LOCOMOTIVE CYLINDER SADDLE.
Application filed July 5,
cylinders thereof to the boiler and frame members, which shall present the advantages of reduction of structural cost, and of finished Weight, within the limits of sufiicient strength, and symmetrical disposition of constituent members.
The improvement claimed is hereinafter fully set forth. l
In the accompanying drawing: Figure 1 is a side view, in elevation, of a saddle for a three cylinder locomotive engine, illustrating an embodiment of my invention; Fig. 2, a front view, in elevation, of the same; Fig. 3,' a horizontal section, on the line a a of Fig. 2; Fig. 4, a vertical sec' tion, -on the line b b of Fig. 2; Fig. 5, ,a side view, in elevation, of a. saddle showing a structural modification; Fig. 6, a front view, in elevation, of the same; land. Fig. 7, a vertical section, on the line c c of Fig. 6.
In the practice ofv my invention, referring. descriptively to the specific embodiinent thereof which is herein exemplified, and first to Figs. 1 to 4 inclusive, the saddle comprises a body, 1, having bottom flanges, l, adapted to fit against the side members, A A, of a locomotlve frame, and a smoke box seat, l", at its top, concavely curved, on the radiusY of the smoke box, B, of a locomotive boiler, which the saddle is designed to support, and to which, in service, it is connected in the usual manner.
A middle cylinder, 2, `and a distribution valve chest, 3, therefor; two side cylinders, 2a, 2b; and distribution valve chests, 3a, 3, for said cylinders, respectively, are cast integral with the body, 1, of the saddle, the side cylinders being located symmetrically in the body, relatively to its middle vertical plane, with which they are parallel.
Steam from the boiler is conveyed to all three distribution valvey chests through steam supply pipes, C, C, extending outwardly from the smoke box, in the present standar-d manner, said pipes being connected 1924. serial No'. 724,534.
to short supply nozzles, 4a, 4", also integral with the body of the saddle, and projecting upwardly therefrom, above the valve chests, 3, 3b, of the side cylinders. The supply nozzles communicate with the ends ofl a transversely extending steam supply conduit, 4, cored in the body, said conduit being continuously in open communication with the middle portion of each of thcdistribution valve chests, 3, 3a and 3*. EX- haust passages, 5, 5, leadv from the end port-ions of the valve chests, 3, 3b, of the side cylinders to the smoke box seat, l, andexhaust passages, 5, lead from the end portions of the valve chest, 3, of the middle cylinder, to the smoke box seat. Exhaust pipes land nozzles, of any suitable and preferred construction, which do not form part 'of my present invention, are, inservice, connected to the ends of the exhaust passages.
The bottom of the body of the saddle is machined, to form plane faces thereon, which abut against the side members, A, A, of the locomotive frame, ,to which the saddle is rigidly attached, by bolts, 6. The body is preferably recessed at its bottom, to'
fit over the frame members, as shown, and has strengthening flanges, 1, adjoining them, on its front and rear sides.
The modification shown in Figs. 4 to inclusive, differs from the construction hereinabove described, in the minor structural particulars that the middle cylinder, 2, is downwardly and rearwardly inclined, instead of being disposed horizontally as in the construction first described, and its valve chest, 3, is located on one side, instead of above it. As a result of such relative disposition of the middle cylinder and valve chest, the 'transverse ysteam supply conduit, 4, may, as shown, extend only between the valve chest of one of the side cylinders, and the valve chest, 3, of the middle cylinder. The bottom of the body of the saddle, in this modified form abuts only on the top and outer sides of the frame members, instead of being recessed to fit over them', as in the construction first described.
It will be recognized by those familiar with locomotive construction and operation, that the cylinder saddle herein set forth, desirably complies; with the requirements of a structure for supporting the cylinders and boiler of a three cylinder locomotive and connecting them to the frame members.
and the distribution valve chests, in an integral'casting, reduces, to a substantial eX- tent, the weight and the cost of manufacture of the structure, by eliminating the machine work and bolting required in the two piece and three piece saddles of the present designs and also a simpler and more direct disposition of steam and exhaust passages, is render-ed practicable.
I claim. as my invention and desire to secure by Letters Patent:
l. A cylinder saddle for three cylinder locomotives, comprising a body, having plane races at its bottom, adapted to abut against frame members; a middle cylinder and two side cylinders, disposed symmetrically in the body and integra-l therewith; and distribution valve chests, integral with the body, each adjoining one of the cylinders.
2. A cylinder saddle for three cylinder locomotives, comprising a body, having plane faces at its bottom, adapted to abut against frame members; an inclined middle cylinder and two horizontal side cylinders, all
integral with the body; a distribution valve the side cylinders, adapted to receive boiler f steam; and a steam supply conduit, connecting one of said nozzles with the distribution valve chest of the middle cylinder.
3. A cylinder saddle for three cylinder locomotives, comprising a body, having plane faces at its bottom, adapted to abut against frame members; an inclined middle cylinder and two horizontal side cylinders, all integral with the body; a distribution valve chest at one side of the middle cylinder, and a distribution valve chest above each of the side cylinders; nozzles on the valve chests of the side cylinders, adapted to receive boiler steam; and a steam supply conduit, extending transversely and downwardly from one of said nozzles, and connecting said nozzle with the distribution valve chest of the middle cylinder.
