EDWIN E. MILLER, OF ROCHESTER, MICHIGAN.

AGETYLENE-GAS GENERATOR.

To all whom it may concern:

Be it known that I, EDWIN E. MILLER, a

' citizen of the United. States, residing at Rochester, county of Oakland, State of Michigan, have invented a certain new and useful Improvement in Acetylene-Gas Gen erators, and declare the following to be a full, clear, and exact description ofthe same, such as will enable others skilled in the art to which it pertains to make. and use the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to acetylene gas generators.

It has for its object an improved device for feeding the carbid into the generating tank.

In the drawings :-Figure 1, is an eleva tion, partly in section, of the tanks. Fig. 2, is an elevation, partly in section, showing in detail the mouth of the carbid hopper. Fig. 3, is an enlarged detail of the sweep actuator.

1 is a generating tank, filled, or partially filled, with water.

4 is a cap at the upper end of the tank 1. At the apex of the cap 4 is a hopper-like receptacle 6, closed at its upper end by a movable cover 7 To feed the carbid properly into the generator, I make a carbid holder 6 funnel form, with a curved hanging bottom or receptacle 30, with openings or mouths 132, 133, through which the carbid is ejected by a shoe 131; this shoe is located above the upper surface of the bottom 30, and is connected to a sweep 31, which is pivotally connected to a swinging arm 32, pivoted within the generating tank and to the bottom end of the carbid hopper 6. The sweep 31 is pivoted to the end of the arm 32, to which is also pivoted a link 33 which at its lower end is connected to a link 34, which extends upward and emerges from the tank through a sleeve 134. The lower end of the sleeve 134 dips below the surfaceof the water in the generating tank. The sweep is provided with a shoe 131, and will be actuated to crowd a load of carbid off from the bottom 30, when the gasometer bell has fallen in consequence of the discharge of the gases contained therein. The projecting end of Specification of Letters Patent.

Serial No. 322,990.

the link 34 terminates with screw threads upon which are run two abutment pieces or arms 35 and 36, both of which are adjustable along the link, both with respect to the link 34 and to each other, providing means whereby the movement of the shoe 131 is adjustable to feed more or less carbid.

Upon the side of the outer shell 2 is secured a post or arm 37, upon which there is pivoted a lever 38 provided with rolls 39 and 40.

42 is a weight upon the outer end of a link 42, which latter is connected at the end opposite to the weight to the link 38, so as to be angularly adjustable relative thereto.

Upon the side of the gasometer-bell 20, adj acent to the post 37, is secured a curved finger 41, that normally reaches over the roll 40. As the gas escapes from the bell 20, and the bell 20 begins to fall, the curved finger 41 engages over the roll 40 on the lever 38 causing this end of the lever to swing into the curve of the fin ger, moving the weight 42 past the center of gravity, causing it to descend until the lever strikes the stop 45. In this movement the lower end of the lever with the roll 39 travels along the arm or abutment 36, and from there to the abutment 35, and lifts the link 34. The lifting of the link 34 swings the lever 32 and pulls sweep 31 and shoe 131 across the bottom 30, and forces the carbid through the opening 132. The carbid drops in the water and forms gas, and raises bell 20, and causes the lower part of the curved finger 41 to engage roll 40, raises the weight 42 past the center of gravity, and causes the roll 39 to reverse the movement of the abutment 35, link 34, lever 32, retracting sweep 31, and shoe 131, to point of beginning; at the same time another supply of carbid is pushed out of opening 133.

lVhat I claim is 1. An acetylene generating device, having a rising and falling bell, a generator having a carbid feeding device, a receptacle for the carbid, a sweep provided with a shoe adapted to feed the carbid, a link connected with sald sweep so as to actuate the same, movable arms upon said link whereby the movement of the same may be regulated, a curved finger adapted to be operated by the movement of the gas bell, and a weighted lever adapted to engage the arms upon said link and to be operated by said curved finger, substantially bell and Weight operates the feeding shoe,

as and for the purpose described. substantially as described. 10
