  • Patent number: 4177790
    Abstract: Three wire leg members are attached to a relatively small hub member and are movable between a folded position in which all three leg members are relatively together and an in use position in which the three leg members are substantially equally spaced apart and extend radially outwardly from the hub member. A gas burner unit is received within an upwardly directed recess formed in the hub member and includes an upwardly directed burner head. The wire leg members have lower portions restable on a support surface and upper portions providing a pan support at a level above the burner head. A flexible hose extends from the burner unit to a control valve and adaptor assembly attachable to the top of a can of butane gas. The control valve includes a knob and means controlled by rotation of the knob for moving a depressable member which is a part of an outlet valve built into the can, for both turning the gas flow on and off and regulating its flow rate.
