    Ue Chabannes Improvements in Regulating the Temperature of Houses, $c. disposed in such a manner in a flue of the same or other suitable materials as to suffer the air to pass freely between them; beneath these bricks is placed a small grate for the purpose of receiving and consuming any part of the fuel which might fall thro’ the space left between the bricks. This grate is fur¬ nished with an opening for the purpose of clearing the ash hole or lighting the 5 fire in case the air pump be not used; this opening is also calculated to admit fresh air to consume what may remain of the fuel, as well as to burn the gas which may have escaped combustion in its descent thro’ the mass of bricks which are placed upon an open arch of the same or other proper materials so as to support the fuel on their summit; or in lieu of the above-described 10 furnace may be used the calorifere fumivore, for which I lately obtained Letters Patent. When the air pump or pneumatic machine is used for the purpose of forcing a current, the superficies of the object to be heated may be augmented to any extent, and the whole of the caloric produced by the fuel may be employed either on the liquid or on the air to be heated, as part of it being wanted to form a 15 current in the flues or chimnies. My method of cooling air is by means of the air pump and ventilator before described, either jointly or separately, causing the air to pass through a cool medium ; and my method of cooling liquids is fully shewn in the annexed Drawing of the cooling apparatus, and the descrip¬ tion thereof. From the above Specification, which I have endeavoured to make 20 as explicit as possible, I have no doubt but any scientific person will be able fully to understand the nature of my Invention; but as a further elucidation, I have annexed Drawings of the air pump or pneumatic machine, of the apparatus for heating and evaporating liquids, of the cooling apparatus, and of the ventilator; also of the method of heating ovens and hothouses, drawing rooms, &c; but in 25 giving these Drawings, I do not attach more importance to the exact forms therein shewn, or to the materials of which they are composed, than to any other capable of producing the same effects, as it is evident that the forms and materials may be varied in many ways according to the caprice of persons or the locality of the apparatus, SO Explanation of the Drawings.
