  • Patent number: 5076253
    Abstract: The burner is intended for combustion of wood logs or other similar solid fuels. The burner which will be called the basket burner is shaped as an open inclined basket (1) comprising a bottom plate (3) and a backing plate (4) which are inclined towards the horizontal plane, respectively the vertical plane, so that the connection between the bottom plate and the backing plate constitutes the lowest part of the basket. The backing plate forms a chute or hold for the package of wood logs. The two plates contain holes (8) for air. The fuel is piled up against the backing plate and is supported by the bottom plate so as to form a compact bundle or parallel wood logs with minimized surface/volume ratio. The design of the basket burner makes the wood logs serve as efficient supporting burners for each other. Thanks to the shape of the basket burner the burning wood logs are successively brought towards each other and towards the lowest part of the basket burner during the combustion.

  • Patent number: 5009217
    Abstract: A fireplace log holder and alarm system is designed for placement within the firebox of fireplaces. The log holder is comprised of parallel log supports having a very rough top surfaces so as to minimize rolling and slippage of the logs. Attached to the front of the log supports is the alarm mechanism which includes metal uprights having eyes in their upper ends. An elongated hollow metal tube spans the eyes of the uprights and is loosely received within them. During the course of combustion as logs shift and are partially consumed, any forwardly shifting log will precipitously contact the metal uprights or the metal tube and cause the tube and uprights to strike together. This rapid striking action generates a loud noise which serves to notify the occupants of the dwelling that log shifting has occurred and that a dangerous repositioning of burning logs demands their attention.

  • Patent number: 4862871
    Abstract: Combustion of horizontally-stacked fireplace logs is expedited and facilitated by maintaining the adjacent logs in a spaced-apart relationship, at least until proper combustion of the individual logs has been initiated. This enables the surfaces of the individual logs to rapidly reach combustion temperatures upon exposure to open flames from paper or other burning tinder or exposure to an underlying bed of glowing embers. The spacing of the logs can be readily accomplished by use of spacer devices. Preferred devices are members having a generally Y-shaped configuration in vertical cross-section so that the member has (i) a trunk portion adapted to be interposed in an upright position between two adjacent laterally positioned logs to provide spacing therebetween, and (ii) a pair of upwardly and outwardly extending arms forming an upper surface adapted to support or cradle another such log above, between and spaced from those two laterally positioned logs.

    Abstract: Andiron for supporting logs on a hearth in two primary fuel banks disposed in an inverted V-position to form triangular opening facing room to be heated. Andiron has horizontal baffle member supported above and between spaced positioning members by frame means. Baffle member and positioning members on each side of andiron are positioned so that primary fuel banks extend between edges of baffle member and positioning members so as to be inclined at particular angles with banks almost touching at apex. Secondary fuel placed between lower ends of primary fuel banks when ignited cooperates with primary fuel to form a concentrated, triangular-sectioned combustion zone of essentially uniform temperature defined by burning faces of primary and secondary fuel. Primary fuel burns mostly on inner faces with negligible burning of outer faces which reduces convection losses up the chimney.

  • Patent number: 4058108
    Abstract: A log-burning grate comprising a log-supporting portion and a log-retaining portion disposed at essentially ninety degrees to each other and supported by legs above a base plane with the support portion comprising a plurality of spaced apart members disposed at an angle of twenty to thirty degrees to the horizontal. A plate member is mounted to the retaining portion to control the position of the buildup of an ember bed, to slow the rate of burn, and to protect the back fireplace wall. The support members are spaced a sufficient distance to allow embers from logs in the grate to fall through and form a bed thereunder, the total area of spacing between said supporting members being substantially greater than the area of said supporting members so as to permit heat due to burning of logs in said grate to radiate outwardly from the front of the grate.

  • Patent number: 4029078
    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.
