FLOORING.

Application filed July 22,

To all whom it may amwem:

Be it known .that 1, CHARLES J CARTER, a citizen of the. United States, residing at Kansas City, in the county of. Jackson and State of Missouri, have invented certain new and useful Improvements in Flooring and 1 do declare the following to be a full, clear, and exact description of the invention, such as will enable 0 hers skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to flooring and particularly to a unit which may be .so constructed at the factory that it may be laid down on a support or foundation in an expeditious and convenient manner.

Certain types of wooden fioors are laid down in units, each unit consisting of .a base board to which is fastened a plurality of floor blocks. The base boards are generally laid down with their fibers running in th'eusual way, that is, from end. to end. The floor blocks, however, have their fibers running vertically since theyoffer better resistance to wear and tear when the ends of the fibers are subjected to the wear than when the fibers .run longitudinally of the With such a construction it is usually the practice to key the block sections together with the side edges of the blocks grooved so that the sections may be keyed together by strips which enter aligning grooves of adjacent sections. Then nails are driven through the blocks of one section, and throu blocks of an ad acent section.

My invention.

floor section in which. the nails are introbefore the section or unit leaves thefactory. Then it is only drive the nails home; that is,

to build drive them into an adjacent section up the floor.

If the nails are properly set in the sections before the sections leave they can be driven in straight so that their points practicallyv penetrate the sections, the extreme points, however, beingjust inside the skins of the sections so that when the in place, unskilled'labor can be used to drive the nails into the keying strips and into the adjacent section ina convement manner.

- trating a key tion being 'vide dove-taiia gh its keyed strip into the contemplates building a the factory,

1922. Serial No; 578,678.

My, invention, therefore, is confined to a floor section or unit having the nails initially driven into it so that the nails practioally but not quite penetrate the section and with the heads of the nails projecting in grooves so that the tool for nails home automatically finds them as it is moved along the grooves; the nails being long enough so that when they are driven home they may penetrate the key ing strip and enter the next section to which the nail-carrying section is to be secured.

The novel construction of the invention will be clearly understood, by reference to the following description in connection with the accompanying drawings, in which Fig. 1 is a perspective view of a floor section constructed in accordance with my invention.

Fig. 2 is a cross sectional view on the line 22 of Fig. 1, and

Fig. 3 is a horizontal sectional view through a plurality of floor sections, the nails in one section being-shown as penestrip and entering the 'adjacent' section and the nails in another secfloor section.

stri' and a previously laid p invention I shall Inorder to disclose my shown ready to enter the keying drivmg the refer to it in connection with a known type of flooring.

The numeral 1 designates strip having on its upper of longitudinally disposed a base board or tongues 2, to progrooves 3. The tongueand-groove portion ofthe strip 1 inter-engages a similar tongue-and-groove portion ace a plurality 4 on each block 5, the blocks being slid onto the strip from its end or ends.

In practice I prefer to form the blocks sothat the fibers will run from the bottoms of the blocks to the tops so that the ends of the fibers provide the wearing surface for the floor section. This arrangement, however, specifically is not a part 0 the present invention as such a construction has been employed heretofore.

The blocks have their side edges, front and back, provided with aligning grooves 6 and 7, the grooves running transversely'of the blocks but longitudinally of the section so that elongated front and back grooves are provided for the section, as will be clearly apparent by reference to Fi 1. The front sides of the respective bloc are provided with recessesor countersunk portions 8, ep-

- I he nails are introduced concentrically of the countersunk or recessed portions 8 and are driven into the block until their points 11 are practically to the surface of the walls 12 of the grooves 7 and their heads extend out of e, recessed portions 8 and 'e in the grooves 6 or outwardly from the wall portions 13 of the grooves 6. The purpose of permitting the nail shanks to extend across the grooves 6 is to allow a punching set to be introduced elongated groove formed by grooves 7 to automatically Thfin the set can be operated to drive the na Each key strip 14 is approximatel twice the width of a groove 6 or 7; y

A nail set can then be run along the alignlng grooves 6 until it comes into contact with The nails can be driven that the second section will, be fastened to the first. Another key strip'14 will then be introduced into the aligning grooves 7 of the blocks of the second section and a third section can be lined up after the manner of the st and second. again be driven home.

It will be observed that I do not provide nails in all of the blocks. Certain blocks in each section may be provided with a nail and only necessary to operate a .nail set in home. The section e nails in one section will not align with the nails in another section, as clearly seen in Fig. 3, so that when the nail pointfrom one section penetrates another section, it will go directly into a block a recess, thereby insuring a rigid construccompleted.

For the purpose of illustration I have shown my invention as applied to a typehof floor, but I do not wish to be-llmited to t sections may be made of solid strips or units and secured together in substantial] the manner shown.

What I claim ters-Patent is:

As an article of manufacture a floor section consisting of a base strip, a plurality of locks mounted on the base strips, the blocks having aligning grooves in their opposite vertical faces for receiving splines, some of the blocks each having a recess opening from the base of one of its spline grooves and desire to secure by Let the bl ing into one spline groove and their points terminatin short of the other-spline groove, whereby when the sectionis lald against a i e section the .nails may be driven on through the blocks and throu h a spline into the abutting blocks of said like section.
