Abstract: Apparatus for handling magnetizable sheet material, and especially heavy metal plates, which apparatus comprises an overhead conveyor characterized by a supporting frame structure on which a plurality of magnetic roll or roller assemblies are mounted which roller assemblies include a magnet structure with a core having end extensions on which are rotatably carried sheet contacting and supporting rollers with associated pole extension members which are spaced along and extend radially of the axis of the core and which present a downwardly facing bottom surface area of substantial length extending fore and aft of the rollers and in spaced, confronting relation above the top surface of the material contacting the rollers so as to provide a wide flux path which is effective to draw the material into contact with the rollers, the pole extension members having non-magnetic wing portions enabling the connecting of successive roll assemblies being supported for limited vertical movement so as to afford sufficient fle

Abstract: A rail-type conveyor unit is disclosed for handling metal sheets or similar articles which is characterized by an elongate frame having sprocket assemblies at opposite ends on which are supported a pair of parallel, roller-type, endless chains, and having a series of electromagnets mounted in longitudinally spaced relation thereon which are operative for holding the sheets against padded cross members connecting the chains as the latter traverse a path along the bottom of the conveyor, the cross members being mounted on chain link pivot pins and the chain rollers riding on transversely spaced, track-forming rail members which constitute a part of depending extensions of the electromagnet pole members, and the electromagnet assemblies and associated rail members being arranged in the form of separate, longitudinally spaced units with connecting members of non-magnetic material.

Abstract: A wire spring attachment for mounting on the temples of eyeglass frames so as to exert a pull on the temples when the eyeglasses are in use with sufficient pressure against the back of the head or upper neck portion of the wearer to prevent movement of the eyeglasses out of proper position, especially, when the wearer moves his head out of normal upright position in leaning over or the like.This invention relates to eyeglass constructions and is more particularly concerned with improvements in attachments for eyeglass frame structures which are adapted to hold the eyeglass in proper position on the head of the wearer.
