Due to the resiliency of the legs, the U-shaped supporting member may easily be swung to and from operative position.
This construction and arrangement of parts make it possible to swing the entire jet-dispersing assembly out of the way of the jet so that a straight high velocity stream can be employed at the option of the operator, and this has been found to be a particularly advantageous feature in such applications as lire protection where it may be desirable to have either type of spray instantly available; also for watering lawns, washing cars, etc.
While we have shown and described desirable embodiments of the invention it is to be understood that this disclosure is for the purpose of illustration and that various modifications and changes may be made without departing from the spirit and scope of the invention as set forth in the appended claim.
We claim:
A fog nozzle comprising a tubular member having a bore tapering from its receiving end to its discharge end, the outer face of said tubular member being provided with diametrically opposite recesses, a pin-like jet-dispersing member having an active surface of approximately the same size and shape as the discharge opening, and means for supporting said jet-dispersing member in operative position with its active surface in alignment with said bore and spaced from said discharge opening a distance not less than one-half nor more than three-times the cross-sectional dimension of said discharge opening so that a jet issuing therefrom impinges on said active surface to produce a homogeneous fog of predetermined shape, said means consisting of a generally U-shaped member the closed end of which carries said jet-dispersing member and the legs of which are pivotally secured to the body of said tubular member so that their intermediate portions snap into said recesses when said jet-dispersing member is swung to operative position.
