A wood burning stove having an enclosure in which is located a first, V-shaped baffle plate extending horizontally from the front wall of the enclosure but spaced from the rear wall thereof, a second flat baffle plate having a rear edge in engagement with the rear wall of the stove enclosure and extending across the enclosure with the front edge thereof spaced from the interior of the front wall of the stove to define a vent space leading from the rear of the enclosure over the top of the V-shap...

A roof structure of the type having a plurality of wooden beams whose sides are provided with mortices for receiving end edges of roofing panels. The invention improves the strength of the structure by employing a generally zig-zag or corrugated cross-section by arranging the mortices such that at least a major portion of each mortice extends at an acute angle with respect to the elongation of the beam, which generally corresponds to the direction of wood grain. The invention thus provides the a...
