  • Patent number: 5865895
    Abstract: Syrup spray systems for producing frozen dessert cones include a manifold block defining a bore therethrough. At least one nozzle assembly is provided in fluid communication with the bore of the manifold block and having an actuator stem reciprocally movable between an inoperative condition (in which liquid syrup in the bore is prevented from being sprayed into an awaiting cone), and an operative condition (in which liquid syrup in the bore is sprayed into an awaiting cone). A control cylinder moves the actuator stem between the operative and inoperative conditions and is coupled removably to the actuator stem. In such a manner, the manifold block and the at least one nozzle assembly thereof may easily be removed from the control cylinder to permit repair and/or replacement thereof.
