f 622 103 March 22 1927. J' o' FULTON n y HARDWOOD BLOCK FLOORING Filed Sent. 2. 1926 INVENTOR Patented Mar. 22, 1927.

'UNITED STATES PATENT OFFICE.

JAMES ORB, FULTON, OF TORONTO, ONTARIO, CANADA, ASSIGNOR TO THE JOHN C.

KTNG: LUMBER COMPANY, OF CLEVELAND, OHIO, A CORPORATION F OHIO HARDWOOD BLOCK FLOORING'.

Application led September 2, 1926. Serial No. 133,150. i

This invention relates to a flooring .con1- posed of a plurality of blocks which may be of wood or other suitable material.

The object of the invention is to provide 5 a block flooring in which each block will be firmly retained in its place by adjacent blocks.

Another object is toprovide a flooring in which at least two edges of each block will l0 be kept from upward movement by adjoining blocks.

Another object is to provide a Hooring which may be readily laid.

Another object is to provide a flooring -in which the blocks may be readily and economically manufactured.

Another object is to provide flooring blocks which will, vwhen laid, not necessitate the `use ofkeys, pins, or other pieces to retain the blocks in position.

Another object .is to .provide a iiooring composed of interlocking blocks, the lower surfaces of which engage the flooring base throughout substantially its entire extent.

Other objects will hereinafter appear.

The invention will be better understood from the description of one practical embodiment thereof illustrated in the accompanying drawing in which:

Fig. l is a plan view of a section of Hoor composed of blocks embodying the'present invention;

Fig. 2 is a transverse section thereof 0n the line 11-11 ofF ig. 1;

Figs. 3, 4f and 5 are, respectively, plan, side and elevational views of one of the forms of blocks used in the flooring;

.y Figs. 6, 7 and 8 are, respectively, views similar to Figs. 3, 4 and 5 of the other form 40 of blocks; and

Fig. 9 is a view similar to Fig. 2 but' showing a modified form ofjoint.

The block flooring is laid upon a suitable base or sub-flooring 1 and held thereto by an adhesive or cement 2. The. blocks are illustrated as of rectangular shape-and arranged in zig-zag or herring bone design, in which the ends of each block abut the sides of other blocks adjacent their ends. In the flooring illustrated, two shapes of blocks 3 and 4 are'used. Those, 3, slanting upwardly and to the right in the plan, are hereinafter referred to as right hand blocks, and are illustrated in Figs. 3, 4 and 5, Those, 4, extending upwardly and to the left in Fig. l are hereinafter referred to as left hand blocks and are illustrated in Figs. 6,- 7 and 8.'

As shown in Figs. `3 to 5, each right hand block consists of a rectangular top 5.and a b ottom 6 parallel thereto and of. substantially the same length and breadth but ofi'- set to the left and downwardly, as illustrated in the plan, from the top.

Along the side edges of the bottom, grooves 7 are provided so lthat there will be a slight space between ,the edges of adjacent blocks at their bottoms, into which the adhesive material, by which they are secured to their base, may How. The ends and sides of the block are plain surfaces, oblique to the top and bottom and, as illustrated, each; form an angle of about 70 therewith, and it will be noted when the block is placed with its longest dimension extending upwardly, and

`one side 8- projecting from under thetop to the' left, the lower end'9 also projects beyond the top, and the upper end 10 and right hand side 11 recede under the top by the same amount.

The block illustrated in Figs. 6 to 8 is substantially the same as thatjust described except that the arrangement of projecting sides and ends is reversed, so that when the block is viewed in plan, with the left hand side 8a projecting beyond the top, the upper end 10a also projects therebeyond, and the lower end 9a and right hand side 11ZL recede thereunder.

With blocks madeas described, a pattern of zig-zag or herring bone design may readily be laid, all right hand blocks extending in one direction and all left hand blocks `in a direction perpendicular thereto, as shown in Fig. 1. and the projecting side and end of each block will t against the receding side and ends of three adjacent blocks, and be firmly held therebeneath.

Each block is sufficiently rigid not to bend or warp and by being held 'along two sides 1M is iirmly held in place by the overlying parts of adjacent blocks, so that no securing means, other-than the adjacent blocks and the ad# hesive between the block and base, are necessary. By' eliminating the necessity for 105 separate keys or the like to join the blocks, the expense of both manufacturing and laying the tloor is materially reduce As the base of the blocks is theV same area as their tops, with the exception o f grooves 119 5, and as these grooves can be made as small as desired, the blocks transmit any pressure imposed upon them to their base throughout the maximum bearing area. The space into which the adhesive material may How may be made as small as desired, so that while allowing for the iiowing of an excess of this lmaterial, no large amount thereof will be ing wasted.

Obviously, my invention is applicable to other floor coverings than those composed of` wooden blocks, for instance, to coverings of such materials as ceramic or rubber tiles, or it may be used to cover walls or other surfaces. Also the blocks need not be rectangular'in shape but may be in the form of oblique parallelograms or any other desired form.

The iinished flooring presents a pleasing appearance such as has heretofore been posslble only with elaborately jointed blocks, manufactured and laid withv excessive labor at great expense.

In Fig. 9 I have shown a joint at 12 between two blocks, in which the side and end surfaces, instead of being oblique, are cut in the form of a step. `As in the form above described, the base of the block projects beyond its top along one side and end and recedes thereunder to the same extent along the others, the projecting side and end of one block engaging and tting beneath the receding side and ends of others.

While I have described the illustrated embodiments of my invention in some particularity, obviously many variations thereof will occur to those skilled in the art to which it appertains, and I do not, therefore, limit myself to the specific details shown and described, but claim as my invention all embodiments, variations and modifications thereof coming within the scope of the appended claims. I
