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.
