It also puts the material in a conven-ient form for handling. The press is of the four-rod invert-ed cylinder type and is built in three different sizes and. Metal Briquetting Press pressure capacities, viz., 1,000 tons, 750 tons and 300 illustration shows the 1,000-ton press. The briquet forming mechanism of these presses has beenpatented in the United States and Canada, as well as in sev-eral foreign countries. It is capable of forming a briquetquickly and of uniform density. This is accomplished byplacing the material in a floating mold which is supportedby four springs; when the pressure is applied upon the ma-terial from above the friction of the material on the sidesof the mold causes it to move down over a stationary plungerwhich projects into the mold from below. Pressure is thusapplied on the bottom as well as on the top of the materialand its density is made uniform. After being formed, thebriquet is ejected from the moid by applying the pressureof the main ram upon the briquet, the lower plunger beingremoved by the movement of a controlling lever. The largepress is provided with a surge ta
