LOCOMOTIVE BOILER Application filed February 3, 1928; Serial N0. 251,508.
s'ive construction and ready applicability in locomotive boilers of present standard constructions, in the operation of which the crown sheet will be firmly supported, increase of Water heating surface be made, and circu- 'lation of water'in the firebox be promoted.
' The improvement claimed is hereinafter *fully" set forth.

In the practice of the invention, referring descriptively to the specific embodiment thereof which is herein exemplified as applied in a locomotive boiler of the standard com- I bustion chamber class, having a firebox, in-
dicated, as an entirety, by A; a waist or bar-' rel, indicated by B, and a combustion chamber, indicated by 0, two or more crown sheet supporting and water circulating members,- I59 1,1, are located in the forward portion of the combustion chamber. tical water walls, of substantially triangular outline, the upper and wider ends of which firebox, A, and the adjoining portion of the Said members arever- I are open to the space Withinthe boiler above 52 the crown sheet, 2. The upper ends of the ,plates which form the water walls, are secured, by rivets, to upwardly turned flanges 2a, onthe crown sheet and adjoining sheet of the combustion chamber, one or more rows of ct the radial staybolts, 2?), by which said sheets are connectedto the shell sheets of the boiler, being omitted, to afford space for the insertion of the water walls, as clearly indicated in Fig. 2. c: i
A pipe 4 leads from the waist of the boiler toa header 4a which communicates with the lower ends of each of the members 1. A pair of header supports 5 are secured at their front ends to the mud ring front portion 6 and at T5 their rear ends to a transverse bar 7 secured at itsen'ds each to a side of the mud ring. The header 4a is provided with the bottom .plate 46 which maybe removed'for the purpose of cleaning the header. Arch tubes 8 are provided, the rear ends of which are secured in the upper rear portion of the fire box A and the front ends of which are secured in the rear portion of the header 4a. A second set of arch tubes 9 are likewise supported at so their rear ends in the upper part of the rear end of thefire box A, the front portions of which pass between the water legs with their ends connected in the rear of the throat 10 of a portion 13of the waist B which extends 8 ,about the combustion chamber C. An arch 11 of fire brick is supported upon the arch tubes which extends through the front poriion of the fire box A'and the rear portion of I the combustion chamber C.
In the construction of-Figs. 7 to 9 inclusive,
is shown a modified structure wherein, instead of the supports 5, lateral supporting plates-12 areemployed, which,,in thepresent instance, are formed integral with the header 12a and have their outer ends 12?) secured to the sides of the mud ring 120.
