ABSTRACT:
A drive-up teller window protection apparatus which includes a plurality of downwardly directed nozzles connected to a fluid distribution system supported and housed in a roof structure extending outwardly from a drive-up teller window and positioned a distance above the ground sufficient to allow automobiles to pass thereunder. The fluid distribution system is connected to a fluid reservoir via a conduit having a pressure relief valve and a one-way check valve interposed therein. A source of pressurized fluid communicates with the fluid reservoir via a conduit having a remotely operated valve, a two-way valve, a one-way check valve and a pressure relief valve interposed therein. A second conduit communicates between the two-way valve and the fluid distribution system and includes a one-way check valve interposed therein. An electrical control circuit is disclosed which is connected to a source of electrical potential and includes at least one operating switch between the source of electrical potential and the remotely controlled and operated valve to provide actuation thereof. The fluid reservoir contains a quantity of viscous, adhesive and substantially opaque liquid chemical agent which may be forced from the fluid reservoir by the application of fluid pressure to the fluid reservoir whereby the liquid chemical agent is sprayed from the downwardly directed nozzles onto the front and rear windshields and side windows of a holdup vehicle upon actuation of the remotely controlled valve. The apparatus further includes means for periodically testing the operation of the apparatus and for purging the fluid distribution system and nozzles of liquid chemical agent after operation of the apparatus.
