Abstract
Abstract A conveyor roll arrangement provides for a hollow roll body that is journalled for rotation about a roll axle that is supported by two elongated supports; and clamping means are provided for supporting each roll axle end on a support and has two normally substantially parallel, normally substantially equidistant elongated plates with aligned apertures which receive the roll axle end, and adjusting means which can vary the distance between the plates near one end relative to the distance near the other end of said plates, so as to clamp effectively and in exact predetermined position the roll axle ends.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
139 words
A conveyor roll arrangement, for use in connection with two elongated supports, comprising in combination, a roll axle being adapted to be supported immovably from said supports with the axis of the roll axle disposed substantially perpendicular to the direction of elongation of said supports, a hollow substantially cylindrical roll body journalled for rotation about said roll axle and having rims mounted near the opposite roll body ends, and clamping means adapted for supporting each roll axle end on a support, comprising two normally substantially parallel, normally substantially equidistant elongated plates defining substantially aligned apertures receiving said roll axle end, and adjusting means operable to vary the distance between said plates near one end relative to the distance near the other end of said plates, whereby said roll axle ends will be clamped effectively and in exact predetermined position.
Claim 2
Dependent Claim
139 words
A conveyor roll arrangement, for use in connection with two elongated supports, comprising in combination, a roll axle being adapted to be supported immovably from said supports with the axis of the roll axle disposed substantially perpendicular to the direction of elongation of said supports, a hollow substantially cylindrical roll body journalled for rotation about said roll axle and having rims mounted near the opposite roll body ends, and clamping means adapted for supporting each roll axle end on a support, comprising two normally substantially parallel, normally substantially equidistant elongated plates defining substantially aligned apertures receiving said roll axle end, and adjusting means operable to vary the distance between said plates near one end relative to the distance near the other end of said plates, whereby said roll axle ends will be clamped effectively and in exact predetermined position.
