Not illustrated. 1894 Excerpt: ...Each have merits for particular positions. Thus the latter is very narrow and long in proportion, and its work is all done on one crank. It is in high favour in north country factories, and is sometimes known as the Lancashire pattern. The " coupled " is suited to bayonet and other patterns, and most large high-class engines are made of this form. It has two cranks, and when made condensing the air-pump is laid out on a foundation behind the low-pressure cylinder. For flour-mill work it is very suitable, and indeed for all general purposes where space for it can be found. High-speed Coupled Compounds, Suited For Direct Driving Of Dynamos And Centrifugals. A special class of these compound engines has been developed by the English agricultural engineers, which is arranged in a wrought-iron framework, and is in all respects similar to the engines supplied by them in the semiportable form. These may be described as--Moderate Speed Coupled Compound Engines, Suited For Long Runs, With Compact And Close Framings Of "semi-portable Type." Large High-Class Coupled Compounds.--Where engines are to develop hundreds of indicated horse-powers, the conditions demand close calculation in each case; therefore, the lists prepared are not carried beyond the limit of 250 horse-power. And, without question, condensation should be brought into consideration and, if possible, adopted. In dealing with the "Corliss" engine in the preceding chapter, information was given as to the usual sizes in arranging that type of engine as a compound. While large power engines of such high-class demand very careful estimates of cost to suit each case, the following costs of the smaller sizes will be a relative guide. Tandem Compound Engines are commonly known in E...
