62 THE COLLIERY GUARDIAN. July 10, 1914. It only needs a trial to prove above which we are prepared to guarantee Present users acknowledge tremendous saving. to one / potn^- / for Collieries. We have systems at work in seams of 16 in. yielding an output of 5 to 7 tons per man per shift. We are certain a saving can be made in any mine that will pay for the outlay in three months, no matter what the total cost of the plant may be. The greater the length of face the greater the output, and we can deal with 400 tons of coal per shift on one Conveyor, and any length of face dealt with. The Mining Appliances System of Mining Coal has been adopted at many Collieries and considerable savings have been made in every case. Blue prints supplied showing our Systems and full details of cost, etc., free. “ EICKHOFF ” CONVEYOR Telephone— 2401 Central. We are Sole Proprietors of the “Eickhoff” Patents.
