Title: Improvements in or relating to metal-drawing presses
IPC: B21D24/12
Filed: 1949-01-03
Abstract: 661,568. Cupping. STEVENS, A. H. (Clearing Machine Corporation). Jan. 3, 1949, No. 2584/49. Class 83 (iv). A cupping press includes two slides, one operatively connected to the middle portion of a maindrive shaft and the other coupled by linkages to two crossheads, each operatively connected to the main shaft and slidably mounted on a stationary rod adjacent the end of the shaft. The press frame comprises a bed 1 and crown 2 supported by side members 3 and 4, Fig. 1. Mounted in the crown is a crank-shaft 27 driven from a motor 14 by a belt 17 and gears 26. The outer work holding slide 7 is operated in guides 11 by adjustable connecting members 9 which move vertically through guides 10 and which are connected at their upper ends to links 39 which are pivoted at 44 to links 41 mounted on fixed pivots 42 and secured at their upper ends to links 37 pivoted at 38 to ears 36 extending from a crosshead 34 vertically slidable along two stationary guide rods 35. Pins 33 projecting laterally from the crosshead are received in an extension 32 of a strap 31 surrounding an eccentric projection 30 on one side of the gears 26 driving the shaft 27. The linkage is such that in the upper position of the crosshead shown in Fig. 6, the links 37 move through a dead-centre position without moving the slide 7, thus providing a comparatively long period of dwell during which the work is held and operated upon by the tool carried by the inner slide 8 which as shown in Fig. 5 is directly connected to the crank 28 of the shaft 27. In a modified form, Fig. 12, the crosshead is secured to the outer slide by a similar linkage but is arranged below the main shaft 59 from which it is operated by means of pins 63 engaging straps 61 around eccentrics 60 carried at the ends of the shaft. The shaft is driven by a pair of comparatively large gears 76 arranged between the eccentrics 60 and between the gears is a further eccentric 78 which operates the inner tool slide through a sleeve 80 with a downward extension 81 coupled by a pin 82 to a member 57 secured to the inner slide.

Title: Improvements in or relating to photographic easels
IPC: G03B27/62
Filed: 1947-01-29
Abstract: 624,130. Stands. PHOTOSTAT; Ltd., and DANIELS, A. Jan. 29, 1947, No. 2806. [Class 52 (iii)] [Also in Group XX] In an easel of the' kind in which a rectangular frame member with a glass plate and hinged clamping means, constituting a copy holder, is pivotally mounted on a stand to swing from a vertical position for copying to a horizontal position for manipulation of the copy, a supporting assembly for the copy holder includes a link pivoted at one end to the holder and slidable at the other end on an upright of the easel stand and carrying means at its slidable end which, as the holder approaches a horizontal plane, moves a locking plate on the stand to a position in which the plate prevents return movement of the link and is locked by a releasable latching device, said position corresponding to the horizontal position of the copy holder. As shown, the holder consists of a frame 1, Fig. 1, with a glass sheet 2, and a plate 3, preferably of aluminised metal, hinged to the frame and having conventional clamping means 3a, and may carry a fixed scale 27 and a movable scale 28 for positioning the copy. The frame 1 is pivoted in bearings 1a, at the upper ends of two vertical channel-section members 5, 5a forming part of a stand. Links 6, 6a pivoted at one end to one edge of the frame 1 at points on each side of the bearing 1a carry at their opposite ends pins 7 sliding in guide tracks 8, 8a provided in staggered relation on each side of the member 5. A rod 11, Fig. 3, mounted to slide vertically in blocks 10a, 10b, on the inner face of the member 5, has a plate 12 at its upper end and a wedgeshaped head 13 at its lower end. A circular locking plate 17 pivoted on the member 5, has on its edge diametrically opposite notches 18, a notch 19 midway between the notches 18 with rounded edges 18a, and a smaller recess 20 midway between one of the notches 18 and the notch 19. When the holder is swung on its pivots from the vertical to the horizontal position, the pins 7 slide from the upper and lower ends of the guides 8, 8a respectively until they engage the notches 18 in the locking plate 17 which rotates until the head 13 of the rod 11 drops into the notch 19 under the influence of a compression spring 14, locking the holder in the horizontal position. When a handle 26 is operated to rotate a rod 31 journalled in the member 5 and having finger member engaging the plate 12 to raise the rod 11 the locking plate is freed and the holder returns by spring action to its vertical position. The pins 7 rotate the locking plate until the head 13 of the rod 11 enters the notch 20. The return movement of the holder to its vertical position is damped by an air brake, and the pins 7 meet spring buffers 25 when the holder reaches its horizontal position.

Patent GB-1383143-A (GB)
Title: Remote control circuit breaker
IPC: H02H7/00
Filed: 1973-01-19
Abstract: 1383143 Protective arrangements CUTLER-HAMMER INTERNATIONAL FINANCE Inc 19 Jan 1973 [19 Jan 1972 (2)] 2973/73 Heading H2K [Also in Division H1] An overload protective device has main contacts 24 and overload trip contacts 33 resiliently biased towards their open positions, thermally responsive latching means 22, 66, 62 which close the contacts 33 when overload occurs, electromagnetic operating means comprising an armature movable between two limiting positions by energization of windings 26, 30, the armature being coupled to close the main contacts 24 by a member 58 which is released to open the main contacts 24 by the latching means. To closethe main contacts 24, a remote pilot circuitbreaker 4 is closed to turn off a transistor Q 1 to permit a silicon controlled rectifier 5 to conduct, so energizing a winding 26. The resulting flux overcomes that of a permanent magnet (not shown) and the armature 56 moves into the position of Fig. 2 where it is again retained by the magnet. This movement of the armature closes the main contacts 24, opens contacts 28 in series with the winding 26 and closes contacts 32 in series with the winding 30. If the circuitbreaker 4 is opened, the potential on a line 47 again rises so that the transistor Q1 is turned on and turns off a transistor Q3. This enables a capacitor C3 to charge and cause a silicon controlled rectifier 10 to conduct to energize the winding 30. This causes the armature to move back opening contacts 24, 32 and reclosing the contacts 28. In the event of overload, a bimetallic element 22 releases a latched member 62 which allows the member 58 to pivot on the armature 56 and open the main contacts 24. The member 62 closes the overload contacts 33 to cause current to flow through a resistor R8, a thermistor 34, a resistor R9, a diode D7 and a resistor R6. Initially this causes the transistor Q3 to be held on, clamping the control electrode of the rectifier 10 to earth. Then the circuitbreaker 4 trips open so that the current flow through the thermistor ceases and the voltages across resistors R8, R9 become equal causing the transistor Q3 to turn off. The controlled rectifier 10 conducts to energize the winding 30 to reset the armature and the latching means. Further devices 2, 3 may be connected as indicated for common operation in a three-phase circuit.
