SPECIFICATION forming part of Letters Patent No. 620,394, dated February 28, 1899.

Application'filed November 8, 1897. Serial No. 657,855. (No model.)

To all whom it may concern:

Be it known that I, BENJAMIN F. WILLIAMS, residing at Quanah, in the county of Hardeman and State of Texas, have invented a new and useful Generator for Acetylene Gas, of which the following is a specification.

This invention relates to generators for acetylene gas; and it consists incertain im provements upon the construction described and illustrated in my United States Patent No. 593,628, dated November 16, 1897.

One object of the present invention is to conduct the gas from the generating-chamber to the gasometer in a dry condition and return the condensations therefrom to the gencrating-chamber.

Another object of the invention is to provide a removable receptacle or catch-pan for the purpose of receiving the precipitated carbid and also for equalizing the weight upon the gasometer.

A further object is to provide a means for regulating the amount of pressure within the generating-chamber in addition to the device used in my former construction, thus rendering the generator absolutely safe at all times, as the surplus gas is conducted from the generating-chambers and explosions prevented.

Another object is to provide an improved means for raising and lowering the carbidholder-supporting rods, so as to insert or withdraw the carbid from the water.

A still further object is to so construct the generator that access may be readily had to the various parts of the apparatus for cleaning or removing the same.

With these various objects in View my invention consists, essentially, of a generatingchamber and a gasometer, said generatingchamber having a coil of pipe therein, which is provided with a T-outlet, the upper end of which is in communication with the gasometer and the lower end depending beneath the surface of the Water in the chamber, so that as the gas passes through said coil the moisture is removed therefrom and conducted back to the water in the generating-chamber, while the dry gas enters the gasometer.

The invention consists also in providing an external pipe which enters the generatingchamber and communicates therewith at a point below the surface of the water and above the end of the T-outlet of the coil, said pipe havinga receptacle or casing placed therein at any desired height, according to the amount of pressure desired in the generating-chamber, so that when the pressure ex ceeds the predetermined amount the water will be forced upward into said casing until the gas is permitted to escape through said pipe and out of the building, and thus an additional device provided for the generator.

The invention consists also in providing a sectional top for the generating-chamber, the

outer section having the overflow-tubes se-. cured thereto, so that when said section is removed the tubes are withdrawn, and also in providing improved securing devices for uniting the sections of the top and securing the same to the chamber.

The invention consists also in providing supporting-rods movable in the overflowtubes, said rods removably supporting the carbid-basket and the catch-pan for receiving the precipitated car-bid, which may be withdrawn by removing the inner section of the top for the generating-chamber, said supports being connected with the gasometer, as in my former construction.

The invention consists also in certain other details of construction and novel combinations, all which will be fully described hereinafter and pointed out in the claims. I

In the drawings forming part of this specification, Figure l is a perspective view showing the generator and gasometer connected. Fig. 2 is avertical longitudinal section of the same. Fig. 3 is .a section on line 3 3 of Fig. 2. Fig. 4 is a section on line 4 4 of Fig. 2. Fig. 5 is a detail sectional view of a portion of the meeting edges of the chamberand sectional top, showing one of the securing-bolts for uniting the same. gitudinal section of the generating-chamber. Fig. 7 is a plan view of the inner section of the top. Fig. 8 is a detail view of the upper end of one of the carbid-basket supports, showing the connection of the upper cross bar thereto-and also showing the hand-nut for effecting the movement of the support.

Referring to the accompanying drawings, A is the generating-chamber, constructed, preferably, of metal, as in my former con.- struction, closed at its bottom and provided Fig. 6 is a vertical 1on Too at its top with a flange B and the slotted lugs B, in which the swinging securing-bolts B are pivoted.

The top for the generator consists of the outer section or rim 0 and the inner section or lid 0. Rim 0 is provided with the slotted lugs C around its edge, which are adapted to register with the slotted lugs B and receive the bolts 13 when the latter are swung upwardly, so that when the thumb-nuts B are adjusted upon the bolts the rim is clamped tightly upon the upper end of the chamber.

Lid or section 0 is united to the rim or section 0 in a similar manner, the former having the slotted lugs C to receive the swinging bolts 0 which are pivoted in the slotted lugs C formed upon the upper edge of the latter.

Overflow-pipes D pass downward through rim 0, in which they are secured on opposite sides of its center, said pipes depending beneath the surface of the Water in the generator when the latter is half-filled, so that the lower ends of the pipes are sealed.

A catch basin or receptacle E is mounted upon the upper ends of the pipes D, with which said pipes communicate through outlets F.

G are rods screw-threaded at their upper ends and movable in the pipes D, said rods being connected at their upper and lower ends, respectively, by the cross-bars H and I. Upon the upper screw-threaded end of each rod is an adjusting handnut J, which is adapted to rest upon the upper end of the pipe D. It will be readily understood that as these adjusting-nuts are rotated the rods are raised or lowered. Stop-nuts K upon the rods regulate the adjustment of the nuts J.

Projecting upwardly from the, center of cross-bar I is a post I, and adapted to be positioned upon the cross-barI by means of said post is the catch pan or receptacle L, which is provided with the central tube or socket L to fit over the post. This catch-pan receives the precipitated carbid, which is thus readily removed by withdrawing the pan.

M is a wire basket which contains the carbid, said basket having a cross-bar M secured to its bottom, which bar is perforated to receive the end of post I. A flange M is secured around the upper end of tube or socket L, upon which the basket rests.

N is a cover which entirely surrounds the top and sides of the basket and is of such size as to leave a space between its walls and the walls of said basket. Spring-catches N are carried by the cover for engaging the projecting ends of cross-bar M for the purpose of uniting the cover to the basket, so that the latter may be withdrawn from the generatingchamber by the former, which is provided with a handle for that purpose. Said cover is formed with openings N to permit the gas to escape therefrom.

O is a coiled pipe positioned within the generating-chamber, the upper open end thereof being adjacent the upper end of the chamber and the lower end communicating with a vertical pipe P, so as to form a T-outlet. The lower end of pipe P depends beneath the surface of the water in the chamber and is thus sealed, while the upper end projects through rim 0 and is connected with the gasometer. This coil Iterm the drying-pipe, as the gas is dried as it passes therethrough. By having a T-outlet for said coil the condensations pass downward through the lower portion thereof to the water in the chamber, while the gas escapes through the upper portion to the gasometer.

The gasometer is of the ordinary construction, consisting of the telescopic tanks Q and R, the lower tank B being filled with water and having the inlet and outlet pipes S and T, respectively, the former being connected with the outlet-pipe of the coil and the latter communicating with the gas-burner, suitable stop-cocks controllin g the communications therebetween.

A horizontal arm V is secured to tank Q, and from the extremity of this arm depends a chain WV, which is attached to the center of cross-bar H.

X is a safety-pipe which at its lower end extends within the generating-chamber and communicates therewith at a point below the surface of the water and above the lower end of the T-outlet of coil 0. Located in this pipe X at any desired height, according to the amount of pressure desired within the generator, is a receptacle Y. When the pressure in the generator exceeds the predetermined amount, the Water is forced out through pipe X into receptacle Y, where it spreads out until the water is forced down in the generator sufficiently to permit the excess gas to escape through pipe X, up through the water in receptacle Y, and out of the building. Thus a safety device is arranged in addition to overflow-pipes D, through which the water is forced by any surplus gas and into the catch-pan, said return returning to the chamber when the pressure is removed.

In operation the apparatus is set up as illustrated in Figs. 1 and 2, the carbid-basket be- .ing elevated from contact with the water in the generating-chamber. W'hen it is desired to generate the gas, the hand-nuts are revolved until the rods G are lowered sufiiciently to bring the carbid in contact with the water, when the gas will be evolved. The gas passes through the coil to the gasometer, the moisture removed therefrom during its passage through the coil passing downward to the water in the chamber. The carbid-basket is lowered the proper distance in the water, which can be seen from glass sights provided for the generator, as will appear from the drawings. When the gasometer is filled with the gas, the upward movement of tank Q will withdraw the carbid-basket from the water through the medium of the connection between the horizontal arm and the basket-supwithdrawn for any purpose, so that access is thus readily obtained to the interior of the generator.

Having thus fully described my invention, what I- claim as new, and desire to secure by Letters Patent ot' the United States, is

I 1. Inagas-generator,thecombination therewith of a coiled pipe located entirely within the generating-chamber, the upper end of said pipe opening into the gas-space, and the lower end being provided with a T- outlet vertically located, the upper end leading out of the chamber to con vey the gas therefrom, and the lower end being immersed in the water in the chamber whereby water of condensation is discharged from the pipe into the water in the chamber, substantially as described.

.2. In a gas-generator, the combination of a chamber, tubes leading therefrom, rods movable in said tubes, a cross-piece connecting said rods, a post carried by said cross-piece, a pan having a socket fitting over said post, a carbid-holder fitting upon said post and resting on the socket, and means for adjusting the rods, substantially as described.

3. In a gas-generator, the combination of a chamber, a sectional top for the same, tubes carried by one of said sections and projecting from the chamber, rods movable in said tubes, a carbid-holder removably supported by said rods and adapted to be withdrawn from the chamber by removing the inner section-of the top, and means for adjusting said rods, substantially as described.
