THE CANADA LUMBERMAN September, 1902 WOOD PULP ->© ®~ DEPARTMENT I NEW WOOD PULP PRESS. Mr. Joseph Stuart Hughes, of New Germany, Nova Scotia, has been granted a patent for a wood pulp press, as shown in the accompanying illustration. The claim is as follows : The object of this invention is a machine having con- fined spaces into which the fluid pulp can be run inter- mittently and 1 he water and air pressed out automati- cally, so as to leave a solid sheet of pulp in each space, a machine that can be handled with ease and facility and will do the work rapidly and with as little hand- labour as possible. With this object in view the improved machine is made double-ended and double-acting, the pulp is forced under pressure, special facilities are provided for the escape of water and air, and special facilities for loosening the pressed sheets in the press after pressing prior to their removal. The machine operates as follows : Assuming the. New Pulp Wood Press. chamber at the left hand of figure 1 to be empty, the inner bottom A3 lifted up tight, the door A4 closed, the nozzle A5 connected to the delivery pipes of a force pump supplying the fluid pulp, the drain pipes, F, F1, F11, connected with a suction-pipe, and the valves E open, as shown, the spaces 2 are being filled with the fluid pump under pressure. Immediately upon the entrance of the latter, and owing to the pressure on one side and the suction within the strainers on the other, water and air commence to be abstracted from it at once. When the spaces 2 are full of pulp, the valves E are closed by turning the wheel E3. Pressure is allowed to act on the averted face of the piston D, and it moves, pushing the plunger D1 in the chamber now under consideration toward the head. The pressure thus exerted upon the pulp within the spaces 2 causes the water and air therein to pas
