If it is desirable to increase the output of the press by a special design in the pump, it would be better to have three ot the plungers the same size and introduce a fourth one of larger diameter than the rest. As the three similar ones do the greater part of the work, they should be spaced 1200 apart, as in an ordinary triplex, and the extra and larger one midway between any two of them. The strain on the gear and belt will not be even at first, when the load is light, but occurs when the pressure is heavy, when the pump is working properly as a triplex. There may be objections to this, but when it is remem-. Balmg Room Arrangement of rro//By& n Bo///?y Press DryPv/p7ob/e LJ.
