6 Claims.
This invention relates to a liquid fuel burner and particularly to a liquid fuel burner for use in stoves, ranges, water heaters and other heating appliances.
The invention has for an object to provide a novel and improved construction of liquid fuel burner in which provision is made for regulating the flow of the liquid, such as oil, at a rate commensurate with the consumption of the oil while in operation and also for priming the burner or burners independently of said regulation so as to provide a unitary oil feed regulating and priming unit.
A further object of the invention is to provide a novel combined regulating and priming unit which may be interchanged with the regulating fitting of existing burners to enable conversion to be made at minimum expense.
With these general objects in view and such others as may hereinafter appear, the invention consists in the novel construction of the liquid fuel burner, in the combined regulating and priming unit, and in the various structures, arrangements and combinations of parts hereinafter described and particularly defined in the claims at the end of this specification.
In the drawing illustrating the preferred embodimentof the invention, Fig. l is a plan View of an oil burner embodying the present invention;
:Fig. 2 is a front elevation of the same; Fig. 3
is a cross section taken on the line 33 of Fig. 1; Fig. 4 is a cross section taken on the line 4-4 of Fig. l, and Fig. 5 is a sectional plane view of a portion of the priming unit shown in Fig. 1.
In general, the present invention contemplates a liquid fuel burner having the usual feed regulating unit including the individual needle valves for regulating the flow of the liquid fuel, such as oil, to each burner section and in which a priming unit is also incorporated to form a combined regulating and priming unit to thereby enable such unit to be interchangeable with the standard fitting used on the range oil burners on the market today.
In practice, in the operation of the usual oil burner commonly used in kitchen ranges, it is necessary to open the needle valves and leave them open for a period of from five to seven minutes to prime the burner sections before the latter can be properly ignited. As is well known, the needle valves in this type of oil burner for regulating the flow of the oil to the burner sections are usually throttled to the rate at which the fuel is consumed by the burner and this period of time is necessary in order to permit a sufficient amount of oil to flow into the burner sections before the same can be properly ignited.
Provision is made in the present oil feed regulating and priming unit for by-passing a quantity of the fuel beyond the needle valves and for pumping a priming charge of fuel directly into the burner sections. The priming unit includes a pump which is arranged to draw a quantity of the oil from the main reservoir and to discharge the oil thus withdrawn directly into the burner sections, thus eliminating the time interval usually necessary to wait for the liquid to flow through the needle valves.
Referring now to the drawing, the present invention is herein illustrated as embodied in an oil burner having an inlet pipe Ill leading from a reservoir, not shown, into a feed regulating unit l2. In the normal operation of the oil burner, the fuel is permitted to pass through the passageway l4 and through the needle valves l6, l8 into the conduits 20, 22 respectively, leading to the individual burner sections 24, 26. As herein illustrated, provision is made for withdrawing a charge of the fuel from the passageway M and for by-passing the fuel thus withdrawn directly into a burner section. The priming unit is preferably included in and is integral with the regulating unit I 2 and as herein shown, includes a pump having a cylindrical section 28 set into a portion of the regulating unit and a plunger 30 slidingly fitted within the cylinder 28. The cylinder is enclosed at its upper end by a cap 32, which is provided with an opening through which the plunger rod 34 is slidingly fitted. A handle 36 is provided on the upper end of the plunger rod and the lower end of the plunger comprises the usual leather piston member 38 having a metal backing member 4i! and a securing nut 42.
When the plunger 30 is raised, the fuel is arranged to be drawn into the body of the pump through an inlet 44 leading from the passageway l4 and past the ball check valve 46, normally operative to seal the opening. A stop member 48 prevents the ball from being drawn out of its repository 50. When the plunger is lowered the fuel is arranged to pass through an outlet 52 leading from the bottom of the pump, which directs the liquid into a passageway 54 and through a horizontally arranged spring pressed ball check valve 56. The liquid flowing past the valve 56 is forced through a passageway 58 to a valve member 60 which is arranged to permit the fuel to pass to either of the burner sections 24, 26. As herein illustrated, see Fig. 5, when the valve member 60 is turned 45 degrees in a counterclockwise direction, the oil may pass through the passageway 62 and into the conduit 22 leading to the burner section 26. When the valve is turned 45 degrees in a clockwise direction from the position illustrated in Fig. 1, the oil passes through the passageway 84 and into the conduit 20 leading to the burner section 24. As clearly shown in Figs. 4 and 5 the two way valve member Bil comprises a cylindrical body portion 65 having opposed out out areas 68, 10 which are arranged to connect the passageway 58 with either of the passageways 62, 65. when the valve is opened.
In the operation of the device, when it is desired to start the oil burner, the needle valves I6, I8 are closed and the plunger 39 is then raised to draw in the priming charge. The valve member 68 is then opened to permit the passage of the fuel upon the down stroke of the plunger to whichever burner section it is desired to prime. The operation may be repeated to prime the remaining burner section whereupon the valve member !50 is closed and the burner may be lighted and controlled by the usual needle valves [6, l8,
From the description thus far and by reference to the drawing, it will be observed that the present invention provides a convenient method of priming the burner sections and the present combined regulating and priming unit may be used to replace the standard fittings now in use on this type of oil burner, thus enabling existing burners to be converted at minimum expense. It will be apparent that any suitable means may be employed to regulate the volume of the priming charge, such as by an adjusting collar, not shown, mounted upon the plunger rod 34 within the piston chamber to limit the upward stroke of the piston. It will also be apparent that the construction of the two way valve 60 may be modified to permit the fuel to pass to both burners at once if desired.
While the preferred embodiment of the invention has been herein illustrated and described, it will be understood that the invention may be embodied in other forms within the scope of the following claims.
Having thus described the invention, what is claimed is:
1. In a liquid fuel burner of the character described, in combination, a source of fuel supply, a burner, a conduit leading from the source of supply to said burner, a regulating device including a needle valve in said conduit for controlling the flow of the fuel to the burner and a priming device formed integrally with said regulating device disposed between said source of supply and said needle valve and means adapted to withdraw the liquid directly from the source of supply and to by-pass the liquid around said needle valve and directly to the burner.
2.
