'9 Claims.

This invention relates to flooring or pavement, and with regard to certain more specific features, to a wood or similar type of flooring or pavement.

Among the several objects of the invention may be noted the provision of a herringbone or similar floor having provision for an improved keying system; the provision of a floor of this class in which individual short pieces or lengths seek their own proper level on the more or less 11'- regular base and which are keyed in such manner that the said advantageous conditions are maintained; provision of a floor of the class described which may be easily laid and repaired; and the provision of one which is stronger and economical to manufacture and maintain. Other objects will be inpart obvious and in part pointed out hereinafter.

The invention accordingly comprises the elements and combinations of elements, features of construction, and arrangements of parts which will be exemplified in the structures hereinafter described, and the scope of the application of which will be indicated in the following claims.

In the accompanying drawings, in which are illustrated several of various possible embodiments of the invention,

Fig. 1 is a plan view of a partially laid floor, embodying one form of the invention;

Fig. 2 is an isometric view of one of the floor units or lengths;

Fig. 3 is a fragmentary, enlarged detail of one form of key;

Fig. 4 is a fragmentary, enlarged view of another form of key;

Fig. 5 is a horizontalsec'tion taken through a portion of the flooring of Fig. 1, said section being taken at the elevation of the keys;

Fig. 6 is a fragmentary plan view similar to Fig. 1, showing a modification; and,

Fig. 7 is an isometric view of a unit or length ofthe floor of Fig. 6.

Similar reference characters indicate corresponding parts throughout the several views of the drawings.

I have discovered that the best form of flooring is that which is made up of a plurality of short lengths-of wood or the like, each unit of which, when applied to irregular foundations, immediately seeks its own ultimate level. These short lengths may be subsequently machined and/or sanded to effect a common flat top surface and thereafter, each transmits to the founadation its proportional part of the load imposed upon the .floor. 'I have found that longer lengths 1933, Serial No. 686,867

of wood bridge irregularities in the foundation and later bend at the bridging portions, thus tending to throw their loads to other pieces by Way of the key means used, and thus to introduce fatigue and. final breakdown along edges of adjacent lengths. Shortpieces are also advantageous in that for a given quality of ultimate finish, a lower initial grade of lumber may beused. This is because short pieces may easily be out to avoid knots and other blemishes, whereas this 635 is more difiicult to accomplish with long pieces. Furthermore, for reasons which need not be detailed, it is at present considered that 2. herringbone pattern forthe layout of the short pieces is desirable. The purpose of the present inven- 27!) tion, therefore, is to properly key herringbone flooring at minimum expense, and with maximum advantage.

Referring now more particularly to Fig. 1, there is shown at numeral 1 for example, a concrete 375 base upon which asphaltic or like mastic 3 is spread to form a seat for the wooden floorin per se.

A flooring block per se is isometrically shown at numeral 5 in Fig.2 the same compr a simple rectangular block having triangular notches '7 placed in opposite corners-9 by a saw or otherwise. These notches 7 may be cut at any elevation in the blocks including the mid plane but I find that it is preferable to cut them to- 385 wards the bottom of the block so as to leave a substantial amount of material 11 available at the .top of theblock toresist wear and deformation. If the notches 7: were out halfway between the upper and lower faces of the blocks, all blocks {all would be identical and such a form is contemplated herein for thick blocks. 1

When the notches .7 are nearer the bottom, as illustrated, then rightand left-hand forms of block are used. What may be referred to as a right-hand block is shown in Fig. 2. A left-hand block is the same except that the notches 7 are out in the opposite corners 13, indicated in Figs. .1 and 5. The purposes of the notches 7 is to receive the key memberssuch as shown in Figs. 3 and 4. The form of Fig. 3 is preferable and comprises a length of wire 15 crimped as shown. The diameter of the wire is such as to provide a snug fit in the notches '7. p

Another form'of key composed of fiat wire 17 "is shown injFig. .4. The fit. between this flat wire and the notches 7 is also a snug one. Other forms of keys maybe used. as will appear.

To lay Aa floor, one of the blocks 5A is laid laid in position.

down, preferably parallel to the side of the room, though not necessarily so. A length of the key (say key 15A) is forced into one of the notches '7, the remainder of the key lying at a diagonal with respect to the block and room.

Thus the block lettered 5A is first laid down and the key 15A is inserted in notch 7, then block 5B is applied in the direction of the arrow shown thereon, its notch 7 encompassing a portion of the key 15A. Next block 5C is applied in the direction of the arrow shown thereon. Next, block 5D, as shown. The consecutive letters of the alphabet, taken in connection with numeral 5 and the respective arrows, indicate theprocedure for laying one herringbone pattern in Fig. 1.

The adjacent herringbone patterns are built up analogously, as indicated by the serial indexes. It is to be understood that this is not the only way or" laying the floor, but it is an indication or how each strip may be used for aligning the next and applying the same to the key which is already It will also be understood that when the series of blocks 5B5L are in position, that the key 15B may be applied to the opposite plurality of the notches '7 in said blocks. The same is true of the key 15C in the notches of the series of blocks 5A5K.

If the fiat wire key of Fig. 4 is used, the same procedure is followed, as would be true of any other key. It is to be understood that keys of any material may be used such as wood, composition,

metal and the like, and that they may be fiat, round, straight, or crimped, and/or of Various other forms which will serve the purpose.

From the above it will be seen that it is preferable to have the center line CL of the respective key pass through the centers 19 of the ends of the block, as indicated in Fig. 1. Therefore, the

depths of the notches Z'should be such as to include the centers 19 plus a distance which will accommodatesubstantially one-half the Width of the key being used. The depth may of course be greater but for a symmetrical arrangement should not be'less. However, in making the notches 7, material should not be cut away to such a depth that the adjacent, unnotched corner is unnecessarily weakened.

From the above it will also be seen that each block can seek its own level with respect to the irregular mastic 3 on the irregular concrete 1, and thus transmit its proper proportion of the load which is imposed upon the floor. This action is further facilitated when no tongues or grooves are used on the sides of the blocks 5, as illustrated in Figscl to 5.

At the same time that the above advantages are obtained, opposite corners of the individual pieces are properly anchored but adjacent, diagonally disposed corners are maintained strong by notbeing notched, Any warping that may occur 'to an individual piece is not transmitted to any adjacent pieces to any substantial degree. Thus extended bridging of the floor is minimized. Also,

.the flooring is diagonally braced in the plane of the blocks wherebyresistance to endwise movement is made a maximum for all blocks, with a ,minimum amount of keying material.

'bone patternn ,Itmay then be out by introducing -a sharp tool between adjacent blocks and cutting a key. After a few blocks are liftedout, separaftionof the remainder from the keys 15 easyset forth.

Thus the flooring may be taken up with less trouble than ordinary tongue and groove flooring.

In Figs. 6 and 7 is shown how the invention may be applied to flooring in which it is desired to use tongued and grooved material. A block of this material is indicated at numeral 21, the same being provided with a groove 23 and a tongue 25,. Endwise grooves 27 are also used. Below the tongues and grooves are placed the notches '7 in the manner as above directed. The flooring is assembled in the same way as above It is to be understood that the nontongued modification is the most desirable as it minimizes bridging but some may prefer tongued and grooved material.

In View of the above, it will be seen that the several objects of the invention are achieved and other advantageous results attained.

As many changes could be made in carrying out the above constructions without departing from the scope of the invention, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
