Abstract
Apparatus for containing and collecting leaks from the stuffing box of a fluid producing wellhead comprising collection means carried by the wellhead below the stuffing box and encircling the wellhead and at least two separate upstanding hollow shapes of such cross-sectional configuration that when they are brought into abutment with one another the volume enclosed within abutting shapes encircles the wellhead and extends from the liquid collection means to above the stuffing box, said shapes having apertured top edge means which form an opening that encircles the polished rod that reciprocates through the stuffing box, the shapes being hingedly engaged so they can be pivoted toward and away from one another for ease of access to the enclosed stuffing box as desired.
