Abstract: This is a decorative linkwork or mesh of interlinked parts which form a sheet for use as a decorative fabric. The linkwork is formed of small overlapping plates and interconnecting rings. Each plate has four outwardly extending arms which are formed into U-shaped hooks for engaging a respective connecting ring. At least one of the outwardly extending arms is relatively longer than the others and has a predetermined portion of its length folded back flat against the plate, resulting in a spacing between the edge of the plate and the beginning of the U-shaped hook formation of that arm.

Abstract: Link unit of the U-shaped type for use in making continuous chains by interfitting connection with pintles of the base segment of the unit between and to the spaced leg segments of a preceding unit in the chain wherein the leg segments of the units are provided at their ends with slotted bosses for receiving a connecting pintle, the boss slots are adapted to receive plug welds to rigidly weld and attach a connecting pintle to the bosses, and outwardly extending arms are positioned on the leg segments of the link unit forward of and adjacent to the leg segment bosses. In preferred embodiments the plug weld slots are positioned on the rear faces of the leg segment bosses to minimize shear on the plug weld. The link is interchangeable with links in existing chain systems and has improved investment and operating cost characteristics and improved strength and wear properties.

Abstract: Each chain link is punched out of a plastic sheet. The link has a closed form with a central opening and is divided on a line at one end of the opening. The link ends at the dividing line have interengaging shapes preventing separation as long as the link ends remain in the same plane. The plastic material can be flexed to spread the link laterally of the faces in joining one link to another. A slot in each link at the opposite end from its dividing line receives an adjacent link to hold the interlocking ends thereof in the same plane to thus prevent separation. The links are variously shaped to achieve different decorative effects.

Abstract: A segmented band with profile segments, in which the profile segments have a U-profile form, the legs of which form side walls having projecting arms which are equipped with hooks on their ends. The wall section between the arms is intended to hold connecting links, each link having a longitudinal groove intended to hold together the side wall sections, lying between the arms of two neighboring U-profile segments. Closure means are provided to engage in the hooks of said arms which serve to prevent the connecting links for slipping out of the U-profile segments.

Abstract: An expandable metal belt is formed from a plurality of figure-8 shaped sections linked together, each section being formed by weaving a tubular-shaped mesh section from spring metal wire. A coiled wire tensioned spring is passed through the center of the tubular shaped mesh and the ends of the spring are secured to the ends of the tubular mesh section. The opposite ends of the mesh section and tension spring are looped around and brought into abutting relationship and positioned in adjacent parallel relationship to the center of the mesh section to form two loops in the shape of a figure-8. The abutting ends and adjacent center of the mesh are then clamped together by bending a thin metal piece tightly around the adjacent portions of the tubular-shaped mesh section.

Abstract: A flexible link chain in which a plurality of transversely spaced end lugs are connected to each other by a plurality of connecting rods, on which center sheaths are rotatably disposed to rotatably support center links, respectively, which are disposed between the transversely spaced end lugs.

Abstract: A link chain to be used as a watch band, bracelet, or other item of jewelry. The chain includes a string of readily detachable link elements to permit the length of the chain to be quickly and easily adjusted, as desired, by removing or adding link elements at any point along the chain. Each link element consists of a journal link-half permanently hinged to an associated bearing link-half. The journal link-half of each link element includes a solid pintle having two ends, one end being constructed and arranged to be rotatably received in a permanently closed bearing and the other end being constructed and arranged to be rotatably received in a selectively openable bearing at an end of the bearing link-half of an immediately adjacent link element whereby to hingedly join the link elements. The selectively openable bearing has a manually operable closure shiftable between a first and a second position and biased to the first of these positions.

Abstract: This disclosure is directed to expansible linkages for use in the manufacture of expansible bands such as wrist watchbands, identification bracelets, and other articles of jewelry, the sides of which when viewed from the top are provided with attractive configurations, for example, tapered from their ends toward their center portions or vice versa. It is also directed to novel methods of making such expansible linkages.The expansible linkage includes two rows of links and resilient means associated with the links for returning them from expanded to contracted positions. It also includes a series of ornamental top shells attached to the top links. The ends of the top shells extend outwardly from the ends of at least a majority of the top links. Solid inserts are positioned within the outwardly extending portions of the top shells and the outer ends of the combined top shells and inserts are machined to provide any desired configuration to the sides of the linkage when the linkage is viewed from the top.

Abstract: Bracelet, particularly for wrist-watches, comprising a plurality of interarticulated links, provided with means for connection to the wrist-watch body or case, wherein each of the links can be formed from a plate sheet, and wherein each of the links comprise a hollow body having at two opposite ends extensions which are rolled up according to at least a spiral length, the bendings of which are such that one extension of a link can be axially inserted in the extension of the adjoining link.

Abstract: There are provided straps particularly adapted for use with wrist watches, characterised by that the strap comprises a plurality of inner strap elements connected to one another side by side in series, and a plurality of ornamentally designed outer strap elements each having a unique configuration devoid of any bores or through bores for receiving connecting pins as used in conventional similar straps. The strap is so constructed that the inner strap elements are in rigid engagement within associated central transverse grooves of the outer strap elements so as for the whole strap to provide such an appearance as if the outer strap elements were flexibly connected directly to one another without intervening of said inner strap elements therebetween.

Abstract: A hinge band with decorative links articulated about pivot pins includes a plurality of special removable links in order to adjust the length of the hinge band, for example, to fit the arm of the wearer where the hinge band holds a wristwatch or the like. The removable links have decorative insert members and partial collars. Selected links may be released by pivoting and depressing the spring retainers which hold the pins in blocking relation in the partial collars.

Abstract: A bracelet primarily for a watch incorporates at least one link which can be disconnected from a neighbouring link to allow a unit to be added to or removed from the bracelet to alter its length. The unit consists of a link and a pivot element which is pivotally attached by one end to one end of the link and the other end of which has a pair of pivot projections for attachment to another link, e.g. of a similar unit. The said one link has at one end a pair of sockets facing opposite sides of the bracelet and these sockets have slots at their sides remote from said one end to enable the said pair of pivot projections on the pivot element of the unit to be engaged in and disengaged from the sockets. The said one link has a release member pivoted to it for movement into and out of a position in which a portion of the link blocks the slots to prevent disengagement of the pivot projections from the sockets.
