    Smith’s Improvements in Consuming Smoke, fyc. communicate at their inner extremities with a closed space or chamber E, into which the front end of the fire-bars C are introduced, as more particularly seen at Eigure 1. The air on its passage through the tubes A becomes heated, and is in that state conveyed from the space or chamber E through the fire-bars C, which are made with channels or passages 5 through them to the hollow bridge I), and is delivered therefrom through openings c, formed either at the top of the bridge, as shewn at Eigures 1 and 2, or at the sides or back thereof, to the smoke and products of combustion passing off from the fuel in the furnace or fire¬ box B, which are thereby burned or consumed. 10 The air tubes A at their outer extremities are connected to a tube E, communicating with a blowing fan G, as shewn at Eigure 4, for blowing or drawing air through the apparatus, or in lieu of such arrangement a steam jet may be employed to induce a current through the tubes A, space or chamber E, fire-bars C, and bridge D; or a blowing fan and steam 15 jet may be used jointly. Instead of employing heated air to promote the combustion of the smoke at the bridge D, steam superheated by being passed through the tubes A may be employed for that purpose. One or more doors may be situated in the front of the space or chamber E in order to facilitate 20 cleaning operations by passing a brush or other instrument into and through the chamber and hollow fire-bars. It is to be here understood that although I have for the sake of illustration shewn my Invention on the accompanying Drawings as applied to the furnace or fire-grate of a horizontal boiler, I do not limit 25 or confine myself to employ my said Invention in conjunction with the furnaces or fire-grates of boilers, whether horizontal or otherwise, as it is equally applicable for employment in effecting the burning or consuming of the smoke or products of combustion proceeding from furnaces or fire-boxes generally. 30 Having now described and particularly ascertained the nature of my said Invention, and the system, mode, or manner in or under which the same is or may be used or practically carried into effect, I would observe in conclusion that what I consider to be novel and original, and therefore claim as the Invention secured to me by the herein-before in part 35 recited Letters Patent is, the arrangement or construction of apparatus
