Abstract: A split attachment is provided from two substantially identical half pieces each having projections and slots adapted for wedgedly joining the respective halves together for securing tightly about an article. Means on the split half pieces may be deformed against the surfaces of the article to prevent sliding of the attachment or a loose movement between the gripped articles when the attachment is used to join two articles together such as the rods of a brass bed headboard.

Abstract: An articulated bracelet comprises a chain of visible tubular links of oval section, adjacent pairs of which are connected by joining links hookably engaging in rectangular openings in the tubular links. Each adjacent pair of joining links are retained by mutual coaction of complementary hook-like end parts in a hollow element, whereby links can be added or removed by hand.

Abstract: A rivetless chain having solid side bars and a slotted center link interconnected by a removable pin having end lugs associated with locking recesses in the side bars. The side bars are forged and the solid construction thereof prevents accumulation of particles of material therein. The rivetless chain is useful in various orientations such as in overhead conveyors, trolley conveyors and in many other installations where a chain having large dimensions, such as a pitch of several inches, is employed.

Abstract: A chain link, a series of which can form a chain, the links having hook means at one end and a transverse bight at the other end whereby the hook means of one link can be detachably connected to the bight of an adjacent link. The hook means are formed by the ends of the legs of the link being turned back upon themselves so as to define a relatively narrow opening between the ends of the hooks and their respective legs. A transverse slot-like recess is formed in the legs adjacent the bight and at the end of the link opposite that on which the hook means are formed. The slot-like recess defines a narrower leg portion which is of a thickness less than the opening between the ends of the hooks in the legs so that in order to detach the chain links from one another, it is necessary to fold the links together so that the narrower leg portion can be slipped transversely through the relatively narrow opening of the hook means. This interlocking construction prevents inadvertent disengagement of the chain links.

Abstract: This disclosure relates to a jointed link band comprising a plurality of links, each link including a pair of arms, a first of said arms having a pair of projections projecting transversely to the longitudinal axis of said band. A second of said arms having recesses therein receiving said projections. A retaining member is provided for preventing the disassembly of adjoining links by motion of any two links transverse to the longitudinal axis of the band.

Abstract: An improvement is disclosed in connector devices such as those comprising connector links for use with chain and cable. Two mating end pieces are provided such as chain half-links, each having a transverse bore therein to receive a connecting pin. The connecting pin has a diameter slightly less than that of the bore in the end pieces so that the end pieces are freely rotatable about the pin and relative to each other. Each end of the pin is chamfered and a split-ring collar is provided for each end of the pin so that once the pin is inserted through the aligned bores in the end pieces, the split-ring collars can be driven onto the respectively opposite ends of the pin to hold the pin in place.

Abstract: A conveyor chain articulatable in two planes transversely of each other and normal to the direction of chain advancement. The chain has alternating link types. Alternate drive links have a body center defining a center aperture for receiving the cog of a sprocket wheel in driven relation and have end hooks portions which curve transversely toward the body center in spaced relation. Alternate attachment links have a perimeter body defining toroidal outer loops for removably engaging the hook portions of adjacent drive links and have a center section for engaging a transversely extending conveyor flight.

Abstract: A coupling link for field/factory assembly of chain lengths and/or attachments thereto; and/or for repairing broken chains or to couple lengths of chain together whenever desired; said coupling link comprising two half link units each of which comprises an overlay/underlay assembly of two or more relatively nested complemental-configured half-link shaped members all of which are stamped out from sheet/plate stock and formed into generally U-shaped sectional form, the paired components thereof being complementarily shaped and internested together. Thus, where the coupling link is under tension loadings the bowed portions of contiguous members yield into mutually reinforcing shapes. Said half-link shaped members have apertured terminal ear portions interdigitally mounted upon a common interconnecting pin; thereby spreading the operational shear loads on the pin.
