Filed:

Nov 23, 1977

Appl. No.:

5/854414

Inventors:

Donald S. Simms - Leyden MA

International Classification:

F24B 502

US Classification:

126123

Abstract:

The within invention comprises a stove unit or fire box to be used to heat the inside of buildings. It is particularly designed to be used inside the hearth of fireplaces. It has slots and openings in its panel flanges for permitting the panels to be adjusted so as to change the locations of the panels to cover the area in the front of the fireplace both on the sides and top of the stove unit so that only the glass doors of the combustion chamber or fire box will be seen and the inside of the fireplace cavity will be hidden from view. The panels, and the location of the slots and openings are so arranged and are of such dimension to permit the unit to fit most sizes of fireplaces. The unit also has an air intake duct which converts the cool air, heats it and jets it out into the area to be heated. The air intake system is designed by reducing the cross-section of the air intake duct causing an increase in the velocity of the warm air that is transmitted from the unit, eliminating the need for a blower, and saving the use of electricity. The cool air is drawn in from openings located at floor level at the bottom of the unit and travels through an outer sleeve around the fire box whereby it is heated.

Abstract:

This invention is concerned with a removable filter to prevent the buildup of Creosote in chimneys which become vulnerable to fires. A hollow enclosure means that is adapted to connect between the chimney and the fire source has within it a support for mounting a filter. The filter is made of a special metal, is knitted with small openings therein permitting the flow of smoke but at the same time to reduce the particles into a minute white ash. The filter acts as a continuous burn reactor. A door is provided whereby the filter can be easily removed from the hollow enclosure and cleaned so that it can be used for an indefinite period without replacement.
