  • Patent number: 5823175
    Abstract: A thermal protective barrier is provided for space heating units in the form of a relatively thin panel having an interior volume filled with a non-combustible liquid (water and/or antifreeze mix, etc.). Two of the embodiments are flat and are adapted to be placed beneath and about the sides of a stove or other heating unit, with a third embodiment having a toroidal cross section and being adapted for installation about the flue of such a stove or heater. Additional structure may be installed within the panels to provide additional support, as required. The panels may be removably installed between the stove and adjacent walls and the underlying floor, or may be permanently installed integrally with the building structure. The panels may also include decorative coverings for exposed surfaces, if desired. The panels may be independent of other water or fluid systems, or may be interconnected with a water heater or hot water heating system, if desired.

  • Patent number: 4475533
    Abstract: A freestanding stove is provided including an elevated firebox mounted atop a tubular pedestal having a horizontally enlarged downwardly opening hollow base at its lower end. The firebox includes a combustion air inlet opening downwardly into the pedestal and the lower end of the pedestal opens downwardly into the hollow base which includes a damper for controlling the flow of combustion air from within the hollow base into the lower end of the pedestal. The base includes feet supporting the base a spaced distance above a horizontal surface upon which the feet rest and the feet are removable whereby the base may rest directly upon and over a horizontal support surface upwardly through which a combustion air opening is formed. The front of the firebox includes an openable transparent window equipped door and combustion air inlet passage structure for sweeping curtains of combustion air across the inner surface of the window from selected marginal portions thereof.

  • Patent number: 4418679
    Abstract: A mounting kit for stove boards includes ceramic spacers separating the board from a wall so that cool air can circulate behind the board and spacing cradles supporting the board off the floor so air can additionally flow beneath the board. Mounting brackets touch only ceramic surfaces of the spacers so that there is no metallic conduction of heat into the wall.

  • Patent number: 4416251
    Abstract: A thermoshield primarily intended to be used for protecting a wall from the heat that may develop by a free-standing heating appliance or space heater that may be situated in proximity to the wall. However, certain structure of the device may be adapted to be used for restingly supporting thereon the heating appliance, thus protecting a floor from the heat developed thereby. The thermoshield features a sub-assembly of particular construction which serves as a heat barrier in either of the above mentioned dispositions, and peculiar support structure for supporting the sub-assembly in place between the heating appliance and the wall to be protected. A significant feature of the support structure is that the sub-assembly remains absolutely unaltered by the implementation of the support structure.

  • Patent number: 4399805
    Abstract: Protective panels are disclosed for insulating walls and other combustible surfaces from a nearby stove or other heating device. Simple, economical shallow U-shaped pieces, one positioned upon the other, create two distinct conduits through which air flows upwardly. Also, the panels reflect radiant heat back towards the stove or other heat source and away from the area protected. A plurality of these double conduit panel members provide an insulating barrier between the heat source and the combustible surface to cover areas of any desired size.

  • Patent number: 4274393
    Abstract: A new fireplace assembly is provided which is inserted into a conventional fireplace and which is capable of greatly increasing the burning efficiency and heat output over conventional units, decreasing the waste heat lost and at the same time providing a unit which is as pleasing from an aesthetic standpoint as a conventional fireplace. The assembly of this invention includes a firebox in which combustion is maintained and mounted on the hearth of a fireplace, the firebox having doors in the front thereof opening into the combustion chamber, the doors having adjustable draft means therein to control the amount of air introduced to support combustion, a smoke outlet box mounted on the rear of the firebox and extending into the fireplace opening, the firebox having controllable damper means for conveying smoke from combustion to and up the chimney of the fireplace. The opening into the smoke outlet box is at least partially covered by a spark shield.

  • Patent number: 4219007
    Abstract: A hearth-like base portion has a top stove supporting wall spaced above the supporting surface to provide an insulating area below the stove. Also, an upright firewall portion is secured to the rearward end of the base portion and has a face plate arranged to be spaced from the wall of a room to provide an insulating area behind the stove. Air circulation passageways are provided in the base and firewall portions for cooling. The discharge of heat from these portions may be upward by convection or in a reverse direction by a powered blower. A removable mantle is supported on the top of the firewall portion.
