Specication of Letters Patent.

Patented Aug. 11, 1914.

Application filed November 12, 1913. Serial No. 800,594.

The general objects of this invention areto.` of heat generated byv promote the efficiency a usual gas burner, and increase the utilization of the said heat. And to these ends the invention consists of a star-shaped burner provided with a water-back, whereby heat escaping at the sides of the burner will radiate around the said water-back and so heat- .the water contained therein.

Other objects will appear and be better understood from that embodiment of my-invention of .which the following is a specification, reference being had to. the accompanying drawings forming part hereof, in which Figure 1 is a top plan view of the device. Fig. 2 is a horizontal cross section taken on the line 2-2 in Fig. 3. Fig. 3 is a vertical cross section taken on the line 3-3' in Fig. 1. Fig. 4 is a vertical cross sectional view taken at right angles to Fig. 3. Fig. 5 is a fragmentary top plan view of a modification of the face of the device.

rlhe'device, indicated in the drawings by a is constructed of one' piece and thus may be formed of ,cast iron. It is adapted to be used individually and can be also mounted in a usual gas range and form an element thereof.

Centrally located inthe device e is a webburner 5 having on its upper surface the usual perforations 6 for the ignition ofthe gas. rihis burner is fed by a supply pipe 7, which is provided with the mixing chamber 8 for introducing the necessary air for pressure on the flame. The usual air pocket 9 is provided at the center of the burner; the plate 5 (see Fig. 4) may be detachable if desired for the purpose of cleaning the device when necessary.

In concentric spaced relation with the periphery of the burner 5, is the wall 10, which cooperates with the wall 11 of the burner in forming the water-chamber 12. This wall 10 is provided at the inner side with inwardly-directed radial arms 13, which are directed between the branches :1 4 of the burner 5; the reason of these an d,

being so positioned will be hereinafter fully explained. l

'At a suitable location .on the wall .10, shown inthe drawings at the rear, is an extended portion 15 for connection with the water-pipes 16 and 17, and separating the pipes in the interior of the water-chamber is a wall'18. The pipe 17 is the inlet or cold water supply pipe and being located adjacent Ato the iioor 19, directs the water along the bottom of the lchamber 12. As the water becomes heated adjacent to the top of the chamber it passes 'out through the outlet or hot water pipe 16; this-pipe is located adjacent to thetop portion 20 of the heater, and connects the water chamber with the storage tank (not shown).

As shown in Fig. 1 the upper face 2O of the chamber 12 is provided with concentric corrugations 21 and 22, which coperate with a vessel placed on the burner to pocket the heated air and increase the efficiency of the llame. It will be noted that a kettle or a like vessel would rest upon the usual grating (not shown) located abovethe burner,I thus permitting a space to remain between the. bottom ofthe kettle and the crest of the cor rugations; and the heat arising from the -llame in the burner 5, will radiate along the bottom of the kettle and passing over the corrugations. will be pocketed therebetween.

Lugs 22 are provided at the bottom of the device and function as legs for the same.

As shown in Figs. 2 and 4, the lower portions of the chamber at either side, are concaved as at 23. These concave portions run vparallel with the longitudinal axis of the device and are substantially straight in ,direction These concave portions are pro- `pipes may be accommodated v vided so that at the sides of the device and fit; inugly against the same. This is essential in the case where a series of the burners or heaters are mounted on a gas range, which has a limited surface'space. And so that the pipes connected to the rear burner will not conflict with the front burners, the concave parts allo-w' the pipe to pass as shown in dotted lines in Figs. 2 and 4.

A modification of the top surface 2O is shown in Fig. 5. In this case the corrugations are radially' disposed and allow the heated air to pass over the corrugations and so heat the water in the chamber.

In operation the devit j nay be used singly or collectively as hert itt-:fore stated,

v loer at 2d (see Fig.. 3) and circulates around to the tank or boiler.

' acetylene gas non7 used. in a larve number and as the outlet pipe 1S is i* loe adapted to use lont is especially7 dapted to be fitted in a gas range. The pipe 7 is connected. to a gassupply pipe not shown, and the inlet Water pipe 17 is connected. to the cold Water supply pipe. ALikewise the pipe 16 connects the Water chamber l2 with' the storage hot-water tank or boiler. The Water enters the chamthe branches 'of the burner., The plates 13 direct the Water in a zigzag motion, and as the Water travels it becomes heated by the 4heat-Waves radiating along the top surface 20 of the 'Chambon It will be seen that the upper portion of the Water Will be heated located uppermost the heated Water passes therethrough lt is to be understood that the orner may natural or artificial gas. llt may be adapted also to use the usual.

o-farnis and dwellings. a

lt is obvious that those skilled in the art may vary the details of construction and arrangements of parts Without;v departing from the spirit of my invention and therefore do not wish to be limited to such fea `tures except as may be required by the claims.

What is claimed as new is: 1l. 1n a devieeo the class described, a burner and a wetter-heating' chamber formed Y arms of the bur integral therewith, the top portion thereof hai/ing concentric corrugations ot dilferent heights substantially as described.

'l 2. En a device of the class described, a burner having radial arms, a water-heating chamber surrounding the burner and formed integral therewith, and delectors positioned on the inner peripheral wall oit' the chamber so as to direct the water into between tbc ner for the purposes set forth.

3. A. combined gos burner and Water heater, comprising :in oifter casing adapted for connection to an inlet pipe and an outlet pipe and forming the outer wall ot a water chamber, a burner proper disposed centrally of the casing and provided with radial arms forming the inner wall of the water cham ber, said Water chamber being interiorly divided into communicating compartments,

and said outer casino; being formed with radially` disposed bullies arranged in staggered relation with the arms of the burner and cooperating with the said arms for the purpose set forth.

In testimony whereof I aix my signature in presence of two Witnesses.
