Independent Claim
158 words
A spraying device comprising in combination a mounting plate, means on said mounting plate for removably and adjustably supporting an aerosol container, said container including a depressible valve member at one end thereof, a plunger slidably mounted on said plate and including an inner end and an outer end, spring means normally urging said plunger into inoperative position, a rotatable cam member mounted on said plate beneath said plunger and above the depressible valve member of said aerosol container, a portion of said cam member normally disposed in the path of said plunger, a leaf spring mounted on said plate between said cam member and said depressible valve member whereby upon the exertion of axial force upon the outer end of said plunger causing slidable movement thereof, the inner end of said plunger strikes a portion of said cam member to rotate it into engagement with said leaf spring, forcing said spring downwardly against said depressible valve member.
