The" respective sections'of the brackets'i i are prov'ided" with intu'rned flanges 9 which in;

turned flanges 9 constitute r'ests or supports forthef'heiating j tubes adapted to be sup- P t d r on-T" j' lnthepreferred embodiment, as illusig. 1,"a pair of communicating pipes 10 are employed, which communicati'ng'pip'es are provided With a plurality of spaced collars 11 for the purpose of receiv mg theoppositelythreadedends of the heating'pipes 12; These heating pipes 12 are preferably fformedhof thin metal andhave enlargedf fends 13 which are externally threaded,"as clearlyillustrated in 3 of thej drawin'ggthe' respective ends being opp'ositely threaded, asabove stated, for the purpose of permitting the heating'pipeslQ to be conveniently threaded intothe respective collars 11 formed upon the communicating pipes By carefully considering the drawing it will be seen that the enlarged roam 1 3a th he pip wil p sent a smooth surface upon the outer end thereof for permitting a wrench to convenientlygrip the pipes for the purposefof threading the-pipes 12 intothe, collars 11. The"cornniunicatingpipes 10 are provided intlfi'riie'd elbow'portions 14l, 'which are connected by end pipes 15, and these end pipes lij are similarly, constructed to the pipeslQ and are adapted to rest upon support ng flanges 9 upon the respective sections of the brackets 4, thereby constituting an efficient means for supporting the heating 7 device uponthe stove.

A,plurality of integral ears 16 are carried by the communicating pipes 10 and are arranged in spaced relation, and preferably communicating pipes 10 throughout their entire length. k j I A supply pipe 17 of suitable construction may be connected in any desired manner to one of the communicating pipes 10 and a discharge pipe 18 may also be connected to the opposite end of one of the communicating pipes 10 to constitute a return pipe, and this pipe 18 is adapted to extend back under the pipes 12, as illustrated in dotted lines in Fig. 1, and may then be brought in any desired manner to the source of water supply, or reservoir, preferably passing parallel with the pipe 17. v

Bolts 19 pass through the flanges 9 of the brackets 1, and these bolts 19 are'adapted to pass down through the bottom of the stove for permitting the anchoring of the brackets 4 in engagement with the stove, in any suitable or desired manner.

As illustrated clearly in Figs. 1 and 2 the heating pipes 12 are provided with a plurality of spaced integral beaded portions 20 formed thereon to constitute ledges upon which a receptacle orpan may be seated thereby elevating the receptacle or pan above the level of the pipes 12. It will, therefore, be seen by this that the beaded portions 20 will constitute supporting legs for spacing the receptacle placed upon the pipes away from the upper face of the pipes, as illus trated in dotted lines in Fig. 2 of the drawings.

. In Fig. 6 there is shown an embodiment of the invention wherein the transverse heating pipes 12 may be connected to individual T-joints 10, which joints 10 are in turn connected by means of a union joint 21. The T-joints 10 are,of course, provided with the integrally projecting tongues 16 similar to the tongues 16 illustrated in Fig. 1.

In the embodiment disclosed in Figs. 1, 2, and 3, it will be seen that the heating pipes 12 are arranged in parallel or multiple'relation. In the embodiment shown in Fig. 7 the heating pipes 22 are arranged in series, the respective pipes being connected by meansof the connecting elbows 23. It, of course, should be understood that the elbows 23 are provided with supporting tongues 24 similar to the tongues 16, for supporting the elbows 23 in engagement with the side rails 1 of the stove. The pipes 22, like the pipes 12, are provided with beaded portions or collars 25 arranged in spaced relation there on for the purpose of constituting supporting legs for a pan placed'upon the heating pipes 22. It, of course, should be under- Y stood that the water supply may be taken to and from the pipes 22 in any'desired Genie: 011ml patent may be obtained {or manner, such for instance, in the same manner as that described with reference to Fig. l.

In Fig. 8 there is shown a pan, which is used in connection with the present invention, comprising a rectangular body which is adapted to be inverted over the heating pipes 12 and 22 for retaining the heat around these pipes. The pan 26 may be provided with an aperture 27 to allow the heat to pass out therethrough and into engagement with a pan or receptacle placed upon the pan 26 when the same is in an inverted position.
