The frames are 6 in. wide, spaced 41 in. between centers,each frame being cast in one piece with a single front railto which the cylinders are bolted. The transverse bracingcalls for special attention. A most substantial steel casting,placed just back of the cylinders, extends the full length ofthe leading driving pedestals and serves as a fulcrum for thedriving brake shaft. The guide yoke crosstie is also of caststeel and it is extended back sufficiently far to brace the sec- 419 420 RAILWAY MECHANICAL ENGINEER Vol. 95, No. 7.

This serves as a support for the driving brake cylinders, one of which, because of la< kof room, is placed in a horizontal, and the otht-r in a verticalposition. The two brake shaft arms are placed at right an-gles to each other, the horizontal cylinder being connected to
