## Background
CROSS REFERENCE TO RELATED APPLICATIONS
This application is a divisional of U.S. application Ser. No. 11/245,641 filed Oct. 7, 2005 now U.S. Pat. No. 7,140,810, which claims benefit pursuant to 35 U.S.C. § 119(e) of U.S. Provisional Application 60/619,480 filed Oct. 15, 2004.


TECHNICAL FIELD
This invention generally relates to pneumatic tube transaction systems and more specifically to the construction and operation of a user terminal operated in conjunction with a transaction system.
BACKGROUND ART
Pneumatic tube transfer systems may be used to carry out transactions. Such systems may be used to conduct transactions between a service provider and customers at remote locations. Such systems may be used in drive-through banking applications as well as in other transaction environments.
Pneumatic tube systems provide a fast and convenient way of handling customer transactions. In a typical pneumatic tube system, a customer station is positioned at a distant location from the service provider station in a bank or other institution. A teller or other service provider is positioned at a service provider station located within the bank. A pneumatic carrier is employed and moved through a tube by differential air pressure to send cash, checks, or other items that may be housed in the carrier between the service provider and the customer. The carrier is accessed by the customer at a remote terminal. The carrier is accessed by the service provider at a service provider terminal.
Service provider terminals are often arranged so that only a single teller or other service provider at a time may readily access a carrier at a service provider terminal. This can present drawbacks in use of the same terminal by multiple service providers. This can also limit options for configurations of service provider areas and limit efficiency. Service provider terminals may also benefit from improvements in construction and methods of operation.

Further objects of exemplary embodiments of the present invention will be made apparent in the following Best Modes For Carrying Out Invention and the appended claims.
The foregoing objects are accomplished in an exemplary embodiment by a system in which a pneumatic transfer apparatus operates to transfer a carrier through a transfer tube responsive to differential air pressure between a remote terminal located at a customer station and a user terminal located at a service provider station.
The exemplary user terminal includes a body having an opening in fluid communication with the transfer tube. In the exemplary embodiment, the user terminal includes a tubular member that is selectively movable between a closed position in which a lower end of the tubular member is adjacent a base, and an open position in which the lower end is vertically displaced from the base. A drive extending within the base operates to cause the selective movement of the movable member.
In the exemplary embodiment, the movable member is operatively connected to a flexible drive tape that is slidably engaged with a first side rail. The flexible drive tape includes apertures or slots therein for engagement with a toothed sprocket that operates responsive to the drive. In one exemplary embodiment, the first side rail has an elongated passageway therein. The flexible drive tape is adapted for slidable supported movement within the elongated passageway of the first side rail.
In the exemplary embodiment, the flexible drive tape has a length sufficient to extend alongside the movable member in a first side rail, through an arcuate channel extending in the base member, and into a second side rail disposed from the first side rail. A first portion of the flexible drive tape is operatively connected to the movable member. A second portion of the flexible drive tape moves in the base, and an extension portion includes a free distal end of the flexible drive tape which moves in the second side rail.
In the exemplary embodiment, the base of the user terminal includes two manually actuatable control mechanisms situated on opposite sides of the base. The control mechanisms enable two users situated on opposite sides of the terminal to independently operate the user terminal and control the system. The disposed side rails of the exemplary embodiment allow for access to the opening in the user terminal by users positioned on opposite sides. For example, the exemplary user terminal may be easily operated and accessed by two users arranged in side-by-side relationship at a service provider station with the user terminal situated between them.
In the exemplary embodiment, the base includes inclined faces with the control mechanisms accessible thereon to facilitate user operation. The exemplary embodiment of the user terminal also includes a resilient arrival pad and has ergonomic properties that facilitate pneumatic carrier placement and removal.
In an exemplary embodiment, a carrier is moved from a tube into an opening in the body of the user terminal via pneumatic pressure forces acting on the carrier. A user operates a control mechanism to cause the drive sprocket located in the base to rotate about its axis. Successive radially-extending teeth of the drive sprocket engage successive apertures in a flexible drive tape and move the tape member. The flexible drive tape is operatively connected to the movable member and is guided and supported in a side rail. The drive sprocket rotates in a first direction to vertically dispose the lower end of the movable member away from the base. As the movable member is vertically displaced, at least a portion of a stationary upper member telescopes into the interior of the movable member. When the movable member is disposed away from the base and moves to an open position, the carrier is accessible to the user through the opening created by the upward movement of the moveable member. The carrier can then be removed from its position in supporting connection with the base. The service provider may then remove items from and/or add items to the carrier for purposes of carrying out a transaction.
In order to send the carrier from the user terminal to a remote terminal, a user positions the carrier within the opening in the user terminal. The carrier engages the stationary upper member such that a fluid seal is formed between the carrier and an annular seal thereon and an inner wall of the upper member. The carrier is then pneumatically transported to the remote terminal through a tube by differential air pressure produced via operation of at least one blower.
Before the carrier is again moved from the customer terminal to the user terminal the system operates responsive to user input to at least one control mechanism to cause the drive to rotate the drive sprocket in the opposite direction to that when the movable member is being opened. The drive tape member moves in response to the drive sprocket and thereby causes the lower end of the movable member to be vertically moved toward the base. A resilient arrival pad on the base and a sealing surface on the movable member cooperate to form a generally airtight seal between the stationary member, movable member and the base. The carrier is then moved to adjacent the user terminal through operation of at least one blower. The carrier falls into the interior of the user terminal with its descent being slowed by the generally airtight seal creating a generally cushioning column of air below the carrier.

BEST MODES FOR CARRYING OUT INVENTION
With reference to FIG. 1, there is shown an exemplary service provider user terminal 10 that is adapted to send and receive a carrier that is movable in response to air pressure through a transport tube as will be discussed in further detail below.
User terminal 10 includes a body 12 having an opening 14 therein through which a carrier may be sent and received. User terminal 10 includes a movable member 16 and a stationary upper member 18. In an exemplary embodiment both the movable member and stationary member are generally cylindrical. In other embodiments other configurations may be used.
In one exemplary embodiment, body 12 has in fixed supporting connection therewith first and second side rails 20, 22 extending vertically in disposed relation from a base 24. A cap member 28 is positioned adjacent first and second side rails 20, 22 at a position vertically disposed from base member 24.
Movable member 16 is operative to selectively move in a vertical direction toward and away from base member 24. The closed position of movable member 16 is defined as when movable member 16 is in its lowermost position, as illustrated in FIG. 1. The open position of movable member 16 is defined as when movable member 16 is in its uppermost position, as illustrated in FIG. 2. In the exemplary embodiment, the opening 14 in body 12, and any carrier 29 (shown in phantom) held therein, is not accessible by a user when the movable member 16 is in the closed position.
In an exemplary embodiment, base 24 includes a manually actuatable control mechanism 34 operable to control movement of movable member 16 between the closed and open positions. Control mechanism 34 is further operable to cause a carrier 29 to be sent from or received at user terminal 10. In an exemplary embodiment, user terminal 10 includes two control mechanisms 34, 34′ situated in recessed areas on opposing sides of base 24.
Base 24 of the exemplary embodiment is dimensioned for ergonomic ease of use by one or two adjacent users. For example, a face 35 of the base member 24 is inclined and angled upward so that the control mechanism 34 may be easily manually accessed. An opposite face 35′ is similarly inclined so that an additional control mechanism 34′ may be easily accessed and operated.
With particular reference to FIG. 2, exemplary base 24 further includes a resilient member or arrival pad 36 operable to partially cushion the landing of a carrier as it traverses through the opening 14 of body 12. In an exemplary embodiment, the arrival pad includes a raised area to provide a resilient force absorbing portion that protects the carrier and its contents from excessive impact force upon arrival at the user terminal. Arrival pad 36 is further operable to cooperate with a sealing surface 37 on a lower end of movable member 16 to create a generally airtight seal when the movable member 16 is in the closed position. The seal helps to provide a generally controlled release of air from the terminal ahead of a carrier at the user terminal. This controlled air release cushions and limits the speed of a carrier as it arrives in the user terminal.
As illustrated in FIG. 2, in this exemplary embodiment, movable member 16 is movable relative to side rails 20, 22. Upper member 18 (not shown in this view) and movable member 16 are dimensioned so that in the exemplary embodiment at least a portion of upper member 18 telescopes with and moves in overlapping relation with the movable member 16 as movable member 16 moves from the closed position to the open position. In the exemplary embodiment, movable member 16 and at least the telescoping portion of upper member 18 are circular in cross-section, although other configurations may be used in other embodiments. In the exemplary embodiment, at least one movable member 16 is formed of transparent or translucent material in order to allow a user to view a carrier that is positioned within the user terminal 10 when movable member 16 is in the closed position.
As shown in FIGS. 3 and 4, in an exemplary embodiment, cap member 28 includes bracket 38 for holding upper member 18 and first and second side rails 20, 22 in operative alignment.
As best shown in FIGS. 3-6, base 24 includes a guide block 40 having an arcuate or U-shaped channel 42 therein. Channel 42 includes an open expanded region 50 including a drive slot 52.
In this exemplary embodiment, base 24 has extending therein a rotatable drive sprocket 44, in operative connection with a drive. The exemplary drive comprises a reversible electric motor or other suitable device for selectively rotating the drive sprocket. As best seen in FIG. 6, drive sprocket 44 includes a plurality of radially-extending projections or teeth 46. Drive sprocket 44 is situated in base 24 so that as it rotates about its axis successive teeth 46 enter expanded region 50 of channel 42. Drive slot 52 provides sufficient clearance for teeth 46 as drive sprocket 44 rotates. In the exemplary embodiment, drive sprocket 44 is operative to rotate responsive to one or more manual user inputs to control mechanisms 34, 34′. Control mechanisms 34 and 34′ may include switches or other controls which are in operative connection with suitable control circuitry 53 to cause selective rotation of the sprocket. The control circuitry may include in some embodiments suitable processor based circuitry and in other embodiments may include relay logic. Various approaches may be used.
The exemplary flexible drive tape member 54 comprises an elongated body 55 having a plurality of engageable apertures which are alternatively referred to herein as slots 56 therein. Slots 56 are dimensioned to receive teeth 46 of drive sprocket 44. Drive tape member 54 is operably associated with drive sprocket 44 so that as drive sprocket 44 is rotated, successive teeth 46 are engaged in successive slots 56 to cause movement of drive tape member 54 and controlled movement of moveable member 16, as will be explained in further detail below.
With reference to FIG. 7, in the exemplary embodiment drive tape member 54 is in operative connection with movable member 16. Drive tape member 54 includes a first portion 60, a second portion 64, and an extension portion 66. First portion 60 includes that portion of drive tape member 54 extending along the length of moveable member 16. Second portion 64 includes that portion of drive tape member 54 that moves into and out of guide block 40 responsive to movement of the drive mechanism and drive sprocket 44. Extension portion 66 includes a free distal end 70 of drive tape member 54.
With reference to FIG. 8, in the exemplary embodiment, a guide tape member portion 72 is operably connected to movable member 16 at a position opposed to the position of drive tape member 54. Guide tape member portion 72 may be similar in construction to drive tape member 54. However, the guide tape member portion operates to guide movement of movable member 16, not drive its movement. In an exemplary embodiment, guide tape member portion 72 is slidably operatively connected in supporting connection with second side rail 22.
With particular reference to FIGS. 3 and 7, in the exemplary embodiment, drive tape member 54 is operatively attached to movable member 16 via one or more fasteners 76. In an exemplary embodiment, two sets of oppositely situated fasteners 76 are utilized. In the exemplary embodiment, a mounting member 80 is mounted adjacent the movable member 16 and is generally situated between movable member 16 and a first portion 60 of flexible drive tape member 54.
With reference to FIG. 9, in the exemplary embodiment, first and second side rails 20, 22 are substantially identical in construction, although other configurations may be used. In the exemplary embodiment, the side rails have the cross-sectional configurations as illustrated in FIG. 10. The first side rail includes an elongated passageway 82 having a widened portion 84 dimensioned to receive drive tape member 54 in slidable supporting engagement therein. In the exemplary embodiment, the passageway 82 includes a narrowed slot portion 86 opening though an inward-facing wall 90 of first side rail 20. First side rail 20 further includes an elongated passage 92 therein which may be adapted to house wiring and/or other components (not shown). Second side rail 20 may include a similar elongated passage 92′. Narrowed slot portion 86 of side rail 20 is adapted to accommodate movement of fasteners 76 therein as drive tape member 54 slides relative to side rail 20. In the exemplary embodiment the side rails are each of unitary construction, and are formed through an extrusion process.
In the exemplary embodiment, second side rail 22 includes an elongated passageway 82′ dimensioned to receive guide tape member 72 in slidable engagement therein. Second side rail 22 further includes an elongated channel 94 therein which is dimensioned to receive extension portion 66 including distal end 70 of drive tape member 54 in slidable supporting engagement therein.
With reference to FIGS. 3, 9, and 10, when first side rail 20 is situated in operative engagement with base 24, passageway 82 is in operative aligned communication with channel 42. Drive tape member 54 is thus movable within first side rail 20 and within channel 42. When second side rail 22 is situated in engagement with base member 24, elongated channel 94 is in operative aligned relation with channel 42. Thus, drive tape member 54 is further movable within elongated channel 94. Drive tape member 54 extends in length beyond the lower end of movable member 16 and into channel 42 for operative engagement with drive sprocket 44. The distal end 70 of the drive tape member 54 is free to move within elongated channel 94. Guide tape member 54 is operably slidably engaged in passageway 82′.
With reference to FIG. 11, in an exemplary embodiment, user terminal 10 is operable as part of a transaction system, shown generally at 100. The transaction system 100 includes a service provider station, shown generally at 102, and a customer station, shown generally at 104. In an exemplary embodiment, the service provider station is positioned within a transaction facility such as a bank, casino, pharmacy or store. Transaction system 100 is of an exemplary configuration. Other configurations of transaction systems and components thereof are shown in U.S. Pat. Nos. 6,672,808; 6,146,057; 5,735,644; and 5,299,891 and application Ser. No. 08/889,033 filed Jul. 7, 1997 the disclosures of each of which are incorporated herein by reference.
Exemplary user terminal 10 is operatively connected to remote terminal 106 by a pneumatic tube transfer conduit 108. The pneumatic tube transfer conduit 108 includes a first generally vertically extending leg portion 110 which is adjacent to and in communication with the user terminal 10. The second generally vertically extending leg portion 112 is adjacent to and in communication with the remote terminal 104. A transversely extending portion 116 extends generally horizontally between the first and second leg portions 110, 112. The transverse portion 116 is connected to the vertically extending leg portions through radiused bends in the conduit which are radiused to enable the passage of a pneumatic carrier therethrough between user terminal 10 and remote terminal 106. Remote terminal 106 may be similar in construction to those customer terminals of the incorporated disclosures. In some embodiments the customer terminal may be similar to the user terminal disclosed herein. Remote terminal 106 is operable to allow a customer to access a carrier and exchange items with a service provided at the user terminal.
In an exemplary embodiment a first blower 120 is fluidly connected to transfer conduit 108 (which is alternatively referred to herein as a transport tube) generally in the area above the remote terminal 106. Blower 120 may be selectively operated responsive to suitable electrical control circuitry in operative connection with the control mechanisms on one or both terminals to draw negative pressure in the transfer conduit in the area generally above the remote terminal. Blower 120 further includes suitable valving so that when the blower 120 is not operated, air is generally prevented from entering the transfer conduit 108 through the blower 120. A blower 122 similar to blower 120 is connected to the transfer conduit in the area generally above user terminal 10. Blower 122 may be selectively operated responsive to suitable control circuitry in operative connection with the control mechanisms on one or both terminals to selectively produce negative pressure in the transfer conduit above the user terminal 10. Like blower 120, when blower 122 is not operating, air is generally prevented from entering the transfer conduit through the blower.
In an exemplary embodiment, a carrier 29 of the type shown in FIG. 12 or alternatively of types shown in the incorporated disclosures is enabled to be selectively moved between user terminal 10 and remote terminal 106 by the application of differential pressure produced in the transfer conduit tube by blowers 120, 122. As shown in FIG. 12, an exemplary carrier 29 includes a housing 130. The housing includes a first end member 134 and a second end member 136. The first end member 134 includes an annular resilient seal ring 140 supported thereon. Likewise, second end member 136 has an annular resilient seal ring 142 supported thereon. The seal rings provide slidable and generally fluid tight engagement between the carrier housing and an interior wall of the stationary upper member 18 and the pneumatic tube as schematically indicated 144 in FIG. 12. The angular seal rings enable the carrier to be moved in the tube through the application of a pressure differential on opposite sides of the carrier.
With reference to FIG. 13, in the exemplary embodiment, service provider station 102 enables two users to access and operate user terminal 10. Base member 24 includes dual control mechanisms 34, 34′. The construction of user terminal 10 permits access to the interior of user terminal 10 from two directions as indicated by arrows 150, 152.
In an exemplary embodiment, the user terminal 10 is readily accessible by two users who are positioned on opposed sides of the terminal. The body is situated so that each of the opposite faces of the base member and their associated control mechanisms is directed respectively to one of two users.
With the movable member in a closed position, the exemplary user terminal 10 is operable to receive a carrier 29 therein via the pneumatic terminal. When a carrier is in the terminal, as can be observed through the clear movable member 16, a first user may operate the control mechanism 34 to cause the drive sprocket 44 to rotate and thereby move the drive tape member 54. Successive slots 56 in the drive tape member are engaged by the radially-extending teeth 46 to slidably move the drive tape member through the generally 180 degree turn of guide block 40 and in the elongated passageway 82 of the first side rail 20. The first portion 60 of drive tape member is operably secured to movable member 16. Movement of the drive tape member in the first side rail causes coordinated movement of movable member 16. The lower end of the movable member is thus vertically displaced away from the base member 24 as the movable member moves from the closed position to the open position in response to the drive moving drive sprocket 44. As the movable member is vertically displaced, at least a portion of the stationary upper member 18 telescopes into the movable member 16. With the movable member in the open position so as to provide a user accessible opening, the carrier in the exemplary embodiment can be removed from between the side rails of the terminal. The contents of the carrier can then be removed, content inserted, data output therefrom or other action taken by the service provider as appropriate for the particular transaction.
When the user is ready to send the carrier 29 or a different carrier to a user at the other terminal, the carrier is placed by a user on the arrival pad 36, between the side rails. In this position the annular resilient seal ring on the upper portion of the carrier engages the inner wall of the stationary member in slidable but generally fluid tight relation. The control mechanism 34 is actuated, which causes operation of a blower by control circuitry and causes the carrier to be moved away from the terminal, through the tube to the opposite terminal via air pressure.
In an exemplary embodiment, when the carrier is to be returned to the user terminal 10 from the opposite terminal, a control mechanism is activated either at the user terminal or the opposite terminal. Drive sprocket 44 then rotates responsive to activation of the control mechanism to move the drive tape member 54 in an opposite direction. The drive tape member slides in the first side rail and in the guide block to vertically move the lower end movable member toward the base member 24, closing the opening at the user terminal. When the lower end of the movable member reaches the closed position the arrival pad cooperates with the movable member to form a generally airtight seal. As the movable member moves into the closed position, an extension portion 66 of the drive tape member slidably moves within elongated channel 94 of second side rail 22. A blower is then operated by the control circuitry to cause the carrier to move in the tube to the area in the tube above the terminal 10. The carrier then descends into the terminal cushioned by the controlled release of air from the terminal. Once the carrier has arrived in the user terminal the control mechanism can be activated to move the movable member to the open position provide a user with access to the carrier.
A second user may access and operate the exemplary user terminal 10 in similar fashion using the oppositely located control mechanism. This enables another user to conduct transactions with a user at the terminal. This makes it easier for service providers to service customers and speeds transactions.
FIG. 14 shows an alternate exemplary embodiment of a user terminal 10′. In this alternative embodiment the movable member 16′ is movable through operation of a different form of linear movement mechanism. As illustrated, an exemplary linear movement mechanism includes a rodless cylinder 160 comprising an elongated cylinder body 162, a piston 164 reciprocally moveable within the cylinder body and a carriage 168 coupled to piston 164. Movable member 16′ is secured to carriage 168 and is movable therewith in response to movement of piston 164. In this alternative exemplary embodiment a suitable source of compressed air or other working fluid is provided for selectively moving the piston of the cylinder. Control mechanisms and/or control circuitry on the base are in operative connection with suitable valves for selectively applying fluid pressure and moving the piston, and consequently the movable member, selectively between the open and closed positions.
In this exemplary embodiment the linear movement mechanism provides a single support structure extending adjacent the movable member. This enables users positioned on opposed sides of the terminal to view and access the terminal for purposes of receiving and sending a carrier. As in the case of the prior described exemplary embodiment, suitable multiple control mechanisms may be provided on the base of the unit or elsewhere to facilitate control of the terminal and the transport of carriers responsive to manual inputs.
In alternative exemplary embodiments, other types of drive members may be used for relatively moving the movable member and stationary member. Such moving devices may include for example, feed screws, rack and pinion gear arrangements and other types of drives and configurations.
Thus the exemplary apparatus and system achieve one or more of the above stated objectives, eliminate the difficulties encountered in the use of prior devices and systems, solve problems and attain one or more of the desirable results described herein.
