Latest Patents

Holmes' latest patents include a hydrostatic transmission overspeed prevention circuit. This hydraulic circuit is designed to prevent overspeeding of the prime mover that powers a hydrostatic transmission. The system includes a hydraulic motor fluidly coupled to a hydraulic pump, which is driven by the prime mover. The hydraulic pump features a swash plate tilted by a servomechanism that receives hydraulic fluid from a pump powered by the prime mover. A valve is operated to shut off the hydraulic fluid to the servomechanism if the pressure in the conduits exceeds a pre-set maximum value. This innovative circuit prevents overspeed conditions from occurring, making it superior to devices that react after an overspeed condition is detected.

Another of his recent inventions is a latching mechanism for a spreader. This mechanism is designed to attach a spreader to corner castings of a container. It features an elongated shank with locking lugs at one end and a locator member surrounding the shank. The mounting means allows for universal movement of the shank about a fixed point on the frame, accommodating different types of standard castings with varying transverse spacings.
