Introduction

Walter E. Lott is a notable inventor based in Washington, IL (US), recognized for his contributions to the field of earth-moving vehicles. He holds 2 patents that showcase his innovative designs and engineering expertise.

Latest Patents

Lott's latest patents include a four-wheel drive scraper with main propulsion at the rear axle. This off-highway earth-moving vehicle features a tractor section and a scraper section interconnected by a draft frame, providing rolling rigidity. Each section is equipped with a pair of ground-engaging wheels. A floating axle assembly on the tractor section allows for independent movement of the tractor wheels, adapting to ground contours. The scraper section is powered by a prime mover with a torque converter connected to the rear axle, while also driving an AC synchronous generator linked to an induction motor in the tractor section. The design ensures that the weight applied to the scraper wheels is approximately twice that applied to the tractor wheels, optimizing performance.

Another significant patent is the two-engine four-wheel drive scraper, which similarly includes a tractor section and scraper section. In this design, the scraper section is driven by a first engine with a torque converter coupled to the scraper wheels, while the tractor section is powered by a second engine. The proportions of weight and power distribution are designed to maintain the same efficiency as his previous patent, ensuring that the power supplied to the scraper wheels is approximately twice that supplied to the tractor wheels.
