Abstract
Abstract The fabrication system comprises a conveyor operable to advance a jig table carrying wooden frame members positioned thereon forming a truss, panel or the like to successively locate the longitudinally spaced butt joints thereof below a press platen for embedment of nailplates of the type having a plurality of teeth stuck therefrom into the butt joints. The conveyor and press are controlled via a circuit including an index wheel actuated switch which automatically and sequentially stops the conveyor when successive butt joints are located below the press, actuates the press to embed the nailplates, and restarts the conveyor to advance the jig table to locate successive butt joints below the press. The index wheel is driven from the conveyor and has a plurality of recesses spaced a predetermined distance one from the other about the periphery thereof representing a predetermined distance of conveyor advance. A plurality of magnetic pins are inserted in selected recesses of the wheel and project to successively actuate the switch controlling the conveyor and press. The selectivity of the spacing between adjacent pins permits fabrication of trusses, panels or the like of different sizes and types.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
181 words
A fabrication system for successively embedding Connector plates in the spaced butt joints of prepositioned wooden framing members forming trusses or the like comprising means for supporting the wooden frame members, a press adjacent said support means for embedding the connector plates into the butt joints of the members, means for mounting said support means and said press for relative movement with said press defining a press position at each juxtaposition of said press and the butt joints of the members carried by said support means, means providing for relative movement between said support means and said press to locate successive butt joints of the wooden members in successive press positions for embedment of the connector plates into the wooden members at the butt joints thereof, and means arranged in controlling relation to said moving means including index means operable in response to relative movement of said support means and said press successive distances equal to the distances between consecutive butt joints to successively actuate said press and embed the connector plates into the wooden members at the butt joints thereof.
Claim 2
Dependent Claim
181 words
A fabrication system for successively embedding Connector plates in the spaced butt joints of prepositioned wooden framing members forming trusses or the like comprising means for supporting the wooden frame members, a press adjacent said support means for embedding the connector plates into the butt joints of the members, means for mounting said support means and said press for relative movement with said press defining a press position at each juxtaposition of said press and the butt joints of the members carried by said support means, means providing for relative movement between said support means and said press to locate successive butt joints of the wooden members in successive press positions for embedment of the connector plates into the wooden members at the butt joints thereof, and means arranged in controlling relation to said moving means including index means operable in response to relative movement of said support means and said press successive distances equal to the distances between consecutive butt joints to successively actuate said press and embed the connector plates into the wooden members at the butt joints thereof.
Claim 3
Dependent Claim
64 words
A fabrication system according to claim 1 wherein said control means includes switch means and said index means includes means carrying a plurality of spaced switch-actuating elements, the spacing between adjacent actuating elements being proportional to the predetermined spacing between the butt joints, and means providing for relative movement between said switch means and said carrying means for successive actuation of said switch means.
Claim 4
Dependent Claim
44 words
A fabrication system according to claim 2 wherein said carrying means includes a plurality of mounting positions for said elements, means releasably retaining said elements in said mounting positions, said elements being movable between mounting positions to selectively vary the spacing between adjacent elements.
Claim 5
Dependent Claim
51 words
A fabrication system according to claim 3 wherein adjacent mounting positions are spaced a predetermined distance on said carrying means proportional to a predetermined distance of relative movement between said press and said support means, the spacing between adjacent elements being a whole multiple of the spacing between the associated positions.
Claim 6
Dependent Claim
73 words
A fabrication system according to claim 1 wherein said control means includes switch means and said index means includes a rotatable wheel, said wheel mounting a plurality of spaced-actuating pins about the periphery thereof, the spacing of successive adjacent pins one from the other being proportional to the successive predetermined spacing between the joints, and means drivingly connecting said wheel to said moving means for rotating said wheel to successively actuate said switch.
Claim 7
Dependent Claim
55 words
A fabrication system according to claim 5 wherein said wheel has a plurality of spaced recesses opening through a sideface and adjacent the periphery thereof for receiving said pins, and magnetic means for releasably retaining said pins in said recesses, said pins being movable between the recesses to selectively vary the spacing between adjacent pins.
Claim 8
Dependent Claim
33 words
A fabrication system according to claim 1 wherein said index means is arranged in controlling relation to said moving means to successively stop the relative movement between said press and said support means.
Claim 9
Dependent Claim
52 words
A fabrication system according to claim 7 wherein said moving means includes fluid motor means and a fluid circuit therefor having valve means controlling said fluid motor means, said index means including switch means arranged in controlling relation to said valve means to shift the latter and stop said fluid motor means.
Claim 10
Dependent Claim
97 words
A fabrication system according to claim 1 wherein said press includes a press platen and at least one fluid-actuated cylinder operable to move said platen toward and away from the joints, said control means including a fluid control circuit having electrically actuated valve means operably connected with said cylinder, an electrical circuit arranged in controlling relation to said valve meanS, and switch means in said electrical circuit, said indexing means being operable to actuate said switch means to energize said electrical circuit and shift said valve to move the press platen toward and away from the joint.
Claim 11
Dependent Claim
120 words
A fabrication system according to claim 7 wherein said moving means includes a fluid motor and said press includes a press platen and at least one fluid actuated cylinder operable to move said platen toward and away from the joints, said control means including a fluid control circuit having electrically actuated valves operably connected with said fluid motor and said cylinder, an electrical circuit arranged in controlling relation to said valves, and switch means in said electrical circuit, said indexing means being operable to actuate said switch means to energize said electrical circuit to shift said valves to stop the relative movement of said press and said support means and move the press platen toward and away from the joint.
