JOHN WILLIAM PAINE AND CHARLES B. DOUDNA, OF BAYARD, IOWA.

ACETYLENE-GAS GENERATOR.

SPECIFICATION forming part of Letters Patent No. 642,478, dated January 30, I900.

Application filed February 2, 1899. Serial No. 704,224. (No model.)

To all whom it may concern-.-

Be it known that we, JOHN NVILLIAM PAINE and CHARLES B. DOUDNA, residing at Bayard, in the county of Guthrie and State of Iowa, have made certain new and useful Improvements in Acetylene-Gas Generators, of which the following is a specification.

Our invention is an improvement in what are generally known as acetylene-gas generators, and relates particularly to the means fordischargin g successively a series of charges of carbid into the water of the generator as well as the provision of means whereby the carbid is held a short distance below the surface of the water during the generating process.

The invention consists in certain novel constructions and combinations of parts, as will be hereinafter described, and pointed out in the claims.

In the drawings, Figure 1 is a perspective View of an apparatus embodying our invention. Fig. 2 is a vertical section of the generating apparatus. Fig. 3 is a cross-sectional view looking up on about line 3 3 of Fig. 2. Fig. 4: is a top plan view of the generator, and Figs. 5, 6, and 7 are detail views illustrating the escapement device.

The gasometer has a bell A, which rises and falls as the gas-supply is increased and decreased, as will be readily understood. This gasometer is connected with and receives the gas from the generator B. The generator B has an outer casing 0, having the sloped bottom 0 and the draw-oft valve C In the casing O is supported the stand D, which is open at its lower end and dips at such end in the water within the casing O. The stand D is closed at its top and is arranged to revolve within the casing, it being turned by the stress of a weight E, whose cord E is suitably guided and operates upon a pulley D, which is connected with the stand D. The stand D is journaled at its upperend in a cross-bar F, which is connected with the casing and extends above the top of the stand. This bar F is detachably connected at one or both ends, so that it can be adjusted to permit the removal of the stand.

WVithin the stand we provide a series of pockets or cups which are preferably arrangedin a circular series and have their bottoms arof the bottoms G are released. To secure the bottoms G we provide latches H, preferably in the form of turn-buttons, as shown in Fig. 3, which are pivoted between their ends, are arranged at their outer ends to lap under the inner edges of the bottoms and hold the same closed, and have their inner ends arranged to successively engage and be released by an abutment H, which is fixed with relation to the case 0 and is preferably secured to the stand-pipe 1, arranged within the generator, as shown in Fig. 2. The pipe I is braced in the generator by the inclined rods (shown in Fig. 2) and is provided between the generator and the gasometer with the U-shaped drip-pipe. (Shown in Fig. 2.) As the stand D is turned its pockets will be successively discharged by the contact of the buttons H with the abutment H. If the stand were free to revolve uninterruptedly by the action of the weight E, the several pockets would be discharged in quick succession one after the other; but it is our purpose to discharge the said pockets as needed, and to this end we control the movements of the stand by an especial form of escapement, which in turn is operated by the movements of the bell A of the gasometer. To this end we provide on the stand A a series of pins J, one for each of the pockets G, and we also provide the escapement-lever K, which is pivoted at K to the cross-bar F and is connected at one end by a suitably-guided cord L with the bell of the gasometer and is provided with the dogs 1 and 2 for engagement with the pins J of the stand D.

In operation when the parts are in the position shown in Fig. 1 one of the pins J will lie against the dog 2, as indicated in dotted lines, Fig. 7. If now the gas in the gasometer be consumed and the bell A lowered sufficiently to tilt the lever K to theangle shown in Fig. 6, the pin J, which rested against the dog 2, will be released and the stand D will be given a partial rotation until the next pin J strikes against the rear side of the dog 1, as shown in full lines, Figs. 7 and 6, and will be held until the bell A rises and permits the lever K to adjust to the position shown in Fig. 5, where the pin J will lie against the dog 2 until the operation before described is repeated. As each pin J is released in turn the stand D is given a partial rotation suflicient to secure the discharge of the contents of one of the cups into the water. Thus the supply of the generating material is controlled by the consumption of the gas in the gasometer.

Within the generator we provide a grate M, just below the normal water-line and in position to receive the carbid discharged by the tripping of the latches which hold the bottom of the pockets.

The gas enters the pipe I from the generator through a suitable opening near the upper end of the said pipe.

Having thus described our invention, what we claim, and desire to secure by Letters l atent is- 1: The combination of the revolving stand, having the projecting pins, the pivoted lever provided on opposite sides of its pivot with dogs moving alternately into the path of the pins, and pockets carried by said stand and arranged to discharge substantially as set forth.-

2. The combination of the generator-casing, the stand revolving therein and provided with the series of pockets to discharge their contents, the stand-pipe in the generator and supporting the stand at its upper end, and means for operating the stand and for controlling its movements substantially as set forth.
