Heck-box

The threads pass from the bobbins to the frame through an instrument called a jack or heck-box, or simply a heck.

The heck-box moves up and down a post, the motion being regulated by a cord passing over a wheel or pulley and wound round the axle of the reel, and unwound alternately, as the box moves up or down the post.

The heck-box slides vertically on a bar as the reel rotates, and thus disposes the warp spirally on the reel.

For this class of work some very handy creels, heck boxes, and horizontal warping mills, with all the latest adjustments, are offered to the silk trade.
