ABSTRACT:
In a tongue and groove joints the base of the groove is provided with one or more protuberances to space the tongue from the base of the groove. If the members forming the joint are such that they swell when moist the protuberances are made to be deformable to permit the members to swell without deforming the structure made from the members.
