This arrange-ment provides great accessibility for any attention thatthe booster engine may need. Referring to the line engraving the attachments, shownat the side of the cylinder are cylinders for the operationof the cylinder cocks.

This is accomplished by means of the sphericaljoint shown in section. This is located at the transversecenter and the bearing proper consists of the two parts 3and 4. The lower convex portion 3 is regidly attachedto the truck, while the upjx^r ]iart. 4. is fastened to theengine bed. The tvv(j are held together by the holt tension on this Ixilt is regulated by a helical springso that it can yield as the upi>er portion of the sphericaljoint moves over the lower.
