Abstract: The present invention discloses a chain where, upon the stressing of the chain, the links automatically arrange themselves with respect to one another in terms of their position in the chain, preventing any undesired link. A link can be developed in the form, in top view, of a drop or in the form of a keyhole. The described chain is not only suitable for application in lashing loads, but also for use with the manipulation of all accessory chain parts, in which the placement of a link is required, for example shortening hooks, shortening straps or the like.

Abstract: Rope chain link elements and a manufacturing process to make such link elements, each link element exhibiting a unique visual property, such as coloration, surface texture, reflectivity, design feature or characteristic, shape, or other visually attractive appearance. Methods of construction include surface pre-texturing, stamping, simultaneous surface texturing and stamping, and wire bending. Such unique visual property traits for the succession of link elements results in a more attractive, fanciful, more delicate and interesting fashion item. Each of the interconnected link elements may have the same or different visual properties, and may have multiple portions of varying color, texture, or other visual properties. In other aspects of the invention, each link element may have differently shaped portions, such as adjoining and connecting geometric or heart shaped segments. Additionally, the interior and/or exterior edges of the link element may exhibit different shapes, colors, patterns, or textures.

Each link has a cross section with the largest transverse distance across the cross section defining a first dimension. Each link has a interior space and a gap along the periphery of the length. The widest dimension of the interior space in a direction consistent with the direction of the gap has a dimension which is less than three times the first dimension. Thus, ratios of approximately 2:1 can be achieved.

Abstract: A chain link of hollow construction and substantially uniform thickness, for intertwining with other chain links to form a jewelry chain, has a non-annular cross-section throughout the link with the cross-section being symmetric along a centerline plane through said cross-section. The cross-sectional shape of the link preferably has on each side of the centerline plane, at least two sides that meet at a point of inflection. On each side of the centerline plane, at least one side preferably converges toward said centerline plane. A reduction in manufacturing costs and precious metal used to form the links and therefore the chain is realized by using a non-annular cross-section having such constructional qualities.

Abstract: A double helix jewelry chain is constructed from a series of interconnected chain links. Each link is formed with an open mouth defined between a pair of end faces. The end faces are aligned with one another in various predetermined geometrical and dimensional relationships in order to maintain a minimum projected gap or clearance opening equal to or less than the major dimension of an elongated cross section of each link.

Abstract: An elongated chain link comprising a pair of opposing U-shaped end portions connected by a pair of parallel leg portions. The leg portions are connected to each other by a pair of crosswise tie-bars situated toward the end portions approximately equally offset from the cross-axial centerline of the link. Additional crosswise tie-bars may be added to prevent the legs of the link from collapsing together when a large side-load is applied to the link. The leg portions are substantially square in cross section, while the end portions comprise an inner portion having an arcuate inner surface and an outer portion being substantially rectangular in cross-section. The chain link is preferably made of a high-strength cast alloy steel and is especially well-suited for use in dragline drag and hoist chains.

Abstract: A jewelry rope chain formed of a number of links of wire of a cross sectional configuration. The links are intertwined to form an outer appearance of a double helix. A predetermined number of the links is required to form a full helix cycle. At least some of the overall geometric shapes of the links within a full helix cycle are different from the overall geometric shapes of the other links within the same helix cycle. The chain can be formed either by initially selecting the links of different geometric shapes and intertwining them in accordance with a desired sequence. Alternately, initially the chain can be formed of uniform links and thereafter the entire chain rolled or reshaped so as to reconfigure the shape of at least some of the links with respect to other of the links within a full helix cycle.

Abstract: The invention is a unitary component that may be substituted intermittently for portions of a jewelry rope chain. The unitary component has connecting means that promotes the integration of the component with the conventional rope chain by receiving onto the component the individual links of the rope chain in their ordinary sequence and position as those links are sequentially and positionally comprised on a conventional rope chain. The use of the component with conventional rope chain segments results in savings of precious metal and labor costs while retaining many of the flexibility and aesthetic advantages of the conventional rope chain. The preferred embodiment of the rope chain is spiral in shape but may take on various other configurations.

Abstract: Chains having links in the shape of a figure eight can be made by the method and apparatus of the present invention. The last link of the chain is first held in a secure position. Oval shaped loops are cut from an oval shaped helix in such a manner that the ends of the loops are spaced apart. The ends of the loops are then passed through the eyes of the held last link of the chain. The ends of the loop are then closed and the loop is then grasped at opposite ends of the oval and twisted to form the figure eight shape. The present invention has a collet 30 for holding the last link of the chain, a collet 40 for grasping the loops created from the oval shaped helix. The collet 40 is movable for insertion of the arms of the loop into the eyes of the last link. A clamp 50 joins the ends of the loop and the clamp 50 and collet 40 then perform a twisting motion which results in the loop being formed into a figure eight shape.

Abstract: An improved passenger car tire chain employing heat treated medium carbon steel is disclosed. The improved tire chain is approximately twice as durable as that presently furnished to meet NACM-5179(TC) for Type PL chains when AISI 1026 or 1029 carbon steel is employed at least for links of a cross chain meeting the road surface. The cross chain links are closed by welding prepared abutting link ends which have been previously beveled. After being welded closed, the cross chain links are case hardened, quenched, tempered and air cooled. The improved tire chain is then assembled in a conventional manner to include a pair of side members, fastening means to secure a end of each side member to the other end, and a plurality of cross chains extending between the sidewall members at preselected intervals.

Abstract: The disclosure sets forth a different annular link as the building element; instead of using a split annular link of a 3:1 ratio of link inner diameter to major wire diameter, the link has substantially thinner annulus for forming the rope chain, an annulus that requires an over 5:1 ratio of inner annulus diameter to major wire diameter. The presently preferred ratio is between 5.2 and 5.7:1. It is possible to use even thinner annuluses, i.e. having greater ratios, e.g., 7.2-7.7:1 with even greater weight savings (approximately 35%), or other even greater odd-numbered ratios of inner annulus diameter to major wire diameter (e.g. 9.4-9.9:1). Thus, while there is no theoretical limit, there is probably a maximum practical upper limit to the ratio of inner annulus diameter to major wire diamater.
