Claim:

This invention relates to chucks for screw machines, lathes, etc., and more particularly to an improved construction of collet which, co-operating with the chuck sleeve, will secure the centering of the work throughout substantially the length of the collet and especially at the ends of the collet, with the result that the work will be accurately centered and be firmly gripped during the operation of the lathe or machine.
