To all whom it may concern:

Be it known that 1, WILLIAM DRAY'roN, a citizen of the United States, and a resident of Shawnee, in the county of Perry and.v

State of Ohio, have invented anew and Improved Kiln, of which the following is a full, clear, and exact description.

Among the principal objects which the present invention has in view are: to provide a kiln having a tunnel-like structure, constructed and arranged to convey material being handled through the said kiln by stations; to provide a plurality of platforms portably arranged to carry the material being handled; to provide a system of seals to prevent the admission of heat to the metal frame and rotating parts of the above mentioned platforms; to provide a plurality of portable partitions arranged in conjunction with the above mentioned platforms to confine the heat within certain areas; to provide a heat circulating and transfer system whereby the heat units are utilized to the greatest advantage; to provide an air circulating system for the kiln whereby is prevented the pocketing of air; to provide a burning system employing producer gas fuel and means for mixing burned atmospheric air; and to provide portable platforms having a structure adapted to resist heat of a degree hiher than that required for the burning of the material being handled.

One embodiment of the present invention is disclosed in the structure illustrated in the accompanying drawings,.in which like characters of reference denote corresponding parts in all the views, and in whicl Figure 1 is a fragmentary view in horizontal section, showing the arrangement of a portion of a kiln constructed and arranged in accordance with the present invention; Fig. l is a fragmentary view' on similar plane, forming a portion of the general plan of the kiln in conjunction with that shown in Fig. 1; Fig. 1 is a continuance of the view shown in Fig. 1*; Fig. 1- is' a continuance of the view shown in Fig. 1; Fig. 2 is a longitudinal vertical section of a station formed in the kiln; Fig. 3 is a detail view, on an enlarged scale and'in horizontal section, taken on the line 33 in Fig. 2, showing the construction and arrangement of one of the portable platforms; Fig. 4 is a vertical cross section, taken on the line l -46; F A- 4 l; in Figs. 1, l, and l", showing the arrangement of the supporting platform and Specification oi-Letters Patent.

the tunnel kiln in conjunction with a gas producer plant and delivery duct therefor; Fig. 5 is a detail view, on an enlarged scale, taken on the line 55 in Fig. 1, showing the construction and arrangement of one of the portable partitions and the filling members therefor used in conjunction with the tunnel; Fig. (3 is a detail view, on an enlarged scale and in verticalfisection, showing the construction and arrangement of a sand seal for preventing the leakage of air from the delivery ducts; Fig. 7 is a detail view, in vertical section and on an enlarged scale, of the sand seal interposed between platforms to prevent the leakage of heated air to the structural members of the platforms below the floor thereof; and Fig. 8 is a detail view, on an enlarged scale and in vertical section, of the heated air seal disposed in the tunnel sides to prevent the leakage of heated air from the burning chamber of the tunnel.

The tunnel as formed according to the present invention is illustrated in Figs. 1, l, 1, and 1; the said figures are to be read together. In practice the tunnel is stretched out to form one continuous passage, preferably in straight extension, although this is not a necessary condition, as results more or less advantageous may be obtained by forming the tunnel in a circle or in the form of a plurality of parallel extensions suitably connected, with the means for transferring the portable platforms or trucks at the connect ing ends of the alleys. When constructed in the straight line extension the preferred arrangement is. that shown, wherein a producer gas furnace 13 is directly connected to deliver its fuel in the section marked l). The furnace 13 is of any approved construe lion and arrangement, and is provided with a delivery outlet 14, which is connected with a lateral drum 15. The drum 15 is connccted at both ends thereof to delivery ducts 16, 16. The delivery ducts 16, 16 open into vertical passages 17, which are extended up ward above the floor 18 of the tunnel. The vertical passages 17, may be circular in form and surrounded by a circular upturned channel 19. The channel 19 is of sufficient depth to contain sand, or other suitable packing material, which is adapted to prevent the passage of heated air therethrough. The tunnel 20 is shaped in cross section substantially as shown in Fig. 4 of the drawings, having an inner masonry wall 21 and buttress walls 22, 22.

Between the wall 21 and the wa ls 22, 22 is disposed a. suitable tilting material a apted to prevent the radiation of heat therethrough- Disposed in the tunnel 20 and lengthwise thereof, are metal trael-rs 2t 24. The tracks 24, 2t are mounted upon inundation piers 25, extended lengthwise of the tunnel. The tracks 2-1, 2% are provided to support carrying wheels 26, Q6 The carrying wheels 26, fit} support the portable t ucks forming the sectional liners of the burning chambers of the kiln. The lloors are supported on steel beams 27, 21' disoosed transversely of the tunnel and traelts 24, 24'. The

; beams 27 are su 'iported by double longitudi I-heams "l, 28, which are rested upon bearing boxes 29, 25). The bearing boxes 29, 29 provide bearings for the journals of the shafts with which the wheels 26, 26 are prosided. The steel beams 21', 27 are provided with an'upward and outward extension 30, at the outer ends whereof are mounted longitudinally disposed side plates 31. The side plates 31 are provided at the lower ends with inverted V-shaped channels 32, 32. The channels 32, 32' are slidahly extended within utters 233, 32.) fixedly mount il on the side wall of the tunnel 2 and extel'uiled lengtlm'ise and throughout the same. When the gutters 33, 5323 are filled with sand or other s aling material to PLQVQDl/ihfii passa e of healed air, as shown suhstaiitially in Fig. i of the drawings, and the V-shaped channels 32 are extended into the said sand, the heat which is introduced into the tunnel 20 above the floor of the said trucks is prorented from passing from the upper porti n of the tunnel to the lower portion thereoi wh rein are (lit-spew the tracks ill and the u leturalhotly and wheels for the trucks, as above described. it is to prevent any radiation of the heat; from the sand contained within the gutters 5513, that there are provided the gates 34, which exclude the relatively eool air of the lower part of the uunel from contact with the surface of the sand 3 placed in the said gutters 33. The \Lshaped channels 32, 32 are exposed on their upper surfaces the air. In this manner over-lieating oil the metal eomposlog the rhannehe is prevented. It will he ooserred that he air will circulate in'the ehannels so formed to the ver bottom tlfet'eoh l.- l'ralniue; structures of the trucks are oi, as shown particularly in llu lraw n 's. \Vhore the 1rd their-1 rse lu-alns '27, i-t t e t-zuls ol the irurus are with dept-ruled flanges ill l :l to extend within the me al within an upwan'lly ogwir 'l'ho li-or 3% is extended from tunnel and thus prexents 1 'l'illlill between the lee:

cross section in Figs. 4 and 5 of the draw ings. The material thus provided and supported by the trucks constitute the bed of the hurning chamber of the kiln The llCtl 39 of the kiln is provided with a series of duets 40, 40 extended lengthwise of the bed and opening outwardly into the burning 'ehamhers formed in the said tunnel. Ali-'3 bed on each truck is provided with a eirerlar depended funnel 41, adapted to register with the assage 17 used for delivery of the gas fuel Irom the producer 1 5. The tunnel 41 has mounted thereon an annular ring t), the depended edge whereof is adapted to extend into the sand ehannel lfl to form a seal therein. The ring 12 is vertically disposed to permit the same to be raised out of and lowered into the channel 19, when in the course of operation the successive trucks are moved into alineinent, with the passages 17. The passages 17, 17,'it will be understood, are disposed only in the section of the tunnel marked D and opposite the gas produ 'er furnace 13. It will be under end that in the operation of this ltilu the preheated air which is delivered through the ducts -3 and 54; to the duets 40, 40 ignite the gas delivered from the producer through the ducts p rtable see-lions thus become the kiln t'ur naoe. The bed 39 prorillml with any suitable nuniher of spaces 43, 4: 3 to lighten the construction. The bed is also jirorided with a series of longitudinally extended flat pas sages 4'4, 44 for promoting; the circulation of the relatively cooler air of the tunnel below the bed 39 to reduce the trm 'ieraturn ol" the said bed adjarent to the steel beams 27, ii and. A portion of the air delivered through the passages ll is earried into the chamber to assist the combustion within and through the hrirhs pile l. upon the said l tll- The lltllfi ill), 3!) are provided with lateral upwardly extended side flanges 45, The flanges 41), 45 are provided to guide any bricks or parts thereof which may tall From the stark resting upon the said beds as arranged thereon for burning.

The hri ll's are star-ha l in any ap: proved manner, the ohjret lie. o provide a rirrulaliou thr ug'lmu the IHOIHlKEI'S in the stark. The trurlts having the bed 39 may be. united in rouplrs orin at its oi more than two, urrord. as the shortened.

section I) of the tunnel be elongated or With reference to the formation of these sections the partition trucks are disposed. :The partition trucks are arranged to separate the brick carrying trucks and to form partitions to aline with the walls of the tunnel to form longitudinal separated chambers therein. 7

The partition trucks are mounted on wheels 46, 46 similar in all respects to the wheels 26,.26 on the brick carrying trucks. The framing structure of the trucks is similar. The principal difference in the trucks is in the formation of the chamber 47 raised above the bed of the truck. The chamber 47 is box-like in form, having a solid top 48 and solid sides 49, 49. The end walls of the chamber 47 110 pierced to form openings 50, 50 The openings 50, 50 permit the air from one chamber to pass into the chamber 47. (See Fig. 2 of the drawings.)

Depended from the bed of the partition trucks is a funnel 51. The tunnel 51 in each truck is adapted to register with the passages 52. The passages 52 deliver downward into a longitudinal passage 53. The passage 53 is provided with distributing passages 54, 54. The distributing passages 54, 54 deliver the air from the passage into the chamber succeeding each of the partition trucks, the air being distributed hav; ing been delivered through the partition trucks to the said passage 53. The delivery of the air througlrthe passages 54, 54 is controlled by a slide gate 55disposed at the treme of each of the passages 54. The passages 5-1 are raised above the floor 18 of each chamber to register with a funnel 56 carried on each of the brick bearing trucks. The funnel 56 opens into the ducts 40. 40 in the bed 39, the air delivered from the said funnel 56 mixing with the gas delivered from the funnel 41. The air thus dolivered,.it will be remembered, isair which is received from the chamber in which the material which has been burned is cooling, thereby reusing the heated air given oil in the cooling radiation'for maintaining the ten'ipcrature in the burning chamber or section I). From each of the sections the heated air is delivered through the funnel 51 in each of the partition trucks to the next succeeding section or chamber, aiding in raising the heating temperature in the said chamber. In this manner the heat produced by the gases from the burner 13 is carried successively backward from the section E to the chamber D and thence to sections C, B and A. The mixed air and gases are finally drawn through the tunnel by an exhaust fan 58. To maintain the circulattion of air a forcing fan 57 .is provided at the opposite or delivery end of the tunnel to deliver through'a duct 59 to the passage 53.

It is desired to dry the bricks as the same prtliminary to the same entering the burning chamber. For this purpose the passage 53 disposed at the receiving end of the tunnel and under the initial or receiving station therein, being the section A shown in the drawings at Fig. l, is connected by means of the passages 60, 61, 62. and (53 with the cooling station or section E shown in the drawings at Fig. l". The heat radiated from the cooling bricks delivered from the station D is mixed with the air introduced through the passages 57, 37 from the fan 57 and is delivered to section A at the entrance end of the tunnel through the passages 63, 62, 61, 0 and 5?), and the funnels 56, 5G in the floor of the said section. The heat thus delivered from the bricks leaving the tunnel is utilized for preliminarily heating the bricks being introduced into the tunnel. The heated air and vapor drawn from the green bricks is drawn oil by means of the fan 58 through the duct 59 and chamber 47.

It will be understood that the entire circulation of air is from the delivery end of the tunnel to the receiving end, this circulation being helped out and partially induced by the fan 57 at the one end and the Fan 58 at the other. The air radiated from the material being treated while in the sections adjacent to the delivery end of the kiln, is carried back aml delivered into the burning chamber or section D. From the burning chamber or section I) it. is delivered through the chamber 47 of the partition trucks to the next succeeding chamber. and so on, being delivered from each chamber to the next succeeding chamber until delivered to the exhaust fan 59. At each succes h step, as it passes from section to section. it aids in the heating of the brick carried by the trucks and stacked upon the beds 39, 39. By means of the slide gates 55, 55 any section may be cut out or the delivery thereto controlled.

The partition trucks are constructed to freely pass through the tunnel 20. The outer walls of the truck bodies are square and arranged substantially as shown in Fig. 5 of the drawings. the top 48 are squared to r ceive in batted relation the baflle plates 64, 64 and 65. The buttress walls 22, 22 are parted to form recesses 66, 6G to operate the baflies (34. 64, while the baflie 65 extends above the filling The side walls 49 and.
