  • Patent number: 4266717
    Abstract: The assembly is utilized in a centrifuge device wherein a receptacle is received and held between first and second platens which are held within a platen holder fixed to the centrifuge device and in respective inner and outer parallel planes spaced radially outwardly from a vertical axis of rotation of the centrifuge device. The first platen is movable with one side wall of the holder about a generally horizontal axis extending along a lower edge of a second side wall of the holder. A latch mechanism provides for a toggle latching action between the walls as the latch mechanism is moved from an open position to a closed position. In one embodiment of the latch mechanism a handle is connected to a shaft journalled on the one side wall and mounts a plate on each end thereof with each plate having a pin extending therefrom that is rotated within a keeper member on an edge of the second wall to latch the platens in place.
