Abstract
An assembly for engaging the central bore of a narrow, standing heavyweight reel element, or the core thereof adjacent the opening of the bore, to facilitate the manual lifting and locking of such reel to an elevated shaft-alignment position for transfer of such reel onto a receptive horizontal shaft. The assembly comprises an elevated support member, a lever arm pivotally-attached thereto for vertical movement and including engagement means for locking the lever arm in raised position. The lever arm also has pivotally-attached thereto a depending swivel arm having a substantially-horizontal hub member for engaging the bore or core of the reel, supporting the reel in vertical position as the lever arm is raised and locked in shaft-alignment position and permitting the reel to be pushed onto the receptive shaft.
Claims8
An assembly, designed for use in association with an apparatus having an elevated horizontal receiving shaft, for facilitating the lifting, alignment and transfer of a heavyweight narrow reel having a shaft-engaging bore onto said shaft, said assembly comprising a pivot support means designed to be mounted in vertical alignment above the receiving shaft by a distance greater than the radius of the reel to be mounted thereon, an elongate lever arm having an attachment end, a handle end and an intermediate depending pivotally-attached swivel extension arm terminating in a hub support means, means for pivotally attaching the attachment end of said lever arm to said pivot support means in vertical alignment above the receiving shaft of an apparatus so that said swivel extension arm depends from said lever arm and said hub support means extends from said swivel extension arm in a horizontal direction towards said receiving shaft, manual lifting of the handle end of said lever arm causing said lever arm to pivot on said pivot support means and raise said swivel extension arm and its hub support means between horizontal lower position, in which the hub support means can be engaged adjacent the bore of a heavyweight narrow reel, and horizontal raised position in which the bore is in alignment with the receiving shaft, to permit manual transfer of the reel onto the receiving shaft, and means for locking said lever arm in raised position.
