    • 204,999. Anker Heegaard Aktieselskab, Paulsen, A., and Moller, J. P. Jan. 23, 1923. Draught, regulating; grates; open fire-places; outlets to chimneys.- The draught in a fireplace is controlled by two pivoted members i, k, one being in rear of the other, co-operating with a partition f and forming two channels leading to the outlet h; by adjusting the members to the positions indicated respectively by the numerals 1, 2, 3, the combustion products may be made to pass wholly in front of the member i and above the partition f, or partly in front of and partly behind the member i, or wholly behind the member i through a circuitous passage below the partition f. In the construction shown, the member k, the lower part of which is provided with side wings and forms a canopy, is connected to the member i through an arm p on the latter so that both members are operated simultaneously. The stove shown is provided with a basket grate a the bottom of which is formed by a rotatable sifter b. The outlet connection h is screwed in order that it may be adjusted in height to connect with the flue.
