Referring. to the drawings the numeral l is usedI to designate in vgeneral the counter ot' a tellers cage having partitions' 9. sepa? rating' said cagev Vfrom adjacent cages and having. oneo'r more ciis'torfers Windows 3. through which business is transacted Ibetween the .teller and customers" of thefban'k. A booth i isprovided outside of each Window 3. Doors 6 are mounted in connection With thefbooth to open and close entrances 7 provided therein. Eachcage is pre1 erably provided Witht'ivo Windows 3 positioned adja cent the cento ofthecage andthe hoo l's'arranged outside Lof said' vvii'idoivs e' sepa'- 'rafed' by apar-ation s' arranged between-trie 110 Windows, but this particular arrangement may of course be modified in various ways to meet the requirements of any particular installation.

A shutter 9 is mounted in connection with each window 3 for opening and closing the same, said shutters being'k provided with mounting elements 11 threaded onto threaded shafts 12 mounted within the upper portion of partitions 13 across the front of the cage. Y Suitable electric motors 14 are mounted. adjacent the ends of the shafts 12 and connectedto said shafts for imparting rotation thereto whereby the elements 11 may be moved longitudinally along the shafts to move the shutters to open or closing yrelation to the windows 3.

Each motor '14 is connected to a suitable vsource of power 15 through a* reversing control switch16 mounted in any suitable llocation conveniently accessible to a teller within the cage but kinaccessible to a person in a booth 4. Current is directed by the reversingswitch 16`through independent opening and closing circuits as showny in Fig. 5 of the drawings whereby the current from the source of power is directed in opposite directions through the motor to cause a rotation of said motor in a direction adapted to obtain the desired movement of the shutter 9 associated therewith. y

The opening circuit consists of a connection 17 extending fromone terminal 18 "of theswitch 16 through a pair of contacts 19 arranged'to be bridged by a contact plate 21,

' to complete a 'circuittherebetween. yFrom the contacts., 19 the current is conducted |througha connection'22, switch 23, and connection`24` to aconnection 26 connectedV to the motor 14 and thence' through'a connection 27 toa return contact l28 of the switch 16. i

'Ihe closing circuit consists of aY connection 29k extending from terminal 34 of the yswitch 16 to the connection 27 whereby currentis directed in opposite direction to and through the motor 14. From the motor the current is Vconducted through the connection 26 and a switch 32 and connection v33 to a return contact 31 of the switch. y

The switches 23 and 32,V which may be of any suitable construction adapted to norvmally close 'the circuit therethrough, are

mountedv in positions adjacent the extreme positions of opposite edges ofthe shutter9 and are arranged to be actuated by the movement of the shutter into' engagement therewith to break the circuit` by virtue of which the shutter isat thevmoment being actuated.

The contacts 19 are resiliently mounted within a partitionof thebooth adjacent the free-edge of the adjacent door 6, preferably at widely spaced points, said'contacts preferably being in the form 'of buttons extending outwardly slightly through the facing of the partition in position to be engaged by the contact strip 21 which is set into the edge of the door in such manner as to engage both contacts and complete a circuit therebetween only when the door is in fully closed position, the purpose of this'arrangement being hereinafter more fully explained.v t

The doors 6 may be made either' of the swinging type as shown in Fig. 1 of the drawings or of the revolving typeas shown in Fig. 2. In either case the doors are arranged to be moved by gravit-y to a normally fully closed position. This is accomplished in the case of a swinging door by mounting the door upony the well known self-closing hinges 35 whereby the weight of the door acting upon inclined edges ofthe hinge butts operates to swing the door closed when said door is swung outwardly from the closed position. In the case of a revolving door I provide a floor plate 36 hav'- ing a central recess 37 `forming a mounting for the lower end of an axis about which the door is revolved. The plate 36 is provided with a fianged edge 38 adapted to form a track for rollers 39 mounted upon the bottom ofthe door, said flange having an undulating upper surface forming low points 41 defining closed positions for the doors. The vflange is provided with convex arcuate track portions 42 between the low points whereby the weight of the door supported upon the convex surface by the rollers will cause the door to move to the nearest closed Vposition as defined by low points in the flange, the rollers resting in said low points until the door is partiallyk revolved to admit a person to the booth. In this form of door,

Vfour door portions are preferably arranged about a. commonfaxis, said door portions being arranged at right angles to each other and the axis so positioned that two of the door portions will act as partitions for the booth at all times' as shown in Fig. 2 of the drawings. A contact strip 2l is mounted within the outer edge of each door portion so thata connection will be made between' the contacts 19 when any door portion is vmoved adjacent thereto.

Bars 43 are pivotally mounted within suitable bearings 44 positioned within the upper portion of the partition 8. Each bar 43 is provided with an extension 46 at one end adapted to be moved into engagement with a notch 47 formed in the upper edge of theadjiacent door whereby said door may be locked in closed position. An extension A48 is formed upon the opposite end of the. bar and `is arranged to be engaged by the adjacent shutter mounting element 11, or other suitable element moving with the shutter when said element is moved to the closed position, for moving the bar pivotally within the bearings 44 and thereby causing the extension 46-to be moved out of engagement with the notch `47 to release thedoo-r. The bar and extension are so mounted that the weight of the extensions will normally cause the extension 46 to be moved downwardly by Vgravity into engagement with the door andtomaintain locking engagement therewitlr until;- released by movement of the shutter against the extension 48 when the shutter is closed.

In operation my invention is as follows: The shutter 9 of any particular window is normally kept closed to protect the teller fron-1- observation and possible attack by robbers. `While in. the closed position the shutter holids the bar 43 in door releasing position so that the door 6 of the booth 4 adjacent such window may be opened to admit a customer into the booth. When a customer enters the booth to transact business with the teller, the teller moves theI switch 16 to engage the contacts 18 and 28', thereby directing current through the shutter opening circuit as indicated by the arrows in Fig. 5 of the drawings to operate the motor 14 in a' direction adapted to move the shutter along the rotating shaft 12 to an openposition as indicated in dotted lines in said Fig. 5; Before it is possible Afor the circuitto be completed tothe motor 14 it is necessarythat the door 6l of the booth be in fully closed' position whereby the contact strip 21`will be caused to bridge the contacts 19.

Aisth'e shutter 9` is moved the extension 4S of the bar 43 Awill beY released an'd the weight of said extension and the extension 46 will cause the extension 46 to drop into the' notch 47 ofthe door thereby locking said dcorin closed position solong as'the shutter remains open. The customer is nowV locked within the booth' and may transact his business' ingprivate with the teller through `the opened window 3of the cage. When the business has'been completed the teller moves the control Lswitch 16 to` engage the contacts 31 and 34 thereby closing the circuit to the motor14 and directing current through said motor in a direction opposite to that resulting in the opening of the shutter. The motor isnow rotatedE and the shutter 9 moved along the shaft 12' to closed position. As the shutter approaches the'` closed position, the" extension 48 of'the bar 43 engagedvand the bar moved to cause theiextension- 46 torelease the doo'rand th-erehy permit the customer to leave the booth.

The switches 23 and V32 placed in the opening andE closing circuits respectively are operated'as above explained bythe movementof the' shutter to either eXtreme position to break thev then actuating circuit. Thuswheir the window is being opened the 4actuatingcircuit will be closed until the instant' the shutter reaches the extreme positienauch operatesithe swift-oh 2`3f'to break the circuit and prevent further nrovement of the i slirutter. rlzhe opening circuit is now broken at the switch 23' and the Closing circuit brolien at the switchlk so that both circuits remain inactive so long as the shutter remains in ope-n position'. When now the switchl isv o}f erated to close the shutter closing circuit, the movement 0f the shutter away fro-1n the switch 23will` release said switch to circuit closing position. The current through the circuit containing the switch 23 will however be mow broken' the switch 16 sol that no current will be directed through the opening circuit connections. The switch 32 operates 'in identical manner to breal the aoy tuatingl circuit when the shutter reaches the extreme position and to restore a closed connection through .said switch as soon as the circuit therethrough is broken at the switch 16. In this manner the lswitches 23 and 32 Vare made to operate in conjunction with the control switch 16 whereby asingle operation of the switch 16 will serve to open`V or close the window as the case may be. a

The slot 47 form-ed in the door 6 to receive the locking bar extension 46 is made suiii'cientlywide to insurev the entrancefof the extension into said notch when' the window is opened, the width of the strip 21 being proportioned to the width ofthe notch 47 in such a way that the notch 47 must necessarily be in position to receive the extension 46 before contact is madebetween the strip 21 andthe contacts 19. The provision is made to insure the locking of the booth door 6 before thejwindow canbe opened.

Freni the above explanation4 it will be noted that the window 3' is closed at `all times when the door 6 i's unlocked, and that the door 6 is locked at all times when the windowB is open'. rIhis arrangement protects the teller .from observation of'persons other than the individiial` within the booth and an attack by a number ofpersons in attempt to commit robbery is madel impossihle. At the samel time,l the person within thexboothis locked inl such a manner that any person attempting to rob-or defraud the bank can be liept imprisoned within the booth while officers are summoned to effect his arrest. The'arrangement thus forms a ine-ans for providingprotection to the teller and guarding against the escape `ofpersons attempting any felonous `act. In addition to the protection afforded, the arrangement affords privacy to the transactions between the'teller and the customers of thebank. Y

The windows'l and booths 4 are preferably arranged in pairsas shown inthe drawings soV that one window may be openedwhile the other window is being closed. Customers will thusbe admitted into the booths alternately and in this manner quicken the condiict o'f v the banks business without de-` reo privacy aiiorded each customer. The number, and arrangement of, the windows and booths however must necessarily be adapted to the requirements of any particular bank.

In order to prevent a customer from being inadvertently locked in the booth due to the failure ofthe -source of electrical power, I provide a recess 51 in the end of each bar 43 to be engaged by a square key adaptedl to be inserted into engagement with said relcess through a small aperture 53 formed in the adjacent panel of the cage. The key parts shown in the drawings may of course be modiiied in'many ways without ldeparting from the spirit of the invention. I therefore do not Wish to restrict myself to the precise constructionshown but desire to avail myself of all modifications which may fall within the scope of thek appended claims. i Having thus described `my invention what I claim as new and desire to secure by Letters Patent is i1.
