US Patent:

47346833, Mar 29, 1988

Filed:

Feb 10, 1987

Appl. No.:

7/015555

Inventors:

Mark E. Howell - Parma ID
James M. Howell - Wilder ID

International Classification:

G08B 2100

US Classification:

340684

Abstract:

A vehicle guidance system which monitors the path of a towed farm implement with respect to a track provided by a previously cut furrow and provides visual cues to the towing tractor operator to maintain the path of the towed implement parallel to the track of the previously cut furrow at a constant, predetermined distance regardless of the path of the tractor towing the implement. The guidance system includes an elongated metal sled runner which is mounted on a doubly articulated carriage device. The sled runner rides in a previously cut furrow and closes an appropriate microswitch if the towed implement veers from the desired path.

Abstract:

Apparatus for adjusting the angular position of the pulleys in a compound bow is mounted on each of the pulleys, not between the pulleys. The apparatus consists of either rotatable or slidable elements which are mounted on the pulleys. The tension cables contact these elements. The elements are designed such that movement of the elements moves the tension cables and causes changes in tension in the tension cables. This causes rotation of the pulleys, thus changing the angular position of the pulleys. The rotatable elements consist of either eccentrically mounted or shaped cams. The tension cables extend around the cams and are anchored to the pulleys. The rotation of the cams causes changes in tension in the tension cables, thus changing the angular position of the pulleys. The slidable elements consist of either a set screw or a sliding plate. In the case of a set screw, one end of the set screw contacts the tension cable and the tension cable is anchored to the pulley.
