Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
113 words
In a spray iron with a liquid reservoir and sprayer assembly associated therewith of the type having a housing body connected to the iron with liquid passage means therethrough, a check valve and a spreader member in the body and a spray cap abutting the spreader, the improvement in the sprayer assembly to apply spray at different selected liquid flow rates comprising; multiple discrete different-sized spaced orifices in said cap, a swirl chamber in one end of said spreader and offset from the assembly center line, means mounting said cap on the body, and means to bring a single selected orifice into registration over said chamber to provide a given liquid flow rate.
Claim 2
Dependent Claim
113 words

Claim 3
Dependent Claim
53 words
Apparatus as described in claim 1 including means rotatably mounting said cap on the body, means to lock said cap in a selected rotated position to register an orifice centrally opposite said chamber and off the assembly center line to provide said given liquid flow rate, and pump means to actuate said sprayer.
Claim 4
Dependent Claim
29 words
Apparatus as described in claim 2 wherein said swirl chamber is symmetrically shaped and said chamber and said orifices are respectively offset and disposed from the assembly center line.
