Abstract: A device for heaving in chain (2,3) vertically by means of a locking device for the chain comprises one or more pawls (14,14') which engage the chain (2,3) in a combined hydraulic lifting (8) and gripping device (12) with an equivalent pawl system and an approximately 180.degree. guide device (1) for the chain. The guide device (1) and the lifting (8) and gripping device (12) are integrated in one unit in that the semicircular guide device (1) is hinged in the area which is furthest away from the incoming part of the chain, and that the gripping device consists of one or more pawls (12) which can hold the chain while it lies in its track (4,5) in the guide device (1). A hydraulic lifting cylinder (8) is hinged to the guide device (1) close to the incoming part of the chain.

Abstract: A shed forming device for a shuttle loom includes a carrier (6) for at least one shuttle (5, 5') and a stationary frame (1) accommodating a reed of wires or dents (7) disposed in a plane extending parallel to the direction of movement of the shuttle carrier (6). A freely rotatable toothed wheel (4) is mounted on the shuttle carrier (6) in front of the corresponding shuttle, at an angle to the reed plane and in engagement with the reed wires or dents (7) to form a shuttle shed. The toothed wheel (4) is mounted on the opposite side of the reed plane with respect to the shuttle carrier to better accommodate the shuttle carrier.
