The interest which attachesitself to Ibis engine lies entirely in its and propor-tions, which are given in resuiiic iu the ainiexed table. Theconstruction olVers no esi)ecial jieeuliarity, and it is sinular tothat of ordinary engines, types 2, 28 and 2i). It is providedwith a track brake, which is operated by hand in some locomo-tives, the maniiiuhition of the brake being controlled by a steamcylinder in which it is possible to modify anil vary the intimately with the products of cond)Us-tion, quickly and easily communicates itsmomentumto them, thus readily drivingthem out of the stack. The shell is .(i in. The combination of the details of this brakeoffers this peculiarity, that it frees the suspen-sion sjirings of the engine from the reactions ofthe brake upon the riul, and while it is in op-eration they do not lose their load or their play.
