Abstract
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.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
237 words
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.
Claim 2
Dependent Claim
237 words
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.
Claim 3
Dependent Claim
48 words
An assembly according to claim 1 in which said pivot support means comprises an extension arm, one end of which is attached for horizontal extension in vertical alignment above the receiving shaft, said extension arm having, adjacent the other end thereof, pivotal attachment means for the lever arm.
Claim 4
Dependent Claim
29 words
An assembly according to claim 2 in which said extension arm carries, adjacent said other end, a means for engaging the lever arm to lock it in raised position.
Claim 5
Dependent Claim
134 words
An assembly according to claim 3 in which said extension arm is a vertical flat plate having, adjacent said other end thereof, a transverse upward slot and supporting thereabove a pivotable latch means having a transverse downward slot, and the attachment end of said lever arm comprises a vertical slot containing spaced transverse outer and inner pins, the lever arm being attachable to the flat plate by inserting the plate within the said vertical slot and engaging the said outer pin within the said upward slot to provide pivotal attachment therebetween, the lever arm being lockable in raised position by pivoting it upward to cause the latch means to pivot open until the said inner pin of the lever arm engages the said downward slot of the latch means to provide a locking means.
Claim 6
Dependent Claim
45 words
An assembly according to claim 1 in which the depending swivel extension arm of the lever arm is shaped so that its point of pivotal attachment to the lever arm maintains a reel engaged by the hub support substantially vertical at all times during use.
Claim 7
Dependent Claim
24 words
An assembly according to claim 1 in which said hub support means comprises a projecting hub means which is receivable within the shaft-engaging bore.
Claim 8
Dependent Claim
67 words
An assembly according to claim 2 in which said assembly comprises a support frame, said extension arm is pivotally attached to the support frame, and the lever arm is removably attached to said extension arm so that the lever arm can be removed from the extension arm and the extension arm can be pivoted back over the support frame and out of position during periods of nonuse.
Claim 9
Dependent Claim
29 words
An assembly according to claim 2 in which said support frame comprises means for adjusting the height of the horizontal extension of said extension arm above said receiving shaft.
