Patent number: 5076253Abstract: 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.Type: GrantFiled: May 15, 1990Date of Patent: December 31, 1991Inventor: LindstroOlle B.
-
Patent number: 5009217Abstract: 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.Type: GrantFiled: April 9, 1990Date of Patent: April 23, 1991Inventor: Hewitt M. Johnson

Patent number: 4886445Abstract: A gas burning artificial log assembly includes an artificial log set, a gas burner and andirons for support of the artificial logs. Each of the artificial logs has a front face and a different rear face and can be reversed so as to change the appearance of the artificial log set. The faces of the logs can simulate different wood types or can have a partially-burned appearance. The artificial logs are shaped to define a combustion chamber that promotes complete gas combustion and provides a realistic-appearing gas flame. The gas burner includes a burner pan and a T-shaped manifold that define a pair of adjustable-width rear gas exit slots for producing a rear flame between the logs and further define a front gas exit slot for producing a front flame. The exit slots can be adjusted in width to insure complete combustion for different gas type such as propane and natural gas. The andirons, the gas burner and the artificial logs are keyed to insure proper alignment.Type: GrantFiled: November 2, 1987Date of Patent: December 12, 1989Assignee: Vermont Castings, Inc.Inventor: Stephen F. Richardson

Patent number: 4862871Abstract: 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.Type: GrantFiled: April 11, 1988Date of Patent: September 5, 1989Inventor: James F. Sieberth

Patent number: 4773387Abstract: Newspaper or the like is prepared for burning by folding and rolling operations to provide its complete combustion. The paper is folded such that one edge is placed parallel to and spaced from the opposite edge. The folded paper is then rolled to form a cylindrical fuel element. The cylindrical fuel element is advantageously placed in a fixture retaining its rolled and folded condition during binding. The fixture includes a first and second end supports forming a rectangular channel receiving the cylindrical fuel element. A connecting member maintains the supports relative to each other. A constricting member is positioned in the channel which reduces the width of the channel to maintain the fuel element in its rolled condition. The fuel elements may be in the form of kindling sticks, or bundles of such sticks, or individual logs.Type: GrantFiled: November 17, 1986Date of Patent: September 27, 1988Assignee: A.

Patent number: 4723534Abstract: A combination fuel holder and draft channel device for use in a fireplace or wood burning stove. The fuel holder in this combination is made from 1/8 inch steel plate and its size, as well as the size of the draft channel, may vary according to the size of the fireplace or stove in which it is to be used. The fuel holder consists of a base plate that lays flat on the bottom of the firebox of the fireplace or stove. Two vertical posts, each 3/4 inches wide and 6 inches high are welded on the forward edge of the base plate, each 2 inches from the center. These posts hold the wood fuel, resting on the base plate, in a compact and manageable pile for controllable combustion. The draft channel is placed between the posts and is held in position by them. The posts add versatility to the holder because pieces of 1 inch conduit pipe can be cut in lengths desired and slipped over the posts to provide added holding capacity. The draft channel is made from the same steel plate as the fuel holder.Type: GrantFiled: November 13, 1985Date of Patent: February 9, 1988Inventors: James A. Little, Blanche M. Little

Patent number: 4131108Abstract: 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.Type: GrantFiled: January 17, 1977Date of Patent: December 26, 1978Inventor: Edward M.

Patent number: 4029078Abstract: 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.Type: GrantFiled: August 30, 1976Date of Patent: June 14, 1977Inventor: Robert E.
