Abstract: In a double-pronged chain-shortening claw a safety device for preventing inadvertent release of a chain link supported in a pocket formed between two prongs of the claw. The safety device comprising a locking tongue which can be moved from an inoperative into an operative position in which the tongue projects between the arms of the chain link situated in the pocket.

Abstract: An improved shortening hook for chains with closed elongated links is described. It comprises a slot for receiving a chain link one limb of which is supported by a transverse yoke at the base of the slot. To prevent the chain link from escaping inadvertently from the slot, a locking device fixed to the prong of the hook projects into the mouth part of the slot.

Abstract: A key chain comprises a long chain of oblong links having one link of a length longer than the other links extending outward from a fitting formed with a cross-shaped aperture to permit movement of the chain through the aperture. The aperture has a slot extending out to an edge of the fitting. Only the elongated chain link will slide through the slot. Attached to the fitting is a medallion which may carry an advertising logo, owner identification data or other information or decoration. The outer end of the chain has a finger grip to facilitate grasping the chain to move the chain through the aperture until the elongated link is opposite the slot.

Abstract: A system for securing vehicles to a rail car for transport thereby, with the system including a bi-directional tie-down assembly and a ratchet assembly, or the like, separate therefrom and with the bi-directional tie-down assembly having a double chain in a triangulated configuration for restraining the associated vehicle at the point of engagement. A pivotable hook assembly is provided which allows the selection of one or more hook configurations.

Abstract: An improved safety system for raising, lowering and supporting in an elevated or lowered position, a weighted article from an overhead support. The system includes a link chain passing over a safety pulling member, the link chain having one end permanently connected to the weighted article and the other end permanently connected to an attachment means positioned within reach of a person so that the person may pull the link chain downwardly to raise the weighted article to a desired elevation out of range of the person. The link chain has an improved locking member thereon which may be detachably attached to and locked to the attachment means. The locking member, once installed on the link chain at the proper position, is tamper proof and substantially break proof. The weighted article may be a clothes basket, or other receptacle, or any article in which it is desired to selectively suspend overhead out of reach of a person and then lower within range of a person.

Abstract: An article of jewelry to be worn encircling a portion of the body such as a neck piece or belt is formed from a length of flexible material, two portions of which are engaged by a plurality of hoops disposed on a slide, the hoops being positioned so as to receive the portions of flexible material in frictional engagement of each other, permitting adjustment of the length of flexible material between the two portions so engaged.

Abstract: A chain stopper for round bar iron chain, such as ship's anchor chain, includes spaced, parallel guideways for the horizontal links of the chain and incorporating therebetween a groove for guiding the vertical links of the chain, and having a pair of pawl section receiving recesses formed therein. At least one clamping lever is mounted for pivotal movement about a horizontal axis and includes a pair of pawl sections positioned to receive a vertical link therebetween and to engage a selected horizontal link, the pawl sections engaging the recesses of the guideways to securely lock the chain.

Abstract: An adjustment control device for a chain. The control device includes a body member having a first orifice for slidably receiving the chain and a second orifice extending crosswise of the first orifice for receiving a shackle of a lock. After a chain has been inserted into the body member, the shackle of the lock is inserted into the second orifice between two alternate links of the chain without passing through the link connecting those alternate links to lock the chain in position.

Abstract: To facilitate adjusting the length of a heavy cargo hold-down chain on a transport vehicle and for positively and safely locking the chain after adjustment, a pair of identical slotted plates are employed in reverse overlapping relationship and are detachably secured by releasable fastener means with chain links captured in their slots. The cooperating plate elements are formed to transmit chain tension on a straight linear axis with the releasable fastener means subjected to shearing stresses rather than to bending stresses.

Abstract: The disclosed line releasing clamp receives a line in a saddle portion of the clamp, the line including a stop lug that is caught against the end of the saddle to resist the tension of the line. The saddle in turn is received in, and pivotally attached to, a clip. Upon the tension in the line exceeding a predetermined amount, the saddle slips free of the clip and pivots sufficiently to permit the stop lug to slip from the saddle, releasing the line.

Abstract: A chain anchor which provides for manual quick engagement of a chain with a fixed anchor member, and manual quick disengagement of the chain from said anchor member, both readily, conveniently, and without the use of tools; the structural configuration of such chain-engaging anchor member, together with an associated guard, precluding accidental escape of the chain from the anchor member yet without hindering such manual quick engagement and manual quick disengagement of the chain.

Abstract: This invention pertains to a portable security lock having a sliding fastener and chain that loops around the doorknob stem and a hook that connects to the striker plate and the chain so that when the door is closed, the lock cannot be jimmied or removed unless the portable security lock is removed.

Abstract: A device for adjusting the length of a link chain comprising a shackle or yoke in which the space between the arms is relatively wide except for a narrow portion at the closed end of the shackle. A length of chain extends through the space between the arms and is capable of moving lengthwise when in the relatively wide portion of the space. The relatively narrow portion of the space is wide enough to receive a link of the chain but not wide enough to permit the chain to move in a lengthwise direction. A pivoted keeper is adapted to project into the relatively wide portion of the space to retain the chain in the narrow portion and thereby prevent it from moving lengthwise.

Abstract: A slide locking assembly for use with chain members of jewelry articles such as necklaces, bracelets and the like comprising a housing for receiving said chain members, said housing comprising inner and outer case sections, means for maintaining separation between the chain members, and spring means for urging portions of said chain members into contact with the housing to produce a frictional drag thereon, wherein the component parts of such an assembly may be easily hand assembled by snap-fit locking engagement of the mating case sections.
