Abstract: The wheeled “X”-frame table dolly has a “U”-shaped guide member extending forwardly and rearwardly from a “U”-shaped cross member at a center point. The guide member has swivel castor wheels at its front and rear ends and at its center. The cross member has fixed castor wheels for its support. The cross member also has matching grooves and wing-nut fasteners for mounting extensions and varying their length on each side of the guide member so as to carry a variety of tables having differing widths between the end legs thereof. Extensions having fixed forward and rear directional castor wheels support the added weight. The extensions are withdrawn inward for compactness for storage. A folded table may also be carried on its side in the guide member as desired. Carpet portions or other padding are included to cover the carrying surfaces of the guiding member cross member and extensions.
