OIL RANGE AND TANK A 2 Sheets-Sheet 2 Filed Dec. 13, 1946 Patented June 16,` 1953 Cecil E. Chesser, Hebron, Ohio, assignor to Newark Stove Company, .Newark, Ohio, a corpora Vtion of Ohio 'A Appucationnecemtris, 1946,'seria1No. 715,991

The present inventionrelates to domestic cooking ranges and more particularly to an improved oil supply tank and support therefor.

The principal object of my invention is' the provision of an improved oil'supply tank Iand support therefor-which is safe and convenient to use and which isecient in operation and durable in service. c

Other and furtherfobjects and advantages of my invention will become apparent from the following-description.

For a better understanding of the present invention and the manner in which the foregoing objects have been carried out, reference will now vbe had to the accompanying drawings and t the -f following detailedl specification in both of which like reference characters Idesignate correslzaondn ing parts throughout and in which,

Fig. 1 is a perspective View of a combination gas and oil kitchen range with the frontal door panels ajar;

Fig. 2 is a transverse sectional view through the fuel oil tank and is taken approximately on line 2--2 of Fig. 1; and

Fig. 3 is an enlarged'front elevational view partially in section and is taken on approximately line 3-3 of Fig. 2.

By referring to Fig. l the observer will note that the combination oil and gas range herein contemplated consists essentially of a conventionally rectangular enclosure having side walls II, each lined with sheet metal with an intermediate lling of insulation material. The back wall may be correspondingly constructed and provided with elements to join with the side walls II and I2, after the manner of conventional assembly methods, so that the three wall sections denne an overall rectangular enclosure resting upon a supporting base I5.

The top of the range is comprisedU of a gas burner plate section designated I1, and an oil burner plate section designated I8, the latter of rwhich includes the removable discs I9 and 2I which overlie the oil burner units so as to aiord accessibility thereat for occasional repair, replacement, clean-out, or emergency lighting.

The front panel whichY is coextensive with the range width is designated-24 in Fig. 1 and in its surface may be noted the oven opening 25, the

storage and fuel tank opening 2B, .the broiler opening 21 and the service opening 28 to the fuel oil valve apparatus. For aesthetic reasons, panel 24 is recessed slightly or in other words, is situi ated in a plane behind the control panel 29 which 'carries the gas burner control knobs 3l to 35, Fig.

., 1 claim (o1. 12s- 44) 2 l l, the oil burner control valve drum dials 36 and 31, and the direct or starting damper control knob v38. Correspondingly', there are provided sectional door elements of a thickness corresponding 'to this recess or difference in plane levels, for covering each ci the front panel openings, aforedescribed. These include the wing doors tI and 42, the oven door i3, andthe broiler door` 44 which abut each other edgey to edge during closed position.

5 Attention will now be directed more particularl'y to the oil burner features of the present invention. A supply of fuel oil is carried in a cylindrical closed tank 1I, Figs. 1, 2 and 3, which is supported in a horizontal position upon a sheet metal saddle structure also referred to as a sump and designated 12. Thesump is a shallow open tank defined by the end -walls 13 and 14 which have the curved nesting flanges 15 conformto the transverse curvature of the tank 1I and the inwardly bent side walls 15 and 11 which together the tank 1I passes through openings 8| in a cylindrical spring housing 82 when the Valve head 83 is depressed by the tank projection 84 pressing against the spring 85 and thereby leaving an escape clearance where it otherwise engages the valve seat 86 of the flange tting 81.

As the quantity of fuel oil in the sump reservoir 12 becomes consumed and is withdrawn through the feed pipe 88, the level 19 will recede but to an extent only which will permit replacement air to enter the tank 1I through the valve seat opening. The replacement air which bubbles through the supply of uid in tank 1I permits a portion of the uid to flow out through the same opening and raises the level 19 to its sealing-off condition as aforedescribed.

When the supply `o1 oil in tank 1I is exhausted the tank may be removed for replenishment from its nested position on the sump 12 by rotating counter-clockwise as viewed in Fig. 3. This operation can be manipulated with the aid of the `pivoted handle 89 whereupon the threaded nipple 9| together with its carried valvefittings will clear the flared curvature portion 92 especially provided for this purpose and the tank 1I may thereupon be withdrawn forwardly or towards the operator, Fig. 1. The amount of fuel supply within the tank 1I may be continuously indicated upon the loat recording dial 93 which is visible when the Wing door 42 is ajar. To replenish the liquid fuel in the tank 1I the screw cap or fitting 81 may be removed by unscrewing from the nipple 9| and replenishing fuel poured into the tank 1I until lled. After this the cap 81 is restored. When the filling operation has been completed the valve head 83 urged by its spring 85 will seal the opening by seating against the valve seat curvature 86 and the tank may be reinstalled 'by reversing the 'aforedescribed removal procedure, that is to say, by rotating clockwise instead of counter-clockwise until the flange tting 81 abuts against the limit bracket 94 whereupon the head of valve 83 will then again be aligned above the embodiment 84, permitting the liquid to flow downwardly into the sump until it attains its sealing level.

The fuel oil which is supplied through pipe 88 is conveyed rearwardly of the oven, flowing gravitationally whereat it is controlled hyY a of feed supply Valves preferably of the `needle type which are contained within the tubular er1- closures 98 and 99 that encase the needle rods 41. The upper ends of the needle red 4l carry the aforedescribed drum type dial heads 36 and `31. When the valves are Qnened the fluid snnnly frem the oil reservoir will be distributed to they burners to an extent or level which corresponds with the fuel level in the sump 12.

While the present invention has been explained and described with reference to a spic embodiment it is to be understood nevertheless, that numerous modifications and variations may be incorporated Without departing from the essential spirit or scope thereof. It is accordingly not intended to be limited for an understanding of the invention to the detailed disclosure in aecompanying drawings,nor to the specic language in the aforegoing description, but to be accorded instead a latitude` of interpretation as afforded by the hereinto appended Gleim.-

The invention claimed is:

In a kitchen range in which a frontal panel is provided with a rearwardly extending fluid fuel storage aperture of predetermined width dimensions, the combination with a sump tank oomprising a relatively shallow horizontally disposed rectangular basin having fore and aft walls with uppermost edees formed inte circular nesting flanges and inwardly eenvergine sidewalls which together with said fore and aft walls form a seating perimetry for a cylindrical closure cover Vto said sump tank, a bottom wall to said sump tank having a valve actuating protuberance with an inclined approach surface and a valve engaging abutment element, of a removable reserve liquid fuel supply storage tank of cylindrical conformity to coincide with the circular curvature of said nestingv flanges and of length to overlie said fore and aft sump tank walls and thereby to constitute a closure cover to said sump tank, a protuberant valve housing jutting -axially of said storage tank and located longitudinally on its cylindrical wall in a position to register with said sump tank bottom wall protuberance and abutment element, 'an inwardly depressible spring loaded valveheadcontained in said valve housing 'having a portion outwardly extending so as to. be engaged by and depressed by said bottom wall protuberance when said storage tank is retated while nested. in seid tere and dit supportine. flangesv ene of said sinne tank side Wells remote from seid botten; Wellebntrnent element being fenned wtn en intermediate aperture in transverse registration with seid beidem Well abutment so that when said storage tank is reteted in its nesting denses seid valve housing may be passed clear of said sump tank side wall.
