Exhibit : —One Compound Tractor.
An entirely new method of lubricating the working parts of the engine has been adopted by Clayton and Shuttleworth, Limited, of Lincoln, on its steam tractors which are exhibited at Olympia. This new feature bids fair still further to increase the popularity af this little machine. Hitherto, it has been necessary to stop the engine in order to oil the various parts, but, with the new arrangement, a diagram ot which we reproduce herewith, the lubrication goes on continuously. The advantage of being able to effect this without leaving the foot plate is obvious, and will commend itself to every practical man.
Another feature in the design of this company's tractor is the ingenious manner in which the spring mounting is carried out. One of our illustrations, which represents a section through the back axle, second-motion shaft, and crankshaft, clearly shows how the springing is arranged. The after end of the tractor is supported from the back axle, by means of helical springs of rectangular-section steel wire, which permit of the axle's rising, relatively to the horn plates, for a short distance; as the axle, and consequently the final-drive wheel (A), rises, the pinion (B) also rises a like amount. This movement is ensured by reason of the linking together of the axle and the second-motion shaft by the link (C). The other end of the secondmotion shaft is universally jointed to the hollow huh of the change-speed wheels (D and E), at the point (F), All ' the gear wheels are, therefore, always in correct mesh. The machine which is shown by this company has been purchased by Messrs. J. Honour and Son, contractors, of Tring. The Kirkstall Forge Company, of Leeds, is also showing one of this make of tractor on stand No. 54 in the Main Hall. Amongst the many complimentary letters which have been received by Clayton and Shuttleworth, the following extracts are typical ones :—The Devon Trading Co., Limited, in a letter dated January loth, 1907, stated : " Our haulage system is working well, and we do not injure the lanes. We can take in eight tons of lime at one time." This company wrote again on July 22nd, 1907: " INe formerly used six horses to do what your engine is doing now. Without going closely into details, the corn for them used to cost us is. per week per horse, being ,-L4 los. per week for the six horses, or L;234 per year. The cost for engine is just under 4s. 6d. per day, being £t 75. per week, or £70 per year, as against £234 for corn. Everything else is in favour of the engine," Among the numerous purchasers of this tractor may be mentioned the following :—The Devon Trading Co., Limited, Axminster; Mr. Edward Kirby, carting contractor, Hull; Mr. George W. Almond, brick manufacturer, Burnham, Bucks (two); Messrs, Wright and Pankhurst, the Furniture Repository, Rye ; Messrs. G. Thomas and Son, house breakers, Kingston Hill, London ; Mr. J.
