  • Patent number: 4270669
    Abstract: An apparatus is disclosed for separating and dispensing nursery pots which are nested in a stack. The apparatus includes a ratchet mechanism which allows the stack to move in only one direction along a predetermined path, an elongated bar mechanism for engaging the first pot at one end of the stack and pulling it away from the pots in the stack and a contact off switch which responds to the presence of a pot at a dispensing location along said path to deactivate the bar mechanism until such time as the pot is removed by the operator.
