Abstract
A lift mechanism lifts a bottle of water from a lower upright position to an elevated position at which it can be lowered into a well of a water cooler. The lift mechanism includes a bottle elevator and cam operated bottle turning assembly. A closure on the bottle is adapted to be activated by surfaces of the cooler well to move a plunger from a closed position to a position at which water is adapted to flow out of the bottle.
Claims18
A lifting mechanism for lifting a bottle containing a liquid from a lower upright position to an elevated inverted position comprising:
- a frame including a base;
- a motor supported on the base;
- a threaded screw rotatably journalled on the frame and driven by the motor;
- a vertically extending elevator rail supported on the frame;
- a bracket movable on the frame;
- a nut on the bracket meshing with the threaded screw so that rotation of the screw will move the bracket in a vertical direction;
- a sleeve supported on the bracket;
- a rotatable rod rotatably supported within the sleeve;
- bottle support means at one end of the rod for embracing and supporting the bottle;
- cam means for cooperating in turning the bottle at the other end of the rod;
- and
- bearings supported on the frame for engaging the cam means as the bracket is moved vertically to cause the rod to rotate and consequently cause the bottle to turn from its lower upright position to its elevated inverted position.
