Abstract

An improved chain-type pipe vise system. The vise includes a base member, at least two V-shaped vise members, and a chain having one end attached to the base member. The other end is designed to wrap around a pipe, and extends downwardly beneath the base member to an attachment assembly. To engage the unattached end of the chain within the attachment assembly, a chain guide unit is mounted to the vise beneath the base member. The unit includes a tubular member having a rod slidably mounted therein. The rod includes an outwardly-extending section which is movable along a slot through the tubular member, and biasing means for pulling the section inwardly. In operation, the outwardly-extending section is drawn back and released. This enables the section to move inwardly, engaging the unattached end of the chain and urging it into the attachment assembly.
