This invention relates to improvements in water heaters, and more particularly to an improved construction in the water heater sections of thewater heater. Y The primary object of the invention is to provide hollowwater heater sections in which there is :maintained a positive circulation of water to thereby render the water heater more effective in operation.

Another object of the invention is to maint'ainthe surface of the water within the water heater sections relatively quiet, to thereby afford a more effective liberation ofthe steam therefrom.V y

Another object of the invention is to provide a waterV heatersection which is simple in constructiony eiiicient in operation, and inexpensiveto manufacture.

A stillfurther object of the invention is to provide a water heater section provided with improved means for more advantageously and effectively causing the heated gases to be distributed over the surfaces of the water heater section.

With the objects above indicated and other objects hereinafter explained in view, my

invention consists in the const'ructionand combination of elements hereinafter scribed and claimed.

Referring to the drawings,I

In the drawings there is illustrated a wan ter heater 'of usual construction, comprising a base 10 usuallyV of cast iron, the upper por- 45 tion of which is adapted to receive and sup- 192s. serial No. 265,321.

port a plurality of water heater sections 11. While four water heater sections are here disclosed as constituting the water heater, it should be understood .that any desired number ofsections may be employed depending upon the requirements of the i water heater. y

The base 10 contains and supports a plurality of burners 12 which are positioned adjacent the lower surfaces of the sections 11, and. said' burners are supplied "with fuel from any suitable source through the pipes 13. Y

Each4 Water heaterV section 11 is provided with an inlet lopening 14 for the? admission of cold water from any suitable source, being located at the lower corner vof the water heater section 11, while a steam outlet opening 15 is provided at the upper corner of the water heater section 11 diametrically opposite from the inlet opening 14. Each of these water .heater sections 11 isadapted to be positioned side by side upon the hase 10, and the inlet and outlet openings 14 and 15, re-

spectively, of each section are adapted to abut to provide a continuous passageway for the incoming water and for the outgoing steam. These sections are suitably clamped together by transversely positionedv bolts 16 disposed within grooves 17. at the upper and Vlower portions of the sections adjacent the inlet and outlet openings.

Theusual cover 18 is supported upon the upper portions of the water heater sections y11, and has a suitable opening 19 through which the smoke and gases can escape.

Upon the outer vertical sides of the water heater sections are a plurality of laterally extending lugs 2O disposed in horizontal rows, the lugs in each row being in staggered relation with respect to the lugs of each adj acent. row. These lugs are provided with divergingsurfaces upon their under sides and are adapted to deflect the hot gases to cause the latter to travel upwardly between the heater sections in a tortuous path. The diverging surfaces upon the undersides of the lugs extend preferably at an obtuse angle, as it has been found that by so forming the diverging surfaces of the lugs that the heated gases are more efficient-ly distributed over the entire surfaces of` the water heater sections 11 and caused to travel in a more circuitous path, thereby obtaining substantially a maximum in heating efficiency.

In the ordinary type of water heater section employed in connection with water heaters the section is ordinarily hollow, and the water which is admitted to the lower portion of thesection is heated by the flame of the gas burner.` The heated Water then rises to the top or upper portion of the heater section and the steam is liberated therefrom.

It will, therefore, be seen that there is nox positive circulation of the water within the water heater section. The failure of this water to circulate within the section is quite a disadvantage and affects materially the eficient operation of the water heater for the purpose for which it is employed.

To create a positive circulation of the water within the water heater section 11 there is provided a transversely extendingbaffle plate 21 formed integral with the sides of the water heater section. The baflie plate 21 extends substantially parallel with the bottom'surface of the water heater section 11, and 'preferably the bottom of the section and the baflie plate 21 extend at an incline from the back of the water heater section 11 toward the front. The bafHe plate 21 terminates short of the front and rear walls of the water heater section 11, so as to provide suitable passageways therebetween. space between the rear end of the baffle plate 21 and the rea-r end of the water heater section 11 is considerably smaller than the space between the underside of the baffie plate 21 and the bottom of the heater section 11 for a purpose to be later described.

At the upper portion of the water heater section l1 is a vsecond baflie plate 22 extending transversely of the water heater section and preferably formed integral with the sides thereof. This baie plate 22 extends at an invcline from the front of the 'water heater section towards the rear thereof and is considerably less in length than the baffle plate 21. The baffle plate 22 at the front end terminates short of the front wall of the level of the water within the water heater section lland functions additionally to maintainthe surface of thewater relatively quiet,

to thereby eect a more efficient liberation of the steam therefrom.

The-l T he circulation of the water within the water heater section 11 is effected in the following manner: As the cool water enters the water heater section through the inlet opening 14, it is heated by the flame of the gas burner 12, and tends to circulate in substantially a horizontal path toward the front of the water heater section, due to the fact that there is more space between the baffle plate 21 and the bottom of the section than there is between the rear edge of the baffle plate 21 and the rear wall of the water heater section. The upward inclination of the bottom of the water heater section and the baie plate encourages this tendency. As the heated water passes from under'the front end of the baiiie plate 21 it rises substantially vertically in a more or less well dened stream until it reaches the upper baiiie plate 22, when it is directed in substantially a horizontal path toward the rear of the water heater section due to the inclination of the baiiie plate 22;

The column of water at the rear of the water heater section 11 is somewhat cooler and,

therefore, slightly heavier than the column of water at the front of the water heater section. This gives the water a definite circulatory motion and thus renders the section much more efficient in its operation.

Vhile I have described the preferred embodiment of the invention, it is to be understood that I am not to be limited to the specific construction disclosed herein, as changes and modifications may be resorted to without departing from the spirit of the invention as defined in the appended claims.

Having thus described my invention what I claim is:

1. A section for boilers and the like comprising a hollow body member having an inlet opening and an outlet opening, a baffle extending transversely of said member and substantially parallel with the bottom thereof, there being passageways at opposite ends of said baffle, the cross section of the rear passageway being less than the cross section of the space between the baffle and the bottom of said member, and a second baiiie extending transversely of said member and positioned above the latter but adjacent the normal water level of said member.

2. A section for boilers and the like comprising a hollow body member having an inlet opening and an outlet opening, a forwardly inclined baffle extending transversely of said member and positioned adjacent the inlet opening, there being passageways at opposite ends of said baffle, and a second baffle inclined rearwardly and positioned adjacent the outlet opening and the water level and adapted to retard the upward flow of liquid within the body member.

3. A section for boilers and the like comprising a hollow body member having an inlet opening and an outlet opening, a bafiie inclined forwardly and positioned adjacent the bottom of said body member, a passageway at the rear portion of said bale of smaller area than the passageway beneath said bale, 5 a passageway at the forward portion of said baille, and a second baffle inclined rearwardly and positioned above the forward end of said first-mentioned baille but adjacent vthe water level.

In testimony whereof, I hereunto affix my signature.

WILLET E. STARK.
