Abstract
An instrument support device for adjustably receiving a member of a support plate having an outer spherical surface wherein the socket, formed integrally, is an outer and upper ring portion connected to an inner and lower ring portion by intercrossed ribs with upper surfaces of the ring portions and ribs defining segments of a conical surface capable of cooperating with spherical surfaces of differing radii. The lower surface of the socket forms a substantially spherical clamping surface, such that a locking knob can draw a range of spherical surfaces into a clamped relation with the conical support surface. The socket forms a tripod head by having lugs on the upper ring portion that extend out and embrace the elements of the tripod legs so that the tripod legs are mounted from the outside of their respective elements.
