Abstract
The andiron comprises four corner posts and upper and lower sets of horizontal log support bars. The lower bars are continuous and are adapted to support a plurality of logs in a horizontal position above the floor of a fireplace. One of the upper bars is continuous and the other is open at its center. The open centered bar has two end portions, each of which is adapted to support at least one log in a horizontal position above the lower logs. The open center permits one or more additional logs to be placed diagonally, with the lower ends(s) thereof on the lower set of logs and the opposite end(s) on the continuous upper support bar. The sloping attitude of the additional log(s) facilitates both its ignition and the ignition of the upper set of logs. As the logs burn they eventually break at their centers and fall downwardly into the confines of the andiron, usually into diagonal positions with their outer ends supported on one of the cross members.
