Abstract: A chain lock for high-strength steel chains has two lock parts that are the same and can be joined together in a rotation-symmetry arrangement with one another, in the longitudinal direction. Each lock part has a longitudinal stay having arc segments that follow it at both ends. There are two coupling elements that are configured complementary to one another and are assigned to the two arc segments of each lock part. One of the elements is configured as a locking stay that follows the longitudinal extension of the lock part, and the other element is configured as a stay accommodation. The locking stay of the one lock part engages in the stay accommodation of the other lock part and rests against the complementary coupling surface of the stay accommodation with its coupling surface formed by the face end in the joining direction. The coupling surfaces comprise a coupling surface segment having a defined width, which has no curvature or only an insignificant curvature pointing in the joining direction.

Abstract: The invention relates to a plough chain strand 50 with horizontal chain links and vertical chain links including normal chain links 30, 40, the chain link legs of which are connected by chain link arcs and engage one another alternately in an intractable manner. In the chain strand 50 in front of and behind the chain connector link 10 is arranged in the same installation position as this at least one special chain link 20, the link legs of which comprise the same outer contour, especially the same width and the same thickness, as the outer legs of the connector link parts of the chain connector link 10. Due to the special chain links 20 preceding and trailing the chain connector link and having the same or a marginally larger contour as this, the wear of the chain connector link 10 of the chain strand 50 according to the invention is reduced or avoided if compared to known plough chains.

The connector is provided with integral fasteners for removable attachment of a length of flail chain to a powered rotary shaft, The connector may be removably engaged with the flail chain by moving a rink in the flail chain and one integral fastener to a first relative position and thereafter moving the link and fastener into a second relative position. The connector may be disengaged from the flail chain by relative movement of the link and fastener from the second position to the first position, and finally to the disengaged position. The connector may be removably engaged to the shaft by a second fastener through relative movements to a first and second relative positions.

Abstract: A self-locking link includes two identical link elements which are adapted for connection to two chain links and for mutual engagement with each other. Each link element is generally L-shaped and includes a head portion and a body having an aperture therein. Each body aperture includes an enlarged portion as well as a narrower, elongated portion aligned with a straight line extending between the two chain links to be coupled. The enlarged portion of each aperture is adapted to receive the head portion of the other link element and includes a V-shaped notch therein extending along the aforementioned straight line between the two coupled chain links. Application of a work force along the thus connected link elements of the generally rectangular shaped self-locking link results in the displacement of the head portion of each link element into the elongated portion of the aperture of the other link element.

Abstract: A connecting chain link with two loops for accommodating chain links of attached chain lengths comprises two main link parts identical in shape and dimensions and assembled along a first contact surface and a second contact surface which is complementary to the first one, and a limiting surface in the central portion of the link. The contact surfaces extend between an origin at the outer periphery of the link and close to a transverse axis thereof, and a termination at the inner periphery of one of the loops. The contact surfaces consist of a plurality of differently oriented surface sections and are so shaped as to form a plurality of intermeshing lug and recess means which effectively oppose tension stresses in the longitudinal direction and all stresses in the transverse directions, the latter ones particularly efficiently at the locations of said origins.

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.
