When such a fraction had been 55 wound on a new spindle, the stop motion stopped the package again in order that a new supply bobbin might be furnished. Moreover, in using such a stop motion, advantage would not ordinarily be taken of a break in the yarn when the package was approaching its proper size to remove the package and begin a new one. In view of the fact that the yarn is commonly marketed by Weight, there is no disadvantage in winding packages of slightly different diameters, and with an invention such as I have described herein, the package may be permitted to wind even after it has grown to such a size that it contacts with the spoon-shaped portion of my package size indicator, thereby permitting an operator to finish Winding a supply bobbin or to take advantage of a broken yarn to remove the package and start another.

The irregularities on the package surface are sufiicient to impart to the spoon-shaped portion of my indicator an appreciable motion amply sufficient to attract an operators attention. The smooth under-surface of my spoon-shaped portion and the lightness of my package contactor result in the fact that the threads are neither weakened nor cut by their contact therewith.

It is evident that various changes may be resorted to in the construction, form and arrangement of the several parts without departing from the spirit and scope of my invention, and hence I do not intend to be limited to the particular embodiment herein shown and described, but what I claim is:

1. In a winding machine, a winding spindle carrying rock arm provided with a ledge, and a package size indicator comprising a support adjustable in a linear direction only and adapted to abut said ledge, and a package contacting means pivoted to said support.

2. In a winding machine, a rock arm, a winding spindle carried thereby and arranged to support a package during the formation thereof, an adjustable support provided with a stop on said rock arm, and a strip of sheet metal pivoted to said support, said stop being adapted to keep said strip out of contact with the package until the package reaches a predetermined size, said strip being provided with a spoon-shaped recess in its free end, a wall of said recess being arranged to engage the package when the package attains a predetermined size.
