Abstract
Abstract An improved connector plate is provided for securing abutting wooden truss members to one another. The connector plate comprises a metal sheet and at least one pair of prongs integrally formed with the sheet by punching the prongs outwardly from the sheet. The prongs form an elongated slot in the sheet having a reduced central portion wherein the prongs break apart from each other at the reduced central portion of the slot when the prongs are punched to thereby form a relatively dull point for each prong.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
138 words
A connector plate comprising: a metal sheet, and at least one pair of prongs integrally formed with said sheet by punching said prongs from said sheet so that said prongs are substantially parallel to each other and substantially perpendicular from said plate and so that the displacement of said prongs forms an elongated slot in said sheet, said slot having a tapering reduced central portion, and wherein said prongs have tapering necked-down, torn tips formed by breaking apart from each other at the narrowest point of the tapering reduced central portion of the slot when the prongs are punched from the sheet to thereby form a dull point on each prong, whereby said connector plate may be handled without injury and whereby said connector plate will firmly attach to a wooden truss element for long periods of time.
Claim 2
Dependent Claim
138 words
A connector plate comprising: a metal sheet, and at least one pair of prongs integrally formed with said sheet by punching said prongs from said sheet so that said prongs are substantially parallel to each other and substantially perpendicular from said plate and so that the displacement of said prongs forms an elongated slot in said sheet, said slot having a tapering reduced central portion, and wherein said prongs have tapering necked-down, torn tips formed by breaking apart from each other at the narrowest point of the tapering reduced central portion of the slot when the prongs are punched from the sheet to thereby form a dull point on each prong, whereby said connector plate may be handled without injury and whereby said connector plate will firmly attach to a wooden truss element for long periods of time.
Claim 3
Dependent Claim
59 words
The invention as defined in claim 1 wherein said prongs are formed by forcing a punch having a reduced area portion on the portion of the punch which first contacts the sheet through the metal sheet, said reduced area portion of the punch being substantially flat and corresponding in shape to the reduced and central portion of the slot.
Claim 4
Dependent Claim
15 words
The invention as defined in claim 1 wherein said prongs are V-shaped in cross section.
