Myriad harmony assistant keygengurut. 126,986 3 Claims. 286-15) This invention relates to polish rod stuffing boxes.
In one specific aspect it relates to a self-aligning stuffing box for use with polish rods in a sucker rod actuated oil well pump assembly. In another aspect it relates to a selfaligning polish rod stuffing box that adjusts its position to conform with the irregularities of movement of the polish rod during pumping operations. In the art of polish rod stuffing boxes a large proportion of the failure of such stuffing boxes is due to misalignment of the polish rods during pumping operations. Another reason for failure of such stuffing boxes is due to the frequent tightening of the packing gland by the pumper even when tightening is not necessary. An object of this invention is to provide a polish rod stufng box which is self-aligning and adapted to compensate for irregularities in motion of the polish rod. Another object of my invention is to provide a polish rod stufng box in which that portion containing the packing is self-aligning.
Another object of this invention is to provide a polish rod stuffing box in which that portion of the box containing the packing moves in a lubricating reservoir. Still another object of this invention is to provide a pressure lubricated self-aligning polish rod stumng box. Still other objects and advantages of my invention will be apparent upon reading the following description which when taken with the attached drawing forms a part of this specification. In the drawing, Figure 1 is an elevational view, in section, of my self-aligning stuffing box assembly.
Figure 2 is a diagrammatic representation of a tubing head assembly including the self-aligning stumng box and lubricator in operative relationship. Referring now to the drawing and specifically to Figure 1, reference numeral II refers to a cylindrical housing member which contains the floating gland assembly I2 of my invention. At a point near the top of the cylindrical housing II is attached by welds I1 or other means, a flange member I5. This flange member I contains bolt holes I5 for use in attaching an upper flange or cap member I3. This cap ange member I3 is generally round in shape and has bolt holes I4 that align with bolt holes I6 in ange I5. Bolts 25 when inserted rigidly attach the cap fiange to the main body of the packing as- 2 sembly.
