The Locomotive Of Today

162 The Tender, Brakes, etc. : Water Tank, Coal Space. The inlet hole and strainer is fitted at the top towards the trailing end, the latter is for the purpose of preventing- the entrance of pieces of wood or other foreign matters into the tank. The feecl water is again passeel through another strainer before it leaves for the injector or pump on the engine. The holes in this last strainer, which is fitted just over the outlet to the cock, are smaller than the smallest part of the injector, so that anything which passes them will not be likely to cause a failure by blocking up its cones or passages. The coal space above is made with a sloping bottom, so that there may be a tendency for the coal to shake forward towards the door, through which the fireman takes it for the fire. A division plate extends up behincl the coal preventing it from getting to the water inlet hole, and also partitioning off a convenient place in which to keep the fireirons and other large tools. The coping round the whole tender gives a finish and hides all the loose tools, further it enables more coal to be carried, and is a safeguard to the men if passing over the top. Where the coal space is insufficient it is usual to carry bars in the form of a fence above the coping to inerease it, this, however, is hardly necessary when the tender is built as in our drawing. Tool cupboards are formed on each side of the tender, a portion of the water space being cut off for this purpose at the front. A hånd brake is fitted, and blocks bear upon each wheel, and for goods engines this is often the only brake provided, but with passenger engines the continuous brake adopted is also either coupled direct to the mechanism, or the steam brake of the engine applies the tender brake simultaneously with that of the train. In the drawing it is shown coupled to the air brake cylinder, but the principle adopted is similar for vaeuum or steam brakes. A, shows an elevation of the tender, the front halt being in section showing the water anel coal spaces, as well as the method of staying the front part of the frame, etc. The back half gives the outward appearance of the whole tender. B is the plan also in half elevation and half section. C is a cross section through the centre line of the middle axle, the left hånd half looking towards the back of the tender, and the right hånd half looking towards the front, both the washplates and stays will be plainly seen as well as the rests for the coal space, which are formed of stout angle irons carried clown to the well of the water tank between the wheels, this well helps to keep the centre of gravity of the tank down, and, especially when the tanks are partly empty, prevents the swaying of the
