Patent ID: 6956159

Claim:
A drum system comprising, in combination: a drum shell of generally cylindrical configuration; a drum head of generally flat circular configuration and being adapted to rest upon the upper extremity of the shell; a ring shaped rim fitted over the outer circumference of the head, the cooperating surfaces of the shell and head being such that depressing the rim downwardly tends to increase lateral tension in the head; a tensioning rod having an upper end rotatably supported from a point on the circumference of the rim, and a threaded lower end; a lug assembly secured on the outer surface of the shell adjacent the lower end of the tensioning road and rotatable about a horizontal axis that extends radially relative to the shell; the lug assembly having a lug body with an upwardly directed opening adapted to receive the lower end of the tensioning rod; the lug body also having a transverse opening that intersects the top opening in a mutually perpendicular relationship; a cross-pin disposed within the transverse opening and movable both rotatably and longitudinally relative thereto; the cross-pin having a threaded transverse opening engageable by the threaded lower end of the tensioning; and the top opening in the lug body being of greater dimension than the threaded lower end of the tensioning rod in directions both perpendicular to and parallel to the adjacent surface of the shell.
