Fig. 2 is a section on the line 2of Fig, I, looking from the right-hand side, and Fig. 3 is a sec-tion on the line 3 of Fig. i, looking from above. The super-heaters are arranged with tubes (A) situated within the smoketubes (B) of the locomotive. The superheater tubes (A) areconnected at their ends to headers (C) and (£>), the headers(C) being provided with a connection (E) to the steam spaceof the boiler. The superheater tubes (A) are disposed asshown, and are connected to their headers by bridge pieces (F)bearing upon flanges (G) formed on the superheater tubes andsecured to the header by means of the holts (//). The headers FIG. 1. APPLICATION OF SUPERHEATER TO ALL BOILER TUBES. Superheater Co., have been granted patents in Cassel, Germany,on an entirely new arrangement which may be applied withoutany interference with boiler conditions, provided thatthe flues are of 2l4 in. diameter, or at least above two inchesin diameter. One of the fundamentals in superheater design up to a com-paratively recent period was to provide a superheater on eachside of the boiler, and to allow each superheater to supply steamto the cylinder on one side of the locomotive only. It has beenadvanced, in this connection, that this construction makes it oftendifficult to obtain a sufficient quantity of highly superheatedsteam for each cylinder. On the other hand, as the steam isonly drawn from each superheater twice per revolution of theengine the claim is also advanced that the superheaters are notworked to their full capacity. In the arrangement herein illustrated, in which interest
