13,803. Pilkington, W. W., Whittaker, J., Bradshaw, R., and Briggs, J. June 27, 1910. Shuttles, changing bobbins and the like in, automatically; shuttle boxes; picking-motions. -In weft-replenishing mechanism for overpick looms, the transferrer 1, Figs. 1 and 2, is pivoted on a shaft 2 supported in brackets on the breast beam 3 so as to be on a level with or slightly above the shuttle, and a flat cop magazine 100, Figs. 1 and 3, is employed wherein all the cops 104 but one are retained above the transferrer, the lowest bobbin being dropped from the magazine and guided by retaining-jaws 127, 128, Fig. 1, or 118, 119, Fig. 3, into position beneath the transferrer. One of each pair of retaining-jaws is pivoted and spring-pressed towards the other, so as to yield when the transferrer is depressed and allow the cop to be pressed into the shuttle. The magazine may be pivoted at 130, Fig. 1, and be normally pressed by a spring out of the path of the picking- mechanism. When the transferrer is depressed, it causes the magazine to be moved into the path of the picking-mechanism, so that, at the moment of transfer, the retaining-jaws are in position to guide the cop into the shuttle, the jaw 128 having a spring-controlled tip 129, which yields to allow the cop to pass. A fixed magazine may be used, the retaining-jaws being pivoted, or, as shown in Fig. 2, the back jaws 127 only may be pivoted and be normally pressed towards the fixed front guiding-jaws 128 by springs, so as to be normally out of the path of the picking-mechanism, the back jaws 127 being moved into the path of the picking-mechanism by the transferrer, so as to guide the cop properly into the shuttle. The retaining-jaws are so curved or shaped as to cause the cop to clear the picking-shaft 125. The shaft 125 is fixed farther back than usual, to afford clearance when the cop is being transferred. Both back jaws may be hinged to a spring- pressed flap 122, Fig. 3, or this flap may replace the back jaws. The flat cop magazine comprises three.endless chains 98, 99, 102 supported by chain-wheels 88, 89, 97 and chain wheels or pulleys 100, 101, 105, the cops being supported one above another by the inner parts of the chains 98, 99. The tips of the cop skewers may enter the links of the chain 99, or may be placed in cups or hooked projections 107 fitted to or made integral with the links of the chain, as shown in Fig. 8. A flange 108 projecting from the magazine frame 86 prevents end movement of the tips. A small guide or flange is also placed inside the chain 98, which has external cups or carriers 110 for the heels of the pegs or skewers, while a third rib placed beyond the carriers 110 prevents the heels from leaving their position. The cups &c. 110 are preferably made in halves from the links of the chains, each half having three sides 111, 112, 113, Fig. 7, struck upwards to form half the cup, and the remaining side turned downwards to form one of the sides 114 of the chain link. The chain-wheels 88, 89, 97, Fig. 3, are carried by shafts geared to a shaft driven by ratchet gearing each time the transferring-mechanism is operated, the lowest cop 104 in the chains dropping therefrom into the retaining-jaws 118, 119, 120 being directed by a guide-piece 117 and being subsequently inserted into the shuttle as described. The retaining-jaws preferably engage the cop skewers, and those for the tips of the skewers are preferably arranged so as to leave a clear passage for the weft ends. A lay bunter operates the transferrer through the medium of a bunter arm 65, as described in Specification 15,336/10. According to the Provisional Specification, the bent end of the weftfork slide lever comes into contact with one arm of an L-lever mounted on a stud on the top of the breast beam, this L-lever giving an endthrust to a rod-controlling mechanism, whereby adjustable bunters on the lay are enabled to operate the transferrer-mechanism and mechanism for driving the ratchet gearing in connexion with the chain-wheels 88, 89, 97. If the shuttle is incorrectly boxed, a detector or feeler working in a groove in the shuttle-race near the shuttle box operates mechanism which prevents the transferrer-mechanism from being actuated. A small leather tab connexion is made to the picking-band, and is connected to an oscillatory arm carried by a bracket fixed to the back of the lay and operated by the picking-mechanism, and is returned by a spring to afford clearance for charging, the picking-spindle being raised for the same purpose.
