Patent number: 9028194Abstract: An apparatus such as a shuttle bin includes an upper frame, a lower frame hingeably connected to the upper frame, a storage body operatively connected to the upper frame for storing material and a roller assembly operatively connected to the upper frame. The roller assembly is adapted to draw the storage body taut to unload the material stored in the storage body as the upper frame hinges away from the lower frame. The storage body may be formed of a pliable material such as a mesh or canvas.Type: GrantFiled: September 7, 2012Date of Patent: May 12, 2015Inventor: Stephen L. Wahls

Patent number: 6035942Abstract: A full truss tool bar is disclosed comprising an elongated main tool bar section having right and left tool bar wing sections positioned at the right and left ends of the main tool bar section. An elongated main truss member is positioned above the main tool bar section and is secured thereto. Right and left truss members are positioned above the right and left tool bar wing sections and are secured thereto. The main truss member is pivotally connected to the right and left truss members, about horizontal axes. In a modified version of the device, auxiliary tool bar sections are positioned outwardly of the right and left tool bar wing sections and have truss sections positioned thereabove and secured thereto. The trusses on the auxiliary tool bar sections are pivotally connected, about vertical axes, to the outer ends of the right and left tool bar wing sections.Type: GrantFiled: September 2, 1998Date of Patent: March 14, 2000Assignee: Hawkins Mfg., Inc.Inventors: Casey P. Smith, Stephen L. Wahls

Patent number: 5542190Abstract: The present invention is bifold field marker. The marker utilizes a marking disc mounted on the distal end of an arm. This arm is coupled to a mounting bracket which, in turn, is connected to an implement's tool bar. The arm is articulated at a central knuckle to allow the marker to fold. A hydraulic cylinder is positioned between the mounting bracket and the arm to push or pull the arm about a main pin or hinge. When the arm is in an extended horizontal position, the main pin or hinge on the mounting bracket is oriented at an angle both from the direction of travel and from the ground. This allows the hydraulic cylinder to pivot the arm about the main pin's axis and fold both sections of the arm simultaneously to a point where the marker is positioned in a compact orientation along the side of the implement.Type: GrantFiled: January 30, 1995Date of Patent: August 6, 1996Assignee: Orthman Manufacturing, Inc.Inventor: Stephen L. Wahls

A hydraulic cylinder is positioned between the mounting bracket and the arm to push or pull the arm about a main pin or hinge. The main pin or hinge on the mounting bracket is oriented at a 45 degree angle in both the horizontal and vertical planes. This allows the hydraulic cylinder to pivot the arm about the 45 degree axis and fold the arm simultaneously until the marker is positioned in a compact orientation along the side of the implement.Type: GrantFiled: November 9, 1993Date of Patent: April 25, 1995Assignee: Orthman Manufacturing, Inc.Inventor: Stephen L.

Patent number: 4480430Abstract: The asparagus picking machine of the present invention comprises a frame assembly which is adapted to be carried by a vehicle adjacent to the ground. A continuous picker belt assembly is mounted on the frame assembly and is trained around a forward sprocket, a rearward sprocket and a chain guide means which is located between and below the two sprockets. The picker belt assembly comprises a plurality of elongated spaced apart parallel picker bars extending parallel to the rotational forward and rearward axes of the sprockets. The belt assembly includes chains which interconnect the spaced apart picker bars. The chains are trained around the forward and rearward sprockets and are guided through the guide means so as to travel in a downward and rearward inclined path from the forward sprocket to the guide means and then through an S-shaped pattern as the chain passes through the guide means.Type: GrantFiled: December 8, 1982Date of Patent: November 6, 1984Inventor: Stephen L.
