  • Patent number: 3990586
    Abstract: An apparatus is described for applying leverlids to filled paint cans so that a later machine may fit the lids onto the cans by downward pressure. The apparatus has an inclined chute onto which the lids are fed and which is arranged to discharge the lids accurately onto paint cans moving on a horizontal conveyor beneath the apparatus. To control the movement of the lids onto the cans two release members rotatable about generally vertical axes are mounted on either side of the chute outlet so as to obstruct the outlet until such time as a paint can on the conveyor frees the release members for movement and thereafter pushes the release members aside.
