Claims30
A fireplace hearth apparatus for producing a flame and comprising
- a snuffer;
- a fuel tray oriented beneath said snuffer;
- said fuel tray being movably mounted to said apparatus for downward and lateral movement for filling and said fuel tray being laterally movable under said burner element and upwardly for operative engagement with said burner member.
A fireplace hearth including a roof disposed over a fire area, said roof comprising:
- an upper roof panel;
- a heat shield under said roof panel;
- said heat shield defining an air flow space between said roof panel and said heat shield;
- elongated openings defined by adjacent edges of said roof panel and said heat shield for ingress of ambient air;
- a vent disposed in said roof panel;
- and
- the space between said heat shield and said roof panel being unobstructed, such that air freely flows from said elongated edges to said vent without obstruction in said flow.
A freestanding fireplace hearth having a bottom, a plurality of sides, a roof, a snuffer and a movable fuel tray mounted operably beneath said snuffer and being movable laterally for fueling, said tray movable upwardly for sealing engagement with said snuffer when disposed thereunder and movable downwardly away from said snuffer when pulled laterally for refueling, said hearth further having a plurality of posts defining corners, each post having an elongated slot therein for receiving and holding an edge of a glass side of said hearth, and said elongated slot having an elongated groove therein for receiving a tenon of a structural side member therein above said glass side.
A free-standing fireplace hearth for burning a fuel to provide ambiance fire, the system comprising:
- a base having a drawer slidably mounted therein for movement between open and closed configurations;
- a spring biased latch to releasably secure the drawer in the closed configuration;
- a tray moveably mounted in the drawer and adapted to receive therein the fuel, the tray being mounted for movement between a lowered and a raised position;
- a plurality of links pivotally coupled at a first end to the drawer and pivotally coupled at a second end to the tray;
- a stop mounted on the base relative to the drawer and the tray so that as the drawer approaches the closed configuration the tray abuts against the stop and continued movement of the drawer toward the closed configuration pivots the links and thereby elevates the tray relative to the drawer into the raised position and sealing contact with a flue;
- a pair of spaced damper shutters mounted for movement to and between a closed snuffing configuration and a fully open configuration, each of the damper shutters being coupled via a linkage to a rotational control knob such that rotation of the control knob in a first direction pivots the damper shutters toward the closed snuffing configuration and sealing contact with the tray and the flue to extinguish the burning fuel and rotation of the control knob in a second direction pivots the damper shutters toward the fully open configuration to allow increasing amounts of air to the burning fuel;
- a plurality of posts extending upwardly from the base;
- a cover supported by the posts;
- a heat shield mounted interiorly of the cover to deflect hot air generated by the burning fuel from impinging upon the cover and maintain the cover at a lower temperature than the heat shield during fuel burning, at least a portion of the heat shield being spaced from the cover to permit an insulation layer of air between the heat shield and the cover;
- and
- a plurality of baffles in the heat shield to direct the hot air from the heat shield and cooler air into the insulation layer of air between the cover and the heat shield.
A fireplace hearth comprising:
- a laterally movable fuel tray defining a volatile fuel chamber,
- a constricting throat in said fuel tray above said chamber;
- a snuffer;
- said tray being operably oriented beneath said snuffer;
- a wedge-shaped diverter in an upper portion of said snuffer and defining two openings;
- an adjustable damper movable toward and away from each said opening to adjust the size of said openings in a plurality of flame burning positions and to close off each respective opening;
- a log set disposed above said snuffer, said log set having a plurality of flame passages therethrough for receiving flame from openings in said snuffer and for receiving air from outside said snuffer,
- said air mixing with and lifting said flame through said log set.
A crackling gel fuel comprising a fuel source, a gelling agent and encapsulated solvents said encapsulated solvent having a size and composition effective to maximize crackling sound when burned.
A water soluble fuel composition providing a golden flame and generating a crackling sound without excessive smoke comprising:
- a flammable lower alkyl alcohol;
- a flammable non-aromatic organic compound effective to produce a golden flame during combustion;
- microcapsules containing a flammable organic solvent different from said non-aromatic organic compound and said lower alkyl alcohol.
A water soluble fuel composition which, when burned, provides a golden flame and a crackling sound without excessive smoke comprising:
- a flammable lower alkyl alcohol in an amount effective to enable said fuel to maintain a self-contained flame;
- a flammable non-aromatic organic solvent effective to produce a golden flame, said solvent selected from the group consisting of aliphatic hydrocarbons and yellow burning alcohols and mixtures thereof;
- water soluble gelling agent comprising a polyacrylic acid and water;
- and
- microcapsules of an aromatic solvent.
A fuel composition comprising:
- 50% to 65% by weight ethanol;
- 2% to 15% by weight aliphatic hydrocarbon having an aniline point about 180 degrees F.;
- 0 to 12% tertiary butyl alcohol;
- an amount of microencapsulated flammable aromatic compound effective to cause a crackly sound when burned;
- and
- a gel composition comprising water and a polyacrylic acid or salt thereof in amounts effective to establish a viscosity effective to suspend said microencapsulated flammable aromatic compound.
