    Provisional Loft us Improvements in Smoke-consuming Apparatus. means of which the admission of atmospheric air is regulated to a given time or period in which the smoke shall be wholly consumed. Attached to the outside of the framing of the furnace door is a quadrant in which works a stud, to which is attached the lever and connecting rod before mentioned, which open and close the air valves, and also move the combustion bar. To 5 this quadrant is also attached a pillar, bracket, or pedestal supporting the self- acting adjusting balance, which is attached to the lever working the air valves and combustion bar by a rod. This self-acting adjusting balance consists of a hollow metal box or case, in which is placed a sufficient quantity of shot to cause the balance to fall back gradually to its original position after the closing 10 of the furnace door. The whole apparatus is set in operation by the opening of the furnace door, to which is attached a projecting piece of metal of any convenient shape. On opening the furnace door the projecting piece of metal is brought into contact with the rod attached to the self-acting adjusting balance, causing the said balance to fall over, by which movement the lever 15 and connecting rod attached to the air valves and combustion bar is set in motion, the air valves are opened, and the combustion bar brought into action, - causing the smoke to ignite and consuming it at once. On closing the furnace door the self-acting adjusting balance (regulated by shot which pass through a hinged grated door) gradually falls back to its original position after the smoke 20 is consumed.
