1 claim. (ci. zzz-f1) This invention appertains to new and useful improvements in brick lining for kilns and similar apparatus. .n v l The principal object `of this invention is to provide a kilnvlining, wherein certain of the lining bricks project to engage and lift the material under treatment as it rotates.

Another important object of the invention is to provide a lining for rotary kilns wherein bricks of the lining project inwardly to catch material and lift the same, instead of permitting the material to remain in the bottom of the kiln asnow occurs. v A

During the course ofthe following vspec'ication andclaim, other importantobjects and advantages of the invention will become apparent to the reader.

In the drawingszs Figure 1 represents an end elevational view of thelining. i y e Fig. 2 represents a fragmentary vertical sec-p tional view through the shell of a kiln showing the lining therein. v

Fig. 3 represents a perspectiveview of one vof the protruding fire bricks; Y c

. Fig. `4 represents a vvertical Vsectional -view through one of the projecting fire bricks.

Referring to the drawings wherein like numer-v als designate like parts, it can be seen that numeral 5 represents the outer shell of a rotary type of kiln. Numeral 6 represents the brick of the usual e kiln lining, whereas numeral '7 generally refers to the novel brick making up the present invention.

brick consists of a rectangular portion Ai having a ared enlarged head portion y9a1ong one longitudinal edge thereof. This head tapers inwardly in the manner shown in Fig. 3 so as to engage between adjacent bricksv 6` of the kiln lining in the manner substantially shown in Fig. 1.

In the manufacture of this novel brick 7, a plurality of elongated members 10, each provided with a plurality of spurs or anchor members 11 are molded in the brick, having the heads 12 thereof exposed at the inner end of the brick, While the protruding remaining ends of the members 41() are threaded as at' 13 and extend through openings in thekiln shell 5. Nuts 14 are engagel able on these threaded extensions 13 for firmly, securing the bricks to the innerlsides of the shell 5 and between' thev bricks 6 of the lining in the manner substantially shown in Fig. 1. i It can be seen Fig. 1,'that the` flared enlarged edge portion vci the brick 7 is the portion which fits between the bricks Vof the lining and it can also be seen, that with the members 10, which lare of* metal, disposed entirely through the brick 7, the brick will be reinforced and cans not break` oil at the lining.` i,

While the foregoing specification sets forth the invention inV specific terms, it is to be under# stood that numerous ,changes in the speciiic shape, size 'and materials may, bel resortedto withoutdeparting from the spirit and scope of' the invention as claimed hereinafter.

Having thus described myinvention, what IV claim as new ist- Y,

In a kiln, a shell, a brick lining for. rthe shell, a plurality` of relatively-wide bricks, saidv wide bricks beinginterposed between the bricks of the lining so as' to project ,inwardly of thekiln be-l e yond the lining bricks, means for securing the `wider bricks to the shell, said wide bricks each` being provided with `a transversely extending reinforcingmember protruding ,beyond the block and its outermost side, said `shell being provided with an opening therein, said projecting portion `of the reinforcing element being disposed through theopening of the shell,andsecuring means on the reinforcing element at the outside of thel v. 80 RICHARD W.
