rarest eerie STEAM' POV/ER PLANT.k

Be it known that 1, Hiinvnr W. BELL, a citizen of the United States of America, and

,a resident of Boundbrook, county of Somerset, and State of New Jersey, have invented certain new and useful improvements in` Steam Power Plants, of which the following is a speciiication, reference being had to the accompanying drawings, forming a partthereof.

.My invention relates to new and useful improvements in steam power plants and its object is to provide a'steam generator of extremely light and very simple construction which is capable of working at high efficiency. Another object is to provide a structure of such lightweight that it is suitable for use with airplanes.

Another object is to combine a generator of my novel constructionwith a motor and a pump in such a way as to cause th-e water supply to the boiler to vary automatically with the speed of the motor.

These and other objects of my invention will be set forth hereinafter, and in order that my invention may be thoroughly understood I will now proceed to describe the same in the following specification, and will then point out the novel features thereof in appended claims.

Referring to the drawings:

Figure 1 is a longitudinal section of a boiler made accordingl to and embodying my invention. togetherv with a steam turbine, a condenser, a pump and other parts shown diagrammatically in elevation..`

Figure 2 is a transverse section of the boiler. on a larger scale.

Figure is a longitudinal section of a partlof one of my improved boilers, also drawn on a larger scale than that used in Figure 1. in order to more clearly show its construction.

Like characters responding parts designates a greater length than diameter. It is .preferably tapered somewhat so that its form is that of along and comparatively narrow truncated cone. 11 is a water inlet pipe connected` with one end of this pipe coil, and 12 is the steam outlet pipe connected with the other end of the pipe coil. .Y The coil is covered with a heat insulator 13 such as of reference designate cor in all the ligures.

yAt the steam outlet mouth piece 2O is provided which may be made flaring asshown. 'In the center of this mouth-piece is an oil burner 21 to liquid fuel is supplied from a reservoir 22 through a pipe '23 in which is a lvalve-24. The reservoir'22 if below the burner is closed and arrranged to be supplied with pressure introduced at 25 The apparatus shown in Figurevl is designed for use in an airplane. In this figure, designates a steam turbine with which'the steam pipe 12 is connected. 31 is the exhaust pipe from the turbine to a condenserA 32 the outside of which is a metallic :a'rnun c. FRASER,

end of the structure a whichl vanes of which are curved and inclined as shown, and at the base of which is a water chamber 33. The water chamber is connected by av pipe 34 with the intake of a pump 35 which is driven by the turbine 30 and the outlet of which is connected with the water inlet pipe 11.

The turbine is preferably supplied with` reduction gearing within the casing 36 by means of which its rotor is connected with a propeller'shaft 37. The propeller 38 is preferably vplaced in front of the condenser 32 and the intake mouthpiece 20.

I will now 'describe the operation of this a-pparatus.` A 'flame from the burner 21 is introduced at one end of the pipe coil 10 and the hot gases therefrom are passed' through the tube formed by this coil. f The heat is absorbed bythe waterV in the pipe coil' which is thereby turned into steam. The hottest end of the pipe coil is at the steam outlet end not only because the heaty is introduced at this end but because of the circulation of water and steam inthe coil. The result is that practically all of the heat is absorbed and that the gases discharged from the water inlet end of the coil are comparatively cool. Another result is that the water in the pipe coil enters at the condenser temperature and its temperature is gradually raised as it lmoves toward the steam outlet end. Before it reaches the outlet it is vchanged into steam and thissteam Aas it advances 'becomes superheated. The

tapered ormv of the pipe coil is preferred as it helps to make' the absorptionof the heat more complete.

The rotation of the turbine drives the I pump 35 which isiarranged tosupply water to the pipecoil `as fast as it is needed.` lt'is obvious that the circulationof water is proportional totthe `speed `of the turbine; The

speed of the turbine `is proportional to the intensity of the ilaineand it followsthat the speed of the turbinefniay be regulated by ad gusting the valvefQep No other valve is needed,` nor is itonenessarytoA haveanywater gauge,injector or safety gvalve, `1 The pipe l coil l() is made `of material of sufficient stri-ingth` to withstand high pressures and whieh will not burn out when filled with dry steam and subjected tothe heat of the flame. `When the apparatus is used on an airplane the pipe coil tubeis placed ina fore Vand aftpositiomso that the movement "of ther apparatus through the airfwillfaid in carrying"` `the gaseszpthrough the longtube formedbyl the pipe coil. y The flaring shape of the mouth-piece 20 assiststhis functionas does also the relative position ofthe propeller Sdwhileli acts as a fait yThe gases thus introduced atene-end of, the tube formed by thepipe Coil,` passgfreely tlierethroughbut are `retarded somewhat by, the taper of the i y, tube The/propeller alsof helps to lieep the condenser l 32 cool.;

The apparatusis desirable for `war airplanes as itlhas no delicate `parts `and is not easily 'vulnerable.,` lt` is immune frein ein plosion and the fire rislr is` reduced toa niinil mum becausethe fueloil used need not ybe of nor is it necessarily limited to thouse of` gene` erating steam., `lt is well within `the scope of: this invention to` use the znovel structure as a heater` fori water fo'ri'exaniple, and l intend `no limitations other thanthose imposed bythe appended elaiins.` l l Nhat I elaini is:
