Claim 10

An eyeball fitting for delivering water to a swimming pool, said eyeball fitting being disposed at the discharge end of a water supply line and having an inlet in communication with said water supply and an outlet in communication with said swimming pool, said eyeball fitting comprising: an eyeball having a substantially spherical outer surface; an axial passage extending through said eyeball, said axial passage being defined at least in part by a first tapered surface and a second tapered surface, said first and second tapered surfaces being oppositely oriented relative to the axis of said passage so as to form a minimum transverse dimension of said passage at the juncture of said first and second tapered surfaces; an axially extending insert adapted for placement within said eyeball passage, said insert including a passage therethrough having an inlet end and an outlet end for allowing water to pass through said eyeball, said insert including an outer wall defined at least in part by a reducing tapered surface disposed toward said inlet end and continuously expanding tapered surface disposed toward said outlet end, said reducing and expanding tapered surfaces being oppositely oriented relative to the axis of said insert so as to form a minimum transverse dimension of said outer wall therebetween, with said expanding tapered surface providing a transverse dimension to said insert outlet end slightly greater than the minimum transverse dimension of the axial passage through said eyeball; said insert being adapted for push-on engagement with said eyeball by placement of said insert within the axial passage through said eyeball and forcing said outlet end of said insert through the minimum transverse dimension of said eyeball passage so as to securely engage said insert within said eyeball passage; and retainer means adapted for placement at the end of said water supply line and including a substantially spherical inner surface for receiving said eyeball and cooperating with the substantially spherical outer surface of said eyeball for allowing said eyeball to be positioned at variable angular orientations.

Claim 11

An eyeball assembly for use in an eyeball fitting, comprising: an eyeball having a substantially spherical outer surface; an axial passage extending through said eyeball, said axial passage being defined by an inner wall including a reducing portion and an expanding portion, said inner wall including a surface of minimum transverse dimension disposed between said reducing portion and said expanding portion; and an axially extending insert adapted for placement within said eyeball passage, said insert including a passage therethrough having an inlet end and an outlet end for allowing fluid to pass through said eyeball, said insert including an outer wall defined at least in part by a continuously expanding surface extending between the outlet end of said insert and an area of minimum transverse dimension of said insert outer wall spaced from said outlet end of said insert, with said outlet end of said insert having an outer transverse dimension slightly greater than the minimum transverse dimension of said eyeball passage; said insert being adapted for push-on engagement with said eyeball by placement of said insert within said eyeball passage and forcing said outlet end of said insert through the minimum transverse dimension of said eyeball passage so as to securely engage said insert within said eyeball passage.
