In building up a wall with the presentblocks, the blocks are arranged in circular courses, and the blocks of each course are arranged end to *end; The blocks 1' lower course 10, as illustrated in Fig. 2, are preferably devoid of the portions 3, in order torest flatly upomnthe base or toundation; but-have the portions 2' which project upwardly. The blocks of the second course 1 are-inverted and staggered relative to the blocks 1 of the lower course 10, so that the key portions 2 of thebloc'ks'of'the course 11 dependv and fit snugly within-the recesses '5;5 between theupstanding portions 2 ot the blocks 1. Thus, the portions 3 of the blocks of the second course 11 project upwardly, and=the adjacent portions 3 of the respective blocks oft-he second course abut against each other, and provide key portions 8 projecting upwardly. The blocks of the-third course 12 are inverted and staggered relative to the blocks of the second course 11, and have their semi-key portions 3 projecting downwardly and abutting, similar' to the blocks of the second course. Thus, the depending portions 3 of the third course 12 fit within the upwardly disposed recesses t of the blocks of the second course ll while the upstanding portions 3 of the. blocks of the second course fit snugly Within the downwardly disposed recesses 4 of the blocks of the third course 12. The blocks of the fourth course 13 are disposed similar to the blocks of the second course 11, and having the upwardly disposed portions 2 of the blocks of the third course 12. In this manner. the alternateportions of blocks are inverted and staggered relative to the adjacent or intervening courses, the key portions of the blocks of the adjacent. courses interlocking or interengaging in a unique manner. It is of course understood that the wall may be constructed in arcuate or circular form, and to any height desired. The diameter of the structure depends upon the radius or curvature of the blocks, which may be altered in view of the various circumstances.

The blocks may be bound or bonded together by cement or mortar, in the usual manner, it being noted that the blocks are arranged in a break joint manner, which is desirable for obvious reasons. openings or recesses? are provided in the blocks, they not only lighten the weight of the blocks, but provide channels or passages within the wall, for the reason that theblocks when abutting endwise cause the recesses T of the adjacent ends of the blocks to match or mate each other,to register with the central oneningsti of the over and underlying blocks,

of the their lower portions 2 fitting between When the as will be obvious by "reference to Figs. 2 blocks are assembled in building a curved or and 3. In this manner, the wall. may be provided with vertical passages or channels, which is desirable inmany instances. 4

"Particular attention is directed to the fact that the blocks of the successive or super imposed courses being interlockdj-in thb manner above described, will enable the wall to resist outward pressure in a most efiectlve manner. Thus, thecoac'ting recesses'fi' of the blocks of the second course llrengaging over theportions 2-ott1hefhlocks-of the first or lower course :10, will. serve to lock the blockslof thBrSGCOIld course 11 against outward movement, inasmucha's the'portions 2 of the blocks of-the lowercourse 10 will tend to resist outward displacement of the blocks of the second course; Similarly, the blocks of the third course 12 having their recesses 4 engaged over the coiiperating portions 3--3 of the blocks of the second course, will lock the blocks of the thirdcourse 12 against outward movement, due to the tapered or Wedge form of the cooperating portions 3--3 and the recesses 4. In this manner, blocks of the successive courses are interlocked in such a manner as to enable the wall to effectively resist the outward pressure by the bulging or expanding effect to the contents of the structure as is most noticeable in silos, g'ranaries cisterns, and

the like, wherein hoops are usually em: ployed for resisting the outward pressure.

The present invention eliminates the use of hoops or hands or embracing the structure, inasmuch as the interlocked blocks will in themselves bebound together to hold them intact, even under considerable pressure from the inside.

From the foregoing, withthe drawing, the advantages and capabilities of the present inventionwill beobvious to those versed further comment being necessary.

Having thus described the invention, what is claimed as new is A curved wall comprising superimposed courses of blocks arranged end to end, each block comprising an arcuate body having a key portion projecting trom'one face intermediate'its ends, and providing end re cesses, and semi-key portions projecting from the other face of the block at its ends, and providing an intermediate recess therebetween, the k'eyand semi-key portions being tapered from the convexed to the concaved sides of the blocks, the first mentioned key portions of the blocks fitting within the corresponding end recesses of the companion blocks, the cooperating semi-key portions fitting Within the intermediate recesse's of the companion blocks. the central portion and key portion of each block having an opening, the ends and semi-key portions of the blocks having channels, the
