Messrs. Clayton and Shuttleworth show a traction engine, which is in many respects new. The general design is, as will be seen from our illustration, very similar to that which they have shown for the last two years, and has already been fully described in our columns. But the new engine, instead of one has two cylinders, and the crankshaft is made on Worsdell's system, with circular discs instead of webs. Mr. Worsdell has used these with great success on locomotives, and they ought to answer equally well on traction engines. They are cut out of the solid. The thinness of web thus secured enables the engine to be kept narrow. Messrs. Clayton and Shuttleworth maintain that for hauling purposes the double-cylinder engine is far and away the best for handiness and power. In the engine at Chester, the main idea has been to use the same driving gear and road wheels as for their single engines, and maintaining the same width between the frames, and no doubt Mr. Tyrrell, the designer, has succeeded in producing a very symmetrical and accessible engine. To economize room the crankshaft is, as we have said, of Worsdell’s disc pattern, which gives a strong crank with a thin web, and is also cheap to manufacture, all the work being done in the lathe. The stop valve and reversing levers, brake, and clutch levers, handles and levers for cylinder taps, steam blower, and ash-pan damper, are all within easy reach of driver, in accordance with all good locomotive practice. The roomy footplate with its ready means of access and facilities for firing are also good points. As a traction engine—which never can be made either graceful or handsome—we venture to think this one will, in the eyes of a practical engineer, receive a favourable verdict for symmetry and fitness for hard work, for which it is designed. The engine is fitted with Tyrrell and Deed‘s patent governor, also with chain steerage, which is more suitable than the rack steerage for some districts. The firm, we believe, now make the two types of steerage interchangeable, so whichever is preferred can be supplied. The fact that the engine is made by Messrs. Clayton and Shuttleworth is sufficient guarantee that the workmanship is admirable. The footplate is much larger and more convenient than usual, as may be gathered from the illustration on page 540, prepared from a photograph, which, however, as is the manner of photographs, is exaggerated in perspective.
