, My present invention relates to scoving,

and more particularly to an improved form pi portable scoving for brick kilns and the 5 As is well known, in a brick kiln it is necessary to 'rotect the sides of the kiln by a scoving w ich. may be either built onto the sides of the kiln or a portable scoving used, the idea being to economize fuel and obtain a more even heat during the burning process. What may be called permanent scoving is expensive to manufacture and results in a great many" ruined brick} because of the material of the scoving adhering to the same during the burning process, Portable scoving'as at present utilized is also unsatisfactory because of the difficulties of handling the same and the liability-to breakage a n warping because of the intense heat to which it is subjected and no satisfactory means has heretofore been devised for obviating the results of cracking or warping. Further, in portable scoving as at present utilized, there is no satisfactory way of insertin thereln the usual and commercial form of 'ln door. i In my present invention, I have obviated the objections to portable scoving as here- 1 ,tofore made and have provided a novel form of'port'able scoving which maybe easily and readily handled by the ordinary conveyor mechanism found in af-brick kiln and in which any cracking due to expansion, contraction, or handling of thematerial can be taken up. Further, in my new and improved form of scoving the usual and c'o rnmercial type of kiln doors may-be bullt 1n and when so built in,"form a part of the scoving itself and may be handledwlthsuch scoving. Also, by my improved mventionI am enabled to hold a section or sect ons of scoving in an upright 'pos1tion while the kiln is being emptied, and in 'a redetermined slope while the kilnis being lled and thereafter releasing the scoving so thatthe brick in, place and close up the space occasioned by the shrinking of the brlck during the process of burning.-

In carrying out myimproved invention I arrange channel'irons 1 at the top and bottom of the scoving which is built up from insulatin and fire-resisting material and arrange a pluralit of rods that run entirely" through the insu sting and fire-resisting ma -weight of the scoving will act to hold the te-rial' and such rods co-operate with the channel irons at the top and bottom of the sections of scoving whereby the rods, when placed under tension, will take up any cracking caused by the expansion and conerly in theforks itwas necessary to have it so hung thatxthe slab was lying at an angle in the forks. This necessity for inclining the slab of scoving'rendered it impossible toaccurately position the slab with respect to the kiln and also rendered necessary a considerable amount of room between the stacks of bricks and the posts of the kiln building. I have obviated this objection in my "present structure and have provided.

ineanssecured to the top of the slab of scovmg, such means being adapted for attachment to the crane hooks. I am enabled,'by

this improved structure, to manipulate the scoving. in the minimum amount of room which is of material advantage in allowing "the fullest use of the kiln building'in building the kiln. By this method of handling the scoving I am also enabled to fix the slope of the scoving with respect'to the yet unbuilt kiln, the s10 e given to the scoving governingthe settling of the brick inthe kiln, and after the kiln is built, I utilize means associated with thescoving so that such scoving will, follow the brick during the process of burning the same and prevent the openings which would otherwise occur.

The principal object of my invention, therefore, is an'improved and novel form of portable scoving for brick kilns and the like.

Another object of my invention is a' portable scoving section'having as an integral part thereof and inset therein the commercial 1: pc of kiln door.

cracking due to expansion and contraction or handling or warping of the scovin sec tion.

In the aaeompaayin drawingsilliistr'at beams 17.

ing a preferredembodiment of my'inve'ntion as located in a kiln,

Fig. 1 is a sectional elevation through a shedshowing'a kiln in elevation and with my improved scoving in position with respect to such kiln, and

Fig. 2 is a side elevation of Fig. 1 's'howing in front elevation a section of scoving havi'ng jos'itioned 'as'an integral part there of the commercial type of kiln.

Referring to the drawings, the shed is constructed in the usual 'manner of a plurality of uprights 1Q spaced apart from each other and tied together at their top by tie rods or beams 11, a roof 12 being built at the upper end of the uprights 10. At any conv'enient'height above the ground level and attached to the uprights 10 are supports 13 on the'upper end of which rest and are secured eye "beams 14 running parallel to the length of the shed as is usuah Secured to the top of'the beams 14 are rails 15 arranged parallel to each other and constituting tracks on which run wheels 16 rotatably. mounted on, and supporting, the traveling crane Means are provided, as'indicated by the numeral 18, for causing a rotary movement of the wheels 16 and'therefore a movement of the crane beams 17 along the length of the building while a traveling carriage 19 is arranged with suitable means whereby an operator may controlthe crane mechanism. The above structure with regard to the crane is the usual structure and is well understood and a detailed description thereof appears to be unnecessary. Between theground level and thesupporting'beams '13 and secured to the uprights 10 are beams 20 provided at intervals with hooks 21 that extendinwardly towardthe interior of the shed for a purpose to be hereinafter described.

As is usual, the kiln is built up of a plu-.

rality of stacks of bricks 22 arr'angedin' hacked relation in the usual manner, the

kiln occupying the major portion of the floor space of the kiln, but leaving along each side wall, as defined by the posts 10, a passage for the workmen. In place of the usual scoving I arrange sections of portable scoving, said sections being constructed "by placing the channel iron -23-'at.the bottom and a channel iron 24 at the top arranged (not shown) in the ch'a'nneli'r'on 24 and the extended ends of such rods 26 are'threaded to receive nuts 27 and by means of which the channel. irons 23 and'24 are forced firmly intoengagement with the top and bottom ends of the slab 25. As shown in Fig. 2, I have'arranged three rods 26 in the slab 25, but the number maybe varied as desired "without departing fro mthespirit of the invention. Secured to the top channel mem ber are eyes 28 and the number of such eyes may 'be any number desired, though I have found "two tobe ample. Secured to each of the eyes 28 is one end of a chain 29, which chain may be attached to the hooks 21, above referred to, and whieh chain, as will be seen from an inspectiondf Fig. 1, prevents atoo far inward movement of the upperend of the s ec'tion of'scoving toward the kiln.

IVhere the section of scoving is to be "located around the kilnat a point where it is,

desired to, fire the kiln','kiln doors 30 are arranged on the lo w'er channel iron 23 and the slab of material 25 is molded around the same, thus securely fastening them in position.

In utilizing my improved sections of scoving, the kiln is built in the usual manner andfthe crane operatoiyby manipulating the crane, hooks onto the eyes 28 and transports the sections of scoving to any desired position around the kiln, as shown, for example,

in .the drawings, and, assuming it to be the ordinary section of scoving, it isplaced with relation to the kiln with the channel iron 23 closely adjacent to the bottom of the stack or unit 20 and inward movement of the upper endof the section of scoving 'is predetermined and limited by the use of the chain 29 in connection with the books 21.

The kiln is nowbuilt up in the usual manner of'a, plurality of stacks or units and,

when thekiln is completely built, it is entirely surrounded by the sections of scoving.

V The chains 29 may nowbe released from the hooks 21 so that the weight of the sections of scoving rests on the kiln and the tops of such sections of scoving will move inward toward the center ofthe kiln as the bricks forming the stacks or units 22 shrink during theburning operation. After the brick have been entirely burned, the tops of the sections of scoving maybe moved toward the line of posts 10 and held thereagainst by meansof the chains 29 and hook 21 or may be moved to anyportion of the shed desired by the use of the traveling crane. 7

While I- have necessarily shown, and described the preferred embodiment of my invention somewhat in detail, it is to be under- I stood that I may varyv the size, shape, and

arrangement of parts within wide limits without departing from the spirit of theinvention.

Having thus described my invention, what I claim as new is:

1. An improved portable scoving comprising a slab of insulating and fire-resisting material of suitable thickness and means for placing the material of the slab under compression. V

2. An improved portable scoving for brick kilns and the like comprising a slab of insulating and fire-resisting material, a metallic member arranged at each end thereof, tie rods extending through the slab of material and metallic members, and means associated with said tie rods for forcing the metallic members toward each other whereby the slab of material between such metallic membersis compressed and any cracks appearing in the slab from contraction and expansion or handling are taken up.

i 3. An improved portable scoving comprising a. slab of insulating and fire-resisting material, channel irons arranged atthe top and'b'ottom of such slab of material, a kiln door resting on the 'bottom'channel iron and fitting into and through the slab of insulating or fire-resisting material, a plurality of tie rods extendin through the slab of materiaL'and means or placing said rods under tension whereby the channel irons are forced toward each other to thereby compress the material of the slab to take up cracks in the material. 1 4. That improved method of utilizing portable scovin in connection with the building of kilns an the burning of the brick therein which consists in setting the portable scovmg at a predetermined slope to govern the setting of the brick in the kiln, securing such scoving in such predetermined position during the building of the kiln and then releasmg the scoving whereby such scoving will follow the brick during the process of burning to prevent openings in the kiln.

5. An improved portable scoving comprising'a slab of insulating and fire-resisting material of suitable thickness, means for. placing the material of the slab under compression, and operating rings secured to the top edge of such slab.

6. An improved portable scoving for brick kilns and the like, comprising a rectangular frame, bars extending longitudinally thereof, and a layer of fire-resisting material built into the rectangular frame and associated with said bars. I

7 An improved portable scoving for brick kilns and the like, comprisin an open rectangular frame, a plurality o parallelly arranged rods secured thereto, and a layer of fire-resisting and insulating material built into the open rectangular frame and sup.-

ported bythe parallelly arranged rods.

8. An lmproved portable scoving for brick kilns and the like comprising a reinforcement and a layer of fire resisting material consisting of a single integral slab.

In testimony whereof, I have signed my name to this specification. r
