MARIS STEAM PIPE FOR SIMPLEARTICULATED LOCOMOTIVES Filed May }.O, 1929 2 Sheets-Sheet 2 Patented May 13, 1930 UNITED STATES PATENT GFFCE STEAM PIPE FOR SIMPLE ARTICULATED LOCOMOTIVES Application filed May 10, 1929. Serial N0. 362,036.
My invention relates to certain improvements in the high pressure steam supply pipes of a simple Mallet7 type locomotive.
The object of my invention is to improve the flexible steam pipe arrangement leading from the rear fixed cylinder saddle to the forward flexible cylinder saddle, so as to prevent leakage at the joints and to relieve the weight of the heavy supply pipes which unlO der present construction crush the packing at the joints, and to obviate the bending of the steam supply pipe between joints.
In the accompanying drawing:
Fig. 1 is a side view of sufficient of a high pressure simple locomotive of the Mallet type to illustrate my invention, a ballandsocket connection being in section;
Fig. 2 is a plan view;
Fig. 3 is an enlarged sectional view of the steam supply pipe, showing the supported ball-and-socket joint and the slip joints;
Fig. 4 is a sectional view on the line 4 4, Fig. 3; and
Fig. 5 is a modification.
The drawing illustrates the forward end of a locomotive in outline, a number of parts being omitted in order to more clearly illustrate my invention.
1 is the rear frame of the locomotive, on
which the boiler 2 is rigidly mounted. This forward end of the boiler overhangs the front frame 3 as in the ordinary Mallet-locomotive. The two frames 1 and 3 are connected by the link 4 connected to the rear frame by a universal joint 5.
The rear cylinder structure is secured to the forward end of the rear frame 1, and in the present instance consists of the two separate cylinder castings 6 and a central saddle 7 which forms a support for the boiler 2.
The cylinder castings contain the high pressure cylinders 8 and the steam chests 9. In some instances, the cylinder structure may be made in one piece as in Fig. 5, or in two sections. The form of the cylinder structure is no part of the present invention.
Steam is taken from the boiler in the present instance through a dry pipe 10, superheater header and throttle valve structure 11, and side steam pipes 12-12 which are v each pipe located within the smoke boX of the boiler. Each pipe 12 is attached to an elbow connection 13 on the outside of the boiler. The elbows are connected to pipes 14 extending to the rear cylinder structure. At this point is coupled to a T connection 15. The branch 16 of each T connection is coupled to the steam supply pipe of the cylinders 6 which lead to the valve chests 9. The other branch of each T is connected to a U-shaped Go pipe 17 leading to the Y-shaped passages 18 in the central saddle 7 which communicate through a ball joint 19 with a pipe 20 located between the forward frame of the locomotive. The details of the ball joint are shown in Fig. 3, but the same may be modified without departing from the main features of the invention.
The ball 21 of the joint is on the pipe 20, and the opposite end of the pipe extends through a slip joint 22. The housing 23 of this joint forms an integral part of a ball 24. On the pipe 2O is a wear sleeve 25. The pipe 20 extends through the ball 24 as shown in Fig. 3. rlhe ball 24 is mounted in a socket 26 which is rigidly coupled to a pipe 27 which in turn extends into a slip joint 28 in the saddle 29 of the front cylinder structure.
AThe socket 26, in which is the ball 24, is rigidly supported by a cross-tie 30 which is 80 secured to the side frames 3-3 as shown in Fig. 4. The socket 26 has, in the present instance, an integral base 31 which is bolted to the cross-tie 30, and the cross-tie has side extensions 32 which are secured to the side frames. Thus the pipe 27 is secured to the support socket 26 and can slide longitudinally in the slip joint 28, but it has no fiexing movement. rl`he pipe 20 is supported by the fixed socket 26 at oneend and the socket 19 in the saddle 7 at the opposite end, and while it is firmly supported at both ends it will accommodate itself to the movements of the locomotive frames.
The arrangement of the steam pipes leading from the smoke-boX end of the boiler to the cylinder structure on the rear frame forms no part of my invention, but is claimed in the companionv application filed on the 100' 10th day of May, 1929, under Serial No. 362,089, in the name of Henry K. Harwich.
I claim l. The combination in a high pressure simple Mallet locomotive, of a rear frame, and a front :trame coupled to the rear frame; a cylinder structure at the forward end of each frame; a boiler mounted on the rear frame and overhanging the :front frame; a live i pipe extending from the smoke bof; and of the boiler to the rear cylinder structure; a live steam pipe made in two sections extending from the rear cylinder structure to the front cylinder structure; a ball-and-soclret connection for the two sections of the pipe section 5 and means for supporting said ball-andsoclet connection.
2. The combination in a high pressure simple Mallet locomotive, of a rear trame, and a front frame coupled to the rear frame; a boiler carried by the rear frame and overhanging the front trame; a cylinder structure fixed to the rear frame; a cylinder structure on the forward Jrame; a socket structure supported by the front frame; a live steam pipe attached to the socket structure and eX- tending to the forward cylinder structure of the front frame; a socket at the cylinder structure of the rear frame; and a live steam pipe having a ball at each end adapted to the said sockets.
3. The combination in a high pressure simple Mallet locomotive7 of a rear frame and a front frame coupled together; a cylinder structure at the forward end of the rear frame; a cylinder structure at the forward end ot' the front frame; a live steam pipe extending from the rear cylinder to the front cylinder structure, said pipe being made in two sections, the section nearest the rear cylinder structure being' short and connected to the forward section of the pipe by a ball-andsocket joint; and a cross-tie secured to the side frames of the locomotive and supporting the ball-and-socket joint between the two sections of the pipe.
et. The combination in a high pressure simple Mallet locomotive, of a rear frame, and a front :trame coupled to the rear frame; a cylinder structure at the front end of the rear frame and having a live steam supply passage therein; a cylinder structure at the forward end of the front frame and having a steam passage communicating with the cylinders thereof; a cross-tie secured to the side members of the front frame some distance from the forward cylinder of said frame; a socket structure rigidly secured to the crosstie; a live steam pipe leading from the socket structure to the steam passage in the forward cylinder structure oi' said front frame; a socket in the cylinder structure of the rear frame; and a pipe connecting the steam passage in the cylinder structure of the rear frame with the pipe leading to the cylinder JAR/L35 C.
