Truck having equipment for on-site heating and collecting used grease from containers

A waste grease truck for on-site dump-collecting used, deep-fry grease dumped into a large vat-like grease container which comprises:

• a chassis;
• a large tank secured on said chassis,
• said tank including a large chamber having an openable top thereon for receiving grease dumped into said vat-like grease container and a small open-top chamber separated from said large chamber by a transverse partition,
• said small open-top chamber being larger than said vat-like grease container and adapted to receive water therein and for receiving and heating said vat-like grease container to loosen grease therein to enable pouring the grease therefrom into said large container chamber,
• means in said small chamber for heating water received therein to form a hot water bath,
• said large chamber including heating means therein for heating contents therein to facilitate drainage,
• a parallel pair of arms each pivotally secured at one end to said chassis on opposite sides of said large tank with each arm of said pair having a free end,
• a winch bar rigidly interconnecting, and journaled in, said free ends of said arms,
• said winch bar having winch spools affixed to its ends adjacent said arms,
• a reversible hydraulic motor for rotating said winch bar in opposite directions,
• cable-like elements coordinately windable on each of said winch spools for lifting and lowering said large vat-like grease container relative to said arms,
• coordinated hydraulic cylinders secured at one end to said chassis and at their opposite ends to said arms so as to swing a vat-like grease container supported by said arms to a desired position relative to said large tank,
• said openable top of said large chamber being operatively connected to said arms for automatic opening and closing in response to movement of said arms by said hydraulic cylinders, and
• means on said vat-like grease container and on said parallel arms which cooperate to dump the contents of said vat-like grease container into said large chamber,
• whereby said cable-like element ends are connected to opposite sides of said vat-like grease container for lifting said vat-like grease container, said arms are moved so that said vat-like grease container can be lowered into said small open top chamber in which the grease in said vat-like container is partially melted, then the vat-like grease container is lifted and the arms moved to a position so that the grease can be dumped into said large chamber by movement of the arms and tilting of the vat-like grease container by said means on said container and said arms that cooperate to dump the contents of said vat-like grease container.
