Figure 2 is a sectional elevation taken on avertical line through the centre of themechanism in figure 1. Figure 3 is an elevation of the same partsas shown in figure 1, showing them as theyappear when viewed from the opposite side ofthe bicycle to that from which Figure 1 isviewed. I A is a tempered spring steel band, one endbeing fastened by the screw D to the web ofsprocket wheel, the other end of the bandbeing fastened to the crank by the stud Hpassing through the web of the sprocketwheel by means of the slot M. B is a cylindrical drum fastened rigidly tothe lower bracket of the bicycle frame. The drum B is faced with material C, suchas leather, for the purpose of taking the fric-tion generated by the band A. The chain wheel is secured to the crank bythe stud H, and the two screws E E havinglarge heads F F, and moving in
