Title: Improvements in Pressing Apparatus.
IPC: B30B9/02
Filed: 1915-06-07
Abstract: 100,834. Marks, E. C. R., (Worthington, H. P.. [firm of]) June 7, 1915. Platen-presses.-Relates to filter-presses comprising platens mounted for relative angular movement, such as that described in Specification 14976/14, wherein the platens 1, 1<a>, Fig. 1, are connected by thrust members, for example arms 12, to fulcrum devices 13, 13<1>, in such manner that, as the platens move downwardly under the action of gravity, they also move towards each with an angular movement about. an axis in the vicinitv of their upper edges. The invention consists in the provision of means, actuated by fluid pressure, for adjusting the distance between the platens and thus obtaining the requisite pressure, the fluid-pressure device being arranged to vary either (1) the distance between the fulcrum devices, or (2) the length of the thrust members. (1) The fulcrum devices 13, 13', Fig. 1, are slidably mounted on pedestals 14 and are fitted with bolts 14a whereby they may be fixed in position. The fulcrum devices 13<1> are formed as ram cylinders in which are located rams 13<2> carried by cross-heads 13<4>. Tension rods 17 secured to the cross-heads pass through guide-openings in the fulcrum devices and are fitted with tubular sheaths 17<a> acting as stops. Pressure fluid is supplied by a pipe 64 branching from the pipe 26 supplying pressure fluid to the cylinder 20 used for opening the press as described in the above-mentioned Specification. The pipe 64 is fitted with a relief valve 68 to provide for the discharge of fluid if the pressure set up in the cylinder 13<1> in the operation of the press exceeds a predetermined maximum. (2) The thrust members, Fig. 3, are formed in two parts 12<b>, 12<c>, of which the part 12<b> constitutes a ram cylinder and the part 12<c> carries a ram. The pressure-fluid supply is controlled by a slide valve 76 pushed inwards by a spring 77. A trip rod 79 on the ram pushes the slide valve outwards. This arrangement provides for a considerable movement of the slide valve without shutting off the supply, and at the same time ensures the closure of the slide valve if the ram and the cylinder are separated unduly.
