Application filed February 26*, 1918. Serial- No. 219307.

To all whom it may concern .7

Be it known that I, AI C. GORDON, citizen of the United States, residing at Glens Falls. in the county of Warren and State of New York have invented certain new and useful :hroken away,x showing one of the sections tdietac'hed.

I r In order that the construction,mounting Improvements in Auxiliary Steam Generators, of. which the following is a specification.

This invention relates to an improved auxiliary steam generator for ship power systems and has asritsprimary object to pro vide a device of this character adapted to utilize the waste heat from. the ships boilers for generating steam which may be used along with the steamfroin the boilers for propelling the ship or for any other purpose desired- I The invention has as a further object .to provide device of the above described character adapted to be interposed in one oi the smoke-fines. of the ships boilers and providedwith awater jacket so that the heat passing through the hue and through the device will be utilized for heating the water within the said jacket to generate stcam therefrom.

The invention has as a still further object to provide a device of the above described character: which. will be formed in sections or units so that'- the size of thedevice may be varied to suit the conditions of different ships by simply increasingor decreasing the number of sectlon's or unitsemployed.

And the invention has as a stillfurther object to provide an improved arrangement embodiment of the invention and wherein .slmilar reference characters deslgnatecorresponding parts throughout the several views Figure 1 1s a fragmentary elevation showingmy improved devicein. connection with j erator, like the terminal sections, each ina; conventional type-of shipis boiler; three of the decks of the ship being also conventionally shown in section.

Fig. 2 1s a detail vertical sectlonal vlew showing the device attached and illustrating the manner in which the sections or units of the device are connected.

Fig.3 1s atransverse sectional vlew taken said: wall. preferably at quadrantl y Spaced points through one of the sections of: the device and showing the passages formed thereon .for establishing communication between the 8861510118, and

Fig.4: is adetail perspective view, partly and operation of my improved generator rnay be accurately understood, I have, in :the drawings; shown thedevice in connection with a conventional. type of ships boiler 10 having a smoke flue l1 and steam dome 12 Thedirst, second. and third decks of the ship are also conventionally shown at 13. Coming now more particalarly to the subject of the present invention, my improved device is formed with a body made up of a plurality of cylindrical sections or units: and Including terminal. sect ons'li and 15 re .sp'ectively, between which are arranged a plurahty of Intermechate sections 16 The

terminal sections

14 and 15 each include a rality of parallel circulating. pipes 21 opening into the water jacket and provided at the lower sides thereof-with flat upwardly diverging. deflecting faces for directing heated currents through the casing toward the wall thereof for more eflectuallyheating Formed on the water. jacket thereon is. a plurality of. radially extending tubular passages QQ-Which are vertically disposed. Preierably, these passages are of a radius corresponding to the width of the waterjacket. Opening into one of the passages of the section 14 is an inlet23- and H communicating With one of the passages of the section 15 is an outlet 24.

The intermediatesections 16 of the gencludea cylindrical casing 25 surrounded by an annular water jacket 26 closed at its ends Formed on the Water jacket at quadrantly spaced points are a plurality of vertical tubular passages 29 corresponding to the passages 22- of the terminal sections. It will thus be clear that the terminal and intermediate sections are. as shown in Fig. 2 of the drawings, adapte to mate end to end for forming the generator when the

passages

22 and 29 of the sections will aline vertically of the generatorbody to provide passageways extending from end to end thereof. However, in this connection it hould be noted that the said sections are so arranged one upon the other that the circulating pipes of one section are disposed at right angles to the pipes of the preceding section. Formed at the inner ends of the passages 22 of the

terminal sections

14 and 15 are oppositely directed lateral ear or lugs 30 and fitted through these lugs to extend at opposite sides of each of the passageways are'tie rods 31 detachably connectingthe said sections. The sections are thus rigidly held together to provide a continuous smoke passage through the body and, as shown in Fig. 1, the body is inter.- posed in the smoke flue 11 of the boiler 10 to extend vertically above the boiler with the reduced extension 19 of the section 14 of the generator body receiving one end of the flue while the opposite end of the flue is fitted over the reduced extension 19 of the section 15. Thus, the waste products of combustion from the boiler will flow through the generator. In Fig. 1-, I have shown the generator of a length to extend upwardly through the first and second decks of the ship. However, as will be clear in view of the preceding description, the length of the generator may be readily varied to suit the conditions of different ships or the requirements of different boilers by simply increasing or decreasing the number of sectlons employed in the body of the generator.

: As will now be observed upon reference to 'Fig. 2, the

end walls

20 and 27 of the sections are, at the passages 22 and29, formed with reglstering openings and detachably engaged within these openings are double ended coupling nipples 32 wedged at their ends within the said openings and establishing communication between the passages,

'mak-ing f the passageways continuous, vertically of the generator body. This construction provides a very convenient arrangement whereby the passages of the sections may be readily connected and since the nipples are arranged to establish communication directly between the ends of the passages, the said passages will, by being enlarged radially with respect to the water jackets, provide free circulation between the water jackets of the sections. Connected with the inlet 23 of the section 14 is a pipe 33 communicating with which is a water supply pipe 34: having a usual cut off valve 35 interposed therein. The pipe 33 is earried to a water tank 36 mounted on a level adjacent the upper extremity of the generator. Accordingly, this tank is, as shown in Fig. 1, arranged upon the second deck of the ship and is preferably equipped with a sight tube 37 Controlling communication between the tank and the pipe 33 is a usual shut off valve 38 in the said pipe. Leading from the outlet 24: of the section 15 is a steam line pipe 39 which is connected with the steam dome 12 and leading from the said dome in communication with the pipe 39 is a steam supply pipe 4:0 in which is preferably interposed a usual out off valve 11." Leading from the pipe 39' to the tank 36 is a branch pipe 42 and preferably a usual cut off valve 43 is interposed in the pipe 39 between the generator and this branch pipe.

In use, water is admitted through the pipe 34 to flow into the generator and into the tank 36, the level of the water in the generator being easily determined by means of the sight tube 37 upon the tank. In order to allow for the rolling of the ship, the tank is preferably only partially filled with a corresponding-partlal filling of the generator, so that space may be allowed in'the uppermost sections of the generator for rise and fall of the water therein with the movement of the ship. As will, of course, be understood, the water will, when the generator 15 thus filled,'flow into the circulating

pipes

21 and 28 so that the waste products of combustion of the boiler 10 is passing through the generatoras previously described, will flow over these pipes and against the walls of the flue passage of the generator for heating the water therein. The steam thus generated will then be carried off through the ently of such boiler supply for driving other.

machinery upon the ship.

Having thus described the invention, what is claimed as new is:

1. An auxiliary steam generator including a body having a casing providing a continuous centralsmoke passage openingthrough the ends of the body, a water jacket surrounding the casing and uniformly spaced therefrom, the body being formed of inde-' pendent detachably connected sections and the space between the jacket wall and the wall of the casing upon each of the sections lll being uninterrupted, a water passageway formed on the walls of the jackets and open to the jackets, said passageway being enlarged to project outwardly from the jacket walls and establishing communication between the jackets of the sections, and an inlet and outlet for said jackets.

2. In a device of the character described, the combination with a boiler including a flue, of an auxiliary steam generator interposed between lengths of the fiue to form a continuation thereof and having a Water acket, a water supply tank, circulating pipes leading from the jacket at opposite ends of the generator and connected with opposite ends of the tank, a pipe forming an extension of one of said first mentioned pipes and having direct connection with the boiler for carrying off steam from the jacket, and valves interposed in said circulating pipes whereby said valves may be closed to cut off communication between the tank and jacket and the generator displaced from the flue.

In testimony whereof, I affix my signature.
