A roller chain-connecting tool comprises a narrow elongated body containing a lengthwise-extending threaded rod journaled in and extending through both ends of the body to hexagonal bolt heads for rotating the rod. A chain hook is mounted on the threaded rod by means of an internally threaded block which moves lengthwise along the tool\s body when the rod is turned. In one embodiment, a second chain hook is mounted on one end of the body and the rod is threaded in only one direction. In another embodiment, the second chain hook is mounted on another internally-threaded block and the threaded rod has approximately one half threaded in each direction from its center. The chain hooks or jaws are gently curved toward one another and are tapered so as to fit both small and large gauge roller chains, the large chains being at least twice the size of the small chains. The sides of the body are spaced laterally apart from the threaded rod and from the sides of the internally-threaded block or blocks so that one or both hooks can rotate through a small angular range for easy manipulation of the tool in awkward locations.

A chain-connecting tool for pulling the opposite ends of a chain toward one another for interconnection, the tool comprising: an elongated body having spaced ends; a threaded rod mounted for axial rotation in the body, the rod having end portions journaled in and extending through each end of the body and rigidly supported thereby; rotating means for rotating said rod independently of the body; a pair of chain-engaging means for engaging said chain ends; and mounting means threadedly mounting at least one of the pair of chain-engaging means on the rod for movement therealong toward the other chain-engaging means when the rotating means is actuated to rotate the rod for pulling said end links toward one another; the mounting means being spaced laterally inwardly of said body a distance enabling the mounting means to be rotated relative to said body through a predetermined angular range for positioning the chain-engaging means on the ends of said chain.
