Claim:
A vacuum driven sander comprising, a housing formed from a rigid material that includes internal air inlet passages connected into a turbine chamber, a bearing assembly cavity wherein a pair of bearings are mounted that support a vacuum air driven turbine, an output shaft of said turbine connects to an eccentric that provides an orbital motion to a sanding plate, with the vacuum flow vented from said housing through a port centered in said housing top and into a hollow bent exhaust tube; pivoting joint means for mounting said hollow bent tube across said port that has spaced radial cavities formed around said port center and including, as a first pivot mount, a collar having an internal curved section that receives a ball section end of said hollow bent tube as a ball and a lower surface of said collar includes a ball section for fitting into a curved surface of said port, and which said collar includes a pair of stub axles that are spaced equidistant from one another and project oppositely from said collar outer surface that are each for fitting into one of each of a pair of said spaced radial cavities formed around said port, with said first pivot mounting that allowing said housing to be pivoted up and down on said hollow bent tube end, and said collar further includes a pair of ears that are spaced equidistantly apart and extend outwardly from a collar rear edge, and have holes formed therethrough that align with, to individually receive, each of a pair of lugs that are equidistant from one another and extend outwardly oppositely from said hollow bent tube end, forming a second pivot mounting that allows said housing to be pivoted from side to side across said hollow bent tube end; and cap means having a center opening that is to pass said hollow bent tube therethrough and mount over said port, maintaining said collar sub axles in said spaced radial cavities.
