' Specification of Letters Patent.

Application filed .Tune 19, 1911. Serial No. 634,131.

To all lwhom, t may concern.'

Be it known that I, ALBERT L. AUSTIN, a citizen of the United States, residing at Lakewood, in the county of Cuyahoga andy State of Ohio, have invented a certain new and useful Improvement in Steam-Generators, of which the following is a full, clear, and exact description.

This invention relates to improvements in the type of steam generators which forms the subject matter of my allowed application Serial No. 601,557, led January 9, 1911.

prior application, particularly in respect to economy of fuel consumption, and time rey quired to get up Steam. e

The accompanying drawing shows and the i following description gives in detail the particular exemplificationv of the invention which I now regard as best; and the'features of novelty are clearly defined in the appended claims.

In the drawing, Figure 1 is a central vertical section of a steam generator embodying the invention. Fig. 2 is a sectional plan view on the line 2,-2 of Fig. 1. Fig.l 3 is a sectional plan view in the plane of line 3e-3 on Fig. 1 with the tubesremoved.

The generator as shown includes a casing 1 made of sheet iron or other suitable material. Across it, at a suitable elevation, a partition 3 is secured, thereby forming above this partition and within the casing the water chamber 2. Another partition 4 is secured across thecasing 1 near the lower end thereof, thereby forming between it and the partition 3 a coil chamber 5, and below said partition 4 a burner chamber 6. A tube 7 is tightly fitted in or over a central opening in the partition. 3, and extends upward therefrom through the water chamber and projects into the steam dome 8 which is on top of the water chamber and in communication therewith. The upper end of the tube 7 is closed by a cap 9. yA second tube 10 which is preferably made of asbestos or some other heat resisting and non-conducting material is supported by the partition 4ever a cen-V tral opening therein, and this tube 10 extends from the partition 4 upward into and nearly to the top of tube 7. The tube 10 is of considerably smaller diameter than the tube 7, and therefore an annular down flue is formed between them.

Vithin the coil 'chamber 5 are a plurality of coils 12 of pipe,each coil being disposed on inclines as shown, and the upper convolution of each coil being connected with t-he water chamber 2 through the partition 3.

The pipes which are continuations of the lower convolution of each coil are extended laterally under, or through a hole in, the lower end of the tube 10, and these several pipes 13 extend upward through tube 10, and are connected with the cap 9, through 'which they communicate with the steam drome. y

A burner 14 is disposed within the chamber 6 directly beneath the lower end of the tube 10, so' that the re blast from said burner will be discharged directly into the lower end of this tube. The products of combustion rising in this tube are in intimate contact with the pipes 13 therein, and quickly heat them, and the small quantity of water they contain, transforming the latter into steam in a short time. This steam is discharged from the upper ends of said pipe into the steam dome, from which it may be carried to the point of use through a pipe 15.

The products of combustion emerging from the topy of tube 10 are deflected and flow down in theannular liue between the tubes 7 and 10, and are discharged into the coil chamber for the purpose of heating the coils therein, andthe water which they contain. A conical baiie plate 16 lixedto the casing 1 extends therefrom inward and downward. The heat and products of combustion, in order to escape from the coil chamber, must pass down through and in intimate contact 'with the coils beneath this conical baflie plate; and then they flow 'into the chimney flue or pipe 17. The side walls of the coil chamber are made up of four doors 18 and four intermediate frame members 20, to which these doorsare hinged. The balilelplate 16 is made in four parts, one of which is fixed to each of these doors.

While the specific construction shown has been described, it is to be remembered that the invention as denedby the claims is not necessarily limited to the specific construcv tion, but that said claims are intended to indesigned with special reference to getting up steam quickly, and to continuously producing low pressure steam with a minimum of fuel consumption. It is quite obvious that these results will be attained, because the pipes 13 within tube 10 will be in intimate contact with all of the heat .produced by the burner, and that this contact will be maintained during all of the time said heat is flowing upward in the tube l0. This heat is easily sufficient to transform into steam the small quantity of water which these pipes contain. Moreover, as before stated, the entire heat from the burner 14 is first utilized for this purpose, and the residuum of heat of the products of combustion flowing down the flue between the tubes 7 and 10 are carried in intimate contact with the coils and initially heat the water therein so that when the apparatus is operating continuously, the water flowing from the coils into the pipes 13 will be well heated while still in the coils.

Having described my invention, I claim:

l. In a steam generator, the combination of a water chamber7 a tube passing through the same having a closed upper end and an open lower end, an inner tube open at both ends and Yextending from a point within the outer tube near the upper closed end thereof downward to a point considerably below the lower end of said outer tube, pipes connected with the water chamber and carried into and up through the inner tube, said pipes being connected at their upper ends with openings through the closed head of the outer tube, and a burner disposed beneath the lower open end of the inner tube.

2. In a steam generator, the combination of a water chamber, a coil chamber below the same, a tube closed at its upper end extending up through the water chamber and communicating at its lower end with the coil chamber, a second tube extending down within the first tube from a point near the upper end thereof to a point adjacent to the burner, a burner disposed below the lower end of the said tube, and pipe coils connected with the water chamber and disposed within the coil chamber, pipes which are a continuation of these coils which enter the inner tube near the lower end thereof and extend up through the same and discharge through openings in the closed upper end of the outer tube.

3. In a steam generator, the combination of a water chamber, a coil chamber below the same, a tube which extends up through the water chamber and is closed at its upper end and is in communication at its lower vend with the coil chamber, a second tube which is secured over a hole in the floor of the coil chamber and extends upward therefrom into the tube first named to a point near the upper clo-sed end thereof, a burner disposed below the lower end of the inner of said tubes, pipe coils located within the coil chamber and communicating with the water chamber through the bottom thereof, said coils being continued as pipes which enter the inner tube near the lower end thereof and extend up through it and are con` nected with openings through the closed upper end of the outer tube.

4;. In a steam generator, the combination of a water chamber, a coil chamber below the same, a tube extending through the water chamber which is closed at its upper end and open at its lower end, a burner chamber below the coil chamber, a tube open at its lower end which communicates with the burner chamber and extends upward through the coil chamber and into the tube first mentioned to a point near the closed upper end thereof, a plurality of coils of pipe located within the coil chamber, the coils whereof are inclined in a direction inward and downward from the outer wall of said chamber, the upper convolution of each coil being connected with the water chamber, and the lower convolution being extended into and upward through the closed top of the outer tube, a downwardly and inwardly inclined baffle plate fixed to the wall of the coil chamber, said coil chamber having below said baffle plate an opening for the discharge therefrom of the products of combustion.

In testimony whereof, I hereunto affix my signature 1n the presence of two witnesses.
