Abstract
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.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
251 words
In a protective construction for use with a drive-up window in a first wall having inner and outer sides and having a teller's counter spaced inwardly from the inner side of the wall, the improvement comprising: a second wall spaced from the outer side of the first wall a distance sufficient to allow passage of an automobile therebetween; a roof structure extending between said first and second walls above the drive-up window and positioned a vertical distance above the ground sufficient to allow passage of an automobile thereunder; a plurality of downwardly directed nozzles mounted in said roof structure in spaced relation, said nozzles being aligned such that fluid streams emanating therefrom impinge on the windshield and windows of an automobile positioned thereunder adjacent the drive-up window; fluid distribution system means for communicating with said nozzle; fluid reservoir means for communicating with said fluid distribution system means; liquid chemical agent means disposed within said fluid reservoir means for passing through said fluid distribution system means and said nozzles and forming fluid streams emanating from said nozzles and impinging on the windshield and windows of an automobile to obscure vision therethrough and mark the automobile for identification; means for applying pressure to said fluid reservoir means to pass said liquid chemical agent means from said reservoir means and through said fluid distribution system means and said nozzles; and control means for alternately permitting and preventing the application of pressure by said means for applying pressure in response to control signals applied thereto.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
20 words
The apparatus as defined in claim 1 wherein said control means is characterized further to include an electrically actuated valve.
Claim 4
Dependent Claim
95 words
The apparatus as defined in claim 2 wherein said control means is characterized further to include an electrical circuit interconnecting a source of electrical potential and the electrically actuated valve, said electrical circuit including switch means intermediate a source of electrical potential and the electrically actuated valve for closing the circuit between the source of electrical potential and the electrically actuated valve to cause said electrically actuated valve to open and, alternately, for opening the circuit between the source of electrical potential and the electrically actuated valve to cause the electrically actuated valve to close.
Claim 5
Dependent Claim
89 words
The apparatus as defined in claim 3 wherein said electrical circuit includes at least one additional switch means intermediate the source of electrical potential and the electrically actuated valve for closing the circuit between the source of electrical potential and the electrically actuated valve to cause said electrically actuated valve to open and, alternately, for opening the circuit between the source of electrical potential and the electrically actuated valve to cause the electrically actuated valve to close, each said switch means being operable independently of the other switch means.
Claim 6
Dependent Claim
