Having described the nature of our Invention, and the manner of carrying the same into practical use, we desire it to be understood that we do not confine ourselves to the precise arrangement of the details as herein described and shown, as the same may be varied without departing from the Invention; but what we claim, and desire to secure under the herein-before in part recited Letters Patent is,— Firstly, the mechanical arrangements for consuming smoke, as shown and described in reference to Figs. 1 to 6 of the accompanying Drawings, or any mere modification thereof. Secondly, the arrangement for consuming smoke, as shewn by Figs. 7 and 8, and herein-before described, or any mere modification thereof. Thirdly, the arrangement for consuming smoke, as shewn by Fig. 9, and before described, or any mere modification thereof. In witness whereof, I, the said James Henry Wheatley, have hereunto set my hand and seal, this Seventh day of September, One thousand eight hundred and fifty-five. JAMES HENRY WHEATLEY, (l.s.)
