WATER-HEATER.

Specification of Letters Patent.

Patented July 14, 1914 Application filed August 9, 1913. Serial No. 783,885.

To all whom it may concern Be it known that I, Gnonon T. Nnw- ELL, Jr., a citizen of the United States of America, residing at Passaic, Passaic county, in the State of New Jersey, have invented certain new and useful Improvements in \Vater-I-leaters, of which the following is a full, clear, and exact description.

This invention relates to portable waterheaters more particularly to the heatingcoils thereof, and has for its object, among others, to provide for use in such waterheaters an inexpensive heating-coil of special construction and arrangement whereby space is economized and a maximum amount of heating surface provided. and in which the coils or convolutions are so disposed that air currents or flues are practically obviated.

The particular features of improvement and some of the advantages flowing therefrom will be hereinafter described more in detail and finally set forth in the appended claim, reference being had to the accompanying drawing, forming part hereof, wherein Figure 1 is a side elevation, partly in section, of a water heater embodying my improvements, and Fig. 2 is a sectional plan view thereof, the section being taken on line 2-2 in Fig. 1. i

In the accompanying drawing, the numeral 1 indicates the casing of a water heater, within which is contained a heating coil preferably composed of a. single tubing of copper, looped orconvoluted, as shown, one terminal of the coil constituting the inlet 3 and the other terminal the outlet 4-. It will be seen that the coil is bent into a series of contiguous juxtaposed loops or convolutions, 5, arranged in substantially horizontally disposed superposed layers 3 to 17, respectively. The inletend of the coil, it will be noted, oasses from the upper portion of the casing in a horizontal plane toward the the left and then bends downwardly and through the end loops to provide a vertical portion 18, and near its bottom it again is bent as at 19 to run in a horizontal plane, and is then looped or convoluted at 20, and again looped as at 21, forming two additional loops; it is then looped again as at 22, to form two more additional loops, and then looped as at 23 to form two more loops, (the opposite side of this lowest layer of loops 21 22 and 23 appearing in the form of contiguous duplex-loops); it is then looped as at v 24 25, 26, 27 and 28, all the loops being arranged in substantially contiguous superposed relationship, and so on until a suiiicient number of layers of coils or loops is provided. It will be seen (Fig. 1) that the convolutions or loops of alternate layers are oppositely directed relatively to each other, that is to say (for instance) the loops formed by the coils, 21, 22 and 23 are directed oppositely to the direction of the loops 2%, 25, 26, 27 and 28. ing and at each side thereof, are supporting standards 29 and 30 provided with spaced lugs or projections 29 and 230 upon which the layers of loops may rest and whereby also the same are kept in spaced relationship. The coils are heated by a suitable burner 31.

Although in the drawing I have shown the layers of loops as spaced apart to a substantial degree, I have shown the same thus spaced for the purpose of more clearly illustrating the arrangement of the coils or loops, as in practice the layers of loops are more closely nested and the spacing lugs more closed disposed. It will, therefore, be understood that the particular degree of spacing or nesting of the layers can be arranged to suit requirements.

It will be noted that the inlet starts at the upper portion of the heater and the water runs downwardly so that incoming water will be first heated at the lower portion of the tubing, and thus the water is heated from the bottom upwardly to the top or outlet. 1 have found in practice that by this arrangement undue condensation is avoided. It will also be noted that by my arrangement of the layers of coils or convolutions a comparatively large heating surface is provided, as substantially all the parts are exposed to the heat. Furthermore, it will be seen (Fig. 2) that the respective loops or convolutions of one layer are staggered relatively to the loops of the adjacent superposed layers. This arrangement leaves no flues and air currents are consequently broken up. Furthermore, great economy of space is provided. In heating coils provided with continuous vertically arranged spirallike convolutions, air currents or drafts are more apt to take place than in the construction which I have shown and described.

Within the cas- Having now described my invention, what I claim and desire to secure by Letters Patcut is: A water heater comprising a casing, a burner arranged therein, and a water pipe leading into the casing near the upper end, projected laterally, then downwardl and laterally adjacent the burner, and projected upwardly therefrom in a series of superimposed layers extending across the casing, each layer inclining upwardly from the in- "let ,end'thereof to the outlet end thereof,

each layer including a series of successive Copies of this patent may be obtained for five'cents each, by addressing the v Commissioner of Patents,

coils, the lowermost section ofeach coil being on an upward incllnatlon with respect to the uppermost section" of the adjacent coil toward the inlet of the particular layer, whereby the flow of water throughout the layers is continuously against the action of gravity. 7 -V A v Signed at New York city, N.
