KELL, OF RIDLEY PARK, PENNSYLVANIA, ASSIGNOR T GENERAL STEEL CASTINGS CORPORATION, 0F GRANITE CITY, ILLINOIS, A CORPORATION OF DELA- WARE LOCOMOTIVE Application led March 6, 1931.
My invention relates to railway rolling stock and consists in a novel main steam cylinder and steam control valve structure for locomotives and may include thek combination therewith of parts usually assembled with such structure. My invention is particularly applicable to a` structure of this type formed in an integral unit either by-use of a one-piece casting or by welding two or more separately formed parts into an integra-l whole.
My invention contemplates the use of three or more cylinders including the usual steam cylinders at the side of the locomotive and at least one intermediate cylinder. VStructures of this type leave little room for clearance between the different members mentioned and the inclusion of all of these parts, together with exhaust steam passagesin the desirable one-piece integral form has been attended with difficulties arising from the inability of workmen to get at the walls of the different cylinders and chambers which are spaced from the outer portions of the structure.
The main object of my invention is to overcome these diffliculties byV arranging the cylinders, control valves andsteam passages so' that access may be had to the parts hitherto inaccessible without departing from the advantages attending the formation of an integral structure.
In the preferred form of my invention, I form the cylinders and the boiler support integral with the locomotive framing members thereby eecting a maximum of permanent rigidity in the locomotive structure, the attainment of which end isa further object of my present invention.
In the accompanying drawings which illustrate my invention- Figure 1. is a top view of a locomotive cylinder and smoke-box saddle support structure embodying my invention. In this view there is no showing of the lower portions of the structure or of the forwardly and rearwardly extending frame members.

tion. This ligure is taken substantially on the line 2 2 of Figure 3.
Figure 3 is substantially a horizontal section taken on the line 3 3 of Figure 4.
Figure 4 is a vertical transverse section taken on the line 4 4 of Figure 1.
Figure 5 is a bottom view of the rear por'V 1 tion of the structure shown in Figure 1.
Figures 6 and 7 are vertical longitudinal sections taken on the corresponding sectionl der and associated parts with the frame andv indicate the main side members of the framing at 1 and 2, respectively, the same being shown as ofbox section in front of and in back ofthe cylinder structure. Main steam cylinders 3 and 4 are located at thev sides of frame members l and 2 and are integrallyv united therewith by means of transverse walls 5 and 6, and an intermediate main steam cylinder 7 is located abovethe frame members, being supported by suitable webs 8` which constitute extensions of the inner walls of the box-shaped members 1 and 2.
Each of the main steam cylinders is provided with an individual steam control valve chamber 9, 10 and 11, respectively, the valve chambers being mounted on ytheir respective cylinders by suitable webs 12 which form steam'passages between the valves and cylinders. Y
Vertical transverse walls 5 and `6 unite with the cylinders and with the wallsof con-y duits 13 to form the upright members of a boiler support which also comprises the horizontal plate 17 provided with inclined flanges 18 at its sides to which the smoke-box sheets may be secured in the usual manner. lThe upper walls of conduits 13 merge with plate 17 and the discharge members 14 preferably extend throughand project above the top of plate 17. The structure provides suitable passages A, B, C, D and E whereby access may be had to the portions of the walls of cylinders 4 and 7 and chamber 10 which would be inaccessible if the exhaust steam passageway extended directed inwardly with its lower wall merging with the wall of the center cylinder. H
Similarly, exhaust steam passages 19 Vextend upwardly from chamber 9 and then inwardly above and spaced from chamber 11 and curve in a substantially longitudinal direction and also upwardly. They merge with each other at 2O to form a discharge member leading through and projecting above boiler support plate 17 as indicated at 21. The exhaust passages from chamber 11 are'indicated at 22 and they extend upwardly and inwardly beneath the inner portions of passages 19-20 -unitiiigwitheach other in a common discharge member 22a, the lowei` wall of which is spaced from the adjacent l portion of the wall of cylinder 7. This arrangement of passages 19 and 22A provides a space H (see Figure 7) between passages 19 and 22 and chamber 11 andcylinder 7 wherebyiaccess to the adjacent walls of the passages 19 and 22, cha'niberkll, and cylinder 7 may be had for inspection and repairs.
A substantially horizontal web 23 extends between webs 8 intermediate the upper` and lower portions thereof and acylindrical elenient 24, having a vertical axis, is mounted on web 23 and forms a pivotal connection for the engine truck (not shown).
The upwardly and inwardly inclined extensions 25 on webs 8 merge with the wall of center cylinder 7 and` the adjacent parts form a box-like structure beneath the center cylinder and about the upper portion of element 24. An opening F in wall 5 and an opening G in web 23 provide access to the iiiterior of the box-like structure and to the jacent the longitudinal center of the locomotive structure, a steam control chamber located intermediate said'cylinders, and anexhaust steam conduit leading from said side cylinder to thev portion 'of said structure 5 above said center cylinder, the vwall of said conduit being spaced throughout its length from the walls of said center cylinder and chamber.
2. A structure as set forth in claim 1 consisting of an integral unit, there being passageways between said conduit and center cylinder and chamber thereby providing access to the opposing walls of the same.
3. In a locomotive structure, spaced longitudinal frame members having upwardly and inwardly inclined extensions, a main steam cylinder mounted on said extensions, a transverse web between said members, and an element mounted on said web below said cylinder for pivoting a truck to the structure.
4.

5. In alocomotive structure, longitudinal frame members in the form of vertical webs and provided with upwardly extending projections, transverse verticahwalls extending between said webs and extending above the sa-me, a substantially horizontal web below the top of said vertical webs and connecting the same, whereby a box-like structure is formed, a main steam cylinder mounted on the upper portion of said box-like structure, and a truck pivoting element mounted on said horizontal web. i

7. In a locomotive structure, a side cylinder, a steam control chamber above said side cylinder, a center cylinder, an exhaust steam conduit leading from the ends of said chamber towards said center cylinder and curving substantially longitudinally and upwardly above said center cylinder, said conduit being spaced throughout its length from said center. cylinder, there being substantial openings between the end portions of said conduit and the space between said conduit and center cylinder being open to the outside of the structure through said openings to permit access to the opposing inside walls of the same for cleaning and inspection purposes.
