A debarking chain having passing links; the passing links being substantially rounded in order to permit the passing links to pass through adjacent links such that the orientation of the passing link relative to its adjacent links can change at random in order to randomly distribute the wear and stress from any impact of adjacent or next to adjacent links on the passing links so that the overall wear life of the present debarking chain is extended over similar chain with elongated, oblong links of the prior art. The invention also includes a debarking drum having a plurality of debarking chains having at least one, preferably a plurality of passing links, as well as a debarking device having such a debarking drum. The debarking device preferably includes a chipping device and a method of using the same.

Debarking chain with passing links

A debarking chain having passing links; the passing links being substantially rounded in order to permit the passing links to pass through adjacent links such that the orientation of the passing link relative to its adjacent links can change at random in order to randomly distribute the wear and stress from the impact of adjacent or next to adjacent links on the passing links so that the overall wear life of the present debarking chain is extended over similar chain with elongated, oblong links of the prior art.

One-way chain for an aircraft tie-down, as well as a method of making one-way chain. The method preferably includes the steps of providing an unmodified welded chain having a plurality of welded links; feeding the unmodified chain into an automated shaping machine constructed and arranged to shape the welded links in separate shaping events; and individually shaping the welded links to form shaped links in a series of separate shaping events that shape the respective welded links so that a first width of a forward end of the respective shaped link is narrower than a second width of the greatest planar width of a rearward end of the respective shaped link; such that the forward end is sized to fit into a link receiving receptacle of a screw-type binder mechanism and the rearward end will not fit into the link receiving receptacle.

Method of making one-way chain

The present invention is a safety hook ( &prime;) having a wire spring latch ( ). The wire spring latch ( ) is a wire loop pawl. The safety hook ( ) is made of a heavy gauge wire form material, which is preferably bent only to form first and second ends ( ), a chain link securing end ( ) and a hook opening end ( ), respectively. The wire loop pawl ( ) is preferably a rod of elastically deformable material, bent to form an open loop ( ) and bent-over ends ( ) about which the pawl ( ) pivots with respect to the body ( ) of the safety hook ( ) when the latch ( ) is deformed and forced away from a distal end ( ) of the hook opening end ( ) of the safety hook ( ). The bent over ends ( ) of the wire loop pawl ( ) are not coaxial. The wire loop pawl ( ) may be deformed in such a way as to open the safety hook ( ), but the latch ( ) is heavily spring biased up against an inside ( ) of the distal end ( ) of the safety hook ( ).
