Abstract

Abstract A device for making a composite structural member of the type made up of a plurality of superimposed structural elements secured together by staples includes a guide block disposed above and a receiving block disposed beneath said superimposed structural elements. The guide block has a plurality of elongated grooves having spaced openings whereby staples pass through said openings and through said superimposed structural elements to engage grooves in said receiving member which turn the ends of the staples laterally to thereby secure the staple.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 313 words
A device for manufacturing a composite structural member of the type made up of a plurality of superimposed structural elements secured together by staples comprising a guide block having an upper surface, a plurality of individual rails projecting from said upper surface, said rails being arranged in pairs with the two individual rails constituting a pair being separated from one another by a first elongated space, said first elongated space and the pair of rails defining said first elongated space forming an elongated groove on said top surface of said guide block, said pairs of rails being separated from each other by a second elongated space parallel to said first elongated space, means disposed along the bottom of said elongated groove defining a plurality of spaced openings passing completely through said guide block, said guide block being adapted to be disposed over said plurality of superimposed structural elements, a receiving block adapted to be disposed beneath said plurality of superimposed structural elements, said receiving block having a plurality of grooves formed therein, said grooves being arranged in pairs with the two individual grooves constituting a pair having a combined width substantially corresponding to the width of said openings in said guide block, said pairs of grooves being separated from one another a distance substantially corresponding to the distance between said elongated grooves on said guide block, said receiving block being disposed relative to said guide block such that said elongated grooves on said guide block generally overlie said pairs of grooves on said receiving block, whereby staples are adapted to be passed through said spaced openings in said elongated grooves in said guide block, pass through said superimposed structural elements, and engage said grooves in said receiving block such that upon engaging said grooves, the staples are turned laterally to thereby close the staple and secure together said plurality of superimposed structural elements.
Claim 2
Independent Claim 313 words
A device for manufacturing a composite structural member of the type made up of a plurality of superimposed structural elements secured together by staples comprising a guide block having an upper surface, a plurality of individual rails projecting from said upper surface, said rails being arranged in pairs with the two individual rails constituting a pair being separated from one another by a first elongated space, said first elongated space and the pair of rails defining said first elongated space forming an elongated groove on said top surface of said guide block, said pairs of rails being separated from each other by a second elongated space parallel to said first elongated space, means disposed along the bottom of said elongated groove defining a plurality of spaced openings passing completely through said guide block, said guide block being adapted to be disposed over said plurality of superimposed structural elements, a receiving block adapted to be disposed beneath said plurality of superimposed structural elements, said receiving block having a plurality of grooves formed therein, said grooves being arranged in pairs with the two individual grooves constituting a pair having a combined width substantially corresponding to the width of said openings in said guide block, said pairs of grooves being separated from one another a distance substantially corresponding to the distance between said elongated grooves on said guide block, said receiving block being disposed relative to said guide block such that said elongated grooves on said guide block generally overlie said pairs of grooves on said receiving block, whereby staples are adapted to be passed through said spaced openings in said elongated grooves in said guide block, pass through said superimposed structural elements, and engage said grooves in said receiving block such that upon engaging said grooves, the staples are turned laterally to thereby close the staple and secure together said plurality of superimposed structural elements.
Claim 3
Dependent Claim 28 words
A device according to claim 1 wherein said spaced openings in said elongated groove have a maximum width substantially corresponding to the width of said first elongated space.
Claim 4
Dependent Claim 19 words
A device according to claim 1 wherein said openings in each elongated slot are equally spaced from one another.
Claim 5
Dependent Claim 40 words
A device according to claim 3, wherein the openings in one of said elongated grooves are arranged in staggered array relative to the openings in an adjacent elongated groove, such that the applied staples are evenly spaced in two directions.
