Abstract: The invention relates to a limited torque applicating mechanism for applying caps to the threaded necks of containers. Torque is transmitted to a conventional cap applicating head from a rotating power shaft by positioning a ring of permanent magnets on either the driven or driving element and disposing a ring of high magnetic permeability material concentrically adjacent on the other of the driven or driving elements so that the torque transmitted between the driving and driven elements is limited by the magnetic attraction between the ring of permanent magnets and the ring of high permeability magnetic material. The apparatus further incorporates a mechanism for adjusting the relative axial position of the ring of permanent magnets with respect to the ring of high magnetic permeability material to permit selective adjustment of the amount of torque transmitted.

Abstract: The invention provides an apparatus for effecting the orientation of shallow disc-shaped articles such as closures, lids and caps so that all such articles are moving at high speed in side by side relationship with each article having its recessed side in the same orientation as all other articles. Such orientation is accomplished by the employment of a single rotating wheel, the elastomeric peripheral surface of which projects through one wall of a feed chute through which the successive articles are moving at high speed in side by side relationship, and co-operates with an aperture in the opposite side wall of the chute to effect the selective direction of the successive articles into either one of two transfer chutes disposed in Y-shaped, tangential relationship to the end of the first mentioned chute according to whether the recessed face of the article is facing toward or away from the wheel periphery.
