Abstract

842,972. Stop mechanism for textile machines. MACKIE & SONS Ltd., J. Oct. 1, 1956 [Sept. 29, 1955], No. 27758/55. Addition to 732,549. Classes 120(2), 142(1) and 142(2). The stop mechanism of the parent Specification is modified in that the abutment yields when engaged by the detector or a part acting with it and in yielding operates a device for stopping the machine. Further the stop mechanism is adapted for the control of weft yarn in a shuttleless loom, for the control of yarns passing from the-creel to the beam of a beaming machine and for the control of yarns to be twisted in a twisting machine. The embodiment shown is for use in a shuttleless loom and consists of a detector 1 suspended from a pivot 2 at the end of an arm 3 caused. to rock about an axis 4. The detector 1 co-operates with the weft yarn 20 as it passes over support 21 which constitutes the abutment. The support 21 is pivoted at 22 and bears against the plunger 23 of switch 24. In normal operation as the detector 1 is moved into contact with the yarn it is swept aside by the yarn into the position shown in dotted lines at 1<SP>1</SP>. If the yarn is missing or running below speed, however, the detector is not swept aside and in consequence bears on the support 21 causing the latter to yield and rock about its pivot 22 to operate the switch 24 to stop the loom. Similar arrangements are shown for application to a beaming operation and to a twisting machine. In the latter the mechanism controls a mechanical latch which in turn controls a gripping device stopping the feed of the yarn.
