  • Patent number: 5564343
    Abstract: An adjustable shelf for a paint colorant dispensing station comprises at least two platforms rotatably mounted on a pair of brackets. A pair of stops restrain the rotation of the shelf between two positions. One of the platforms is substantially horizontal and disposed beneath a dispensing head in one of the positions. The other platform is substantially horizontal and disposed beneath the dispensing head in the other of the positions. Each platform is adapted to hold a paint can. Each stop is adjustable by rotating the stop relative to the shelf. The rotation causes a threaded rod to extend from or retract to the element that supports the stop. A locking mechanism is provided to selectively restrain the shelf against rotation when the shelf is in one of the two positions.
