Patented Aug. 29, 1933 UNITED STATES LAYING Woon BLOCK FLOORING William F. Livezey, Philadelphia, Pa., assignor to E. L. Bruce Company, Memphis, Tenn., a corporation of Delaware Application October 4, 1930. Serial No. 486,457

2 Claims. (Cl. 20-7) My invention relates to parquetry ooring made from wood block units laid over a concrete or other solid sub-floor and secured thereto by means of a plastic cement between the blocks and sub-floor. The cement is first spread on the subiloor in a thin layer and then the block is placed in approximately its iinal position and then pulled or shoved into nal position so that the tongues and grooves of adjacent blocks will interflt. It is found in practice, however, that in pulling the block into its final position, the plastic cement crowds up along the edge of the block and espem cially just under the tongue that runs lengthwise of the strips and may ultimately on that account come through to the surface of the floor and stain it if the cement is a bituminous one such as is usually used.

One of the objects of my invention is to so modify the construction of the block and the method of laying it, that there Will be no such crowding up of the mastic along the edges of the block as it is moved into final position during laying, as to cause seeping through of the mastic to the surface oi the oor.

Referring to the drawing for a more complete disclosure of the invention,

Fig. 1 is a perspective view showing the blocks in position on a subfloor, 1

Fig. 2 is a bottom plan view of a block, Fig. 3 is an end view of the block shown in Fig.

Fig. 4 is-a fragmentary vertical section showing a block in its approximate final position, and

Fig. 5 is a similar fragmentary vertical section showing the block in its final position.

The blocks 10 are laid on a subiioor 11 and interposed between the blocks and sub-floor is a plastic cement 12 that is rst spread on the subfloor in a thin layer and then the blocks are placed in position on top of the cement. The block may be made oi separate ooring strips 13 united along their edges by tongues 14 and grooves 15 and having the conventional hollowback 16. The strips may be securely-tied together by a metal spline 17 or other suitable fastening device. 'Ihe blocl-r may be made of one piece or a plurality of pieces tied together.

The block shown has an integral tongue 18 along one side and an integral tongue 19 along the other side, the corner 20 being cut away so that the blocks of the panel can be tted to gther. Instead o1' a tongue 19, a groove may be located at this point,. in which ca'se removable essential that the corner underlying the longitudinal tongue be cut away to accomplish the desired purpose.

The'cutaway portions 2l and 22 should preferably not extend all theway up to the tongue 18 or the groove 23. By leaving an uncut section 24, below the tongue 18 and groove 23, the mastic is further prevented from being forced up through to the surface of the iloor.

As shown in Fig. 4, the block on the right is placedat on the mastic in its approximate nal position. When shoved up to its nal position as shown in Fig. '5, the mastic will crowd or roll up into the groove, as at 25.

, I claim:

1. The art of making parquetry ooring from blocks made of strips of wood secured together to form a unit, the said blocks being joined to each other by tongue and groove connections to form a floor panel and laid in a non-setting plastic mastic that is spread on a subfloor, the improvement comprising laying a block, having a cutaway portion below the tongue and groove connections, in its approximate final position in the iloor' panel, iiat on the mastic, then sliding the block .into its nal position to cause interengagement of the said tongue and groove connections, the said cutaway portion providing a recess, for the excess mastic that rolls up in front of the block, and which inhibits seeping through of the -mastic to the top of the i'loor panel.

2. The art of making parquetry iiooring from blocks made of strips of wood secured together to form a unit, the said blocks being joined to each other by tongue and groove connections to form a floor panel and laid in a non-setting plastic mastic that is spread on a subfloor, the improvement comprising laying a block, having a cutaway portion below the tongue and groove connections. and an uncut section intermediate the said tongue and groove connections and the cutaway portion, in its approximate ilnal position in the oor panel, flat on the mastic, then sliding the block into its iinal position to cause interengagement of the said tongue and groove connections, the said cutaway portion providing a recess for the excess mastic that rolls up in front of the block, and in connection with the uncut section, inhibiting seeping through of the mastic to the top of the iloor panel.
