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.
A holding device for a chain, particularly a chain associated with a coal cutter and having chain members located in two mutually transverse planes, the holding device comprising a one-piece chain block mountable on a support and having two portions which are of one piece with and immovable relative to each other, said chain block having a U-shaped recess formed in said relatively immovable two portions and dimensioned for receiving one end section of one of the chain members which is located in one of the planes without displacement of said two portions relative to one another and so that said end section is embraced by said two portions in said one plane at both sides of said end section and is also embraced by said two portions in said other plane at both other sides of said end section, said chain block further having a slot which is bounded by said relatively immovable two portions and located in the other of said planes and which is dimensioned for receiving the other chain member which is located in the other of said planes also without displacement of said two portions relative to one another.
The holding device as defined in claim 11, wherein said U-shaped recess formed in said first mentioned portions is open in a direction towards said U-shaped recess formed in said other portions and vice versa, so that the other end section of the one chain member is received in said latter-mentioned U-shaped recess.
