Title: Improvements in or relating to hydraulic presses
IPC: B30B15/00
Filed: 1943-05-26
Abstract: 576,020. Shells, filling. STEVENS, A. H. (Denison Engineering Co.). May 26, 1943, No. 8430. [Class 9 (ii)] [Also in Group XXIX] A hydraulic press for compressing explosive in shells comprises a work-table rotated intermittently by a fluid-actuated motor, which tends to rotate it constantly in one direction, and fluid-actuated table-locking and releasing means. The shells are supported in spacedrelationship on the table 64, and are brought in pairs in succession beneath the press rams, the table being locked during the pressing operation. Pressure fluid supplied by a pump 13 passes through a main control valve 50 and supply line 59 to the small ends 60 of differential rams 68, thus effecting an approach stroke. At completion of this movement, high-pressure operation is initiated by a cam 98 carried by the rams, which actuates a valve 95 to admit pressure fluid to open a valve 103 and admit pressure to the large portions 67 of the rams. Thereafter pressure builds up in the supply line 59 and opens a valve 113, thereby actuating a pilot-valve 115 to reverse the main controlvalve 50, whereby the ram cylinders are connected to exhaust and pressure is applied to the retracting cylinder 121. At the upper limit of travel, the table-locking bolt is released by the pressure fluid which passes through a pipe 124 and valve 125 to move a valve 144 connected by linkage to the bolt. The table begins to rotate under influence of the liquid motor 164 and reverses the valve 125 by cam action to cause the valve 144 to return to table-locking position, and at the same time to admit pressure fluid to reverse the main-control pilot-valve 115 and initiate anew pressure stroke. A valve 185 in the connection between valves 144 and 115 may be set for continuous operation or to stop the press after a single cycle. If a shell is missing from the table, a safety-valve 187 opens to connect the pressure supply to exhaust and to release pressure on a relief-valve 17. A back-pressure is maintained in the retracting cylinder by a valve 206 during the pressing operation to ensure equal movement of the rams 68. Spring-loaded strippers 76, Fig. 10, are carried by the lower portions of the rams. Shell cases 92 are supported in cylindrical members 84 on the table 64.

Title: Improvements in or relating to machines organised for pressing breast flaps on shoe soles against heels
IPC: A43D25/12
Filed: 1939-03-20
Abstract: 528,040. Securing heel breast flaps. BRITISH UNITED SHOE MACHINERY CO., Ltd., BRAY, W. N., BARTON, F., and POTTER, S. W. March 20, 1939, No. 8752. [Class 17 (i)] In a machine for pressing a heel breast flap against a heel, the magnitude of power pressure applied may be controlled as the pressure is being applied to the work, being determined by the pressure applied to a manual control. The invention is described applied to the machine described in Specification 501,845. The lever 1 by which pressure is applied to the pads 3 is retained in operative position by pawls 13, which may be freed from their ratchet teeth 15 by a finger lever 35. The lever 1 is depressed by a handle 9 pivoted thereto and integral with an arm 37 carrying a roll 39 co-operating with a surface 153. An arm carrying a tooth 49 is pivoted to the handle and urged towards teeth on a slide 51 by a spring, a stop normally preventing contact. The slide is linked to a crank 75 actuated by power under control of a threearmed lever 125. One of the arms of the lever is urged clockwise by an adjustable spring 135 connected to a lever 143 on which is formed the surface 153. Another arm carries a stop 133. The third arm carries a roll 149 engaging a plate on the lever 143. The lever 125 is secured to a quick pitch screw 117 engaging a fixed sleeve 79 on which rotates a constantly driven chain sprocket 91 secured to a clutch element 85 normally separated from a driven clutch element 81 by a spring 121 abutting against a pin engaging the head of a screw engaging the screw 117. Rotating with the element 81 is the crank 75 linked to the slide 51. In operation, a workpiece having been positioned at the operator's station, the handle 9 of its clamp is depressed, the roll 39 causing the bell-crank lever 143 to turn clockwise as manual pressure is exerted on the clamps 3 by the lever 1. At the same time the tooth 49 engages the slide 51. As depression of the handle continues, the spring 135 turns the lever 125, the friction clutch is engaged and the slide 51 pulled down by power with a force dependent on that exerted by the operator on the handle 9. When sufficient pressure has been applied the handle is released, the lever 1 being held by the pawls 15. The clutch is disengaged by its spring, various other springs return the parts to starting position, and the turret can be rotated one step. To free the work at the next press, the handle 9 is depressed without pressing the lever 35. On release of the pawls 13 by power, the handle may be thrown up to release the work. In a modification, the spring 135 may be quickly adjusted by a cam having three recesses at different radii. Specifications 202,574, [Class 17 (i)], and 343,151 also are referred to.
