To all'whom itmay concern: 1

Be it known that we, CHARLES T. TAR PENNING and OTTO SoHnLLnR'r, citizens of the'United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented certain new and. useful Improvements v in Acetylene-Gas Generators, of which the following is a specification. I Y 1 This invention relates to acetylene gas generators which are particularly applicable to be used for generating acetylene gas for lighting. purposes where artificial coal gas is not available. j i The object of the invention consists in the provision of a gas generator of the above character which includes a secondary carbid-receptacle for holding carbid independently of the carbid in the main receptacle, which'carbid will be automatically fed into the generating chamber at predetermined periods of time when the carbid in the main receptacle. is exhausted, so that the lights may be continued for a'greater length of time, and also indicating both that the reserved carbid is being drawn upon andthat the re-filling of the 'main carbid receptacle is-imperative. r I

A'further object of the invention consists in the provision of a gas generator of the above character wherein a high" grade of gas can be economically produced, the generator being automatically operated by the variation inthe volume of gas within the bell, until the carbid is entirelyexhausted. A further object of the invention consists in the provision of a gas generator of the above character embodying construction to reduce the liability of leakage of gas to a minimum, thereby preventingwasteof gas and possible loss of both life andprop erty through explosion.

Ne accomplish the above objects of the invention by means of the construction illustrated in the accompanying drawings, forming a part hereof, in wh1ch Figure 1 is aview partly inside elevation and partly in section of our improved acetylene gas generator. Fig. 2 'is a sectional view on theline 22 Fig. 1. Fig. 3 is a top or plan view of the generator. Fig. at is a top or plan viewof the carbidreceptacle, the other portions ofthe genera-- tor being omitted. Fig. 5 is 'a cross section on the line 5 5 in Fig. 4. 'Fig. 6 is a horizontal section on theline 6-6 in'Fig. 5.

F ig. 7 is a vertical section on the line 77 in Fig. 5.

Referring to the drawings, 10 represents the main generating chamber which is preferably formedas shown in Fig. 3 of the drawings. means of a horizontally disposed diaphragm 11 having .a vertically disposed throat-piece 12 through which the carbid passes from the carbid-receptacle to the water within the generating. chamber 10. 15represents the carbid-receptacle which is easily inserted'into the upper end of the throat-piece,.12,.the introduction of said receptacle 15 being limited byfmeans of a plurality of straps16. The floor 17 of the carbid-receptacle 15 has a cone-shaped formation, in the usual manner, so as to feed'the carbid to the center by gravity and throughjthedischarge opening 18. The flow of'thecarbid through the opening 18 is regulated by means of a valve 19 which is, attached to the lower end of the valverodf20 which extends vertically through the center of the carbid-receptacle 15. The upper end of the valve-rod 20 is engaged by standard 22, the free end of the lever sustaining a weight 23 which holdsthe valve The chamber is divided by means of a leverj21 which is pivotedina nearly exhaustedfrom thebell so that a new charge of carbid is discharged into the generating chamber to renew the supply of gas in the bell. In order-to prevent leakage of gas around the carbid-receptacle 15 the latter is entirely inclosed by means of a hood 25 the lower end of which is sealed by the water 26 above the diaphragm 11.

30' represents the gas holder or bell wherein the excess of gas is stored, the said bell being confined within the hollow shell 31, thebell being free to move vertically as the volume of gas is increased, as shown by means of the dotted position in Fig- 1. As the gas is withdrawn from the bell 30 the latter descends, and when it has almost reachedthe limit of its downward travel it actuates the lever 33 through the chain 34, the lever 33,

by means of the chain connection, being I unaffected by the upward travel of the bell 30. 'The lever 33 extends acrossthe top of the. hood 25 and is pivoted to the standard 36 at 37. Through this connection the hood 25 is; depressed when the lever 33 is acted upon by the bell 30 until said hood contacts co zw 1 with valve-rod 20 when the valve 19 is opened and a new charge of carbid is discharged into the generating chamber. As a new supply of gas is generated the gas passes out of the generator into the throatpiece 12 and thence into the outlet pipe 40, at which time suflicient pressure exists within the hood 25 to raise the latter sufficiently to clear the end of the valverod 20. As soon as the weight of the hood has been removed from the valve-rod 20 the valve 19 closes the opening 18 by means of the counterweight 23.

It will be noted that the valve-rod 20 is provided with'a second valve 42 which is situated upon said rod a short distance above the valve 19. The object of the valve 42 is to prevent, in case the valve rod 20 is pushed entirely down and remains so for any cause, the entire contents of the carbid receptacle being discharged through the discharge opening 18.

As before stated, the gas passes from the generating chamber through the pipe 40 into a chamber situated in the lower end of the shell 31, said chamber being divided by means of a horizontal floor 46 in the shell 81. The chamber in the lower portion of the shell is divided into two

compartments

17 and 48 by means of the vertical divislon wall 49. As the gas is discharged from the pipe 40 into the compartment 47 it contacts a baffle-plate 50 whereby the gas is forced downwardly around the lower edge of sa1d plate and through the water 51 where the impurities are removed from the gas. The gas in the compartment a7 passes upwardly through the pipe 55 arranged vertically within the bell 30 and discharges therein through a washer 56. The excess moisture in the gas is allowed to drain back down through the pipe 55 into the compartment 47. l Vhen the gas is being consumed the bell, which is being held in suspenslonby the buoyancy of the gas, descends forcing the gas to pass out through the plpe to the service pipe 65. WVe provide a loose connection between the ends of the

pipes

60 and 65, the upper end of the pipe 60 being enlarged as at 67 which is filled with suitable fluffy material to extract whatever moisture may be retained in the gas after passing through the washer 56. The adjacent end of the pipe is provided with an enlarged sleeve which fits down loosely over the enlargement 67 on the pipe 60, the lower end of the sleeve 70 being sealed by the water above the diaphragm 11.

Examining Fig. 3, it will be noted that access may be had to the generating chamber through an opening 7 5 through which the sludge may be removed and the cleaning of said chamber effected. The opening 7 5 is normally closed by means of a lid 76, and said lid is provided with a handle 77 which extends a considerable distance above the generating chamber. This enables the lid 7 6 to be easily removed from the top of the ground when the generator is let into a pit in the ground, which is the desirable way of construction, as it saves space, removes it from view and renders it less liable to be tampered with by unauthorized persons.

It has heretofore been mentioned that the generator is provided with certain means whereby a portion of the carbid is confined separately from the major portion, so that instead of allowing the lights to be extinguished without warning when the major portion of the carbid is exhausted, the small reserve supply can be drawn upon. As the reserve carbid is only released after the gas is almost entirely withdrawn from the bell, and with the resulting reduction in pressure of the gas at this time will show a corresponding reduction in the brilliancy of the lights, and as the increased illumination of the lights immediately takes place after additional gas is generated from the reserve carbid, it acts as a signal to indicate that the reserve carbid is now being drawn upon so that further consumption of gas can be controlled for the time being, and further indicating that the time for re-filling the main carbid-receptacle is near at hand. This is accomplished by means of a semi-circular gate 80 which divides the carbid-receptacle into two compartments. The gate 80 is pivoted at each end to the walls of the carbid receptacle 15 and is actuated, to allow the confined carbid to escape toward the dis charge opening 18, by means of the operating-rod 81 which extends vertically through the carbid-receptacle and pivotally engages the lever 82 which is pivotally supported in the standard'83. The free end of the lever 82 extends beneath the lever 21 and is actuated thereby when the lever 21 is sulficiently depressed to engage the lever 82. Ordinarily when the lever 21 is depressed by the valve-rod 20 to unseat the valve 19 the lever 82 is not affected, this occuring only when the gas is almost entirely withdrawn from the bell 30 and the latter descends to such an extent that the hood 25 forces the valve-rod 20 and lever down to a point until the lever 21 contacts and actuates the lever 82, whereby the gate 80 is raised through the rod 81.

Having thus fully described our said invention, what we desire to secure by Letters Patent, is

1. In an acetylene gas generator, the combination, with the generator casing, of a carbid holding receptacle arranged so as to discharge its contents into said casing, a gate arranged within said carbid holding receptacle for separating and constraining a portion of the carbid apart from the main mass, a rod connected to the gate and extending above the receptacle, said rod being actuated by an abnormal depression of the hood for elevating said gate and releasing the constrained carbid after the main mass of carbid is discharged.

2. In an acetylene gas generator, the combination, with the generator casing, of a carbid holding receptacle having a discharge opening arranged to discharge the carbid into said casing, a valve for controlling the flow of carbid through said discharge opening, a valve-stem for mounting said valve, a hood for inclosing said carbid receptacle and operating the valve-stem by the lowering of the hood, a gas holding bell communicating with said casing, means actuated by said gas bell for depressing the hood, a gate arranged within said carbid holding receptacle for separating and constraining V a portion of the carbid apart from the main mass within said receptacle, a rod connected to the gate and extending above the carbid holding receptacle, said rod being actuated CHARLES T.
