' r This invention relates to a water heater'and more particularly to a water heater in which 011 is used as the fuel. I

It is the general object of the invention to provide a new and improved hot water heater.

Among the objects of the present invention are: to provide a novel and improved heater of the character referred-to; to provide a novel arrangement of oil burner and associated parts for heaters for heating water and the like; to provide a novel mounting for the oil burning pot; and the provision of a novel combination of an air inlet opening and plunger rod assembly.

Other objects and advantages will become readily apparent from the following detailed description taken in connectionwith the accompanying drawings, in which:

Fig. 1 is a vertical longitudinal centralsection through a heater embodying our invention, parts being shown in side elevation for clearness.

Fig. 2 is a to plan view of Fig. 1.

Fig. 3 is a fragmentary vertical central section through the lower portion of our heater and showing the structure formounting the oil burnerpot therein.-

Fig. 4 is a transverse section on the line 4--'4 of Fig. 3.

Our invention further resides in the combination, construction and arrangement of parts illustrated in the accompanying drawings, and while we have shown therein a preferred'embodiment we wish it understood that thesame is susceptible of modification and change without departing from the spirit and scope ofthe appended claims.

Referring more in detail tothe drawings our improved heater comprises a metal outer casing I mounted at the bottom upon a base 2 having legs 3, and having fixed to the top thereof a top late 4. Spaced inwardly a distance from the outer casing I is an inner metal casing 5 which is likewise mounted upon base 2 and at'its upper end is provided with the top plate 6 likewise spaced from the outside top plate 4. The space betweenthe outer and inner casings I and 5, and between the top plates 4 and 6 is filled with any suitable insulating material 'I as desired. Extending through registering openings in the top plates 4 and 6 and the adjacent portions-of the insulating material I is a tube 8 through which passes the gaseous. products of combustion from the oil burner pot later more fully described. Any suitable means (not shown) may be applied at the top of tube 8 for conducting the gasesof combustion from the tube 8 to a flue leadin o 7 Claims. (Cl. 12694) thereof a curved bottom plate I2 having a cen-.

tendingto the lower portion of the inside of the tank is a fill pipe II through which the water or other liquid to be heated is introduced into thetank. Through nipple I0 may be passed any suitable pipe or tube to conduct the heated water from the inside of-the tank to any desired place of use. I v I As seen in Figs. 1 and 3 there isprovided within the tank a distance above the bottom end tral opening I3 through which extends the bottom end of tube 8, which tube is welded or otherwise secured in watertight relation to bottom plate I2, and which plate may also be welded or otherwise secured in watertight relation to the interior of the inner casing 5. As seen in Fig. 1

the bottom end I4 of tube 8 extends a slight distance below the bottom plate I2. Secured at diametrically opposite points to the lower face of bottom plate I2 are bracket members I5 each provided in its vertical web with an opening I6 through which are hooked the curved ends I! of the hanger rods I8, which at their bottom ends are formed with threads I9 threaded over which are wing nuts 20, above which wing nuts are washers 2|. Support-bar 22 is provided at its opposite ends with openings 23, one of which for convenience in mounting is in the form of an open ended slot, through which openings extend the hanger rods I8 so that the ends of the support-bar, after the parts are assembled, rest upon the washers 2|. As will be understood the support-bar 22 is slipped over the rods I8 after which the washers and wing nuts are applied. As seen in Fig. 3 this structure constitutes a hanger or support within which the oil burner pot is mounted.

Support-bar 22 at its middle portion is formed with an upwardly extending rib 24. Positioned directly above support-bar 22 is a plate 25 formed at its mid portion with longitudinally spaced depending ribs 26, within the space between which is fulcrumed the rib 24 of the support-bar. The depth of ribs 26 is less than the height of rib 24 so as to ermit a rocking action of the plate 25, as may be required to properly position the parts during assembling. Positioned in spaced relation around the outer portion of the plate 25 are three equally spaced upstanding ribs 28, each tom' corner edge of the burner pot so as to position the burner pot with relation to the heatplate and hold it thereon. The oil burner pct 30, which is formed in it side walls with air holes 3|, is provided at its top with a top plate 32 having an annular groove 33 formed therein to be seated against the bottom end edge of the tube 8., Formed centrally in the top plate 32 is an opening 34 having communication .on its lower side with the [interior of the burner pot and having communication on its upper side with the interior of the tube 8, so that the not combustion gases may pass fromthe'interi'orof the pot to the interior of the tube 8. The combustion of these gases will be substantially :com-. pleted within tube 8 to heat the mvateror :other liquid within the tank.

In assembling the burner ;pt .in position the hanger rods 18 are first inserted by means of their hooks H in the brackets l5, which bra-ckets are each welded or otherwise secured by the angular leg 35 to thelower face-of the bottomplate 1.2. The .support-bar22 will thenbe positioned upon these hanger rods through the medium of openings ZB and the washersZl applied over these rods below the supportbar. The wing. nuts will then be threaded onto the lower'end of these .hanger rods, the heat-plate placed upon the support-bar with rib 24 in the space between the shorter ribs 26, and the burner ,pot 30 positioned within the curved recesses .29 of ribs .218. The pot top plate 32 is then placed on the burner pot with the annular flange .tt positi-oned within the upper edge of the burner pot walls, and the bottom and edge of the tube .8 inserted in groove 33,. aft.er

which the nuts will be tightened upon the g hanger rods +8 to bring these partsinto secured and tightened position. It will be understood that-as these parts are being clamped together "as described, the plate may tilt on the Support-bar as may berequired to make 'a tight joint between the bottom of tube sBand the top plate 3.2 and bring all of these parts in desiredassembled and tightened relationship. As the clamping of these parts proceeds one or the other of the nuts .20 unay be advanced faster or slower. than the other so as to afiord a proper seating of the various parts, any adjustment being provided for by the tilting .of the plate as described above.

Extending through the wall of the pot '30 .at the bottom thereof and projecting outwardly therefrom .is a ,plunger rodassembly .31 the rod '38 of which-extends through .the'opening Q39 in *the inspection-door All, .there being provided a handles .on theouter-end of the rod outside of the inspection door llLso-as to enable manipula tion of the-rod to control entry .ofoil to the interior of the pot as desired. As noted in .Fig. .3 the opening .39 around rod 38 is of substantially greater size than the-size-of the rod and handle .so asstopermit the entryzof air through hole 39 to the interior of the space 42 inuthe tankbelow -'-the tank bottom l2, to aid combustion-of the oil "within the pot rand within the tube 8, .such air passing through openings 3| in the pot walls into the interior :of the pot. As will-'beunderstood-a shallow layer of oil-will'be' present inrthe bottom nof the'pot so as to provide a large upper-surface of oil :for vaporization. JIhe pipe-T 4.3 .in the plunger rod .assembly will be'connected to any within the heater, the arrangement of parts between the burner pot and the tube 8 being such that maximum heat will be transmitted through the walls of the tube 8 to the water inside of the tank. Also it will be understood that our adjustable arrangement of parts for clamping the oil burner. pot in position at the .bottom of the :combustion tubeis suchthat the plate, due to its tiltable connection with the support-bar will automaticall bring these parts into proper position with relation to each other during tighteningfof'the nuts 2!]. A drain cook 45 is provided near'the bottom of the tank to enable draining :of athe tan-kas desired. Any well known and suit- ;able :heatmegulating means may be used as de- .ssired.for:;regulating the temperature of the water in the tank.
