Abstract
A split tube containing a lubricant is engaging a bicycle chain. The lubricator tube is carried by the chain during the initial chain operation until the tube end contacts a barrier surface on the chain drive mechanism. The barrier may be the pivoting idler arm, the derailer mechanism, or a portion of the bicycle frame. The device brings the lubricant in intimate contact with the chain allowing the use of semi-solid, liquid, and solid-solvent mixture of lubricants.

In combination with a power-transmission chain, a lubricating device which comprises:
- a container partially enclosing a lubricant, said container having a transversal bore slidingly engaging the chain;
- wherein said container comprises two mating half sections joined about a plane intersecting said bore;
- and
- means to impede one direction of movement of the container when the chain is in motion.
A chain lubricating device in combination with a chain and means for moving the chain, said device comprising:
- a split case element shaped and dimensioned to slidably hang from said chain, said case element comprised of at least two removable sections;
- means for attaching said sections to each other;
- a lubricant contained within said case in intimate contact with said chain;
- and
- means for limiting one direction of sliding motion of said case element banging on said chain.
