Patent number: 4813726Abstract: The invention relates to panels, such as are provided in cabinets or the like. Rabbets are provided in a frame for receiving a panel. Mortises are provided extending in the frame from the rabbets, and rotatable retaining element are mounted in the mortises. The rotatable retainers are comprised of a ramp encircling them for a proton of their circumference, having one flat circumferential side that is alignable with the side of the rabbet in the frame. Accordingly, upon rotation of the retainer, the ramp, or screw thread, engages the side of the panel away from the bottom of the rabbet, to hold the panel fully against the bottom of the rabbet, independently of the thickness of the panel.Type: GrantFiled: January 19, 1988Date of Patent: March 21, 1989Assignee: The Tappan CompanyInventor: Ernest Ravinet

Patent number: 4568810Abstract: A microwave oven with a microprocessor control which contains stored recipe information. The user enters food type, quantity to be cooked, and size or doneness desired. Data for cooking a large number of different foods may be stored. The specific food item to be cooked is user selected by touching and holding one of ten food category pads. Food items within the category selected then "scroll" through an alphanumeric display. The item shown in the display when the food pad is released is the one selected for cooking. Following food selection, the user is prompted, via the alphanumeric display, to enter such additional data as quantity, size and doneness desired.Type: GrantFiled: January 17, 1984Date of Patent: February 4, 1986Assignee: The Tappan CompanyInventor: Silas E. Carmean

Patent number: 4499630Abstract: An adjustable knob assembly for operating a gas valve includes a rotatable knob affixable to the shaft of the gas valve and having a hub with an axially extending ridge. An annular pointer is angularly displaceably affixed to the hub and has opposed sets of adjacent grooves selectively alignable to engage the ridge on the hub, to permit angular displacement of the pointer with respect to the shaft.Type: GrantFiled: September 27, 1982Date of Patent: February 19, 1985Assignee: The Tappan CompanyInventors: Stephen K. Harris, Wiley W. Miller

Patent number: 4310933Abstract: A disposer mount assembly includes a non-rotatable plastic sink flange having a tubular portion extending downwardly through and beneath the drain opening and terminating in a lip resiliently embraced by an elastomeric cushion mount, a mounting ring with inclined camming slots rotatably mounted on the tubular portion by the cushion mount, and a disposer hopper having an upper flange with lugs projecting radially outwardly therefrom into the camming slots. Selective rotation of the mounting ring cams the lugs upwardly along the inclined camming slots to a final locked position therein in which the correspondingly elevated hopper flange is connected to the mount ring and compresses the cushion mount, thereby to provide a tight resilient seal between the disposer and sink flange to absorb vibration and sound.Type: GrantFiled: July 6, 1979Date of Patent: January 19, 1982Assignee: Tappan CompanyInventor: Jerome F.
