US 4,166,353 A · Two-way rake

Abstract

The pull-type rake is designed to remain in a preselected trailing position relative to the towing vehicle while the raking head may be cocked to the right or left without the operator leaving the driver's seat, thereby placing the head in condition to deliver raked material leftwardly or rightwardly depending upon the selected angular position for the head. The main chassis of the implement is constructed in the form of a parallel, four-bar linkage that may be skewed by the operator into leftwardly or rightwardly oblique positions relative to the path of travel of the implement, thereby cocking the rake head accordingly, and the head itself includes a frame and a reel carried thereby, both of which are constructed in the nature of parallel, four-bar linkages so that they, too, can be skewed by the operator. In a fully skewed position, crop-engaging tines of the reel move leftwardly or rightwardly at substantially right angles to the path of travel of the implement so as to maximize the efficiency of the side-delivery action of the rake.

Dependent claims

A pull-type farm implement comprising:

a chassis having a towing member extending forwardly therefrom in a predetermined angular attitude with respect to the normal path of travel of the implement;
ground-engaging means supporting said chassis for movement along said path of travel;
a header carried by said chassis and operable to deliver ground-engaging crop material from a position in line with said path of travel to a laterally displaced position on a selected one side of said path of travel,
said chassis being provided with means for permitting up-and-down swinging movement of said header relative to said ground-engaging support means;
and
remotely operable control means coupled with said header for selectively reversing the direction of delivery thereof from one side of said path of travel to the other without disturbing said predetermined attitude of said member.

A towable farm implement comprising:

a mobile chassis having a towing member extending forwardly therefrom in a predetermined angular attitude with respect to the normal path of travel of the implement;
means carried by said chassis for delivering ground-engaging crop material from a position in line with said path of travel to a laterally displaced position on a selected one side of said path of travel;
remotely operable control means coupled with said delivery means for selectively switching the direction of delivery of said delivery means from one side of said path of travel to the other without disturbing said predetermined attitude of said member,
said crop delivery means being mounted for swinging movement between a pair of opposite extreme positions corresponding to the opposite directions of crop delivery thereof,
said crop delivery means including a reel having transversely extending bars that move in closed loops of travel during rotation of the reel, said reel being skewable for movement between said opposite extreme positions of the delivery means, said bars shifting longitudinally of one another to redirect said loops of travel during skewing of the reel between said opposite extreme positions,
said reel further including a pair of opposite, rotatable, parallel end supports for said bars, said supports changing their respective planes of rotation during said skewing of the reel but maintaining their parallel relationship to one another,
said bars being mounted on said supports for rotation relative to the latter about axes parallel to the axes of rotation of the supports;
and
means for maintaining said bars in a predetermined rotative relationship to one another throughout movement of the reel between its oppositely skewed positions.
