((1126-350) This invention relates generally to tank struc tures for heating ?uids. An important characteristic of my invention is the provision of means for including in a 5 common, outer enclosure or tank a combustion chamber, a compartment for storing a supply oi’ the ?uid or ?uids to be heated, and a fuel supply compartment. ' itnother characteristic is the provision of a to compact and conveniently portable ‘structure width may be advantageously employed i'or many purposes for which a heated liquid is re ouired, as for instance in various ' cleansing _ anti/or spraying operations. l5 hnother characteristic oi my invention is'ithe provimon of such a tank assembly which is ari ‘ . ranzerl both ‘for preheating the liquid to he heated by proximity to the combustion chamber, and for the heat-insulation oi the supply oi’ incl 0 by the interposition oi’ the lluid to be heated between the loci storage compartment and the combustion chamber. _.Another characteristic is the provision oi” means for heat-insulating the upper- end of the % incl compartment, preferably by extending the compartment for the liquid to be heated over the top oi the iuel compartment. Other objects and novel‘ features of construc tion, and also of arrangement of parts, will ap~ m pear irom the following description. ’ r ‘ combustion chamber 5 forms the compartment 8, for the storage or the supply of the ?uid to be heated. ,_ t represents a incl-compartment iormed by ‘ a vertical partition it, which forms the cord of 5 an arc oi’ the perimetral wall of the tank i, by the arcuate portion of the said wall, the ?oor i2 and the top closure ii. The partition it is spaced i'rom' the perlmetrol wall of the combus tion chamber t and one oi the braces ‘i may be m interposed between the same. it represents a liquid supply pipe extending up through a sealed port in the ?oor 2 ‘and within the ?uid compartment t to a point adjacent to the top oi the latter, and it represents a valve is on the upper end of said pipe controlled by the ?oat it which is operated by the level oil the liquid‘ in level constant compartment of the ?uidt, inthus said maintaii compartment, as ‘indicated. - - > 20 As illustrated, the top ll oi the fuel com partment t is materially below the normal level oi the liquid in compartment t. Thus at all times a body oi this liquid is inter- . posed between the combustion chamber and the m5 iuel comrtment, thus preventing signi?cant heat-transference to the lucl which would cen erate dangerously explosive cases in the fuel compartment. Further insulation tor the iuel tank is pro- 30 in the accompanying-drawing, wherein I'have vided by the liquid overlying the top of the fuel illustrated a practical embodiment of the prin-w compartment, thus preventing heat-transference through the air above the body of ?uid in the ciples of my invention: lilo. i is a plan view of a heater tank assem 35 bly constructed in accordance with my present invention. Fig. 2 is a vertical section of the heater tank structure. I ‘Referring to the drawing, i represents a tanlr compartment a. There is also a consert‘a?on oi.’ heat energy 35 by surrounding the combustion chamber with the liquid to be heated. _ ( _ it represents a throat connecting‘ with the in- _ terior of the iuei compartment tor ?lling the 40 preferably constructed in cylindrical term and same. it represents the port connection through the having the elevated ?oor l which forms the upper and lower compartments 3 end i. The upper ' ?oor i for withdrawing'iuel from the compart compt 3 of the tank i is-subdivided into ' three chambers, the combustion chamber 5, the it ?uid chamber and the fuel chamber.. The combustion chamber 8 is preferably cylin clrlcal in shape and positioned eccentrically 'ot the tank i but in spaced relation with the per imetral wall the latter. The bottom oi the com " so bustion chamber 5 rests on the "?oor 2 and is se cured thereto by a ?uid-tight, sealed joint, as by welding, as, indicated at t. The combustion chamber may be supported by braces 1 extending inwardly from the perimetrai wall of the tank l. as The interior of the tank i surrounding the ment 9 tor the burner. ll represents a similar port in the bottom of the compartment 0 ‘for the withdrawal oi’ the liquid to be heated. 45 it represents a bracket or other support de pending irom the ?oor 2 within the compartment t. Upon this support the fuel and liquid pumps are mounted. The fuel burner, indicated at Ilia, is supported by the ?oor I and is centered in an 50 annular opening I! at the bottom of the com bustion chamber I. Any suitable type 0! burner may be employed, such, for instance, as is illus trated in my co-pending patent application Se rial No.v 88,106, ?led June 30, 1986. Inasmuch 55 2 2,115,587 as ‘the structure of the fuel and liquid pumps, the burner and the ‘coil or other heat-transfer means within the combustion chamber, are not and side wall of said tank, said partition spaced per se a part of the subject matter of the present application, the same are not shown. Suitable structures for these purposes are shown and de from the wall of the combustion chamber, and a, compartment formed by the partition and top of the fuel tank, the wall and the ?oor of the enclosure tank and the wall‘ of the combustion chamber for storing the liquid to be heated. 2. In a heater tank assembly, the combination scribed in my pending patent applications as follows, Serial No. 87,847, ?led June 29, 1936; Serial No. 91,405 ?led July 18, 1936, and Serial 10 No. 88,106 ?led June 30, 1936. 20 represents a frame secured to the lower end of the tank I upon which are mounted the trac tion wheels 2|. 22 represents a handle or tongue for conveniently moving the portable assembly 15 from place to place. The lower portion 23 of the tongue 22 is e}: tended downwardly to form a leg to support the assembly when stationary. I claim:- 20 the combustion chamber, a fuel compartment formed by a partition and top with the ?oor ' 1. In a heater tank assembly, the combination of an outer enclosure tank, a ?oor in said tank, a combustion chamber mounted on the floor within said tank, a fuel burner associated with of an outer enclosure tank, a combustion cham 10 ber constructed within said tank, a fuel burner associated with the combustion chamber, a fuel compartment formed by a partition and top wall with the wall of said tank, said fuel compartment .being spaced from ‘the combustion chamber, and a compartment formed ‘between the fuel‘ compartment and the combustion chamber for storing the liquid to be heated, and braces pass ing through the upper part of the liquid com partment for supporting the upper endof the combustion‘ chamber.
