[Also in Division G4] The co-ordinates of points along a curve 18, Fig. 1, are determined electrically by moving an index member 20 along the curve, the member being attached by spring-biased strings 22, 24 to carriages 26, 28 movable along Y and X axes of a work surface 14 on which the curve 18 is located, the amount of string being taken up on e.g. the Y carriage 26 being sensed electrically and used to cause a motor 42 to drive the X carriage 28 along a screw 40 parallel to the X axis to a corresponding position which is sensed and signalled by encoders on the carriages. As shown in Fig.2, the carriage 26 (28) is mounted on lead screw 32 (40) and guide rail 30 (38) for longitudinal movement when the screw is rotated by a motor 34 (42). Mounted on the carriage is a shaft 48 (56), biased by a spring 50 (60), and carrying a down 46 (58), to which the string 22 (24) is fixed, the slider of a potentiometer 54 (64) whose winding is fixed to the carriage and encoder 52 (62) to transmit a signal representing the Y (X) co-ordinate of the carriage. At the end of lead screw 32 (40) is a further potentiometer 36 (44). Potentiometers 54, 44 are connected in a bridge curcuit Fig.3, (not shown) whereby movement of the index member 20 along the X axis produces rotation of shaft 48 and displaces the slides of potentiometer 54. The bridge unbalance is fed to motor 42 to rebalance the bridge by rotation of lead screw 40, repositioning the carriage 28 and adjusting potentiometer 44. In another embodiment Fig.4, movement of the index member 80 in the X direction alters the tension in the X string 82, whereby a spring- biased sliding member 98 carrying a vane 102 is displaced to produce an output from a differential photo-cell detector 104, the output signal energizing a motor 106 to restore the tension in the X string 82 to its neutral value, and a motor 124 to displace the X carriage 110 along lead screw 122 to follow the index member.

Abstract: A gripper shuttle 1 withdraws twice the length of weft required for one pick and lays the second, pick as it returns through the shed. In Fig. 1 (not shown) the length of the shuttle race is twice that of the fabric plus the length of the shuttle.  In Fig. 4 (not shown) the weft 13 extends through an eye 22, through clamps (not shown), over the shuttle box, to a suction tube 18. On picking a cam 11 opens a spring catch 4 so that on closing it grips the weft; after the first pick is beaten up shears 17 cut the weft, the tube 18 descends and opens the clamp (not shown) so that pivoting of the eye 22 withdraws all but a small portion of the weft from the tube 18 which then rises so the clamp grips the weft in readiness for the third pick.  On return of the shuttle for the second pick a cam 23 opens the catch 4, the shears 17 sever the weft and the cut end is sucked down a tube 24.  To reduce the width of the sley a weft gatherer may be provided on the far side of the loom.  The gatherer comprises a pivoted arm 33 which draws the weft through the shed and over fingers 34 which are radially adjustable for different fabric widths.
