670,900, daten March 2c, 1901.
Application filed June 30,1900. Serial No. 22,108. (No model.)
To all whom, 731 may concern:
lie it known that I, DAVID W. KENNEY, a citizen of the United States, residing at St. Marys, in the countyof Pleasants and State of Vest Vi rginia,haveinvented certain new and' useful Improvements in Oscillatingr Stuffing- Boxes; and I hereby declare the following tohe a full, clear, and exact deseriptionof the invention, such as will enable others skilled in the arttc which it appertains to make and use the saine.
My invention relates to that class of stuft'- ing-hoxes which are'nsed ferpacking whatis known as the polished rod of a pumping oil-well.
The object of my invention is to provide an oseillatingstuliing-box which will entirely overcome the Wearol said bex and rod by reducing the friction to a minimum. I eccomplish the above result as shown in the aecompanyin'g drawings, in which- Figure l is a side elevation showing my invention, and Fig. 2 is n vertical sectional View of the same.
In the drawings,A. represents a socketpvhich is formed in two sections e and i and rigidly secured together by bolts c. .lhe lower section b is threaded at the bottom for the purpose ot' screwing it onto the top ol the tubing d. l Within thesockel Aiea hollow ball B, the upper end of which is provided with threads for screwing the stulling-box l) therein.
.By the use of my invention the\iriction is entirely overcome, with the exception ol the poi nt wherethe polished rod C passes through the stuffing-box, whereas by the use of the old method ol' connecting the stulling-box direct to the topol" the tubing the friction and wear on the stuiling-box and polished rod, cznsed by the movement ol' the walking-boem, are so l great as to cause the rod to cut or the box to 1 Wear in a short time, so as to allow the oil tospray out over the derriek-floor.
It will be readily understood that the walking-'beam in making its stroke causes the polished rod to pull against one side of the stuft'- ing-box when it is traveling upward and likewise against the opposite side on the downward movement, as thestuingv-box is firmly secured to the top of the tubing', while by the use of my device the stelling-box D and ball B are allowed to rock within the socket A with the Side movementotI the polished rod, thereby overcoming all weenin the box and on the rod. The oscillation of the hall li in the socket A is caused by the variation of the end of the arm of the walking-beam, to which the rod is attached from a right line, and this depends upon the distance between the point where the rod is attached to the pivotal point of the arm, and whatever, distance it may be the rod must spring oryield just that much between the sLulling-boxand tho pump-piston.
Anydesired lubricant may beappled at the top et' the socket for keeping the parte oiled.
,Any suitable packing e may be employed t'or forming a tight joint between the two seetions ofthe socket.
Having described my invention, what I claim is- An oscillating smiling-box, consisting of a socket fx, a hollowpball l5, within the socket havingan elongated portion which is threaded for the pui-'pose of receiving the stellingbox proper-D, and the lower part of the socket being screw-threaded to the top of the tubing, all substantially as shown and lfor the purM poses described.
