ABSTRACT:
A skewer assembly comprising upper and lower portions threadably connected together and extending axially along a longitudinal axis, the upper portion having a tapered end, the lower portion having a sleeve with a bush for engaging a rotatable crank pin of a Barber Colman spool winding machine. A cam rides in the lower tubular portion and is actuated by the crank pin so as to undergo upward and downward movement. The upper tubular portion is provided with a plurality of longitudinal slots distributed around the circumference of the upper portion and holding dogs are pivotably mounted in the slots and are actuated by a spindle which is secured to the cam to follow the movement thereof. The dogs are thus pivotably moved between retracted and extended positions for selectively holding and releasing a bobbin on the skewer. Each of the dogs has a first end region with a convexly bent portion having an extremity extending obliquely relative to the longitudinal axis radially inwardly and axially upwardly to form a guide for a bobbin as it is received by the skewer assembly.
