Abstract
Abstract This invention relates to a filtering and aerating jet filter comprising a filter cartridge formed by a stack of grooved washers positioned in a chamber for flow of water under pressure through the stack of washers and out of the outlet of the device. The outlet has an associated port for entry of air into the filtered jet of water to aerate the latter. The chamber in which the stack is positioned is designed to contain a deodorizing substance to remove odors from the water and the device is designed so that it may readily be disassembled and also may be cleaned without disassembling by having a reverse flow of water therethrough.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
158 words
A filtering and aerating jet breaker comprising a hollow body having an inlet at one end and an outlet at the other end, means for connecting the inlet to a faucet, a filter cartridge positioned in said hollow body and extending axially thereof, said hollow body encompassing said cartridge and being spaced therefrom to define a chamber, said filter cartridge comprising a stack of juxtaposed washers each having radiating grooves on at lest one surface thereof and a central opening therein, said openings defining a central passageway closed at its upper end adjacent the inlet and open at its other end, through which liquid may flow from the inlet into said hollow body and through said grooves into said passageway to the outlet, a plurality of air inlet ports adjacent said outlet for admission of air from the exterior into the jet of water passing through said cartridge, and a charge of granulated deodorizing chemicals in said chamber.
Claim 2
Dependent Claim
158 words
A filtering and aerating jet breaker comprising a hollow body having an inlet at one end and an outlet at the other end, means for connecting the inlet to a faucet, a filter cartridge positioned in said hollow body and extending axially thereof, said hollow body encompassing said cartridge and being spaced therefrom to define a chamber, said filter cartridge comprising a stack of juxtaposed washers each having radiating grooves on at lest one surface thereof and a central opening therein, said openings defining a central passageway closed at its upper end adjacent the inlet and open at its other end, through which liquid may flow from the inlet into said hollow body and through said grooves into said passageway to the outlet, a plurality of air inlet ports adjacent said outlet for admission of air from the exterior into the jet of water passing through said cartridge, and a charge of granulated deodorizing chemicals in said chamber.
Claim 3
Dependent Claim
90 words
The combination set forth in claim 1 in which said hollow body comprises a central portion in the form of a frusto-conical member of transparent material, a cup-shaped connecting member positioned on one end of said central portion, a hollow ferrule positioned on the other end of said central portion and a stirrup having a cross member resting against said cup-shaped connecting member and having the ends of its legs detachably connected to said ferrule, resilient means being positioned in said ferrule releasably to retain said elements in locked position.
Claim 4
Dependent Claim
49 words
The combination set forth in claim 2 in which said central member is substantially frusto-conical in shape having a reduced diameter portion at its lower end, a ring encompassing said reduced diameter portion, said ring having a plurality of circumferentially spaced air passageways therethrough, said ferrule encompassing said ring.
Claim 5
Dependent Claim
57 words
The combination set forth in claim 3 in which a mesh screen is positioned against the end of said reduced diameter portion, a second mesh screen is positioned at the end of said ferrule and said resilient member is a coil spring positioned in said ferrule and reacting against said screens to retain the latter in position.
