Abstract: A container filling apparatus comprising a filling chute in the form of an extendable and retractable telescopic tube for extending downwardly into a container. The tube has a closure device for closing the otherwise open lower end of the tube and a cable device to lower the tube as it extends downwardly into the container. A filling device is provided to supply material into the upper end of the tube as it is lowered, as well as device for sensing contact with the floor of the container. There is an operating device to open the closure device in response to a signal from the device for sensing the floor of the container. There is also a probe mounted at the bottom of the tube to sense the proximity of the bottom of a container and/or the level of material in the container. A second probe is mounted at the top of the tube to sense when the tube has been filled to the level of the probe and to temporarily interrupt the feed of material to the tube.
