Abstract
An apparatus for abrading a surface is provided. The apparatus has a compact profile and includes a drive mechanism disposed in a housing. The drive mechanism includes a substantially vertical drive shaft rotatably mounted on a first plate and including a drive pulley mounted on the shaft. The drive pulley is rotatably connected to at least one coplanar pulley mounted on a substantially vertical shaft and disposed between the first plate and a second plate attached substantially parallel to the first plate. Thus, use of the apparatus in height-restricted spaces is facilitated.
Claims8
An apparatus for abrading a surface, the apparatus having a motor and further comprising:
- (a) a primary pulley connected to and adapted to be driven by the motor;
- (b) a single drive component in contact with said primary pulley;
- and
- (c) a plurality of secondary pulleys, each pulley of said primary and secondary pulleys being adapted to rotate a corresponding disk, said corresponding disk being adapted to receive an abrasive pad,
- wherein said each pulley and said corresponding disk are mounted on a corresponding substantially vertical shaft rotatably mounted at opposing ends thereof on a first plate and a second plate attached substantially parallel to said first plate, respectively, such that said each pulley is disposed between said first and second plates;
- wherein said drive component is in continuous serpentine contact with each said pulley of said primary and secondary pulleys such that each said corresponding disk rotates when said primary pulley is driven;
- and
- wherein a primary shaft corresponding to said primary pulley extends above said second plate to form an extended end, said primary pulley being mounted on said primary shaft such that said primary pulley is driven when said extended end is driven.
