Spring-Loaded Magnetic Disk Wipe

The disk wipe includes a strip of cloth 2 which is held in contact with hard magnetic disk 4 by spring loaded pads 6 and 8 for wiping contamination off of disk 4 as disk 4 is rotated about its center.

Cloth strip 2 extends around clamping roller 10, outer pad 12, inner pad 6, center post 14 of arm 15, inner pad 8, outer pad 16 and clamping roller 18. Pads 12 and 6 are fixed on dowel 20, and pads 8 and 16 are fixed on dowel 22. Dowels 20 and 22 are slidably disposed in opposite spaced arm portions 24 and 26 of arm 15, and springs 28 and 30 are disposed between the bottoms of recesses provided in arm portions 24 and 26 and pads 6 and 8. Rollers 10 and 18 are disposed on the ends of bowed springs 32 and 34 having their other ends fixed with respect to arm 15 by studs 36 and 38. Rollers 10 and 18 are held in tight engagement with the sides of V-shaped channels 40 and 42 carried by arm 15 due to the action of bowed springs 32 and 34 for holding the ends of cloth 2 fixed with respect to arm 15, with cloth 2 being thus held taut across pads 12, 6, 8 and 16.

Arm 15 is moved in direction 44 toward the center of disk 4 as disk 4 is rotating about its center so that the portions of cloth 2 supported by pads 6 and 8 wipe contamination off of disk 4. Springs 28 and 30 yield as pads 6 and 8 move onto disk 4, spaced therefrom only by the thickness of cloth 2, so as to hold cloth 2 in firm contact with disk 4. Pads 12 and 16 move...
