ABSTRACT:
A holding device for a chain is proposed, particularly for a chain associated with a coal cutter and having links located in two mutually transverse planes. The holding device has a chain block having two portions formed with a recess and bounding a slot. The recess is dimensioned for receiving an end portion of one of the chain links which is located in one of the planes, and the slot is dimensioned for receiving the other chain link which is located in the other of the planes. The recess may be U-shaped, and the slot extends in the direction of elongation of the chain block. Supporting portions may be provided for supporting one of the chain links which is located in a horizontal plane. Means may be provided for fastening the horizontal chain link to the supporting portions. Two additional such portions may be provided in the same chain block, spaced from the first two portions in the direction of elongation of the chain block. The slots of the two pairs of portions may be formed as a common slot extending in the direction of elongation of the chain block and bounded between the above portions and the supporting portions.
