SAUL W. SHOOP, OF FRONT ROYAL, VIRGINIA.
LIMEKILN.
SPECIFICATION forming part of Letters Patent N 0. 745,248, dated November 24, 1903.
Application filed January 28, 1903. Serial No. 140,837. (No model.)
To all whom it may concern:
Be it. known that I, SAUL W. SHOOP, a citizen of the United States, residing at Front Royal, in the county of Warren and State of Virginia, have invented certain new and useful Improvements in Limekilns, of which the following is a specification. V
In the ordinary construction of limekilns the expansion caused by the great heat is ordinarily more rapid in the tie-rods employed to tie the walls together than in the walls themselves, which results in relieving said walls of the support of said rods and permitting them to crack. The life of the kiln is thus Very much shortened.
My said invention consists in a peculiar construction of limekilns, particularly in the form of the kiln whereby the expansion and contraction of the walls thereof will be as great as that of the tie-rods used for tying them together, thus maintaining the strain of said rods at all times, as will be hereinafter more fully described and claimed.
Referring to the accompanying drawings, which are made a part hereof, and on which similar reference characters indicate similar parts, Figure 1 is a perspective view of a kiln constructed in accordance with my invention; Fig. 2, a central vertical section through the same; Fig.3, a top or plan view; Fig. 4, an outside plan View of the door of the furnace; Fig. 5, a transverse section through the same; and Fig. 6 a view of the outside of said door in perspective.
In said drawings the portion marked A represents the walls of the kiln, and B the door of the furnace. Said kiln is'constructed of masonry and except for the form thereof is or may be of any usual or improved construction. Each of its sides is formed inclined inwardly from its outer corners to its center, as shown niost clearly in Fig. 3. Corner posts or irons A are arranged on each side of the several corners, and tie-rods (I. extend through said posts and from one side of the kiln to the other, binding the walls securely together.
In use, when the heat begins to expand or contract the kiln or its furnace the expansion or contraction of the masonry-wall,on account of its breadth being sufficiently greater than the length of the tie-rods, will be equal to the expansion of said tie-rods and the strain upon said rods will thus be maintained, thus permitting them at all times to perform their function of holding said walls together and prevent their cracking or checking, as is cominon with the construction in general use. A very much more durable kiln is thus provided. Another difficulty commonly experienced in the useof limekilns is the warping of the furnace and ash-pitrdoors. In order to obviate this difficulty, I have formed a door of peculiar construction, the inner'face being bounded bya wide fiangeb,which is filled with fire-brick liningb to protect the metal from the heat. also surrounded by a flange 17 near its edges, and with several vertical flanges b extending from the top to the bottom thereof. The
flanges are preferably tapered, being wider' at the bottom than at the top, as shown. The construction not only protects the metal from the heat, but enables the door to maintain its perfect form withstanding the action of the heat, which ordinarily causes it to warp and twist out of shape, so that it cannot perform its function perfectly.
It will be understood that the form of the kiln may be varied from that shown without departing from my said invention, which consists, broadly, in making its walls or the walls of the furnace portion longer in cross-section than the tie-rods, so that they may expand or contract from corner'to corner as rapidly as said tie-rods also that the peculiar form may be confined to the lower section or furnace, where the heat is greatest, if preferred.
Having thus described mysaid invention, what I claim as new, and desire to secure by Letters Patent, is
