\\'ashington-Cumulative nail resistance is a key factor minimizing expansion in hard maple floors, according to Gerald F. Prange, technologist of the Timber Engineering Company research laboratory. Tlris point was made by trtr. Prange in his address before the joint meeting of the \\'ood Industries

I)ivision of the American Society of Mechanical Iingineers and the Northeastern Section of the Forcst l'roducts Research Society, December 4, in Nerv York City.

Flooring tests, conducted at the Teco laboratory for the llaple Flooring \Ianufacturers Association, shou'e<l tl'rat the degree of expansion in hard maple floors is affected by the u'idth of flooring strips. Considerably more expansion occurred in test panels oi 3t/a inch strips than in the narrower ones, llr. I'range reported. He explained that narrower strips perrnit more nails and thus have the advantage of greater cumulative resistance to pressure create<l b1' the flooring s'hen it attempts to expand.

-\nother factor revealed by the tests is fiber compression at the joints, caused b1'expansion pressure. Again. narro\tr'er strips showed less expansion, this tirrre <lue to the greater number of joints to take up or absorb the pressure.

In studying causes of buckling, \'Ir. Prange reprlrtcrl evidence that conventional tongue-and-groove tiesign. rvith its snrall contact area, tends to cause a cumulation of stresses, near the surface of the flooring, u'hich ma.v result in buckling. He pointed out that a slight modification in design, providing more contact area, was tested and found superior in resistance to bucHing.
