Abstract

Abstract A cable reel comprises a pair of annular flanges and a hollow cylindrical core extending between the flanges. Each end portion of the core is engaged in an annular groove formed on the inner surface of each flange. A tubular element is located within the core to act as a guide for a supporting spindle, the end portions of the element being engaged in stepped portions of the flanges. The flanges are reinforced by radial ribs and are retained against the core by means of at least three tie rods.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 233 words
A reel for very thin cables, such as telephonic cables, comprising, a hollow cylindrical core, two disc-shaped flanges made of a molded plastic material, each flange having a central aperture arranged to permit passage of a supporting spindle, and each flange being provided on its inner surface with an annular groove molded thereinto so as to have a radial size equal to the thickness of said core, the opposite annular end portions of said cylindrical core being removably received in the respective annular groove of the correspondng flange substantially without play and being supported therein radially inwardly and outwardly, a plurality of radial reinforcing ribs provided on the outer surface of each flange, each said rib extending radially outwardly from a position adjacent to but radially outwardly from the annular groove to a position adjacent the peripheral edge of the flange, the cross-sectional area of each said rib decreasing with increasing distance from the center of the flange, a stepped portion formed on the inner surface of each flange which is adjacent the central aperture, an inner tubular element arranged to act as a guide for the supporting spindle, the respective end portions of the tubular element being engaged with the stepped portion of each flange, and a plurality of tie rod means and nut connections arranged between the two flanges inwardly of said cylindrical core to urge the flanges toward one another.
Claim 2
Dependent Claim 233 words
A reel for very thin cables, such as telephonic cables, comprising, a hollow cylindrical core, two disc-shaped flanges made of a molded plastic material, each flange having a central aperture arranged to permit passage of a supporting spindle, and each flange being provided on its inner surface with an annular groove molded thereinto so as to have a radial size equal to the thickness of said core, the opposite annular end portions of said cylindrical core being removably received in the respective annular groove of the correspondng flange substantially without play and being supported therein radially inwardly and outwardly, a plurality of radial reinforcing ribs provided on the outer surface of each flange, each said rib extending radially outwardly from a position adjacent to but radially outwardly from the annular groove to a position adjacent the peripheral edge of the flange, the cross-sectional area of each said rib decreasing with increasing distance from the center of the flange, a stepped portion formed on the inner surface of each flange which is adjacent the central aperture, an inner tubular element arranged to act as a guide for the supporting spindle, the respective end portions of the tubular element being engaged with the stepped portion of each flange, and a plurality of tie rod means and nut connections arranged between the two flanges inwardly of said cylindrical core to urge the flanges toward one another.
Claim 3
Dependent Claim 44 words
A reel according to claim 1 wherein each said flange further comprises, a projection in each said annular groove, each end portion of the core having a notch which cooperates with the projection whereby to prevent rotation of the flanges relative to the core.
Claim 4
Dependent Claim 36 words
A reel according to claim 1, wherein each said flange has a recess in its outer surface arranged to receive a respective said nut means, whereby the nut means lie within the thickness of the flange.
Claim 5
Dependent Claim 15 words
A reel according to claim 1, wherein each flange further comprises a peripheral reinforcing rim.
Claim 6
Dependent Claim 26 words
A reel according to claim 1, wherein at least one flange has an elongate recess arranged to cooperate with a finger rigid with the supporting spindle.
Claim 7
Dependent Claim 36 words
A reel according to claim 5, wherein the recess is located within a reinforced portion of the flange whereby to provide a greater area of contact for the finger on the inner surface of the recess.
Claim 8
Dependent Claim 17 words
A reel according to claim 6, wherein the recess is located adjacent the center of the flange.
