16 Claims.

The present invention relates broadly to record controlled machines and more particularly to Sorting machines for record cards bearing data usually represented by perforations. As is well known in the art to which this machine refers,

the card perforations are analyzed by an analyzing mechanism which controls the distribution of the cards into sorting receptacles. The machine is provided with a plurality of sorting blades cooperating with record controlled elements which separate said blades corresponding to the perforateddata to provide a passage for the card to conduct it to the upper proper receptacle.

It is the main object of the present invention to provide new and efiicient improvements on sorting machines of this nature.

Another important object of the invention consists in the provision of controlling elements for the distributing mechanism which are successively brought into their corresponding controlling position in accordance with the successive analysis of the index point positions.

A further object is to provide controlling elements for each sorting blade said elements being brought successively into their controlling position and further provision is made for a common record controlled element to cause controlling operation of the controlling elements which are in controlling position at the time the perforations in the record card pass the analyzing means.

Another object of the invention is to provide a controlling drum bearing diametrically arranged controlling elements, said elements being axially and angularly displaced with respect to each other.

A further object of the invention is to provide a rotary controlling mechanism adapted for successive cooperatibn with the individual sorting blades in accord with the successive analyses of the index point positions.

Another essential object of the invention consists in the provision of a common record controlled controlling device for the sorting blades and a coupling device for successively coupling each sorting blade with said controlling device in accordance with the successive analyses of the index point positions.

A further important object of the present invention consists in a new arrangement and a new shape of the sorting terminals of the sorting blades, which enable reliable sorting operation with high speed and without considerably straining the sorting blades.

Another object of the invention is to provide a new contact mechanism for record controlled machines, said contact being under the control of a hand operated element and of a record controlled element, arranged in the path of the record cards passing through the machine.

Another object of the invention relating generally to record controlled machines is to provide one common contact governing both starting and stopping of the machine.

Another object of the invention is to provide new and improved structures in connection with the cover plate for the sorting receptacles.

Other objects and advantages will be hereinafter set forth in the accompanying specification and claims and shown in the drawings which show by way of illustration what is now considered to be a preferred embodiment of the invention.

The present invention provides the usual card feed wh ch extracts perforated cards one at a time from a card magazine or stacker and feeds them to an analyzer. The analyzer searches the cards for data perforations and governs their 110 distribution to sorting pockets or receptacles according to their analyses. A plurality of sorting blades, one for each pocket, are provided and the ends of the blades are separated to form the proper passage for each card to lead it to the sorting pocket called for by the perforation which it bears. Contrary to the usual operation in which the blades are moved and some or all of them stopped to provide or present an opening for each card, the present case contemplates a plurality of normally stationary blades with their ends echeloned and a member cooperating with the end of each blade and tending when operated to move the blade and thus form the distrlbuting passage. The members which thus operate the blades may take numerous forms but for the present disclosure it may be assumed that tice, it will be understood that this is not they consist of rods. A rotary member carrying a slidable pin for each rod presents the pins successively for cooperation with the several rods. When the analyzer detects a certain perforation or group of perforations on a card, the slidable pin corresponding to the data represented is caused to operate, at the time when it is in cooperative relationship with its rod to in turn operate the latter and open the proper passage way for the card. This mechanism will be fully described hereinafter.

For the purpose of clearly explaining the invention it has been shown as applied to an electric sorter of the type in which single perforations or Hollerith cards are analyzed while in motion. To further avoid complication and this applies equally Well to practice, the machine has been constructed in such a manner that the distributing passage for each card is prepared substantially simultaneously with its analysis. That is the ends of the sorting blades are so located that immediately a perforation is encountered a corresponding blade a shifted and the leading edge of the card is in position to immediately enter the passage thus formed. While this eliminates the necessity for holding parts set for any appreciable time and is found convenient in pracan essential feature of the invention.

Card feed mechanism The cards are fed from a card stack 2 (Fig. 2) by means of the reciprocal picker 1 to the first pair of feeding rolls 3. The mechanism for moving the picker 1 comprises two symmetrically arranged plates 4 which are pivoted at their lower ends upon a block 5 mounted upon the screw element 6. Each platecoacts with a pair of pressure springs 7 connected to the plate at one end and guided by pins 8 fixed to the frame of the machine. The upper part of each plate 4 passes into a notch of picker element 1. Upon the shaft 8 which makes one revolution for each machine cycle are fixed two cam disks 9 coacting with the plates 4 so as to move these plates to and fro during each machine cycle whereby the picker 1 picks a card from stack 2 and delivers it to the transport rolls which are all driven in unison. A pawl 10 is provided on the machine frame and passes into a slot of the picker unit. This pawl is turned in clockwise direction when it is engaged by the extreme left part of the picker element on return movement of the same and therefore will engage the lower cards of the stack and align them prior to each picking operation. This picker mechanism is fully described and claimed in my copending application Serial No. 321,291,

filed November 23, 1928, and is not per se part of the present invention.

As the general operation of the card feed mechanism will be understood from the above explanation it is not necessary to go more into detail.

Distributing mechanism In the present machine sorting blades of a new shape are used as may be seen in Figs. 9 and 10. The individual sorting blades 11 lie upon each other at their forward ends in the usual manner. With the exception of the upper blade, each is cut away at its end to form a narrow finger 126 having. an angular extenson 127 which extends slightly beyond the longitudinal middle line of the blade. The fingers 126 are formed on opposite sides of alternate blades and the extensions 12'? rest upon each other, as may be seen in Fig. 10, but leave a clear portion underneath to cooperate with operating rods 13 (see Fig. 9). The uppermost blade is tapered at its end and rests upon extension 127 of the blade directly below it. Obviously, however, this uppermost blade may also be formed similarly to the others if desired. The tip 128 of each extension 127 is provided with a struck up tongue 12 inclined in the direction of card feed to lift the card slightly and raise it to the level of the next blade as it feeds over the blade ends (see Fig. 9). The operating rods 13, of which one is provided for each blade, are also inclined at the'r upper ends in the direction of card feed and each rod normally contacts with the clear space on the under side of the tip 128 of its corresponding blade. When any rod 13 is raised, as illustrated for the seventh rod from the left in Fig. 9, it raises its corresponding blade and all above it to provide a passageway for the card which happens to be feeding.

The operation of the actuating members 13 under the control of analyzing brush 15 will now be explained in detail. The auxiliary mechanism provided for controlling the actuating members 13 (see Fig. 2) is mounted upon a frame comprising

side plates

16 and 17 and a base plate 18 which in turn is mounted upon the frame of the sorting machine. The top plate 19 supports posts 20 which in turn carry a pair of plates 21. The actuating members 13 (see also Figs. 4, 5 and 6) are guided between the plates 21 one of which is provided with projections 22 (see Fig. 5) between members 13. The members 13 are also guided in slots formed in top plate 19. At their lower ends the members 13 have a notch providing a shoulder which normally rests upon the edge of curved plate 23.

A shaft 24 is coupled with the shaft 25 which is driven from shaft 8 by means of worm wheel 26 (see Fig. 2). The ratio is such that shaft 25 makes half a revolution for each machine cycle, that is, for each revolution of shaft 8. Fastened to shaft 24'which has its bearings in the side plate 17 is a cam disk 27 (Figs. 4, 7 and 8) to which is fastened a drum 28 journalled at its opposite end in the side plate 16. Within the drum is provided a rod 29 carrying controlling members 30 (see also Figs. 5 and 6) which have a slot in their central part through which rod 29 passes to slidably support the members. The members 30 pass at their opposite ends through slots in the wall of drum 28 and are angularly displaced with respect to each other so as to provide twelve actuating ends on each half of the periphery of the drum. A small pressure spring 31 (Fig. 8) is interposed between pairs of the elements 30 to provide a slight friction between the members and the slots in the drum 28 so that the members 30 do not move to and fro unnecessarily when the drum is rotating. Holes 32 in the drum 28 serve to permit insertion of springs 31 and observation of the parts during assembly. The magnet 33 is under the control of the analyzing brush and attracts its armature 34 which is fastened to a pivotally mounted shaft 35 when the magnet is energized.

At one end of shaft 35 (Figs. 2, 4, 5 and 6) is fixed a lever 36 having a square head portion 37 which cooperates with another head portion 38 provided on a pivotally mounted lever 39. In the normal position as shown in Fig. 5 the pivoted lever 36 is held by spring 40 in the position shown, with head portion 38 held in its lower position by head portion 37 thus latching lever 39 in the position shown against the pressure of spring 41 which tends to rock it counterclockwise. The lever 39 is further provided between its ends with a lug 43 which cooperates with the cam disk 27 to restore the lever 39 when it has been 1 released in consequence of energization of magnet 33 (Fig. 7). A lever similar to lever 39 is pivoted opposite it on side wall 16 and these levers are connected by a bail (Fig. 4) which is pivoted to each as indicated at 44 (Fig. 6). The bail 45 extends below the drum 28 and a spring 47 normally tends to turn it in clockwise direction as viewed in Fig. 6. It is held in vertical position, however, by lug 43. The lever 39 is provided with a spring 48 which cooperates with a shock absorbing member 49 of felt or similar material when the lever 39 is released by lever 36.

It has been explained that the drum 28 makes half a revolution for each machine cycle so that when the analyzing brush is searching the different index point positions of the record card the controlling member 30 corresponding to the index point position in analyzing position will be in vertical position between the controlling bail 45 and the corresponding actuating member 13. If therefore there is a perforation at a certain index point position the magnet 33 will be energized and the lever 36 will be turned in clockwise direction against the tension of the spring 40 which tension may be adjusted if necessary by adjusting screw 50. The head 37 will release head 38 of lever 39 and this lever and accordingly also bail 45 will swing upward under the pressure of spring 41. This will cause the particular controlling member 30 to be raised by the bail and in turn raise the corresponding member 13 which thereupon raises its own blade 11 and those above it to provide the proper distributing passageway for the card being analyzed as illustrated in Fig. 9.

To ease and limit the movement of member 13 spring plate 52 (Fig. 6) is provided coacting with a notch in the member. The lifted controlling element 30 will remain in its shifted position in consequence of the friction derived from spring 31 until it is restored to its central position. This is done by curved plate 51. The configuration of the plate is such that its surface gradually approaches the revolving drum. Consequently any member 30 which is displaced will be gradually returned to its normal position by the plate 51 as the drum rotates and will be in normal position before it again reaches bail 45. A similar curved plate 23 serves to steady the members 30 as they are thus restored.

At the end of each machine cycle one of the.

' bail 45 to normal latched position. It will be recognized that the lever 39 remains in raised position until the end of the machine cycle and that therefore the bail 45 will be encountered by all following controlling elements 30; but this bail being pivoted at 44 and tending to be drawn in clockwise direction by spring 4'7 will slide over the ends of the following members 30 and hence only the one originally in operative relationship will be affected.

Another embodiment of the present invention using the same principle of the controlling drum is illustrated in Figs. 17 and 18. In these figures the same reference numerals with the primes added are used for parts similar to those in the previously described figures so that no special explanationof the function of these parts is neces sary. According to this embodiment the drum 28 is provided on its rear end with a toothed wheel 54 meshing with a toothed wheel 55 carried by a shaft 56. Loosely mounted upon this shaft is a star drum 57 which is frictionally driven by the shaft 56 by means of a pressure spring 58. The armature 63 of magnet 33' is pivoted upon a plate 64 which has sharp portions on its upper ends and a rod 58a between which the armature 63 is pivotally located. It is held on its rear end by a spring 59 and limited in its clockwise movement by screw nut 60 provided on a guiding post 61.

In the normal position as shown in Fig. 18 the hook 62 of the armature 63 cooperates with a tooth of star drum 57 and consequently stops this star drum while in the same position another tooth is just below the controlling element 30 of the controlling drum 28'. If, however, the magnet 33 is energized under the control of a perforation in the record card, the hook 62 will release the star drum 57 which will turn under the influence of its frictional coupling with shaft 56. During the conjoint movement of star drum 5'7 and controlling drum 28'the controlling element 30' will be moved towards the actuating member 13' and will lift this member to provide for the separation of the sorting blades. As the spring 59 will at once restore the armature 63 after the deenergization of magnet 33' the hook 62 will again catch a tooth of the star drum 5'7 and stop the same, and another tooth of 'the drum will be in position to actuate a member 30 during the next machine cycle. It will be seen that the star drum 57 cooperates only instantaneously with the corresponding controlling member 30 and that there is no interference between this drum and the controlling members 30 following the original controlling of one of these members.

Start and stop mechanism It is well known in record controlled machines to provide a special start key and corresponding start contacts and a stop key with contacts governing the motor circuit of the maas well as by a lever which is under the control of the record cards passing through the machine and which lever closes the contact as long as cards are being fed through the machine. The device, as illustrated in Figs. 11 and 12, comprises a key lever 65 provided with a start key portion '18 and a stop key portion 80. The key lever 65 is fixed to a shaft 66 which also carries a bell crank lever 67. A spring 73 normally holds the stop portion 80 of the key lever depressed and the bell crank 67 to the left as viewed in Fig. 11.

The controlling contacts 79, whose arrangement in the motor circuit will be explained later, are mounted on spring blades 69 which are suitably anchored to an insulating block at their lower ends. At a small distance from their upper ends the spring blades are offset to cause their upper ends to converge. This provides flat parallel portions closely spaced and carrying the contacts 79 at the upper ends and flat parallel portions widely spaced at the lower ends, the two portions being joined by the converging slanting surfaces forming the offsets. A link 71 is pivoted to the horizontal arm of bell crank 67 and carries an insulating block 72 which slides between the blades 69. A card lever pivoted at 75 has one arm 74 extending into the path of feeding cards in the well known manner and another arm 76 carrying an insulating block 77 coacting with the contact plates 69. The vertical arm of the bell crank 67 has a sidewise extension 68 coacting with the insulating block 77.

In the normal position of parts, with no card affecting the card lever 74--76, the insulating block 72 is held between the closely spaced upper portions of spring plates 69 opening the contacts 79. Depression of the start key portion 78 of key lever 65 rocks bell crank 67 clockwise against action of spring 73. Lowering link 71 and sliding block 72 to the lower widely spaced portions of the blades 69 in which position it will allow contacts 79 to close. Incidentally extension 68 encounters insulating block 77 and rocks card lever 7476 to close contacts 79. The start key portion 78 must be held down until the first card encounters the card lever and thereafter the card lever holds the contacts closed as long as cards are feeding. As soon as card lever 7476 encounters no card, however, meaning that cards have stopped feeding the resiliency of the left hand blade 69 opens contacts 79 rocking card lever 7476 clockwise. It will be noted that as soon as hand pressure is released from start key portion 78, spring 73 tends to rock the parts back to normal position.

When the contacts 79 are held closed by the card lever, however, the sloping portions of the spring blades 69 hold the insulating block 72 down and the spring 73 stretched with stop key portion 80 of the key lever elevated. If it is desired to stop the machine while cards are still feeding and holding the card lever down, stop key portion 80 may be depressed. This forces block 72 upwardly camming spring plates 69 apart, to open contacts 79, the right hand plate 69 yielding in this case as the left hand plate is held by the card lever.

Circuit diagram The circuits of the sorting machine may be connected with the current source by the main switch 84 which is provided on the front of the sorter (see Figs. 1 and 16). Another switch 185 (Fig. 1) which is not shown in the diagram may be provided to connect a transformer with the current source if alternating current is used. The driving motor- 85 may be connected with the

main lines

86 and 87 by relays 88 and 89 which are under the control of magnets 90 and 91. In the circuit of these magnets is arranged the contacts 79 which are under the control of the card lever 74 and of the key member 65 as has been previously explained. The sorting circuit comprises the sorting magnet 33, the contact roll 92, and the usual commutator 93 which serves to select only certain index point positions for sorting operation. Brush 15 analyzes the record cards while brush 94 supplies current to the contact roll. The condenser 95 serves to reduce sparking on the brushes. As usual in circuits of electric accounting machines resistances 98 are provided. A signal lamp 97 is directly connected to the

main lines

86 and 87 and is located in the housing 98 (see Fig. 1) the front door of which has a glass plate insert 99. When the main switch 84 is closed this lamp will be lighted and thus indicate to the operator of the machine that the sorter is under voltage.

When the machine is to be started the operator depresses the start key 78 of member 65 and contact 79 will be closed by the lever 67. The card feed will be initiated and the first card will turn the lever 74 counterclockwise to hold contacts 79 closed and they remain closed as long as cards run through the machine. The magnets 90 and 91 therefore will be energized and remain energized thus closing the contacts of relays 88 and 89 and connecting the motor 85 to the

main lines

86 and 87. When there is a perforation in the position of the record card a current impulse will be effected from main line 86 over commutator brush 100, the corresponding selecting member 101 of commutator 93, second commutator brush 102, analyzing brush 15, contact roller 92, brush 94, resistance 96 and sorting magnet 33 to the main line 87.

Miscellaneous The new sorter is provided with a guiding member for the cards to guide the same before they reach the sorting blades. This guiding member 103 (Fig. 2) is arranged adjacent the path of the record cards passing through the machine. The member 103 is provided on its front end with a lip 105 having an inclined surface which prevents buckling of the cards and feeds them flatly to the sorting blades. Member 103 is pivoted on shaft 106 and rests upon rod 107. The height of guiding member 103 and guiding lip 105 respectively, may be adjusted by means of an adjusting screw 108. When it is necessary to inspect the front end of the sorting plate the glass cover 104 may be opened and lever 103 may be turned in counterclockwise direction.

A special safety device is provided to prevent damage to the glass plate which would be possible if the glass cover could be closed while lever 103 is not in proper position. On one side of the sorter (see Figs. 13 and 14) is pivoted a lever 109 into a slot in which passes a pin 110 provided on the end of the shaft 106 which carries the guiding lever 103. Upon the shaft 111 which is fixed to the glass cover is provided a cam member 112 which encounters the lever 109 if the glass cover is in open position as may be seen from Figs. 13 and 14. Normally lever 109 is in the position shown in dotted lines but when the glass cover 104 is in open position and the lever 103 turned counterclockwise (according to Fig. 2) the lever 109 will be shifted by pin 110 into the position shown in Figs. 13 and 14 where the cam member 112 encounters the lever 109 if an attempt is made to close the glass cover before the lever 103 has been restored again to its normal position. In the new machine provision is also made to prevent damage of the glass cover by quick dropping of the same. The device used for this purpose is schematically shown in Fig. 15. The glass cover 104 is carried by a metal frame 113 which bears a member 114 rockable about shaft 111 which shaft has its bearings in frame member 115 connected to the frame 116 of the sorter. Several members 114 may be provided along the shaft 111 and one of these members, preferably in the middle of the machine, cooperates with the damping device. The member 114 carries on both ends side plates 117 which in turn carry a shaft 118 which cooperates with a bar 119 having a bent end 120. On its lower end the bar 119 carries a shaft 121 which has a plunger 122 guided in the cylinder 123 filled with oil or any other suitable damping material. On the upper end the shaft 121 is provided with a collar 124 and between this collar and the cover plate of the cylinder is provided a pressure spring 125 which holds the bar 119 and its bent end 120 respectively in engagement with the shaft 118.

When the glass cover 104 is in open position bar 119 will also be raised slightly and if the glass cover 104 is suddenly dropped the shaft 118 will encounter the bent end 120 of bar 119 and the spring 125 will absorb the shock. Then in consequence of the gravity of plate 104 the piston 122 will slowly drop and spring 125 will be depressed accordingly until the glass cover has reached its closed position.

Conclusion The record cards are picked from the stack 2 and fed through the machine by the transport rolls which'are driven in unison from the driving motor 85'. The cards are analyzed by the analyzing brush 15 which controls the sorting magnet 33 which in turn cooperates with a controlling drum as has been explained. This controlling drum controls the sorting blades and separates the same to provide a passage corresponding to the perforated data of the record card. The card is then fed between the selected sorting blades in the usual way to the corresponding receptacle. Towards the end of the machine cycle the controlling parts of the drum are restored to their normal positon in readiness for the next analyzing cycle.

While there has been shown and described and pointed out the fundamental novel features of the invention as applied to several modifications it will be understood that various omissions and substitutions and changes in the form and details of the devices illustrated and in their operation may be made by those skilled in the art without departing from the spirit of the invention.
