APPARATUS FOR SCREWING CAPS ON CONTAINERS Abstract of the Disclosure A housing that is continuously rotatable on a verti- cal axis has an opening in its bottom and contains a central vertical shaft rotatable a limited number of degrees relative to the housing. This shaft is connected through the housing opening with a chuck that contains means for gripping a screw cap to screw it onto a container. Valve means connect a source of air pressure with the gripping means to cause such means to grip a screw cap. Secured to the housing is a valve member pro- vided with a bleed passage through it, the inlet of which is connected with the air pressure source and the outlet of which normally is closed by a closure member. Projecting from the side of the shaft is a torque arm that is pressed by compressible means carried by the housing to cause stop means projecting from the side of the shaft to move the closure member away from the bleed passage a certain distance. When the torque applied by the gripping means to the screw cap becomes sufficient to com- press said compressible means so that the chuck substantially stops rotating, the valve means is shifted by air pressure re- sponsive means to release air pressure from the gripping means. The pressure responsive means is connected with the air source and the bleed passage inlet for actuating the pressure responsive means when the valve member moves away from the stop means as the screw cap substantially stops rotation of the torque arm. The apparatus includes a flexible connection that permits appli- cation of screw caps to containers that are eccentric to the axis of rotation of the housing.
