Abstract: 1491237 Stamping SAAB-SCANIA AB 4 Dec 1974 [5 Dec 1973] 52346/74 Heading B3Q In a press in which sheet metal 3 is formed against fluid pressure by at least one die or punch 35 and a blank holder 38 is mounted on at least one outer piston 26, both an hydraulic unit 19 including the pistons 26, 31, and a further piston 6 closing the end of the forming chamber 15 opposite the diaphragm are fixed to the pressframe 1, valve means 47 allowing the discharge of fluid at a controlled pressure from chamber 30 behind piston 26 and controlling the supply of fluid to chamber 34 behind piston 31, or allowing discharge from chamber 34 and controlling the supply to chamber 30 when part 35 is a die. With the pistons 26, 31 nested as shown on the left in Fig. 1 the press is closed by introducing fluid into chamber 30 so as to raise the pistons and carry the blank holder 38 against the work. Forming is effected by supplying fluid to chamber 34 for raising the inner piston alone. The constant volume of fluid in the forming chamber 15 now causes the chamber to descend over the rising punch, thus depressing the outer piston 26 over the rising inner piston 31. A control cam 56 is connected to the piston 31 and adjusts a potentiometer 58 connected to an amplifier 59 which is connected to an electromagnet in one of the valves 47 for setting the regulation pressure of the valve. This pressure regulates the other valve 47 which is connected to the chamber 30 for limiting the pressure therein primarily by causing the fluid from chamber 30 to flow to chamber 34, although it may be discharged to the tank 48. Retraction of the pistons 26, 31 is by a low-pressure pump connected, through a valve 50, to chambers 40, 41. In another form, Fig. 2, additional hydraulic jacks 70 are provided for opening and closing operations. The inner and outer pistons may be in separate cylinders and a plurality of outer cylinders may be provided, as in Specification 1,280,196 to which reference is made. When part 35 is a die the press is closed by supplying oil behind the inner piston 31 which entrains the outer piston through shoulder 67. The free end of the die is now substantially at the level of the holder 38. Forming is effected by supplying oil to the outer piston which rises thus depressing the die and inner piston.

Filed: 1976-12-23
Abstract: 1527790 Combination locks FICHETBAUCHE 23 Dec 1976 [31 Dec 1975] 53854/76 Heading E2A A combination lock is operated by rotation of two knobs (not shown), an outer one operating tubular shaft 23 and an inner one turning concentric shaft 90. The inner knob, via shaft 90, cog 561 and hence cog 559, which in turn rotates cylinder 330 having flat-bottomed grooves with the bottoms at 72‹ to each other. In each groove is mounted a finger plate 331 bearing a finger (not shown) engageable in a slot in a toothed wheel 231. The inner knob has five set positions, each of which corresponds to a point where one finger only is moved into its slot by the correct orientation of the appropriate groove on cylinder 330. In Fig. 17 cog 231 1  only is so engaged. Rotation of the outer knob turns, via shaft 23, a cage 312 in which is mounted the cylinder 330 and hence the finger plates 331. This causes the engaged wheel 231 to rotate and so to relate the corresponding wheel 261 meshed with it. By successive selection of positions of the inner knob, and so of cylinder 330, each wheel 261 may be set to the correct position, in which grooves in their peripheries are aligned. At this point the knobs are set to rotate wheel 261 0 , which has no groove but which bears a partially circumferential flange 154. This flange is rotated to the point where it no longer holds fence 900 out of engagement with wheels 261, whereupon it is pulled into the aligned peripheral grooves by the rotation of the linked drum 169, rotated by wheel 261 0  via a frictional coupling (not shown). Fence 900 supports a fence plate 590 to which is attached a flange 596. When this flange is depressed by the entry of fence 900 into the aligned grooves, the latch may be operated. Latch operation. As shown in Fig. 63, depression of flange 596 permits, by the movement of studs 598, 599 on the flange to the positions shown in dotted lines, a hook 610 and a pawl 632 to move. Hook 632 is now in a position where it can engage a stud 569 provided on wheel 563 which is keyed to shaft 90. Rotation of this shaft pulls the hook and hence moves latch 621 to an opening position. Pawl 632 no longer prevents this motion. Combination change. The combination may be changed when the lock is accessible by rotation of cam 283. This disengages wheels 261 from wheels 231, so that they may be moved to different relative positions.
