Abstract
Abstract A shower head having an oscillating nozzle formed by a helix in a rotating inner tube which is spaced from a stationary outer tube, such spacing being bridged in part by an elongated bar having a slot in registery with an elongated slot in the outer stationary tube. A somewhat square shaped nozzle is formed by the helical groove intersecting the registered slots, and such nozzle osciallates between the ends of the registered slots as the inner tube is rotated. Fluid is delivered into an inlet end of the inner tube for discharge through the oscillating nozzle.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
193 words
An oscillating shower head which includes, in combination, a stationary cylindrical outer tube having a continuous wall substantially enclosing a chamber, an elongated discharge nozzle in the continuous wall of said outer tube, a rotatable cylindrical inner tube having a continuous wall substantially enclosing a passageway, opposite sets of sealing bearing assemblies mounting said inner tube in spaced relationship to the continuous wall of said outer tube, a helical groove in the continuous wall of the inner tube communicating the passageway of the inner tube with the chamber of the outer tube, an elongated bar positioned between continuous wall portions of said inner and outer tubes, said bar having a convex side to engage the inside radius of the outer tube and an opposite concave side to engage the outside radius of the inner tube, an elongated discharge slot in said bar, said bar positioned so that said bar discharge slot is registered with said elongated discharge nozzle in the outer tube, means on said inner tube to engage rotating means, and inlet means for a fluid to be delivered into said inner tube for oscillating discharge through said helix and registered slots.
Claim 2
Dependent Claim
193 words
An oscillating shower head which includes, in combination, a stationary cylindrical outer tube having a continuous wall substantially enclosing a chamber, an elongated discharge nozzle in the continuous wall of said outer tube, a rotatable cylindrical inner tube having a continuous wall substantially enclosing a passageway, opposite sets of sealing bearing assemblies mounting said inner tube in spaced relationship to the continuous wall of said outer tube, a helical groove in the continuous wall of the inner tube communicating the passageway of the inner tube with the chamber of the outer tube, an elongated bar positioned between continuous wall portions of said inner and outer tubes, said bar having a convex side to engage the inside radius of the outer tube and an opposite concave side to engage the outside radius of the inner tube, an elongated discharge slot in said bar, said bar positioned so that said bar discharge slot is registered with said elongated discharge nozzle in the outer tube, means on said inner tube to engage rotating means, and inlet means for a fluid to be delivered into said inner tube for oscillating discharge through said helix and registered slots.
Claim 3
Dependent Claim
47 words
An oscillating shower head which includes the features of claim 1 wherein opposite ends of said inner tube extend beyond opposite ends of said outer Tube, one of said ends being said inlet means, said inlet means including a rotatable coupler element to engage a fluid line.
Claim 4
Dependent Claim
35 words
An oscillating shower head which includes the features of claim 1 above, wherein said elongated bar is at least as long as the length of a helix in the continuous wall of said inner tube.
Claim 5
Dependent Claim
37 words
An oscillating shower head which includes the features of claim 2 wherein the means on the inner tube to engage the rotating means is a pulley fixed to one of the extending ends of the inner tube.
Claim 6
Dependent Claim
35 words
An oscillating shower head which includes the features of claim 4 wherein said pulley is fixed to the extending end having said inlet means for said fluid delivery, and said opposite extending ends being threaded.
Claim 7
Dependent Claim
44 words
An oscillating shower head which includes the features of claim 5 wherein said inlet means includes a rotary coupler element mounted to said threaded end of the inner tube, said rotary coupler element having a non-rotary part for mounting to said fluid delivery line.
Claim 8
Dependent Claim
34 words
An oscillating shower head which includes the features of claim 6 wherein the extending threaded end of the inner tube opposite to the end having said rotary coupler element includes a removable threaded closure.
Claim 9
Dependent Claim
31 words
An oscillating shower head which includes the features of claim 1 wherein said inner tube and elongated bar are formed from plastic material, and said outer tube is formed from steel.
Claim 10
Dependent Claim
131 words
An oscillating shower head which includes the features of claim 8 wherein said plastic rotatable inner tube has opposite ends of reduced diameter, the continuous wall portions whereof are smooth, said reduced diameter smooth wall portions being mounted in spaced relationship to said outer tube by said opposite sets of bearing assemblies, the reduced diameter portions extending from the opposite ends of said outer stationary tube, the terminating portions of said extending reduced diameter portions being threaded, one of said threaded ends having a removable threaded closure, and the opposite threaded end having said inlet means threadably mounted thereto, said elongated plastic bar having its convex side fastened to the continuous wall of said outer tube, and a valve mounted to the wall of the outer tube for flushing the chamber.
Claim 11
Dependent Claim
81 words
An oscillating shower head which includes the features of claim 9 wherein the inlet means include a double socket adapter, one socket of said adapter being threadably mounted to the threaded end of the inner tube, and a rotary joint element being threadably mounted to the other of said threaded sockets, said rotary joint including a non-rotational housing part having an inlet for a fluid line, said non-rotational housing part being freely mounted to a rotatable part of the coupler element.
