' Application filed February 23,1929. Serial in}.s ..;,287.' Q

a This invention relates to. a building block of concrete or similarmateria l, with special reference to its use inthe construction of chimneys;

The general object; of the inventionto provide a block of thi's kind having novel and improved features which facilitate the setting of the blocks, which hold the fine-lining incorrect position, and which serve efficiently as a heat lnsulator.

These various features, in their preferred embodiment, and the advantages resultmg therefrom, will be more particularly e'x jplalned in connection with the 'accompany-' ing draw1ngs,' 1n whlch Figure'l is a plan view of a block made according to the lnventlon. I Figure 2is a slde elevation of the same with I a portion broken away on the line 2+2 of Figure 1. I

I Figure 3 is an isometricview illustratingthe adaptation of the invention f-tofchimney j ft will be under'stoodthat these-blocks can construction.

As illustrated in the drawings, thejblc ick 5 is in the form of a'hollow square, although its precise shape is not material tothe invention. The walls oftheblock are formed on their lnner faces with vertically disposed ribs 6, within which" the :flue lining 7 has a close fit. The wallsof thejblock are formed with a series of air pockets 8 which extend from its bottom face nearlyto thetop of the These pockets serve as 'a non-con ductor of heat'from theflue to the outside of, thewall. In'makingthe block these pockets block.

are formed by cores secured to the'support on which the pallet rests and the pocketsare preferably tapered to facilitate the iwiths 'drawal of the cores when the block islifted from the mold.

The upper faced the block formed with V a channel 9 which preferably extends continuously about the block near .its 7 outer edge and the bottom' face of the block is formed with a ridgelO adapted to mate with r the channel in asimila-r blockdisposed there beneath.

In laying the blocks one above the other, the

cementror mortar may be sprea'din the channel 9 and'the next block laid 'thereon without anyof the cement or mortar Working into the air spaces. The ribs G'serve as accurate guides to retain the flue llm-ng in position and may 'beeasily chipped off in caseasection of the I flue lining is slightly oversized, while the spaces between the ribs serve as additional a r ispacesto. prevent conductionyofheat to the y outer surface of the chimney. v I 'Half blocks,'as shown at 11, maybe made by in'serting-a'partition plate across thecene0 ter of the mold. These half blocks may be laid' adjacent the main chimney toprovide fora smaller auxiliary flue 12, and when so la-id, maybe bondedt'o'the main chimney by angular metallic strips as indicated at13,or c5 eitherof the flues as indicated at 14 "by in- 7b serting cores in the molds, so thateach of-the adjacentblocks provides half of the r open-f block, it is apparent that the various f ar)" turesthereof may be considerably modified without departing materially. from the scope I of the invention as claimed. What I claimis:

1. A chimney block-having" side walls'sa i formedwith internalvertical ribsconstitutng 'ing, leaving continuous vertical air spaces at thesides'of each rib, a channel inthe upper face of, each sidewall, a ridge on the -.lower face of each side wall inate' with the corresponding channel in guides adapted to fit againstthe flue linand adapted to similar block disposed therebeneath, and tapered air pockets extending'upwardlyfrom the bottom surface of the blockin the planes of the ridgesand terminating below the up-' per surfaceofthe block." r I I 2. A chimneyblockhaving a'chann el'extendingabout its upper face between the innerand'outer edgesthereof, a ridge-onthe 1 lower face of the block adapted to mate with the corresponding channel in the upper face of a similar block disposed therebeneath, and tapered air pockets extending upwardly from the bottom surface of the block in the planes of the ridges and terminating below the upper surface of the block.

In testimony whereof I havefhereunto signed my name ,.to this specification. v
