Title: Improvements in or relating to overload released electric switches, motor starters and the like
IPC: H01H73/04
Filed: 1953-10-15
Abstract: 761,564. Automatic circuit breakers. IGRANIC ELECTRIC CO., Ltd. Oct. 15, 1953 [Oct. 18, 1952], No. 28495/53. Class 38(5) A starter switch for a three-phase motor comprises one pair of fixed contact assemblies 24, 26 for each outer phase and a pair 24, 32 for the centre phase, the heater coils 38 of thermal overload devices of the selfsoldering type being connected in each outer phase between terminals which hold the lower contacts 26 in place and load terminals. The upper contacts 24 are held in place by line terminals 14, the upper centre phase contact 24 being also held in place by a line terminal 14 while the lower contact 32 is connected to, and held in place by, load terminal 16. When the switch is closed, each pair of fixed contacts is bridged by spring-urged contact assembly 100 mounted in notches 98 in a plate 96 projecting from the front wall 94 of a contact carrier 92 which also has side walls 110 and rear wall 112, and arcing shields 104 are provided between contact pairs (Fig. 6). The contact operating assembly comprises a frame 46 to which is pivoted a handle 52 by pin 54 held in place by the casing walls, the handle being pivoted to a link 56 by a pin 58, the link being pivoted to a latch 60 by a pin 62, and a tongue 66 on the latch engaging in a groove 108 on a projection 106 of carrier 92. A spring 68 biases the latch towards carrier 92. The latch pin 62 moves in carrying slots 64 in the frame 46 and when the handle is moved from the ON (Fig. 2) to the OFF position, the pin moves down the slots moving the latch and contact carrier backwards and thus disengaging the contacts. The overload mechanism comprises two levers 70 pivoted to frame 46 by pin 72, projections 76 on the lever anchoring contact carrier biasing springs 78. The levers have pawls 80 engaging the corresponding ratchets 40 and are recessed to accommodate latch pin 62 which bears against faces 82. When overload occurs, one or both coils 38 heat up thus releasing the ratchet and allowing the lever 70 to swing, a pin 84 on the lever (Fig. 6) hitting the latch 60 and thus causing the tongue 66 to disengage from the carrier which then springs backwards under the influence of springs 78 to disengage the contacts. To reset the switch, the handle 52 is first swung to OFF thus forcing pin 62 downwards in slots 64, and due to engagement of pin 62 with surfaces 82 of levers 70 the latter are swung to the position shown in Fig. 2. Also the pawls reengage the ratchets 40 and hold levers 70, and tongue 66 re-engages groove 108 as carrier 92 is prevented from rearward movement by a vertical part of contact 32. The handle 52 is then restored to the Fig, 2 position, whereby the cam slots acting through the pin 62 and latch 60 move the carrier 92 back to the ON position.

Title: Embossing machine
IPC: B41J3/38
Filed: 1936-10-20
Abstract: 470,144. Embossing - - machines. ADDRESSOGRAPH - MULTIGRAPH CORPORATION. Oct. 20, 1936, No. 28553. Convention date, Nov. 13, 1935. [Class 100 (iv)] Type-wheel machines for embossing metal; case-shift mechanism; shift-key actions.-The revolving die-head of a, keyboard embossing- machine of the kind employed for making printing-plates is provided with two interspersed sets of dies, for instance upper-case and lower-case, which are arranged in a single circumferential row and are associated with means for selecting either set without stopping the die-head. The die-head 25 shown in Fig. 8, is provided with upper and lower sets of sliding dies 26, 27, each set being arranged in a single circumferential row with lower-case and upper-case dies alternating. The die-head is coupled to a shaft 13 by means of a collar 123 which is splined on the shaft and is formed with inclined slots 125 co-operating with fingers 126 on a collar 127 secured to the diehead. The collar 123 is formed with a groove 138 engaging rollers 137 on a yoke 136 secured to a rock-shaft 134 operated by a shift-key 130, Fig. 11. The shaft 13 is connected by a friction-clutch to a driving-shaft and is provided, as described in British Specification 345,674 and U.S.A. Specification 1,518,904, with an arm co-operating with key-operated stops to arrest the die-head for die-selection. Normally the stops select lower-case dies, but on depression of the shift key, the die-head is partly rotated by means of the fingers and slots 126, 125, and the stops select uppercase dies. Key locks and interlocks.-A shift-lock key 130<a>, Fig. 10, is connected by a link 141 to an arm 142 on a shaft 143 provided with an arm 144, Fig. 11, engaging the shift-key lever 131. The shift-lock key passes through a slot 147 in a pin 145 which can be turned by means of a finger-piece 146 to hold down the shift-lock key by co-operation with a recess 149 therein. A crowding-ball device 15 prevents simultaneous depression of two dieselecting key-levers, and the shift-key lever is arranged to pass between the balls so that on depression of a die-selecting key lever, the shift-key lever is locked. To prevent depression of the blanking-die key 160, Fig. 11, when the shift-key has been depressed, the shaft 143 is provided with a finger 148 for obstructing a lug 161 on the blanking-die key. The keyboard is locked unless the plate-carriage is in position for presenting a plate between the dies. For this purpose the plate-carriage, when out of that position, depresses a bar in connection with a pivoted yoke 180, Fig. 10, and thereby causes the end 186 of the yoke to pass between the crowding-balls. The yoke has an aperture 185 which is normally in register with the crowding-balls.
