2Claimsh (c1.25'1-229) The present invention relates to certain new anduseful improvements in ways and means whereby cold water, direct from a city'main, is delivered to a so-called stand boiler and heated and 'made ready for tap water or for other domestic consumption purposes in the home and elsewhere.

More specifically, the invention has to do with novel v adapter-equipped pipe means which is adapted to be installed in a stand boiler at the time the latter is manufactured and made ready for use, saidpipe means embodying a water circulating and heating coil and having ways and means at its opposite ends whereby one end may be joined up with the cold water supply connectionand the other end joined up'with the hot with the regular water supply; that, in addition,

scale accumulates on the interior sides of the boiler with the result that, at times of extraordinary heat, the sediment and'silt as well as the scale are severely disturbed and roiled up, with the consequence that the domestic supply of water is frequently and uriagreeably clouded and muddied. The ordinary boiler hereinunder consideration is a typeshown, for example, in a patent'ito one John Neukam 1,775,208 of September 9,1930, whereinit will be seen that the usual cold water pipe enters the top of the boiler'an'd has its lower end terminating in spaced relation above the bottom of the water and that the hot water take-cit pipe is connected to the dome or top of the boiler, various ways and means being employed for heating the water which is delivered into and circulated through the boiler to the hot water take-off pipe.

One'object of the invention is to remedy the statedsitu'ation regardless of theamount of silt,=""

mud or scale accumulation within the boiler and regardless of the intensity of the heat applied the water within'the boiler, the usable tap water passing through a circulating and heating coil behereinafter set forth.

. 2 and onto the take-off connection and'remaining as clear and drinkable as cold water coming direct from a water main to a tap.

I Another object of the invention has to do with the heating of'water for domestic consumption,

by passing the samethroughspecial pipe 'ineans which is embodied in the boiler and which in corporates a heating coil, thus bypassing the cold water from the coldwater connection to the hot water take-off connection while at the'sametime sending it through the coil and subjecting the coil to heatingby other water in the boilerfthe tap 'water not being permitted to intermingle or mix with the heatingwater in the boiler.

, Another-object of the invention is to employ the stated construction to the end that the water contained in the boiler and supplying the heat to the water which passes th'rough'the coil means remains practically constant and intact. at all times so that no appreciable amountof the same at anytime finds its way into the coil means and thereafter through the outlet for domestic consumption. a Y .More specifically, the invention has to dowith the stated construction wherein the water passing through the coil for domestic consumption is entirelyindependent of and never mixes with the water in the boiler supplying the heat with'the exception of the aforementioned unappreciable amount which is forced, through expansion from thegboiler, into the .coil means in 'a manner to Then, too, the inventionhas to do with the stated'association of a simple coiled pipe construction with the cold water and hot water connections in a standard type storage boiler wherein the water (1) in the boiler with very slight exception'remains constant and not dissipated, its function being to merely furnish heat for (2) the'usable water passing through the coiled pipe 'means and wherein, upon cooling and contracj These andancillary objects and structural features of merit are attained by this invention, the preferred'embodiment of, which is'jset forthfin ings, a tank or boiler I is illustrated and is formed with :a convex --upper end l2 formed with a pair of'internally threaded openings l4 and I6.

Inlet and outlet pipes I8 and 20, which are vertically spaced, extend laterally to the side wall 7 of the tank and a drain valve 22 is provided 'at the lower end of the tank. An air vent 24 is provided at the top I2 of the tank and is' in' stalled between the openingsrthe air vent being provided so that the tank may be completely filled with water.

A cold water supply conduit or pipe 25 is provided -with a iconventional pressure relief valve :structure 28, which is installed .in the pipe, .the pipe being threaded into an elbow connection .30 which "is formed adjacent its opposing end with :amannular flange 3-2. The opposingend is ex iternally threaded, as at 34, and is .secured within the aopening the :flan'ge abutting vagainst the protruding wall of the :opening but seating thereton'. asz'seen in Figure 2, to provide :a .tight con,- nection. The inserted end of the elbow connec- -:tor is-internallythreadedto receive :the threaded end 36 .of --a nipple 38. The nipple 3% depends .from the inserted=end-of the elbow connector and extends downwardly in the tank.

iAxhot water outletzpipe 40 issecured by an I (elbow connector 42 through the-opening .l-4,,a coil 14 being connected at its upper send through .the lopeningl4and-being disposed vertically within the :tank. 'The coil passes into .a vertical .pipe

:166 which formed -withan axially enlarged upper send flythe enlarged end 48 being concentrically 'disposed about, the lower end of the .nipple I38 and being formed with an inwardly tapering upper end 50, which is suitably secured to the nipplebelowthe enlargedsection EZthereof. The

'enlarged :end 48 :of the ,pipe :is .formed at its ad- ;jacent \upper end 50 with radially disposed, on- .cumferentially .spaced openings 54. v

- .=In use, .heated water is disposed within the .tank .on the .outsideof the coil Mand the pipe 46, the .water being carried 'to1thetank or boiler by the inlet pipe and'being heated by any suit- .ablemeans. The water in the pipeand-coil, the pip '26 being directly connected to the water main, is heated 'on passing through the coil. The boiler accumulates large quantities of sediment 'on the'bottom thereof I and scale 'formations o'ccur on the sides of the'boiler. At times, due to .a "high temperature of the water, the scale :and sediment :deposits v are agitated and stirred up. But .the purpose -of zthis invention :is totprevent the water within :the-boiler, having scale accumulations therein, ffrom passing through the coil and-to theoutlets and yet .to allow the water to expand ,and', contract. Thus, :as the water .in the boiler aexpands, it flows through -the apertures in vthe-end 48, but the amount of water that will .actually enter the tubing -or coil, even .at high temperatures, will be slight and will not afiect ethe condition of the water supply. Upon .con-

traction of the boiler water, the pressure of the 4 water in the water main will force fresh water through the openings in the end 43 into the boiler.

The only purpose of the air vent located on the top of the boiler 24 is to facilitate the initial filling; it has no other function. The pressure relief valve 28 is conventional and is merely installed for cases of exceptional pressure in such emergency that the back pressure from the water main might be such to cause destruction. These features are conventional and the inventor claims no art so far as they are concerned.

As above stated, water in the boiler is to remain constant and unchanged with the exception of that slight amount which might 'be expelled through expansion, this being accommodated by the apertures at the top of the coil 48 and hence in a downward direction to the bottom and passing out through the coil along with the water for-domestic consumption. Specifically, note that the waterpassing through the coil for domestic consumption is entirely independent of and never mixes with the Water in the boiler supplying the heat with the exception of the aforesaid unap- .preciable amount which is forced through .ex- ,pansion from the boiler .into ,the tubing .through apertures 34 as aforesaid. It follows then-that (Althewater in theboiler, with this veryslight exception, remains constant and not dissipated,

.its function being to merely furnish the heat for (B) the usable water passing through the coil means. Upon cooling and contraction, the .pressure in the stand boiler decreases and the water main pressure will automatically force water back through the same apertures keeping the boiler .filled =ata1l times.

Having described the :invention, whateisv claimed as new is:

1. In a structure for handling, storing and heating tap water which is free from :rustand sedimentation deposits and substantially :.as :pure

and euncolored as if delivered -=directly from .-a

supply main comprising, in combination, rastand tank having a cold watersupply piperconnection at its top, a hot tap water deliverypipe connection also at its -top, and pipemeans being confined in said boiler and communicatively con- .nected at one end withvsaid .cold water pipe connection and-connected at its opposite end with said hot water pipe connection and provided intermediate its .ends with heating coil .means, .said pipe means conducting the .incoming cold water directly to said latter pipe connection by way of said coil means, whereby to prevent said water from intermingling with other water in ports, Wherebyany. small amount of water necessarily expelledfrom the boiler, b expansion from .heat, will flow through such openings and pass through the coil and coil outlet along with the water from the main inlet to the consumption taps, and upon contraction of the boiler water the pressure of the water in the cold water main will cause'fresh water to flow through'saidports,

automatically replenishing the boiler.

2. For use in a stand type boiler which includes a water containing and storing'tank for heating water and which has a 'domical top, a

cold water supply'pipe connection mounted said top and a hot water pipe take-off connection also mounted in said top, and wherein said connections are internally screw threaded, means for circulating water directly from one connection to the other comprising an adapter nipple adapted to be screwed into the cold Water connection and to depend therefrom into the boiler, a second adapter nipple adapted to be screwed into the remaining hot water connection and to depend into the boiler in spaced parallelism to the firstnamed adapter, pipe means having one end portion coiled and connected with the second-named adapter and having the opposite end portion linearly straight and terminating in a ported enlargement, the first-named adapter nipple being adapted to extend concentrically and in spaced relation into said ported enlargement.
