The clay is tempered quite stiff, and charged into the machine from which it is forced in the form of a rectangular bar whose cross section has the same area as the greatest plane surface or end of the brick. The bar of clay as it issues from the machine is received on the cutting table, and is cut up into brick either by means of a series of parallel wires set in a frame which slides across the cutting table, in which case the machine stops when the bar has issued a certain length, or else the bar of clay issues continuously, and is out up by means of wires on a revolving frame. The former method is usually employed in connection with the plunger type of machine and the latter with the auger type. The plunger machine consists of a large iron cylinder into which the clay is charged, and from this it is forced out through the Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original New York State Museum; New York State Museum.
