This plug serves the double pur-pose of preventing any leakage which may escape past theball joint, and tends to slightly spread the cup and so insurea perfectly tight joint between cup and outside sheet. Asmall space between the ball head of the bolt, and this plugpermits of the approach of the two plates of the fire-box towardeach other. When it is desired to remove a bolt the plug is removed, andthe inside end having been clipped and drilled, the bolts can. Flexible Staybolt. be withdrawn without injury to or disturbance of the cup can be put in so as to stand flush with outside sheet,and so the bolts may be placed behind frames, brackets, etc.,without difficulty. This and other designs of flexible staybolts are sometimescriticised on account of the large holes in the outer fact, however, that flexible staybolts requiring these largeholes have been in use for years with no bad results, is con-sidered sufficient answer to that objection. Destructive testsof Mr. Barnes staybolts have been made at Purdue Uni-versity. The tests show an ample margin of strength and cupbolt and head proved to be almost co-equal in strength. Flexible Staybolts in India American Engineer and Railroad Journal, Oct., 1900, p. is a communication from Mr. Cornelius E. Cardew,Locomotive and Carriage Superintendent, Burma Railways,in which he claims priority of invention of flexible stays forMr. Wehreufennig, of Austria.
