The top12 of the casingis-provi'ded with -a; central opening 27 about which is formed an upwardly directed, externally threaded bottoms. are covered with a coating (if-scrap iron. or'iron shavings25 whlch l S 1Il tur f plih'g' 30. .The toppositelarmfof this cross c'ouplingis normally closed by 'a' turn 'plng. 31L Extending into the/horizontal arms-32' coupling '35 havingtr ischarge dripinozzle iier eiids of Whichiar 36 which extends centrally of thezo' giemng 27 An oil'holcling tank 37 and an acid holtl ifig tank 38 iii-e, mounted upon the u per ti og-indudesa casing 10 whieh is pitejier endsfo'f pipes 3919\nd., flftlie lower en s of lead or other suitable matter as shown at 45' of-the pipe and through the top of the tank, I

as shown; These valves are normally held 2O in'lowe'red .or closed po-sitionby means of which are connected to the pipes 33 and 34, respectively, by elbows 41. Each of these pipes is provided with a sight glass 42 havmg a cutoff valve 43 and a drain cook 44 and the oil or acid, as the case may be, isecaused to pass through these sight glasses by filling that portion of the pipe 39 or between the .upper and lower ends of the sight glass with passage of the-liquids through coiled springs 52 which surround the. valve stems and bear between the valves and the spiders 51.

Anarm' 53 extends upwardly from the top. of each of the tanks and fulcrumed intermediate their length upon the upper ends of these arms are levers 54,. one end of each of which is operat'ively connected to the valve stems 50. The valve stems 19 are extended as shown in Fig 1, and operatively connected to the free 'ends of .the levers; thumb screws 54 being provided at the points of conn'ectionto regulate the throw of the levers. It will therefore be seen that upon drawing gas out of the generator, the partial vacuum formed therein will cause the valves 20 to open and admit air and. the

opening of certain of these valveswill act through their 'valve stems 19 to open the' valves 49 and admit a corresponding supply of oil and acid, the amount of which may be governed by the manually operated out off valve 43, the flow of oil and acid being gaged by the sight glasses 42. 1 The air inlet valves 20 may sometimes fail to admit suificient air. To meet this condi tion, I provide supplemental air inlet valves 20', shown in detail in Fig. 5, which fit against valve seats 21, formed; within short tubes 22. secured in the top l2. v The stem 23"of each of said valves is threaded and a thumb nut 24 issmounted on, said stem to bearupon a spider 26' and hold thej'valve normally locked to its seat while a spring 25 is coiled around the stem between the valve and the spider and tends to move the valve from its-seat. If the nut be loosened, the spring will expand and move the valve from its seat and thereby admit additional air. Secured to 'the inner face of the top 12 and'in spacedrel-a-tion about the opening 27 are L-shaped brackets 53 which support a drip pan 56 in posit-ion to receive the mixed oil and acid as they pass from the nozzle 36.

ach of the pipes 39 and 40 is- Secured to the lip ofthis pan in spaced relation and extending'radially therefrom, are a plurality of relatively heavy drip wires 57 and it will-beapparent that as the oil "and acid accumulate in the pan 56, they run over the lip of the pan and along these wires dropping off from thewires upon the cotton waste below; By this means, a comparatively uniform distribution of the oil and acidis obtained. This is a very important point in-the construction ofmy generator as. it is impossible to, obtain a spray feed withjthe small quantity of liquid supplied. In operation, the tank 38 is filled with any suitable acid, such as vinegar nd the tank 37 with any suitable gas oil. he valves 43 are then adjusted to give the proper s'upply of acid and oil to the generator. The acid.

and .oil pass throughthe pipes .34 and 33 re s'pectively,"and nozzle 36 and so to the pan 56-from which they pass along the wires 57 and drop, to the cotton waste '26 in the uppermost ofthe chambers. The gas, formed in the generatorcan pass freely through all parts thereof by the stand pipes 16 and also through thecforaminous partition walls 23 and said gas is drawn off from the generator through the pipe13 in any suitable manner.

As the generated gas is drawn off, the valves -20 in the stand pipes open automaticallyto permit the entrance of a fresh supply of air which, passing'through the stand pipes, is distributed uniformly throughout the generator. The opening of these valves also serves to open the. valves 49 and admit a proportional amount of acid and oil. The genera-- tion of the gas is therefore automatic and the gas obtained, providing the valves 43 are suitably adjusted, is uniform in quality.

, From the foregoing description, it will be apparent that I have provided an im 'roved form of generator which appears toe far superior to those nowin use, due to the provision of the automatic controlling of the acid and oil valves by the air intake valves, the uniform distribution of the mixed oil and acid over the topmost layer of cotton waste, and the free circulation of the sup- 'plied,air and of the generated gases through the entire generator as permitted by the perforated stand pipes and the foraminous partition walls. The stand pipes and partition wallsv are preferably enameled or otherwise coated to protect them from the action of the acid, but this is not essential as the action upon them will be relatively slight and they may be readily replaced when necessary.

It will of course be understood that I do 1 'not wish in any way, to limit myself to-the specific details of construction set forth in the above specification as anymodifications within the scope of the appended claims may be made, without inthe slightest degree departing .from the spirit of my invention.
