WATER HEATER.

Application filed April 29, 1920. Serial No. 377,706.

1 0 all tU/LO/It 71mg; concern:

Be it known that we, Josnrrr OSCAR SMITH and JOHN B. Rnnvns, citizens of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Tmprovements in Water Heaters, of which the following is a specification.

This invention is a water heater and has for its object the provision of a heater comprising a relatively long narrow flue formin g the heating chamber and having a water jacket surrounding the same. This flue may extend the entire height of a room and form the exhaust flue for the heater without necessitating the use of extra pipe sections. The fine forming the heating chamber being relatively narrow the greatest efficiency of the heat units passing therethrough will be expended upon. the relatively thin film of water in the narrow water jacket surr0undlug the heating chamber, thereby causing the water to quickly heat; and the desired capacity of the heater may be obtained by providing a relatively long flue and water jacket.

It is a further object of the invention to provide a heater which will be of comparativelyfew parts and which may be quickly assembled, thereby preventing the liability of the heater becoming inoperative and also forming an extremely cheap construction.

Further objects of the invention will be readily understood from the following description of the accompanying drawings, in

which Figure 1 is a perspective view of a water heater construction in accordance with the invention, partly broken away.

Fig. 2 is a transverse section on the line 2-2 of Fig. 1.

The improved water heater comprises a. burner chamber 1 mounted upon a support ing standard 2 and a relatively long narrow annular water jacket 3 supported upon the burner chamber and forming a combined fine and heating chamber 1 within the water jacket. Burners are provided in the burner chamber having their nozzles arranged as a Y and extending upwardly and outwardly so as to direct the flames from the burners upwardly through the heat chamber 4 adjacent the inner surface of water jacket 3 so as to form a draft opening at the axis of the heat chamber. The burners are supplied with fuel from. a pipe 6.

Means are provided for automatically controlling the admission of fuel to the burners, this controlling-means forming the subject matter of our co-pending application Serial No. 377,705, filed April 12, 1920.

The water jacket 3 is formed of con reutric inner and outer spaced shells 7 and 8 connected at their ends by cross walls 9 to provide a closed cylindrical jacket of relatively thin width, so that a comparatively thin film of water will pass through the water jacket thereby increasing the rapid ity with which the water will be heated by the heat from the burners passing through the heat chamber 4 inside of the shells forming the water acket.

The water acket is supported at its lower end upon the burner chamber 1, preferably, in an annular groove 10 provided in the upper edge of said chamber. A second groove 11 neferably, formed in the upper edge of the burner chan'iberinside of the inner shell 7 of the water jacket, this groove being arranged receive any moisture which may be condensed within the heat chamber 4% when the burner is first started. The moisture which may be condensed within the heat chamber will drip from the wall of shell 7 into the groove 11 and will be subsequently vaporized and pass I out of the burner, thereby avoiding the dripping of water into the burner chamber.

Vvater is, preferably, supplied to the water jacket 3 through a pipe 12 comnuinieating with the water jacket adjacent its lower end and extending downwardly out side of the burner chamber to a valve chamber 13. A valve 14 controls the inlet of the water from a water pipe 15 into the valve chamber and thence into the water jacket. The discharge from the water jacket, preferably, (ton'iprises a pipe 16 communt eating with the )er end of the water jacket and extending inwardly from the inner shell 7" and thence downwardly through the heat chamber 1. The lower end of pipe 16 is coupled to a pipe 1'? extending but wardly through the shells of the water jacket. This pipe may be connected to any suitableconduit for the hot water. All of the connections, as thus described, preferab-ly threaded connections so that the parts may be quickly assembled and taken apart. The pipe 16 extending downwardly through the heat chamber is, preferably, arranged concentric to the shells of the water jacket, so that all of the water passing downwardly through the pipe maybe acted upon by the heatwithin the heat chamber to increase the heat of the Water. 7

A series of plates 18, preferably, surround the pipe 16 and extend radially therefrom to a point spaced slightly from the inner shell of the water jacket. These plates are provided with openings 19to permit the passage ot the burning gases through the heat chamber to theupper open end thereoflthe openings in one plate being staggered with relation to the openings in adjacent plates, thereby forming tortuous passages forthe hot gases through the heatchamber. The plates 18 besides thus forming b'atlies for the prottlucts oi?- combustion also form heating fins t'or'the pipe 16. Ly means of these fins the heat of the products of combustion passiiig through the heating chamber is conducted by contact ith'said fins directly to the pipe 16 for heating the Water therein.

It will be observed that the waterh ater constructed in accordance With this invention provides a relatiyely thin Water jacket surrounding; a combined flue and heating chamber of relatively small diameter, so that aquantity i Waterin the jacket may be quickly heated, the temperature of this \yater being further raised during its passage through the pipe 16 which is completely surrounded by the heating medium passingthrough the chamber By iii-airing the Water jacket and heating flue relatively long a relatively large amount of hot water may beobtained, and the heating chamber also forming the flue of the burner dispenses with the necessity of employing pipe sections to term a flue.

It'willj also beobserved that the bafiles 18 are so arranged as to prevent the products of combustion passing too rapidly through the heating chamber, whereby the greatest efiiciency is obtained from the heat units 01 the heating medium, and it will be, further noted that the bafiies 18 form efiicient heat conductors to the Walls 01? the pipe 16.

Various changes may be made Without de- 'partiiig' 'froni the spirit of the invention as claimed.

What is claimed is:

1. A waterheater comprising aburner chamber, the top ot 'said chamber having an annular groove, an annularreces's forn'ied on the upper portion of the outer wall of said groove; said recess forming an annular shoulder adapted support a Water acket formed between coh centric'shells and formfine \Vltlllll the inner shell, and the inner shell of the jacket projectin' inwardly beyond the outer" Wall of said groove and terminating intermediate the outer and inner'iyalls of said grooye.

2. A ater heater comprising "a burner chamber, the top ofsaid chamber having an annular groove and there being an annular recess"ioi'inecl on the upper portion of the outer wall of said groove 'andiorming an annular shoulder, and a Water heating jacket resting-upon the shoulder seas to leave a space in said groove below the water heating-jacket and inside of the lower end of the' Wat-er heating j acket, the inner Wall of said grooye extending above the lower end of the jacket,

In testimony whereof We have signed our names to thi's specification.
