PARQUET rnoonne.

Application sied' November 17, 1921. serial ne. 515,750.

' To all lwiz-om 'z't may concern.'

Be it known that I, WILLIAM A. PARSONS, a citizen of the United States,and resident `of Milwaukee, in the county 'of Milwaukee and State of Wisconsin, have invented cer` tain new and useful Improvements in Par.- quet Flooring; a'nd Ido hereby declare `that the following is a full, clear, and exact description thereof.

My invention is a parquet flooring.' It

contemplates the utilization ofblocks which may be made from waste material in a structure whereina plurality of the blocks -are united by alongitudinal tongue extending through grooves. 'When a number of` these blocks are as- .sembled andV thetongue is ,inserted to unite them, they are used as a unitin a. larger structure. A series of these units are assembled and vlocked ltogether by suitable tongue and. groove connection, and long transverse and longitudinal members are utilized to form afirm and stable flooring,

'.vention will appear as the description prothe transverse and longitudinal members being suitably secured to the series of units.

The blocks are sawed cross-grained soas create a stronger structure.

Other advantages and objects of my inceeds.

Reference is had to,

Figure 1, wherein aplan view'is shown of a ortion of flooring.

' 4igure 2 is a cross section on the line '2 2 of Figure 1. u

Figure 3 is aperspective of a unit, and

Figure 4 is a bottom view of an alternative modification. Figure 5 shows a cross sectional detail. Unit 10 consists of a series of similar shaped blocks, three in number, which are grooved to receive pigeon-tail 12, which extends the entire len h of the three blocks andunites them rigid y together. A tongue 13 is provided on one side and a groove 14 on theother.

Figure 2 illustrates the manner oi?l as- '.sembly of the units. A unit 11 is immediately contiguous to units 10 which are adjacent to each other. Unit 11 is provided .17" for nengagement z If desired, the units'rnay ho ding said `blocks together,

' I have hereunto with twogro'oves luuonopposite sides. Transverse members 16 are provided with tongues inthe grooves 'in the units. across transverse member 16 beinggrooved to receive aportion of transverse member 16, asshown at 18 and in Figure 5.

The precise form ofpigeon-tail 12 illustrated Ais not necessary in my invent-ion.

be connected b-y a cylindrical rod, block being bored to receive same. Asshown, pigeon-'tail 12 'projectsbelow the Vbottom of the block* in order to space it properly from the Hoor, as is apparent in of moisture beneathV the If desired, suitable tongue 'and groove connection may be made between the longitudinal members 17 and the series of blocks.

In the modilication shown in -Figure 4,

six blocks are used to aeach unit instead of the three shown in Figure 3.

. From the assembly of the unit shown in Figure 3,a square formation, as shown in Figure 1, resu ts.

bly of the modifica-tion,

is substantially similar. As the length s of ay block 18 is twice its widthgthe unit shown in Figure 4 has thesame dimensions as that shown in Figure 3. In all modifications of Ithe device, the blocks are sawed cross grained so as to create a strong structure, theiiooringthus revealing the grain of the wood cut across. I claim: c A ralityof blocks,each having a groove directed-upwardly from its bottom surface, and a igeon-tail fitting into said groove and said pigeontail extending below the bottom of said blocks. In testimony that -I claim the foregoing set my hand at Milwaukee, in the county of Milwaukee and State of Wisconsin. e
