722 THE COLLIERY GUARDIAN. April 4, 1913. is so placed as to receive the material flowing down through said tubular member, and which is adapted to discharge said material in different directions from said tubular vertical member into the hold of the vessel so as to substantially trim the load. The invention also includes means whereby said hopper and chute mechanism may be raised and lowered as a unit to better adapt the apparatus for economically loading vessels of various sizes—i e., those which set high and low in the water. The apparatus includes a car dumping machine, by means of which a loaded railway car may be raised bodily to any desired elevation, and tipped over so as to dump its contents into a hopper which is vertically adjustable on the frame or tower of the car dumping machine. The chute mechanism referred to carried by each tower will preferably consist of a trough which is inclined from its rear end downward at such inclination that the material will slide down it. This trough will be movable endwise in suitable guideways, and by suitable mechanism, such, for example, as properly reeved cables, winding drums A H'M ■S! —and motors for turning them. The path of this movable trough will be beneath the discharge spout of the associated hopper, so that, whatever may be the position of the trough, the material in the hopper may be discharged into it. At the outer end of this trough is a housing adapted to serve to guide the vertical movements of a vertical member. Within this vertical member is a vertical U-shaped tube, which is open at its rear side so that material sliding down the trough may fall into it. There are, however, sliding plates below said trough arranged so that they must always overlap and close the rear end of the U-shaped tube below said trough. The trimmer mechanism is secured to the lower end of the vertical member. It will preferably include a sleeve which is capable of rotating about a vertical axis, and there will be mechanism for so turning it. A cage for the operator will be fixed to this sleeve. A frame will be pivoted on a horizontal pivot to the lower end of this sleeve, and this frame will carry a belt conveyor or some equivalent mechanism arranged to receive the material as it flows from the lower end of said vertical U-shaped tube and discharge it over the outer end of said pivoted frame. Mechanism will be provided for turning said frame upon its axis so as to raise or lower its free end. It is proposed also to provide means by which to regulate the rapidity of the discharge of the material from the conveyor into the hold of the vessel. The car dumping machine may be provided with two chute mechanisms generically like the chute mechanism previously described, but preferably they should differ in the following particulars. The downwardly and outwardly inclined movable trough should preferably be made of several telescoping sections, so that when drawn inward the rear end would not project into the path of the loaded car which is being raised for the purpose of dumping it. Additionally, the exterior of these telescoping sections should preferably be mounted so as to swing about a vertical axis. Fig. 1 is a front elevation showing somewhat diagrammatically an apparatus embodying this invention; fig. 2 is a plan view thereof upon the same scale; fig. 3 is a front elevation on a large scale of the car dumping machine which forms a part of the apparatus; fig. 5 is an end view of one of the movable towers which forms a part of the apparatus; fig. 7 is a sectional plan view of the vertical member of the chute apparatus; fig. 8 is a side elevation thereof partly broken away.

Stallmen and the National Insurance Act.—The miners of the South Staffordshire and North Worcestershire area recently took the opinion of the Insurance Commissioners on the following point which has arisen with some of their employers. In some districts the men work on the tonnage or stall system, under which groups of men are employed under the direction of one miner, who receives the pay for all and distributes it. The miner in question is recognised by the employers as the man in charge of the stall, and in several instances he has been treated as a sub-contractor, and has been required to pay the contributions for the men under his control. One of the men employed under the stallage conditions was recently taken ill, and it proved that he was not entitled to benefit, as no contribution had been paid by his employers. The Old Hill and District Miners’ Association submitted the facts to the Insurance Com- missioners, and an inspector visited the district. The employers also submitted their side of the case. The Insurance Commissioners hold that a man who is placed in charge of a stall under the conditions described cannot in any sense be regarded as a sub-contractor. A person who becomes a charter-master and is employing men for his own 'personal profit can only be looked upon as a sub- contractor. In the case in point the man in charge of the stall receives no higher wage than any of the other workmen. The Commissioners have directed that the whole of the payments for the last nine months shall be met by the colliery company, and not by the stallman. A somewhat similar decision has been obtained in the case of men employed in clay mines under the guidance of a “ doggy.” The latter has paid the men who work with him, and the employers have sought to make him a sub- contractor. The Commissioners, however, have held that a “doggy” can only be a sub-contractor when he has the supreme power to work the pit. The “doggy,” in other words, must be engaged upon the same terms as the charter-master, and must be in receipt of a percentage of the profits of, the pit before he can be classed as a sub-contractor.
