ABSTRACT:
Apparatus for applying container caps of different sizes to containers includes a main housing arranged for rotation by a driving spindle, an upwardly biased cam rod coaxially disposed relative to the spindle and movable reciprocably, a releasable holding device normally restraining the cam rod against upward movement, a transverse cam follower shaft mounted in a transverse passage formed in the cam rod and having outwardly projecting ends, on which a pair of cam followers are rotatable, a main cam fixed in position relative to the main housing and disposed about the cam rod and having opposed vertical cam tracks in which the outwardly projecting cam followers are disposed, a helix cam arranged for limited angular movement and disposed about the cam rod and within the main cam and having opposed helical cam tracks in which the outwardly projecting ends of the transverse cam followers are disposed whereby limited angular movement is imparted to the helix cam by the biasing means upon release of the cam rod by the releasable holding device, gripping mechanism supported by the housing for lightly gripping a container cap in coordination with limited angular movement of the helix cam and an adjustable worm arranged to change the angular position of the main cam relative to the main housing thereby to adapt the apparatus for use in conjunction with container caps of different diameters.
