This I do by making a small cylinder shaped block B, Fig. 1, of the same length as the width of the spring, with a square hole through the center of it lengthwise, the same size as the square of the arbor E to which it is to be applied. This block which I term the arbor collet, has a hook or catch on the outside of it which attaches to the inside end of the spring in the usual manner. This collet being placed on the arbor close without making any alteration in them or taking them in pieces.
