16 Claims. (Cl. 109-49) This invention relates to improvements in drive-in banking apparatus and, more particularly, to new deposit units and new combinations thereof with power operated driving mechanisms and with drive-in tellers windows.

Drive-in banking apparatus is used for thedirect transaction of banking business with occupants of motor vehicles. The apparatus makes use of a window in a wall of a bank building or other enclosure occupied by a teller. The teller is able to see a customer through the window and to communicate orally with the customer through a suitable speaking system. Transfers of deposits, withdrawals, bank books or other articles are made by use of a movable deposit unit provided in a wall opening near the window. The teller moves this unit by hand from an inner or closed position in which it is accessible only from within the enclosure, to an open position where it projects from the wall. for access by a customer occupying a vehicle at the enclosure.

The deposit units are usually constructed heavily, so as to be protected against vandalism, and their operation is burdensome to the teller. The teller not infrequently leaves the deposit unit in its open or projecting position after the completion of a banking transaction. in many installations this creates a hazard of damage to approaching vehicles or to the projecting deposit unit itself, especially where the drive-in apparatus embodies a sliding deposit unit or tray that projects forward to a position quite near to a vehicle for easy access by a driver.

One of the objects of this invention is to provide an improved drive-in banking apparatus having a deposit unit for article transfers which is moved horizontally between closed and projecting positions under the desired control of the teller but without requiring any objectionable physical eiiort on the part of the teller. A further object is-to provide such an apparatus by which the movable deposit unit is automatically returned from an outeror customeraccessible position to an inner or protected position if the attendant should fail or' forget to return it, so as to eliminate the hazards above mentioned;

A more specific object of this invention is to provide an automatically operated apparatus of the type last mentioned with which the teller has complete control of the positions and movements of the deposit unit and can cause it to remain at its outer position without being alfected by the automatic retracting mechanism, and also can cause it to be retracted at any moment without awaiting the action of that mechanism.

Another object of the invention is to providea driving mechanism for a horizontally slidable deposit unit of a (irivedn banking apparatus, wherein the unit is mechanically locked at the limits of its movements, i. e., in its closed and its projected positions, so as to prevent movemeat of the unit away from either position by any forces er-zcept those exerted by the driving mechanism.

A further object of the invention is to provide a power operated driving mechanism for the deposit unit in a drivein banking apparatus of the character described by which injury to fingers or hands or to the apparatus itself is prevented when movement of the deposit unit is obstructed by a person outside the apparatus or by any hard obstruction.

Still another object of the invention is to provide a drivein window construction including a horizontally movable deposit unit or tray which forms an article receptacle accessible to the teller and inaccessible to a customer when the unit is in closed position, and which becomes open to the customer as the unit moves to a projecting position but is then so covered that the teller is protected against injury by a-person outside the window enclosure, and also against objectionable drafts in cold weather.

Still another object is to provide such a construction by :hich the teller can inspect the contents of the deposit unit as it moves inward and when it is in closed position before uncovering the receptacle to remove its contents.

A further object is to provide such a construction in which most of the top area of the article receptacle is covered by a movable cover controlled by the teller and giving him full access to the receptacle when theunit is in closed position, and in which a door at the front end of the unit moves open, as the unit moves to open position, so as to give a customer clear access to the article receptacle. it is also an object to provide the unit with such an end door which assures an open position at which it will guide articles placed upon it into the enclosed space of the receptacle.

According to this invention, a drive-in window apparatits is provided with a horizontally movable deposit unit for article transfers between customers in vehicles and a banltteller occupying an enclosure comprising a transparcut Window structure, and the deposit unit is connected with a motor driven mechanism. controlled by the teller which is operable to move the unit away from or back to the window structure to effectuate the article transfers. The driving mechanism holds and locks the unit in its outer or projected position where the motorist has access to it until the teller or a timer control actuates the mechanism to return the:unit to a retracted. position in which it is accessible onlytotheteller. The mechanism also locks the unit in the retracted: position. Thus the deposit unit, even though of heavy construction, is operated with ease by the teller who has only to press a button or pull a lever to initiate itsmovements; and it need. never-be left exposed in the projected position for a period. longer than may be needed for the conduct of a bankingtransaction.

For convenient access by customers to the article receptacle of the depositunit; the deposit unitis provided with a self-acting'relatively movable door or end closure which opens and closes as the unit is. moved. away from and back to the window wall. The teller has access to the; receptacle by' a movable" protective cover member which is locked in a closed state in all positions of the unit except its fully retracted position. The protective cover is usually composed principally of a transparent panel .to permit observationof the interior of'the receptacle by the teller.

Other objects, features and advantages: of the invention will become apparent from the followingdetailed description 'andthe accompanying drawingssliowing an illustrative embodiment of the invention.

Figure 4 is a transverse vertical section taken on line 4- -4 of Figure 2; m

Figure is a cross-sectional view of a clutch forming part of the driving mechanism, taken on line 5-5 of Figure 4; and

Figure 6 shows a diagram of a suitable wiring circuit and of motor and control elements for controlling the operation of the apparatus.

Figure 1 illustrates a drive-in banking .window, generally indicated at 1, arranged in a wall 2 of a bank building or similar enclosure-located adjacent curb 3 of a driveway (not shown) by which motorists can drive to a position directly in front of the window for the transaction of banking business. The apparatus includes a bulletresistant transparent window panel 4 and a speaking system 5 in a metal casing or frame 2a, permitting visual and oral communication, respectively, between a teller within the enclosure and a customer in a vehicle at the window. In order to transfer articles from customer to teller and vice versa, a deposit unit 6 is moved in an opening 7 in the frame 2a between a closed or retracted position in which the unit is accessible only to the bank teller and an outer or projected position in which the unit extends forward from wall 2 and is accessible to the customer.

Referring particularly to the construction of the deposit unit 6 as seen in Figures 2-4, two substantially rectangular, vertical longitudinal sides 8 support a transverse member 9 between them which extends from the rear of the unit along the top edges of the sides 8, is dipped at 10 where it forms a back panel, and is sloped upwardly at 11 as it approaches the front edges of. sides 8 to form a dished receptacle 12 having a bottom panel for receiving articles to be transferred. The lower front corners'of sides 8 are beveled at 13 at an inclination coinciding with the slope of portion 11. The receptacle 12 of the unit carries and is bordered by a front end door 14 and a top cover 15, the front door being locked in a closed position when the unit is fully retracted, as will be described hereinafter, to safeguard against vandalism. The top cover is held closed in all positions of the unit except its fully retracted position so as to protect the teller against drafts and against any access through the unit to the interior of the window enclosure by a person outside the enclosure.

The front door 14 is hinged at 16 to the deposit unit 6 along the front edge of the transverse member 9 and has a skirt 17 which extends below the hinged connection and below the edge of opening 7 when the door is closed, and also when the door is fully opened. As the unit is moved outward from wall 2, the door 14 swings open under the force of gravity until the skirt 17 butts against the beveled corners 13 of sides 8 in parallel relation to the upwardly sloped portion 11 of member 9, as indicated in broken lines at the left side of Figure 2. Thus, when the unit is in the outer position, the door is fully open and the interior of the receptacle is accessible to the customer. The door 14 closes automatically as the unit is retracted, because the edge of skirt 17, tapered at 17a, then butts against the casing 2a so as to swing the door around the hinged connection 16 to a vertical closed position. It will be seen that the construction of drawer 12 guards its contents against being blown away by winds and that the opening at the front end of the drawer, exposed by movement of the door 14, could be controlled to secure any desired degree of exclusion of winds or air currents from thisend opening. For example, door 14 can even be kept normally in its closed position through control of the forces respectively acting upon its upper portion and its skirt 17.

The top cover has a bullet-resistant transparent panel 18 to permit observation of the interior of the receptacle 12. This panel is encased in a metal frame 18a which is pivotally supported at 19 in sides 8 of the deposit unit 6 at a point spaced inwardly from the vertical position of door 14 a distance exceeding the thickness of frame 2a,

so that the cover is freely swingable about its pivots to an open position, as shown in broken lines in Figure 2, when the deposit unit is in a fully retracted position. It will be apparent that as the unit is projected from the window, the cover 15 slides under the frame 2a and is locked against opening movement by the adjacent horizontal edge of the frame. The cover is manipulated by the teller by a handle 20 secured thereto.

A counter-balancing weight or spring may be provided to hold the cover 15 in an open position after release of the handle by the teller. One form of such a counterbalance is illustrated in the drawings wherein a coil spring 21 exerts a counter-balancing force on the open cover 15 through an arm 22 fixed to the cover at an angle thereto. The arm 22 has one end secured to the cover at pivotal point 19 and the other end secured to one end 23 of the coil spring 21. The coil spring has its other end 24 fixed to a lower portion of one of the sides 8, and the spring extends over a roller 25, also fixed to the same side 8, for properly directing the counterbalancing force.

A guard 26 may be provided along the top edge of opening 7 on the outer surface of the frame 2a, to provide protection against Weather and for purposes of safety. A rubber seal 27 is provided inside frame 2.4 between the edge of opening 7 and the top of cover 15 to seal the space between the glass panel 18 and the top of opening 7.

The deposit unit 6 is mounted on slides 36 fixed by rivets 37 to base 38 of a housing 39. The base 38 may be integral with the frame 2a, as shown, and the bottom plate of the housing 39 may be Welded, as indicated at 39a, to the frame 211 of the window structure. The housing has a partial top cover 40 which forms a counter for the bank teller. To mount the unit on the slides 36, the sides 8 are secured to roller guides 41 by brackets 42 which carry the guides 41 and are welded to sides 8 as at 43; and the guides 41 are slidably mounted on slides 36 by rollers 44. Thus, the deposit units can be moved the length of slides 36 relative to the housing 39.

The deposit unit is moved forward and retracted relative to window 1 by a teller controlled, power operated driving mechanism having successive projecting and retracting phases of movement. This mechanism, generally indicated at 45, includes a releasable clutch 46 and connecting linkage 47 between the clutch and the deposit unit. An electric motor 48 drives clutch 46 through reductiongearing 49 and a clutch shaft 50, the latter being vertically supported in a bracket 51 fixed to a platform 52 by an angle member 53. The motor 48 and reduction gearing 49 are also mounted on platform 52 in any convenient manner, while the platform 52 is secured to base 38 as by bolts 54.

The motor 48, gearing 49 and driving mechanism 45' are so assembled in the housing 39 as to fit in the rear portion of the deposit unit when it is in its inner position, and as to move the unit horizontally along slides 36. To move the unit horizontally, the rotary clutch 46 is mounted on vertical clutch shaft 50 at right angles thereto and drives connecting linkage 47 in a horizontal plane parallel to the plane of the clutch.

As more clearly shown in detail in Figure 5, the clutch 46 comprises driving and driven disc members 55 and 56, respectively, which are mounted face to face on a hub 57 drivingly connectedto the shaft 50 by a key 58. The driving disc 55 is secured to a nut 59 by cap screws 60, only one of which is shown, and the nut and driving disc assembly is threaded on the hub 57. The driven disc 56 is freely mounted on hub 57 between the driving disc and a flange 61 of the hub and is held in place against the driving disc by a washer 62. Member 55 rotates member 56 by a yieldable connection comprising balls 63 arranged in openings 64 of the driving disc member, which balls areurged into recesses 65 of the driven disc member 56 by leaf springs 66.

The. springs. 66 are. so tensionecl. as. to, cause. rotation of disc 56by the disc 55 tu' der normal operating loads but to permit yielding of the balls 63 and over-running of, the driving disc with respect. tothe driven disc should a force greater than the normal. load be applied tothe driving mechanism, such. as. obstructions blocking; the

movementof the deposit unit. Each of the recesses 65.

is at a different radial distance fromthe axis of the discs, so that the driven disc 56 will always have a certain position relative to the driving disc when the clutch is operative.

The driven disc 56 acts as a crank for a link 73 which is pivoted at one end, as by pivot 74a, to across bar 74 fixed between the sides 8,0f the deposit unit, and. is pivoted. at its other. end, as. at 75, to an arm 76,.which is, fixed to and extends radially from the driven disc 56. The pivot 75 on. the radial arm isrotated with disc 56 in a circle of. which the. diameter corresponds tothe desired range of movement of the deposit unit.

When the deposit unit is either in its outer position or its retracted position, the pivot 75 is in line with pivot 74a and the fixed axis of. disc56, Thus, in either position the unitis locked against movement other than rotation of arm 76 and pivot 75.

The operation of the drivingmechanism is controlled through limit switchesLSl and LS2 which have contacts 67 and 68, respectively, in the electric control circuit t diagrammed in Figure 6. Switch LS1 has a spring -biased arm 69 to control normally. closed, contacts 67, which arm lies in the path of rotation of switch- operatingcams 71 and 72 secured to and spaced. 180 apart on the driven disc 56 of the clutch 46. Switch LS2 has a spring-biased arm 70, to control normally. closed contacts 68. Arm 70 lies in the path of rotation of cam 71 only. In the fully closed position of the deposit unit cam 71 depresses both of the arms69 and 70 so as to hold open the contacts of both limit switches, while in the fully open position of the deposit unit cam 72 holds arm 69 depressed to open the contacts of LS1, and the contacts of switch LS2 are closed.

The control circuit of Figure 6 includes, in addition to the automatically operated switches LS1 and LS2, two manually operated switches or pushbuttons 78 and 79 and 'a time delay switch TS, which may be of conventional construction, all connected. electrically with. current sup ply lines L1 and L1 and the driving motor 48. The push? buttons 78 and 79 are located in a convenient position-for manual actuation by the teller, say on the inner end wall of housing 39, as shown in Figure 2.. Supply line L2 is connected directly to one lead of the motor 48 and to-one lead of a resistance coil 81 forming a heating element of the time delay switch TS. The other lead of the motor is connected to a normally open contact 8i! of switch TS, to a contact of pushbntton 78 and to a contact at 67 of limit switch LS1. The other contactsof LS1 and. push.- button 78 are connected to current supply line. L1, and this line is also connected to one contact of pushbutton '79, the other contact of which is. connected to a contact of limit switch LS2 and, through LS2 when it is closed, to the coil 81 and the other normally open contact 80 of time switch TS.

The operation of the illustrated embodiment will be apparent from the foregoing descriptionfbut maybe sum.- marized as follows: s 6

When a motoristdesiring banking service drives to the window 1, the teller observes the customer through panel 4 and may speak with him through the sound system including grill 5. A transfer of articles being desired, the teller pressespushb'utton 78, whereupon motor 48 is en.- ergized, clutch ti starts turning clockwise, and the resulting motion of linkage 47 moves the depositunit along its supportin slides toward its outer or projected position. After approximately 10 of rotation of the clutchdisc56, cam 71releases the switch arms 69 and 70, allowingconmom and as or the "two li'mi't'switchesLsl and ps2 to close. The. closing of LS1, establishes a holding circuit to motor 48, allowing pushbutton 78 to be released, and the outward movement of the deposit unit still continues. The closing of, contacts 68 of limit switch LS2 energizes the heating element 81 of the timer TS. As the deposit unit reaches its outer position, cam 72 has rotated about 180 and depresses switch arm 69 to open the contacts 67 of limit switch LS1, thereby deenergizing the motor 48 and causing the deposit unit 6 to come to rest in its outer position.

Meanwhile, as the deposit unit moves away from wall 2, the front door 14 swings open under its own weight until skirt 17 butts against the beveled corners 13 of the side walls 8, thus opening the receptacle of the unit so that the customer easily may deposit articles in the r ceptacle. The top cover 15 of the deposit unit meanwhile has been locked in closed position by the overlying edge of frarneia. At its outer position the deposit unit 6 is locked against movement by forces other than those acting to rotate clutch disc 56, since the pivots 74a and 75 of link 73 lie in line with the fixed axis of the clutch.

The deposit unit 6 remains in its outer position for use by the customer, until the motor is reenergized. An interval of a few seconds is generally sufiicient for the customer to deposit articles in the projected unit, and the teller generally will observe the transaction and depress pushbutton 73 to reenergize the motor and retract the deposit unit, when a deposit is made. The unit then returns to its inner or closed position; at which point arm 71 again opens the contacts of switches LS1 and LS2, the driving mechanism stops at its normal idle position, and the teller raises cover 15 and withdraws articles from the receptacle of the deposit unit. The teller then performs his part of the banking transaction and, after placing a deposit slip, bank book, cash withdrawal, or the lilte, in the deposit unit, he again depresses pushbutton 7i to return the deposit unit to its outer position, as described above, The customer now takes the returned articles from the unit and proceeds on his way.

If the teller is constantly alert, he may now depress pushbutton 73 so as to retract the deposit unit to its closed position and hold it there until another customer arrives. On the other hand, the teller may do nothing further at this time, but the deposit unit nevertheless will be retracted automatically to its closed position by reason of the action of the timedelay switch TS. The heating coil 11 of thisswitch becomes energized by the closing of the contacts of limit switch LS2 whenever the deposit unit moves, away frornits closed position, and this coil is constructed so as to cause a closing of the time switch contacts 8% at a predetermined interval, say fifteen seconds after the outward movement of the deposit unit. Accordingly, if the teller fails or forgets to retract the unit when a transaction is completethe action of coil 81 will soonenergize the motor id through the contacts till end the normally closed contacts 68 of limit switch LS2. It, however, the customers use of the projected deposit unit should extend beyond the interval determined by the time switch, the teller simply depresses pushbutton 79 so as to open its normally closed contacts and thus deenergizes the heating coil 81 and prevents the motor from becoming energized through its action until after pushbutton 79 is released.

It will be evident that the hinged front door id is positively moved to a vertical closed position substantially flush, with the face of wall 2 whenever the deposit unit approaches its closed position, by reason of the butting action of skirt 17 against frame 2a that forms part of wall, 2. In its. closed position, the deposit unit is fully protected against tampering or vandalism, door 14 being locked, against outward swinging movement by its butting, relation to wall 2, and the whole deposit unit being locked against forced outward movement by the blocking action; ofrthev aligned pivots. As the unit moves outwardlandinward under the teller s control, however, ob-

structions to its movement can occur, without damaging the unit or causing injury to a customers fingers or hand, by reason of the releasable connectionebetween the driving and driven discs of the clutch 46. The springs 66 determining the strength of this clutch are so tensioned that the clutch discs may slip if, for example, a customer allows his fingers to be caught between the closing front door 14 and the upper margin of opening 7 as the deposit unit approaches its closed position. Any such obstruction having been removed, the clutch elements are again brought into normal operating relation by continued operation of the driving mechanism.

In the event of a power failure, the deposit unit 6 may be rendered operable by hand so as to carry on the normal banking business, by disconnecting the linkage between the driving arm 76 and the cross bar 74, for example, by simply removing the pivot pin 75 or 74a. The sliding unit then can be moved to and fro by manipulation of handle 20.

It will be understood that the foregoing detailed deparatus without departing from the substance of the disclosure or the intended scope of the appended claims.
