Abstract An apparatus for transferring pipe between pipe racks and the drilling rig floor including a stationary trough located below and extending towards the drilling rig and a movable, inclined trough aligned with the stationary trough having one end supported on the drilling floor and the other end powered to move between a lower position for transferring pipe to and from the stationary trough and an upper position for transferring pipe to and from the drilling floor. Two pair of racking legs extending between the pipe racks and the fixed trough are provided. Each log has a cradling lug which moves up and down the leg powered by a hydraulic cylinder, thereby lifting the pipe along the leg. Further, each leg is able to pivot in two directions about a pivoting structure. The pipe when moving in the troughs is held at one end by a shovel member which is engageable by the buggy which travels along the stationary trough and is also engageable by the carriage in the inclined trough. The carriage in the inclined trough may comprise either a chain driven carriage having a latch portion engageable with a latch portion of the shovel member or may comprise two pair of arms which close around the shovel member and subsequently move the shovel member, and thus the pipe, along the inclined trough. Two pair of dumping arms are positioned beneath the fixed trough at a location adjacent the racking arms. These arms powered by fluid actuated cylinders pivot about a point on the stationary trough so that their outer end extends through openings in the stationary trough thereby engaging a pipe and moving the pipe out of the stationary trough to the racking arms. An operator's station is pivotally mounted on top of the stationary trough.
