With a total of 3 patents to his name, Marshall's innovations have streamlined the process of harvesting tomatoes, making it more efficient and effective.
Latest Patents
One of Marshall's latest patents is a method for mechanically harvesting tomatoes. This innovative approach involves moving a mechanical harvester through rows of growing tomato plants, severing the plants below ground, and collecting the severed plants along with loose tomatoes and dirt clods. The design ensures that loose dirt is returned to the ground while the severed plants are separated from the tomatoes and dirt clods. The tomatoes are then shaken free from the plants and conveyed past sorters for quality assessment. The harvester operates at a speed that optimizes the collection process, enhancing overall efficiency.
Another significant patent is for an improved tomato harvester that also severs tomato plants just below the ground. This device picks up the plants and mechanically separates dirt clods and loose tomatoes. The plants undergo vigorous shaking to remove the tomatoes, which are then sorted to eliminate culls. This dual sorting process allows for the efficient recovery of good tomatoes while disposing of unwanted materials.
