The long push-bar pilot coupler has been dis-placed by the pilot coupler, the construction andattachment of which differs with shape of the pilotused by each railroad company. Hence no attemptwill be made to illustrate the pilot coupler; suffice it tosay that the contour lines of the coupler itself are. Fig. Automatic Coupler for Tenders. standard with the Master Car Builders coupler onall cars. The couplers for the back of the locomotive tenderare, however, of not so great a variety. Where theconstruction of the tank frame will permit, it is quitecustomary to apply an automatic coupler quite similarto that on a freight car, but there are a large number of (422) LOCOMOTIVE APPLIANCES. 423 tenders in this country equipped with a plate couplerlike that shown in the accompanying engraving, orquite similar thereto. The coupler here shown ispivoted on the outside of the end sill of the tank by aconcentric pin, which gives to it the same circularpath it would have if it were pivoted four feet backfrom head, thus permitting it to have the requiredthree-fourths inch side play without the liability ofuncoupling. When tension is put upon it, it centersitself in line of draft and conforms to all the move-ments of the service. This form of coupler is alsomade with an elliptic buffing sp
