To all whom it may concern.

vBe it known that I, Lewis K. Davis, a citizen. of the United States, residing'at New York city, in the county and State of New York, have invented certain new and useful Improvements in Building Construction, of which the following is a specification.

Theobj ect of my invention isvto produce a. building-construction comprising hollow blocks and a hardening plastic (such a's concrete) wherein the blocks will form matrices` for. the plastic to connect the blocks' into a rigid structure. i

The accompanying drawings illustrate my y invention.

Figure is a perspective detail in partial section; Fig. 2 a section axially of blocks of adjacent series and transverselyof the interniediate4 concrete beam, Figs.. 3 and 4 details of modified stoppers`Fig- 'anend elevation of several blocks in Ethe saine series.

'In t-he drawings, 10 indicates a building block of a thickness nearly equal to the desired 'thickness of floor or wall of whiclr it is to form a part; of a width convenient to handle; and a length economical in building construction depending sofnewhat on the loads to be carried. Inlpractice I' fin-d af,

length of three feet to be lconveui'ent both in handling in producing the building and' also for purposes of manufacture. Each of the blocks 1G is provided with a plurality of internal longitudinal passages 11 conveniently and preferably two or four in nuin'ber and' the side walls of these passages are provided- -with longitudinal plastic-holdingribsl 12 which may be of any desired cross section.

The vertical faces of each block are similarly provided with plastic-holding ribs '13 and the yopposed top and bottom' faces are provided with plastic-holding ribs 14,. the ribs 14: being preferably undercut in order to mechanically lhold the finishing plaster and licor surface. Each of the side faces of the block, at its lower edge, is 'provided with a rib 15 of a transverse dimension exceeding the transverse dimensions of the ribs 13` so that two adjacent ribs 15. may be brought close together and at 'the same time leave a desirable vertical'space between the adjacent vertical faces of the blocks. In

order to facilitate the introduction of plastic between the adjacent vertical faces of the blocks I consider it desirable to make ,the

,top of each block somewhat narrower than any suitable means.

vIn' practice Indlit desirable to arrai'ige the 'dains in the upper channels 11 some-l what farther in than .in the lower passages thus forming a beam. 25 substantially T- y shaped in cross section so as to be more eilicient.

If desired, suitable reinforcingmembers .26 may be embedded near thewlower surface of the beam. In practice the concrete wil-l be filled into the adjacent ends of the beam as already described and will also be lled into the space 30 between the adjacent ver# tical faces of the blocks and also spread over the .tops of said blocks vforming the floor surface. It will be readily understood that the lSame blocks may-be used in the productidnjof'a wall if desired. y n

The blocks may he made ofany desired material but I prefer to form the saine of a plastic, such as clay, which may be readily formed by the ordinary tile machine cut in l l J a suitable dieand then vitried so as to be rendered impermeable to moisture. To this end theV ribs, or plastic-holding projections, should have sides which are parallel` with the length of the block.

I claim as my` invention 1. A building construction comprising a -plurality of series of hollow blocks each having a pair of longitudinal passages, the ends of one series being spaced a short distance from the ends of an adjacent series, a

filling of hardening plastic filling the space between the adjacent ends-of two series of blocks and extending into vthe interior passages thereof, and means for limiting the flow of plastic into said tubular passages, said means lying fartherinward in the one series'of passages than'in the other series.

series with lplasticholding` v2. Ar building construction comprising aplurality of series of'blockseach comprising a pair of longitudinal passages and provided on theadjacent faces of blocks of the same series with plastic-holding'.projections, dams arranged'in theends of the longitudinal passages at a greater distance into one pas# sage ofieach block than-into the other, andl also provided upon other cesjvith plastichcldingprojections, dams larranged in the ends of- 'the longitudinal j passages at a projections and greater distance into one passage of each block than into the other, and a hardening plastic filling the spaces between the ends of adjacent series and extending into the passages of the blocks to the dams therein, and filling the spaces between adj aceiit faces of blocks in the same series, and also coverferent distances inward from thedams in the lower passages.

5. A building block having longitudinal oppositely projecting ribs 15 proj ectlng from the vertical faces .of the blocks near the lower corners thereof, said blocks having upper and'lower longitudinal passa-ges, and dams inserted in said passages to a greater extent in one than the other. 6. A building block having longitudinal oppositely projecting ribs 15 projecting from the vertical faces of the blocks near the lower corners thereof, plastic-holding projections formed on the vertical faces of said block above the rib 15 and of less projection than the said rib 15, said blocks havingnpper and lower longitudinal passages, and

dams inserted in said passagesY to a greater' extent 1n one than the other.

In wltness whereof, I', have hereunto set my hand and seal at New-York city, New Yorky this twenty-fourth day of September, A. D. one thousand nine hundred and eight.
