Latest Patents
One of Johnson's latest patents is for a trailer designed specifically for carrying combine cutter heads, whether for corn or small grains. This innovative trailer avoids interference with the combine during loading and maintains proper load balance after the head is loaded. It achieves this by utilizing a movable trailer-wheel axle that shifts from a normal road position to a rear position, allowing the combine to drive up to the trailer for easy detachment and loading of the head.
Another significant patent is for an apparatus that controls the movement of strands from a rotating strand supply. This apparatus allows for the control of relative strand movement without significantly affecting strand tension on a braiding machine. It features two sets of carriers for strand supply bobbins that rotate in opposite directions. The design includes cam actuated swing arms that guide the rear strands through an arc segment for interweaving with front strands, ultimately leading to a circular ring for tight braiding around a core or mandrel.
