SPECIFICATION forming part of Letters Patent No. 683,771, dated October 1, 1901.
Application filed January 29, 1901. Serial No. 45,189. (No nodel.)
ToI @ZZ whom it 17m/y concern):
Be it known that we, Ln ROY EDWARD JOR- DAN and ERWIN JORDAN, citizens of the United States, and residents of Bolivar, in the county of Allegany and State of New York, haveinventedanew and Improved Automatic Polish-Rod Grip, of which the following is a full, clear, and exact description.
This invention relates to improvements in polish-rod grips for raising or lowering valves in oil and gas wells; and the Objectis to provide a simple device by the use of which valves maybe raised or lowered while the pumping machinery is in operation, and therefore with a great saving of time and labor over that of the ordinary methods.
We will describe a polish-rod grip embodying our invention and then point out the novel features in the appended claim.
Reference is to be had tothe accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.
Figure 1 is a side elevation, shown in dotted lines, of a pump mechanism and with a gripping device embodying our invention as applied thereto. Fig. 2 is a top view of the gripping device, and Fig. 3 is a longitudinal section thereof.
The gripping device comprises a yoke l, in which is mounted to swing a gripping-dog 9. The inner end of said dog is transversely curved to conform substantially to the shape of a polish-rod or the like, and it is inclined downward and outward, so as to cause it to grip with different sizes of rods. This inner end, as shown in Fig. 3, is serrated or beveled. The gripping-dog is pivotally connected to the opposite members of the yoke l by means of a removable pin 3. It will be seen that the opening in the dog, through which vsaid pin passes, is somewhat larger than the pin, so that the dog will have a slight lost motion in its gripping operation.
The operationl of the device may be described as follows: In the bottom of an oil-v well on the end of the well-tubing is a Working barrel with two valves. To the upper valve are attached the sucker-rods, which reach to the top of the ground and are attached, by means of the polish-rod a, to Ithe .the tank. This stuffing-box is of course on the tubing. It often happens that sand or other obstruction gets under the valves in the wells, and it is necessary to let the valves down together and to hit one upon the other in order to jar the sand or other obstruction out., and in order to do this the pumping power must be stopped, which necessitates the passing ofa man from the well to the power and then back to the Well and then back to the power to again start it, resulting in a considerable loss of time, especially as the power is located va considerable distance from the well, and this passing to and fro must be done a considerable number of times, as before starting the power the gripping devices ordinarily used must be adjusted on the rods. In using our device the pin 3 is to be removed and the frame or yoke passed around the polish-rod above the adjuster c, and then the dog is placed in position to grip the rod and the pin again inserted. Another gripping device is to be placed on the rod, resting on the top of the stuffing-box e. Now by releasing the set-screw of the adjuster the polish-rod will be permitted to drop down, allowing the valves to fall together. 'When the beam gets down to its lowest point, the dog of the upper gripping device is to be forced tightly into engagement with the polish-rod and lift the valves, when the walking-beam moves the polish-rod upward. When in its highest position, the lower gripping device is to be engaged tightly with the polish-rod and rest on the top of the stuffing-box. This will prevent the rod from dropping downward as the walking-beam again swings down. Then the upper gripping device can be again adjusted on the rod. All these arrangements ot' course are made while the pumping machinery is in operation with a number of Wells. Therefore no time is lost, excepting to the pumping of one well.
The pin 3, it will be noted, is reduced in diameter or has one flat side passing through the opening in the dog. Therefore when it IOO is desired to release the dog from its grip it is only necessary to give said pin ahalf-turn to bring the flat side upward. Then the dog can be readily removed.
It is a frequent occurren ce for gas to enter between the valves in an oil-well and canse the Well to refuse to pump, and in order to set the Well to pumping it is necessary to pull the valves out of the working barrel to let the gas out and allow the barrel to fill with oil. To do this, it is necessary to run a rope over the derrick and use an engine or a team of horses to pull out the valves, thus entailing extra expense, besides loss of production While the valves are being pulled out. Our
device does the work just as well and does it automatically, and it also can be used in place of the two-bolt clamp heretofore employed, which needs to be threaded up by hand.
Having thus described our invention, we
