Title: In looms for weaving, the substituting of weft charged shuttles for those from which the weft has been depleted
IPC: D03D45/34
Filed: 1939-05-03
Abstract: 528,285. Looms. CRABTREE & SON, Ltd., D., and FELTON, W. May 3, 1939, No. 13174. [Classes 142 (i) and 142 (iii)] Shuttle-changing mechanism.-The slay x is mounted on links pivoted at e and f and is oscillated by the usual crank d. The shuttle cell a and an extra cell b are slid horizontally on the slay by levers 22 and crank discs 21 mounted on the slay and driven by a chain 9a from a shaft 8 carried by the loom frame. A toothed wheel 7 on the shaft 8 gears with toothed sectors 10b, 10d on a wheel 10 and has two cut-away teeth 7a, 7b to engage plain parts 10c on the wheel 10. On indication of weft failure from any cause, the shaft 8 and the crank discs 21 are rotated half a turn to bring the cell a beneath the magazine 3 and the cell b into position to receive the exhausted shuttle ; the shuttle support 3a is knocked out of the way and a new shuttle 2 drops into the cell a while the higher shuttles are retained by levers 3g. The shaft 8 and crank discs 21 then complete their rotation so that the new shuttle is brought into picking position and the exhausted shuttle falls into a receiver 25 from the cell b, the bottom and one side of which collapse as shown in Figs. 1 and 3. The shaft 23 carrying the wheel 10 is driven by a chain 11b from the low shaft 12. In one arrangement the weft-failure indicating rod 5 allows the wheel 10 to be clutched to the shaft 23 only during one revolution, but as shown, the wheel 10 is fixed to the shaft 23 and the rod 5 slides the pinion 7 on its shaft 8 into position to engage the toothed sectors 10b, 10d. After one revolution of the wheel 10, a cam 16 carried by wheel engages a roller 6b on a lever 6 and disengages the pinion 7 from the sectors 10b, 10d. Stop motions.-The magazine 3 is pivoted at 30. If the new shuttle fails to clear the magazine the same moves with the cell a and through a link, levers &c. 31, 32, 34a stops the loom. The loom also is stopped by the member 26 and dagger 15a if the shuttle fails to box in either the cells a, b. In the working position of the cells a, b the shuttle swell 13 can raise the dagger 15a through the lever 13b slotted link 13e and lever 14, as shown in Fig. 3, but in the replenishing position of the cells a, b this linkwork is out of action and the shuttle swell 17 acts on the lever 14 through a lever 17a as shown in Fig. 6.
