Assembly jig for the nailing of wood frame members

Claim 2

An assembly jig and transport means therefor for the nailing of wood frame structures that comprise a plurality of cross pieces arranged in parallel spaced relationship and a plurality of top pieces arranged crosswise to and on top of said cross pieces, said jig comprising a horizontally oriented rigid supporting frame, at least one cross piece supporting member laterally adjustably mounted upon said supporting frame, means for positioning said top pieces upon said supported cross pieces, conveying means attached to said supporting frame for moving said frame from a loading position to a position beneath a nailing machine structure to permit said top pieces and cross pieces to be nailed together and to a discharging position downstream of said machine, and means for shifting the position of said cross piece supporting member relative to said supporting frame to cause the nailed assembly to be dropped vertically out of said jig at said discharging position.

Claim 3

An assembly jig and transport means therefor for the nailing of wood frame structures as set forth in claim 1 wherein said cross piece supporting member is pivotally mounted at the upper edge thereof to said supporting frame, said cross piece supporting member being positioned so as to engage a cam to cause the supporting member to pivot in its mounting to release said nailed assembly.

Claim 4

An assembly jig and transport means therefor for the nailing of wood frame structures as set forth in claim 2 wherein said cross piece supporting member includes a cylindrical rod extending along its uppermost edge, a backing plate depending from said rod and adapted to engage the ends of said cross pieces, and a supporting surface extending at right angles to said backing plate to support the lowermost surfaces of said cross pieces.

Claim 5

An assembly jig and transport means therefor for the nailing of wood frame structures as set forth in claim 3 wherein said cylindrical rod is provided with a cam follower mounted in offset relationship to the longitudinal axis of the rod, said cam being positioned to be engaged by said cam follower to rotate said rod about its said axis during discharge of said nailed assembly.

Claim 6

An Assembly jig and transport means therefor for the nailing of wood frame structures as set forth in claim 1 including a back bar extending transversely to said cross piece supporting member, and means for slidably adjustably mounting said back bar to said supporting frame, the distance between said back bar and a parallel portion of said supporting frame determining the length of the top pieces in the wood frame structure to be nailed with the outer pair of said cross pieces being positioned parallel to and in engagement with said back bar and said parallel portion of the supporting frame.

Claim 7

An assembly jig and transport means therefor for the nailing of wood frame structures as set forth in claim 5 including a plurality of guide pieces adjustably mounted upon said back bar and upon said parallel portion of the supporting frame for contact with and alignment of said top pieces of the wood frame structure.

Claim 8

An assembly jig and transport means therefor for the nailing of wood frame structures as set forth in claim 1 including control means for said conveying means operable to stop the movement of said supporting frame as each of said cross pieces are received directly beneath the mailing machine structure and when said nailed assembly is dropped from said jig.

Claim 9

An assembly jig and transport means therefor for the nailing of wood frame structures as set forth in claim 7 including a switch located beneath said supporting frame at said discharge position for actuation by said nailed assembly when it is dropped, and control means for reversing said conveying means to carry said supporting frame back to said loading position, said last named control means being actuated by said switch.

Claim 10

An assembly jig and transport means therefor for the nailing of wood frame structures that comprise a plurality of cross pieces arranged in parallel spaced relationship and a plurality of top pieces arranged crosswise to and on top of said cross pieces, said jig comprising a horizontally oriented supporting frame, said supporting frame including a first cross frame member and a pair of side frame members rigidly interconnected in parallel spaced relationship by said first cross frame member, a pair of cross piece supporting members laterally adjustably mounted upon said first cross frame member in spaced relationship and extending parallel to said side frame members, conveying means attached to said supporting frame for moving said frame from a loading position to a position beneath a nailing machine structure to permit said top pieces and cross pieces to be nailed together and to a discharging position downstream of said nailing machine, and means on said jig arranged to cooperate with a fixed abutment for shifting each of said cross piece supporting members away from the other supporting member to cause the nailed assembly to be dropped vertically out of said jig at said discharging position.

Claim 11

An assembly jig and transport means therefor for the nailing of wood frame structures that comprise a plurality of cross pieces arranged in parallel spaced relationship and a plurality of top pieces arranged crosswise to and on top of said cross pieces, said jig comprising a horizontally oriented supporting frame, said supporting frame including a first cross frame member and a pair of side frame members rigidly interconnected in parallel spaced relationship by said first cross frame member, a pair of cross piece supporting members laterally adjustably mounted upon said first cross frame member in spaced relationship and extending parallel to said side frame members, conveying means attached to said supporting frame for moving said frame from a loading position to a position beneath a nailing machine structure to permit said top pieces and cross pieces to be nailed together and to a discharging position downstream of said nailing machine, and means on said jig arranged to cooperate with a fixed abutment for shifting each of said cross piece supporting members away from the other supporting member to cause the nailed assembly to be dropped vertically out of said jig at said discharging position.

Claim 12

An assembly jig and transport means therefor for the nailing of wood frame structures as set forth in claim 9 wherein said cross piece supporting members each include a cylindrical rod, a backing plate extending downwardly from said rod, a backing plate extending downwardly from said rod and being adapted to engage the ends of said cross pieces, and a supporting surface extending at right angles to said backing plate to supportingly engage said cross pieces; said rods being arranged to engage a fixed cam when the supporting frame reaches said discharging position to cause the rods to rotate about their longitudinal axes to thereby move said support surfaces outwardly and drop said nailed assembly.

Claim 13

An assembly jig and transport means therefor for the nailing of wood frame structures as set forth in claim 10 including cam followers mounted upon said rods at the ends thereof for engagement with said cam, said cam followers being mounted in laterally offset relationship to said rods, and a second cross frame member connected between said side frame members for rotatably supporting said rods.

Claim 14

An assembly jig and transport means therefor for the nailing of wood frame structures as set forth in claim 9 including a back bar positioned transversely to said cross piece supporting members, means for adjustably mounting said back bar to said side frame members in parallel relationship with said first cross frame member, the outermost pair of cross pieces being arranged to lie adjacent to said back bar and to said first cross frame member with said top pieces extending from said first cross frame member to said back bar, the outer pair of top pieces being arranged for parallel engagement with said cross piece supporting members.

Claim 15

An assembly jig and transport means therefor for the nailing of wood frame structures as set forth in claim 12 including a plurality of guide pieces adjustably mounted upon said back bar and upon said first cross frame member for contact with and alignment of the edges of said top pieces of the wood frame structure.
