Abstract
Abstract A manually operated semi-automatic tool for tying wire bundles with a plastic cable tie and cutting the tie a predetermined tension by the actuation of a trigger. The tool is of gunlike shape having a nose section of minimum dimension especially adopted for miniature harnessing. The mechanical components are especially designed to be contained in a housing shaped for more effective miniature harnessing operations common to modern electronic packaging.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
247 words
A device for applying predetermined tension to a cable tie and automatically cutting the cable tie at said tension comprising: a longitudinal barrel having a front barrel portion and a rear barrel portion; a handle extending transversely from said barrel; a trigger pivotally attached to said barrel and extending transversely therefrom in spaced relation to said handle; first means mounted slidably in said barrel and adapted to grip a cable tie received in said barrel; cylinder means reciprocatingly slidAbly disposed in said rear barrel portion and connected to said first means so that movement of said cylinder means causes corresponding movement of said first means; second means slidably disposed in said cylinder means and resiliently coupled thereto so that movement of said second means selectively causes movement of said cylinder means; third means coupling said trigger to said second means, wherein actuation of said trigger towards said handle causes longitudinal rearward movement of said second means and said cylinder means and gripping of said cable tie to apply tension thereto as said cylinder means moves rearward; and an articulated assembly in said front barrel portion having cutter means thereon and coacting with said third means, said third means being movably responsive to the pressure exerted thereon by said cylinder means whereby rearward motion of said first means is arrested when the said tension is caused in the cable tie whereupon said third means activates said articulated assembly and said cutter means effecting cutting of said cable tie.
Claim 2
Independent Claim
247 words
A device for applying predetermined tension to a cable tie and automatically cutting the cable tie at said tension comprising: a longitudinal barrel having a front barrel portion and a rear barrel portion; a handle extending transversely from said barrel; a trigger pivotally attached to said barrel and extending transversely therefrom in spaced relation to said handle; first means mounted slidably in said barrel and adapted to grip a cable tie received in said barrel; cylinder means reciprocatingly slidAbly disposed in said rear barrel portion and connected to said first means so that movement of said cylinder means causes corresponding movement of said first means; second means slidably disposed in said cylinder means and resiliently coupled thereto so that movement of said second means selectively causes movement of said cylinder means; third means coupling said trigger to said second means, wherein actuation of said trigger towards said handle causes longitudinal rearward movement of said second means and said cylinder means and gripping of said cable tie to apply tension thereto as said cylinder means moves rearward; and an articulated assembly in said front barrel portion having cutter means thereon and coacting with said third means, said third means being movably responsive to the pressure exerted thereon by said cylinder means whereby rearward motion of said first means is arrested when the said tension is caused in the cable tie whereupon said third means activates said articulated assembly and said cutter means effecting cutting of said cable tie.
Claim 3
Dependent Claim
35 words
A device as defined in claim 1 wherein said articulated assembly includes a pivoted first portion to which said cutter means is attached, said cutter means being adapted to move transversely against the cable tie.
Claim 4
Dependent Claim
71 words
A device as defined in claim 1 wherein said third means includes a pivoted link movable between said second means and said articulated assembly, said second means abutting said pivoted link and being spring biased to a position retaining the pivoted link against rotation until said tension is attained whereby the further movement of said second means is arrested permitting rotation of said pivoted link in response to further trigger actuation.
Claim 5
Dependent Claim
30 words
A device as defined in claim 3 wherein said second means is a hollow piston within which is longitudinally disposed spring means resiliently coupling said piston to said cylinder means.
Claim 6
Dependent Claim
27 words
A device as defined in claim 4 further comprising means cooperative with said spring means for varying the resilient coupling between said piston and said cylinder means.
Claim 7
Dependent Claim
40 words
A device as defined in claim 1 further comprising spring means connecting said articulated assembly to said cylinder means to selectively bias said articulated assembly to a first position out of engagement with a cable tie received in said barrel.
