Claim 6

An oil burner of the class described having a non-rotating passage for delivering fuel oil through an ejection orifice, a rotary slinger cup open to said orifice for the delivery of fuel to a fire-box, a tube inserted within said passage having one end accessible for connection to a source of fuel other than that used as a fuel-in-chief and having its other end within said passage adjacent said orifice whereby the orifice of said passage may expeditiously be cleared of said fuel-in-chief, said tube being appreciably smaller in cross section than the cross section of said pAssage so as to afford a way for the flow of said fuel-in-chief.

Claim 7

An oil burner of the class described having a non-rotating passage for delivering fuel oil through an ejection orifice, a rotary slinger cup open to said orifice for the delivery of fuel to a fire-box, a tube inserted within said passage having one end accessible for connection to a source of fuel other than that used as a fuel-in-chief and having its other end within said passage adjacent said orifice whereby the orifice of said passage may expeditiously be cleared of said fuel-in-chief, said tube being appreciably smaller in cross section than the cross section of said pAssage so as to afford a way for the flow of said fuel-in-chief.

Claim 8

Apparatus for operative connection to a burner having a rotary slinger cup provided with a nozzle orifice opening into the interior thereof for heavy oil, said burner having an operating controller and comprising conduit means through which a relatively light oil may flow from a receptacle to said burner upstream of said orifice, first means to start and stop said flow, second means arranged and adapted to afford a control for connection to a valve component of said burner for starting and stopping the flow of heavy oil therethrough and timing means for interconnection with and responsive at least in part to said controller, said timer being arranged and adpated for operational connection to said first and second means to operatively control the flow of said oils to said burner for combustion in designed sequence to comingle for at least some period consequent upon a change from one oil to the other.

Claim 9

Apparatus for operative connection to a burner having a rotary slinger cup provided with a nozzle orifice opening into the interior thereof for heavy oil, said burner having an operating controller and comprising conduit means through which a relatively light oil may flow from a receptacle to said burner upstream of said orifice, first means to start and stop said flow, second means arranged and adapted to afford a control for connection to a valve component of said burner for starting and stopping the flow of heavy oil therethrough and timing means for interconnection with and responsive at least in part to said controller, said timer being arranged and adpated for operational connection to said first and second means to operatively control the flow of said oils to said burner for combustion in designed sequence to comingle for at least some period consequent upon a change from one oil to the other.

Claim 10

The apparatus according to claim 6 which further includes means arranged and adapted to afford a plurality of rates of flow of said light oil to said burner.

Claim 11

Apparatus for operating an oil burner having a rotary slinger cup provided with a nozzle orifice opening into the interior thereof and a controller for regulating the operation thereof, a source of a first fuel oil, an independent source of a second fuel oil, and means for conducting the flow of oils to the orifice of said burner comprising first electrically operated means for starting and stopping the flow of said first fuel to said burner, a second electrically operated means for starting and stopping the flow of said second fuel to said burner, a third electrically operated means arranged and adapted to afford a plurality of rates to the flow of said second fuel to said burner, an electric timing means interconnected with and responsive, at least in part, to said controller and arranged and adapted to control the flow of electric current to said first, second and third electrically operated means in a desired sequence whereby said fuels may be burned by said burner in a predetermined arrangement.

Claim 12

Apparatus for operating an oil burner having a rotary slinger cup provided with a nozzle orifice opening into the interior thereof and a controller for regulating the operation thereof, a source of a first fuel oil, an independent source of a second fuel oil, and means for conducting the flow of oils to the orifice of said burner comprising first electrically operated means for starting and stopping the flow of said first fuel to said burner, a second electrically operated means for starting and stopping the flow of said second fuel to said burner, a third electrically operated means arranged and adapted to afford a plurality of rates to the flow of said second fuel to said burner, an electric timing means interconnected with and responsive, at least in part, to said controller and arranged and adapted to control the flow of electric current to said first, second and third electrically operated means in a desired sequence whereby said fuels may be burned by said burner in a predetermined arrangement.

Claim 13

The apparatus according to claim 8 wherein said electric timing means embodies part of a circuit between the closable contacts of a heat demand responsive structure and said controller, said timing means being receptive to signal current and on receipt of such signal current, renders said controller insensitive to said structure, closes electric circuits through a plurality of relay contacts and thereby sets in motion a motorized switching organization which affords said fuel flow timing and regulating functions, and affords a predetermined time delay between the opening of said closable contacts when such heat demand has been satisfied and the transmission of the information thereof to said controller whereby said burner is afforded a post-burn flush period that is separate from its normal post purge period.

Claim 14

The combination comprising an oil burner having a rotary slinger cup provided with a nozzle orifice opening into the interior thereof suited for burning in a regulated combustion cycle a first fuel and having a source thereof and a second fuel also having a source thereof and fuel flow regulating means arranged and adapted to regulate the delivery to the orifice of said burner of each of said fuels independently of the other, said regulating means being further arranged and adapted to afford such delivery in a predetermined sequential program during selected portions of a combustion cycle whereby the quantity of soot and of air pollutants resulting from combustion characteristics of said second fuel.

Claim 15

The combination comprising an oil burner having a rotary slinger cup provided with a nozzle orifice opening into the interior thereof suited for burning in a regulated combustion cycle a first fuel and having a source thereof and a second fuel also having a source thereof and fuel flow regulating means arranged and adapted to regulate the delivery to the orifice of said burner of each of said fuels independently of the other, said regulating means being further arranged and adapted to afford such delivery in a predetermined sequential program during selected portions of a combustion cycle whereby the quantity of soot and of air pollutants resulting from combustion characteristics of said second fuel.
