GAS HEATEB. i

Application led Augnst 13, 1921. Serial No. 491,934.

To all lwhom 'it may concern:

Be it known that I, EDGAR E. WAYLEs, a subject of the King of England, and a resident of Et t Hartford, in the county of Hartford and State of Connecticut, have invented a new and Improved Gas Heater, of which the following is a specification.

My invention relates more especially to that class of gas heaters employed for heating fluid, and an object of my invention, among others, is to provide a heater of this type that shall be economical in the use of fuel, and particularly eiiicient in the results produced in operation.

One form of heater embodying my invention and in the construction and use of which the objects herein set out, as well as others, may be attained, is illustrated in the accompanying drawings, in which- Figure 1 is a view in central 'vertical section through a heater embodying my invention.

Figure 2 is a view in horizontal section on a plane denoted by the dotted line 2-2 of Figure 1, looking down.

1n the accompanying drawings the numeral 5 indicates a jacket, preferably consisting of double walls with a filling of non-conducting material, as asbestos, between them. The jacket is supported on a base including a side wall 6, a bottom plate 7 and a cupshaped top plate 8 within the ange 9 of which the lower edge of the jacket rests. rlhe bottom plate 7 has a central opening 10 for the admission of air to aid combustion, the tubular extension 11 forming walls of said opening, in fact, comprising a burner that is supplied with gas through holes 12 from a gas chamber 13, annular in form and supplied as from a supply pipe 14. The side walls 6 also have, preferably evenly spaced thereabout, discharge openings 15 through which excess heated air may escape, and through which, under certain con` ditions, free air may be admitted, as shown by the arrows in Figure 1.

A cone shaped flue 16, inverted, overliee the burner, above referred to, said iiue having a collar 17 located within a`flange in the top plate 8, the collar fitting within said fiange closely enough to hold the flue in place, but at the same timeloose enough 'to permit movement for adjustment purposes. By this adjustment the flue may be so located as to control both outiow .and inflow through the openings 15, in which case the heated air and fumes will pass out at the top of said openings and the free air w1ll enter at the bottom portion of said openings. An ,upturned lip 18 may be formed at the bottom edge of the lueand a `ilange 19 may be secured to the outer sur- .face of the cone shaped flue, saids lip and flange providing grooves extending around saidue. f 1

Dlscharge openings 20 areformed through the top plate` 8 through which openings the heated air and fumes from the heating chamber 21 within the jacket 5 escape to the chamber within the base, from 4 which chamber a portion or all of said gas and fumes may be returned upwardly through the flue or a portion of which may be discharged through the openings 15.

An inlet head 22 is located at or near the bottom of the chamber 21 with a water supply pipe 23 extending thereinto, said head having a neck 24 extending through the.

side of the jacket 5.

A coil 25, or preferably a plurality of coils, are connected with the head 22 and extend upwardly within the jacket, said coil or coils being' spaced from the inner wall of said acket, and as shown in Figure l of the drawings. Another and inner coil 26 has its lower end connected to a ni ple 27 xtending from the side of the hea 22, and all of the coils just mentioned are connected to a discharge head 28 in the same manner that they are connected to the head 22, said heads being substantially duplicates each of the other. An outlet pipe 29 is connected to the discharge head 28, this outlet conducting the heated fluid to i such point as may be desired.

The coil or coils 25 are placed in contact with each other so that a tube with substantially solid walls is formed by said coils, while the successive turns of the coil 26 are separated. In this way the heated air travels upward through what may be termed a flue formed by the coil or coils 25, while such air may circulate freely between and around the turns of the coil 26.

The coil or coilsbeing spirally arranged the top and bottom edges of the iue formed by said coils are inclined and, therefore, to level such edges, that is bring all parts thereof into a plane located at right angles yto the axis of the flue, I provide equalizing collars 30-31 on the bottom and top of said flue whereby the air is caused such moisture being consumed by the heat from the burner.

In accordancewith the provisions of the patent statutes I have described the prin# ciples of operation of my invention, to ether with the device which I now consi er to re resent the best embodiment thereof; but I desire to have it understood that the device shown is only illustrative, and that thel invention may be carried out by other means.

y I claim- 1. In a burner of the type described, a burner bodycomprising a horizontal bottom plate and a vertical tubular extension formmg a burner face, and a cone-shaped flue disposed above the burner and adjustable relative to the burner for varying the Langman:

distance therebetween, and av inclosing the burner and having air in ets controlled by adjusting the cone-shaped flue.

described,` a

, disposed above the burner and justable relative to the burner for varying the distance therebetween, and a casing inclos the burner and having air inlets controll by adjusting the cone-shaied ilue, and means carried by the coneaped flue for the collection of moisture for diverting moisture 'from the burner.

3. In a burner of the 'type described, a burner body, a conical flue above the burner, and an upwardly directed tubular extension carried b the flue with the conical wall of the flue aving 'the majlpr portion thereof disposed outwardly of t e burner body.
