Abstract: Solid fuel combustion equipment in the form of a grate assembly comprises longitudinally extending support elements on which are mounted laterally orientated grate bars. The support elements are pivotable about their horizontal axes and are provided with sealing means at their adjacent margins to effect a seal to prevent in use passage of air when the elements are horizontally aligned. De-ashing of the grate assembly in use is achieved by tipping the support elements, whereupon ash falls to a receiving area when it is removed.

Abstract: A solid fuel burner having a housing with runners mounted inside its sidewalls and vertical rods passing upwardly through the runners which support two frames each having a shaker-grid opening therethrough with a shaker grid rockably supported therein, the shaker grids being capable of separate shaking so that one grid can support a coal fire and the other support a wood fire, and the frames having air slots therethrough offset from the grid openings with plugs for selectively closing them, and sideliner plates restable on the frames and leaning outwardly against the vertical rods between the grids and the sidewalls.
Abstract: Fireplace apparatus is disclosed in which combustion air is obtained from outside the structure in which the apparatus is installed and the apparatus is sealed from the structure in which it is installed and the heat from the fireplace is collected from around the fireplace and from above the fireplace in the chimney flue for transmission to other parts of the structure in which the fireplace furnace apparatus is installed for heating purposes.
