Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 223 words
A tool for affixing a connector around two overlying portions of a strap surrounding a package or container, comprising, in combination, a frame, first manually operable means mounted on said frame for temporarily clamping a first one of two spaced strap portions on said frame, second manually operable means mounted on said frame engageable with the other of said strap portions for tensioning the strap around a package or container, with the two strap portions in overlying position, and third manually operable means mounted on said frame for sealing a connector element about the strap overlying portions, said firstnamed means including a pad carried by said frame and a clamping head movably mounted on said frame for cooperation with said pad, said second means including a tensioning drum rotatably mounted on said frame and in alignment with said pad and clamping head, said third means including an assembly of anvils and of openable and closable sealing jaws carried by said frame intermediate said pad and tensioning drum and in alignment therewith, and fourth means mounted on said frame for cutting the strap, said fourth means being mounted intermediate said sealing jaws and said tensioning drum and being in alignment therewith, said fourth means being drivingly connected to said first means for cutting operation upon release of said first one of said strap portions.
Claim 2
Dependent Claim 223 words
A tool for affixing a connector around two overlying portions of a strap surrounding a package or container, comprising, in combination, a frame, first manually operable means mounted on said frame for temporarily clamping a first one of two spaced strap portions on said frame, second manually operable means mounted on said frame engageable with the other of said strap portions for tensioning the strap around a package or container, with the two strap portions in overlying position, and third manually operable means mounted on said frame for sealing a connector element about the strap overlying portions, said firstnamed means including a pad carried by said frame and a clamping head movably mounted on said frame for cooperation with said pad, said second means including a tensioning drum rotatably mounted on said frame and in alignment with said pad and clamping head, said third means including an assembly of anvils and of openable and closable sealing jaws carried by said frame intermediate said pad and tensioning drum and in alignment therewith, and fourth means mounted on said frame for cutting the strap, said fourth means being mounted intermediate said sealing jaws and said tensioning drum and being in alignment therewith, said fourth means being drivingly connected to said first means for cutting operation upon release of said first one of said strap portions.
Claim 3
Dependent Claim 97 words
A tool as claimed in claim 1, wherein said first means include a tool holding member pivoted at one end to said frame for movement between open and closed position, a manually operable fifth means to latch said tool holding member in closed position, first linkage connecting said clamping head to said tool holding member, for clamping movement of said clamping head upon closinG movement of said tool holding member and second linkage connecting said fourth means to said tool holding member for cutting operation of said fourth means upon opening movement of said tool holding member.
Claim 4
Dependent Claim 64 words
A tool as claimed in claim 1, wherein said fourth means include a cutter blade secured to said frame and a cutting member movably mounted on said frame adjacent said cutting blade and operatively connected to said tool holding member by said second linkage, said cutting member having a lateral notch for receiving a strap portion and being spring pressed against said cutter blade.
Claim 5
Dependent Claim 142 words
A tool as claimed in claim 1, wherein said third manually operable means further include a support slidably mounted in said frame, a lever handle rotatably mounted on said support, a crank shaft rotatably mounted on said support and keyed to said lever handle, said anvils carried by said support, said sealing jaws including two sets of opposed sealing jaws, a pair of toggle lever mechanisms each including one set of said sealing jaws and connected to said support and to said crank shaft, a cam secured to said crank shaft, and a reaction member carried by said frame and engaging said cam, so arranged that rotation of said handle in a direction to close said sealing jaws rotate said cam which produces slidable movement of said support towards said strap overlying portions by reaction of said cam against said reaction member.
Claim 6
Dependent Claim 15 words
A tool as claimed in claim 1, wherein said pad is pivoted to said frame.
Claim 7
Dependent Claim 84 words
A tool as claimed in claim 5, wherein said toggle lever mechanisms operate in a plane perpendicular to the axis of said crank shaft, and including a common connecting rod, connected to both said toggle lever mechanisms and to said crank shaft by means of universal joints, the connection of said connecting rod to said toggle lever mechanisms being guided by said support for lateral and longitudinal movement, whereby one set of sealing jaws effect closing movement before the other set of sealing jaws.
Claim 8
Dependent Claim 32 words
A tool as claimed in claim 2, wherein said first linkage is adjustable to change the spacing between said clamping head and said pad in the clamped position of said clamping head.
Claim 9
Dependent Claim 142 words
A tool as claimed in claim 1, further including a connector magazine formed by said frame for holding a plurality of connectors arranged in a row, said magazine having a free edge, and plunger means drivingly connected to said third means to engage the endmost connector of the row and move it to a position for sealing the strap overlying portions, said plunger means including a feeding arm pivotally connected to said frame, a plunger rod pivotally connected to the free end of said feeding arm, spring loaded for pivoting movement and slidably bearing against the free edge of said magazine to be in alignment with the endmost connector, a cam arm secured to said feeding arm and having a cam edge and an eccentrically mounted member secured to said crankshaft cam and engaging said cam edge to pivot said feeding arm.
