Abstract
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 alternate rows are struck such that the slots left thereby in the plate extend from the teeth in like directions. 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.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
230 words
A connector plate for joining wooden members one to the other comprising: an elongated sheet metal plate, a plurality of elongated naillike teeth struck from said plate to project to one side thereof, said teeth being struck in longitudinally extending generally parallel rows, the teeth in alternate rows being struck such that the slots left thereby extend from the teeth in like longitudinal directions, the teeth in the rows between said alternate rows being struck to form a plurality of longitudinally spaced sets of two teeth each, the teeth in each set being struck such that a continuous slot is left in said plate between said teeth with the portions of the slot left by each tooth extending therefrom toward the opposite tooth, successive teeth in said alternate rows thereof being spaced longitudinally one from the other and relative to said sets of teeth in next adjacent rows such that each successive tooth lies substantially meDially between the pair of teeth forming a set thereof in a next laterally adjacent row of teeth whereby the number of teeth in each said alternate row is substantially one-half the number of teeth in each said next adjacent row, the teeth in said alternate rows thereof being longer in length than the teeth in the next adjacent rows with the latter teeth being approximately 0.5 to 0.7 the length of the former teeth.
Claim 2
Dependent Claim

A connector plate for joining wooden members one to the other comprising: an elongated sheet metal plate, a plurality of elongated naillike teeth struck from said plate to project to one side thereof, said teeth being struck in longitudinally extending generally parallel rows, the teeth in alternate rows being struck such that the slots left thereby extend from the teeth in like longitudinal directions, the teeth in the rows between said alternate rows being struck to form a plurality of longitudinally spaced sets of two teeth each, the teeth in each set being struck such that a continuous slot is left in said plate between said teeth with the portions of the slot left by each tooth extending therefrom toward the opposite tooth, successive teeth in said alternate rows thereof being spaced longitudinally one from the other and relative to said sets of teeth in next adjacent rows such that each successive tooth lies substantially meDially between the pair of teeth forming a set thereof in a next laterally adjacent row of teeth whereby the number of teeth in each said alternate row is substantially one-half the number of teeth in each said next adjacent row, the teeth in said alternate rows thereof being longer in length than the teeth in the next adjacent rows with the latter teeth being approximately 0.5 to 0.7 the length of the former teeth.
Claim 3
Dependent Claim
31 words
A connector plate according to claim 1 wherein the pair of teeth in each set thereof have oppositely scarfed tips to provide a clinching action upon embedment into the wooden members.
Claim 4
Dependent Claim
18 words
A connector plate according to claim 2 wherein the teeth in said alternate rows have chisel pointed tips.
Claim 5
Dependent Claim
20 words
A connector plate according to claim 1 wherein said plate is formed of 18 U.S. Standard Gauge galvanized sheet metal.
Claim 6
Dependent Claim
35 words
A connector plate according to claim 1 wherein the pair of teeth in each set thereof are twisted about their respective long axes to increase their resistance to withdrawal upon embedment into the wooden members.
Claim 7
Dependent Claim
68 words
A connector plate according to claim 1 wherein the pair of teeth in each set thereof have oppositely scarfed tips to provide a clinching action upon embedment into the wooden members, said pair of teeth in each thereof being twisted about their respective long axes to increase their resistance to withdrawal upon embedment into the wooden members, the teeth in said alternate rows thereof having chisel pointed tips.
Claim 8
Dependent Claim
28 words
A connector plate according to claim 1 wherein said teeth are distributed throughout said plate to provide a tooth density of at least six teeth per square inch.
