  • the sorting machine is constructed as follows:
  • a card feeder i moves the cards one at a time in the usual manner under a reading comb 2, consisting of four needles 3, 4, 5 and 6, assem- 20 bled on springs in a frame, laterally movable in order that it may be led above the card column to be sorted. Furthermore, in line with the lines of the holes of the card (underneath the punch holes) four plates 1, 8, 9, ll (Figs. 1 and 2) 25 rest on the rods II, l2, l3 and I4. These plates are held at their ends by small levers i! (Fig.
  • FIG. 4 four parts of a parallelopiped 24, 25, 26, 21, and a fifth one 28, which is part of the frame, can, with the exception of 2B, which is fixed, slide one over the other. These parts are all pulled in the direction of the progress of the cards by the pairs of springs 23, 39, 3
  • the latter are integral parts of the levers 23, 2
  • the parts 24, 25, 26, 21 are moved by the springs 29, 30, 3
  • the movement of the part 26 relatively to the part 21, is twice as long as that of the part 21 55 relatively to the frame, and the relative movement of the part 24 is double that of part 25.
  • the part 24 has an extension 53 (Figs. '1, 4, 5, 6) in which a hole is bored (square for example) 54 and through which passes a rod of similar shape 55 having a shoulder 56 and held towards the lower end by a spring 51, resting on the screw head 58.
  • This rod 55 ends at its upper part in a beveled fork 59.
  • the screw head 58 is placed a fraction of millimeter above a plate 95 (Fig. 1).
  • plate 95 By the means of a bell crank 6
  • a cam 89 fixed on the main shaft operates, by means of a rod 99 and a lever 94, which at the desired moment returns the part 53 and then the parts 24, 25, 26, 27 into a position of rest against the stops 25, 26, 27' held, respectively, by 25,26, 21.
  • the above described device may be modified so as to facilitate or permit an increase in the speed of operation. Accordingly, the partial assembly, according to Fig. 4, and the shape of the blades (Figs. 7 and 8) are changed as follows: the parts such as 24, 25, 26, 21, are divided into two identical series; one remains unaltered, whereas the other is placed perpendicularly to the first. In Figs. 9 and 10, the two first parts of these series are shown by I9I and I92 and the other twoby I93 and I94. The part I9I is extended and four rodsv I95, I96, I9'I, I98, pass 9) and seen in profile (Fig. 10); they slide vertically in I9I and are brought back individually downwards, by draw-springs such as 204.
  • the part I93 is also extended and is fitted with a plate I99 the dimensions of which according to the plane of Fig. 9, are equal to the width of the rods I95, plus the total possible displacement of the parts I III and I92.
  • the plate I99 is placed above a plate 95, which corresponds to plate 60 in Fig. 1 but is widened so as always to meet the plate I99 whatever the positions of the parts I93 and I94 may be.
  • , 22, 23 of these figures are actuated by the rods II, I2, I 3, I4 (Fig. 1) in the manner indicated above or in any suitable manner.
  • the blades 66, 67, and 68' have been modified as will be shown in Figs. 11 to 15. They are not narrowed down as shown in Figs. 7 and 8, but holes of variable dimensions are bored through them; the upper blade is not bored at all, the blade that holds it, is bored along the axis 299 and of a single length; the two following blades are bored along the same axis and of double, triple length, respectively, and all the other blades have all a hole bored along the axis 290 and of a quadruple length, as is indicated in Fig. 12, which shows a cross section along the axis 299 of Fig. 11.
  • the second series of four blades has holes bored along the axis ZOI (Fig. 13), and is similarly disposed. This applies as well tothe third series (Fig. 14) and the fourth series (Fig. 15). Then the rods I95 I98 are, respectively, in the plane of 209 293 and the movements of I9I are parallel with these planes.
  • the drive of the levers 29 23, whether it applies to the device of Fig. 4 or to the modification shown in Figs. 9 and 10, can operate differently than that shown in Fig. 1, and particularly, this drive can be effected by using cards punched with only one hole per column. In this case as many exploring needles or rods are disposed per column, as there are possible positions to punch in that same column, and this needleor rods drive, by means of suitable 'devices, oneor many rods II I4, depending on the position of the perforation or punch.
  • the carriage card holder consists of a plate :3 (Fig. 16) shaped like a grid without cross bars, the longitudinal bands being separated by twice the distance between two consecutive columns of the card.
  • This plate has slides 14, which hold it in the frame of the sorter; it has extensions l5, retaining the cards in the stack when the carriage is in a forward position; it has a lever TI and the tilter I8.
  • This tilter I8 is bent back at its lower end in 19 (Fig. 1'7).
  • the dog 19 rests on the rib 80 of the frame (Fig. 18). The length of this rib is less than the length of the travel of the carriage 13, so that, at each end of the travel or the stroke, the dog I9 is freed of the rib 8%.
  • the feed spring '56 consists of a very flexible blade fixed at its center on the carriage I3 in order to overcome a possible adhesion of the cards. It has also two feeding embossings.
  • This carriage feeds a card in a forward movement untilit rests on the grid 86; during this movement, the card is pushed under two springs 81 (Fig. 20) (one on each side of the device) fixed at 88. Due to the provision of stop 95, the springs retain the card to remain on the grid 85 when the card holder backs up.
  • the tilter During the period of rearward movement of the carriage, the tilter 18, after bumping against the ribtli), operates the lever H, in order that the nose 82 disappear and pass under the card that is being read on the grid 88, without hooking it at the end of its stroke.
  • the tilter i8 is freed and. the nose 82 comes up.
  • a new card is fed by means of a spring I6 and the preceding card will be pushed by the nose 82 until it is taken be tween two rolls or fed through fingers fixed on an endless chain.
  • the main shaft carries a distributor I02 (Fig. 22) and its brush I83 engages the contacts I04, I05, I35, I61, while the four lines of holes of the card pass under the brush 9-1.
  • the current flows from the source I88 through the brush I03, terminals IM to I01 to one of two windings of the relays Hi9, Hll, HI, H2; then it returns to the source through the brush 9? and the holes of the card.
  • the relays IE9 to H2 close through their secondary winding,a holding circuit in H3, H4, H5, I56, H1, H8, and in H4, I23, I24, I25, I26, the energizing circuit of the electro-magnets HQ, IZII, I2I, I22; these last electro-magnets actuate, respectively, the levers 2E) .23 and thus replace the rods II Id.
  • the balance of the device is identical with that of Figs. 1 and 4 or 9.
  • An interrupter I21 connected in the return wire common to all the electro-magnets opens'for an instant at the opportune moment, under the control of a finger I28 fixed on the main shaft.
  • An interrupter which can be short circuited, is provided at I41 and I48.
  • the electro-magnets H9, I20, I2I, I22 are assembled as it is shown for one of them in Fig. 23; its armature I29 rests on the lever 29 (Figs. 1, 4 and 9) furthermore, a cam I33, fixed on the main shaft, makes the armature rest upon the core, by means of rods I30 and I32, and of the bell crank I3I this mechanical contact lasts only for a very short time and takes place as soon as the relays I09, H0, III, H2, have functioned and during the action of the cam 89' on the lever 94.
  • the energized electro-magnets will continue to free the parts 26, 25, 26, 21, after the setting back of the lever 94, while the others will have let go their armature before this set back.
  • the finger I28 opens the circuit of the electromagnets and relays, and all the parts return to the original position.
  • the sorting means On operate the sorting means on several columns at a time, i. e., to sort only cards in which a certain number of columns has been predetermined, the other cards going into the reject compartment XVI, the following device is used:
  • the rod 90 (Fig. 24) has a slot I31, in which a bolt I39 engages, held by the armature of the electro-magnet I38. It will be clear that if that electro-magnet is not energized when the cam 89 frees the rod 98, the latter will remain blocked by the bolt I39 which will be raised under the action of the spring I89 at the moment when the slot I3! above it is passed. When the magnet is energized the rod 98 will respond to a spring and will free the parts 28, 25, 26, 21.
  • each needle 3 is equipped with a sheath consisting of a middle part MI of conductive material disposed between two insulated parts I42 and I43 (see Fig. 25).
  • the springs I45 and I46 are short circuited by the sheath I II, thereby closing a circuit through a relay which frees the selector corresponding to the lowered needle.
  • the two springs I44 and I45 are short circuited and close a circuit through the electro-magnet I38 (Fig. 24) in order to free the push back arm 99.
  • the device compares the relative values of two numbers preferably modified as follows (Fig. 27):
  • a series of four needles such as I86, I8I, I82, I83 are provided, each forming a commutator due to an insulated sheath conductor placed between two insulated sheaths, and two identical series or" four resistances I84, I85, I86, I87, and I84, I85, I86, I81, the values of which are as follows:
  • the free end of the resistance I84 is connected at I88 to a contact of the source of current, and the free end of the resistance I84 at I89 to the other contact, while the free ends of the resistances I8! and I81 are united in a point I90, which point will be connected to a terminal of a polarized electro-magnet.
  • this device constitutes a potentiometer which gives for each combination of holes, passing under the needle, a tension which increases in arithmetical progression between the points I89 and I 98 for example, and decreases equally between I90 and I88.
  • the device disclosed in said French Patent 619,625 and which permits simultaneous sorting on several columns, has the great advantage to give in one passage through a sorter a group ,of perfectly and finally sorted cards without altering the order of the other cards. After use the cards contained in that group must be refiled in their original order. In the case where the group consists only of a few cards, the refiling can be done manually without the aid of the sorter. However, if a great number of cards are to be refiled or where the manual work becomes tedious and may lead to errors, even if written indications appear on the card, it will be necessary to put through all the cards to file them together with those which had remained in order, so that all will find their respective consecutive order. Several sortings are thus necessary and either a device is used to automatically insert the cards to refile them in their proper places, or to aid materially in the manual refiling. The description of such device follows: a
  • the see-saw movement driving the carriage is produced by a crank button I52, carried by a plate held on the main shaft of the sorter and penetrating in the vertical slot I53 of the connecting rod I54.
  • the latter suitably guided horizontally, normally interlocks with the lug I55 which is a part of the carriage card holder by means of the tilter I56 articulated at I51.
  • This tilter can assume two extreme positions, limited by the stops such as I58 and I59 against which it is maintained by the spring I66, which is tied at I6I on the connecting rod I54 and which is situated on the vertical line of the pivot I51 and above it.
  • two stops one I62 movable as will be explained, the other I63 fixed on the frame have for their object the tilting of the part I56.
  • the stop I62 is provided on the lever I64, and is urged by the spring I68 to turn around the pivot I65 fixed to the frame; this lever ends in I66 by a ratchet-motion held by the spring I61 and forming the armature of electro-magnet I69; in the position of ratchet-motion, the tilter I56 bumps against the lug I62; in the contrary case, the tilter passes freely above the lug. Then if the electromagnet I69 does not receive any current, the tilter I56 bumps against the lug, freeing the part I 55 and the carriage will not be driven any more by the connecting rod I54, during its return movement.
  • the embossing I10 acting on the lever I64 latches it with the spring I61, then the tilter I56 bumping against the button I63, takes back the hooking position of the bolt I55.
  • This hooking can be done, (if the electro-magnet I69 receives current) because the parts I55 and I56 are beveled; at the time of their hooking, the spring I66 acts, but not sufficiently for the tilting of the tilter I56.
  • the button crank I52 must be fixed and the distance between the compartment XVI and the distributor I56 must be determined in such a way that when the electro-magnet I69 receives its current at a definite moment, the separation card arrives in the compartment XVI at the same moment when the selected card would have arrived.
  • the central brush I13 of D is connected with the exterior circuit, that is, with the electro-magnets I69 and I38.
  • the positions of the needles A, B, C, D must be identical to the positions of A, B, C, D, and the current will not be able to pass.
