Description

(54) REMOTE ENVELOPE DEPOSITORY CONSTRUCTION (71) We, DIEBOLD, INCORPO RATED, a corporation organized and exsiting under the laws of Ohio, of 818 Mulberry Road, S.E. Canton, Stark County, State of Ohio 44702, United States of America. (Assignees of ROBERT JOHN BECK, HERBERT MORELLO and JACK MARK RICHARDSON), do hereby declare the invention, for which we pray that a patent may be granted to us, and the method by which it is to be performed, to be particularly described in and by the following statement:- The present invention relates to equipment for accepting bank deposits from a customer at unmanned stations remote from a bank's central office. Such equipment accepts deposits automatically from authorized persons.The depository equipment desirably may be combined with automatic currency dispensing equipment so that various banking services may be conducted at such remote unmanned stations continuously, day in and day out, twenty-four hours a day.

The depository equipment issues a receipt to the customer-depositor after the deposited material has been discharged to a deposit chest. Operation of the depository equipment may be co-ordinated with or actuated by devices also used in controlling currency dispensing operations at the remote station.

Many different types of bank depository mechanisms at unmanned stations are known in the prior art, both hand and power driven, and straight line and rotary in design. Depository devices which accept only deposit-containing envelopes have used straight line conveyors, either hand or power driven; and frequently belt-type conveyors are used, such as shown for example in U.S. Patent Nos. 2,963,333, 3,028,074, 3,078,789, and British Patent No.

1,466,356.

Envelope depository devices also have been used as components of automatic banking equipment which are adapted for dispensing currency, as shown in British Patent No. 1,466,356 and U.S. Patent No.

3,897,901. Depository components of automatic banking equipment also have been of the rotary type as in said U.S. Patent No. 3,897,901.

It is necessary at automatic unmanned banking equipment installations to provide the customer-depositor with a receipt for the deposit-containing envelope, and to identify the envelope and receipt with the same indicia. Prior depository constructions which issue receipts, either have severed a tag from special deposited-material containers, or have printed the depositidentifying indicia on envelope and receipt simultaneously during conveyor travel.

Prior depository mechanisms using straight-through belt or chain conveyors have had conveyor means longitudinally split centrally to accommodate printer means actuated during conveyor travel, or to accommodate deposit entry sensor triggers. Some of these conveyor mechanisms have required paddles mounted on the conveyors to push or retain in a pocket the deposit-containing envelope during movement along the conveyor.

Also, some of the prior conveyor-type depository mechanisms have had entry slots that are always open which renders the depository mechanism vulnerable to possible "fishing" attack.

The various types of prior depositories discussed above also entail the use of complex operating and security components and mechanisms.

Finally, the requirement of providing special tags and tag-severing mechanism for containers for the deposits, and of maintaining availability of such special deposit containers, as distinguished from simple envelopes, at unmanned stations is not economically practical.

There thus exists a need in the field of bank depository services for a depository mechanism for umanned stations which provides maximum security for the deposited material, which issues a receipt for the deposit after the material has been discharged to a chest. which utilizes only simple envelopes for containing the material to be deposited such as bank notes, checks and coin, which includes a belt conveyor having a simple design, construction and operation eliminating central longitudinal spacing or separation of conveyor components. and which provides effective gate valve means at the entry and exit ends of the conveyor for maintaining maximum security.

Embodiments of the present invention seek to provide:-- new remote depository equipment to be actuated by a customer to open a positively-locked gate valve closing an entry slot for the depository mechanism; such a construction equipped with a simple driven endless belt conveyor mechanism extending from the entry slot to an exit end and discharging into a security chest; such a construction with printer means exteriorly of the conveyor having components located beyond the exit end of the conveyor to print indicia on a deposit-containing envelope being discharged from the conveyor simultaneously with the printing of similar indicia upon a receipt form issued to the customer after the envelope has been discharged to a security chest; the described components in a form having a simple design, construction and minimum cost of manufacture, installation and maintenance; and a construction difficult to damage by an intruder and which maintains maximum security at all times for the deposited material.

In general terms the present invention provides an envelope depository construction of a type in which an envelope is inserted through an entry slot of the construction and is transported from the entry slot by belt conveyor means from a conveyor entry end to a conveyor exit end and deposited in a safe-like chest; wherein the belt conveyor means comprises two endless, laterally continuous, opposed belt conveyors to transfer an envelope by trapping the envelope in the bite between the opposed conveyors, and conveyor drive means for driving the belt conveyors; and there are provided entry channel means at the conveyor entry end; exit channel means at the conveyor exit end; slidable entry and exit gate plate means located respectively at the entry and exit ends of the conveyor means; means for slidably mounting the entry and exit gate plate means for movement between open and closed positions with the entry gate closed when the exit gate is open and vice versa; means for moving the entry and exit gate plate means between such positions, and for locking the entry gate plate in closed position; and means for actuating the conveyor drive means and the plate moving means to move the entry gate plate means for normally closed position to open position for accepting a deposited envelope.

Similar numerals refer to similar parts throughout the various figures of the drawings.

A remote umanned automatic banking unit equipped with the improved envelope depository mechanism is indicated generally at 1 in the drawings. The improved depository unit or mechanism is indicated generally at 2 and may be incorporated in the unit 1 to receive envelopes containing deposits entered through an entry slot 3 contained in the facia 4 of the banking unit 1.

As shown, the unit 1 may be a vault or safe-like structure 5 for security protection.

The structure 5 has various compartments 6 and 7 therein closed by safe-like doors 8 and 9, having usual combination lock means 8a and 9a. A partition 10 extends between compartments 6 and 7 and has an access opening 11 communicating between the compartments 6 and 7. The compartment 7 may be termed a chest into which deposited material is discharged from the depository mechanism 2.

Other compartments (not shown) may be formed in the vault structure 5 containing currency storage and dispensing means which may be actuated by a keyboard 12 and controlled by other devices, generally indicated at 13 in Fig. 1. The remote unit 1 may be of the general type of automatic currency dispenser shown in British Patent No. 1,496,984 having a card entry slot 14 for the insertion preferably of a personalized conventional magnetic stripe plastic coded card for initiating an automatic banking transaction, as described in said British Patent.

The devices generally indicated at 13 may include a panel display means for displaying instructions for carrying out a selected banking operation. A rotary drawer 15 also is provided for delivering cash, when a cash dispensing operation at bank unit 1 is carried out, and such rotary drawer may be of the type shown in British Patent No.

1,488,927. The unit 1 also may be equipped with a receipt slot 16 where a receipt for a transaction may be delivered to the customer at the completion of such banking transaction, whether it be one of depositing or one of cash dispensing.

The depository unit 2 which characterizes the concept of the invention is an improvement upon the remote depository of British Patent No. 1,446,356 and it retains desirable features of the prior construction but eliminates disadvantages which have been encountered with the prior construction.

Brackets 17 are mounted to extend upward from partition wall 10 to support mounting plate 18 (Figs. 5, 6 and 7). Side plates 19 and 20 for the conveyor mechanism are mounted on plates 18. A pair of tie rods 21 at the entry end 22 and another pair of tie rods 23 at the exist 24 of the depository unit 2 tie the side plates 19 and 20 together and maintain them in proper spaced relation.

A pair of spaced conveyor entry rollers 25 mounted on shafts 26 journaled in side plates 19 and 20 are located at the unit entry end 22 and a similar pair of spaced conveyor exit rollers 27 mounted on shafts 28 journalled in side plates 19 and 20, are located adjacent the exit end 24 of the unit 2. An upper flexible conveyor or transport belt 29 and a lower transport belt 30 are trained over the rollers 25 and 27.

The belts 29 and 30 preferably are formed of a soft rubber composition which will yield sufficiently to conform to the thickness of an envelope being transported through the mechanism by the belt conveyor between the belts 29 and 30.

Rollers 25 and 27 and belts 29 and 30 are driven by a motor 31 mounted on a bracket 32 extending from a gear box 33 carried at 34 by a C-shaped housing enclosure 35 (Fig.

7) that is bolted at 36 to the exterior of the side plate 20 adjacent the exit end 24 of the unit 2. The motor 31 drives gears (not shown) contained in the gear box 33, which in turn drive a shaft 37 extending from the gear box 33 to a coupling 38 connected to one end of the upper conveyor roller shaft 28 at the unit exit end 24. An upper gear 39 mounted on upper roller shaft 28 meshes with lower gear 40 on the end of lower roller shaft 28 (fig. 8) so that the belts 29 and 30 are driven in synchronism.

A pair of Z-shaped brackets 41 is mounted on the entry ends of the side plates 19 and 20 with their shoulder portions 42 spaced from the ends of side plates 19 and 20 to provide channels in which an entry gate plate member 43 is slidably mounted for movement in a plane perpendicular to the bite 44 between the transport belts 29 and 30 (Figs. 6 and 11).

Upper and lower U-shaped channels brackets 45 and 46 have their legs 47 fixed to the inner flanges 48 of the Z-shaped brackets 41. The webs of channel brackets 45 and 46 are spaced apart to form an entry channel 49 aligned with the bite 44 between transport belts 29 and 30 (Figs. 5, 6 and 11).

The outer ends of the webs of brackets 45 and 46 are flared at 50 to provide a throat opening for entry channel 49, and flared ends 50 engage gaskets 51 against the recessed walls 52 and 53 of the facia 4. The entry slot 3 is formed in the facia wall at the corner between the facia walls 52 and 53 (Figs. 5 and 6) aligned with the entry channel 49 and the bite 44 between the transport belts 29 and 30.

Another pair of Z-shaped brackets 54 is mounted on the exit ends of the side plates 19 and 20 with their shoulder portions 55 spaced from the exit ends of the side plates 19 and 20 to provide channels in which an exit gate plate member 56 is slidably mounted for movement in a plane perpendicular to the bite 44 between the transport belts 29 and 30 at the unit exit end 24 (Figs. 4 and 10).

A pair of channel brackets 57 is mounted by screws 58 in spaced relation extending between the exit ends of the side plates 19 and 20 (Figs. 5 and 10). The spacing between the brackets 57 forms an exit channel 59 aligned with the bite 44 between the transport belts 29 and 30 at the exit end of the conveyor.

The exit ends of Z-shaped brackets 54 have bifurcated flange portions comprising upper support flanges 60 and lower roll support flanges 61 (Figs. 4, 5, 10 and 17). A printer assembly 62 is mounted by screws 63 on and between the upper support flanges 60 of the Z-brackets 54.

The printer assembly 62 thus is mounted beyond the exit end 24 of the conveyor and printer 62 includes a housing 64 and a printer head 65 of usual construction, the operation of which is described below.

A printer platen roll 66 is journaled on roll support flanges 61 of Z-brackets 54 between the flanges 61 and below the printer head 65 (Figs. 8 and 17). One end of the shaft 67 of roll 66 projects to a zone adjacent the drive motor housing 35 (Fig. 4), and a pulley 68 is mounted on shaft end 67 driven by a belt 69 trained around a drive pulley 70 mounted on the lower exit roller shaft 28 (Fig. 7).

A gate valve operating lever 71 has a crank arm 72 fixed thereto intermediate the ends of lever 71, and the projecting end 7J of arm 72 is fixed to a shaft 74 (Figs. 4 and 5) which is journaled on and extends between side plates 19 and 20. One end 75 of shaft 74 projects outside of side plate 19 and is engaged by a spring 76, the other end of which is connected at 77 to the armature 78 of the solenoid 79, mounted on the outside of side plate 19 by screws 80.

A cam plate 81 is mounted on pins 82 for limited longitudinal movement in a direction parallel with the line of travel of the conveyor belts. The pins 82 extend from a spacer block 83 located on the outside of side plate 19 adjacent the solenoid 79. The pins 82 extend through elongated slots 84 in the cam plate 81 to permit the described movement.

An ear 85 extends outwardly from one end of cam plate 81 forming part of the connection 77 of spring 76 with the solenoid armature 78, the ear 85 and armature 78 being joined by cotter pin 86. A channel member arm 87 is mounted on lever 71 by screws 88 (Figs. 4, 5 and 6) projecting laterally to a zone adjacent the cam plate 81 and solenoid 79. The outer end of arm 87 has a downturned flange 89 provided with a cam pin 90 which projects into a cam slot 91 in cam plate 81.

The cam slot 91 is angular in shape, as being shown in Figs. 5 and 6, and has an elongated actuating portion 92 extending at an angle to the line of travel of the belts 29-30. At the top end of the angular cam slot portion 92, a locking slot portion 93 is provided which extends in a direction parallel with the line of travel of the belt conveyor 29-30. The camp pin 90 is in a locked position when located in cam slot locking portion 93 shown in Fig. 5 and is unlocked when in the angular actuating position 92 as shown in Fig. 6, for reasons to be described.

The entry end 94 of gate- lever 71 extends through a slot 95 in entry gate plate 43 (Figs.

6 and 11), and the exit end 96 of lever 71 extends through a slot 97 in the exit gate plate 56.

The construction and coordinated relationship between the lever 71 and gate plates 43 and 56, and the sliding movements of the plates 43 and 56 in the described channels between the ends of the side plates 19 and 20 and the Z-brackets 41 and 54, provide for see-saw movement of lever 71 about the pivot axis of shaft 74 to lower the exit gate plate 56 (Fig. 6) when the entry gate plate 43 is raised, and to lower the entry gate plate 43 (Fig. 5) when the exit gate plate 56 is raised.

When the entry gate plate 43 is in the lowered position, communication between the entry channel 49 and the belt conveyor 29-30 is cut off, as shown in Fig. 5; and when the exit gate plate 56 is lowered, communication between the exit channel 59 and the exterior of the conveyor mechanism is cut off. as shown in Fig. 6.

Thus, irrespective of the position of the gate plate lever 71, at no time is there direct communication from the exterior of the unit 2 through the facia slot 3 and the conveyor mechanism, to the interior of the protective compartments 6 and 7 of the bank unit 1.

Furthermore, when the gate plate 43 is in down or closed position of Fig. 5, cam pin 90 is in the locking portion 93 of cam slot 91 which effectively locks the lever 71 and gate plate 43 in the down, closed or cut-off position. The construction of a sliding gate plate locked, per se, in a locked or closed position provides maximum security against attempts of an intruder to dislodge such gate plate and gain access to the interior of the unit 1. This cooperative arrangement avoids difficulties that can be experienced from a security standpoint with the rocking bar construction of the depository in British Patent No. 1,446,356 wherein the slotted closure flange at the end of the rocking bar for closing the deposit entry slot can be readily pried open.

The operation of the lever 71 is controlled by the solenoid 79 and the spring 76.

Assume that the parts are in the normal position of Fig. 5 with the entry gate plate 43 closed. At such time that the solenoid 79 is energized, its armature 78 moves in the direction of the arrow 98 (Fig. 5) which pulls cam plate 81 to the right from the position of Fig. 5 to the position of Fig. 6. During this cam plate movement, cam slot 91-92-93 engaging cam pin 90 moves the cam pin downward which imparts forces that pivot the lever 71 about shaft 74 from the position of Fig. 5 to that of Fig. 6, thus raising entry gate plate 43 and lowering exit gate plate 56.

When the solenoid 79 is deenergized, spring 76 pulls solenoid armature 78 back to the position of Fig. 5 moving cam plate 81 ot the left from the position of Fig. 6 to that of Fig. 5. During such movement, cam pin 90 rides along cam slot 91 to the locked position of cam pin 90 in locking portion 93 of cam slot 91, thus moving lever 71 back to the position of Fig. 5 from that of Fig. 6, closing entry gate 43 and opening exit gate 56.

The cam plate 81 (Figs. 5 and 6) has a cam contour 99 at its bottom edge, engaged by a Pair of limit switches, LS-100 and LS101.

these limit switches, LS-100 and LS-101, are used to signal the control circuitry for the operation of the depository unit 2 as to the status or position of the cam plate 81 and therefore of the lever 71 and the gate plates 43 and 56. Thus, assuming that L 100 is open and LS-101 is closed in Pig. 5, the cam plate 81 in a position locking lever 71 and the entry gate plate 43 is closed.

The reverse status is shown in Fig. 6 where limit switch LS-100 is closed and limited switch LS-101 is open, which signals that the cam plate 81 has been released from locking position and the that lever 71 has opened entry gate plate 43.

The entry channel 49 is provided with a pair of entry photocell or sensor components 102 and 103, which project a light beam across the channel 49 to detect the status of a deposit envelope passing through the entry channel 49. Similarly, the exit channel 59 is equipped with a pair of exit photocell components 104 and 105 to signal the status of a deposit envelope passing through the exit channel 59.

Preferably, the lower entry roller shaft 26 (Figs. 4, 5 and 6) is equipped with an inductance switch comprising a blade 106 on the shaft 26 and a field 107 which initiates signals on rotation of shaft 26 to indicate that the conveyor belts 29--30 are moving.

The depository unit 2 is provided (Fig. 2) with a receipt printer 108 which may be mounted at a convenient location within compartment 6 to print a receipt containing the same information as printed by the printer 62. The operation of the printer 62 is coordinated or synchronized with that of the receipt printer 108 and printer 108 will not deliver a printed receipt through the receipt slot 16 until a depository cycle has been completed, as described below. The receipt printer 108 and envelope printer 62 may be of known types and may be operated in the manner described in British Patent No. 1,466,356.

The printer head 65 of envelope printer 62, when energized, moves up and down against the platen roll 66 to imprint an envelope passing between the printer head 65 and roll 66 with any desired identifiying indicia such as transaction number, the date and time. The same information is printed by the receipt printer 108 on the receipt which is issued.

Preferably, a typical electrical or electronic, preferably printed, circuit board 109 containing control circuitry may be mounted on the outside of side plate 20 of the conveyor mechanism. The control circuitry in which the solenoid, the sensors, the printer actuators, the conveyor drive motor, etc. are connected also preferably includes a control computer for the cycled depository operation.

Manifestly, the operation of the various components are coordinated and programmed using typical circuitry and electrical or electronic control devices automatically to operate the equipment in the manner described upon activation of the equipment.

Typical operation of the envelope depositing cycle carried out in the use of the new depository unit 2 incorporating the concepts of the invention is illustrated diagrammatically in Figs. 12 through 16. If the depository 2 is a part of a remote banking unit 1, as illustrated, which also has cash dispensing equipment, then the use of the equipment generally may have been initiated by a customer using whatever means is provided to energize the unit 1. This may include entry of an identification number in the keyboard 12, following which one of the buttons of the keyboard may be pressed to energize the depository unit 2.

However, if the depository 2 constitutes a remote deposit station by itself, it can be energized directly merely by pressing a button controlling or energizing the circuitry and supplying power to the components. Such a button may, if desired, be protected by a lock and key or may be part of a key switch which is unlocked by a key in the authorized possession of a customer.

If the depository 2 is a part of a remote automatic banking unit 1, which is actuated by a customer card having magnetic strips inserted into the card entry slot indicated at 14, the automatic operation of such a unit 1, as described in said British Patent No.

1.496,984 at a proper time in the cycle of operation will present a message at the display panel 13 directing the depositor to depress a certain button to indicate the desire to make a deposit. When the customer presses the indicated button, the depository unit 2 will be energized.

Regardless of the manner in which the unit 2 is energized, when energized, the solenoid 79 is energized and pulls the cam plate 81 from the position of Fig. 12 to the position of Fig. 13 opening entry gate plate 43 to allow an envelope B to be entered into the conveyor mechanism through entry channel 49. At the same time that the entry gate plate 43 is opened, the exit gate plate 56 is closed. At the same time, the limit switches. LS-100 and LS-101, signal the computer that the entry gate is open. At the same time, motor 31 is energized to drive the conveyor belts 29 and 30.

Preferably, if no envelope E is entered through the entry channel 49 and past the entry photocell sensors 102 and 103 within a predetermined time thereafter of a few seconds, the motor 31 is stopped, the solenoid 79 is deenergized, and the spring 76 through lever 71 closes entry gate plate 43.

However, if a deposit envelope E is inserted by a customer into the entry channel 49, it is engaged by the belt conveyor 29-30 and passes along the conveyor, as indicated in Fig. 13. As the trailing end of the envelope E passes entry sensor 102-103 after, say three to six seconds delay to'assure clear passage of å crooked or diagonally-entered envelope, a signal is given to the control circuitry and the solenoid 79 is deenergized and spring 76 returns the entry gate plate 43 to closed and locked position and the exit gate plate 56 is opened as shown in Fig. 14.

At this time, the switches, LS--100 and LS-101, are actuated by the return of the cam plate 81 to the position of Fig. 5 and a signal is given to the computer that the entry gate plate 43 has been closed and locked.

The envelope E continues to be conveyed until the leading end of the envelope E passes under the exit photocell sensors 104 and 105 (Fig. 14) which signal the printer assembly 62 and energizes the same for operation so that as the envelope E continues to travel, as shown in Fig. 15, the printer head 65 depresses several times at intervals to print indicia on the envelope.

When the trailing end of the envelope passes the exit sensors 104 and 105 (Fig. 16) the sensors 104 and 105 signal such condition, and through the control circuitry the motor 31 is stopped, and a signal is sent to the computer to issue to the customer the receipt from receipt printer 108, which has been printed at the same time that printer head 65 was actuated. Meanwhile, envelope E drops through the opening 11 into the security deposit chest 7.

The unit 2 thus has completed a cycle of operation and is ready for another similar cycle of operation, the entry gate plate 43 being closed and locked, awaiting actuation of the activating means by a customer who desires to carry out another deposit operation.

The important facets of the concept of the improved straight-through travel envelope depository include retaining all desirable features of British Patent No.

1,466,356 include the provision of a belt conveyor structure having an entry gate and entry sensors 102-103 which are located and coordinated in operation to prevent closing of the entry gate plate 43 at any time while the envelope E or a portion thereof is located beneath the gate plate 43; include a cooperative arrangment of the depository components in which the passage of the leading end of the envelope E beneath the exit sensors 104-105 activates operation of the printer 62; include a construction in which a printer is divorced from a location within the confines of the conveyor mechanism and thus avoids complicated conveying mechanism which must be split longitudinally to accommodate the printer; include a construction in which the trailing end of the envelope E which has been transported through the conveyor mechanism is sensed by the entry sensor 102-103 to activate the control system to deenergize the solenoid 79, thereby closing the entry gate plate 43; include switch means actuated by the cam plate to indicate the fully open or fully closed position of the entry gate; and include a construction wherein sliding gate plates are used for the entry and exit ends of a simplified belt conveyor system to provide for maximum security.

In describing the operation of the equipment and in summarizing important facets of the concept, the trailing end of the envelope E has been stated as being sensed by the entry sensors 102-103 to close the entry gate plate 43 and open the exit gate plate 56. Alternatively, control of the positions of the entry and exit gate plates 43 and 56 to open the exit gate plate 56 may be exercised by the exit sensors 104-105 so that when the leading edge of an envelope E arrives at the exit sensors 10S105, these sensors activate the control system to deenergize the solenoid 79 to thereby close the entry gate plate 43 and open the exit gate plate 56.

The reason for this alternatively described control of the entry and exit gate plate positions is to prevent the equipment from being fooled or improperly operated by an individual accidentally or intentionally causing a malfunction by inserting in and immediately removing the front end of an envelope from the entry channel 49 and sensor 102-103. Sensors cannot distinguish a leading from a trailing envelope end but signalling from sensors depends on blocking or unblocking a light beam.

Regardless of the manner in which the ends of an envelope actuate sensors to activate the control system to change the gate plate positions, the equipment functions otherwise in the same manner.

Accordingly, the foregoing new features of the present invention provide a new remote envelope depository construction and mode of operation which achieve the stated objectives, eliminate difficulties arising from prior devices, and solve problems and obtain the described new results.

In the foregoing description, certain terms have been used for brevity, clearness and understanding, but no unnecessary limitations are to be implied therefrom beyond the requirements of the prior art because such terms are used for descriptive purposes and are intended to be broadly construed.

Moreover, the description and illustration of the invention is by way of example, and the scope of the inveniton is not limited to the exact details shown or described.

Claims

**WARNING** start of CLMS field may overlap end of DESC **. intentionally causing a malfunction by inserting in and immediately removing the front end of an envelope from the entry channel 49 and sensor 102-103. Sensors cannot distinguish a leading from a trailing envelope end but signalling from sensors depends on blocking or unblocking a light beam. Regardless of the manner in which the ends of an envelope actuate sensors to activate the control system to change the gate plate positions, the equipment functions otherwise in the same manner. Accordingly, the foregoing new features of the present invention provide a new remote envelope depository construction and mode of operation which achieve the stated objectives, eliminate difficulties arising from prior devices, and solve problems and obtain the described new results. In the foregoing description, certain terms have been used for brevity, clearness and understanding, but no unnecessary limitations are to be implied therefrom beyond the requirements of the prior art because such terms are used for descriptive purposes and are intended to be broadly construed. Moreover, the description and illustration of the invention is by way of example, and the scope of the inveniton is not limited to the exact details shown or described. WHAT WE CLAIM IS:
