Apparatus for machining work pieces

Claim 1

Apparatus for finishing the surface of work pieces and defining a plurality of horizontally spaced apart work stations arranged in a circular pattern, comprising discrete machines respectively disposed at certain of said work stations, at least two of said machines each including a rotatable member with a horizontal operating surface for engagement by work pieces, carrier means supported independently of said machines and including a circular carrier member revolvable horizontally above said work stations, a plurality of circumferentially spaced apart groups of horizontally disposed plate means with the number of groups corresponding to the number of said work stations and to which work pieces are adapted to be secured on the underside thereof, a plurality of groups of vertically disposed power actuated means carried by said carrier means and respectively connected to said plate means for selectively raising and lowering the latter, each group of said power actuated means selectively serving to transfer the associated group of said plate means and work pieces secured thereto progressively from one of said work stations to another of said work stations upon movement of said carrier means, and the groups of said power actuated means overlying said two machines selectively serving to apply downward pressure on said plate means to forceably urge the work pieces secured thereto against said horizontal operating surfaces of said rotatable members.
