Crematory vacuum cleaner

A crematory vacuum device comprising:

• a rigid tubular handle having a conduit therethrough for connection to a source of pressurized air;
• a central fitting comprising a vacuum eductor and fixed to the rigid tubular handle at an inlet, the central fitting thus receiving pressurized air at the inlet to discharge air away from a suction head connected to the central fitting and extending downwardly therefrom, such that said discharged air draws air from the suction head, the central fitting having a cylindrical interior surface defining a vertical longitudinal axis with respect to the cylindrical interior surface;
• an expansion pipe connected to the central fitting above the suction head, the expansion pipe having an internal frustoconical expansion chamber which extends from an inlet area having a center to an outlet area having a center, which an expansion chamber axis is defined extending between the center of the inlet area and the center of the outlet area, wherein the expansion chamber axis is tilted forwardly from the central fitting vertical longitudinal axis and away from the rigid tubular handle, wherein the expansion chamber increases in diameter as it extends upwardly away from an inlet of the expansion pipe at the central fitting to an upper outlet;
• a cap which is connected to overlie the expansion pipe outlet;
• and
• a filter assembly engaged with portions of the cap and retained by the cap such that air flow from the expansion pipe passes through the filter assembly and the cap, the filter assembly thereby retaining particles above a selected size while allowing particles below the selected size to pass through, wherein the expansion pipe is tipped away from the rigid tubular handle such that the air flow is discharged through the cap in a direction having a horizontal component away from the rigid tubular handle.

• and
• wherein portions of the suction head define a lower lip which surrounds a suction head inlet, and wherein an unobstructed passageway is defined running from the suction head inlet, through the central fitting and the expansion chamber to the filter assembly, the unobstructed passageway providing a reversible pathway for particles brought into the device through the suction head inlet, such that when pressurized air is no longer supplied to the central fitting, particles engaged with the filter assembly may drop down through the unobstructed passageway to exit the device at the suction head inlet.

A crematory vacuum device comprising:

• a rigid tubular handle having a conduit therethrough for connection to a source of pressurized air;
• a central fitting connected to the rigid tubular handle at an inlet, the central fitting having passageways therein which receive the pressurized air introduced at the inlet and direct it to produce a region of lowered pressure within the central fitting;
• a suction head connected to the central fitting and extending downwardly therefrom, such that said region of lowered pressure draws air from the suction head, and wherein the suction head has a lower inlet through which air and particles are drawn into the device;
• an expansion pipe connected to the central fitting above the suction head, the expansion pipe having an internal expansion chamber which increases in diameter as it extends upwardly away from an inlet of the expansion pipe at the central fitting to an upper outlet;
• a filter assembly engaged with the expansion pipe and retained therein, wherein air flow from the expansion pipe passes through the filter assembly and particles above a selected size are retained against the filter assembly, while particles below the selected size may pass through the filter assembly;
• and
• wherein an unobstructed passageway is defined running from the suction head inlet, through the central fitting and the expansion chamber to the filter assembly, the unobstructed passageway providing a reversible pathway for particles brought into the device through the suction head inlet, such that when pressurized air is no longer supplied to the central fitting, particles engaged with the filter assembly may drop down through the unobstructed passageway to exit the device at the suction head inlet.
