Abstract
A safety spray wand with a selectively adjustable or interchangeable tip. The wand will selectively provide a high pressure or a low pressure discharge from a discharge tube. The wand has a handle with a pistol grip in combination with a large squeeze trigger. The pistol grip is extended and is molded around a receiving tube that projects downwardly from a discharge tube to thereby form a safety protection guard for an operator's hand while protecting the trigger from accidently being actuated. The receiving tube not only serves as a guard but also as a conduit to which a pressure source is attached and through which the fluid is directed to the discharge tube.
Claims10
A wand for washing vehicles and the like comprising
- a handle having a cavity therein;
- discharge tube means connected into said handle;
- means including a supply tube extending through a receiving cover integral with the handle and intersecting the discharge tube means for supplying fluid under pressure to the discharge tube means;
- valve means including a shaft extending into the cavity and having a reactor member thereon and providing a continuously open, low pressure through the discharge tube means in a released position of the valve and a high pressure flow through the discharge tube means in an actuated position of the valve;
- and
- means for actuating the valve means including a trigger pivotally connected to the handle and extending into the cavity and a cam on the trigger in engagement with the reactor member on the shaft, whereby pulling on the trigger will move the shaft to actuate the valve means.
A wand for washing vehicles and the like comprising
- a handle made of plastic material and having a cavity therein;
- a discharge tube extending from the handle;
- means including a supply tube intersecting the discharge tube for supplying fluid under pressure to the discharge tube;
- seal means in the discharge tube between the cavity and the supply tube;
- valve means providing a continuously open high pressure discharge from said discharge tube and a low pressure discharge from said discharge tube only when the valve means is open, said valve means including a shaft having a reactor member thereon and extending through the discharge tube from the end opposite the handle to the cavity and means operable by pivoting of the trigger to move the shaft and close the valve means;
- and
- means for opening and closing the valve means, said means including a trigger pivotally connected to the handle and extending into the cavity, and a cam on the trigger in engagement with the reactor member on the shaft.
