A perforated tape 27, Fig. 1, is drawn from a roll 28 by a motor 46 which is switched on and off by a feeler 49 to maintain a loop of tape ahead of a reading unit 26; the tape is pulled through the unit intermittently by a motor 36 acting through a slipping clutch 32, the output shaft 30a of which is allowed to make one revolution each time the armature 38 of a magnet 37 is disengaged from a tooth 39a; the tape is rewound on a roll 29 driven through a slipping clutch 43. In the reading unit, Fig. 5, spring-loaded plungers 93 are lowered by magnets 89, whereupon those plungers which pass through holes' in the tape 27 make electrical contact with terminals 73 in circuits controlling the shedding mechanism and the change-box motion; springs 96 raise the plungers to permit movement of the' tape; to enable the tape to be placed in position, the top of the unit is hinged at 79 and normally held closed by a latch 103. The unit may be remote from the loom and may control several looms. Shedding mechanism, Fig. 8. Energization of solenoids 166, corresponding to holes in the pattern tape, brings associated hooks 116 into the path of griffes 133; unselected hooks rest by their ends 118 on :a comberboard 119 which is moved oppositely to the griffes by bell cranks 142, 157 and linkages 146, 143, 158, so that a closed centre shed is formed. Change-box motion, Fig. 16. Shuttle boxes 181 at opposite ends of the loom are simultaneously depressed afterevery pick by cams 192, and are arrested as they rise by a lug 198 on each box encountering a latch 197 selected by the pattern mechan- 'insm described above. Each box has as many cells as there are shuttles, and the two boxes move in unison. Shuttle boxes and shuttles, Fig. 17. A motor 201 drives each shuttle through worm and bevel gearing and two vertical shafts 214 each carrying a pair of driving wheels 216, opposite which are spring- loaded idler wheels 217. Pick-up strips 219 on the shuttle engage strips 222 on opposite sides of the shuttle box cell, sufficient impetus to propel the shuttle across the loom being-generated whilst the shuttle is traversing the box. A contact (not shown) on the exterior of each cell registers with a fixed contact so that only the cell that is level with the shuttle race receives current.

Title: Improvements in spinning and twisting frames and the like
IPC: D01H13/18
Filed: 1922-07-25
Abstract: 205,877. Rogers, F. H., (Eclipse Textile Devices, Inc.). July 25, 1922. Delivery, stopping; roving-guides.-In an arrangement in which the roving is clamped behind the rollers by a device operated by a member controlled by the tension of the thread, the stop device can be reset when the roving has been stopped without interfering with the thread-controlled member. In one arrangement, the stopdevice comprises a pivoted plate 14, Figs. 1 and 6 with a V-groove 16 to engage the roving, which plate is supported by and normally rests against a block 11 secured to the bar 13. The plate is operated by a pivoted trigger 17 the tail of which is struck, when the thread breaks, by an arm 26 on a pivoted thread-controlled lever 21. If the plate is reset, the lever 21 can be moved back past the trigger 17 without operating the plate 14. The lever 21 is in two parts pivoted at 24 to allow the outer half to be raised without operating the stop-device. The guide 10 on the lever takes the place of the usual guide eye. A series of locking-plates 31 may be moved to engage the levers 21 to prevent their operation. These plates may be mounted on a bar 32 connected to the belt-shifting device. The roving-guide 9 may take the form of a slotted bracket carried by the bar 28 or of a slot in the bar itself. The clamping-device may comprise two parallel plates 38, 40, Fig. 11, supported from the bar 13, and two blocks 44, carrying plates 45 to grip the roving, pivoted between them. The blocks are pivoted on pins 42 and are operated by pivoted triggers 50 carrying extensions 48 adapted to be engaged and moved by arms 27 on the thread-controlled levers. A pin 47 rests on the plate 40 to maintain the block in its normal position. A pin 47a limits the relative movement of the block 44 and trigger 50. If the arm 27 is moved back, after the plate 44 is reset, the lost motion between the trigger 50 and block 44 prevents disturbance of the block. A pivoted board with a flanged edge may be arranged at the front of the frame under the thread controlled levers, to collect dust, lint, &c. and is adapted when raised, to support a series of levers in their raised position. The stopdevice may be applied to a twisting-machine with a single pair of delivery rollers.
