Abstract: A swiveling joint system for a horse head on a pump jack includes a working beam, a worm drive, a horse head member, and at least one locking pin. The swiveling joint system improves access to parts of the well because the horse head member can be swiveled out of position instead of being completely disassembled. The locking pin holds the horse head member in alignment with the working beam. When the locking pin is removed, the worm drive controls the swiveling of the horse head member in either direction towards either side of the working beam. The worm drive has a worm gear attached to the horse head member so that movement and position of the horse head corresponds to movement of the worm gear. The horse head member and working beam are rotatable relative to each other on a pivot pin, which can be connected to a lubricator.
