Abstract

This hub is for gripping a tape reel on a magnetic tape drive. The hub is easily operated to grip or release a reel by manually rotating cap 1 by less than 1200. Cap 1 is supported against hub 7 by stud 5 fastened centrally within cap 1, engaging fingers 6 which are molded integrally with the hub structure. Cap 1 is engaged or released by pulling or pushing stud 5 from or into fingers 6. Hub 7 is fastened to spindle shaft 8 of a tape drive and rotates with it. Cylindrical rubber sleeve 4 is slipped over the outer diameter of hub 7 and is held between shoulder 3 of hub 7 and shoulder 9 of cap 1.

Quick Release Hub

This hub is for gripping a tape reel on a magnetic tape drive. The hub is easily operated to grip or release a reel by manually rotating cap 1 by less than 1200. Cap 1 is supported against hub 7 by stud 5 fastened centrally within cap 1, engaging fingers 6 which are molded integrally with the hub structure. Cap 1 is engaged or released by pulling or pushing stud 5 from or into fingers 6. Hub 7 is fastened to spindle shaft 8 of a tape drive and rotates with it. Cylindrical rubber sleeve 4 is slipped over the outer diameter of hub 7 and is held between shoulder 3 of hub 7 and shoulder 9 of cap 1.

Cylindrical portion 11 of cap 1 is slipped within the cylindrical portion 12 of hub 7 when cap 1 engages hub 7. Portion 11 contains three cam indentations 10, equiangularly spaced about the outer periphery of cylinder 11. Indentations 10 are formed so that the outer surface of cylinder 11 spirals inwardly within indentations 10 until it ends at wall 13 bounding the end of an indentation 10. Three pads 14 are supported equiangularly. They are integrally formed as part of portion 12 as part of the same plastic coating. When cap 1 is engaged with hub 7, indentations 10 are aligned with pads 14 so that pads 14 will be slipped loosely within indentations 10.

In operation, the hub opening of a tape reel is slipped over sleeve 4 and against shoulder 3 of hub 7. Cap 1 is then manually turned approximately 900 in the direction of the arrow until resistance is felt...
