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.
Abstract: A locking element for connecting two chain links is comprised of two elongated locking members each having a recess and two end portions spaced from one another. The locking members can engage one another in which position the one end portion of the one locking member engages the other end portion of the other locking member and vice versa, in one and another planes. The recesses of the locking members together form an inner circumferentially closed recess in which the chain links can move. The locking members can be disengaged from one another, in which position the chain links can be withdrawn from the inner recess. The above planes are offset relative to one another so that during movement of the locking members between the above two positions the chain links received in the respective recesses are moved in planes parallel to the above planes of the engagement of the end portions of the locking members.
