AUXILIARY WATR, HEATER.

Appiicatin filed March i4, 1927. seal no; 175,342.

This invention, generally stated, relates to an auxi'liaryjvater heater arranged toV be supported within the fire pot or combustion chamber of a furnace, stove, or gas heater, y and has more especial relation tothe typeV factured under the patent aforesaid too quickly passes tothe 'element to be heated, as for instancea radiator, with the result that-'full efficiency of the auxiliary water heater is not obtained;

The leading object ofthe present invention is "to overcome this disadvantageous feature and provide fan auxiliary water` heater of the character stated in which the radiating hollow branches ofthe Iauxiliary water heaterare so arranged that cooled water as returned to the auxiliary water heater is battled, deflected, and retarded sufficiently to beconiemore oi' less heated from the furnace,'stove or gas heater prior to its being` delivered to vthe yelement to'be heated,

Y Y s pipe having screw-threaded relation with the upper nipple 2. ,The upper endof pipe Y as for instance a radiator.;l y l Y Y n A further'object'of thepresent invention resides iii the provision of va baille plate hav'- ing radiating extensions, .the general configuration of the baffle plate being somewhat star shaped,ithe extensions of said battleA plate eitherv having the edges thereofintegral with or closely fitted againstat least a portion of the side walls of each of Vthc radiating branches'of the heating chamber of said auxiliary water heater.

lVitli these and. otherobjects in view, the invention consists of the novel construction hereinafter described and finally claimed.

The nature, characteristic featul'res Yand scope of the invention will be morel fully understood from the following` description taken in connection with the accoinpanying drawings forming part hereof, and i in which: l i

Fig. 1, is a view in vertical section of the auxiliary water heater.

For the purpose ofzillustrating.my invention Il have shown inl they accompanying drawings one form thereof which fatpresent preferredby ine, since the samehas been 'Y found"inpracticeqto give satisfactory and reliable results, .although 'it is to. ,be under,-v stood that the variousinstrumentalities ofA which my invention yconsists .can be variously arranged andorganized andthatmmy invention is notlimited to therprecise arrangement .and organization .of the instrumentalities. as hereln shown :and described.

Referring now to the drawings in detail,`

the reference numeral' 1 .designates a. water heating chamber, ,preferably formed ofy cast inetaland provided-top andbottom with in` ternally threadednipples 2-and 3 respectively. Thesenipples 2 and 3 are centrallyarranged andV radiating therefrom yare a plurality of hollow branches Li These hollow branchesA 'i 4fl in Veffect .providea generally star shaped water heatingchainber as best seen in Fig. 3.`

supported by a pipef5,the .lower endl ofy said 5 carries a connect-ion G for the passageot heater water to a suitable heating element` as a radiator, not shown iii the drawings. The bottom of the water heating chaniber 1.

as shown in Fig. 1, is closed by a plug 7. Ar-

ranged witliin pipe is a pipe S connected for the return of cooled water to the water heating element 1,' the ksaidpipe 8 being spaced from the walls of pipel 5. The pipe 8,1as clearly shown, projects into the heatingv vextensions 9 of the baille plate extend Well along the respective hollow branches and p formed integral with the side walls ofthe-hollow branches or closelyfitted Vagainst the'side walls thereof, as is very clearly shown in Fig. 3. This arrangementof parts provides a baffle plate of maximum area so that cooled water being returned through pipe 8"is balied or retarded temporarily so that the said water may be more etliciently heated than it is in the auxiliary water heater mentioned in the patentafore said. Retarding or battling the cooled water as returned to the water heating chamber so that said water may be additionally heated adds materially to the eiiiciency'of the auxiliary. water heater since when the water is additionally heated as by my present device, the heater water passing to connection 6 obviously has thevtendency to bring the waterpassing through pipe '8 to a higher temperature than ispossible in the aforesaid patented device.

If it is desired to extend the heating surface of tlie heating'chamber 1, a lpipe or water leg 10 may be screw-threaded into the lower nipple 3, as clearly 'shown in Fig. 2, anda plug 11 secured to the bottom of pipe l0. In this' case an extension 12 is secured with respect to pipe 8 so that the water being returned from a radiator is directed to the bottom of the water leg 10. v

In Fig. 5, a furnace 13 is shown. which may be of any particular type and to which my novel form of auxiliary water heater is applied.

It will be noted in the connection that all of the ligures illustrate a." Water heating chamber in which the baille plate extensions 9 terminate short of the outer ends of the hollow branches of the water heating cham* ber. Thus, considered in plan, as clearly illustrated in Fig. 3,' relatively circular openings 14 are provided in each hollow branch ofthe ywater heating chamber for the vpassage of water tothe pipe 5. p

`t will now be apparent? that I have devised a novel and useful construction which embodies the features of advantage enumer ated as desirable in the statement ofthe in*k vention and the above description and while I have in the present instance shown and described the preferred embodiment thereof which has been found in practice to give sat- Vlsfactoryl and reliable results, it' is to be un,- derstood that the same is susceptible ofl modification in various particulars without departing from the spirit or scope of the invention or sacrificing any of its advantages. l

Having thus described niy invention, what I claim as new and desire to secure by Letters Patent is: Y Y 1. A device of the character stated, comprising a water heating' chamber having a branches and closelyA engaging'- the side YwallsV of said branches, an inlet pipe for convey- Y ing eooledwater to thebottoin of said Ichamber and an outlet pipe surrounding saidtirst.

mentioned pipe for the. exit Yof heated water.

2. In a device of the character stated, comprising` a water heating` chamber having' a plurality of' radially extending' hollow branches, a baffle plate arranged within said chamber, said plate having extensions equal in number to and coincident with said hollow branches, said extensions extending into and terminating short of the outer ends of 'said branches and closely engaging the side walls of said branches, the ends of said. extensions andthe ends of said branches, considered in plan, forming' relatively circular openings, an

inlet pipe for conveying cooled water to the e bottoni of said chamber, and an'outlet pipe surrounding said first mentioned kpipeA for the exit of heated Water;
