VAppiimttion mea August 30,1931).Y 'sgml No. 478;975;

' This invention relates to feed-water heaters for locomotives, and particularly` to "one which is interposed in the path of the eX- haust-ing gases of a locomotive `iireebox so `as. e' to utilize this heat, which would otherwlse with a .shouider 19., which fabuts fthe 'interior be wasted. k

The object of the invention is to provide a heater, of the character described, which may be inserted laterally through the side of a lol-i comotive, and which is provided with means for allowing the water therein to circulate with the water in the boiler of the locomotive to which it is applied. Another object is tok provide a heater which will accomplish the 'l just mentioned object, and which is of eX- trem'ely simple construction. Otherobjects may later become apparent. j

In the accompanying drawings: A Y

Figure 1 is a side View of a locomotive, a

53* practical embodiment of the present invention being applied thereto.

Figure 2 is an enlarged partially cross sectioned side view of theinvention removed from the locomotive.

Figure 4 is a longitudinal cross section' of the front end portion of the locomotive, showing the heater positioned therein.

LJ' Figure 5 is a lateral cross sectionof the front end of the locomotive, showing th heater as it appears from this end. A

In the drawings, in which similar numerals refer to similar parts throughout the sevv eral views, there is shown a locomotive 10v 15 of the locomotive, so that theV exhaust gases and smoke must pass under it before r they are discharged through the smoke stack 116 zofsthe locomotive.` TheloGGmQtivef'F-is shownf aequ-izpped' withl the" conventionalfspnmk arresting screen'l', and steam` exhaust; pipe y 18 whichulcreates a draft i-nthegsmoke 'boXl- The-.opposite side `of theft'anki =13fzis formed 65 wall ofthelocomotive shell, while ion theek-'z teriiorwalli va gasket 12.0 s pressed fby a retain-v ingaendzpl-ate2l :both gasket and 4end vplatebee` Y, ing provided to Vfbe 'inserted oven'rthe.-.s`h ml.i 60 l derediendfof thetank.

When.. the injector 11 is not being operated, the tank 13 will 4`be in open` circulation withrthe boiler, as the valve `28 will opento admit of thermosiphonic circulation. A hand valve 29 may be 9" supplied to the pipe 12 so that the water feed-V ing therethrough may be positively outV oi. Thisinvention provides a feed-water heater of simplified design, which may be readily removed from a locomotive for repairs,mand fwn which, when not actually injecting water into the boiler of a locomotive, is in open lcirculation therewith to prevent the formation of steam within the system. n

It is to be understood that this invention is not to be limited to the particular form here shown Vand described, but that the appended .claims 'are` to be broadly construed.

i I claim:

1.'A feed-water heater for locomotives Y Y provided with boilers'and water injectors,

comprising an elongate tank: having aperfA tures formed at its top and lbottom portions and with a flangel at one end and a reduced opposite end forming a shoulder, said tank being, adaptedy to beparranged laterally through the shell of vthefboiler Sorthat Vsaid `flange'x'abuts theexterior thereof, a collar Vfor insertionover the reduced end of said 5 tank and .against the exterior offthe shell of the locomotive, when said lshoulder rests against the interior-of the shell,a pipe provided to connect a top "aperture of Said tank top-the boiler at apoint-beneath .the water l line thereof,xa pipe provided to connect the water injector to a'bottom aperture of said tank, said last named pipe being provided with a branch vpipe which is adapte'dto connect with the bottom fof the boiler, *andV check -valves interposednin said last named `pipe and itsfbranch pipe.V

,Y 2: In a feed-waterA heater'vfor `a boiler, an

elongated tank provided with a vflange integral therewith and adjacent one extremity Y thereof, the iiangebeing formedto receive means lfor securingV thev flange .to -support the heater in an operative position', said tank belng so reduced nearits other extremity, as to form a shoulder on the elongated surface of said tank near the last mentioned extremity.

Y 3. In a` feed-water heater for a boiler, an

elongated tank provided with a flange inte-` gral therewith and'adjacent one extremity thereof, the flange beingformed to receive means 4for, securing thel flange to support the heater i-n an operative position, lsaid tank being so shaped near its other extremity as to form a 'shoulder on the elongate surface of .said tank near the last mentioned .eXtrem ity; Y
