    Provisional Naylor s Improvements in the Prevention or Consumption of Smolce. one or more steam jets, and with an orifice for the admission of air, such orifice being provided with a self-acting valve, which is sufficiently weighted to close or nearly close when the steam jets are not on, but to open by the inrush of air to the pipe when the steam jets are applied. The opposite end of this pipe separates into two branches, the one branch being connected to 5 the mouth of the hot air conduit or chamber above referred to, so as to convey air thereto, whilst the other branch is connected to an inverted syphon which is partly filled with water, such syphon serving to collect and carry off any water of condensation which may be produced in the pipe, and thereby prevent it from being blown into the hot air chamber or conduit. By this 10 means a powerful current of air is caused to pass through the hot air chambers or conduits, and such air after being highly heated in its passage through the said chambers or conduits enters the furnace through apertures for that purpose, and mixes with the unconsumed gases as they rise from the fresh fuel, thereby effecting their combustion and preventing the formation of 15 smoke. In some cases the air branch of the pipe or air inducer above described may be made to inject the air directly into the chimney or stack, either at the bottom thereof, or through openings made for that purpose in the sides at any desired height above the ground, by which means a powerful blast is produced up the chimney or stack, the object being to compensate for 20 the retardation of the draught produced by the cooling effects of the air in the chimney by imparting increased velocity to such air. In lieu of steam jets other well-known means may be employed for producing a current of air, as for example, a fan blower, bellows, or blowing cylinder. As the inlet of air into the furnace or stack is only required during the time that the fuel is 25 giving out unconsumed gases, which would otherwise result in smoke, 1 propose to adopt suitable self-acting arrangements for closing or partially closing the air inlets and the steam jets (when employed), such arrangements being so disposed that before the mouth of the feeding aperture of the furnace can be opened for the admission of fuel the air inlets and steam jets (when 30 used) shall be opened or brought into play. One mode of effecting this consists of a lever working on a fulcrum, and carrying at one end a dead weight, whilst at its opposite end it carries a bucket or vessel which rises and falls in a cistern of water, such vessel having a perforation in the bottom. The dead weight preponderates slightly over the bucket or vessel when empty, and 35 when the lever is in its normal position and no air is admitted to the furnace the weight will be immediately in front of a flap or grating covering the mouth of the feed aperture, and consequently all access to the furnace is prevented until the weighted end of the lever is lifted out of the way, so as to
