A reel for winding the thread into skeins, from the spindle which was
taken from the spinning-wheel as soon as it was filled. By means of a
cog wheel and a worm screw within the box, and a pointer on its side,
the number of turns of the reel were easily counted, and that told the
length of the thread wound on it. As the wheel revolved it made a loud
click for each of a certain number of turns.
