Abstract

Cloth strip 1 is held in undulated disposition over spaced fingers 2 and dowels 3 between fingers 2 all carried by swing arm 4 so that cloth 1 may embrace spaced magnetic disks 5 of disk pack 6 as swing arm 4 is swung to wipe disks 5 clean. (Image Omitted) Fingers 2 and dowels 3 are in a finger assembly 7 that is fixed on the end of arm 4 which is swingably mounted by means of pivot 8. Cloth 1 is held taut over fingers 2 and dowels 3 by means of clamps 9 and 10. Each of the clamps 9 and 10 comprises a roller 11 entering a V-shaped recess 12 carried by assembly 7 and held in the recess 11 by means of a bowed leaf spring 13 fixed at one end to assembly 7 by means of a stud 14. Cam 15, fixed on rotatable shaft 16, functions to raise and lower swing arm 4 as cam 15 and shaft 16 are rotated.

Wipe Mechanism for Disk Pack Assemblies

Cloth strip 1 is held in undulated disposition over spaced fingers 2 and dowels 3 between fingers 2 all carried by swing arm 4 so that cloth 1 may embrace spaced magnetic disks 5 of disk pack 6 as swing arm 4 is swung to wipe disks 5 clean.

(Image Omitted)

Fingers 2 and dowels 3 are in a finger assembly 7 that is fixed on the end of arm 4 which is swingably mounted by means of pivot 8. Cloth 1 is held taut over fingers 2 and dowels 3 by means of clamps 9 and 10. Each of the clamps 9 and 10 comprises a roller 11 entering a V-shaped recess 12 carried by assembly 7 and held in the recess 11 by means of a bowed leaf spring 13 fixed at one end to assembly 7 by means of a stud 14. Cam 15, fixed on rotatable shaft 16, functions to raise and lower swing arm 4 as cam 15 and shaft 16 are rotated. Shaft 16 is driven by motor 17, and photoswitch 18 cooperating with hole 19 functions to deenergize motor 17 when arm 4 has completed one cycle of movement. When motor 17 is energized, cam 15 rotates and causes arm 4 to swing downwardly about pivot 8 and thereby causes cloth strip 1, supported by fingers 2, to brush across disks 5 which are kept in continuous rotation about their centers at this time. Cam 15 allows fingers 2 to move to the ID of disks 5 and then on continued rotation moves arm 4 back to the original position in which hole 19 cooperating with photoswitch 18 deenergized motor 17.
