  • Patent number: 5953962
    Abstract: 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.

  • Patent number: 4091475
    Abstract: 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.
