| 276 | Apparatus for constantly rotating casing during installation | US778914 | 1977-03-18 | US4135586A | 1979-01-23 | Martin D. Cherrington |
| An inclined drill rig is disclosed with attached rotatable power tongs for use in practicing a process for the installation of underground casing. The underground casing is usually installed coaxially to a pilot string disposed about an invert arcuate underground path underneath an obstacle, such as a river. The underground casing is installed in discrete segments from a slanted drill rig unit including a car traveling on an inclined ramp. The traveling car on the inclined drill rig ramp crowds and rotates each pipe segment sequentially into the ground from a rotating table. When the last pipe segment attached is fully advanced into the ground, it is clamped at power tongs located at the front of the ramp. These power tongs apply torque to rotate all the casing in the ground without crowding the casing. | ||||||

| 278 | Method and apparatus for pipe joint locator, counter and displacement calculator | US724729 | 1976-09-20 | US4110688A | 1978-08-29 | John M. Bailey |
| The invention is a novel method and apparatus for counting pipe joints, passing through a bell nipple, going downhole and uphole by sensing, at spaced apart positions along the nipple utilizing magnetic fields, for the presence of a joint. Each sensor develops signals as the joint passes it and a logical network determines which direction the pipe joint is traveling, adds a plus count to the joint counter for joints going downhole and subtracts a minus count from the joint counter when a joint is sensed coming uphole. Another logical circuit converts the joint count to a stand count, and the negative signals from the stand count trigger an adder network to introduce a binary number to a numeric read-out display, which number is indicative of pipe displacement per stand, withdrawn from hole. | ||||||
| 279 | Drilling assembly | US578677 | 1975-05-19 | US4074774A | 1978-02-21 | Cicero C. Brown, deceased; by Joe R. Brown, executor |
| A drilling machine and relatively small mast are mounted on a pivotal support which permits the drilling machine, mast and drill pipe employed in the assembly to be inclined as required to drill a non-vertical bore hole. The drilling machine is preferably a fluid pressure-operated snubber device which includes a stationary lower gripping head and a vertically reciprocable, upper gripping head operable for rotating drill pipe and for running the drill pipe into and out of the well bore. An internal drill string anchor carried by a traveling block suspended in the mast engages and supports the upper end of the drill string extending from the snubber and also provides drilling fluids to the string. A rotatable seal and support assembly in the anchor maintains a fluid seal and permits the drill pipe to rotate relative to the non-rotating traveling block. The anchor is equipped with slips which grip the internal surface of the drill string and are positively moved into and out of gripping engagement with the drill string by hydraulic controls. A spring bias is provided on the slips to urge the slips into their gripping position and means are provided which increase the gripping force of the slips in response to an increase in the forces tending to separate the drill string from the anchor. | ||||||
