To all 'whom it may concer/n:

Be it known that we, HARRY D. FTNBEEG, a citizen of the United States, residing at Roxbury, in the county of Suffolk and State of Massachusetts, and SAMUEL S; LEVY, a subject of the Czar of Russia, residing at Dorchester, in the county of Suffolk and State of Massachusetts, are the joint inventors of a new and useful Improvement in Heaters, of which the following is a specification, like numerals referring to like parts throughout the several views of 'the drawing. Y

Y This invention relates to heaters and pertains more particularly to water heaters applicable to gas ranges, oil ranges, electric ranges and the like and adapted to be interposed between the flame or heated area and a cooking or a culinary vessel. e

In carrying out the objects of our invention, the embodiment thereof in its preferred form, includes a system of tubular water containing members distributed in an efficient and effective manner about the heated area of a gas or other iiame preferably combined with a casing adapted in its construction to present lunits thereof or a unit construction.

In order to illustrate said invention,'we have shown in the accompanying drawing one embodiment thereof wherein: i

Figure 1 is a plan view of a heater and casing of the invention.

Fig. 2 is a central longitudinal section on Fig. 1.

.Fig 3 is a similar section illustrating a modified form ofcasing.

Fig. 4 is a transverse section on line 4 4 of Fig. 2.

Fig. 5 is a similar transverse section on line 5-5 of Fig.. 3.

Fig. 6 isV a detail in perspective of a heater shield. Y

Fig. 7 isatransverse section of said de tail. .Y

The terms employed herein are used in the generic and descriptive sense and therefore'are not intended primarily as terms of limitation.

In the drawing, 10 represents a rectangular box like frame Vprovided with the depending side members 11 and end members 12 and 13 each having therethrough a series of "arched openings 15 or other openings adapted to permit of the circulation of air beneath the casing. The top face 16 of the said casing may be integral with the aforesaid members as in Figs. 3 and 5, or as 1n F1gs. 1, 2, and 4, the upper portion of the said casing may be provided with a flange 17 upon which rests or upon, which is secured the top or hot plate 18. In the case of the latter` construction, the said hot plate may be provided at one end with a pair of lugs 19 adapted to extend beneath and em brace the lower face of the flange 17 and the opposite end of said plate maybe provided with one or more latches QOadapted to be moved into and out of position beneath the iange 17.

This latter construction allows for the removal of the top or hot plate 18 for the purpose of permitting an inspection, cleaning, or repairing of the heater or the tubular members hereinafter described.

Whether the said hot plate 18 is integral with the casingor detachable' therefrom it is provided with circular openings 22 surrounding which arev depressed flanges 28 adapted to receive thereon'a cover 24'of any suitable or preferred type. .v l

Said covers may consist of the usual type of plain stove cover 24 or any suitable modification thereof consisting, for example, ofa plurality of concentric ring like members one nested within the other each adapted to present an opening of a different diameter above which opening or within which may be set a cooking vessel or the like.

In its preferred embodiment, the heater Vand casing consists of a unit like construc-r tion or any multiple thereofadapted to eX- Vtend over or across two or more burners of a gas or other range. In other words, the heater is adapted in its dimensions to extend across two or three burnersV of a range of the type mentioned. If additional heaters or heating surfaces are required another heater of similar type is placed over and across adjacent burners rof said range. The casing is preferably providedv with as many `covers and cover holes as desired or the units supplied thereto and impart s ame as near equally as possible to allY portions of 'said heater. Y

For this purpose we provide an inlet pipe adapted to be coupled to the bottom level of a hot water storage tank or the like for domestic purposes from which said inlet 25 4passes through an opening through the end member 12 and extends to a point adjacent to theen'd member13. Near the end member 13 the said pipe is Vcurvedat a-'wide radius to bring the same close to and paralleling the side member 11 to form the coil 26. VThe' coil 26 is ata slightly'higher level thanV the inlet pipe 25 and extends to the end member .12 where it is curved in a wide radius to form a coil 27 extending along and parallel tothe lside member 11 opposite the location of coil `26. Near the end member 13 the coil 27 is curved in a wide radius and joinsthe coil 28. The coil 27 is at a slightly higher level than the coil 26 and thecoil 28 is at a still higher level than the preceding coils until itV reaches the end member 12 where it is curved and joins with the coil 29' at astill higher level. It will now be noticed that the coils 28 and l29 are interposed between thecoils 26 and 27 in their respective order and are nearer the longitudinal center ofthe heater. The coil 29parallels the coil 27 to a point near the end member 13 where it is curved to join the outlet coil 30- at a still higher level'tha'n any of the preceding coils and close to and parallelto the inlet- 25. Said outlet Vpasses through an opening in the' end member 12 where it is coupled to the aforesaid hot water storageV tank at a much'higher level than the inlet' 25. Thus the incoming water flows through theinlet pipe 25 along the center of the flame heatedarea from thence it is branched out to the sides of the heater farthestl removed from the inlet from which its succeeding convolutions `or, coils approach the Ycenter of said flame heated'a'rea.` at continu- Y ing higher levels, after which the Vheated,

water is conveyed back to the hot water V storage tank 'along the center of the heated ternately by the heater coils to enlarge asV ,area and in a position parallel and next adjacent tothe inlet. n Y

Therefore, the ila-me Vand heat vabout the heated areaof a gas range are deflected al far as possible the actual heating area. The respective positions lof the said water containing coils also tends to radiate the heat fromadjacentcoils to the coils containing the water at a lower temperature and therefore it is a principle of our invention to apply the heatas uniformly as possible throughout thefentire extent of 'the said coils. p Y Y The coils being ofthe thinnest tubing necessary lto withstand the water pressure,

take up the heat unitsV very rapidly, and

with the wide radius of the bends between vadjacent coils permit of rapid and unobstructed circulation. By meansV of coils Aof lthis type, leaking joints and couplings are dispensed with so that a much stronger coil structure is obtained. Also the wide sweep-Y ing radius at which the coils are joined one to the other' best enables the metal tubing to be bent without undue straining or thinning of the metal along the outer portion of the curves and is best adapted to withstand the expansion of the' coils or any tendency to straighten.

InV order to support the respective coils,

we provide a plurality of Vbrackets 32 extending from near rone side ymember llto a point near the other and provided with saddle portions 3.3 the latter being so ar- V 'theulug 34. On the other hand, if the removable hot plate is employed the said .bracket 32 may be integral with the side members 11.

llntegral with the removable hot plate 18 is arcorrespon'ding bracket'3'8 having saddle portions 39 corresponding with the saddlerportions of its V'co-acting'bracket 32, in

rorder that when 'all the members hereinbefore mentioned are assembled, lthe coils being located ,within'the said saddle portions will be retained thereinior held thereto preventing displacement of the latter from any cause whatsoever. In Fig. -5 the bracket 38 Y is separate and bolted at lOto thebracket 32.

Vhile the brackets 32 may correspond in shape to the transverse contour of the respective coils and thereby permit for as much circulation of air within thecasing 10 as may be possible nevertheless, it is desirable and preferableV that Y. Ythe respective brackets shall be as open as possible to permit of kfree vcirculation of heatfrom theV heated area. Therefore between .the saddle Vportions`33 and 39, the said bracketsare provided with openings 41 and in addition other openings 42 may be had through the said brackets enabling the air and the heat to circulate freely from one portion of the casing 10 to another. y v. Y

interposed rbetween the heating means,`

flame, or the likeand each of the heater coils is a guard, deflector, or'the like 45 of trough like circularv construction bowed or bent longitudinally or to Van angular form from end to end thereof as illustrated in i Fig. 6. Therefore the center or central portion of said guard or deflector abuts the` coil to which it may be secured by means of the ears 46 crimped or bent about the coil. Therefore the ends of the said guard are removed or separated from the coils to permit of the circulation of heat and air about the coil. In this manner, the flame is prevented from coming into direct contact With any of the coils of the heater permitting, at the same time, of the free circulation of heat throughout the extent of said coils. Said guards furnish means for taking up heat units applied thereto during the operation of the heater and re-radiating the same both to the coils and a cooking vessel located above a cover hole 22. When the gas or other flame is extinguished the said guards being in a heated state, Will like the adjoining pipes re-radiate their heat to the pipes and assist in maintaining a circulation of the water for a period longer than the operation of the said flame.

F rom the entire construction, it will be seen that every advantage is taken toconfine the heat -units to the coils and to the cover plates, thereby taking advantage of a large loss heretofore dissipated and overcomes in a very large measure the uneconomcal operation of gas or other ranges at present employed.

The entire casing l0 may be secured to the range or the like in any suitable or preferred manner. For example, herein illustrated in Fig. l, are lugs 50 at each corner of the frame 10 through Which lugs any suitable or preferred fastening may be inserted to clamp the frame 10 to the range in position above the burners 5l or other heating medium. Likewise it will be seen that inthe employment of a unit construction as herein set forth that no alterations, reconstructions or. adjustments of the present types of ranges are necessary in order to adapt the invention to such range.

In its application, the invention is adapted not only to heat Water in al storage tank, or the like, for future use, but is also adapted for all other culinary purposes to which a gas or other range may be utilized. Cooking utensils of every kind and,l description may be placed above the cover holes 22 with or Without removal thereof and said utensils Will be heated in the same manner as heretofore. On the other hand, by employment of the coil, the heat is not only deflected and distributed evenly throughout the heater but heat units heretofore lost by the use of an open llame or the like is utilized to transfer said heat losses to Water to be stored for future use.

The openings 15 in the frame 10 permit of sufficient circulation of oxygen to allow a gas, or the like, to burn with a clear blue flame which is directed upwardly and spread out over a much larger area than is the case With the open flame.

By constructing the casing with a removable hot plate, access can be had at all times to the coil and to the interior of said casing for the purpose of cleaning the same or making any repairs that may be necessary from time to time.

We have described one embodiment of our invention; but it is to be understood that the latter is not essentially limited to the specilic details of construction and organization of said embodiment, since the same may be varied Without departing from the proper scope of the claims.
