UNITED STATES PATENT OFFICE 2,021,292 nnocx rnoonma Application March 25, 1932, Serial No. 601,257

' r 7 Claims. (01. 20-23) This invention relates to the art of-wooden block flooring construction. Heretofore it has been conventional practice to construct such flooring of blocks made up of matched parallel 5 strips or sections laid with separately applied edge or border strips between the block units.

It is a seriously objectionable characteristic of such flooring that under climatic conditions of high or considerably variant humidity the wood 10 will increase its moisture content with consequent expansion and distortion of the floor. The average moisture content of the flooring material most widely used is approximately eight per cent. Under protracted dampness such lumber adds at 15 times as high as flve'per cent additional, moisture.

Ina ten inch floor block such addition will cause an expansion of three-sixteenths of 'an inch. Over a floor where hundreds 01 blocks are laid there is inevitable buckling and distortion under 20 such conditions.

Specially constructed spacer strips have been proposed as an expansion compensating means but the use of such, as well as other expedients involving separately laid or applied means, en-

25 tails much higher labor and material cost than in the case of simply laying block unitsalone.

It isan object of this invention to provide a flooring construction made up of block units having self-contained expansion compensating 39 means. 1

Another object is the provision of such a floors ing wherein the self-contained expansion compensating means provides a block unit border throughout a floor.

35 A further object is the provision of a method of forming floor blocks having self-contained exshall not constitute limitations inconsistent with v the scope of the invention as claimed. Figure 1 of the drawings is a plan view of a section of block flooring as constructed in accordance with this invention.

Figure 2 is an extended plan view illustrating the assembly of blocks as shownin Figure 1. Figures 3 and 4 are, respectively, perspectives of block units employed.

Figure 5 is a section on line 5--5 of Figure 1.

Figure 6 is a section similar to Figure 5 but illustrating an alternative embodiment.

Figure? is a section similar to Figure 5 and illustrating another alternative embodiment. s

Figure 8 is a'plan view of a flooring section wherein an alternative structure of block unit is used.

Figure 9 is a fragmentary perspective of a block section having adhesive material applied to 10 the tongue thereof.

Figures 10 and 11 are, respectively, perspectives of further alternative block unit embodiments.

Figure 12 is a longitudinal section through the blocks of Figures 10 and 11 as assembled. 15

Figure 13 is a bottom horizontal section of part of a flooring made up of the units of Figures 10 and ll.

In accordance with this invention floor blocks are made up of short lengths of standard flooring strips, each block being rectangular; in this instance square; and consisting of a plurality of sections, generally three or four depending upon the width of strip materialfrom which the sections are cut.

As best shown in Figure 3, a block I0 comprises three sections Ilia disposed in parallel relation in the usual tongue and groove engagement. A feature of the invention is the manner oi uniting the sections into a block unit through the medium of a glue or cementitious bindingagent lightly applied as a strip H, Figure 9, over the side tongue I! of each abutting section. If desired, the binder may be applied to the groove of a section. Each section is end tenoned to provide end tongue portions 13 which form in the block unit a tongue I! on two opposite edges thereof, while the remaining opposite edges are formed with grooves l5 of the usual depth.

Seated on the upper face of each tongue I and contacting the block face is a strip of resilient material l6, preferably cork, although it may be of rubber or some other elastic or compressible substance. Preferably the resilient strip is rigidly secured in position by a strong adhesive binder. These strips it are rectangular in cross section, and they project at each end beyond the block face a distance equal to their width. V

In conjunction with ,/the block unit just described there is employed another type of block unit, shown in Figure 4.\ Such a block ll consists of sections Ila which are identical with the sections "la of a block l0, having identical end tenons l8 forming a tongue IS on two opposed edges of the block and being grooved on the remaining the various block units In and II are disposed in such manner that the respective block unit sections Illa and 11a are at'right angles. In consequence each plain side edge block faceabuts the resilient strip of the immediately adjacent block. Due to the fact that in lumber where the grain runs longitudinally of a strip expansion is lateral and is negligible longitudinally, the expansive force of each block is directed against a resilient strip which is backed by a substantially constant wall surface, the expansion resultant of each block being directed at a right angle to the resultant of each immediately adjacent block.

In addition, the resilient strip members 2| nest within the projecting ends of the strip members l6, providing interlocking joints and establishing absolute straight line continuity of the resilient strip material across the entire floor, such material bordering each block unit on all sides thereof. This border continuity is clearly shown in Figure 1.

The block units are jointed by the interengagement of the respective tongues and grooves it, I9, l and 20. As the grooves 15 and 20 are of standard depth the tongues 14 and 19 must be of standard length beyond the resilient strips l6 and 2|. The tenons l3 and I3 are in consequence cut longer than standard to accommodate the strips of resilient material and it is in this respect that the invention provides a means of advantageously disposing of waste short end strips from standard flooring. Such short lengths can be cut to provide the requisite tenon length without sacrifice of valuable flooring, as it is not feasible to provide side tenoning of this character on standard flooring. Prior to the advent of this invention the short lengths remaining from the manufacture of standard flooring strips have been largely deemed waste and a drug on the market.

In the alternative embodiment illustrated in Figure 8 the block units 22 and 23 are in all respects structurally identical with the previously described block units and I1 except that the blocks are made square including the resilient strips 24 and 25 of the respective blocks. It is obvious from an inspection of Figure 8 that the border line continuity of the blocks will be staggered at block corners, presenting an entirely different flooring surface effect than as seen in Figure 1.

In some instances, where a high degree of fiooringexpansion is to be encountered it is advisable to provide resilient strips 26 as shown in Figure 6, wherein the width of the strips is greater between the block units 10 and I1 than as shown in Figures 3 and 4. The tenon 21 is proportionately lengthened in this form.

The alternative embodiment as shown in Figure 7 differs from the previously described forms only withrespect to the resilient members. In this form the resilient members between blocks l0 and I1 comprise superposed strips 28 and 29 seated on the tenon. In such case the upper strip required edges.

spouses 28 is of contrast color while the lower, 23, is neutral.

In some instances of flooring block manufacture all four sides of the blocks are grooved and factory finished with inserted tongues on the Such a construction is contemplated in the embodiment illustrated in Figures 10 to 13.

In this form a block 30 is made up of sections 30a, factory united and grooved as at 3| on all 10 four edges. Tongue strips 32 are seated and rigidly secured in the grooves of two opposite edges. These tongue strips are appreciably wider than standard tongues in order to provide seats for strips of resilient material 33 cemented or otherwise suitably secured on the upper face of each tongue strip and contacting the block edge face. The resilient strips 33 are preferably rectangular in cross-section and project at each end beyond the block edge face a distance equal to their width. The tongue strips 32 are made substantially coextensive therewith to support the resilient material from end to end.

In conjunction with a block unit such as 30 there is employed another type of block unit, shown in Figure 11. Such a block 33 consists of sections 34a grooved as at 35 on all four edges and factory finished with inserted tongue strips 36 in the grooves of two opposite edges. These tongue strips, as in the case of the tongue strips 32, form seats for attached strips 31 of resilient material which contact the adjacent block edge face and which terminate at their ends flush with the open grooved block edge faces.

The tongue strips 36 are not coextensive with the resilient members 31 as their length is slightly less than the distance between the bottoms of the open grooves on the other two edges of the block. In all other respects they are identical to the tongues 32. By virtue of such construction as the block units are assembled, the short tongues 36 seat in the adjacent block unit groove 3| between the projecting ends of the tongues 32, with the projecting ends of the resilient strips 33 overlapping the ends of strips 31.

As will be apparent from an inspection of Figure 13, the interengagement of the tongues 32 and 36 at their ends provides a support for the resilient strips 33 and 31 throughout the entire extent of these strips on all edges of each block unit so that there can be no sagging or depression of the resilient material between or at the corners of block units.

The block units are laid in the manner detailed in connection with the block units I0 and i1. and 22 and 23.

The application of the coextensive tongue support principle is obtainable in, the case of the block units l0, I1, 22 and 23 by appropriately diminishing the length of the tongues I3.

I claim:

1. A flooring unit comprising a wooden block having two faces thereof disposed across the grain, and expansion compensating means attachedto said block and forming a part thereof across each of said cross grain faces.

2. In a wooden floor block, a tenon extending from a face thereof in line longitudinally with the grain, and a member formed of compressible material seated on said tenon and contacting the block face throughout its extent crosswise of the grain.

3. A flooring unit comprising a wooden block having a face thereof disposed across the grain, a tongue extending from said face, a strip of 75 compressible material covering the block face above. said tongue, and said tongue being of standard width beyond said strip.

5. A floor block comprising waste short end sections of standard tongue and groove flooring strips united to form a unit, the ends of such sections being cut to form wide tongues, and the ends of the block assembled sections being covered with cork strips seated on the wide end tongues and of a width sufficient to leave the remainder of the tongue of standard width.

6. A block unit for flooring, comprising a wooden'block provided with a tongue extending i from an edge face thereof, a strip of compressible material seated on said tongue against the block edge face, said strip extending over the entire block edge face above the tongue and projecting at each end a distance equal to the width of the strip, and said tongue having a length coextensive with the strip.
