To all whom itmay concern:

- Be it known thatI, MILLARD FrLLiuonn DERRICK,- a subject "of the; King of Great Britain'and Ireland and the Isle ofjMan, andresident of'Montreal, Canada, have in: vented new "and useful Improvements in Suction Ga's-lhoducers, ,of which the 'fol- This invention has reference to andcomprises improvements in suction gas, pro

ducers'in which the fuelis fed toja combustion chamber wherein the gas is generated, collected-and conveyed to the engine which is tobe operated thereby l The invention consists in the provision of a suction gas producer of the underfeed type characterized Yby' the fact that 'the whole of the fuel is continuously "and-Euniformly under compression forced from'the lower to the. upper end, of the combustion chamber by a helical conveyer extending the full diameter of said chamber-and oper-' ating'in a feed chamber situated directly below same. The ashes are disc'hargedf'over the top edge of the wall of the combustion chamber through water seals preferably "be-- ing guided to said seals and between the said combustion chamber wall and. an outer wall by angled plates.
