Suiter Swantz IP takes a look back at past inventions and inventors with our Patent Of The Day.
On this day in 1966, Henry F. Keates was granted U.S. Patent No. 3,243,214 for a TWINE TYING MECHANISM.
This invention comprises a new and improved twine tying mechanism for a baler, more particularly, a twine knotter that produces stronger knots by wetting the twine as each knot is tied.
While prior art twine-tying mechanism produce defective knots less than one percent of the time, the few “misses” that still occur are a nuisance because they allow bales to break up and scatter about the field. Needless to say, scattered bales reduce the efficiency of the baling operation, since they must be cleaned up by hand.
Defective knots sometimes result from slippage of the twine, which occurs when the baled material expands and pulls the knot apart. It is an object of this invention, therefore, to provide a twine-tying mechanism for tying a knot that is less apt to be pulled apart when subjected to large tension forces. This object is achieved by means of a pump that wets each knot during the final stages of its formation.
