Abstract
A work tool machine comprises a power tool, an exhaust hood assembly disposed over the power tool in a manner to permit access of a work piece thereto, and a stationary member spaced from the hood assembly. An elongated guide bar extending between the stationary member and the hood assembly is pivotally attached at one end to the stationary member for rotation about a first axis, and at the other end to the hood assembly for rotation about a second axis. An elongated conduit extending between the stationary member and the hood assembly in fluid communication with the hood assembly is pivotally attached at one end to the stationary member for rotation about a third axis, and at the other end to the hood for rotation about a fourth axis. The distance between the first and second axes is equal to the distance between the third and fourth axes, and the distance between the first and third axes is equal to the distance between the second and fourth axes. The conduit is connected to an exhaust fan.
