Two pairs of duplex pumps and three injectors, either ofwhich is sufficient for the purpose intended, are guaranteesagainst accident to the feed-water supply. The stokers are operated by a 4^2 X 4 Westinghouse stand-ard engine, whose motion is reduced through a screw gear, anda second engine duplicates thtf first, and is for use in case ofaccident.

The steam pipe is continuous, and any portion may be dis-connected without interfering with the rest of the plant. On the whole, this station is well designed, well lighted andwell managed ; and, with its interior finish of natural wood,always kept carefully clean, it presents an air of neatness instriking contrast to many larger and more pretentious stations. Safety Stop for Janney Couplers. The accompanying drawings show a safety stop devised toprevent the trouble caused by the draw-bar pulling out whenthe continuous draft-rigging is used. Where the M. C. SAFETY STOP FOR JANNEY COUPLER. draft gear is used the block, as shown in figs, i and 2, is attachedto the tail end of the coupler. The M. C. B. standard callsfor the two holes which are shown, in the first of which fits theboss of the casting. Through the second hole is passed thebolt which holds the casting to the draw-bar. In case the headof the tail bolt is too long to allow this, a strap, as shown in , is used. When the Graham draft-rigging is applied it is necessary toplace a casting across the bottom of the draft timber to form astriking plate for the casting to catch on. With this gear thecasting is fastened to the bottom of the draw-bar instead of thetop as in the other, being held in position by the small arrangement is shown in fig. 4. It can be readily seen that in case of the tail bolt breakingwith either construction the casting will prevent the draw barbeing pulled out. The arrangement is devised by the McCon-way
