Publication number: 20030003209Abstract: A cooking apparatus includes a container, a spigot, a lid, and a food support. The container has a bottom surface and a side wall that extends upwardly from the bottom surface to a top edge of the side wall. The spigot is attached to the container side wall and has a valve member that is selectively positionable between opened and closed positions. The spigot valve member allows liquid contents of the container to drain from the container when in the opened position, and prevents the contents from draining out of the container when in the closed position. The food support is comprised of a perforated horizontal member with a perforated side wall extending upwardly from the horizontal member. A plurality of vertical members spaced around the periphery of the horizontal member extend upwardly from the horizontal member.Type: ApplicationFiled: August 2, 2002Publication date: January 2, 2003Inventor: Donald P.

Patent number: 6481343Abstract: A cooking grate for a grill, such as a barbecue grill, is comprised of a plurality of generally elongate rail members assembled in a nesting relationship to form a first and second cooking surface. The first cooking surface is formed by a generally flat surface on each of the rail members, the flat surfaces abutting to form a substantially smooth surface, with a plurality of elongate apertures therein through which juices produced by cooking food may flow. Each rail member has a gutter along its length which underlies approximately half of each of the apertures for catching a portion of the juices and diverting it from the heat source below. The grate may be reversed and the gutters form the second cooking surface which is similar to a conventional grate surface.Type: GrantFiled: September 29, 1999Date of Patent: November 19, 2002Assignee: Empire Comfort Systems, Inc.Inventors: Donald P.

Patent number: 6083392Abstract: A funnel having at least one channel or groove formed by projected ribs in the sidewalls of the funnel. The projections space the sides of a filter membrane placed inside the funnel, thereby preventing the sides of the filter insert from adhering to the sidewalls of the funnel and allowing the fluid to flow through the sides of the filter insert and into the grooves or channels that conduct the fluid to the discharge orifice of the funnel. The projected ribs are preferably a plurality of raised ribs arranged at approximately 45 degree intervals about the funnel interior surface.Type: GrantFiled: July 9, 1998Date of Patent: July 4, 2000Assignee: Empire Comfort Systems, Inc.Inventor: Donald P.
