BOILER FOR ARTICULATED LOCOMOTIVES.

Specification of Letters Patent.

Patented Oct. 7, 1913.

Application filed July 28, 1910. l Serial No. 574,300.

To all whom t may concern:

Be it known that I, WILLIAM J. LEIGHTY, a citizen of the United States, and resident of Topeka, in the county of Shawnee and State of Kansas, have invented a certain new and useful Improvement in Boilers for Articulated Locomotives, of which the following is a description, reference being had to the accompanying drawings, which form a part of my specification.

My invention relates to a flexible joint for boilers on articulated locomotives; the object being to provide a flexible joint whereby the two part-s of the boiler of an articulated type of loco-motive arevconnected together, e'. e., a locomotive consisting of two independent sets of mechanism attached to two frames which are hinged or coupled together, thusallowing a long wheel base, but providing enough flexibility for the locomotives to pass around curves.

The object of my invention is to provide means whereby the two parts of the boiler may be rigidly attached to the two independent frames of the locomotive, permitting the two parts of the boiler to follow the relative movement of the framesv to which they are att-ached.

A further object of my invention is to provide space for superheating means for the two locomotives and a simple steam pipe arrangement with the least possible number of flexible joints in the steam pipes.

Another object of my invention is to provide as large a flexible joint as possible in order to keep the temperature of the walls as low as possible and thus allow more favorable conditions of the lubrication of the joints.

A still further object of my invention is to provide a joint which is readily separable,

allowing the two sections of the locomotive to be easily parted in order to make repairs on the fines and the like.

The advantages of my invention will be more clearly understood from the following detailed description of the accompanying drawings, wherein Figure l is a side elevation of a locomotive equipped with my improved flexible joint. Fig. 2 is a longitudinal sectional view of the flexible joint of the boiler shown on an enlarged scale. Fig. 8 is a longitudinal sectional view illustrating a modified form of the flexible joint of the boiler. Fig. 4C is a longitudinal sectional view of another modified form of the flexible joint of the boiler.

In Fig. l I have illustrated the flexible joint applied to a locomotive consisting of two ten coupled units, in which l represents the rear or lire-box end of the boiler, which consists of the boiler proper, z'. e., the part that is used for generating the steam; while the front part 2 of the boiler constitutes a feed-water heater 3, and a smoke box 4f. rIhese two parts l and 2 are connected by the flexible joint 5, see Fig. 1, which forms the intermediate part of the boiler shell and surrounds that portion of the boiler shell which I will designate as the superheating combustion chamber which is occupied by the superheaters 6 and 7 which supply the engines for the rear and forward sets of driving mechanism, respectively. The boiler tfeed-water is supplied to the feed-water heater 3 by the injector pipes 8, see Fig. l, leading from the injectors. The injector pipes 8 are provided with flexible means 9 which allow the pipes to articulate with the parts of the boiler and frame. The feedwater is conducted from the feed-water heater 3 to the boiler l by the pipes 10, which pipes are also provided with the flexible means 1l for the same purpose as that mentioned in connection with the flexible means 9 of pipes 8. The front end of the rear part l of the boiler is rigidly secured to the frame 12 by the saddle 13; while the rear end of the forward part 2 of the boiler is rigidly secured to the frame let by the saddle l5. The steam distribution indicated in Fig. 1 applies to an articulated locomotive in which the rear part is the high pressure engine, while the forward part is the low pressure engine. The steam is delivered to the high pressure superheater 6, see Fig. l, through the dry pipe 15a, shown in dotted lines, and is conducted from the superheater by the steam pipe 16 to the high pressure cylinders A. The steam is conducted from the high pressure cylinders A to the saddle l5 through the 'flexible steam pipe 17 which, in my improved construction, is the only fiexible steam pipe required in the entire locomotive.

Cit

shown riveted into the boiler shell 20h. The forward end of the dry pipe l5a is shown in its relation to the front lue sheet of the boiler; the front end of the boiler tubes are also shown at 65, secured to the flue sheet 64. ln smaller articulated locomotives or in those where the vertical movement required of the flexible joint is very slight, the modiiication shown in F ig. 4l and just described, will be found adequate to suit the conditions to which the joint may be subjected.

By having the flexible joint as near the diameter or' the boiler as possible, the gases of combustion will have ample room to pass through and thus impart as little heatto the walls ot the joint, as possible, and in this manner keep the ten'iperature of the walls ot' the joint comparatively low, and thus aid the lubrication of the joint.

The object of my invention is to make a practicable and economical construction that will simplify the construction of the rigid boilers such as are now in use on articulated locomotives and are supported onk the front or movable trame by sliding supports. Such a construction necessitates the use of complicated steam pipes provided with numerous liexible steam joints. With my improved construction the number oit flexible steam joints are reduced to a minimum; and with the front part of the boiler rigidly secured to the frame and made to articulate with it, permits the center of gravity of the boiler to remain at all times in the same relation to the trames and driving mechanism or the locomotive.

l have shown and described what l believe to be the simplest form of my invention, but the same may be altered in a number of details without departing from the spirit of my invention, and l do not wish to be understood, therefore, as limiting myself to the exact construction shown and described, but
