BLEEDING DEVICE AND TUBING JAR.
' Application filed July 18, 1923. Serial No. 652,328.
T 0 all whom it may concern:
Be it known that we, ANDREW J. BARN- HART and Cnrrnnnow N. TRIMMELL, citizens of the United States, residing at Plaoentia, in the county of Orange and State of California, have invented new and useful Improvements in Bleeding Devices and Tubing Jars, of which the following is a specification.
Our invention relates to jarring device or well drilling tubing, and a purpose of our invention is the. provision of a device of extremely simple, durable, and efiicient' construction by which a drill stem or tubing can, through a manipulation of the tubing from the top of the well, be converted intorelatively movable units to allow reciprocation of the upper unit in effecting a hammering or jarring of the lower or drilling carrying unit whereby the freeing of the drill tube can be effected.
It is also a purpose of our invention to provide a jarring device which includes means b which the bleeding of the u per drill tublng unit can be automatically e ected upon movement of the jarring device to active position, thus draining the tubing, and thereby permitting the more ready reciprocation of the tubing.
Although we have herein shown and will describe only one form of jarring device embodying our invention, it'is to be understood that various changes and modifications may be made herein without departing from the spirit of the invention and the spirit and scope of the appended claims.
In the accompanying drawings Fig. 1 is a View showing in vertical section one form of jarring device in applied position with respect to two adjacent sections of a drill tube.
Fig. 2 is a view showing the jarring device in side elevation and in applied position to the drill tubing, but inactive position to permit reciprocation of the upper section of the drill tubing.
Referring specifically to the drawings in which similar reference characters refer to similar parts, our invention in its present embodiment comprises a hammer element H, and an anvil element A, the former being rigidly connected to the upper section 15 of any two adjacent sections of a drill tubing by means of a connecting sleeve .16 having threaded engagement with the tube section 15 and with the upper ends of the hammer element so that the confronting ends of the tube are securely held in abutting relation. The anvil element is rigidly connected to the lower tube section 17 through the threaded connection 18, and the anvil element is made of an upper section 19 and a lower section 20 detachedly connected by means of an over-lap joint 21.
The elements A and H are both of tubular form and the internal diameter of the former is sufiicient to allow of free reciprocating movement thereof upon the hammer element. Normally, the anvil element is secured against movement'with respect to the hammer element by a reduced upper end 21 connected to the hammer element by a lefthand screw-threaded connection 22. The uppermost position of the element A upon the element H is defined by the sleeve 16, it being noted that the reduced end 21 abuts the lower end of the sleeve 16. The lowermost position of the sleeve 16 is defined by an annular shoulder 23 formed on the hammer element at the upper end of the threaded connection 22.
The hammerelement H is provided at its lower end with a. head 24 which exceeds in diameter that of the element and which constitutes the hammer of the jarring device. This head 24 is adapted-to strike against a head 25 formed interiorly of the element- A and which constitutes the anvil of the jarring device, it being understood that the head 25 is also of annular form to correspond to the head 24. It will be particularly noted that element is reduced in internal diameter to provide a seat or shoulder 26 which constitutes an abutment for the hammer head 24 when the latter is in its lowermost sition.
For the purpose of allowing the leeding or discharge of liquid from the jarring device and that portion of the well tubing above the device, the hammer element H is formed with perforations 27 which are exposed when the anvil element is-disengaged, as clearly shown in Fig. 2.
In practice the anvil element A is normally held against movement by virtue of its threaded connection 22 with the hammer element H so that the jarring device serves to provide a ri 'd connection between the sections 15 and 1 of drill tubing. The drill tubing may now be reciprocated in the usual manner to effect operation for the drill tool within the well. Should the drill tool for the lower end of the anvil any reason become locked against movement within the well, a freeing of the tool can be effected by' rotating the section 15 in a clockwise direction so as to unscrew the threaded connection 22 and thereby effect a release of the anvil element A. It will be understood that all of the other threaded connections are right-hand screw threads so that rotation of the tubing will be ineffective to disconnect the threaded connections during the disconnection of the connection 22. With the anvil elements A released, it will gravitate from" the position shown in Fi 1 to that shown in Fig. 2 wherein the anvil head 25 reposes upon the hammer head 24. The upper tube section15 is now free to be reciprocated to impart a corresponding movement to the hammer head 24 so that a vertical jarring of the anvil element A and the tube section 17 connected therewith is now efi'ected. This movement effects a .vertical jarring of the anvil element; A and the tube section 17 connectedtherewith with the result that aloosening of the tool within the well is efl'ected.
It will. be Iioted that ment A is rel within the device and the tube sections above the device is free to pass out of the perforations 27 thus relieving the tubing and device of the weight of the liquid and thereby facilitatin the reciprocating of the tube.
What we 0 aim is:
1. A lower drill tube \section, an anvil element screwed upon the drill tube section when the anvil eleand having an enlarged cylindrical bore with an annular shoulder at the upper end of the bore and forming a head and having eased, any liquid, contained a screw thread above the shoulder, at
h the e bore e the shoulder and adapted to there being a screw thread upon the hammer elementjto fit the screw thread of the anvil element and hold the parts rigid, a coupling sleeve screwed upon the upper end of and an upper section screwed into the. coupling sleeve so that the parts form a rigid portion of a drill tubing, and so that when the lower part is held and the upper part rotated the hammer element will be screwed: out of the anvil element to serve as a jar.
2. In drill tubes, a combined tube connecter and anvil and hammer forming a drill jar comprising a connecting non-per forated tubular sleeve screw threaded on a lower tube section, said sleeve having a lower section and an upper section joined by a lap screw joint, said upper section having an annular anvil face on its inner upper end, a tubular hammer having an annular hammer member at its lower end-and secured at its upper end to an upper drill tube by a threaded sleeve connection, and reverse threads on said hammer member adjacent its upper end engaging with threads on the; upper end of said anvil connecter member whereby, by an unscrewing action, the upper and lower drill tubes are separated and by a reciprocating movement of the upper tube a jarring action is obtained.
In testimony whereof we have signed our names to this specification. CLITHEROW N. TRIMMELL. ANDREW J. BARNHART.
