.

The auxiliary gas receiver or holder B is connected by means of a pipe 11 with the retort C, and which pipe preferably enters the holder 1 at the top thereof and is provided with a valve Z) of any preferred form, as clearly illustrated in Figs. 1 and 2 of the drawings. The gas generated in the retort C is conducted therefrom by means of the pipes f and e to the lower part of the gasometer or holder A, rising through the water therein and causing thereby the hell or dome a of the gasometer or holder A to be elevated and a vertical rod a to be actuated in a bearing o extending from the gasometer or holder A. The rod a is secured to an eye a which projects from the bell or dome a of the holder A. This rod a is pivoted at g to the curved lever-arm g, and the latter is in pivotal connection at g with the double bell-cranked levers F and F. These levers actuate valves f and f, which are connected with one another by means of a rod f. The said levers also control a valve 1) by means of a curved arm b the said valves f, f, and i) being located in the pipes f f, and I), loading, respectively, from the water or fluid reservoir to the retort G and from the retort to the gasometer or holder A, and also to the auxiliary gas receiver or holder 13, these valves being designated as the water and gas controlling valves of the apparatus and to the particular arrangement of which valves my present invention appertains and constitutes one of the main features thereof in conjunction with the dome of the gasometer for controlling the supply of water or fluid to the retort O, as well as the flow of the gas from the retort to the gasometer or holder A and to the auxiliary gas receiver or holder B or into the atmosphere.

The flow of the gas for utilization in any preferred manner is from the gasometer or holder A by means of the pipe 0. and from the auxiliary gas receiver or holder B by the pipe If. The clamp c of the retort is provided with a keyway c engaging the key e of the valve 0', located in the pipe connections f and Z), extending from the gasometer or holder to the retort C and from the latter to the auxiliary gas receiver or holder B, whereby upon the unloosening and rotary turning of the clamp a, normally engaging the cap of the retort C, the valve 0' is operated to cut off the baekflow of gas from the gasometer or holder A and from the auxiliary gas receiver or holder B through the retort 0 into the atmosphere. By then restoring the cap to the top of the retort and applying the spanning clamp o thereto with the keyway in engagement with the key of the valve 0" the valve will be operated to then permit of the flow of gas in the manner hereinbefore explained from the respective holders A and B through the connections from the retort C to the said members of the apparatus.

h is an ordinary gas-pressure gage located in connection with the gas-pipe from the retort C.

In operation the dome is caused to assume a position in the gasometer or holderA, with the vertical rod a in the position indicated in full lines in Fig. 1, and the double bellcranked levers F and F will then assume the position indicated in full lines in said figure and the connected valves f and f in the pipe connectionsfflf, and a will be automatically and simultaneously opened from the waterreservoir D and from the retort G to the gasometer or holder A, and the valve 7) in the pipe I) will be automatically and simultaneously closed from the retort C to the auxiliary gas receiver or holderl3. By the decomposition effected through the mixture or commingling of the water in drop form with the earbid or similar material will thus be given off a gas which will flow from the retort 0 through the pipe f and branch 6 thereof to the gasometer or holder A, rising therein through the water in a cool state and causing the dome or bell to to be elevated until the space between the water and the top of the dome is filled with the gas which is utilized therefrom through the pipe a and when the dome or bell a has assumed the position indicated in dotted lines in Fig. 1, with the ver tical rod a likewise in the position indicated in said dotted lines, the double bell-cranked levers F and F, with their connected curved arms having been caused to assume the position illustrated in said dotted lines, the water and gas valves of the pipes f and f will be closed and the valve Z) in the pipe I) will be opened to permit of the flow of gas through the said pipe into the upper portion of the auxiliary gas receiver or holder 13, whence it may be utilized therefrom through the pipe 0 located in the lower portion thereof.

It may be here remarked that the apparatus is so constructed that the gas generated in the retort C is supplied to either the gasometer or holder A or the auxiliary gas receiver or holder 13 in a cool state, thereby and desire to secure by Letters Patent, is

1. In a gas apparatus, a retort mounted in a tripod or standard, a hinged cap provided with a spanning clamp and connected with a valve located in a pipe connection from said retort with a holder, a gasometer provided with a dome, means connected with said dome v for controlling double bell-cranked levers opcrating valves of pipe connections from said retort with said gasometer, holder and a Water-reservoir, substantially as and for the purposes described.
