Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
206 words
A portable, water operated cleaning and sanitizing apparatus removably secured to a mounting board comprising: a. a mixing valve having an inlet fitting, an outlet fitting and a first tee fitting and including a ball check means; b. an inlet hose having one end removably fitted to said inlet fitting and the opposite end to the faucet of a conventional water supply system; c. an outlet hose having one end removably fitted to said outlet fitting; d. a second tee fitting having a first tee leg nipple, a second tee leg nipple and a tee discharge; e. a chemical inlet hose connecting said first tee fitting and said tee discharge of said second tee fitting; f. at least one chemical hose having one end removably fitted to said first tee leg nipple of said second tee fitting, and having the opposite end connected to at least one chemical reservoir; g. at least one valve in cooperation with said at least one chemical hose between said chemical reservoir and said second tee fitting to control the flow of chemical through said chemical hose and said chemical inlet hose to said mixing valve; and h. a spray nozzle in cooperation with the opposite end of said outlet hose.
Claim 2
Dependent Claim
206 words
A portable, water operated cleaning and sanitizing apparatus removably secured to a mounting board comprising: a. a mixing valve having an inlet fitting, an outlet fitting and a first tee fitting and including a ball check means; b. an inlet hose having one end removably fitted to said inlet fitting and the opposite end to the faucet of a conventional water supply system; c. an outlet hose having one end removably fitted to said outlet fitting; d. a second tee fitting having a first tee leg nipple, a second tee leg nipple and a tee discharge; e. a chemical inlet hose connecting said first tee fitting and said tee discharge of said second tee fitting; f. at least one chemical hose having one end removably fitted to said first tee leg nipple of said second tee fitting, and having the opposite end connected to at least one chemical reservoir; g. at least one valve in cooperation with said at least one chemical hose between said chemical reservoir and said second tee fitting to control the flow of chemical through said chemical hose and said chemical inlet hose to said mixing valve; and h. a spray nozzle in cooperation with the opposite end of said outlet hose.
Claim 3
Dependent Claim
55 words
