DANIEL J. FARRELL AND ANDREW T. LIEN, OF MASON CITY, IOWA,
ASSIGNORS TO FARRELL, WHITE & LIEN, OF SAME PLAGE. i
IMPROVEMENT lN LlNlEKILNS.
Specification forming part of Letters Patent No. 180,214, dated July 25, 113-76; application filed May`2'7, 1876.
To all whom it may concern:
Beit known thatwe, DANIEL J. FARRELL and ANDREW T. LIEN, of Mason City, in the county of Cerro Gordo and State of Iowa, have invented a new and useful Improvement in Limekiln, of which the following is a specication:
Figure l is a vertical section of our improved limekiln, taken through the line w fw, Fig. 2. Fig. 2 is a cross-section of the same, taken through the line .fr a, Fig. l.
Similar letters of reference indicate corresponding parts.
The object of this invention is to improve `the construction oi' limekilns; to give a much better application of the fire to the limestone than in kilns constructed in the usual way; to make the kiln air-tight, even should it crack; to avoid the use ot' heavy timber and rods for tying the kiln; to cause `the lime to drop evenly t0 the center of the draw, to avoid the necessity of drawing the'lime while atfa white or red heat, and to enable the lime to be dropped readily and surely.
The invention consists in providing the kiln with a case and filling the space between them with clay, t0 render the kiln air-tight, even in casek it should crack in consequence of the etl'ect ot' excessive heat. The invention further relates to a device for dislodging the` lime and causing it to drop into the hopper, as hereinafter described.
The outer wall A of the kiln is formed of stone and is made six-sided. The inner wall B of the kiln is formed ot' lire brick, and is made round., The arches O are also lined with fire-brick, and should be one in each side in large kilns, and one in every other side in small kilns.
Upon each corner of the outer kiln is placed a hard-wood timber, D, the inner sides of which are grooved to t upon said corners. To the upright timbers D are attached hard- Wood planks E, forming a casing, which may be strengthened by one or more bands or hoops, F. The space between the casing E and the outer Wall A is tamped with clay.
This construction makes the kiln air'tight, even should it crack.
G is the draw-hopper, which is made of cast-iron, and nearly one-half of which is exposed to the air, so that the lime, before it is drawn, may become partially cooled, and may .thus be conveniently drawn and handled.
The hopper G is provided with an inclined bottom, g1, anda door, g2. H is aV rod placed just above the top of the door g2, and the inner end of which is pivoted and swiveled to the back wall ot' the said hopper G.
The outer end ot the rod H passes out through a hole in'the plate I, and through a horizontal, slot in the front wall ofthe hopper G, and has a crank, J, attached to it, to serve as a handle to 'rotate and vibrate thel said rod H. The plate I slides in keepers attached to the wall of the hopper G, as the rod'H is vibrated. To the middle part ot' the rod His attached one or more crossrods, h', which, as the rod H is rotated or vibrated, catch upon and dislodge the lime, so that it can be drawn. The two movements of the rod H enable the lime to be dislodged and drawn most effectually. The rod H also enables the drawing to be stopped whenever desired.
p Having thus described our invention, we claim as new and -desire to secure by Letters Patent- 1. In combination with the wall or stack-A B of the kiln, the casing D E and the filling of clay, as and for the purpose speciiied.
2. The combination ol' the rotating and vibrating rod H, provided with one or more cross-bars, h', and the sliding plate I, with the castiron draw-hopper G of the kiln A B C, substantially as herein shown and described.
