Description: |
| Most of the patents prior to 1836 were lost in the Dec. 1836 fire. Only about 2,000 of the almost 10,000 documents were recovered. Little is known about this patent. There are no patent drawings available. This patent is in the database for reference only.
“For an improvement in the art of Constructing and Building Lime Kilns, for the purpose of burning lime; Louis Bomeisler, Philadelphia, Pennsylvania, September 10.
Particular directions are given in the specification of this patent respecting the dimensions of this kiln, the height of which is to be about 16 feet, and its greatest diameter nearly 14, its form is egg shaped. There are no particular points claimed, although several provisions are pointed out which are said to render it superior to other kilns, such as the manner of supplying air to produce a more equable heat, and a more perfect combustion than has hitherto been obtained; it is also said that the mode of building certain parts serves to shelter the workmen who feed and tend the fire. The principal improvement proposed, is, the employment of that heat which is usually permitted to run to waste, and the consumption of that portion of the fuel which is ordinarily allowed to escape in the form of smoke, but which, by a due supply of air, is caused to burn, in consequence of which it leaves the kiln in the form of flame, and is thence conducted into another kiln, or oven, for the purpose of burning brick. The crown of the lime kiln is left open, to charge it with stone, the diameter of the opening being 7 or 8 feet: there is a cap, or cover, to this opening, which is to be lifted on and off by a crane, or sweep; this cap, or cover, has an opening in its centre, of three feet in diameter, to receive a sheet-iron pipe, which is to conduct the flame into the oven, or kiln, containing the bricks; the structure of which is such as to cause the flame to circulate in it in such manner as is deemed most advantageous. The heat which escapes in using twenty cords of wood, the quantity necessary to burn fourteen or fifteen hundred bushels of lime, it is observed, is enormously great; the improved kiln is stated to save this heat, by applying it as above mentioned. The heat thus communicated will be sufficient to burn such bricks as do not require a greater heat than that which is necessary for the burning of lime, and any additional heat may be obtained by obvious means, if necessary. The result of this improvement, is, to convert to profit a considerable part of the heat hitherto lost, and to reduce the quantity of fuel necessary to burn lime
A more particular description would require a drawing; that which accompanies the patent affords but an imperfect representation of the kiln, being merely a rough outline section.”
