Abstract
Abstract A pair of open framework type pipe supporting stands are arranged in side by side spaced-apart relation transversely of a work path along which sections of pipe are moved. Each stand includes a top rail pivotally connected longitudinally with the respective ends of the stand and vertically movable at one end to form a horizontal or inclined plane for supporting a joint of pipe when horizontally disposed thereon transversely of the stands. Each stand further includes, at one end portion, a normally depending arm member vertically movable at one end portion between the plane formed by the top rails and an inclined plane slopping away from one end of the stand defined by a pair of skids connected at one end with the respective stand and extending at their other end portion toward a horizontally disposed pipe rack adjacent the surface of the earth for receiving a joint of pipe from the top rails and lowering and depositing the pipe joint on the pipe rack.

Total Claims: 3
Claim 1
Independent Claim
277 words
Pipe handling apparatus, comprising: a pair of upright generally rectangular stand means arranged in spaced-apart relation transversely of a work path along which sections of pipe are to be moved; top rail means comprising an elongated top rail extending transversely of the work path and pivotally connected at one end portion with each said stand means for vertical pivoting movement of its other end portion about a horizontal axis, said top rail means cooperatively receiving and supporting a section of substantially horizontally disposed pipe when deposited thereon; means including a top rail fluid pressure operated cylinder extending between and operatively connected at its respective ends with the respective said stand means and top rail opposite its said pivotal connection for inclining the longitudinal axis of said top rail means with respect to the horizontal to induce a gravity actuated rolling action transversely of the work path on a section of pipe when deposited thereon; arm means comprising an elongated arm disposed transversely of the work path and pivotally connected at one end portion with the pivotally connected end portion of the respective said top rail for vertical pivoting movement of its other end portion toward and away from the surface of the earth and for receiving a section of pipe from said top rails when deposited thereon and lowering and releasing the section of pipe adjacent the surface of the earth; a lateral normally upwardly directed stop secured to said other end portion of each said arm for normally maintaining a section of pipe on said arms; and, other fluid pressure operated cylinders interposed between and operatively connected with each said stand means and said arms, respectively.

Claim 3
Dependent Claim
37 words
The apparatus according to claim 1 and further including: a vertical adjustable sleeve secured to a forward end portion of each said stand means; and, a skid rail supported at one end portion by each said sleeve.
