Abstract
A cleaning tool scraps away undesirable slag which has accumulated on opposite sides of the slat of a worktable. The cleaning tool has a pair of cleaning assemblies each comprising a scraping tool. The scraping tools are positioned on opposite sides of a slat for simultaneously cleaning of the two sides of the slat. A single motor rotates both of the scraping tools. A biasing member retains the two scraping tools in close proximity to the slat as it is claimed.
Claims10
A cleaning apparatus for simultaneously cleaning opposing sides and teeth of rails of a support structure, comprising:
- a. a primary frame;
- b. first and second cleaning assemblies, each of said first and second cleaning assemblies comprising a secondary frame coupled to the primary frame, a gear train comprising a drive gear and a follower gear, a tool shaft having a first end coupled to the follower gear and a second end coupled to a scraping tool comprising a plurality of scraping blades, wherein the scraping heads of the first and second cleaning assemblies are adapted to reside in cleaning positions adjacent opposing sides of a rail to be cleaned;
- and
- c. a rotatable drive shaft having a first end coupled to the drive gear of the first cleaning assembly and a second end adapted to be coupled to and be rotated by a motor, wherein rotation of the drive shaft causes the gears of the gear train, the blade shaft and the scraping tool of both the first and second cleaning assemblies to rotate.
The apparatus of claim I wherein the secondary frames of the first and second cleaning assemblies are pivotally coupled to the primary frame.
The apparatus of claim 9 further including at least one biasing member having a first end coupled to the secondary frame of the first cleaning assembly and a second end coupled to the secondary frame of the second cleaning assembly and adapted to force the scraping heads of the first and second cleaning assemblies into said cleaning positions adjacent opposing sides of a rail to be cleaned.
