562,167. Looms with automatic weft replenishment. TRIGGS, W. W. (Crompton & Knowles Loom Works). July 23, 1942, No. 10317. [Class 142 (iii)] In a weft replenishing loom interchangeable supports are provided for holding the reserve bobbin magazine M in either high or low position so that a shuttle box can be replenished either in high inactive position or in low active position. Links 252 connect the upper part of the magazine to a rod 246 carried by an angle bar 245, and guided in a slot 253 in the loom frame to assist in holding the magazine in its proper position. The weft replenishing mechanism which includes bobbin transfer mechanism is mounted upon the magazine and a weft detector is arranged to rise and fall with the shuttle box and to indicate weft exhaustion in either position. The transfer mechanism comprises a normally inactive latch member movable to transfer position upon indication of weft exhaustion, and a bunter on the shuttle box is moved forwardly towards and operates the latch. The latch is operated onLy when both the magazine and the shuttle box are in the high or the low position. The loom may be used with a 4 x 1 setting for automatic weaving with several colours, with a 4 x 2 setting for automatic pick-and-pick weaving for mixing wefts of the same colour, and with a 4 x 4 setting for non-automatic pick-and-pick weaving ; the weft supply magazine M can be supported in raised position for the 4 x 2 setting, in a lower position for the 4 x setting, and can be swung upwardly and backwardly out of the way for the non-automatic 4 - 4 setting. The weft-replenishing mechanism is described in Specification 562,193. Specifications 489,252 and 558,966 also are referred to.
