FRANKLIN EUGENE LAYTON, 0F CORNING, NEW YORK.

ACETYLENE-GAS GENERATOR.

SPECIFICATION forming part of Letters Patent No. 666.147, dated January 15, 1901.

Application filed J ly 10, 1899.

To all whom it may concern:

Be it known that I, FRANKLIN EUGENE LAY- TON, of Corning, in the county of Steuben and State of New York, have invented a new and Improved AcetyleneGenerating Apparatus, of which the following is a full, clear, and exact description.

My invention relates to certain improvements in the apparatus used for automatic generation of acetylene, and comprises cer tain novel features which will be hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a sectional elevation of my device. Fig. 2 is a sectional plan taken upon the line 2 2 in Fig. 1. Fig. 3 is a detail sectional elevation of the mechanism by which the trip-rod is raised. Fig. 4 is a plan view of the clutch-bar which engages the trip-rod to raise it; and Figs. 5 and 6 are respectively a sectional elevation and a bottom plan view of one of the carbid-holders.

My device belongs to that class of acetylene apparatus which uses the ordinary gasometer consisting of a water-tank and an inverted bell and a generator in connection therewith which employs a feeding apparatus. by which the carbid is discharged into a surplus of water in the generator in small quantities, as

desired. The gasometer consists of the water-tank A and the inverted bell B fitting within the same and rising and falling in correspondence with the amount of gas which is at the time stored. The tank A is provided with guide-bars A of the usual kind, extending upwardly therefrom and engaged by guide rollers or pulleys B, mounted upon the gasometer-bell B. The bottom A of the tank A has the central portion thereof sloping downwardly toward the center, forminga section of a cone, the object being that carbid discharged thereon shall slide by gravity to the apex of the cone, which is downwardly. This conical portion of the bottom, as herein shown, does not extend entirely to the outside edge of the tank, but this is immaterial, as said portion might as well extend entirely to the outside of the tank. At the apex of the cone a discharge-opening is provided,

Serial No. 723,322. No modelsthrough which the carbid will fall. Another cone D is secured to the bottom of the tank and extends upwardly into the water contained in the tank. The water-level of the tank is so located with reference to the cone D that the cone will be submerged at all times. Said cone forms the generating-chamber within which the gas is formed.

To the bottom of the generating-chamber is detachably secured a refuse receiving chamber F, which receives the lime formed by the decomposition of the carbid. The gas as generated in the chamber or cone D first comes in contact with the upper portion of the wall thereof, and any moisture which ma be contained therein is condensed on the side walls and then passes upwardly through a pipe which terminates in one or more goosenecks or depending sections d, the open ends of which extend beneath the surface of water in the tank. The gas passing from the generator to the gasometer is thus passed through water and is further cooled, besides having all particles of dust and foreign matter removed therefrom.

Through the center of the discharge-open-' ing connecting the generating chamber or cone D with the discharge-pipes d extends a rod or shaft G, which has a threaded section G at its upper end and screws into a block G which closes the upper end of the discharge-pipe. On the lower end of this shaft, which extends close to the bottom of the cone, is placed a valve G, which when forced downward is adapted to contact with a valve-seat f, formed about. the upper edge of the discharge-opening in the bottom of the generating-chamber. By this means the generatingchamber may be cut off from the refuse-receiving chamber F, so that the latter may be detached and cleaned and another or the same one replaced without permitting air to enter the generator or gasometeror interfering with the operation thereof.

The upper end G of the rod G is of some non-circular section which is adapted to be engaged by a socket-piece 9 upon the lower end of a rod g, which passes through a stuffing-box B located in the upper end of the gasometer-bell and in line with the shaft G, so that when the gasometer-bell has fallen to the proper distance the shaft g may be forced inward and into engagement with the upper end of the shaft G, so that the latter may be turned to force the valve G downward upon its seat. For convenience in turning the shaft g its upper end is made square or of some othernon-circularsection,as shown atg Placed within the refuse-receiving chamber F and surrounding the opening in the upper end thereof is a basket or box F, which is formed of perforated metal, wire screen, or any other suitable similar material which will catch and retain the carbid, but will permit the lime resulting from the decomposition thereof to pass through the openings and downward to the bottom of the chamber F. This keeps the carbid separate from the lime, so that its decomposition proceeds rapidly until it is entirely consumed. The carbid is introd need to the cone D or generating-chamber by means of an inclined spout E, which passes through the side wall of the tank A and enters the cone D near its bottom. The upper end of this chute entersa cup or small tank E, which is placed outside of the gasometer-tank and which is filled with oil, said oil floating upon the water contained in the generator and forming a layer of neutral liquid covering said water and acting upon the carbid to protect it until it has passed entirely within the generator, so that there is no generation of gas until the carbid has reached a point where the gas in rising will not pass outward through the feeding-chute. This device prevents premature generation of gas and the offensive odor which arises from its escape into the atmosphere.

The carbid is stored in separate charges in a number of holders H, which are contained within the chamber E placed upon one side of the tank A. One of these carbid-holders is shown in detail in Figs. 5 and 6, and consists of a small receptacle H of such a size as to hold an amount of carbid which will generate sufficient gas to substantially till the gasometer. The bottom H consists of a plate which is hinged at h to one side of the receptacle, so that when it is dropped the charge of carbid contained therein will be dropped into the generator. That part of the hinge carried by the bottom plate H is formed by cutting two slits inward from the edge of the plate at each side of its center and curving the portion contained between said slits about the pivot-wire, as is clearly shown at h, Figs. 5 and 6, where the same device is used to form a support for the catch-wire H which is thereby mounted to slide upon the body of the receptacle H in the bearings h. The ends of the wire forming the hinge-pivot are similarly supported from the bottom of one side of the holder. The catch-wire H is capable of being moved in its guiding-supports h, and has its ends it curved inwardly, so as to engage the outer corners of the bottom H, and thereby support the same. The central portion of this wire or that which lies alongside of the hinge is normally placed ata short distance outside of the hinge, where it may be engaged by .a trip-block, hereinafter described, and forced laterally until the hooks 72/2 are freed from the bottom H and the latter is permitted to drop, and thus to discharge the carbid. This catch device is operated by means of a trip-block J, supported upon the lower end of a vertical rod J, which extends alongside of the series of carbid holders. This rod is mounted to slide in suitable guides and is given a step-by-step upward movement by successive falls of the gasometer-bell. The block J is preferably mounted to slide within a guide J and the end or finger J which projects from the block and which directly engages the catch-wire H has its upper outer surface sloping, as clearly shown in Fig. 5, so as to act as a cam to force the catch-wire H laterally. A bar L, which is provided with teeth L upon one edge, is connected at its upper end by means of a horizontal section L with the upper end of the rod J. The bar L passes through aguidebracket M, fixedly supported upon a casing E which surrounds the carbid-holders, and the bar is maintained in its elevated position by means of a slide or catch m, mounted upon the bracket M, said slide being normally held projected by means of a spring m, which holds the outer end of the slide against the barL. As the barLis moved upward through the opening M in the bracket or arm M the catch m is forced backward until one of the teeth L passes above the same, when the catch is forced outwardly and will prevent the bar L from descending, if released. The bar L is elevated by means of a clutch device, (shown in detail in Figs. 3 and 4,) consisting of a bar or bolt K, provided with a central aperture 10 adapted to receive the rod J, and with a notch k in one end adapted to embrace the bar L. This plate is herein shown asv bent nearly in the form of a right angle, and the end opposite the notch k is provided with an aperture adapted to receive a cord N, which passes upwardly and about guide-pulleys N, supported on the framework of the gasometer, and thence downwardly, where it is attached to the gasometer-bell. As the gasometer-bell falls the bar K is raised.

In the position in which the device is shown in Fig. 3 if the bar K is allowed to drop it will descend until finally the notched end thereof falls below the tooth L located next beneath the one with which it is shown as engaged. Then if the bar K is raised by the descent ofthe gasometer-bell said bar will engage the tooth L next beneath the one with which it is shown in engagement, and its rise will thus'raise the bar L until the catch m may engage another one of the teeth L. The raising of the rod J and bar L is thus cumulative, they being raised a single step at a time, said step being the distance between two adjacent teeth L and being also the distance between two adjacent carbidholders H. It willbe noticed that the charges of carbid in the holders H, except for the bottom one, will be discharged through the holders beneath them. Thus the number of charges which may be used depends upon the height of the casing E and of theindividual holders H.

Should the gasometer become overcharged, the gas is drawn off from the gasometereither through an automatic relief service-pipe I of the usual character or through the overflow or relief pipe C. One end of the relief-pipe C extends upwardly within the gasometerbell and preferably within a small chamber formed by a plate which is secured to one side of the gasometerbell and curves inwardly. The upper end of this chamber is preferably provided with a screen of any convenient form, as shown in Fig. 2. The other end of this pipe enters the surplus or relief gasometer. This surplus or relief gasometer, located alongside the regular gasometer, is of the usual form, consisting of a tank a and an inverted hell 1), weighted so as to rise at a slightly-greater pressure than that of the bell B, so that the relief-gasometer will not be brought into use except after the hell B is filled. The guiding-framework surrounding the bell B is designed to form a stop which limits the rise of the bell, stopping the same at a point where its lower edge is at a sufficiently safe distance beneath the surface of the water in the tank. The gas will there fore not escape from beneath the lower edge of the bell unless the pressure is materially increased. As soon as the pressure rises above the normal the surplus or overflow gasometer bell b will be raised. Any excess of gas which may for any reason be generated will therefore instead of being discharged, pass into the overfiow-gasometer and be retained there until the pressure in the ordinary gasometer has been reduced to the normal, when the overflow-gasometer bell will fall, thus driving the gas back into the ordinary gasometer, from whence it is drawn and consumed.

A valve 0 is shown as placed in the pipe 0, by which communication may be cut off between the two gasometers. It is immaterial Whether the service-pipe be conducted into the ordinary gasometer or the overflowgasometer, as the gas may be drawn from either at will.

The refuse-receiving chamber F may be connected to the bottom of the generator-tank by any suitable means, either by a screwthreaded collar or by being clamped in place by any suitable device. It is herein shown as supported upon a plate or frame F which is in turn supported by means of chains F which at their upper ends are hooked upon the short ends of levers f, which are pivoted upon the posts A which support the gasometer in a raised position.

The service-pipe l, which leads to the burners, enters the gasometer at its. bottom and outside of the conical generating-chamber D.

Its upper end extends above the water-level in the tank and is provided with a screen-top 1 which is filled with a drying material-as animal charcoal, pumice-stone, or camphor through which the gas must pass, thus more perfectly drying the gas and preventing dust from entering the pipe and being thereby conducted to the burners. This pipe has a loop I, which forms a trap for the collection of water condensation. At the bottom of this loop is placed a drip-cock I which may be opened when desired to relieve the pipe of water.

The generating-cone D, it will be noticed, is only partially filled with water and is entirely submerged in the water in the gasometer-tank A. The upper portion of this cone therefore acts as a condenser to cool the gas and to condense any water-vapor which may be carried thereby. As a result of this, very little water will collect in the service-pipe, and there will be but little necessity for the drip-cock 1 It will be seen that the refuse may be readily removed from the generator without cut.- ting off the supply of gas and also that the carbid-holders may be refilled Without interfering with the operation of the ma chine. At the same time the water is not drawn off from the generating-chamber D, and there is no chance of airobtaining access to the gasometer or the generator, and thus forming an explosive mixture. This device is therefore both safe and convenient to operate.
