19 Claims. (Cl. 122434) This invention relates to water heaters and from the turbine passes, through pipe 9, intd more particularly to locomotive feed water heatmain exhaust conduit which leads from the ers; and is especially applicable to, and useful valve chest 11 to the flexible connection 12 bein connection with heating water in, the tenders tween engine and tender.

I have devised two that I have illustrated a locomotive having an Way 0f doing this- In there will be seen engine 2, and a, tender 3 in which I have emb di d a series of conduits or pipes 34, each one of which the present invention. The engine of the 1000- eXtends frem a point heal" the p of e c0mmotive is equipped with a centrifugal water pump partmeht a point adjacent the bottom of the e driven by a turbine 5, steam being delivered to proximate rearward compartment, the rearmostthe turbine, as from a turret (not shown), compartment 24 being in communication with through pipe 6, valve 7 and pipe 8. The exhaust atmosphere by virtue of the inlet 28. Alternatively, as seen in Fig. 3, I provide small conduits 34a individually venting the several compartments to the atmosphere. While the latter device is slightly simpler, I prefer the former, as there is combined with it an added useful function, to wit: steam or heated air passing up through the water in any given chamber is taken off by pipe 34 at a point above the water level and, under its own pressure, discharges into the adjacent rearward chamber beneath the water level, thereby fully utilizing heat therein and also avoiding any possibility of discharging excess steam into the atmosphere which is obviously objectionable in railroad operation.
The heating unit, proper, is extremely simple, comprising, at it does, merely an extension 140. of pipe 14, lying substantially along the floor of the tender tank and extending through all but the rearmost of the partitions or walls 23. This pipe or conduit 14a has a closure cap 14b at its rear end, and has, in the several compartments, perforations or holes 14c, 14d and 14e, respectively. It should here be observed that the crosssectional area of the steam outlets is made progressively smaller in each chamber serially rearward, either by making the apertures or holes smaller, or, as here shown, by making them fewer in number. The effect of this arrangement, coupled with the fact that there is naturally greater resistance to the steam flow in proportion to the greater length of travel through the pipe, is to cause the greatest discharge of steam into chamber 27 and, step-by-step, less discharge into each of chambers 26 and 25, no steam being delivered into chamber 24 (with the exception,
possibly, of a small quantity through the last vent-pipe 34) so that the latter chamber has a relatively cold body of water therein suitable for use in the usual injector (not shown) in case of pump failure.
From the foregoing it will be evident that by my invention the weight, complication, first cost, and expense of inspection, repair and maintenance of feed water heating equipment is very materially reduced as compared with prior known devices; that a heating and segregation of the water by stages, or progressively, is attained in a very simple and effective manner; that the exhaust steam is utilized to the fullest extent, and especially so in the form of construction shown in Figs. 1 and 2, in which each chamber is vented to the next cooler chamber; that the tender itself is utilized as the heater in an extremely simple manner and with the addition of a minimum of additional apparatus; that the invention may be almost as readily applied to existing as to new equipment; and that, in general, the objects stated at the head of this specification are realized by a simple, inexpensive and rugged construction.
