One of Grayson's notable inventions is the "Power takeoff adapter for drive shaft." This device is designed to extend a power shaft, such as the crankshaft of an engine. The power takeoff adapter features a male pin that fits into a complementary female receptacle in the crankshaft. During operation, the torque applied initially tightens the coupling between the adapter and the crankshaft, enhancing efficiency.

Another significant patent is the "Rocker box cover assembly for internal combustion engine." This improved assembly is designed for overhead valve, horizontal crankshaft engines. The cover assembly is a pre-assembled unit that attaches to the cylinder head. It includes an inner cover section that defines a rocker arm chamber and an outer cover section. The space between these sections creates an oil separating chamber. The inner cover section has an opening that allows communication between the chambers, and a check valve is mounted in this opening. Additionally, a gas outlet is located in the upper portion of the oil separating chamber, while a drain opening at the lower end allows separated oil to return to the crankcase.
