  • Patent number: 4792236
    Abstract: A paint tinter system includes a plurality of canisters disposed in a circle about a rotatable plate. An orbiting plate, driven by a single motor, is connected to drive arms, each of which is connected to a crank arm of a stirrer in one of the canisters. The connection is made through a lost-motion device in a cap covering each canister. The cap captures the end of the drive arm, whereby the cap may be removed and hinged out of the way for providing access to the canister. An impeller is freely mounted for rotation in a socket in the bottom of the canister. The upper end of the impeller is driven by engagement between a pair of driver bosses rotated by the crank and edges of a top plate on the canister. Thus, when the cover is removed, the impeller may remain unmoved or be lifted from the socket for cleaning.
