Weaving.) An apparatus for laying out the threads of a warp and dividing them into two sets.

Warp-dyeing machine.

Warp-beaming machine.

It comprises a large wooden reel a of 12 or more sides mounted on a vertical axis and rotated by an endless band passing around a horizontal wheel at its base, and a second wheel turned by a winch. One sixth of the whole number of threads, on their bobbins, are mounted on a frame b, called the travers, the bobbins being set loosely upon spindles, so as to revolve freely. The yarns are passed through the eyes of pins on the jack or heck-box c, which has a rising and falling motion by reason of its being connected by a cord passing over a pulley to the axis of the mill a. The pins in the heck-box are arranged in two sets by each alternate pin being connected to one of two [2726] movable bars in the heck-box, so that by pushing up one set of pins, after the yarns are passed through, the warp is divided into two leas, one for each of the heddles of the loom. The ends of these are knotted together, and they are passed over two pins on the mill, which is then turned by means of the winch. The heck-box rises, and the yarns are wound spirally on the reel; the movement is then reversed, and the box descending by its own weight, a spiral layer is laid on in the opposite direction, and so on until the yarns are all wound off the bobbins.
