The side walls 3 of the box-like member form the inner walls of the side members 1 and 4a in front of the cylinders.

It will also be understood that the main longitudinal force transmitting member may comprise two spaced members having vertical webs or a single member having av vertical web and laterally extending flanges.

The main steam cylinders are indicated at 5 and 6 and each is provided with a `corresponding steam supply valve, the chamber for which is shown at 7 and 8, respectively. These cylinders and valve chambers are supported from the main member by a substantially box-like saddle structure comprising front and rear walls 9 `and 10, respectively, and horizontal top and bottom webs 1 1 and 12, respectively, which are substantially in line with the boxwalls 1 and 2.l Walls 9 and 10 extend upwardly above the level ofthe center member and ,above the Ysupply valve chambers and are connected by upright walls 14, all of these walls forming the sides of a box which has anV arcuate top plate'15 on which the smoke-box of the boiler rests. A depression 16 on each side of the saddle and an elevated flange v16a cooperate to form a horizontal shelf which is provided with an opening to the live steam passageway 17- which leadsV direct to the adjacent steam valve chamber The inlet end of this passageway is circular in cross section and shelf 16-1 6a, surroundin the inlet end, forms a mounting for apipe tting. i Exhaust steam passages 18 extendinwardlyand upwardly from the ends of the valve chamber and converge towards each other, theinwalls'merging near the center of the structure to form a support for vthe central portion of the top plate on vwhichthe usual exhaust. nozzle will be mounted. i

` The arrangement of the steamfpas'sageways as described and illustrated provides suba stantial spaces S between each live steam passageway and the adjacent exhaustlsteam pas,- sageways whereby the side walls of these passageways arev accessible for inspection and for any necessary repairs. These spaces also provide access to the valve chamber inner side which faces towards the center line lof thelocomotive. In order to permit similar access to the corresponding side of the main steam cylinder and at the same timepermit access to the bottom walls ,of the steam passageways 17y and-l8 we provide substantial openingsV A `and B in the horizontal webs 11 and 12 which extend outwardly from the main underframe member 1-2-3. Y

Aportion of the top wall 1 ofthe main member is inclined upwardly, as indicated at 20, abreast of the cylinders.. This inclined,V

portion 20 is'rei'nforced by a suitable flange 21 projecting downwardly therefrom. similar reinforcing flange 22 substantially surrounds the opening A in web 11 and a corresponding flange 23 is provided around the opening B in thepwebV 12,.V

Restricted parts of web 11 and wall 1 form the bottom of the exhaust steam passages 18 adjacent to their convergence with each other.

Similarly, walls 9 land "10. are provided with openings C to facilitate vaccess to the inner walLof the cylinder.v

The openings S, A and B are large enough for a man to get down into the casting behind the valve chamber'and steam cylinder and near the'bottom'wall of the live steam passage ,for closing any leaks or otherwise working on the adjacent walls of the structure. lVithsuch Vwork in mind, it will be readily vunderstood that the narrowing of the steam passagewaysl' and 18is of substantial advantage because it makes possible larger openings. To the same end, weY have terminated each Vsupplementary lside member 4, eta near the ends of the cylinder and have provided arcuate connections 24 between the supplementary side lmembers and the side of the cylinder wherebythe cylinder walls form, in effect, a continuation of the supplementary sidemember through the, saddle portionwithoutA unduly restricting the space behind the cylindersas `would be done if the vertical walls of members 4, 4a continued through the saddle structure. Hori zontal webs11 and 12 lcontribute to this feature of our construction.

Similar opening`sDE and F` are provided in theY front wall 9 to facilitate molding andV inspection. Openings G and H are provided in the rear wall 10 furthe s ame `purposes. Openings J and K are provided in the top plate 15 and openingsl L and M are provided in thebottom wall 2 of the main member, all these openings being provided for molding andinspection purposes.

The metal surrounding openings D,VE, F, G, H, J, K and L is finished by counter-borA ingor other machining and cover plates P are applied' thereto, preferably by welding, after thebed is finished. This prevents access of cold air to the walls of the steam passageways and'tothe inner sides of the cylinders andl steam, valve chambers and reduces theamountof condensation which wouldotherwise occur in the steam filled compartments of the device. `The openings S are closed by means of the usual jacket around the cylinder' and steam chest.

Summarizing the features describedy above, it will be seen that we have provided a locomotive bed having a main box-like backbone member extending from the front of the bed through the cylinder: and smoke-box saddle portion of the locomotive tothe rear wall of the latter andfhave provided, in an integral structure, cylinders, valvechambers, live llU llo
