摘要： A two piece portable toilet is described. The toilet includes a bowl unit which defines a toilet bowl having a discharge opening, and a reservoir for a flushing liquid, said reservoir having a normally closed filler opening. A holding tank is normally disposed below and supports the bowl unit. The holding tank has a top wall and defines a waste holding chamber having an inlet opening in said top wall for communication with the discharge opening of the toilet bowl. The chamber also has a normally closed outlet opening. The top wall of the tank is contoured to define a depression around the holding chamber inlet opening and, on opposite sides of the depression, surfaces for supporting said bowl unit. Coupling means normally maintain the bowl unit and holding tank in co-operating relationship when the toilet is in use. The coupling means allow the unit and tank to be separated at appropriate times. The toilet also includes pump means communicating with the reservoir in the bowl unit and with the toilet bowl and operable in use to deliver flushing liquid from the reservoir into the bowl. Valve means are also provided for controlling discharge of material from the toilet bowl into the holding chamber. The valve means are disposed in the depression in the top wall of the holding tank and includes a flap-form closure member which is pivotable about an axis generally normal to the axis of the discharge opening of the toilet bowl. The closure member is movable between a position in which the member prevents communication between the discharge opening of the bowl and the waste holding chamber, and a position in which the closure member has pivoted downwardly clear of the opening to allow discharge of material from the toilet bowl into said chamber. A valve operating means is normally disposed below and supports the closure member in its closed position and is retractable to allow the closure member to pivot downwardly about its said axis and allow communication between the discharge opening of the bowl and the inlet of the waste holding chamber.

摘要： A cable controller is formed by a housing having a cavity into which one end of a handle is received and mounted for a pivotal movement on a pivot pin extending across the housing. The pivot pin is received within a L-shaped slot adjacent to one end and the top of the handle and an abutment is provided projecting outwardly from the bottom of the handle in position to engage the rim of the cavity. A control cable is connected to the handle positioned about midway between the abutment and the slot. The slot and the abutment are positioned so that movement of the handle in a first direction pivots the handle about the pivot pin and extends the cable and movement of the handle in the opposite direction pivots the handle about the point of contact between the abutment and the rim of housing to move the pin along the slot into a short section of the L-shaped slot to thereby extend the cable now lock the handle in a parking position.
