Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
173 words
A washing machine outlet device comprising: an outlet box; spaced sides on said outlet box; a back on said outlet box; means to secure said outlet box to a wall; a trough having a bottom, an upwardly extending frontwall, an upwardly extending backwall, and upwardly extending sidewalls, said bottom having a passage formed therein; means securing sidewalls of said trough to said sides of said outlet box; a tube having a drain opening extending therethrough and having an overflow passage; means securing said tube through said passage in the bottom of the trough such that said overflow passage is positioned in said trough and the lower end of the tube extends below said bottom of the trough; liquid level sensing means in said trough; switch means connected to said sensing means; a socket connected to one side of said switch means to receive a plug on a washing machine electrical cord; and conductor means connected to the other side of said switch means, said conductor means being connectable to a source of electricity.
Claim 2
Dependent Claim
173 words
A washing machine outlet device comprising: an outlet box; spaced sides on said outlet box; a back on said outlet box; means to secure said outlet box to a wall; a trough having a bottom, an upwardly extending frontwall, an upwardly extending backwall, and upwardly extending sidewalls, said bottom having a passage formed therein; means securing sidewalls of said trough to said sides of said outlet box; a tube having a drain opening extending therethrough and having an overflow passage; means securing said tube through said passage in the bottom of the trough such that said overflow passage is positioned in said trough and the lower end of the tube extends below said bottom of the trough; liquid level sensing means in said trough; switch means connected to said sensing means; a socket connected to one side of said switch means to receive a plug on a washing machine electrical cord; and conductor means connected to the other side of said switch means, said conductor means being connectable to a source of electricity.
Claim 3
Dependent Claim

Claim 4
Dependent Claim
18 words
The combination called for in claim 1 with the addition of a splash guard about said overflow passage.
Claim 5
Dependent Claim
46 words
The combination called for in claim 1 wherein said liquid level sensing means comprises: a float; and means to connect said float to said switch means arranged such that accumulation of liquid in said trough moves said float to a position wherein the switch is opened.
Claim 6
Dependent Claim
