Title: An improved press for use in the treatment of cellulose sheets with alkaline lye
IPC: C08B1/12
Filed: 1936-04-09
Abstract: 473,547. Presses for separating liquids from solids. WEGELIN & HUBNER, MASCHINENFABRIK UND EISENGIESSEREI AKT.-GES. April 9, 1936, No. 10612. Convention date, April 11, 1935. [Class 46] A press for use in the treatment of cellulose sheets with alkaline lye is arranged in a container, one end wall of which serves as counterplate or abutment during the pressing operation and is movable in the direction in which the pressure is applied to facilitate the removal of the sheets from the press. The plates 5, Fig. 1, of the press are arranged vertically over a perforated false bottom 4 of the container 3 and the cellulose sheets are placed between the plates when the latter are opened out. On completion of the steeping process, the lye is drained from the container and the plates pressed together against the end wall 8 by the movable head 7 operated by a plunger 9. Surplus lye drains away through the plates 5, each of which comprises two perforated sheets with an intermediate sheet of metal netting. The end wall 8 is clamped in the closed position by wedge-shaped prongs 19, Fig. 3, which engage fixed rods 20 and inclined surfaces on the wall. The prongs are moved into and out of the clamping position by a manually operated worm 24 which engages a toothed sector on a rotatable centre-piece 17 to which the arms 18 of the prongs are pivoted. When the wall 8 is unclamped, it moves outward under pressure from the plunger on rails 12 drawing with it rails 32, 33, Fig. 6, on which the press plates move. As they are drawn out the rails 32 take up an inclined position, so that the press plates separate as they leave the container and allow the cellulose sheets to fall to a conveyer 15. The supply and discharge of pressure fluid for operating the plunger 9, and also a piston (not shown) which retracts the head 7, is controlled by a valve device 96, Fig. 13, operated by a lever 60. The lever is moved manually from the neutral position 65 to operative positions 64, 66 to start a movement of the head 7, but each movement is stopped automatically by engagement of a lever carried by the head against collars on the operating rod 54 of a slide valve 67 governing the supply of pressure fluid to the cylinder 57 of a piston connected by a link 59 to the lever 60. The plates 5 are arranged in groups of six, separated by thicker plates 6. The plates 6 are connected together by a Gall's chain 87, Fig. 19, and the adjacent plates of each group are connected by loops 94. The wall 8 is moved inward from the position shown in Fig. 6 by rods carrying a stop with which the head 7 engages in its backward movement. The outward movement of the wall follows engagement of the head 7 with pawls on the rods, which pawls are brought into operative position on withdrawal of the prongs 19 from their clamping position.

Electrode furnaces; resistance furnaces; heating by electricity.-An article, such as a tube to be tempered or annealed, is supported vertically and is automatically released so as to be discharged by gravity when it has expanded a predetermined amount. Simultaneously the current may be switched off. The tube &c. 11 may itself constitute the heating-resistance. It may be held by conductive clamps B, the lower of which is shown in elevation in Fig. 2 and in plan in Fig. 3. Each clamp comprises a casting having a rigid jaw 13 and a guide 16 for the stem 17 of a spring-pressed jaw 15. Both jaws are faced with laminated copper. The clamps are secured to a standard 7, vertical movement of the lower clamp being allowed by slots. A counterweight may be connected, by a cord passing over a pulley, to the lower clamp, so as normally to raise this. Both clamps are opened and closed by a shaft 26 made in two parts connected by an insulating sleeve 27 carrying an operating arm 28. The shaft 26 passes through eves on the stems 17 of the movable jaws and carries cams 31 bearing against the guides 16 on the castings. Each cam has two collars on opposite sides of the eye, the upper cam being rigidly secured on the shaft and the lower cam splined thereon. A cord 43 passes from the operating arm 28 over a pulley to a weight 41. Another cord 42 connects the weight to a lever 39 linked to a switch arm 38 in the heating circuit. A detent lever 44, engaging the lever 39 to hold the switch closed against the action of the weight 41, bears an adjusting screw 45 on which the lower clamp B impinges when the desired temperature is reached. Simultaneously with the opening of the switch, the clumps are disengaged by the weight 41. The tube falls into oil or other quenching liquid in a vessel 9 which, as shown, is inclined so that the tube rests against the side remote from the path of succeeding tubes. The tube 11 being heated is surrounded by a box C lined with heat-insulating material and opening on a vertical hinge 10.
