The Mechanical Handling and Storing of Material

COAL TIPS OP HOISTS 525 of Lens;1 also by the Bruay Mining Co., Calais,2 in connection with their loading basin at the north of Bethune. The capacity is rather less than in th© case previously described, as it will only handle seventy wagons of 10 tons each per day. The Noeux Co.’s Tip.—This device, which is again similar to those just described, is illustrated in Fig. 732. It has been used at the dock of the Noeux Co., in connection with the canal of La Bassé å Aire. There is a fixed hopper or frame formed of two ribbed cast-iron cheeks solidly bolted to the wall of the wharf, on which is fixed a crane for handling a movable shoot. This movable shoot is connected to the fixed hopper by a spout which can be turned in any position around a vertical axis, and distributes the coal over the area thus commanded. The trucks are of special construction, and their bodies consist of three boxes of a capacity of 3| tons each, which are tipped separately. Fig. 732. The Noeux Co.’s Tip. On the side next the hopper the boxes are provided with doors hinged horizontally at the top, and engaging in clips which are fastened a little back upon the ends of the car. At the bottom of this door two pins are fastened which work laterally, and are caught, when the box rests on the truck, by two dogs attached to the sill.3 With this arrangement, when the box is raised from the back, the pins on the door are gradually set free from their dogs, and at a certain point the door becomes unfastened and opens for the passage of the coal. On the return, when the box is empty, it drops back on the under frame, the pins catch under their dogs, and the door is fastened.
