Abstract
Abstract Apparatus for handling large rolls of paper or spools of wire including a pair of outwardly extending arms, supported by air bearings, which straddle the roll or reel along the axis in a lower hemisphere. The roll is lifted upon inflation of the bearing and transported to its desired location. The parallel arms are adjustable toward and away from each other to accommodate rolls of varying diameters and may include stabilizing members for use with a reel in the event the arms are not of a sufficient length to extend beneath both flanges.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
153 words
A device supported by air bearings, for transporting rolls of paper or the like, said device comprising: a pair of opposing platform means designed to support a roll without damage thereto, movable relative to each other and having secured to each of their bottom surfaces at least one air bearing, rigid means at one end of the platform means interconnecting and defining the relative movement of the platform means which are slidably mounted thereon, means supplying air under pressure to the bearings, and control means whereby the device may be placed adjacent the roll to be transported with the platform means extending in the direction of the axis of the roll along either side thereof and beneath the roll at a distance from each other which is less than the outer diameter of the roll whereby the roll will be lifted upon inflation of the bearings and thus transported to the desired location.
Claim 2
Independent Claim
153 words

Claim 3
Dependent Claim
23 words
A device as in claim 1, wherein the platform means include roll contacting elements mounted upon the upper surface of the platform means.
Claim 4
Dependent Claim
13 words
A device as in claim 2, wherein the roll contacting elements are parallel.
Claim 5
Dependent Claim
17 words
A device as in claim 1, and further including handle means enabling easy movement by the operator.
Claim 6
Dependent Claim
23 words
A device as in claim 2, wherein an upstanding roll support is located adjacent the interconnecting means to contact and support the roll.
Claim 7
Independent Claim
77 words
A device for handling rolls of paper or the like comprising: a pair of substantially parallel arms slideably secured to an interconnecting member generally perpendicular to the pair of arms, whereby the arms may be moved to accommodate various sized rolls, platform means secured to and supporting each of the arms and having mounted to the bottom surface thereof fluid bearing means and means providing fluid under pressure to the bearings enabling an easy lift and transport.
