18.073. Hollingworth, E., [Crompton & Knowles Loom Works]. Aug. 9. Loom shuttles. changing bobbins and the like in, automatically.-The hopper or magazine consists of plates 11 connected by transverse bars 12, 121, 122 and provided with two series of channels 112 for the heads and tips of the bobbins &c. respectively, the magazine being provided with lugs or ears by which it may be reciprocated along horizontal bars 9, 10 by lever mechanism 21, 22 connected with the pattern mechanism, preferably that of the drop-box motion. The lower end of each channel 112 is preferably inclined or curved forwardly, and is provided with alight leaf-spring. A transferring- device 19, connected to a rod 16, is provided for each channel, and is adapted to act upon the lowermost bobbin &c. in the channel. When a change of filling is indicated and the connector 31 is operated, an arm 29 rocks a lever 28, 281, pivoted to a lever 26, 261, against spring action, and, on the beat-up, a dagger on the lay engages the arm 28 of the lever and moves the lever 26 about its pivot against spring action, thereby depressing a lever 23, which has an engaging-end 23'. The end 231 depresses the arm 161 of that rod which is immediately above the shuttle 7, and the corresponding transferring-device pushes a bobbin &c. from the corresponding guideway into the shuttle. The rod 16 is returned to normal position by a coil spring 18, which bears against the arm 161 and against a fixed bracket 171.
