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.

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 pulleys comprising said primary pulley, each pulley of said plurality of pulleys being adapted to rotate a corresponding disk, said corresponding disk being adapted to receive an abrasive pad,
- whereby said drive component is in continuous serpentine contact with said plurality of pulleys such that each said corresponding disk rotates when said primary pulley is driven.
An apparatus for abrading a surface, the apparatus comprising:
- (a) receiving means for receiving an abrasive pad;
- (b) rotating means for rotating said receiving means;
- and
- (c) driving means for driving said rotating means while in continuous serpentine contact with a plurality of said rotating means such that a plurality of said receiving means are rotated when said rotating means is rotatably driven.
An apparatus for abrading a surface, the apparatus having a compact profile and comprising a drive mechanism disposed in a housing, said drive mechanism comprising a substantially vertical drive shaft rotatably mounted on a first plate and including a disk and a drive pulley mounted on said shaft, said disk being operable to receive an abrasive pad, said drive pulley being rotatably connected to at least one coplanar pulley mounted on a substantially vertical shaft and disposed between said first plate and a second plate attached substantially parallel to said first plate, thereby facilitating use of the apparatus in height-restricted spaces.
