The rims or sections of the gear are attached to the hub independently. When the teeth are worn out and nolonger serviceable the rims are removed and new ones substi-tuted, thus making practically a new gear. The ease with whichthis can be done can be readily appreciated by examining theaccompanying illustrations. Where the hub piece and the rimcome in contact they are beveled in such a way as to make aperfect fit, thus preventing all lateral motion. To escape the pos-sibility of the rim revolving or slipping on the center piece, asteel safety key is placed through the hub and rim section, lock-ing them absolutely. The weight and amount of metal in theentire gear is about the same as in the ordinary type. There is,however, a considerable saving to users of this gear, becausewhen the rims are worn out they can be replaced without buy-ing a new hub. The great advantage o
