ABSTRACT:
The invention provides a tool for assisting the flow of ready mixed concrete down a sloping chute and also for stopping such flow. The tool includes a retaining plate shaped to fit inside the chute when placed in the chute across the direction of flow. A shaft is connected at one end to the plate and at the other end to an end piece connected generally at right angles to the shaft. The tool may be used by gripping the end piece and placing the end plate in the chute to pull concrete down the dispensing chute. Also, by placing the end piece around a fixture on the chute and the end plate in the chute, flow of concrete down the chute will be limited.
