ABSTRACT:
A mandril for mounting a cone used for winding thread or the like comprising in combination, a first cone-like member having a substantially conical outer surface, the member adapted to receive a shaft therein for use in mounting the mandril, the conical outer surface having abutment means thereon selectively extendable outwardly therefrom to thereby provide selectively, a protuberance on the conical outer surface and a second member, adapted to enter within the first member, means on the second member adapted to engage means on the first member when the first and second members are assembled together, to ensure locking and driving engagement therebetween, the second member also having means thereon cooperatively engageable with the abutment means and arranged such that, in a first position relative to the first member, the abutment means will not be extended by the means but in a second position relative to the first member, the abutment means will be extended by the means, outwardly of the surface to thereby provide the protuberance on the conical outer surface for use in positively securing the cone upon the mandril for driving engagement therewith.
