Abstract:
A burnishing apparatus for simultaneously burnishing opposing and laterally spaced surfaces of a work piece when the work piece is rotatably driven about a horizontal axis of rotation comprising, a fixed platform, a burnisher housing having an elongated tool support shaft operatively mounted thereto for turning movement about a vertical axis, a slide unit operatively disposed between said fixed platform and said housing to allow said housing to be laterally adjusted relative to said platform in a path generally parallel the axis of rotation of said crankshaft, said support shaft having a burnishing tool affixed proximate to the lower end thereof which is adapted to be moved into the space between said laterally spaced surfaces of said work piece, said tool having a pair of opposing burnishing members for operative contact with the opposing laterally spaced surfaces of the work piece for burnishing the surfaces when said work piece is rotatably driven about said axis of rotation, and opposing biasing construction operatively disposed between said fixed platform and said housing to move said housing to a predetermined position relative to said fixed platform so that said support shaft and the tool can be positioned between said surfaces and so that said tool can be subsequently turned to turn at least one of said burnishing members into physical contact with at least one of said surfaces to effect a resultant movement of said burnisher housing relative to said fixed platform and thereby position said support shaft and the burnishing tool supported thereby in a centered position between said laterally spaced surfaces so that said burnishing members can physically contact and simultaneously burnish both of said spaced surfaces when said work piece is rotationally driven about the horizontal axis of rotation.
