| 摘要 | A pliers-like hand operated innovative tool which in use has proved effective when the user is called upon to take up slack and tighten sagging post-supported fence wires (in old or new fences) or alternatively, for crimping and tightening line wires whether woven with vertical stays, plain and smooth or of barbed wire in construction. Two lever or handle units, that is, Ushaped handle-equipped units are provided with opposed confronting shaft-like rod members uniquely and hingedly joined. The primary rod member has forwardly projecting longitudinally spaced brackets, each bracket comprising a projecting shank carrying a V-shaped adapter. The prongs or fingers of the adapter straddle the wire and a portion of the wire is firmly nested, seated and held in the anvil-like crotch portion. Six, more or less, brackets accommodate a stretch of the wire which is to be bent and suitably crimped in a manner to shorten the wire. The rod member of the second and companion unit provides a rocker shaft equipped with crimping or kinking fingers which are coordinated to coact with the adapters. By holding one handle or lever and actuating the other one relative thereto the desired multiple crimping result is achieved. | ||||||
| 权利要求 | 1. For use when taking the slack out of and tightening a supported fence wire or the like, a manually usable wire crimping and kinking tool comprising: a primary handle unit embodying an elongated rigid rod constituting a shaft-like body member and provided with a pair of longitudinally spaced integral aligned collar-like bearings, also provided with a plurality of integrAl brackets embodying wire positioning adapters, each adapter having an anvil-like crotch in which a portion of the bendable wire can be firmly and retentively seated preparatory to crimping, said handle unit further provided with handle means capable of being grasped and operatively held in one hand of the user, and a secondary handle unit complemental to said primary unit and embodying a rod opposed to, paralleling said first named rod, providing a rocker-shaft and having terminal end portions journaled for operation in said bearings, said rocker-shaft having handle means coacting with said first named handle means and swingable with the other hand of the user relative thereto, and also having a plurality of rigid lateral wire engaging fingers associatively aligned and cooperable with said adapters and, when properly actuated, serving to forcibly clench seated portions of said wire in a manner to uniformly bend and crimp the same. 2. The tool defined in claim 1, and wherein each adapter is substantially V-shaped in side elevation, the crotch having a shank and said shank being integrally joined with and positioned laterally to a coordinating peripheral surface of said rod having said bearing thereon. 3. The tool defined in claim 1, and wherein each adapter is substantially V-shaped in side elevation, the crotch having a shank and said shank being integrally joined with and positioned laterally to a coordinating peripheral surface of said rod having said bearings thereon, each adapter having outwardly diverging prongs of a length to initially pilot and guide the respective brackets into ready-to-function wire placement position prior to initiating the step of actuating the handle means of the secondary unit. 4. The kinking tool defined in claim 1, and wherein each handle means is substantially U-shaped in plan. 5. The kinking tool defined in claim 1, and wherein each handle means is substantially U-shaped in plan, the U-portion of the first named handle means being larger in size than the corresponding U-portion of the second mentioned handle means. 6. The tool defined in claim 3, and wherein each handle means is U-shaped in plan and embodies coplanar legs united at corresponding inward ends by a connecting bight portion, the outward ends of the legs remote from the bight portion being operatively joined with the respectively associated first and second named rods. 7. The tool defined in claim 3, and wherein each handle means is U-shaped in plan and embodies coplanar legs united at corresponding inward ends by a connecting bight portion, the outward ends of the legs remote from the bight portion being operatively joined with the respectively associated first and second named rods, the U-portion of the second named handle means being smaller in size than and being surrounded by the larger U-portion of said first named handle means when the respective handle means are in a common plane. 8. For use when taking the slack out of and tightening a supported fence wire or the like, a manually usable wire crimping and kinking tool comprising: a primary handle unit embodying an elongated rigid rod constituting a shaft-like body member and provided with a pair of longitudinally spaced integral aligned collar-like bearings, also provided with a plurality of integral brackets embodying wire positioning adapters, each adapter being V-shaped in side elevation and providing an anvil-like wire seating crotch portion, each crotch portion embodying a vertex which is integrally united with a shank, said shank being lateral to and integrally joined to a given coordinating peripheral surface of the rod, said unit also embodying a U-shaped levering and operating handle, and a secondary handle unit complemental to said primary unit and embodying a rod opposed to, paralleling said first named rod, providing a rocker-shaft and having terminal end portions journaled for operation in said bearings, said rocker-shaft having handle means coacting with said firsT named handle means and swingable with the other hand of the user relative thereto, and also having a plurality of rigid lateral wire engaging fingers associatively aligned and cooperable with said adapters and, when properly actuated, serving to forcibly clench seated portions of said wire in a manner to uniformly bend and crimp the same. |
