FLOORING.

Application led November 11, 1924. f Serial No. 749,149.

This invention relates to sectional or block flooring. or surfacing.

This invention hasutilityvwhen incorporated. in wood block flooring wherein the blocks are sealed intheirA grouping for `knitting together into a unit. z

Referring to the drawings:

F ig. 1 is a fragmentary perspective view of an embodiment of the'invention in an interior flooring; f

Fig. 2 is a view similar to Fig. 1 in which the blocks are of a different form than the showing in Fig. 1;

F ig. 3 isa view along the side of an intermediate row of the blocks of Fig. 1 as in a flooring, showing the sealing ilow andg-Fig. 4 is a perspective View on an enlarged scale, of one of theblocks of Fig. 1. 'v

A structure is shown having :doorway 1 fromA which extends sidewall 2 of a room having subfloor or base 3, over which as a continuous sealing coating is=a layer 4. In factoryfloors or, places exposed or subjected to weathering or extremes in temperature or n moisture, with the blocks of wood, such seal-l ing coating may advantageously be a resin, pitch, tar or bitumen. As a self setting or hardening coating, after such layer 4 is more or less set but of effective adhering properties, blocks 5 are laid in adjacent or abutting rows thereon, preferably with the joints staggered as between adjacent rows. In such grouping of the blocks 5 on the base 3 to be sealed thereto by the layer 4, the blocks 5 have the grain of the wood thereof on end, or extending away from the base 3. p

The blocks 5 have their upper or wear faces 6 expose the age rings of the wood. Grooves 7 extend vertically across the face of longer side 8 ot' the block 5 away from the wear face 6. Groove 9 parallel to the grooves 7 extends across narrow side or end 1() of the block 5 away from` the face 6. Lengthwise of the side 11 as opposite the 7 longer side 8, and parallel with the wear face 6 extends crosswise groove 12. Short side 13 opposite the short side 10, has cross'- wise of the grain groove 14 extending from the groove 12.

As grouped or assembled in the flooring on the base 3, the grooves 12, 14, crosswise of the grain of the blocks 5, extend parallelto the base 3, while the grooves 7, 9, parallel to the grain of the blocks 5 extend away from the base 3. The blocks 5 as preferably :desirably similar to orone which may seal ilaid, have grooves intersected by grooves '12, and the-grooves 9 intersected by the grooves` 14. lnthel completion of the flooring, sealing material 15, as a filler, which is with the coating 4,\ is poured into the grooves 7, 9, squeegeed over the wear faces 6 for flowing into the grooves 7, 9, or as found convenient introduced to effect sealing knitting between the blocks 5, as well as supplementing the connectionl of the blocks to the'base 3. When this sealing. material L15`is a liquid, aspitch, itfisdesirableto thin such 'by heating, soit may iiow more freely, and still on getting back to 'the normal temperature to which the flooring is to be exposed, is set or hard. .It is, however, desirable not to have such Sealing material brittle, but almost plastic. v

As the sealing mater'al15 is flowed into the grooves 7', 9, say as starting along a oint between adjacent rows and taking care of the staggered joints of abutting sides 10, 13, therefrom, the progress of thev pouring along the adjacent sides 8, 11, is continuous so that any air entrained by the material 15 as clogging the exposed end of a groove 7, may escape along the vent crosswise grooves 12, 14. This release of support tends to permit the ready flow of the material 15 into the grooves 7, 9. In practice, this material 15 may readily settle below its point of i11-r troduction a given distance-say three quarters of an inch. l/Vith such ascertained condition as to the action of the material 15, it

vis desirable .to have such distance as a maximum for theI spacingof the vent grooves 12, 14, from the base With this proportion maintained, the grooves l2, 14, so vent between the grooves 7, 9, that the pouring or squeegee application of such material 15 is at once, not only down to the grooves 12,14, but the normal settling distance of the Inaterial 15 toward the base 3 beyond these` grooves 12, 14. The volume of air below the vents 12, 14, is not such as to sustain the material 15, andonce the material 15, even for an attenuated stream portion thereof makes connection with the coating 4, there is surface tension release and effective sealing develops. The quantity of the sealing material 15 which it is possible to introduce between'the blocks 5 on a single pouring is thus elfective, not only to supply a knitting seal between the blocks as crosskeyeddue to the intersecting grooves 7, 9, and 12, 14, but is of such extent that such interconnection between the blocks is maintained even after extended intervalsof time and arduous wear, even of vehicle traffic,

for the sealing is also of the blocks to the base 3. While initially, the single pouring may not fully charge the grooves, such pouring so nearly approximates. such condition that the slight settling in the final complete .sealing of the material 15 with-the coating .4, leaves the grooves 12, 111, submergediby the material 1 5 upward therefrom in the grooves 7 9.V l f o Groovesl, in blocks Fig. 2, are in pairs adjacent intermediate projection 17 .as a

countersunk lug, but are assembled and con act inthe flooring with the sealing material as flowing therealong into `and past the. crosswise grooves 12, 14. As the projections 17 are beyond the vertical faces of these blocks 5, the material lmay extend as V.a more or less thick sheet or iilm fin sealing the vertical faces of the blocks as abutting,

.thereby being a `factor in housing the floor,-

ing block or section with an antiseptic or preservative as to al1 portions thereof not `open to direct wear.

cial regions are not air pockets,but block n Tendencies to warp or curl, even with ,blocks of greaterwidth v than depth, are minimized, if not fully eliminated. While each block is separately supported,'the sealingknits such blocks into a homogeneous flooring. v

What is claimed and itis desired to secure by Letters Patent is: v A iooring comprising wood blocks of right general parallelopiped form having on two adjacent sides grooves parallel to the grain of the wood) of the block, and extending from the` wear-face ofthe block, and on the two adjacent remaining sides as .extending from said wear 4face having communicating grooves crosswise of the grain of the wood of the block, said blocks as in rows in the flooring having the crosswise grain grooves intersecting the parallel to the grain grooves Y of adjacent blocks and accessible 'solely through the parallel grain grooves, and seal- 111g means for uniting .the rows of blocksV into al flooringV by flowing lengthwise of the parallel to the. grain grooves from the wear face of the blocks, with vent relief of such flowing provided by said crosswise grain grooves for flow of sealing means` from the parallel grain grooves into said intersecting graingrooves. l

In witness whereof I affix my signature.
