Abstract
Timber connectors in the form of initially flat plates each having a portion containing a plurality of apertures with at least one tooth or barb or a series of teeth struck from the plate and turned inwardly from the bounding edge of each aperture, and a portion devoid of teeth but containing a row or rows of spaced aligned holes for fastening means in the form of a preferred type of nails or other suitable fastener as desired. The aforesaid aligned holes provide lines of weakness whereby part of the connector can be bent on the job site for engagement with a main supporting timber. The connectors can be supplied on the ends of timbers by a power press at the plant pressing the teeth into a timber, and shipped to the job site in strapped bundles as lumber is usually shipped.
