| 摘要 | A power driven mechanism is disclosed herein for feeding a length of wire about an object to be tied and for twisting the wire into a closure about the object. The mechanism includes a motor for driving a pair of arms for positioning the wire length and for twisting the wire into securement. The motor also drives a cutting mechanism for severing the wire. Reduction gearing, cams and cam followers and pivotal linkage operably interconnect the mechanism so as to provide a predetermined operating sequence. | ||||||
| 权利要求 | 1. A portable power driven wire tying mechanism comprising the combination of: a housing; motor means carried in said housing; a pair of jaw members longitudinally movable to extend and retract with respect to said housing; linkage means operably connecting said jaw members to said motor means for automatic reciprocating movement thereof; a source of wire carried on said housing and having a portion thereof trained about one of said jaw members adapted to engage the other of said jaw members when in their extended position; and means coupled to said motor means via said linkage means for twisting said wire portion when said jaw members are retracted and severing said twisted wire portion. 2. The invention as defined in claim 1 including means interconnecting said pair of jaw members for adjusting the opening between their opposing ends. 3. The invention as defined in claim 2 wherein said last mentioned means comprises a turnbuckle. 4. The invention as defined in claim 2 including a second housing rotatably carried on said first housing and enclosing said jaw members in their retracted position. 5. The invention as defined in claim 4 wherein said linkage means includes cams and cam followers operably coupled to said jaw members for time sequencing the operation of wire feeding, wire twisting and wIre cutting. 6. The invention as defined in claim 5 including a pair of handles for manually holding said mechanism wherein one handle is grasped by each hand of the operator. 7. The invention as defined in claim 6 wherein said jaw members are pivotal carried on a yoke and roller cams engage with shaped edges of said jaw members to open and close their opposing ends responsive to said timing means. 8. The invention as defined in claim 7 wherein said jaw members are articulated arms having a cutting assembly carried on a selected one of their opposing ends. 9. The invention as defined in claim 8 including a bearing means disposed between said first and second housings. 10. The invention as defined in claim 9 including a third pivotal arm operably in response to said jaw members for feeding wire from a spool to said jaw members. |
