| 摘要 | A hand tool is adapted for bending wire manually and includes an elongate bar having a wire engaging head secured thereto at one end and another, similar, wire engaging head disposed intermediate the ends of the bar. Two such identical tools are employed to effect the desired bend in the wire. Each head on each tool projects transversely from the bar and has a T-shaped channel which extends parallel to the axis of the bar. In use the tools are placed, head end to head end, parallel to the wire, with the wire received in the T-shaped slots. With the adjacent head ends of the tools in abutment, the distal ends of the tools then are pivoted transversely toward each other to effect the desired bend in the wire at a location between the proximate ends of the tools. During bending, the proximate ends of the tools bear against each other to provide leverage. | ||||||
| 权利要求 | 1. A hand tool for use in bending a wire comprising: an elongate bar; a head secured to one end of said bar having a portion thereof projecting transversely of the longitudinal dimension of said bar; said projecting portion having a channel formed therethrough and extending in a direction parallel to that of said elongate bar; and a pair of lugs formed integrally with said projecting portion of said head, said lugs extending longitudinally along said channel to define a restricted opening in said channel and paralleling said bar and to define said channel in a T-shaped cross-sectional configuration. 2. A hand tool as defined in claim 1 wherein said end head is defined by outer side wall surfaces on opposite sides thereof further further comprising: said sidewalls surfaces being tapered toward said end of said tool. 3. A hand tool as defined in claim 2 further comprising: at least portions of said sidewall surfaces being formed from a material harder than the remaining portions of said end head. 4. A hand tool as defined in claim 2 further comprising: said channel being formed so that the innermost region thereof is disposed in relation to said elongate bar so that when said wire is inserted into said channel, said wire is parallel to said bar and is spaced transversely thereof but in proximity thereto whereby the user may grip both the elongate bar and the engaged wire. 5. A hand tool as defined in claim 1 further comprising: an intermediate head mounted to said bar intermediate its ends, said intermediate head projecting transversely of the longitudinal dimension of said bar and in the same direction as said end head, said intermediate head having a channel of identical configuration to that formed in said end head, said channel in said intermediate head being aligned longitudinally with said channel in said end head. 6. A hand tool as defined in claim 5 further comprising: said intermediate head being mounted to said bar for adjustable movement along the length of said bar; and means for securing said intermediate head to said bar in a selected longitudinal position thereon. 7. Manually operable tool means as defined in claim 1 further comprising a pair of such hand tools. 8. A hand tool as defined in claim 6 further comprising: means for precluding rotation of said intermediate head about said bar. 9. A hand tool as defined in claim 8 wherein said means for precluding rotation of said intermediate head about said bar comprises: a slot formed longitudinally along the underside of said bar; and a pin secured to said intermediate head and projecting radially inwardly thereof, said pin being received within said longitudinal slot in said bar. 10. A hand tool as defined in claim 9 wherein said means for securing said intermediate head to said bar in selected longitudinal positions thereon comprises: said bar being formed with a plurality of transverse notches disposed in longitudinally spaced relation along said bar; and a set screw threaded through said intermediate head, said set screw having a pin projecting from the inner end thereoF for selective engagement with one of said notches. |
