Which of the following most accurately describes the problem?

TORE and more the fact is being 11.1.recognized that in a tractor. the farmer has not only a machine to pull his ploughs and to do the haulage work, but a portable power plant which can be applied to a very wide range of useful purposes, this portable power feature making the purchase of a tractor an economic proposition to other than farmers. All, indeed, who have any haulage work to which the tractor can he applied find that the increased usefulness of the tractor, by reason of this portable power feature, renders the purchase of such a machine a commercial proposition to them in their business.

The Fordson tractor has a larger sale than any other -tractor in the world, and in this machine this feature is recognized by the provision of a special gear on which can be mounted a belt pulley ; but, as every owner , does not necessarily require this equipment, the pulley outfit is sold as an extra.

As is so frequently the case in America, special power equipments, as alternatives to the_ standard Ford belt pulley outfit, are offered, with certain claimed advantages of their. own, and in this connection one which has alarge sale is known as the Smith unit clutch pulley, of which an illustration is =chided, the market for which, of course, is found amongst the owners of and dealers in Fordson tractors.

As will be teen from the illustration, the Smith unit consists of a driving pulley mounted at one end of a tubular housing support and with a spiral bevel gear of chrome nickel steels-supported by a hall bearing and integral with a short spline(' drive shaft at the other.

The belt pulle_y is also furnished with a similar short-splined drive shaft and the two shafts are slidably connectable by a splined sleeve, moved longitudinally by a suitable lever.A pull of the lever slides the sleeve enclosing the idling pulley shaft on to the splined live-drive shaft, locking the two firmly together, to secure rigid power transmission. But it does not change the pulley speed. Moving the lever the other way slides the sleeve back and releases the idling shaft, the movement being quick, positive and .-foolproof, with no chance of jarring into or out of mesh, no matter how great the vibration.

The housing of this mechanism is both dust-tight and oil-tight. The inner spiral bevel genii, which is always in mesh, hears the same ratio to the main crankdrive gear as the standard Fordson rigid mounted pulley. A special sprocket may be fitted to the shaft in place of the pulley for industrial uses, such as operating chain-driven winches, hoists, etc., if desired.

With this equipment the Fordson owner can operate his machine for belt purposes in the most convenient manner. With it he can stop and start auxiliary machinery instantly by shifting the lever which controls the movement of the spline-shaft collar. He has not to throw a belt on or off a revolving pulley, or to stop and start the tractor motor at frequent intervals, and the danger of injury during these operations is eliminated, whilst the tractor is much easier to adjust into belt position, as the pulley can be thrown into a neutral position and the tractor backed into the belt under its own power.

It is stated that last year in America the sales of this unit averaged • one to every five Fordsons sold, and it is also stated that in the foseign market over 400' were sold in Italy. The price is 12 guineas.
