Wire knotting machine

A wire knotting machine for securing a first wire to a second wire extending at right angles to the first, said first wire being closely adjacent the second, and having a standing portion extending in one direction from said second wire and a relatively short end portion extending oppositely from said second wire, said machine comprising:

• a. a driver member rotatable coaxially with said second wire and having an extension parallel but eccentric to its axis and normally underlying said first wire at the side thereof opposite from said second wire,
• b. means operable to turn said driver member with an angularly reciprocal motion, whereby during the motion thereof in one direction, the extension thereof engages the end portion of said first wire and bends it around said second wire toward its own standing portion, and
• c. a fixed anvil having an arcuate concavity which has an axis of curvature generally parallel to the first wire, and curved about said first wire standing portion, in spaced apart relation therefrom, at the side thereof opposite to that toward which the end portion thereof is moved by said driver member, said anvil being disposed so as to be engaged by the part of the end portion of said first wire projecting outwardly from its point of engagement by said driver extension, said driver operating to force said projecting wire portion against said anvil concavity, whereby said projecting wire end portion is bent around the standing portion thereof at the side thereof opposite to the direction it was caused by said driver to approach said standing portion, during the final portion of the movement of said driver, both the bend of the first wire about the second wire, and the bend of its end portion about its standing portion, thereby being accomplished by a single motion of said driver member in one direction, after which said driver member returns to its starting position.
