Specification of Letters Patent;
Patented June 5, 1906.
Application filed June 7,1905. Serial No. 264,102.
To all whom it may concern:
Be it known that I, ALBERT P. BROOMELL, a citizen of the United States, and a resident of York, in the county of York and State of Pennsylvania, have invented certain new and useful Improvements in Kilns, of which the following is a specification.
My invention is an improvement in kilns; and it consists in certain novel constructions and combinations of parts hereinafter described and claimed.
Referring to the drawings, forming a part hereof, Figure 1 is a perspective view of my invention with parts broken away to show the interior construction, and Fig. 2 is a crossseotion on the line of the grate-bars.
In the practical application of my invention I provide a supporting-base A, preferably constructed of heavy steel plates, resting upon a substantial cast-iron base A of suitable width and thickness, the supportingbase being reinforced on the inside by Vertical posts a, formed from double angle-irons and bolted securely to the base.
Oppositelydisposed brackets B extend from the base, and resting upon the brackets and the upper edge of the supporting-base is a bed-plate C, V preferably constructed of heavy cast-iron. A cooling-cone D is bolted to the under face of the bed-plate and de pends therebeneath, being provided with draw-gates d, operated by wheels d, extending beyond the base. The draw-gates form no part of my present invention and are clearly shown and described in my former patent, No. 712,251, of October 28, 1902.
A steel shell E, constructed of steel plates bolted together, is secured to the upper face of the bed-plate in alinement with the supporting-base, and arranged upon either side of the shell are furnaces F, F, F, and F supported by the extended ends of the bedplate and communicating with the interior of the shell by means of the flues f, f f and f The furnaces are constructed of fire-brick and are arranged in pairs, the members of the pairs converging slightly toward their junction with the stack, and the diagonallyopposite furnaces being arranged on lines parallel with each otherthat is, a line drawn through the longitudinal center of the furnace F would be parallel with a line drawn through the longitudinal center of the furnace F The furnaces are approximately twentysufficient length to take in four-foot cordwood and are supported by buckstays f the buckstays at the front being extended at the top above the furnace and provided with pulleys f for supporting the firingdoors f The side buckstays are connected by tie-rods f across the furnace, and the front and central stays are connected by tierods f with the shell. The firing-door f comprises a frame f filled with fire-brick f and slides directly upon the fire-brick of the furnace, being attached to a rope f passing over the pulleys f and having attached to the free end thereof a weight f The grates f are made in two sections in order that renewals may be made at small expense. A cross-barf supports the sectionsiat the center and the rear end, and at the front they are supported by a dead plate f. A steampipe f is arranged beneath the grates and is .connected with a suitable source of supply for providing a forced draft.
The shell E is lined with brick over a part of its extent, and a heavy steel cone E is arranged above the brick lining. to prevent,
damage thereof by the falling rock. Above the cone is a storage-place E for rock. The kiln is of a height suflicient to prevent injury to the steel plates at the top by the heat from the furnace, while at the same time the rock in the storage-place absorbs a large amount of heat, the moisture being driven off, 'so that when the rock goes down to the burningpoint it is just ready for conversion into lime. A firing-platform G is arranged upon angleirons projecting from the brackets on the supporting-base and is constructed ordinarily of stringers, having a flooring laid thereon for supporting a paving of brickor concrete, as ma be desired, the stringers being extende a sufficient distance to either side of the kiln and supported by posts or other suitable means. By arranging the furnaces in the manner described I am able to cover a very large portion of the rock with the direct flames from the fuel, thus preventing the leaving of an unburned core of rock and increasing the output of lime. Each furnace being entirely separate can be fired without interfering with the others, thus admitting less cool air to the kiln and at the same time making it possible to suppl the kiln with arches that will not come own under the heaviest firing.
By arranging the firing-door to slide directly against the fire-brick no iron is exposed around the door, thus enabling the door to be renewed at a very small cost by simply inserting a new set of fire-brick.
It will be evident from the description that the peculiar arrangement of the furnaces with respect to the stack provides for the efficient utilization of all the heat and for the application thereof evenly throughout the" extent of the interior of the stack, thus securing a uniform burning of the rock and as a consequence a superior quality in the prod- Each of the furnaces being arranged upon a se'cant of the stack permits the application of heat to the rock near the outer part thereof, While the arrangement of the corresponding furnaces of the pairs symmetrically with respect to each other prevents the direct ap plication of the heat from all the furnaces on the rock in the center of the stack, thus avoiding overburning of the central portion of the rock. At the same time, however, enough heat is directed'upon the center to prevent the formation of an unburned core.
Having thus described my invention, what I claim as new, and desire to secure by Let ters Patent, is
to the flames that may creep out I supported on the base, and extending therebeyond, brackets secured to the base for supporting the extended ends of the bed-plate, a stack supported by the bed-plate in aliner ent with the base, a series of pairs of furnaces radiating therefrom, and discharging thereinto, the furnaces of each pair converging toward the stack and the diagonally op- *posite furnaces being arranged on lines approximately parallel with each other.

A kiln comprising a stack and pans of furnaces arranged on opposite sides of the stack, the furnaces of each pair divergin toward their outer ends, and the said en s of the furnaces terminating between parallel planes tangent to the sides of the stack at approximately a right angle to those from which the furnaces project, whereby the said ALBERT P. BROOMELL.
