A universal attachment flange to connect equipment utilized to perform a task to various connection arrangements. A universal attachment flange is provided with a plurality of hole patterns to permit a bolted attachment of the flange to other devices that present varying patterns of bolt receiving holes. The universal attachment flange is capable of connection to a variety of four (4) hole patterns and at least one three (3) hole pattern. In one form the universal attachment flange includes a through hole threaded to receive a connection fitting.

I claim: 1. A universal attachment flange adapted to connect to an attachment flange receiving connection, said universal attachment flange comprising:a body defining a pair of spaced apart faces, one of said faces adapted to be secured to the attachment flange receiving connection in face-to-face relation,a pattern of through holes extending completely through said body between said faces,said pattern comprising a combination of through holes configured to align with a plurality of different hole patterns presented by various attachment flange receiving connections,said pattern defined by holes formed on an outer bolt circle BC1, a middle bolt circle BC2 and an inner bolt circle BC3 wherein said bolt circles are concentric and coaxial with a centerline perpendicular to said faces,said pattern including four elongated holes having a radially outer semi-circular end surface defined by radius R struck from a point P where four radial lines, ninety degrees (90°) apart, extending from said centerline perpendicular to said faces intersect said outer bolt circle BC1, and a radially inner semi-circular end surface defined by radius R struck from a point P where one of said middle bolt circle BC2 or inner bolt circle BC3 intersect each of said four radial lines, said radially outer semi-circular end surface and radially inner semi-circular end surface of each of said elongated holes joined by parallel side wall surfaces spaced apart a distance two times said radius R,said pattern further including two circular holes adjacent, and on either side of one of said four elongated holes, each said circular hole formed by said radius R struck from a point P where a radial line from said centerline perpendicular to said faces and spaced from one of said four radial lines ninety degrees (90°) apart intersects said middle bolt circle BC2 or said inner bolt circle BC3.
