Limekiln.
' Patented May 21, 1867.
UNITED STATES PATENT- OFFICE.
GEORGE ATKINS, OF SHARON, PENNSYLVANIA.
IMPROVEMENT IN LIMQEKILNS.
Specification forming part of Letters Patent No. 64,827, dated May 21, 1867.
To all whom it may concern:
Be it known'that I, GEORGE ATKINS, of Sharon, in the county of Mercer and State of Pennsylvania, have invented a new and useful Improvement in Limekilns; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1 is a central vertical section of my improved limekiln, taken through an upper tier of furnaces in the line as m, Fig. 2; Fig. 2, a central vertical section of the same, taken at right angles to the section, Fig. 1, and through a lower tier of furnaces in the line y y, Fig. 1.
Similar letters of reference indicate like parts.
This invention relates to an iIDPI'OXGd mode of constructing kilns for burning lime;'and consists in forming the bosh of the kiln in the shape of a truncated cone, based on an inverted cone, similar in its general conformation to that of a blast-furnace, and provided with two tiers of furnaces, which extend into the body of the kiln and open directly into the chamber, to throw the heat uniformly throughout the mass of limestone contained therein, and thus burn the lime better. The main chamber or part of the kiln above the bosh being smaller at the top than the bottom, room for expansion of the stone by the heat is provided for, and it gradually settles as it is discharged without choking the draft, to which straight-sidcd kilns are liable. Upon this plan a large limekiln can be built to work successfully, which cannot be done with a straight-sided kiln having the furnace-fires externally placed with respect to the chamher.
The kiln is built economically of fire-brick on the inside as a lining, a, inclosed in a casing or shell, I), of sheet or boiler iron or it may be constructed of mason-work entire from the foundation. An upper section, A, is made wholly of an iron casing, b, and, resting upon the brick-work, is secured to the casing b below. The body or main chamber B of the kiln enlarges gradually from the top to the bottom, and at the widest-part or bosh the furnaces G .O are set on opposite sides, running into the kiln and opening in the chamber B, as shown in Fig. 1. At this point the lower section D tapers off very rapidly, like an inverted cone,
down to the discharge-opening E, which drops the lime into the draw-chamber F. And at the bottom of this lower section D two other furnaces, G G, are set on opposite sides, and
. at right angles to the furnaces O O, projecting like them into the kiln, and discharging the products of combustion directly into the chamberD among the limestones therein. Directly over the furnaces G O, and in the same level with the upper furnaces O O, are placed two doors, G G, for the purpose of admitting a steam-boilers. In my improved limekiln I employ flat wrought-iron or cast bars, so that they can be drawn out with tongs and cleaned,
easily.
Having thus described my invention, I claim as new and desire to secure by Letters Patent- The arrangement of a limekiln formed of the chambers A B D, and heated by furnaces 0 O at different levels'inside the kiln, operating substantially as and for the purpose herein described.
GEORGE ATKINS.
