ABSTRACT:
An improved electromechanical filling yarn indicator for use in a pattern-controlled outside filling yarn supply weaving loom to translate motion of fill yarn control cords of a jacquard harness or other pattern control mechanism into electrical signals for transmission to activating solenoids of fill yarn control box selectors which present selected fill yarns from outside filling yarn supply packages to the fill yarn carrier for insertion into the warp shed of the loom. The fill yarn indicator comprises a plurality of slidably movable bars, each having an electrical contact connected to a power supply and engageable with one of a pair of electrical contacts spaced along the path of sliding movement of the bars. Each contact of the pairs of contact is connected to a respective actuating solenoid of fill yarn control box devices located on either side of the loom. The position of each slidable bar to bring its electrical contact into communication with either one of the pairs of contacts spaced along its path of movement is controlled by a fill yarn control cord attached to each end of the bar, such that movement of the cords and bars in response to pattern information from the jacquard mechanism provides electrical signals to selected of the control box solenoids to present a desired fill yarn to the fill yarn carrier for insertion into the warp shed during weaving operations.
