CYLINDER SADDLE.

Application filed May 26,

The obj t of'our invention is to makea cylinder saddle containing three cylinders and their valve-chests in asingle cast metal structure.

, the locomotive shown by dotted lines in The drawings illustrate a construction in which the three cylinders are high pressure 7 v the steam-chest 8 of the centrally located cylinders, but itwill be understood that the invention can be applied to a three-cylinder structure in which two, of the cylinders are low pressure cylinders and the other cylinder a high pressure cylinder.

In the accompanying drawings: Fig. 1 is an end, view of a locomotive- 1v inder saddle, the. heads of the cylinders and. valve-chests being removed to avoid con- 2 is a plan View;

Fig. 6 is a sectional C-G, Fig. 1;

Fig. 7 is a sectional elevation on the line D-D, Fig. 1;

.Fig. 8 is a sectional elevation on the line EE, Fig. 1;

Fig. 9 is a transverse sectional view on the line FF, Fig. 5; v

Fig. 10 is a transverse sectional view on the line G-G, Fig. 5; and

Fig. 11 is a transverse sectional view on the line HH, Fig. 6.

The cylinder saddle 1 is made in a single casting and has flanges 2-2 which are rigidly secured to the longitudinal frames 33 of elevation on the line Figs. 1 and 4. I

The cylinder saddle has three

cylinders

4, 4 and 5. The cylinders H are on either side of the structure and overhang the locomotive frames 3-3 as shown in Fig. 1.

The cylinder 5 is centrally located, and in the present instance is inclined as'shown in, Fig. 8, while the side cylinders .t4 are horizontal. This arrangement of the cylinders allows the connecting rod of the central cylinder to clear the mechanism and to be coupled directly withthe centrally lothe smoke-box of the. locomotive 1927.

cated crank on one of the driving axles of the locomotive.

6+6 are the: inlet passages for steam connecting directly with the steam-chests 7-7 of the 7 two I cylinders 4-4, respectively. The inlet passage 6 also communicates with cylinder 5 through a passage 9 as shown in Fig, 4..

sage 1-2 through passages 1313*.

The main exhaust passage 12. extends partlyaround the central cylinder 5, and its outer end communicates with thev nozzle in (not shown). The end of the exhaust passage extends above the, curved saddles 15 of the cylinder structures and is: well within the smoke -box. of the. locomotive.

The. steam-chest 8: o;f the central cylinder communicates with said cylinder through passages 16, Figs. 5 and 9, and with the main exhaust passage 12 through .a passage 17, Fig. 7.

In the cylinders are the usual bushings 18 and in the steam chests are the usual twopart perforated bushings 19.

By the above construction, the three cylinders and their steam chests. are formed in a comparatively simple casting, in which the passages are short and direct and the main exhaust passage extends under the central cylinder and around one side thereof to the nozzle opening at the upper portion of the casting.

The steam inlet passages are directly above the steam chests of the outside cylinders and are connected to outside pipes lead-.

directly with the several valve chests; and an exhaust passage partly surrounding the central cylinder and communicating with the several valve chests.

2. A cylinder saddle for locomotives made in a single casting having flanges arranged to be secured to the side frames of the locoeach cylinder; passages forming communication between the valve chests and the cylinders; a steam inlet passage at each side of the structure communicating directly with the valve chests of the outside cylinders; a passage connecting one of said steam inlet passages with the valve chest of the central cylinder; a main exhaust passage extending under the central cylinder and partly around said cylinder and opened at a point above said cylinder; and passages connecting the several valve chests with the main exhaust passage.

3. A cylinder saddle for locomotives made in a single casting and having means by which it is secured to the side frames of the locomotive; an inclined central cylinder; a side cylinder overhanging each side of the frames of the locomotive; steam chests for the side cylinders directly above said cylin-' ders and communicating therewith; a steam chest for the central cylinder located between one of the side steam chests and the central cylinder and communicating with said cylinder; steam inlet ports directly above the side valve chests and communiseveral steam chests with said main exhaust passage.

4:. A cylinder saddle for locomotives made in a single casting and having flanges arranged to be secured to the side frames of the locomotive; a curved saddle section on which the boiler is mounted, said structure having an inclined central cylinder and overhanging side cylinders; a cylindrical valve chest for each of said cylinders; pas-- sages forming a communication between the valve chests and their respectlve cylinders;

two steam inlet passages, one at each side of the cylinder structure beyond the curved saddle and arranged to be connected to outside steam supply pipes and communicating with the valve chests of said cylinders; a

passage connecting one of said valve chests with the valve chest of the central cylinder;

an exhaust passage extending under the in clined central cylinder and terminatingin a horizontal section above the curved saddle portion; and an exhaust passage forming communication between the several valve chests and the main exhaust passage.
