Whatever im-purity may be in the metals is thus worked out by the squeezer, atthe same time that the bloom is made perfectly solid and rotary squeezer is probably a much better machine for this pur-pose than any other now in use, inasmuch as it saves labor, and per-forms the work in a very brief space of time. The stationary part of. HOTART SQUEEZER. the apparatus is marked a a, and consists chiefly of a cast iron cloak,which encloses the movable parts, bbb. An eccentric space betweenthe two main parts is thus left, in which the ball is placed, and is thusrolled and pressed into a bloom by the time it comes out. The heatedball makes a rumbling noise in its passage through the rotary squeezer,accompanied with one or two very loud reports or explosions. Thesqueezer, however, is very compactly built, and is so constructed thatit cannot well be choked up or broken by too large a charge. The blooms are generally conveyed directly from the squeezer tothe roughing rollers, where they are thinned and considerably elon-gated. The engraving on page 127 represents a series of flat rollers, fromwhich the gradual transition of the metal in a round to a long and MANUFACTURE OF IRON 127
