( )ther ramifications inthe engineering art—locomotives, stationary steam engines andturbines likewise—have invariably weathered the trials of the de-velopment stage. Fig. 6 practically coincides with Herr Drawesconclusion, omitting the separation of the cylinder at the cen-ter, which is allowable in small frames to which the illustrationapplies. This feature is, however, necessary in large cylinders. The cylinders are supported through the main frame and dis-tance piece, and thereby relieved of any external load—anotherimportant count. Inlet and exhaust valves are located at eachcombustion chamber, diametrically opposite, allowing the great-est latitude for s
