Abstract
Abstract A water valve assembly for mounting on the vacuum return wand of a steam cleaner a water valve of the type having an outwardly biased actuating member which prevents the passage of water in its normal position and permits the passage of water when pressed inwardly. The assembly comprises (a) two mating mounting brackets shaped to receive portions of the peripheries of the vacuum return wand and the water valve, (b) a shaft passing through the mounting brackets between the vacuum return wand and the water valve, (c) a lever arm mounted on shaft between the two mounting brackets, and (d) means for urging the two mounting brackets together so as to firmly grasp the vacuum return wand and the water valve therebetween.

Claim 1
Independent Claim
266 words
A water valve assembly for mounting on the vacuum return wand of a steam cleaner a water valve of the type having an outwardly biased actuating member which prevents the passage of water in its normal position and permits the passage of water when pressed inwardly, said assembly comprising: a. a first mounting bracket having therein i. a first concave surface shaped to receive a portion of the periphery of said vacuum steam wand, ii. a second concave surface shaped to receive a portion of the periphery of said water valve, and iii. a hole passing therethrough between said first and secodnd concave surfaces; b. a second mounting bracket having therein i. a first concave surface shaped to receive a portion of the periphery of said vacuum steam wand, ii. a second concave surface shaped to receive a portion of the periphery of said water valve, and iii. a hole passing therethrough between said first and second concave surfaces; c. a shaft passing through the holes in said first and second mounting brackets; d. a lever arm i. mounted on said shaft between said first and second mounting brackets; ii. one end of which is positioned to actuate the outwardly biased actuating member of said water valve, and iii. the other end of which is positioned so that it can be comfortably actuated by the fingers of a hand grasping said vacuum return wand during use of said steam cleaner; and e. means for urging said first and second mounting brackets together so as to firmly grasp said vacuum return wand and said water valve therebetween.
