New Home-Made Wooden Table Allows Faster Cleaning and Inspection of Cones

Thousands of bushels of cones per year are purchased by the Forest Service from private collectors. When the cones are delivered to forest collection points, they are inspected for quantity and quality of seed and are separated from trash and litter. Without proper equipment, inspection and cleaning requires a long time. In the fall of 1964, John Wilson of the Lolo National Forest (Mont.) presented a concept for a cone inspection table that would facilitate inspection and remove most of the litter from the cones. The Missoula Equipment Development Center (MEDC) was requested to design the table. The primary requirements were that the table be as inexpensive as possible and be able to handle cones of various sizes. Commonly available materials were to be used to construct it. The table fig. 1) consists mainly of a vibrating bed, top and base frames, and two platform assemblies. The tabletop is 3 by 8 feet; the bed is constructed of 1- 2-inch slats 1 inch apart. For small cones, the slats are covered with 1/2-inch 1315-gage expanded metal. The sides are 12 inches high. A spout and flap for stopping the flow of cones is at the lower end of the table. The base is
