Cartridge-type oil tank construction

A cartridge-type oil tank construction comprising:

• an oil tank means having an opening formed at the portion of the upper wall thereof in the vicinity of one side end thereof;
• a tank supporting means detachably mounted through said opening with respect to said oil tank means and having an oil supply port formed at the side portion thereof;
• a cartridge tank having a valved cap, said cartridge being invertedly supported on said oil tank means through said tank supporting means so that oil is fed from said cartridge tank through a valve of said cap and said oil supply port of said tank supporting means to said oil tank means;
• said tank supporting means comprising a portion engaged with said opening of said oil tank means, an inner vessel downward extending from said engaged portion and provided with a filter means and an actuating means for actuating said valve of said cap of said cartridge tank and an outer vessel downward extending from said engaged portion to surround said inner vessel with a space being defined between said inner and outer vessels so as to act as an oil reservoir;
• said oil supply port comprising an opening provided at the side wall of said outer vessel;
• and,
• a positioning means comprising a projection provided on said outer vessel of said tank supporting means so as to extend from said engaged portion to the vicinity of the lower end of said outer vessel of said tank supporting means and a cutout formed at the periphery of said opening of said oil tank means, said projection and cutout being engaged together to position said oil supply port of said tank supporting means so that it faces the other side end of said oil tank means opposite to said one side end thereof when said tank supporting means is mounted with respect to said oil tank means;
• said oil tank means further including a chamber provided at the outside of said tank supporting means for receiving a volume of oil sufficient to allow an oil level in said oil tank means obtained when said oil tank construction falls down in the direction of said one side end of said oil tank means to be substantially lower than said oil supply port of said tank supporting means.

A cartridge-type oil tank construction for an oil burner comprising:

• a stationary tank arranged to laterally extend from a burner body of said oil burner and having an opening formed at the portion of the upper wall thereof in the vicinity of the distal end thereof;
• a tank supporting means detachably mounted through said opening with respect to said stationary tank and having an oil supply port formed at the side portion thereof;
• a cartridge tank having a valved cap and invertedly supported on said stationary tank through said tank supporting means so that oil is fed from said cartridge tank through a valve of said cap and said oil supply port of said tank supporting means to said stationary tank;
• said tank supporting means comprising an upper flange securely supported on the periphery of said opening of said stationary tank, an inner vessel downward extending from said supported portion and provided with a filter means and a push pin for actuating said valve of said cap of said cartridge tank and an outer vessel downward extending from said supported portion to surround said inner vessel with a space being defined between said inner and outer vessels so as to act as an oil reservoir;
• said oil supply port comprising an opening formed at the side wall of said outer vessel;
• and,
• a positioning means comprising a projection provided on said outer vessel of said tank supporting means so as to extend from said flange to the vicinity of the lower end of said outer vessel of said tank supporting means and a cutout formed at the periphery of said opening of said stationary tank, said projection and cutout being engaged together to position said oil supply portion of said tank supporting means so that it constantly faces said burner body of said oil burner when said tank supporting means is mounted with respect to said stationary tank;
• said stationary tank further including a chamber provided at the outside of said tank supporting means for receiving a volume of oil sufficient to allow an oil level therein obtained when said oil burner falls downs in the direction of said distal end of said stationary tank to be substantially lower than said oil supply port of said tank supporting means.
