HEATER.

Application tiled November 6, 1922. Serial No. 599,474.

My invention relates to improvements in heaters, andmore particularly to that type lor class commonl knownaswater heaters.

The primary o ject of the invention is to provide a generally improved heater of the class indicated which will be exceedingly cheap of manufacture, andeiicient in use. t

A further and very important object is the provision of an improved heater flue or coil .for such heaters throughfthe provision of a novel construction and arrangement of heater coils and bailie forming loops communicating with the combustion and l1 uid circulating chambers, respectively. Y

ore s ecitcally stated, my improved heater `Hue em odies a plurality of superposed linkshaped coils providing 'convolute gas assages and intermediate transversely e ongated or iattened hollow loops forming baffles for diverting the` products of combustion into and throu h said gas passages of said link-shaped -coi s," said ybailie forming loops communicating' with the' water or liquld chamber of the surrounding heater body.

A further and -very important object is the provision of an improved or heater body and coil `having its parts and features of construction so disposed and arranged relative to each other` that the same may be cast of suitable metal as a one-piece article of manufacture, thereby resulting in greater' economy in manufacture, use and eiiciency. vA still further object is the provision of a one-piece or cast heater provided with a liquid circulating chamber' and an intgral orm heating flue and having an improved and arranrrement of clean-out door at one side ail'or ingaccess to the water chamber \\an il/,exterior portions ofthe heating Qflue orl With the above mentioned and other ends in view, the invention 'consists in the novel v construction, arrangement and Combination of parts, hereinafter described,illustrated in ,e one. 'of its.. embodiments in the accompanying drawings, fand particularly pointed out like 'parts throughout all the figures of the drawings.

The improved heater body 1, may be of any suitable and', convenient form that adapts itself to be readily cast as a one-piece body and with afclean-out opening at one side if desired. In the present instance, the heater body l is of square or rectangular shape forming a liquid or Water circulating chamber la, and a subjacent combustion or burner chamber 2. In the present instance, the/heater body 1 is provided at one side with a clean-out door opening 3, of relatively large dimensions, as shown, and surrounded'by border fia-nge 4, to make a tightl or liquid sealed joint withv the door or cover 5. In the present instance, the border Harige 4 is provided with a series of bolt receiving openings Il, adapted to receive and carry a seriesof securing bolts 5, and securL infr the cover 5 in position.

rrl'he heater -iiue 6 in the present'instance is cast integral with the heater body l and extends through the water circulating chamberL 1, terminating, inthe vpresent instance, at the top in a flange 7 for receiving a suitva'ble chimney pipe for conducting the products of combustion to a chimney or other suitable outlet. top of the heater body is provided with threaded openings 8, one of which may be closed by a suitable plug and the other connected. to a suitable ,water pipe, a third threaded opening 9 being provided for a second conductory pipe communicating with the lwater circulating chamber. In the presentv instance, the heater flue 6 is .provide with an enlarged central portion 10, and a series of vertically arranged superl posed double coils 11, as indicated. y

In the present instance, the v cross water passages 12, which,respectively,`

occupy the center-portion of the superimposed convolute coils, and, in addition to their water circulation function, constitute baffles overlying the reduced neck portions of the structure which constitute the communicating vcenter passages between the respective link-shaped convolute passages. These water passages, being open at their ends, aord a plurality of cross connections leading through the flue to the water spaces on opposite sides of the flue and serve to direct currents of water back" and forth directly -through the flue structure atdiferent levels throughout the height thereof.

This arrangement insures that the prod! uets'of combustion will be repeatedly divided and alternatelyunited throughout their passage through theflue and further pro- Avides that \the products of combustion upwardly flowing in a united Acurrent through the centrally. disposed, reduced neck portions of the `flue will strike bodily against the baliling walls of the cross water passages, so that the water at several different levels will be brought intodirect contact-with the united centrally upfiowing gas stream in a manner to effectively insure the-radiation of heat units and prevent an excessive escape of suchunits from the top of the Hue.

The arrangement is one which provides not only for the'sinuous flow of the gaseous products of .combustion but also provides for a back and forth circulation of the water through the independent open-'ended cross water passages at several levels which,

tends `to permit circulationand enlarge the radiating area of the flue to a highly desir` able extent.

Having thus described one of the embodiments of my invention, without having attempted to set forth all the forms in which it may be made,or all the modes of its use, what I claim and-desire to secure by Letters Patent is,- A

1. In a waterrheater, the combination of an outer shell and an inner flue portion furnishing a water chamber betweenthe two,

. a combustion chamber vbelow the flue and freelyI communicating therewith, the' flueV being configured tolafford superposed pairs of outwardlyl protrudingl convolute gas passages separated from one another by open ended cross water passages opening into the water' chamber, adjoining pairs of convolute'gas passages being connected by intermediatemeck' portion for the passage of gases upwardly beneath the walls of the superposed cross water passage, the latter forming a baffle for diverting the up'- wardly flowing gases laterally into the convolute gas passages, and the iiue terminatformed therewith and freely communicating therewith, the l'lue being configured to af- Vif Aford supczposed pairs of outwardly pretruding eonvolute gas passages separated from one another by open ended cross water passages opening directly into the watei chamber, thepairs of eonvolute gas passages being connected by inter1nediate neck portions for the passage of gases upwardly beneath the lwalls of the cross water passages` the latter forming ballles for diverting the upwardly iiowing gases laterally into the convolute gas passages, and the flue terminating in a discharge passage leading through the water chamber'and out of the shell, substantially as described.

3. In a water heater,4thecombination ot' an outer shell and an inner flue portion furnishing al water chamber between the two. a combustion chamber below the flue and freely communicating. therewith, the liuc being configured to afford superposed pairs of outwardly protruding convolute gas passages separated from one another by open ended cross water passages opening into the water chamber, the pairs of convolute gas passages being connected by intermediate neck portions for ,the passage of gases up wardly beneath the walls of the cross water passages, the latter forming baffles for diverting the upwardly flowing gases laterally into the eonvo'lute gas passages, and the upper pair of convolute gas passages uniting in a discharge passage leading upwardly through the water chamber and out of the shell, substantially as described.

4. In a water heater, the combination of an outer `shel1 'and an inner integrally'r formed fine portion furnishing a water chamber between the two, a combustion chamber below the flue and integrally formedv therewith and freely communicating. therewith, the flue 'being conligured to af ford Snperposed pairs of outwardly protruding convolute gas passages separated from one another by open ended cross water passages" opening directly into the water chamber, `the pairsof convolute gas pas-l sages being connected by intermediate neck ortions for the passage of gasesupwardlyr beneath the walls of the cross water passages, the--latter forming bailles for divert'- ing` the upwardly flowing gases laterally into the convolute gas paages, and the upper pair` of convolute gas passages uniting ina discharge pass e leading upwardly through the wat-er ber and out of the shell, substantially as described.-

5. In a water heater, the combination of an outer' shell and an inner in formed line portion a water chamber between the two, a combustion chamber Ybelow the ilue and. integrally formed therewith and freely communica therewith,l the flue being configured to a ford superposed pairs` of Youtwardly -protruding convolute passages separated from one another'by open ended cross water ture passages opening directly into the water ward p'bemg connected by' intermediate unobstructed n'eck rtions. for the passage of gases upwardly neath the downwardlv conver walls of the cross water pase latter fo upper pair of convo ute gas passages uniting in a discharge pleading upwardl through. the water chamber and out of 30 t efslxell,` substantially as described.A
