gineer to the fireman, when necessary.
The two sections of the boiler are entirely independent as regards' the steam There is no steam connection be- 'tween the two sections of the boiler, but the products of `combustion pass through the tubes of each section into the stack and these tubes may be of different sizes, as shown in the drawings, depending somewhat uponthe character of the fuel used.
' In order to create a sutlicient draft in the boiler, I provide a fan 25, driven by a` motor 26, in the present instance, of the steam yturbine' type, so as to cause a draft through vthe tubes,.the fan delivering air to the stack, and I preferably arrange a diaphragm Q7 directly back of the fan so as to cause all ofthe products of combustion to be Vdrawn to the intake of the fan. I preferably mount the fan and the engine on rails 28 so that when the cap 29 the end of the smoke box is removed, the motor and the fan can be' withdrawn, and the diaphragm removed so that the tubes of the forward section can be withdrawn through the forward end of .the section, although in some instances it may not be necessary to remove the diaphragmpin order to remove the tubes that are in line with the opening therein. rl`he steam turbine can be regulated by hand` or automatically, to maintain the necessary draft'in the boiler` w I have not shown a. superheater connected with any section,.but superheaters of any suitable type may be used, if desired.
The sand box can be located at any suitable point on the locomotive and mechanical stakers, or other mechanism, may be used which may be essential to the operation of 4the locomotive, but which are not shown in` order to avoid confusion.
lt will be seen that each section of the boiler. is comparatively short so that there will be less fluctuation in the height of water and less danger of exposing the crown sheet of the fire box when running down i grade than if the'boiler sections were connected by steam and water pipes. In fact, the variation of the water lever would be no greater than that. of an ordinary locomotive. There are n o articulated joints carrying either high or low pressure steam or injection water, as eaih section may be fed 4by separate injectors obtaining water from the tender by means of hose connections in `the ordinary way at the different points of valve 34, steam pipe 35, to the valve chamber ofthe high pressure cylinder 9, and from this cylinder through the pipe or receiver 36 to the valve chamber of the low pressure cylinder l0. The exhaust from this cylinder will pass through the pipe 37 to the exhaust pipe 28 at the rear of the tender to the atmosphere, or it may be used wholly, or in part, to heat the water 'in the tender. lin some instances, where a'second tender is used, it may be a driven tender and part of the steam from the high pressure cylinder may pass to the valve chamber of the low pressure cylinder 10 and part to the valve chamber of the low pressure cylinder on the frame of the' second tender. v This tender may be used where a greater capacity for coal and water is required. The rear tender, in this'instance, may carry the water and the sectionnext to the engine mayI carry the coal, if coal is used as the fuel.
By this construction, I obtain the maximum amount of tractive force generated by a single unit operated by a single crew with a minimum of dead weight. A further advantage of this construction is that the overhang of the boiler in passing around curves is very small, as each section of the boiler is comparatively short, and, consequently, the lateral displacement in passing around a 'curve is insignificant.
As remarked above. the water in the boiler of short sections will have less fluctuation in height. As one boiler section is entirely independent of the other with regards steam, there are no high pressure joints which are a constant annoyance in this type of locomotive.
The locomotive is operated by means of throttle and reverse levers located in the cab of the locomotive, as illustrated by dotted lines, Fig. 3. and connected to the throtthe rigging of the two engines, so that both valves will operate simultaneously. The same thing holds true with regards the power reverse gears. Each of these gears is arranged to operate the valve motion on the two articulated sections.
