Abstract: A tennis ball collection device includes a rotating drum that rotates at a higher speed than the rotation of the wheels that carry the device. Additionally, the drum rail that operates in connection with the rotating drum to lift a ball off of a ground is allowed to move in the horizontal direction. This back and forth movement is facilitated by a spring that otherwise biases the drum rail forward to a rest position.

Abstract: A cart that collects tennis balls on the ground when manually pushed by a user and stores the tennis balls once collected. The cart includes a housing, a gathering assembly, a conveyor assembly, and a receptacle. The housing is manually pushed by the user. The gathering assembly is operatively connected to the housing, and gathers the tennis balls on the ground. The conveyor assembly is operatively connected within the housing. The receptacle is disposed against the housing, and stores the tennis balls elevated thereto by the conveyor assembly that have been gathered by the gathering assembly.

Abstract: A ball retrieval device that picks up tennis balls from the ground and vertically elevates them into a cart. The ball retrieval device includes an L-shaped frame including a first section and a second section. A feeder system is located on the horizontal section of the L-shaped frame and a paddle wheel system is connected to the feeder system. A lift system is located on the vertical section of the L-shaped frame.

Abstract: A container transportation system that includes a dolly system that can be mounted underneath the container and then used, optionally in cooperation with a boom or lift, to navigate a container to a desired location. The dolly includes a motor mounted in a swivel bracket that facilitates movement of the dolly for storage. The dolly includes a locking mechanism to clamp in on a load. The dolly can be navigated through the use of a wireless remote control unit that is either held by an operator or by a device that is integrated into the electronics of a road tractor and/or dolly system. The system may include a mounting system for mounting the dolly to a road tractor and a boom for lifting the dolly from a deployed state to a loaded state.

Abstract: An apparatus includes a trailer support, and a lift mechanism attached to the trailer support. The apparatus also includes a first drive unit attached to the trailer support, and a second drive unit attached to the trailer support. The first drive unit steers the trailer support. The second drive unit moves the jack.

Abstract: A pick-up device for a load includes a shaft having a central axis, rollers disposed on the shaft, an engagement device pivotably mounted to the shaft for engaging the load, the engagement device being mounted to the shaft at a distance from the central axis, a pulling member for pulling the load, the pulling member being disposed on the shaft at a distance from the central axis so that a pulling force applied to the pulling member applies a torque to the shaft so as to pivot the engagement device in a direction of lifting of the load; and a cam disposed on the shaft and the engagement device for preventing further pivot of the engagement device relative to the shaft when the load has been lifted a desired height.

Abstract: A machine to collect iron or steel shot or ferrous grit from factory plant floors for reuse in blast machines or other industrial processes. Round doughnut like magnets mounted on a through shaft are stacked together with like North and South poles adjacent one to another in or such as N-SS-NN-SS-NN-SS-NN-SS-NN-SS-NN-S. A drive system includes a floor engaging wheel and a lug pulley and belt drive connected to a gear drive connected to one end of the through shaft that mounts the end to end round magnets extending transversely substantially the width of the machine. A multi-pocketed flexible conveyor belt is passed around the shaft and end to end magnet assembly to extend therefrom up and around idler drum located upward and toward the rear, that being non-magnetic permits iron or steel shot and/or ferrous material grit to dump from the multipocketed belt down to the separating screen.
