Abstract
Abstract A portable cable reel drive device which is removeably and adjustably attachable to large reels of varying widths and diameters having heavy metal cable or the like. The device includes a portable drive shaft having an adjustable reel hub engaging means, a hanger assembly for mounting and coupling the device to the reel itself, a shaft supporting device for supporting the shaft above ground and a tie down means for connecting and holding the shaft in place when it is being driven. The device is driven by a conventional, portable electric motor which is attachable to one end of the reel drive shaft. The device is especially useful for paying out heavy electrical cable on large reels to reduce the number of men required during the operation.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
193 words
A portable cable reel drive for rotating a cable reel having a hub and mounted on an axle and an axle support comprising: a drive shaft; at least one reel drive hub connected to said drive shaft; a drive shaft hanger assembly rotatably coupled to said drive shaft at one end and coupleable to said cable reel axle; said drive shaft hanger assembly mounting said drive shaft in proximity to said reel hub for engaging said reel drive hub with said reel hub; a detachable drive shaft stabilizing means for securing said drive shaft in a fixed position relative to said reel and said stabilizing means connected to said drive shaft and said axle support; and means connected to said drive shaft for coupling said drive shaft to a mechanical rotational energy source; said drive shaft hanger assembly includes a first flexible connector, having an axle coupling means disposed at one end and a drive shaft coupling means disposed at the opposite end, said drive shaft coupling means being rotatably coupled to said drive shaft to permit rotation of said drive shaft and means for adjusting the length of said first flexible connector.
Claim 2
Dependent Claim
193 words
A portable cable reel drive for rotating a cable reel having a hub and mounted on an axle and an axle support comprising: a drive shaft; at least one reel drive hub connected to said drive shaft; a drive shaft hanger assembly rotatably coupled to said drive shaft at one end and coupleable to said cable reel axle; said drive shaft hanger assembly mounting said drive shaft in proximity to said reel hub for engaging said reel drive hub with said reel hub; a detachable drive shaft stabilizing means for securing said drive shaft in a fixed position relative to said reel and said stabilizing means connected to said drive shaft and said axle support; and means connected to said drive shaft for coupling said drive shaft to a mechanical rotational energy source; said drive shaft hanger assembly includes a first flexible connector, having an axle coupling means disposed at one end and a drive shaft coupling means disposed at the opposite end, said drive shaft coupling means being rotatably coupled to said drive shaft to permit rotation of said drive shaft and means for adjusting the length of said first flexible connector.
Claim 3
Dependent Claim
46 words
A portable cable reel drive as in claim 1, wherein: said drive shaft stabilizing means includes a base support, said base support being connected to said drive shaft coupling means, and a second flexible connector coupled between said cable reel axle support and said base support.
Claim 4
Dependent Claim
45 words
A portable cable reel drive as in claim 2, wherein: said reel drive hub is mounted on said drive shaft and lockably movable along the longitudinal axial direction of said drive shaft so that said reel drive hub may be positioned along said drive shaft.
