ALPHABETICAL SORTEB.

Application led December 3, 1924. Serial No. 753,561.

j This invention relates to improvements in machines for sorting perforated record cards such as are used in tabulating machines,v especially cards punched according to the Peirce alphabetical code.

In the Peirce system the reading position is a particular zone on a card., and the perforations are variously arranged in that zone instead of being positioned anywhere in a card column extending from top to bottom My present invent-ion is an improvement on the machine described in detail in copending application Serial "695,000, tiled February 25, 1924 on behalf of E. A. Ford which discloses a sorting machine designed to segregate in one run cards of the Hollerith type having certain combinations of holes in a plurality of columns.

My invention covers a sorting machine designed to segregate in one run cards having a certain individuality as represented by a particular combination of perforations on the card. For instance, it may be desired to separate from a promiscuous stack of cards all thosel bearing the name Brown, 0r all those bearing the name of a certain town, such as Atlanta, and that is the kind of work this present invention will do. It sorts cards electrically while the cards are in motion, depositing the. segregated cards in one stack and the rejected cards in another stack. My machine works rapidly, is easy to change from one set-up to another, is simple in construction, and inexpensive to manufacture.` Further and other advantages will hereafter appear in the accompanying specifications and claims and in the drawings, which by way of illustration show what I` now consider to be apret'erred embodiment of my invention.

In the drawings, e Fig. 1 is a sectional view of the machine. Fig. 2 is a front view. FFig. 3 is a sectional view on line 3- 3 of Fig. 4 is .a view of the card detlecting mechanism in deflecting osition.

Fig. 8 shows a side view of a modification of my invention designed to sort cards punched according to the Hollerith alphabetical code.

Fig.'9 is a front view of the modification` in Fig. 8.

Fig. 10 shows a portion of a Hollerith l card punched according to the Hollerith alphabetical code.

In the drawings, is the magazine containing a stackof record cards :trom which the cards are fed one by one, at regular intervals, b the picker mechanism 21, into control o the positively driven conveyor rolls 22. In their passage downwardly through the conveyor and analyzing device the cards are guided by slots in the edges of ixed plates 23.

.After a card leaves the bottom rolls of the 'conveyor it passes normally into control of' .into deflecting position by spring 31, when permitted by cam 33. Fingers 32, also fast on shaft 30, bearon cam 33 which is fast on one of the conveyor roll shafts.

Also fixed to shaft is an arm 34 which engages a notch in armature 35 of magnet 36. These parts are normally held,y in latched position by spring 37, as in Fig. 1. While the deiector is in this position all cards willpass to the reject pile.

When sorting magnet 36 is energized, armature 35 is drawn to the right, arm 34: is unlatched, andI lingers 32 rest on cams 33, as in Fig. 3, and deflector plates 26 are rocked by spring 31 at theproper time in the machine cycle to direct the card into pocket 29.

Th foregoing devices are commonly used,

in card sorting machines and require no further description.

l Analyzing device.

The gear trains which drive the feed rolls include upper :and lower pairs of gears 38 and 39 respectively. vA crank 40 is fast to each stud on which upper gears 38 are mounted, and a similar crank 41 on each stud of lower gears 39. Cranks 4() carry cross shafts 49. and 43, while cranks 41 carry cross shafts 44 and 45. Mounted on cross shafts 43 and 45 is a pair of side bars 46, and on shafts 42 and 44 a pair of similar side bars 47.

Supported by lugs 48 on bars 46 is a plughoard 49, and in al similar manner, plugboard 50 is carried by parallel bars' 47. These plug-boards are made of non-conducting material such as bakelite and are perforated so that each hole corresponds to an index position on the card.A llach hole in the plug-board is provided with a shell portion 50a adapted to receive a plug assembly 50h (see Fig. 5). The plug assembly is preferably removably secured in the plug-board shell by means of a bayonet joint 50. Each plug assembly comprises an outwardly spring-pressed contact plug 52 and a tap portion 5l. plug assemblies can be changed in their locations as desired and in accordance with the index perforations which are to be sensed. To facilitate removal and insertion of the plug assemblies they may be provided with Asuitable knurled heads as shown in Fig. 3.

When the machine is in operation the cranks 40 and 41 revolve in the direction indicated by the arrows in Fig. 3, bringing the two plug-boards into close proximity with each other once during every card cycle. Their movement is so synchronized with the balance of the mechanism and the card travel, that, during the time they are together and moving practically parallel with each other and with the card, every hole in both plug-boards registers with its corresponding card index position, and if any taps 51 are in position in the plug-boards their spring plugs 52 will contact with their corresponding index' positions on the card.

If there is a perforation in the card at any such index position the plug 52 will pass through that perforation.

\ Referring to the circuit diagram (Fig. 7), 53 is Aa switch admitting current from an outside source to the lines 54 and 55. 56 is the motor, controlled in the-manner custo.- mary in machines of this character. Depression of start key 57 closes a circuit from line 54 through the two stop keys 58, through relays 59 and 60 to line 55. Energization of relay 60 closes the motor circuit, which, after start key 57 is released, is maintained by card lever contact- 61 as long as cards are passing. Relay 59 closes this circuit when its magnet is energized. The motor will be stopped automatically by the opening of contacts 61 when the supply of cards is exhausted, or it may be stopped at 'the will ofl the operator by depressing either stop net 36 and cam contact devices 63 which are those generally used in machines of this class to make the circuit during the ypassage of af card and break it again at' a fixed point in the cycle. From the right Side of the contact combination 63 one wire 64 leads to the contact point of a relay 65 connected to line 55, while another wire 66 leads to the analyzing device. If contact is established through the analyzing device current will flow through inlet wire 66 and outlet wire- 67 to relay 65 which will be energized and will maintain a stick circuit in maofnet36 through wire 64 after the contacts throughthe cards are separated, thereby preventi g arcing at the cards. This circuit is final y broken at a set time in the machine cycle by contact device 63.

Operation.

Bv way of illustration, I have assumed.

thatu the operator has a promiscuous stack of cards and wishes to segregate all those bearing the name Brown. To accomplish this he wires the plug- boards 49 and 50 by means of taps 51 and their connecting wires so when a card bea-ring the combination ol perforations meaning Brown is in the analyzing device every plug 52 in plugboaid 49 will be in contact with its corresponding plug 52 in plugboard 50 through a hole in the card7 and a series circuit will therefore be established through inlet wire 66, the plug-board wiring, and outlet wire 67, so` that sorting magnet 36 will be energized and that card will be sorted. vThis' circuit may be readily traced in Fig. 7, in which plug-board 50, although normally straight behind board 49, has been, for descriptive the analyzing device above described.

purposes, swung up to a position above 49. Current passes from wire 66 through front tap No. 1 in the B column, comes out through the corresponding rear tap, and passes by the tap wire in the rear to rear tap No. 2 in the B column, from which it emerges through the corresponding 4front tap No. 2, then passes by front tap wire to front tap No. 5 in B column, and after coming out through the rear No. 5 tap it. passes t-o the N o. 5 tap in the next column, and so on, passing througlrall taps in series, spelling out the letters of Brown7 and finally emerging from rear tap No. 6 in the N column and passing by wire G7 to relay 65.

Now if the cards to be sorted are placed in magazine 2O and the machine started by pressing motor start key 57 the cards will be fed at regular intervals to conveyor rolls 22 and while passing downwardly through the conveyor each card will be examined the name Brown does not appear, the sorting magnet will not be energized, and the card will pass straight ahead into control of the stacking device and will be deposited thereby on the reject pile. If, however, the name Brown does appear, in the proper location on `the card, the circuit will be completed as above described, sorter magnet 36 will act, and defiector blades 26 will direct that card to the left ofy partition 27 so it will inally rest on pile 28 inpocket 29.

/If it be desired to sort under control of some combination of perforations in the bottom half of the card, another set of plugboards is installed in the position indicated by the broken lines in Fig. 2, and are wired for the desired combination of perforations.

" Modification.

Figs. 8, 9, and 10 show a modification ot my present invention. For purposes of illustration this modification is shown as adapted for sorting cards according to the Hollerith alphabetical code.` Plug- boards 49 and 50 are replaced by sets of parallel bars (39 and 70 respectively, there being one bar for each column of index positions on the Hollerith card. Bars 69 are of nonconducting material, while bars 7() are of metal, insulated from each other and from their supporting shaft-s 42 aud 44; Each bar (i9 carries two settable clips 71, each provided with a contact spring 72 and with a screw 73- for attaching a wile 74, also a locking device as indicated at 75 to secure the cllp to its bar. Each bar 69 has a marked position for each row of .index positions on the card, alsoi an extra position S below the 9 row. all as indicated on the bar 69 furthest to the right in Fig. 9.

In the`r Hollerith alphabetical code the letters are each represented by one or two perforations at particular index positions in the card column. T he perforations in Fig. 10 spell the name Brown, B'being represented by holes in XX and 8 positions, R by a single hole in row 4, O by a single hole in row 3, YV by holes at 5 and 9,7and N by 4holes in rows 2 and 9.

To separate from a pron'iiscuous stack of cards those having the above perforations, the operator .sets his clipsI 7l and connects them with wires 74, all as shown in Fig. 9. The path ot' the sorting current is through vwire (56 to clip at XX position then down the ($9 bar to clip att position, thence by wire 74 to `clip at S position on the next bar, thence through the bar to clip at position 4, thence through a wire 74 to clip on the next bar, and so on, until it finally emerges on wire 67.

1t is evident that only the combination ol' holes representing Brown will allow completion of the sorting circuit, consequently, as promiscuous cards are passed through the device only those punched Brown 1n theA last live columns of the Hollerith card will be sorted, all others being rejected.

In accordance with the provisions of the patent statutes, I have herein described the principle of operation of my invention, together with the apparatus which I now consider to represent the best embodiments thereof, but I .desire to have it understood that the apparatus disclosed is only illustrative and that the invention can be carried out by other means.
