The oven further includes a frame coupled to and at least partially surrounding the oven chamber. The oven further includes a door operable to seal the front opening of the oven chamber, and a pair of hinges pivotally coupling the door to the frame. Each hinge is positioned on opposing sides of the oven chamber. The oven further includes a pair counterweights that are each coupled to the rear portion of a respective hinge, and a pair of dampers. Each damper is coupled to the frame and operable to resist movement of the door in a single direction opposite that of the other damper.

Abstract: A door for a towel dispensing cabinet may be pivotable over an opening of a cavity. Frameworks may extend from a face of the door and define slots for stably receiving ends of a spindle assembly onto which a towel roll may be mounted. The frameworks may also include channels through which a shaft connecting the ends of the spindle assembly may be received to allow the spindle assembly to be received deeper into the slots. Towels may be dispensed from spindle assembly when stably received within the frameworks when the door is open. The door may be closed to position the spindle assembly within the cavity and seal the opening. The spindle assembly may also be removed from the frameworks for separate use when the door is open.

Abstract: An oven system may include a cooking chamber, a combustion chamber, and a flue. The flue may be arranged to route a first portion of the combustion gas produced in the combustion chamber into the cooking chamber and route a second portion of the combustion gas along a route that bypasses the cooking chamber. The flue may also be arranged to collect the first portion of the combustion gas from the cooking chamber and to exhaust both the first portion and the second portion of the combustion gas from the oven system.

Abstract: Disclosed is a convection oven capable of producing a “true” convection cooking environment with a single gas burner disposed underneath the oven bottom in a combustion box. A fan compartment is disposed substantially at the center of the back wall, and defined by a baffle plate with a central fan inlet, a plurality of rearward-extending flanges, and a portion of the oven back wall. A centrifugal fan is disposed within the fan compartment. A flue spout is disposed between the oven cavity and the fan compartment and is adapted to join the combustion box and the oven cavity in fluid communication. Thus the centrifugal fan, located substantially centrally within the fan compartment will draw hot air and flue products upward from the combustion box, through the flue spout, through the central fan inlet, and blow the hot air and flue products into the oven cavity through peripheral fan outlets formed in the fan compartment.

Abstract: Five burners are arranged in the form of an “x.” The units are covered by a grate including two side sections, each covering two burners, and a central section covering the center burner. The side sections have concave inner side edges that mate with a circular segment of the center grate.
