Abstract
Abstract A housing adapted for enclosure in a pool wall has a chamber connecting between an inlet conduit and a discharge jet tube mounted in a hollow ball retained by a face plate across the housing chamber. A spring biases a semispherical cup against the ball containing the discharge jet tube to secure the ball in movable sealing contact with a socket in the face plate. Pressure on a protruding portion of the ball frees the ball for repositioning to redirect the jet tube. A threaded throat in the chamber receives bushings with varying orifices to change liquid flow from the jet tube.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
168 words
An angularly adjustable liquid discharge jet comprising a body, a body inlet, a body chamber, a transverse wall between the inlet and the chamber, an aperture in the transverse wall, means for adjusting the wall aperture size; a face plate at the opposite end of the body chamber from the inlet, an annular wall defining a seat in the face plate, a hollow jet tube holder movably seated in the face plate seat, a directional tube fixed in the holder to move therewith; an apertured bias cup in the chamber, a spring compressed between the transverse wall and the bias cup loading the cup toward the face plate, and a concave wall in the cup receiving the jet tube holder movably therein, said spring-biased cup forcing said jet tube holder into sealing movable contact with said face plate; said jet tube holder being externally adjustable while the face plate is in place by being axially displaceable against the spring load to interrupt the seal with the face plate.
Claim 2
Dependent Claim
168 words
An angularly adjustable liquid discharge jet comprising a body, a body inlet, a body chamber, a transverse wall between the inlet and the chamber, an aperture in the transverse wall, means for adjusting the wall aperture size; a face plate at the opposite end of the body chamber from the inlet, an annular wall defining a seat in the face plate, a hollow jet tube holder movably seated in the face plate seat, a directional tube fixed in the holder to move therewith; an apertured bias cup in the chamber, a spring compressed between the transverse wall and the bias cup loading the cup toward the face plate, and a concave wall in the cup receiving the jet tube holder movably therein, said spring-biased cup forcing said jet tube holder into sealing movable contact with said face plate; said jet tube holder being externally adjustable while the face plate is in place by being axially displaceable against the spring load to interrupt the seal with the face plate.
Claim 3
Dependent Claim
35 words
Apparatus in accordance with claim 1, wherein the means for adjusting the aperture size comprises a bushing with an orifice and an extreme outside diameter less than the inside diameter of the outlet directional tube.
Claim 4
Dependent Claim
86 words
Apparatus in accordance with claim 1, wherein the means for adjusting the aperture size comprises internal thread forms in the wall aperture, an externally threaded bushing having an outside diameter less than the inside diameter of the directional tube, at least one flanged sleeve having a central orifice and adapted to seat in the bushing, said bushing having a downstream radial slot, and a torque tool adapted to extend through the tube and rotate the bushing by engagement with the slot to remove the bushing externally.
Claim 5
Dependent Claim
26 words
A fluid discharge jet in accordance with claim 1, wherein the body inlet comprises inner and outer annular walls each adapted to receive a fluid conduit.
