Abstract
A puller mechanism for moving the end of a pipe into a collar mounted on a second aligned pipe in order to assemble a pipeline. The mechanism is constructed to be used in conjunction with heavy pipes, such as, for example, Johns-Manville Transite asbestos/cement pressure pipes. The mechanism includes a first semi-circular yoke assembly which is clamped to the pipe, and a second yoke assembly whose legs straddle the collar. The second yoke assembly is pivotally coupled to the first yoke assembly by a pair of arms on opposite sides of the first pipe. An elongated operating handle extends outwardly from the bight section of the second yoke, and the handle is used to turn the second yoke about a fulcrum. Two L-shaped members supported at the ends of the leg sections of the second yoke engage the rim of the collar to constitute the required fulcrum, so that when the handle is turned the end of the first pipe is pulled into the collar. A plurality of elongated guides may be provided which extend from the first yoke along the first pipe and collar to guide the end of the first pipe into the collar. The L-shaped members may be replaced by spike members which extend into the ground to form the desired fulcrum.
