Proceedings Railway Club of Fig. 6 shows style A, flexible stay, the head being quiteflat and having but little area where such is needed. This bolt has been used by several of the railroads and wasone of the early designs to afford flexibility in a water spacestay.

The black lines surrounding the head and shank of bolt (A)showing clearance in cap C, and sleeve B, will give a clear ideaas to how incrustation might affect the ease of movement ofthis bolt. The sleeve and cap are made of brass by some roads,and malleable iron by others. Malleable iron is too porous to be of any serviceable valuein any style of a flexible bolt. *j&//c /?/}. ftfxiBie 57
