Shower head

Claim 2

In a shower head having an elongated body with one end adapted to be threaded onto the end of a water supply pipe and having a passage extending longitudinally therethrough, an annular skirt mounted on the other end of the body and positioned coaxially with said passage and extending axially a distance substantially beyond said other end of the body, a perforate plate member disposed between said other end of the body and the extended end of the skirt to restrict the flow of water from such passage through said skirt, said plate member having an annular series of apertures disposed about the axis of the skirt to divide the flow of water into a plurality of diverging jet sprays, the apertures and skirt being so formed as to direct said sprays into engagement with the edge portion of the extended edge of the skirt, and the entire inner side of the extended edge of said skirt having a smooth continuous surface.

Claim 3

The subject matter of claim 1 wherein the plate member has a dished shape with an annular frusto-conical wall in which said apertures are formed.

Claim 4

The subject matter of claim 1 wherein the end portion of the passage in said other end of the body has a nonround cross sectional shape to provide a socket for receiving a key wrench of the same cross sectional shape to tighten the body onto the water supply pipe.

Claim 5

The subject matter of claim 3 wherein a sleeve is mounted in encircling relation on the portion of the body adjacent said one end to prohibit gripping of the body in that area to unthread the body from the supply pipe.

Claim 6

The subject matter of claim 1 wherein said extended edge portion of the skirt is rounded to cause the jet sprays to further diverge after engaging said edge.

Claim 7

The subject matter of claim 1 wherein the surface of said inner side of the extended edge of the skirt gradually diverges from the axis of the skirt in its outward extension whereby as the sprays engage and pass said edge of the skirt they will diverge into a cone pattern.

Claim 8

In a shower head for attachment to a water supply pipe, a. an elongated body member having one end adapted to be threaded onto the supply pipe, a ball joint at its other end and a passage extending longitudinally through the member, b. a tubular discharge skirt mounted for universal movement on the ball joint and extending therebeyond, c. a disk mounted in the skirt adjacent to the ball joint and having an annular series of apertures for dividing the flow of water through the passage into a series of jet sprays directed outwardly through the skirt, d. said skirt having a frusto-conical interior wall intermediate the disk and the extended end edge of the skirt and positioned to deflect said jet streams into engagement with said end edge of the skirt as they are discharged from the skirt, e. a seal between the ball joint and the disk comprising a pair of coaxially disposed O-rings respectively in pressure sealing engagement with the ball joint and the disk, and f. the total cross sectional area of the apertures being less than the cross sectional area of the passage whereby the water pressure between the disk and ball joint will bias the O-rings in a separating direction to increase the sealing engagement thereof.

Claim 9

In a shower head for attachment to a water supply pipe, a. an elongated body member having one end adapted to be threaded onto the supply pipe, a ball joint at its other end and a passage extending longitudinally through the member, b. a tubular discharge skirt mounted for universal movement on the ball joint and extending therebeyond, c. a disk mounted in the skirt adjacent to the ball joint and having an annular series of apertures for dividing the flow of water through the passage into a series of jet sprays directed outwardly through the skirt, d. said skirt having a frusto-conical interior wall intermediate the disk and the extended end edge of the skirt and positioned to deflect said jet streams into engagement with said end edge of the skirt as they are discharged from the skirt, e. a seal between the ball joint and the disk comprising a pair of coaxially disposed O-rings respectively in pressure sealing engagement with the ball joint and the disk, and f. the total cross sectional area of the apertures being less than the cross sectional area of the passage whereby the water pressure between the disk and ball joint will bias the O-rings in a separating direction to increase the sealing engagement thereof.

Claim 10

The subject matter of claim 7 wherein said O-rings are separated by rigid metal washer.
