Abstract
Abstract 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.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
113 words
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.
Claim 2
Dependent Claim
113 words
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.
Claim 3
Dependent Claim
23 words
The invention as defined in claim 1 including means interconnecting said pair of jaw members for adjusting the opening between their opposing ends.
Claim 4
Dependent Claim
