Title: Method of and apparatus for handling coiled metal strip
IPC: B21C47/24
Filed: 1954-06-10
Abstract: 752,203. Unwinding. UNITED ENGINEERING & FOUNDRY CO. June 10, 1954 [June 10, 1953], No. 17072/54. Class 83 (4). A coil of metal strip is partially uncoiled at a first station and the partially uncoiled coil then passes to a second station where the uncoiling is completed. A coil stored at a station A, on an entry ramp 10 is allowed, on lowering a stop 11, to roll to a station B where it is supported on rolls 13, 14, at least one of which is driven, against a pivoted stop 17, the stop 11 then being raised. The stop 17 is then lowered, so that the coil settles on the rolls 13, 14, a pivoted guide 32 resting on the stop 17 descending with the stop. The coil is then rotated until its leading end comes between the rolls 13, 14 and above an electromagnet 21 which is then raised and energized to hold the end of the strip. The roll 14 is then raised by a pinion 16 engaging a gear segment 15 which carries the roller 14 and pivots about the roller 13, to discharge the coil which rolls onto a lift 26 at a station C, the strip end being held by the magnet 21 so that the stripping effect gives the end a permanent set. After de-energizing the magnet the lift 26 is raised to present the coil to uncoiling cones 25, which after engaging the sides of the coil rotate it to rewind the strip end, a roller 31 on a pivoted arm 27 being moved down to press against the coil. The arm 27 and stop 11 are electrically connected so that stop 11 cannot be lowered until the arm 27 is raised. As soon as the end of the strip is at the top of the coil the coil is rotated in the opposite direction to uncoil the strip through a guide 42, formed in two parts moved in to engage the sides of the strip, and between opened upper and lower rolls 39, 41. The upper roll 39 is then lowered to grip the strip and feed it into a mill or other processing means, and then raised when the mill engages the strip. The arm 27 is then raised and the stop 11 lowered to allow a second coil to advance to the station B. After a substantial portion of strip has been uncoiled from the first coil at C, the lateral parts of the guide 42 move apart to free the strip and the cones 25 disengage the coil which then rolls between side guides 34 into cradle rolls 35, 36, 37 at a station D and where the uncoiling is continued. The leading end of the second coil, iri the meantime positioned at the station C, is then inserted between the rollers 39, 41 over the trailing end of the first coil, the rolls 39, 41 being closed to forward the leading end of the second strip as the trailing end of the first strip passes.

Title: Improvements in selectively operable devices for selective signalling systems
IPC: B61L7/08
Filed: 1921-06-22
Abstract: 185,871. Western Electric Co., Ltd., (Western Electric Co., Inc.). June 22, 1921. Addition to 117,170. Selectors.-The seelctors described in the parent Specifica tion are modified so as not to be operated effectively by current impulses which follow each other sufficiently rapidly, for instance Morse signals. In the examples shown the step-by-step element on the reception of rapid impulses, is first advanced to a predetermined position and subsequently held there until the impulses cease. In one example, Fig. 1, the S-shaped member 10 rocked by the armature 9 operates by means of pins 11, 12 a lever 13 at each movement in either direction of armature 9. A stepping-pawl 15 on the lever 13 operates a ratchet 17 and sector 20 and a pawl 37 held normally out of engagement with the ratchet by a pin 39 on the lever 13 is arranged to hold it but not the sector 20 during movement of the arm 10 between its extreme positions. The ratchet 17 carries an element 26 carrying at predetermined points pins 29, 30, 31 adapted to engage the end 35 of an arm 32 which bears against an insulated roller 34 carried by lever 13. Normal operation is effected by sets of impulses spaced so as to allow complete discharge of condenser 40 through resistances 41, 36 in series. The ratchet is held in the various positions to which it is advanced by pins 29, 30, 31 and ultimately an alarm circuit is closed through contacts 27, 28 arm 32 and pin 31. Operation by morse impulses. The first prolonged impulse allows the condenser 40 to be charged and the ratchet 17 and sector 20 advanced one step. An arm 24 on the latter makes contact at 25 and short-circuits resistance 36. Subsequent morse impulses step round the ratchet 17 and sector 20 until the arm 24 passes off the contact 25. The ratchet 17 is held in this position, but the sector 20 is returned by the spring 21,. the contacts 24, 25 being so shaped, Fig. 2, that contact is made continuously during the advancement of the sector 20, but only momentarily on its return. resistances 36, 41 are then again in series, and further operation by morse impulses is impossible. In a modification, Fig. 3, the sector 20 is emitted. The resistance 45 is normally short-circuited through contacts 47, 48. After the element 26 has been advanced to a predetermined point, the holding-arm 32 engages an insulated pin 44 on the element 26, contacts 4i, 48 are opened, and further rapid impulses do not advance the ratchet.
