Another form of geared engine for screw propulsion, was the steeple type introduced in the earlier Inman steamers. Considerable trouble was experienced in all these engines with the gearing, owing to the heavy wear, which required constant renewal of the wooden teeth, and it was eventually found that they gave more trouble than the engines connected direct on to the screw-shaft. Section at XY Looking Forward. THREE CYLINDER COMPOUND ENGINES, MONTANA AND DAKOTA. After the engines for screw machinery were arranged so as to be connected direct to the propeller-shaft, many types came into vogue, each line favouring its own form, the Inman adopting the horizontal trunk engine, the Cunard the inverted direct-acting, followed afterwards by the Guion and other lines. The Guion Line in its first vessels adopted the inverted direct-acting engine, but afterwards changed, in the Wyoming and Wisconsin, to the type having one vertical cylinder and one horizontal with trunk, both working on the same crank.
