Patent number: 8404292Abstract: A food warming apparatus includes a heating compartment that can hold one or more trays containing previously cooked food portions. A cover for a tray has a horizontal section and a vertical section extending downwardly from one side of the horizontal section. A rack in the heating compartment includes a channel and a stop that blocks the front end of the channel. The vertical section of the cover fits securely in the channel behind the stop such that the rack supports the cover substantially only through the vertical section. When a tray is inserted into the receiving space cooperatively defined by the cover and rack, the cover is lifted up so that the horizontal section rests on the tray and at least partially blocks the open top of the tray, thereby restricting evaporation of liquids from the previously cooked food portions contained in the tray.Type: GrantFiled: December 14, 2011Date of Patent: March 26, 2013Assignee: Prince Castle, Inc.Inventors: Loren J.

Patent number: 7971523Abstract: A food warming apparatus includes a cabinet with one or more heating compartments for holding one or more trays. Each tray has a rim extending outwardly from a tray opening and may contain previously cooked food portions. One or more dividers are removably mounted inside a heating compartment, dividing the heating compartment into a first sub-compartment and second sub-compartment. The one or more dividers include a first support flange that extends into the first sub-compartment and a second support flange that extends into the second sub-compartment. The first support flange supports a rim of a first tray in the first sub-compartment such that the first tray is suspended above a lower compartment surface of the heating compartment. The second support flange supports a rim of a second tray in the second sub-compartment such that the second tray is suspended above the lower compartment surface of the heating compartment.Type: GrantFiled: November 15, 2007Date of Patent: July 5, 2011Assignee: Prince Castle, Inc.Inventors: Charles Hartfelder, Loren J.

Patent number: 7858906Abstract: A food warming apparatus includes a heating compartment that can hold one or more trays containing previously cooked food portions. A rack in the heating compartment includes a support member, a channel, and a stop that blocks the front end of the channel. A cover that includes a horizontal section and a vertical section is mounted on the support such that the horizontal section is supported on one side by the support member and on the other side by the vertical section, which is positioned in the channel behind the stop. When a tray is inserted into the receiving space defined by the cover and support member, the cover is lifted up so that the horizontal section rests on the tray and at least partially blocks the open top of the tray, thereby restricting evaporation of liquids from the previously cooked food portions contained in the tray.Type: GrantFiled: June 8, 2007Date of Patent: December 28, 2010Assignee: Prince Castle, Inc.Inventors: Loren J.
