Latest Patents
One of his latest patents is an innovative exhaust system for vehicles. This system includes a valve with a movable valving element that directs exhaust from the vehicle engine to a muffler based on the position of the vehicle body. When the body is raised, exhaust is directed entirely to the muffler. Conversely, when the body is lowered, the exhaust is partially directed through the muffler and partially through a member of the body portion. An over-center spring biases the valving element, while a plunger moves it to its second position in response to the lowering of the vehicle body.
Another significant patent is the wagon door control system, which allows operators to control the operation of dump doors on a wagon. This apparatus enables the operator to set a control lever in either a closed or open position, facilitating the desired movement of the doors. The system includes a cam device that responds to the movement of the doors, ensuring the control lever returns to a 'Hold' position upon completion of the desired movement. This invention can provide either a single full movement of the doors or a sequential movement, depending on the operator's preference.
