One of her latest inventions is the Roll-tight tarp system. This tarp assembly is designed for covering the open top of a truck trailer. It features a tarp with a longitudinal edge fixed to one side of the trailer. A roll bar secured to the free edge of the tarp can be rotated with a crank rod to roll the tarp to an open position and unroll it to a closed position. Additionally, a hold bar fixed to the free edge of the tarp engages hooks secured to the side of the trailer, ensuring the tarp remains in a closed position. The hooks guide the straps and retain the hold bar in alignment for mutual engagement with the hooks.
Another significant invention is the vacuum grain moving apparatus. This apparatus is connected to a three-point hitch of a tractor and operates using the power take-off drive of the tractor. It includes a grain holding tank connected to a grain collection hose, which is used to carry grain and air to the tank. An air moving unit mounted on the tank features a rotatable power-driven impeller that draws air from the center of the chamber, creating a vacuum pressure within the tank. The impeller has first and second generally radial blades that pump the air from the tank chamber. An auger conveyor associated with the lower end of the tank moves the grain into a transport vehicle, ensuring efficient grain handling.
