Abstract
Abstract A spray head particularly suited for showers and having a plurality of discharge orifices in which the orifice axes are parallel, the orifices or a selected group of orifices provided with angular deflecting surfaces so arranged that the orifices or the selected group of orifices have D-shaped exits which are so oriented that the spray jets produce a predetermined conical spray pattern rather than coaxially disposed spray jets tending to produce a spray pattern which is essentially cylindrical.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
140 words
A spray head, adapted to be placed over means forming a water distribution cavity for discharge of water therefrom, the spray head comprising: a. a disk member; b. a plurality of discharge bores formed in the disk member; c. a set of deflector means within selected bores adjacent the exit ends thereof, each deflector means forming with the remaining portion of the corresponding bore an asymmetrical discharge orifice; said deflecting means directing angularly a portion of the water passing through the bore to cause impingement thereof against the remaining water passing in the bore as it issues from the discharge orifice to deflect the resulting water jet in angular relation to the axis of the corresponding bore; the set of discharge means being relatively oriented and so proportioned as to cause the water jets to produce a preselected spray pattern.
Claim 2
Dependent Claim

A spray head, adapted to be placed over means forming a water distribution cavity for discharge of water therefrom, the spray head comprising: a. a disk member; b. a plurality of discharge bores formed in the disk member; c. a set of deflector means within selected bores adjacent the exit ends thereof, each deflector means forming with the remaining portion of the corresponding bore an asymmetrical discharge orifice; said deflecting means directing angularly a portion of the water passing through the bore to cause impingement thereof against the remaining water passing in the bore as it issues from the discharge orifice to deflect the resulting water jet in angular relation to the axis of the corresponding bore; the set of discharge means being relatively oriented and so proportioned as to cause the water jets to produce a preselected spray pattern.
Claim 3
Dependent Claim
19 words
A spray head as defined in claim 1, wherein: a. the discharge orifices having said deflector means are D-shaped.
Claim 4
Dependent Claim
18 words
A spray head as defined in claim 1, wherein: a. the disk member defines essentially a spherical zone.
Claim 5
Dependent Claim
34 words
A spray head as defined in claim 1, wherein: a. the disk member includes a marginal rim; and the rim as well as the area surrounded by the rim are provided with discharge bores.
Claim 6
Dependent Claim
35 words
A spray head as defined in claim 1, wherein: a. each bore is cylindrical and each deflector means includes a deflecting surface within the corresponding bore in angular relation to the axis of the bore.
Claim 7
Dependent Claim
23 words
A spray head as defined in claim 5, wherein: a. the deflecting surface defines an angle in the order of 9 1/2 *.
