| 81 | Drill pipe spinner | US117272 | 1987-11-05 | US4774861A | 1988-10-04 | William R. Hamilton; Harry D. Hebard |
| A drill pipe spinner having a body with an open throat for receiving a drill pipe. A pair of cylindrical driven rollers are mounted on the body for rotation about a vertical axis. A pair of pressure arms are pivotally mounted on the body for rotation about a primary pivot pin. A pair of secondary pressure arms are mounted on the primary pressure arms, for rotation relative to the primary pressure arm about a secondary pivot pin. A pair of cylindrical pressure rollers are mounted on the secondary pressure arms, for holding the drill pipe against the driven roller. A pair of piston and cylinder assemblies exert force on the secondary pressure arms, to cause the secondary pressure arms to rotate. The moment arms between the piston and cylinder assemblies and the primary pivot pins are shorter than the moment arms between the piston and cylinder assemblies and the secondary pivot pins. Springs, mounted between the primary and secondary pressure arms, cause the primary pressure arms to rotate with the secondary pressure arms, about the primary pivot pins, until the pressure rollers have contacted the drill pipe. A plurality of sprag clutches prevent back rotation of the primary pressure arms about the primary pivot pins. | ||||||
| 82 | Line wrap power tongs | US838459 | 1986-03-11 | US4715253A | 1987-12-29 | Thomas E. Falgout, Sr.; William N. Schoeffler |
| A power tong has two powered rings mounted on the tong frame for independent rotation, one ring, a reel carrier, carries a plurality of spring rewind line storage reels. Independent lines extend from each reel and each line is anchored to the second powered ring. An open gap, or throat, extends to the tong center to receive pipe when the lines are all recovered into the reels. The reel carrier ring is rotated to wrap the lines in a spiral pattern around pipe. The second ring is driven to pull the lines and the reel carrier ring is braked to apply tailing tension to the lines but does then turn in sympathy with the second ring to turn pipe. To recover the lines, the second ring is stopped and the reel carrier ring is driven in the direction to allow lines to return to the reels as they unwrap from the pipe. | ||||||

| A motor driven serpentine chain circulating device for spinning drill pipe into engagement for final tightening by other devices. Jaws are closed and locked to position chain for embracing pipe before the chain tension is applied. Chain tension does not depend upon exact positioning of the jaw closure. Optional sequencing system speeds operation. | ||||||

| A well pipe spinner having two body parts carrying rollers adpated to engage a pipe at different locations about its periphery and grip and spin the pipe by rotation of one or more of the rollers, with the two body parts being mounted by pivotal connections for swinging movement about two spaced axes respectively to grip and release the pipe, and with an adjustable connection attaching the two pivotal connections together for relative lateral adjusting movement to shift their pivotal axes toward and away from one another for gripping different sizes of pipe. | ||||||
| 85 | Suspension of pipe spinner | US351462 | 1982-02-23 | US4425827A | 1984-01-17 | Lawrence E. Wells |
| A pipe spinner is provided which includes two parts carrying rollers and mounted by two pivotal connections for swinging movement between a closed position in which the rollers grip and drive a well pipe or the like and an open position releasing the pipe, with an adjustable connection attaching the two pivotal connections together for relative lateral movement to shift the two pivotal axes toward and away from one another for gripping different sizes of pipe, and with the spinner including a hanger or support structure attached to the mentioned adjustable connection and adapted to be suspended by a line or other element in a manner suspending the entire tool through the adjustable connection. | ||||||
| 86 | Drill pipe clamp | US115911 | 1980-01-28 | US4324157A | 1982-04-13 | Michael D. Soutsos |
| A clamp for drill pipes includes an hydraulic motor adapted to drive a gear head which is keyed to a sprocket engaged to a sheave chain. The sprocket and the associated equipment are mounted between two plates which are also provided with an hydraulically operated slide for advancing two rollers. It is these rollers that, by their advancement, enlarge or shorten the effective sheave chain loop, the sheave chain passing over idlers towards the end of two hinged arms or jaws which are conformed to receive the drill pipe. Formed at the end of each jaw are bearing seats each adapted to receive a bearing cap which engages ball bearings in corresponding bearing races supporting the center shaft of two turning sprockets around which the chain is looped. Each of the bearing races includes an enlarged periphery and it is between this periphery and the chain loop that the pipe is engaged. In this manner pipes of various sizes may be clamped on the interior of the jaws and the rotation of the hydraulic motor can then drive the pipe. | ||||||
| 87 | Pipe spinner | US967586 | 1978-12-08 | US4221269A | 1980-09-09 | Ray E. Hudson |
| A pipe spinner for spinning drill pipe as used to dig deep wells includes a yoke with a torque arm. Three self-contained rotary hydraulic motors having urethane coated rollers on the exterior thereof are mounted upon the spinner, one in the central area of the yoke and one each on a swing arm pivoted to the end of the legs on the yoke. Hydraulic fluid for the three motors is supplied and removed axially thereof. The hydraulic fluid conduits are made flexible at the pivots. | ||||||
| 88 | Powered pipe wrench | US903722 | 1978-05-08 | US4178817A | 1979-12-18 | John Gibson |
| A powered wrench for connecting links of pipe, the wrench including means for operatively engaging a length of pipe with a power driven toothed roller to rotate the pipe in a desired direction. The wrench includes idler rolls for applying supporting and smoothing pressure to the pipe responsive to the actuation of pressure applying means carried by the wrench. | ||||||
| 89 | Pipe-spinning apparatus and method | US615597 | 1975-09-22 | US4099429A | 1978-07-11 | Ernest D. Hauk |
| According to the present apparatus and method, a silent chain having an inversely-bent internal portion is caused to be in direct pressure engagement with the external cylindrical surface of a drill pipe or other object to be spun. The chain is mounted on at least five sprocket wheels, one of which is a drive wheel adapted to rotate about a movable axis which may be locked in any desired adjusted position. The pressure between chain and pipe is caused to be sufficient to spin the pipe but insufficient to injure the pipe or prevent relative sliding movement when the joint is completed. A spring is provided to absorb shock on completion of the joint, and to cooperate with the relative sliding movement in preventing injury to the apparatus or to any user thereof. The chain is caused to encompass a very large section of the diameter of the pipe, regardless of variations in pipe diameter. At least for some sizes of pipe, the pivot points of the apparatus are so arranged that the chain tension operates to maintain the jaws closed instead of attempting to open the same, whereby to minimize the possibility of the tool "climbing off" the pipe. A pneumatic circuit is provided to insure that adequate pipe-engaging pressure is maintained despite loss of air pressure due to operation of a pneumatic spinning motor. | ||||||
| 90 | Tool for connecting and disconnecting well pipe | US678403 | 1976-04-19 | US4023449A | 1977-05-17 | George I. Boyadjieff |
| A combination tool including a power slip, spinner unit and torque wrench, all mounted movably to a common support structure adjacent a well. The assembly is operable to first support the lower of two successive sections of pipe in the power slip, and then turn the upper section relative to the lower one to screw the pipes together or apart, with the major portion of the rotation being effected by the spinner, and the final high torque make-up rotation or initial joint breaking rotation being produced by the torque wrench. | ||||||
