rARoUE'r-rLooRInG UNIT.,

Application filed February-28, 1925. Serial No. 12,380.

or sections by cutting the flooringin lengths,

in proper ratio to the face of the 5 flooring The small pieces fastened together with tongue and groove on sides and ends and all interlocking tongues flooring and gluing them as above mentioned. After applying the. glue, the squares are put in clamps with pressure applied on all four sides which bring all joints perfectly tight together. Time is allowed for the glue to properly set and harden and then the square is sanded, scraped and finished to a perfectly After this smooth surface has been obtained, the square will then be finished with shellac, varnish, rubbed or wax finish or any other finish that is desired,

thus making a floor complete ready forlay ing down.- If desired, however, the section or square will be sanded, scraped and'finished to a perfectly smooth finish and then laid on the floor, after which the varnish, shellac, wax or other desired finish can then be applied.

The shellac, varnish, wax or other desired finish will be optional either before or after laying, but in all cases the section or square will be furnished with a sanded, scraped and perfectly smooth surface.

These sections or squares will be a great time saver as they can be easily and quickly installed on .a floor. r

While the invention is mainly designed for flooring and will be described as such, it must be understood that it will be used for wall and door panels, ceilings, table and desk tops and the like.

Another object of the invention is to make up the. sections or units of squares which are composed of a number of, blocks so that different designs can be secured by placing the squares an the blocks composing the larger squares in different positions.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts,to be hereinafter fully described, illusand grooves Will be glued together. The

trated in the accompanying drawings and specifically pointed out in the appended claim.

' In describing my invention in detail, reference will. be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in WlllCl'1Z Figure 1. is a plan view of a portion of. a flooring constructedin accordance with my invention. J

1 Figure 2 is a perspective view of one of the sections for forming the flooring.

Figure 3 is a perspective View of one of the blocks.

' portion broken away.

As shown in these views, the flooring is composed of a plurality. of sections or units 1, each unit or section being composed ofa pluralityof squares 2 and each square being composed of a number of blocks 4:. Each block has} a tongue 5 at one'side and a groove 6 'at its opposite side and a tongue? at one end and groovef8 -atits opposite end, the tongues 5 and 7 joining. each other at one corner of the block and the grooves cutting off the ends of the tongues at two corners of the block. The tongue 5 of one block is placed in the groove 6 of an opposite block and a third block has its tongue 5 placed in a groove.6 of the first block so as to form a square 2. The blocks are glued together under pressure and then a plurality of squares are glued together by their exposed tongues being placed in grooves in other squares to forin the section or unit 1. Of course, the squares can be composed of any number of blocks and the sections of any number of squares. By placing the squares in various positions in the sections, different designs can be secured, as shown in the drawings, where the blocks extend in opposite directions in abutting squares. After the sections are formed by gluing together the squares, the top surface is sanded,

scraped and finished so that Whena number of sections are laid down, the flooring is complete and does not require further finishin This invention will greatly assist the builder as he can lay floors or the like in sections instead of piece by pieceas is now done, as the work of fitting the small pieces ot blocks together, sanding and scraping them, will be done in the factory before the flooring is sent out.

A sheet ,9 of sound-proof and moistureproot paper is glued to the back of each section or square before it leaves the factory.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily ap arent,

I desire it to be understood that may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claim.

What 11 claim is A parquet flooring composed of a plu-,

neeaae? each square being formed of a number of in terfitting blocks, said blocks having fiat faces and being formed upon one side and one end with-a roove disposed midway between the faces t ereof, and a tongue formed upon the opposite'side and opposite end and disposed midway between the faces thereof whereby the tongues of one block will be titted into the grooves of the opposite blocks in forming the squares and whereby the tongues remaining from the squares will interfit with the adjacent squares to provide a section, the squares of each section being so arran ed whereby the tongues and grooves 0? each section will readily interfit to. form a solid structure and means applied to one face of each section for retaining the squares thereof against movement.

In testimony. whereof li alhx my si ature.
