Specification of Letters Patent.

I Patented Nov. '7, 1911.

Application filed April 23, 1906, Serial No. 313,224. Renewed April '20. 1911. Serial No. 622,325.

To all whom it may concern:

Be it known that I, RICHARD L. TEMPLIN, a citizen of the United States, resident of Cleveland, county of Cuyahoga, and State of Ohio, have invented a new and useful Improvement in Water-Heaters, of which the following is a specification,the principle of the invention being herein explained and the best mode in which I.have contemplated applying that principle, so as to distinguish it from other inventions.

My invention relates to improvements in devices for heating water and particularly to devices of this character that are of sect-ional construction.

The object of the invention is to produce a water heater that will present the desirable qualities of simplicity of construction and efficiency of operation, and that will provide a. maximum heating space for a minimum am unt of water.

Saidinvcntion consists of means hereinafter fully described and particularly set forth in the claims. i Y

. The annexed drawings and the following description set forth in detail certain'means embodying the invention, such disclosed means constituting but one of various forms in which the principle of the invention may be used.

In said annexed drawings: Figure 1 representsa front elevation of one of the sections that go to make up a vertical water heater embodying my improvements; Fig. 2 is a vertical, longitudinal cross-section of such a heater represented for the sake of simplicity as being made up of only four sections; Fig. 3 represents a. horizontal transverse cross-section of such heater'taken on line 3-3, Figs. land 2; Figs. 4 and 5 represent similar horizontal transverse crosssections of-single sections of the heater respectively taken on planes indicated by the lines 4-4 and 5-5, Fig. 1; Fig. 6 is a side elevation of a section showing the manner in which my invention may be adapted to a horizontal heater; while Figs. 7 and 8 are respectively a vertical and a horizontal crosssection of yet another form of my heater.

The primary use for which a heater of the type illustrated is intended is in the heating of rooms orapartments by means of radiators connected in the usual manner. It may, however, bereadily adapted for use in heating Water for domestic purposes as for the water to and from the heater.

the laundry, bath, and kitchen. It is furthermore designed for use with a fuel that produces little or no soot or ash that is likely to be carried along with the gaseous products of combustion-and deposited in its passages or flues; in other words, it is intended primarily for use with gas, but coke and anthracite coal, with little or no modification in its structure, may be equally success'fully employed. It is well known that with gas in particular much difliculty is ex perienced in obtaining heating results comrfnerlisurate with the calorific value of the I shall now proceed to describe the structure of my improved heater and later point out wherein it-is enabled to utilize to the. fullest extent this fuel energy for the specific purpose in hand, that of heating water.

In Fig. 1 is shown in elevation one'of the intermediate water-holding sections that enter into the heater structure. Such section is designed to be cast integrally of iron or like metal. In outline it follows the design commonly found in sectional heaters, and consists of a hollow bodyportion A with legs A extending downwardly therefrom on each side and inclosing the fire-box 0. Each section is further forined with an aperture or flue A for the smoke near its upper end. Successive sectionsare joined together so as to have free internal connection through apertures a, of which there are three, one in each leg and a 'third at the top of the sections. Such junction is efiected by means of either slip-nipple joints orrubber washers fitted between the abutting lips of the apertures, as may be desired, and is immaterial so far as concerns my present invention. Conduits B, B, connected with the apertures a of the end sections of the heater, Fig. 2, respectively serve to conduct Water sections A are flat, and are formed with a perfectly smooth interior, save for a short distance directly over the fire-box C which is corrugated. The corrugations a are vertically disposed and extend preferably for of the section. Each section is provided I around its outer edge with laterally projecting flanges a that serve when the sections are assembled together to keep adjacent sections a fixed distance apart. It is evident that such flanges serve at the same time to completely inclose the open spaces thus formed between the sections except directly .tions as appears in Figs. 1 and'3, in order that they may better resist the more intense heat of the fire-box as well as more fully utilize the same. The open spaces between adjoining sections, it is obvious, serve to conduct the heated gases, that arise from the combustion taking place in the fire-box upwardly along the walls of said sections and thence out flue A The flow of such gases is not direct, however, but is diverted by means of transverse flanges or splines a disposed on the faces of the sections and alternately of the form shown in 'Flgs. 4 and 5i; thes e flanges or splines, being s1m1- larly arranged on opposing faces, form flues through which the aforesald gases are obliged to pass, Figs. 1 and 2 Intermediately of flanges a are projections designed primarily as heat-absorbing means. These projections may take the form either of pins arranged in rows, or preferably of other flanges a somewhat lighter than flangesa and arranged in the zig-zag manner clearly shown in Fig. 1. Theseflanges may be either of the same width as flanges a or else narrower. In Fig. 2 they are shown in the space to the ri ht as being of equal width with flue-forming flanges u while in the remainingspacesof such figure they are shown as being of less width. In the latter form the serve solely as heatabsorbing flanges w ereas in the first form they in addition serve to subdivide the fiues formed by flanges a into a number of smaller fiues. By the zig-zag arrangement of these intermediate flanges the current of gases passing'aldng the main flues is equally apportioned among such smaller 'flues.

Flanges a lying intermediate of the firsttwo major flanges a as also the latter themselves are made hollow after the same fashion as lateral flange a, and for the samereason.

I prefer to employ the intermediate flue construction when the device is designed to be used with gas, either natural or artificial, as a fuel; on the other hand the intermediate flanges should not extend entirely across the passage but should serve as heat-absorbing flanges simply, when anthracite coal and coke are being used since they usually bring these flue openings into sta front and rear sections it will be seen, however, differ in no wise from the standard intermediate sections, except that, as might be expected, all the flanges are omitted from their outer faces,.and the hollow body-portion A extends entirely to the bottom, there being no legs. In the front section, moreover, the smoke-flue A is closed and an opening provided for the doorway, the door whereby it is closed being hinged on studs cast integral with such section and projecting from its face. From an inspection of Fig. 6 it will likewise be clear without detailed description that my improved form of construction is readily adaptable to,a horizontal heater, the arrangement of flanges a being modified accordingly. In this horizontal form, moreover, I do not many intermediate flanges a are used are of employ so and those that the same dimensions as flanges a. But little more modification is required to adapt my heater for use with a base-burnerinstead of with the style of firebox illustrated in both Figs. 1 and 6; while in Figs. 7 and 8 I show how my systemmay be embodied in a vertical heater in which the sections are horizontally disposed instead of up and down as in the first-described form.

The sections are preferably circular as' shown, being in fact hollow disks D with central bosses provided with openings (1! whereby successive sections are joined together so asto have free internal connection and at the same time leave an open space between opposing outer faces, such space being inclosed by the peripheral flanges d of the sections. Such joining of the sections may be effected by means of screw-threaded nipples since the several sections having but the single connection may be rotated with respect to each other. The arrangement of grate or burner C is the same -as before and provision is made for the escape of the products of combustion upwardl by providing each section with a plurality, of segmental smoke or flue openings d three being shown in the heater illustrated. Successive sections, Fig. 8, are arranged so as to gered relation with each other. According y in passing from the flue openings of one section to those of the section next above the heated gases are obliged to pass through the s ace intermediate of said two sections whic subdivided into a greater or less number of small passa es, as maybe desired, by concentrically isposed flanges d on the opposing faces of the sections. The character of these flanges is exactly the same as those described in connection with the first form and they, of course, serve the same function. In

order to insure a thorough circulation of the water within the indivi ual sections each is subdivlded into compartments -as indicated, by means of diaphragms d transversely disposed intermediately of the two central openings (Z of such section and by partitions d? extending radially into the segmental chambers formed between the flue openings (1 The ascending-current of water is thus compelled to circulate entirely through one section before it can reach the one above. If desired, in order to prevent undue radiation of heat from the boiler in either form, the

,whole may be incased in an asbestos-lined jacket in the same way in which furnaces and steam pipes are thus protected. Furthermore, where the nature of the fuel is such as to suggest the necessity of periodically cleaning the flues of the heater, the lateral or peripheral flanges may be omitted from one side of the sections and a removable cover or door provided whereby access may be had to the open spaces between the sections and soot or dust'easily removed.-

From the foregoing description it is seen that by my construction the water to be beated is held in thin sheets in the flat vertically disposed sections. Around the latter play the heated gases ascending from the fire-box, such gases being forced to wind in and out among the main flues formed by flanges a and delivering up the major portion of their heat to the intermediate heat-absorbing flanges lying within such main flues before they finally escape by Way of the smoke flue. The walls of the section are in this manner prepared to absorb the greatest possible amount of heat from such gases and this they, of course, radiate in turn to the water within them. Such water, in the preferred form of heater, flows unimpeded upwardly as fast as it is heated, there being no projections on the inner walls of the sections, or other obstructions in its course. In other words, instead of passing the water back and forth through devious ways across the heated space, I expose it in thin, freely-flowing sheets to the heat-absorbing walls of the sections. The means employed, although quite simple, thus expose a minimum amount of water to a maximum heating surface, and a relatively high degree of efliciency is accordin 1y developed.

1. In a sectional water-heater, a plurality of flat, hollow sections adapted to holdwater and provided with discontinuous lateral flanges or splines, said flanges or splines being disposed horizontally and adapted to substantially contact and thereby form flues when said sections are put together, .the openings of successive flues being out of alinement.
