Improvements in Means for Actuating Shaking Chute Conveyors. B. H. Lindhorst, Knights Deep Limited, Germiston, Transvaal, South Africa.—Relates to means for actuating shaking chute conveyors, of the kind used in the underground workings of mines, and which ordinarily comprise sectional, included troughs, suspended by means of chains or other flexible media, down which troughs the broken or fragmentary ore, mineral, etc., falls to the desired point of delivery. A lever (or levers) is (or are) pivotally attached to one extremity to the conveyor trough, being also connected or attached to a chain or other flexible connection, suitably fixed at a point above or below the con- veyor trough. Fig. 1 is a side elevation; and fig. 2 an end elevation of portions of fig. 1. The .actuating lever 1 is posi- tioned at one side of the sectional trough conveyor 2. 3, 4, 5, 6 are the chains by which the conveyor 2 is suspended from the hanging wall or roof 7; 8 being the hooks at the lower ends of the chains 3, 4, 5, 6, which hooks engage with oval holes or elongated slots 9 in the sides of the various over- lapping sections. 10 represents suitable fixings, from which are suspended the chains 3, 4, 5, 6. 11 represents a bale or bridle, shown constructed of two parts bolted together. The ends of the bale or bridle 11 are free to work in holes provided in the sides of one section of the trough; 12 representing a plate for strengthening the trough at that point. On one end of the bale or bridle 11 the lever 1 is pinned or other- wise fixed. 13 is a preferably adjustable weight, fixed on the lever 1. This weight serves for keeping the operating lever 1 more or less horizontal. The bale or bridle is pro- vided with a vertical extension 11*, in which is provided a number of holes 14 for the purpose of adjustably attaching thereto one end of a chain 15, the latter being provided with a hook 16 for engaging in any one of said holes. The other end of the chain 15 is fixed by suitable means 17 to the hanging wall or roof at a point .above, as shown, or below the trough 2, at some distance from the bale or bridle 11 in the dierction of the upper end of the trough 2. The weight 13 counteracts the effect of the chain 15 on the lever 1. In some cases the lever 1 may not require to be provided with the counterbalance weight 13, but may have to be counter- balanced on the opposite side of its pivot. This may be effected by providing an extension 18 on the lever 1 and mounting a counterweight 19 so that it can be adjusted along the said extension 18. In operation, the outer end of the lever 1 is pulled downward, causing the upper end of the bale or bridle to pull against the chain 15, with the result that the conveyor trough 2 is moved bodily in the direction of its upper end. The lever is then released, and allows the trough to swing forward, the momentum thus acquired causing the chute to swing beyond its normal position and the lever 1 to rotate about its pivot until they are arrested by the extension on the bale coming into line with the chain 15. The for- ward motion of the chute 2 is, at this moment, arrested with a jerk, thus causing the material to continue its movement down the chute. (Four claims.)

Hull Coal Exports.—The official return of the exports of coal from Hull to foreign countries for the week ended July 25 is as follows: Amsterdam, 456 tons; Alexandria, 1,979; Dunkirk, 3,973; Genoa, 8,045; Guernsey, 154; Hamas, 596; Harlingen, 1,248; Jersey, 366; Naples, 510; Rouen, 6,684; .Rotterdam, 253; Treport, 1,256; total, 25,520 tons. Corresponding period July 1915, total 45,085 tons. These figures do not include bunker coal, shipments for the British Admiralty, nor the Allies’ Governments. Supply of Coal to France.—The secretaries of the various local committees dealing with the supply of coal to France attended at the Hotel Victoria, Northumberland-avenue, London, on Monday, M. Weiss, French Minister of Mines, and members of the French Committee in London being also present, to consider cases of hardship where steamers which had been chartered for July loading were likely to be detained. In the ordinary course, only July licences would be available for the supply of coal to these steamers. After full consider- ation, M. Weiss agreed that the July licences should be made available for the loading of steamers which start loading before to-morrow (Saturday) midnight. These steamers, under this arrangement, will be allowed to complete and clear, although the coal loading may not be complete till subsequently. The members of the committee present were : Mr. M. R. Hawkins (Chamber of Commerce, Cardiff), Mr. H. J. Marshall (Chamber of Commerce, Swansea), Mr. R. Moorby (Hull), Mr. R. M. Stewart (secretary of the Central Executive Committee of Great Britain), and the secretary of the Newcastle Chamber of Commerce. Lieut. Thoumyre, of the French Committee in Paris, discussed with the local secretaries various points of detail in the scheme.
