TO ALL WHOM IT MAY CONCERN: BE IT KNOWN, that I, J. T. TEAGUE, a citizen of the United States of America, residing at 802 Duncan, Longview, in the County of Greg State of Texas, have invented certain new and useful improvements in PIPE-HANDLING APPARATUS, of which the following is a specification: ABSTRACT OF THE DISCLOSURE As a preferred embodiment of the invention disclosed herein, a winch is stationed to one side of an oil field derrick and a cable spooled on the winch extended over a pipe rack and- secured at a convenient location above the derrick floor. A pair of spaced pulleys or carriages are independently pulled along the extended portion of the taut cable by a pair of selectively- controlled winches respectively carrying a cable or wire coupled to the carriages. Pipe carriers are dependently coupled to the carriages and operatively arranged for carrying a pipe laid between the carriers in a nearly-horizontal position as the selectively- controlled winches move the carriages along the extended cable between the derrick floor and the pipe rack. The pipe section is selectively raised or lowered over the pipe rack by operating the first winch to either tighten or slack off on the extended cable.
