My invention relatestoheaters of the storagetype and. itv especial reference to a means for mounting the tanks of such heaters to facilitate their removal and replacement.

Water heating unitsof present day, construction consist generally of'a'hot water storagefreservoir suitably insulated or containedrwithin and secured to an insulating jacket. Owing to the-union between the tank and acket, it is extremely difiicult, time consumingandexpens'ive to dissociate or dissemble, the tank from the organized heater, and this cannot be done-by anyone save a skilled'w-orkman, i

, The objects of'the present, invention there- }pfovide a mount-for tanks of heating, units which the tanks may, after making the disconnections with gas and water lines, be readily removed without disturbing the insulation or causing any other annoyance. v Another objectof the invention is to provide a means in connection with the tank of a water heater whereby such tank may be readily locked in place within or to the insulation or insulating jacket and unlocked so that the removal of the tank may be possible. I j f s Another object of the invention is to provide a heatinggdevic'e ofthestorage type in which the tank is supported in. such wise th'at'its entire area is exp'osed to the heat from the burners. l,

These and other objects areaccomplished by an arrangement expressed in preferable form in the drawing which forms a part of this specification and inwhich- Fig. l an ,elevational sectional view showing my invention,

In a generalsense, the. invention consists in mounting or supporting a storage tank within a shell, preferably an insulatingijacket in such wise and inannerthat it may be quickly dissociated or removedlfromr the jacket or insulating envelope by anyone withoutthe exercise of any especial skill; it'also consists of the novel relation of the water tank to the jacket'byreas'on of which all the heat from the burners oriothersource is utilized in heating the water in the tank; and finally it consists of the specificj means by which the ready association of the tank with and its dissociation from itscomplementary enveloping insulation may be effected.

In its specific aspect, the invention as shown in the drawing comprisesawater heating unit of the type known in the art as storage heaters, in which the water' is heated by any heating mediumiand stored until used, and such water heating unit consists principally of a storage tank and insulating jacket 2, and such other instrumentalit-ies, not shown, as'are generally complements of Water heaters, and which foriningno part of this invention, need nodescription As seen in Fig; 1, theinsulating'jacket 2 consists preferably of'two spaced shells '2 and 2", conjoined in'suitable manner'to form a single unit and the insulating unit envelopes the tank 1 at the sides and top thereof being spaced therefrom a distance sulficient to provide for a free circulation of the heat around the tank. The top of the insulating jacket 2is provided with a'hollow not shown, to lead ofl'the gases of combustion from thespa'ce between the tank "andfjacket. "Centrallypf the top, the insulating jacket 2'is provided with an opening 4 for the accommodation of the insulating shell by spaced; outwardlyl and" downwardly bent over a fitting 7 that is threadedly connected lar 5 is arranged to be secured upon the fitting 7 so that the flange 6 thereof is in engagement with the horizontal portion of the inner shell2 of the jacket 2. When the sleeve or collar 5 is in the-position,- shown in Fig.1, the tank 1 is rigidly locked against movement relatively to'the top of the jacket 2, and it will beobvious that such relative movement of the tank 1 may be effected by releasing 5' unscrewing the set.

the collar or sleeve The tank'l is supported within and free of a series of equally members 12 'whic are welded or otherwise secured to the tank 1 near thebottom thereof.

' These" outwardly" and downwardly bent members 12 co-operatewith outwardly bent and the "insulating' acket 2, in

upwardly extending members 131 which are preferably riveted to theinner'shell, 2 of supporting the tank 1 withinthe jacket. Oneofthe outwardly and upwardly extending members, namely 14, is constructed to'co-act with its complementary member 12 in locking the tank 1 in position and preventing movement of same in a, circular direction and a consequent accidental disengagement of the mutually engaging memb ers 12,13 and 14, by reason of which the tank1 would no longer be supported. 1 For this purpose, the member at central recess .14"

-movement with the tank lateral projections 14" 14 'isprovided in the upper edge thereof with for the accommodation of one of the outwardly "and downwardly bent members 12, which afterbeing seated in the recess 14' is restrained against circular 1 by the upstanding provision of the recess 14 on fastened .tothe. fitting 7, thereof in engagement with the top portionof the inner insulating shell :2. In this position,the tank-1 issecurely Hheldwithin the jacket 2 against'any movement. When for any reason it is desired or 5 top of required to remove the tank 1 from the jacket disconnections being first made,-the-collar or sleeve 5 is unlocked from 2, the required pipe vated the a tank having a fitting at the to tending through the top of sai and one of'said movement the bottom of sai resulting from the in the member 14. 1 Fig. 1, the 'm'embersf12' on the tankl fare shown in engagement with the members '13 and member 141 a collar or. sleeve 5 is with'the flange 6 the jacket, and the height sufficient to causeone of the members 12 thereon to disengage from the recessed acket 2, and during this member 14 on the elevation of the tank 1, jected beyond the jacket 2.

the fitting 7 is procient to cause the members 12 on the same to be moved out of alinement with the members 13 and 14 on the jacket 2. Thereupon the tank 1 may be withdrawn from the jacket 2.

What I claim, is: v f e r 1. In a waterheater, an insulating jacket,
