If'the device is to he used as it suction gus producer, the air may he drawn through the pipe 32 for consumption, as for starting :in engine; or if the device is to he used as appressure producer, compressed air muy he 1'5 suppliedby pipe 33.' The wnste ashes may hereuim'ed at: any convenient point adjacent the writer seul l5 in n. manner generally known. In the event that the device is to be used :is a suction gus producer this witter seul will admit the steam supply for the producer, und the ashes and cinders which will be heated to incnndes cence'will dropinto the. water, thus vaporizing purts oi it, und the vapor will he permitted to poss upwardly through the fuel, thus improving the gus und avoiding the necessity of utilizing it staun hoiler or vaporizer.

ln Figure 2 I have illustrated :i modiliention ol' the lower end of the producer, using gratos l5" instead ot the water seulA In this construction the openinpy l will be utilized as the nir supply, 45 :is n waste gas pipo, through which the gas may escupe, and 52 an air and steam supply. 53 und 54 indieate opent-nes through whieh instruments may be inserted for elesiniutr the producer, which openings muy he closed hy suitable doors 55 designates poke holes in one of the'elenuingr doors. These poke holes muy he arranged ut :my suitable point. the idea. being to have the poke holes arranged s0 that the pokers muy he moved bueh und tort-h in horizontal planes at any pluee in the producer. These small openings in the larger doors itlso serve :is sight openings, so that the workingr of the products in the producer may he observed from the outside. lliis urmngeiuent is rather important in that it. rednres tho liability oi accident, for, should the attend-.int desire to I open one of the. larger doors he might firstopen the smaller door so that in case au explosion is takin;r platee the products would not be blown through the door opening and the liability of injury to the attend-.uit would be reduced.

ln Figure 3 l have illustrated another form ol' the lower end of 'the producer, in which all ashes und elinkers are packed downwardly in the hopper und :ire perrnitted to rest'on a. closing device 56 ofeuy desired description. lu Figure 3 the same slide gate 55 is shown :is is illustrted tin Figure l. Below this elosintT device 56 is a Vessel 57 which is closed ou its lower end hy suitable means 58. The elosiufr means may be simply u full door or a gate valve. The ashes will be permitted to fall in u small enr 59 so that they may he carried to :t suitable premises and dumped. The operation of this devine is as follows: v

In euse a( down-draft it is not desired that the producer get air in thelowerend; t.herefore, the device 57' is open und the ashes are packed down in the vessel 5S. Afterward the vessel 57 is closed und the. device 58 is opened without any doneer of the entering ol uueontrolled nir or escaping gus. 'lhe controlled quantities of air, steiun. etc., rusty he allowed to enter through the pipe 'IH und*4 openings 7, und the poking hole 8 muy be llli used as diselosed in Figure l.

.\ltl`\ongh I liiive shown -the det-.nils of my improved gus produoer in the/forms liest known to lne nt thistiine, l would huye it understood that I do not liinitniysel to the erntet. detitils oi construction hut reserve the right to utilize sueh changes in form, proportion :ind-minor deteils ot' construction as muy suggestthemeelyesrmn t time to time and`con1e within the scope ofthe appended In such claims :is I have defined the geschamber as 'a het gas elianiber I have reference to a. reservoir'or' c'hmf ber in which the gus is relatively hot and in eoutralds# ,130
