MICHAEL, OF ELMAHURST, ILLINOIS?, ASSIGNOE 0F ONE-HALF T0 THE BALDWIN LOCOMOTIVE WORKS, OF PHILADELPHIA, PEHNSYLVANUm A CORPORA- @ION OF PENNSYLVANIA LOCOMOTI'VE CONSTRUCTION .Application filed May 3, 1929. Serial No. 360,193.

My invention relates to .railway rolling stock and particularly tothe construction of cylinder and boiler saddle structure of a locomotive and the combination therewith of a smoke-box mounted on the saddle and a feed Water heater contained in the smoke-box.

t is customary to provide pipes leading from the steam valve chambers and mounted on the outside of the smoke-box and extending through the Wall of the latter to a feed water heater carried in the upper portion of the smoke-box.

The main obj ect of my invention is to eliminate a substantial part of this piping and to simplifythe construction and reduce the labor of assembling thepiping and other structure and also to reduce the likelihood of undesirable leakage of air into the smoke-box due to the presence of joints where the piping would ordinarily extend throu h the smoke-box wall. I attain this object gy providing an exhaust steam passage, in addition to the main exhaust steam passage, in the saddle structure itself and having a discharge opening in the web plate of the saddle which supports the boiler, this opening leading to the interior of the smoke-box.

@ther more detailed objects of my invention and the means for attaining the same will be apparent :from the detailed description of my invention and from the accompanying drawings in which- Figure 1 is in part a top View and in part a horizontal section taken on the line 1-1 of Figure 2. n

Figure 2 is a vertical -transverse section taken on the line 2-2 of Figure 1.

Figure 3 is a side elevation of the saddle and feed water heater members, the adjacent portion of the smoke-box being shown in broken lines. y

Figure 4 is a vertical longitudinal section taken on the line 4-4 of Figure 1.

Figure 5 is a vertical transverse section taken on the line 5-'5 of Figure 3.

Figure 6 is a vertical longitudinal section taken on the line 6 6 of Figure 1.

Figure 7 is a detail horizontal section taken on the line 7--7 of Figure'2.

Preferably, although .not necessarily, my

saddle structure is formed in one piece and is integral with the locomotive bed or `forward framing members 1. l illustrate a portion of the bed of box-shaped cross section and having the steam cylinders 2 and the steam valve Y chambers 3 formed integrally therewith. The cylinders and valve chambers on oppomain exhaust steam passages 7 7 which lead from the ends of each steam chamber 3 transversely and longitudinally and upwardly of the saddle through the center of the web plate 5 where they form a seat 8 upon which an exhaust nozzle (not shown) may be mounted.

I provide additional or by-pass exhaust steam passages 9 leading from the main exhaust steam passages 7 at a point abreast of the front end of the steam chamber and extending transversely and upwardly of the saddle and through the web plate 5 near the front of the latter and the outside ange of the web plate is projected forwardly as indicated at 10 to accommodate the upper end of passage-way 9. This passage-way 9 terminates 'in a flanged portion 11 having a seat 12 for mounting a pipe 13 which is curved concentrically with the boiler shell and leads to a feed water heater 14 carried in the upper portion of the shell. Y

The steam passages 9 on opposite sides of the saddle preferably have acommon dis charge outlet 15 and only a single pipe and pipe connection is required for the feed water heater steam line and this connection is located on the inside of the smoke-box, thus reciprocating water pump 17.

projects outwardly fromthe upper wall 18 of the valve chambers 3 through the main exhaust passagefway 7 I provide a projection 19 at the junction between passages 7 and 9 and this eliminates undesirable back ressure v in the main exhaust passage-way which would be present if this projection were not provided'or if some other corresponding device were not used.

I also desire to simplify the complete locomotive structure by 'forming a bracket 16 integrally with thesaddle for the purpose ofmounting a combined steam cylinder and This vbracket the saddle structure which extends between the right-hand steam chamber4 3 and the.v correspondingside of the. boiler supporting web'plate 5.

It will be understood that the location and formation of the elements of my novelsaddle structure `may be' varied fromthat shown I without departing from the spirit of'my in- 4 I cylinder mounting elements of the saddle and my invention also contemplates the use of a saddle split along the longitudinal center line of thelocomotive in accordance with the wellknown practice in this art. As previously i stated,the saddle invany of the forms referred to may be made integral with or separate from the framing members of the locomotive.

I contemplate the exclusive use of these and other modifications of my invention which come within the scope of my claims.
