Image Number 7 for United States Patent #5551202.
A timber expander and coupling system both expands at least one dimension of existing timbers and spans two existing timbers. The timber system includes first and second parallel spaced continuous members. Each continuous member includes a first portion extending in a first direction parallel to a timber, and a second portion, extending from the first portion, in a second opposite direction. The first and second continuous members are held in spaced, parallel relationship by either a cross-member, or an expander timber disposed in an expander timber receiver region formed by the second portions of the first and second continuous members. The first portions of the first and second continuous members form a timber coupling region, for coupling to timbers and for expanding the dimension of an existing timber, or for coupling to and spanning the distance between at least two timbers.
