Abstract
Abstract A dumping apparatus for lifting a refuse cart so as to cause the contents to fall from the cart. The dumping apparatus has two claw-like hands mounted to arms which are fixedly fastened to a shaft rotatably mounted in two vertical members. A sprocket attached to the end of the shaft is driven causing the two hands to automatically engage and lift cylindrical rods fastened to either side of the refuse cart. Projections are fastened to the forward wall of the cart and engage the cylindrical shaft causing the cart to rotate as it is being lifted. A bumper bar is fastened to the two vertical members forcing the two rods fastened to the cart wall to disengage from the inner cylindrical portion of the claw-like hands as the cart is placed back in a horizontal position.
