POINT H H REF POINT D REF ZOINT v////// 7| J REF POINT CARTRIDGE CARD TRAY BACKGROUND OF THE INVENTION This invention relates to the handling of information bearing cards. and in particular it relates to a cartridge card tray for holding a batch of information cards both in storage and on line in a card sorting apparatus.  
  It is known to code information onto a card by notching an edge of the card. preferably the bottom edge. wherein a given arrangement of notches on the bottom of the card represents a certain item of information. Such bottom edge notch cards are sorted by cooperation of the notches with code bars positioned beneath the cards. One apparatus for sorting bottom edge notch cards is shown and described in my US. Pat. No. 3.586.166. issued June 22. 1971. the subject matter of which patent is incorporated reference herein.  
  In this type of apparatus. the cards are arranged in random within a given batch. During a given sorting procedure. certain code bars are raised relative to the other code bars. and the cards within the hatch having notches matching the selected code bars drop downwardly relative to the remaining cards of the pack and these selected cards are subsequently separated from the remaining cards.  
  While the cards in a batch are arranged in random. the cards within a given batch are normally kept together. There would normally be many more batches than could possibly lit into the card sorting apparatus at any given time. This presents no problem with respect to the overall capacity of the apparatus since the batches would probably be used separately. For example a sales force may have a different batch of cards for each geographic sales region and it might be appropriate to analyze only one batch at any given time. In view of the fact that in a given operation there will be far more cards than can fit into the card sorting apparatus at any given time. it becomes necessary to store the batches not in use away from the apparatus itself. For this purpose it has been appreciated for some time that it would be suitable to provide a tray capable of holding a batch of cards both in storage and on line in a card sorting apparatus so that the tray can simply be taken off of the shell and inserted into the card sorting apparatus. However, there have been a number of problems associated with previously known card sorting trays.  
  Firstly. it is necessary or at least highly desirable to provide a handle for carrying the tray. However. with a poorly designed structure. the handle can hinder the smooth movement of the tray into the card sorting apparatus. Another disadvantage of such trays is that while the trays may be subjected to abuse while off of the machine. they must be highly precise and consistent when located in the apparatus. Another disadvantage which is again related to the need for precision when the trays are located within the apparatus is that a certain amount ol&#34;play must be provided in the vertical direction if the tray is to be inserted at all into the apparatus. However. once in place the tray must be secured quite firmly if the card sorting procedure is to be carried out properly. Still another disadvantage of known trays is that either the cards would fall out the front end or a cumbersome means would have to be provided for closing off the front end of the tray.  
  A typical tray which includes some of the above described disadvantages is shown in US. Pat. No. 2.861.706.  
  Thus. there exists a need for a new and improved tray for carrying information cards which will overcome the above disadvantages.  
 SUMMARY OF THE INVENTION Thus. it is a purpose of the present invention to provide a new and improved tray for carrying information cards both in storage and on line in a card sorting apparatus. which tray overcomes the disadvantages of pre viously known trays.  
  This purpose of the present invention is achieved by providing a cartridge&#34; card tray having a number of unique features which overcome the disadvantages of previous card trays. The term cartridge is used since the tray of the present invention is of the type which can be taken from storage and inserted or pluggeddirectly into the apparatus. The cartridge card tray of the present invention comprises a bottom support surface. side supporting means such as walls or the like and a means for limiting rearward movement of the cards into the tray. The tray includes an operating means such as a lever preferably mounted on the tray for movement within a plane. this lever carrying a card locking bar towards its front end. The lever is movable between at least an open position wherein the front of the tray is completely open for inserting and removing cards and a locking position wherein the card lock bar extends across in front of all of the cards in the tray. thus preventing removal thereof.  
  In a preferred embodiment of the invention. the tray further includes a handle movable between a raised operative position and a retracted inoperative position. In a preferred arrangement. this handle is held in its inoperative position when the lever moves to its open position.  
  In accordance with another feature of the invention. a means is provided for changing the vertical positioning of the tray after it is in the card sorting apparatus. This feature. which includes a lift bar capable of limited vertical movement and engaged by the lever provides the construction wherein the tray can be easily inserted with sufficient vertical clearance and then moved vertically thus becoming braced in place such that horizontal movement of the tray is prevented thereafter. Consequently. the tray will be firmly secured in place during normal operation of the card sorting apparatus.  
  Thus, it is an object of this invention to provide a new and improved card tray for storing information cards.  
  It is another object of this invention to provide a card tray for holding information cards which includes a means for blocking the cards to prevent removal thereof from the tray.  
  It is still another object of this invention to provide a card tray having an operating means for blocking or opening the front end of the tray and a handle for holding the tray and wherein the operating means is effective to hold the handle in its inoperative position when the operating means opens the front end of the tray.  
  It is still another object of this invention to provide a cartridge card tray which can be easily inserted into a card sorting apparatus but which can then be braced against horizontal movement after it is in place in the apparatus.  
  It is still another object of this invention to provide a cartridge card tray having an operating lever movable in a vertical plane and including a card locking bar fixed thereto such that the card locking bar either opens or blocks the front end olthe tray and further including a control surface which cooperates with a lift bar for vertically positioning the tray in a card sorting apparatus so as to prevent horizontal movement of the card tray in the forwardrear direction in the card sorting apparatus.  
  Other object and the advantages of the present invention will become apparent from the detailed description to follow, together with the accompanying drawings.  
 BRIEF DESCRIPTION OF THE DRAWINGS There follows a detailed description of a preferred embodiment of the invention to be read together with the accompanying drawings wherein:  
  FIG. I is a prospective view of a cartridge card tray according to the present invention.  
  FIG. 2 is a rear elevational view of the card tray of FIG. I.  
  FIG. 3 is a cross-sectional view taken in the plane of line 3-3 of FIG. 1.  
  FIG. 4 is a cross-sectional view similar to FIG. 3 but further illustrating an information card and portions of a card sorting apparatus so as to illustrate the relationship of the tray to the card sorting apparatus.  
  FIG. 5 is a cross-sectional view similar to FIG. 4 but illustrating another position of the tray.  
 DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now to the drawings, like numerals are represented by like elements throughout the several views.  
  Referring to FIGS. 1 thorugh 3. the cartridge card tray I0 comprises side walls II and 12 and a bottom support surface comprising a front platform 13 and a rear platform 20. The rear platform 20 is L shaped in cross-section as is evident from FIG. 1 and it extends completely across the rear of the tray except for the cut out 20a in the center thereof. A top tie plate 14 extends across the top of the tray and is connected to the side walls 11 and [2. This plate 14 includes a pair of cut outs 15 and I7 for receiving a handle 31. As is evident in FIG. 2. the ends of this handle. after passing through the respective slots 15 and 17. turn outwardly and are held in place by the vertical partitions to be explained in detail below. These outwardly turned portions form the pivot axis for the handle 31 as it pivots between the retracted inoperative position as shown in solid lines in the figures and the raised operative position as shown in dotted lines in the figures. The top plate [4 also includes a central cut out 16, the purpose of which will be explained below.  
  To achieve maximum efficiency in separating the selected cards from the remaining cards. it is preferable that all of the cards be maintained in an upright position. For this purpose, there are provided a number of vertical partitions 21, 22, 23, 24, 25, 26, 27 and 28 between the side walls 11 and 12. To further assist in keeping the cards vertical. a light spring 30 is provided in each space between adjacent partitions, said spring 30 being mounted on one of the walls forming a bay between adjacent partitions and sprung lightly outwardly toward the other wall. As cards are placed into any given hay. the cards will push the spring 30 back. but the spring 30 will retain the cards in an upright position.  
  The card tray of the present invention can be constructed in any size. However. it has been found most appropriate to construct the tray so that it holds 500 cards of a size generally referred to as IBM&#34; cards. The overall unit should be of a size capable of being stored in a standard data card file drawer.  
  The space between partitions 24 and 25 includes the operating means provided for opening or blocking the front of the tray and also for securely positioning the tray in place after it has been inserted into the card sorting apparatus. Referring now to FIG. 3. this operating means includes an operating lever having a card lock bar 32 extending across the front thereof (see also FIG. I). A fixed locking pin 41 and a fixed pivot pin 42 extend across the space and are fixed to one or both of the plates 24 and 25. The operating lever 40 includes a grip portion 60 having a guide surface 61 which terminates rearwardly in a vertical surface which terminates at locking recess 62. The lever further includes a handle locking pin 63, the purpose of which will be explained below. The lever further includes a pivot pin slot 64 which receives the pivot pin 42. The lever 40 is urged rearwardly by means of a spring 44 which is anchored at end 43 to the lever 40 and at its other end to a pin 45 rigid with the plates 24 and/or 25. The operating means further includes a lift bar having a pair of cars 50a which have passing therethrough adjustment pins 51 and 52. These pins 51 and 52 are threaded and passed through threaded openings in the ears 50a so that the vertical positions of these pins can be adjusted. This lift bar 50 is capable of limited vertical movement, bounded at the upper limit by engagement of the tops of cars 50a with upper abutment pins 53 and and downward movement is limited by engagement of the pins SI and 52 with lower abutment pins 54 and 56. The pins 53. 54, 55 and 56 are fixed with respect to the plate 24 and/or plate 25. The top of lift bar 50 includes a straight surface 57 and a recess 58. The lever 40 includes a lift bar control surface which cooperates with the top of the lift bar 50.  
  The operation of the invention will be described with respect to FIGS. 4 and 5. However, before explaining the operation, the additional elements of FIGS. 4 and 5 which correspond to elements of the card sorting apparatus will be described. Incidentally, while these elements of the apparatus will move during the card sorting procedure, they may be considered as fixed for the present discussion since they are indeed fixed during the time that the tray is inserted and removed. Referring now to FIG. 4, the apparatus includes front and rear rest members 71 and 72 and a cam which extends up between the plates 24 and 25. There is also included a front riser bar 74 and the usual code bars 73.  
  Referring to FIGS. 4 and 5. the present invention operates as follows. Referring first to FIG. 5, this figure illustrates the tray with the operating lever 40 with the bar 32 blocking the front of the cards to prevent removal of the cards from the tray. At this time the pin 63 is out of the way of the handle 31 so that the handle can be pivoted upwardly for normal use. In this position the lever 40 is pulled forwardly until the slot 64 is in its forwardmost position with the pin 42 at the rear end of the slot. At this time also the pin 41 is received securely in the locking recess 62. In this position also the lift bar control surface 65 engages the flat top 57 of the lift bar and urges the lift bar downwardly so that the pins 5] and 52 engage lower abutment pins 54 and 56. In this position the tray can be inserted into the machine. As indicated above. elements 71, 70 and 72 are fixed. The tray is then inserted from the left&#39;hand side with the partitions 24 and 25 straddling the cam 70. Because of the cut out a the tray can indeed slip over the cam 70 from left to right until it reaches the position as shown in FIG. 5. lnsertion has been made easier by the fact that the tray is constructed so as to pass-over the cam 70. Note in FIG. 5 the fact that the platforms l3 and 20 are spaced above their respective rest members 71 and 72 and the top of cut out 20a is spaced by a height Z above the upper rear corner ofcam 70. However. this looseness which has made insertion easier must be removed so that the tray will be firmly secured in place for an effective card sorting procedure. First of all the handle 3] has been lowered to the retracted position even before tray was inserted into the apparatus. The operator then grips the portion 60 of lever 40 and lifts the same upwardly and pushes it back until the position of FIG. 4 is achieved. This movement accom plishes several results. Firstly. the card lock bar 32 is raised up and over the information cards. Next. the handle locking pin 63 moves over the handle 31, securing the same in place. Finally. the lift bar control surface 65 has now moved upwardly because of the fact that height X is less than the height Y. and as a result thereof the entire tray drops relative to the lift bar 50 until the platforms l3 and 20 rest on their respective rest members 7] and 72. This locates the tray vertically. in addition. the tray is secured against horizontal movement at reference point B by the engagement of the front platform 13 with the front end of the cam 70 and at reference point C by the engagement of the upper part of platform 20 above the slot 20a with the rear of cam 20.  
  The card tray is now secured in position and the card sorting apparatus may now be operated to select certain cards in the manner as explained in our said earlier patent.  
  Although the invention has been described in considerable detail with respect to a preferred embodiment thereof, it will be apparent that the invention is capable of numerous modifications and variations apparent to those skilled in the art without departing from the spirit and scope of the invention.
