Malcolm's invention relates "to that class of gas-generators in which a fluid is used for making the gas, and consists of a cylinder, revolving longitudinally on trunnions, and divided into three departments. The fluid being poured into the uppermost department, runs, by a pipe, into the lowest one, forcing the gas that accumulated into the middle department, and thence out, through a conducting-pipe, for use."
