Abstract The connector plate has a plurality of slender nail-like teeth struck to project at right angles to the plate for embedment into adjoining wooden members. The teeth are struck in longitudinal rows with the teeth in each row being staggered longitudinally relative to the teeth of next adjacent rows. The teeth in every second alternate row are struck such that the slots left thereby in the plate extend from the teeth in like directions while the teeth in the next adjacent alternate row in are struck such that the slots left thereby in the plate extend an opposed longitudinal direction to the slots formed in adjacent alternate rows. The teeth in the rows between such alternate rows are formed in longitudinally spaced pairs with each pair of teeth struck to jointly define a slot in the plate, the teeth being located at opposite ends of the slot. These paired teeth are shorter in length than the length of the teeth in adjacent rows and are twisted about their longitudinal axes when struck whereby increased resistance to withdrawal is effected. These short teeth have oppositely scarfed tips to provide a clinching action upon embedment into the wooden members. The tips of the longer teeth in the alternate rows are chisel-pointed providing optimum penetration characteristics upon embedment.
A connector plate for joining members in abutting relationship comprising: an elongated plate, a plurality of elongated projecting nail-like teeth struck from said plate thereby leaving a plurality of slots in said plate, said teeth projecting from one side of said plate, said teeth being struck in longitudinally extending generally parallel rows, the teeth in first alternate rows being struck such that the slots left thereby in said plate extend from the teeth in like longitudinal directions, the teeth in second alternate rows being struck such that the slots left thereby in the plate extend from the teeth in opposed direction to said slots formed in said first alternate rows, a row of teeth between each of said first and second alternate rows with the teeth therein being struck to form a plurality of sets of longitudinally spaced pairs of teeth, the teeth in each set being struck such that a continuous slot is left in said plate between said teeth in each set with the portions of the slot left by each tooth of each set extending therefrom toward the opposite tooth of each set, successive teeth in said first alternate rows thereof being spaced longitudinally and relative to said sets of teeth in next adjacent rows such that each successive tooth lies between each successive set of teeth, and successive teeth in said second alternate row thereof being spaced longitudinally and relative to said sets of teeth in next adjacent rows such that each successive tooth lies between said pairs of teeth forming said set.
