v ing-Block, of which thefollowing is a specification.

This invention relates to Improvements 1n building-blocks or artificial stone, and more tions of the channel 6. .Th

. comparatively'light, and yet I particularly blocks formed of composite material, such asivconcrete.

' The principal object is to provide novel blocks which can be readily manufactured and are comparatively light in weight and economical in the amount of material employed and which when built into the wall will orm therein channels and passage-ways for the circulation or confinement of air.

The preferred' embodiment of tion is illustrated in the accompanying drawings, whereinl Figure 1 is a pers ective view of the block. Fig. 2 is a bottom pllan view of the same. Fig. 3 is a longitudinal sectional view.- Fig. 4* is a cross-sectional view.

Similar reference-numerals designate correspondingparts in all the figures of the drawings.

The block illustrated consists offan' oblong rectangular body5, of concrete or other' suitable material,having inits underside a central longitudinal passage-way or channel 6, that is curved. in cross-section, as illustrated' in Fig. 4. Extending through the block are transversely-disposed passage-ways or circular openings 7, dlsposed staggered relation, thus formingfa pluralityof rows,- said rows communicating with the opposite side lpore openings are of less diameter thanthe webs 8 of the body between them. Furthermore, it-will be observed that one of the rows is composed. of

completely-surrounded openings, while the other has half-openings'Q, constituting recesses in the end of the block. It will be apparent that blocks of this character can be Areadily manufactured. By-'having the double set of openings the blocks are of course they are very strong, for by disposing the openin s in staggered relation and having them of ess diameter than the websbetween them transverse bracing portions are provided which extend directly across the width of the block, and said bracing portions are,

able thickness, obviatmg to a very material Specication of Letters Patent. Application filed July zo, 1905. serial No. 270,557'.

the invenf' moreover, of consider- .|:"atentec1 March 20, 190.

' degreeY the danger of the block becoming cracked. having a double line of openings in a block' having a longitudinal channelis that said openings extend through the thicker portions of the block, and 'thereby eliminate considerably more material than if they were in the center. Furthermore, the thinnest longitudinal central portion caused by the longitudinal channel is not weakened by transverse openings. Furthermore, when the blocks are built into awall such wall will have spaced longitudinal air-channels or passage-ways, all of which w'ill be in communication through the spaced rows of transverse openings. If, therefore, the channels so formed are tapped -at dierent points, air can circulate freely through the walls and keep the same in properly dry condition, or ifit is desired to confine' the air the tapped openings can be closed whenever desired. i 1

From the foregoing it is thought that the construction, operatlon, and many advantages of the herein-described invention will be apparent to those skilled in the art without that various changes inthe size, shape, promay be resorted to without departing from the spirit or sacrificing' any of the advantages of the invention. y Having thus described my invention ,what I claiml as new, and desire to secure by Letters Patent, is-4 l. In a building-block, a body having'an `intermediatelongitudinal channel terminating short of the sides thereof, leaving thicker Vportions on its opposite sides, and va plurality of rows of transverse passage-ways extending through the thicker portions of the -body on opposite sides of the longitudinal channel.

2. In a v building-block, a body having an intermediate longitudinal central channel terminating short of the sides thereof, leaving thicker portions on its opposite,y sides and a plurality of rows of transverse openings exbody on opposite sides of the longitudinal channel, said openings being disposed in staggered relation and communicating with the opposite side portions of the channel, and said o enings furthermore being of less diameter t an the web formed between them.
