. Railway and Locomotive Engineering. branch steam pipesthat lead to the cylinders. The joints of the pipe coils to the lowerface of the header are held in place bybolts, the heads of which are shown onthe upper face of the header, the lowi-r pipe to the branch steam pipes the tem-perature of the steam is increased by itsnear contact with the heated gases findingtheir way through the enlarged use of the brick arch in connectionwith the superheater is favorable to ahigher degree of superheat. As is wellknown, the brick arch acting as a baftleplate and presenting a projected body ata high degree of temperature produces alonger and brighter flame, thereby givingthe gases a greater amount of time to mixwith the current of oxygen as well as ahigher degree of heat to consume thegases and thereby create a more completedegree of combustion. The brick archalso has a tendency to project the flameand hotter gases through the larger flueswhich are located in the top part of theboiler. .As nia> be readily imagined when a. FIG. 2.

Thejoint is a ground ball joint, the concavebeing in the header and the convex at-tached to the pipe collar. The coiledpipes are thus readily removable. Thecoils of pipes are kept in place near theupper edge of the enlarged flues by meansof lugs that rest on the bottom of the en-larged flues. It will be observed that thelarge flues, through which the smallercoiled flues pass, are diminished in size asthey approach the back flue sheet. Thisadmits of an enlarged water space nearthe flue sheet besides thickening andstrengthening the flue at its junction withthe flue sheet. It will thus he seen that the applianceis simply a means of conveying the steamthrough a series of small pipes to a pointas near the fire-box as safety will permitand by exposing the surface of the smallpipes conveying the steam from the dry locomotive is runni
