ACETYLENE-GAS-GENERATING APPARATUS.

Specification of Letters Patent.

Patented June 9, 1908.

Application filed October 27, 1904. Serial No. 230,278.

' generator, a rotatable feed plate located in said chamber to receive carbid from said hopper, and a carbid discharge wiper surmounting said rotatable plate and acting to direct the carbid therefrom when the plate is shifted in a forward direction.

Figure I is a view partly in elevation and partly in vertical section of a gas generating apparatus with my improvement incorporated therein. Fig. II is an enlarged section taken on inclined line IIII, Fig. I. Fig. III is an enlarged vertical section taken through the carbid receiving chamber beneath the hopper that surmounts it. Fig. IV is an enlarged vertical section taken on line IVIV, Fig. II.

1 designates a portion of a gasometer tank and 2 is a portion of a gasometer bell movably positioned in said tank.

3 is a guide rod supported by the gasometer tank and passing through a bracket 4 carried by the bell 2.

5 designates the upper portion of a generating tank that is surmounted by a carbid receiving chamber 6 having a lateral extension that is preferably disposed at an angle to a horipontal line taken through the generating tan 7 is a carbid hopper surmounting the chamber 6 and provided at its lower end with a neck 8 that extends into said chamber and is ppen at one side, as seen most clearly in Fig.

10 designates a rotatable feed plate located in the carbid receiving chamber 6 beneath the neck of the hopper 7 and extending to the upright portion 6 of said chamber to deliver carbid from said plate through said upright portion into the generating tank 5. The feed plate is preferably disposed at an angle to a horizontal line taken through the hopper neck surmounting it, as seen in Figs. I and III, and rotation is imparted thereto through the medium of a shaft 11 fixed to the plate and extending to the exterior of the chamber 6. This shaft is equipped with a pinion 12 that meshes with a pinion 13 carried by a suitably supported shaft on which is a ratchet wheel 14.

15 is a lever arm having one of its ends located alongside of the ratchet wheel 14 and bearing a pawl 16 that engages said ratchet wheel and acts to impart rotation to the shaft on which the ratchet wheel is mounted, from which similar motion is imparted to the shaft 11 and the rotatable feed plate through the medium of the intermeshing pinions 12 and 18. The free end of the lever 15 extends to the bracket 4 carried by the gasometer bell to be depressed by said bracket for the purpose of operating the lever to rotate the feed plate when the supply'of gas in the gasometer becomes depleted.

17 designates a wiper member that surmounts the rotatable feed plate 10 and is loosely fitted to the hopper neck 8 to which it is held by studs 9 projecting from said hopper neck and fitting loosely in slots 18 in said member to permit of a limited degree of rise and fall motion of said member. The wiper member 17 is formed with a forward and outwardly extending arm, a, and a rear and forwardly extending arm, I), that are spaced apart and roject from the separated vertical edges of the hopper neck 8. A passageway is thereby provided for the carbid that descends onto the feed plate through which the carbid passes to be discharged from said plate into the vertical portion of the receiving chamber 6 and fall into the generating tank 5. The wiper member 17 is provided at its bottom with diverging wings 19 (see Figs. II and IV). These wings rest directly upon the feed plate and serve to revent the passage of carbid between said p ate and the bot tom of the wiper member.

In the practical use of my apparatus, the operation is as follows: WVhen the bell of the gasometer associated with the generator equipped with my improvement descends, due to the depletion of gas in the gasometer, the rotatable feed plate 10 is rotated in a manner previously described. l/Vhen this rotation takes lace the carbid that has descended onto t e feed plate and is confined within the open hopper neck 8 and between the arms of the wiper member 17 is carried in a forward direction between said wiper arms. This quantity of carbid is thereby forced against the forward wiper arm, a, and as said wiper arm prevents continued forward carriage of the carbid on the feed plate, the carbid is caused to travel toward the edge portion of the feed plate overhanging the vertical portion of the carbid receiving chamber 6 and is precipitated over said edge to fall into the generating tank 5. The rotation of the feed plate is continued through the actuation of the mechanism connected thereto until sufiicient carbid has been delivered into the generating tank to" create a volume of gas that will, u on entering the gasometer, elevate the be 1 2 when the rotation of the feed plate will be discontinued until the supply of gas in the gasometer is again depleted subsequent to which the same action takes place as before.

I claim as my invention:

1. In an acetylene gas generating apparatus, the combination with a generating tank and a carbid holder provided at its lower end with a neck having an opening in its side, of a rotatable flat feed plate located beneath said holder neck and upwardly inclined from the solid part of the neck to the opening in the neck.

2. In an acetylene gas generating apparatus, the combination with a generating tank and. a carbid holder provided at its lower end with a neck having an opening in its side, of a rotatable feed plate located beneath said holder neck, and a wiper embracing the solid part of the holder neck and having arms extending beyond the opening in the neck; said feed plate being upwardly inclined from the solid part of the neck to the'opening in the.

fitted to said holder neck and having arms extending beyond the 0 ening in the holder neck; each of said arms eing provided at its bottom with diverging wings resting upon the feed plate.

4. A feeding mechanism comprising a hopper, an inclined rotary flat disk receiving the material from the hopper on its lower half, and a wiper surrounding the lower end of the hopper and having a pair of arms spaced apart to provide a passageway extending tothe highest 'portion of the disk and a discharge opening at the highest portion of the disk.
