APPARATUS FOR BURNING BRICKS.

Application filed January 4', 1923.

To all wit-0m "J2 may concern:

Be it known that I, IVILLIAM W. DICKIN- soN, J12, a citizen of the United States, residing at Little Rock, in the county of Pulaski and State of Arkansas, have invented a certain new and useful Improvement in Apparatus for Burning Bricks, of

which the following is a full, clear. and

carrying device therefor so designed rela tively to each other that the one will brace and support the other during transportation, the scoving also conforming to the requirements of the kiln structure; while further objects and advantages of the invention will become apparent as the description proceeds. This invention is an improvement upon that described and claimed in my Patent No. 1,403,300 issued January 10, 1922, and its general nature will be understood by reference to the accompanying drawings in which I have illustrated somewhat diagrammatically certain physical embodiments of the same. Fig. 1 is a perspective view of a portion of a row of kilns constructed in accordance with my invention; Fig. 2 is a face View of a portion of one of the lifting frames together with a section or panel of the scoving; Fig. 3 is a sectional View cor responding to the line 3-3 of Fig. 2 and looking in the direction of the arrows; Fig. 4 is an edge view of the carrying frame unloaded; and Fig. 5 is a perspective view of one of the supporting fingers.

So far as my invention itself is concerned 1t 15 immaterial whether each kiln 1s independent of all others or whether they ad- Serial No. 610,598.

of the row or even a common derrick. The only essential requirement is that the scoving be applied bodily after the body of the kiln is built, held securely and tightly in place while it is being burned, and be then bodily removed to enable rapid cooling and ready demolition.

In the embodiment here shown 11 represent the rails and 2 the traveling frame of an overhead crane, 3 being the carriage and d the hoisting drum from which depends the cable 5. Beneath this crane is a row of kilns represented generally at A, B, C, D, and E, of which A is being demolished, B is cooling, 0 is burning, D is drying, and E is being built. The bricks in the interior of the kiln are laid in the usual manner so as to permit the rapid and uniform penetration of the heated gases to every part thereof, this work being done either manually or mechanically, suitable arch ways or eyes FF being left for the reception of the fuel or the introduction and distribution of the heated gases. The outer walls of the kiln are given an inclination or batter indicated at G which preferably varies at different points as shown in Fig. 3, between top and bottom, producing a generally sloping outer surface which may either define a somewhat regular curve from top to bottom as indicated in Fig. 1 or a comparatively abruot elbow at some point between the top and bottom as indicated at H in Fig. 3. This inclination or batter has the double function of increasing the stability of the kiln and of cooperating with my improved scoving in a way I will now describe.

This improved scoving consists of a plurality of sections or panels made of any suitable refractory material such as fire brick, suitably held together and comformingsubstantially to the exterior shape of the kiln. Certain mode s of manufacturing this scoving are set forth in my prior patent N 0. 1,403,300. For purposes of the present case it is sutlicient to state that it is best made of fire brick, either tongued or grooved together or furnished with metal dowel pins; the scoving may sometimes be laid up without this precaution but in any event it is best to cement the bricks together by some sort of ceramic cement which will harden under the heat of the kiln; and in addition to which these panels may be painted or coated from time to time upon the inner and outer surface with a suitable glazing r finishing material which shall. assist them to withstand the heat of the burning and the strains of transportation.

In the construction of these panels, the side walls of the kilns are first built to the required curvature, either by the use of a suitable template or by the experience of the workmen which soon enables them to dispense with templates. Spaced supporting bricks 7-'T are then laid along the side of the kiln and on these are built the various panels (i(i, which are originally laid up one brick at a time so as to follow approximately the slope or the kiln and produce what may be looked upon as a kind of rampant arch. Complementary rabbets 8-8 are formed at the vertical edges of these panels, and holes 9 are tormed so as to register with the diti'erent eyes or arches. Preferably the width of each panel is equal to the distance between adjacent eyes so that each panel is made with a central hole 9, thereby rendering all the panels mutually interchangeable. As soon as the kiln has been burned the first time, the heat thereof welds each panel into a single rigid plate.

For transporting these panels I provide a frame one type of which is shown diagrammatically in Fig. 1 and with more detail in the remaining views. This frame comprises a plurality of upright metal bars 1010 conforming in shape to the exterior of the panels and braced by suitable horizontal members 11, 12 and 18. In the present embodiment the member 11 consists of a horizontal rod at the lower end, the member 12 a plurality of horizontal plates riveted be tween various bars adjacent their upper ends and the member 13 a similar series of plates riveted between these bars a short distance above the rod 11. :Pivoted upon the rod 11 between each pair of bars are a pairoi rightangular members comprising a carrying linger 15 having a seating portion 16 adapt ed to engage the lowermost brick of: the panel, and a shank portion 17 adapted to engage the member 13. Each of these members is .formed at the junction of the portions 15 and 17 with an aperture 18, through which passes the rod 11. rangement permits such of these devices as are not necessary, to be rotated back out of the way as shown in Fig. at. Besides these members are preferably slidable freely along the rod 11 so as to avoid the blocks 'T-7 in case there should be any inadvertence in the spacing of the same under different panels.

Pivoted to the uppermost end of each of the bars 10 is a lever 20 whose outer ends are connected by av suitable cross-piece '21 and whose inner ends are connected by a second cross-piece 22 to which is fastened a wooden pressure block 28. Hinged to the The pivotal arcross-piece 21 is a suitable equalizer 24 to which in turn is attached a suspension hook 25 carried by the cable 5.

In use this frame is applied to the panel which is to be moved, the lingers in being adjusted as necessary to tit between the blocks 77, the bars 20 conforming closely to the exterior of the panel, and the block 23 fitting over the upper edge of the same In order to bring the arm 20 substantially horizontal it is sometimes necessary to interpose suitable tillers 26 such as old timber:- or pieces of scantling. If new the cable I- be elevated, the inner ends of the lever: 20 will tend to pinch the panel against the lingers 15 while its crowning shape presses it against the face of the bars ant causes it to be held with great security, while it is transferred from point to point by the crane still possessing its rampant position. To facilitate the moving of the empty frame, a pair of rods 27-27 are articulated to the cross-piece 21 and the eyes 28 at their lower ends adapted to be applied to hooks 29 on the bars as shown in Fig. 1, thereby holding the levers 20 in horizontal position ready tor instant application to any desired panel.

In case any panel becomes accidentally broken or disintegrated, a new one is built as at first, wherever convenience may indicate, and after the first burning becomes fused into a unitary mass. T he joints of the panels can be stopped by means of clay, mud, sand, etc., as will be understood by all brick-makers; the inside of the panel may be shimmed away from the wall of the kiln in case it shoul become warped so as not to fit the same or in case the workmen should mistake the batter to be provided; and likewise the exterior of the panel can be shimmed away from the frame in case of warping or mistake in manufacture. Also I do not restrict the use of my invention to the side walls of the kiln for it is obvious that it can equally be up )lied to the end walls or the top walls merely by varying the angles. Accordingly I limit myself in no way except as recited in the annexed claims.

Having thus described my invention what I claim is:

1. A kiln scoving consisting of rigid rectangular independently movable anels of non-metallic heatresisting materia supported in upright position upon the exterior of the kiln, each of said panels bowed out wardly between its upper and lower ends and the body of the kiln being sloped to conform approximately therewith.

2. Apparatus for burning bricks including a kiln covering made of rectangular panels of non-metallic heat-resisting material, set in upright position about the kiln, each panel being bowed outwardly between its upper and lower ends, and means for ti l transporting said panels bodily from one place on the kiln to another.

3. Apparatus for burning bricksincluding a kiln covering made of outwardly bowed rectangular panels of non-metallic heat-resisting material, and a carrying frame therefor having a part adapted to engage the exterior of a panel in tracing relation and other parts adapted to engage the margins of the panel in compressing relation. a

4. Apparatus for burning bricks including a kiln covering made of rectangular panels of non-metallic heat-resisting materiahbowed lengthwise and having their convex sides outward, said panels being lo cated in upright position about the side walls of said kiln 5. A kiln scoving consisting of independent rigid rectangular panels curved in the direction of their length and mounted in rampant position upon the sides of the kiln body, and means for transporting said panels in rampant position including a rigid frame adapted to engage the convex sides of said panels, and members carried by said frame adapted to engage and press inwardly upon the end margin of said panels.

6. The combination with a portable sec tional kiln scoving consisting of rectangular panels of non-metallic heat-resisting material, constituting rampant arches, ofi a carrying frame for said panels comprising a part adapted to engage the crowns of the arches in bracing relation and other parts adapted to engage the springers of the arches in squeezin relation.

In testimony whereof, I hereunto afiix my signature.
