A CORPORATION STEAM-GENERATOR.

SPECIFICATION forming part of Letters Patent No. 790,792, dated May 23, 1905.

Application filed September 9, 1904. Serial No. 223,868.

To LZ' wwm/ it may concern:

Be it known that I, JOHN S. KIDDEY, aciti- Zen of the United States, residing at Canton, in the countyof Stark and State of Ohio, have invented certain new and useful Improvements in Steam-Generators; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, and to the numerals of reference marked thereon, in which# Figure l is a vertical section of the furnaceL wall, showing the proper arrangementof the drums or boilers and their proper connection. Fig. 2 is a horizontal section on line 2 2, Fig. l. Fig. 8 isa detached view of thelowerlefthand drum or boiler, shown in Fig. l, except that the vertical series of water-pipes are not shown in reference to said drum or boiler.

Similar numerals of reference indicate corresponding parts in all the figures of the drawings.

In the accompanying drawings, l represents the furnace-wall proper, which is formed of brick or other suitable material and of a size to receive the various drums or boilers and to permit them to be arranged in substantial accordance with the arrangement illustrated in Fig. l, and as shown in Fig. l the drums or boilers 2, 3, 4, and 5 are arranged about equal distances apart and the drums or boilers 4 and 5 located substantially in a vertical line above the drums or boilers 2 and 3. The drum or boiler 6 is located in a plane above the tops of the drums or boilers 4 and 5, which boiler receives the steam generated in the drums or boilers below said upper boiler and. also the steam generated in the various pipes hereinafter described.

The front wall of the casing-wall is provided with the usual fire-door 7, and it will be understood that any desired number of doors may be employed, owing to the fact that the drums or boilers extend crosswise of the boiler casing or walls instead of lengthwise.

The bottom or lower portion of the combustion-chamber is provided with the ordinary grates 8 and the lower forward boiler or drum 2 located above the combustionchamber.

At the rear of the combustion-chamber proper is located the back wall 9, which back wall is inclined upward and rearward, so as to guide or shunt the flame, heat, and smoke upward between the boilers 2 and 3, {irst passing the water-tubes l0, said water-tubes being connected to the boilers 2 and 3 in such a manner that water connection is maintained between the boilers 2 and 3. After the heat and iiame have passed the water-tubes 10 their source will be upward under the pipes 11 and the baffle-wall 12, passing the water-pipes 13, which water-pipes connect the boiler 3 and the boiler 4. Vithin one ot' the pipes l0 and one of the pipes 13 is located an air-pipe, which air-pipe is extended through theboiler 3 and is for the purpose hereinafter described. The heated air, together with the flame and smoke, will ascend upward and in contact with the boiler 4 and the curved top 14 of the furnace-wall, and by reason ot' the draft of the chimney or tlue 15 the heated air and iiame and smoke will be shunted downward, passing the pipes 16, 17, and 18, the pipes 16 and 17 all communicating with the upper boiler 6 and the pipes 18 communicating with the boilers 4 and 5. As the heated air and flame are carried to the ilue or chimney they will pass the pipes 19, it being understood that the downward passage is upon the opposite side of the balie-wall 12 from the upward passage, or, in other words, the upward passage is under the battle-wall and the downward passage above said baiiiewall, which baffle-wall is held in place by the pipes l l or their eq uivalents. It will be understood that the wall is of light construction, as the only object is to cut olf the direct draft Jfrom the combustionchamber to the flue or to produce a divided upward and downward draft.

By locating the various boilers or drums 2, 3, 4, 5, and 6 as illustrated and connecting them by means of the various pipes they are all connected together and in such a manner that the steam generated in the various boilers and tubes will find its way to the upper boiler 6, which boiler is located where it will receive the heat arising from the combustioncharnber, and by providing the up and down draft all of the boilers and all of the tubes will present radiating-surfaces.

For the purpose of producing what might be termed a more rigid connection between the various boilers some ot' the connectingpipes arecurved, and for the purpose of producing a strong connection between the various boilers the water-pipes should be, and preferably are, staggered, as illustrated in Fig. 8.

The boilers or drums 2, 3, 4:, and 5 are held in fixed relative position with reference to the furnace-wall by setting the ends of the various boilers in the end walls of the furnacewall 1, so that each drum or boiler is provided with independent supports.

From the boiler 2 extends the inclined wall 20, which inclined wall forms the top of the combustion-chamber at its forward portion.

The fu rnace-wall is provided with the cleanout opening 2l, which clean-out opening is provided with the door or doors 22. The object and purpose of this arrangement is to provide a means for removing from time to time the soot or ashes that may accumulate upon the top of the inclined wall 20. The rear side of the furnace-wall is also provided with the opening 23, which opening leads into the pit 24, it being understood that the opening 23 is to be provided with adoor or doors.

The feed-pipe 25 may be connected to the boiler 5 or it may be connected to any of the different boilers;l but in 'any event it will be understood that a single feed-pipe is designed to supply water to all of the various drums or boilers and their connecting-pipes.

For the purpose of providing means for cleaning the interior of the furnace-walls end doors 27 may be provided and are so located that access may be had to the interior of the structure.

For the purpose of preventing the water from backing up the pipe 26 is provided, which pipe is located in one of the connecting-pipes l0 and 13, said air-pipe being extended above the level of the upper' horizontal pipe l0 or the curved pipe of the series, by which arrangement the accumulation of air will be carried above the level of the boilers 2 and Stduring the time the said boilers or drums are being filled; -but after the full supply of water has been fed to the generator proper the air-pipe in a sense becomes an idle element, and its use is especially to prevent the backing or' water during the time the generator is being refilled.

For the purpose of providing a means for cleaning the boilers or removing the water therefrom the ordinary blow-out pipes 28 are provided and are located in the usual manner.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent. is-

1. In a steam-generator, a series of drums located laterally adjacent, said series consisting of two pairs of drums, one pair located above the other, and the remaining drum of the series located above the Lipper pair of drums, pipes communicating with all the drums of the series, a bafHe-wall extended upward from one of the lower pairs of drums to one of the upper pairs, said baiile-wall extended in an inclined direction between the upper and lower pairs ofdrums, a combustion-charnber located below the baiiie-wall and a chamber located above the baffle-wall and one of the series of drums located entirely below the baffle-wall and two of the series of drums entirely above the baflie-wall, and the remaining drums of the series located coplaner with the baiie-wall, and a Hue leading from the chamber located above the baffle-wall, substantially as and for the purpose specified.

2. In a steam-generator ot' the class described, the combination of-a series of drums located laterally adjacent, and in dierent horizontal planes, four of the series being located in two different horizontal planes and one of the series in a horizontal plane above the remaining drum of the series, pipes communieating with all of the series of drums, abaiilewall located in an inclined plane dividing two of the series of drums-coplaner, and one of the remaining series located below the balewall and the two remaining drums of the series located entirely above the baiiie-wall, a combustion-chamber located below the bafflewall, a flue-chamber located above the baffle-- wall, an inclined wall dividing the combustion-chamber and flue-chamber, and a rear pit located at the rear of the furnace, substantially as and for the purpose specied.

3. In asteam-generator, the combination of a series of drums, pipes communicating with all the drums of the series, a combustionchamber and a due-chamber, a battle-wall located between the combustion-chamber and the luechamber, and an airpipe located within pipes, said air-pipe extended through one of the drums of the series, substantially as and for the purpose speciiied.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.
