Application filed February 527, 1911.' Serial No. 611,035.

'of the inventiomsnch es will enable others skilled-in the arrete which it eppertains to Ineke and use theSeme. i

My invention has -ior its object to provide un improved tank heater es eeielly adapted for use in connectionl with ict Water tanks of the type used to supply het waterfor kitchens, `but-h und similar purposes.

To such ends, the invention consists of the novel devices and combinations of devices hereinafter described and defined, in

the claim. .c

, The invention is illustrated in the single View ofoccompenying drawing'. The hot water tank l, is shown us supported by legs l and is provided withA o cold water supply pipe 2 sind o hot water dise churge pipe 3, seid ports being of standard construction.

The so-celled boiler muy take various torms,.but us preferred und us shown in the drawing. it is in. the form of o copper .coil 4l that surrounds the lower und outer end portionsof the water conduit tube 5 that exti'rtls'iaxiully through the bottom of the tank 1 und is, ot course, yconnected to the .su-id tunk bottom by o witter tight ljoint.

The lower Yend'ot they tube. 5 is closed ybut the 'upper end thereof is connected to the lower end of the hot water delivery pipe -6 that extends. ,nearly to the top of the tank. This water conduit tube 5 is divided into two compartments or chon-v toni.

nels 5 und 5", by moons of an oblique or diagonal partition 7. This partition 7 eX- tcnds from u. point considerably above and to point considerably below the tank bot- The channel 5a is the cold water re turn. channel, while the channel 5b is the hot Writer delivery channel, und itis importent to note vthat the oblique `pertition 7 makes. both of these channels or inl creuse in cross-section in the direction of the iow'of water therethrough. s shown,

vthe oblique partition -both'at its upperand lower extremities is ri idly secured tothe walls of the tube 5.--v 'lie upper extl'omit'.y

ofthe channel 5 is in' communication wit the bottom of the tank by a port 8 formed in one wall ,of the tube 5. The boiler coil 4 at its lower extremity is-tapped Iinto or' connected to the lower extremity 'of the cold water return channel 5, Whereas,theupper extremity of the saidcoil is tapped into or connected tothe lower portion ofthefhfotv water delivery channel 5?.v

The numeral 9 indicatesedrain pipe which leeds from the bottom 'of thechannel a normally closed valve, not shown, The numeral 10 indicates a," gosehurner located below the lowerendfthetube 5 and, asshown, supportcdby a door .bracket 11. This burner 10 is shown'as ,provided with e valved gas or oil Vsupply pipelQ; J'

The numerai 1'3 indicatesa, housingor hood whichis attached to thetube- 5` and .5% and, in practice, Will b3ltr-"WMM 'with incloses the boiler coil 4 so that the heat Patented sept. 3, 19'12.'

from the burner "10 will be eve'ntuully ap-'fz plied to the seid coil.

Obviously, the circuletlon of the walterheoted in the coil 4 will be upward through the conduits 5* und 6 to the top of the tank, 1

ond from thence, to the bottom of the'tenk und downward through the conduit 5. By inc-reusing the cross-section, and hence, 'the conducting capacity ofthe conduits 5'L und 5" in the direction of the flow of the'water therethrough, danger of blocking .by ,the collection ot sediment is avoided and better circulation ot the water through the tank is maintained As shown, the cold water return and hot water delivery channels of the-'tube 5 are increased in cross-section und in conducting capacity in the direction ofthe flow of the walter therethrough.

What I claim is:

The oombiniitionwith a water tank, off u boiler located below thesume, a tube ezt-,l y

tending from said boiler upward into the V`1` seid tank and provided with; Jen oblique longitudinol partition dividing the` 'saidgv l Itube into cold Water returnavnd loot-Water,

delivery ehannels, both connecting the Sa-Iid hoilerfand the said tank for the circulation VovthehWaterv of the tank therethrough, the

said -.-.fehanne1s bein increased in crossv `seetio and eonductmg capacity in the dle'et'in of the ow of the Water therethrough.
