Definitions
- This invention relates to printing machines and more particularly to perforated card controlled printing machines.
- One of the objects of the invention is to devise a printing machine capable of operating at a very high rate of speed.
- Another ob'ect is to devise mechanism for controlling the printing from perforated record cards in which the perforations in the card are in combinational arrangement and in which the mechanism is adapted to translate the combinational reading into its ultimate meaning at a high rate of speed.
- Another object is to devise a high speed printing mechanism in which it is unnecessary to restore the printing elements to normal position after printing has been offected in one cycle and before printing in the next cycle.
- Another object is to devise combinational translating mechanism which need not be restored to normal position before being set for controlling the printing mechanism in the next cycle.
- Fig. 1 is a side elevation showing the important parts of the printing machine.
- Fig. 1a is a detail of a part of a controlling device.
- Fig. 2 is a section taken substantially on line 22 of Fig. 1 on an enlarged scale showing three columns of printing type along with the controlling and operating mechanism associated therewith.
- Fig. 3 is an electrical commutator device used in connection with the reading of perforations in the control record cards.
- Fig. 4 is a diagrammatic representation of a device for converting combinations of perforations into definite readings and for setting the printing mechanism accordingly.
- Fig. 5 is a table indicating the various combinations of perforations used to represent different numerical and alphabetical, etc., characters.
- Fig. 6 is a modification of the device shown in Fig. 1 disclosing an electrical controlling device.
- Fig. 7 is a wiring diagram of the electrical control device shown in Fig. 6.
- Fig. 8 is a table showing a rearrangement type wheel is normally rotating constantly to cause the successive type elements to pass through printing position.
- the perforated record card is fed under an electric brush which upon sensing a perforation in the card closes an electric circuit which in turn effects the setting of stop devices.
- These stop devices control setting of several combinational combs.
- the mechanism which effects the rotation of the type wheel carries a stop pawl which is controlled by the setting of the combs and stops the rotation of the type wheel in a position controlled by the set up of the combs. This brings the particular type on the wheel into stop position in line for printing. This takes place for each column or printing wheel. After all of the printing wheels have been set in position for printing they are then snapped against the platen which carries a sheet of paper to effect printing upon such sheet.
- the type wheel 1 is shown as rotatably mounted on a carrying arm 2 and .is provided with a gear 3 fixed thereto.
- Gear 3 meshes with a pinion 4 rotatably mounted on the arm 2 and meshin with a gear 5 mounted on a shaft 6.
- ear 5 meshes with pinion 7 which in turn meshes with gear 8 carried on a shaft 9.
- gears 8 mounted on shaft 9 as there are columns of printing type or Wheels 1.
- the washers may be connected to a shaft through a groove 11 so as to be free to move longitudinally on the shaft and constrained to rotate therewith.
- the gears 8 on the other hand are freely mounted on the shaft 9.
- a gear 12 meshing with a ar 13 carried by a driving shaft 14.
- Sha 14 causes shaft 9 to rotate continuously'thus causing the washers 10 to also rotate continuousl
- the washers 10 are all pressed against t e gears 8 b a spring 10a and tend to turn the latter t us causing the type wheels 1 to rotate. Any of the gears 8 may be locked against rotation to stop the turning of the type wheel 1 to bring any of the type characters or elements 15 to a stop in the printing line.
- a ringlike member 16 Integral with the carrying arm 2 is a ringlike member 16 carrying several projecting pins 17 reaching through slots 18 in three combinational combs or rings 19, 20, 21. These combs have notches 22 arranged along their inner periphery and a pawl 23 (Figs. 1 and 4 ivotally mounted on the gear 5 is provi ed with a tooth 24 reaching across the inner peripheries of the three combs. As the gear 5 rotates the pawl 23 is carried around with the tooth 24 pressing against the inner peripheries of the combs 19, 20,
- the ring 16 is provided with a projection 27 having a spring 28 tending to turn it in a clockwise direction to rock the arm 2, thus moving the type wheel with the type 15 into cooperation with the platen 29.
- a rod 30 carried between arms 31 mounted on shaft 6 normally holds all of the arms 27 in the position of Fig. 1 thus holding the type wheels away from the platen.
- a link 32 is provided with a cam follower 33 cooperating with a cam 34 fixed on the drive shaft 14. Once during each cycle of operation a depression 340 in the cam permits the link 32 to drop.
- the spring 28 w1ll then snap the printing wheel against the platen to effect printing.
- a frame 35 carrying several sets of setting stops 36, 36a, 36b, 37, 37a, 37b, 38, 38a, 38b.
- the stop 36 is provided with a'spring 39 tending normally to move it to the right.
- An arm 40 on the stop 36 cooperates with pins 41 on the stops 36a and 36bto move the latter stops to the right also as viewed in Fig. 1.
- Stops 36a and 36b cooperate with latches 42 pivoted at 43 to the frame 35.
- a spring 44 connected between stop 3602 and the latch 42 tends to hold the latch in cooperation with a shoulder 45 on the stop 3611).
- Stop 36 is similarly constructed and is also adapted when released to move the stop 36 to the left. Stop 360 may thus move to the left carrying stop 36 and leaving stop 36b in its normal position to the right, or the stop 366 may move to the left with stop 36 leaving stop 3601 in its normal position to the right. If neither stop 36a nor 36?) moves to the left then stop 36 also remains in its position to the right.
- the combination combs 19, 20, 21 are provided with projections 1901, 200:, 21a.
- the projection 19a is adapted to cooperate with any of the stops 36, 36a, 36b.
- the projection 20a is ada ted to cooperate with stops 37 37a, 37b an the projection 21a is adapted to cooperate with stops 38, 38a, 38b.
- the frame 35 is connected to one or more links 46 provided with cam followers 47 cooperating with cams 48 carried by the driving shaft 14. Frame 35 is thus moved clockwise about shaft 6 a distance controlled by the cam 48 and then moves back to its normal position as in Fig. 1. As the frame moves upwardly, if stop 36 is in its outer position, it will enga e the projection 19a rocking the comb cloc wise around shaft 6. The distance through which stop 36 moves the .comb 19 may be designated as 3 steps. If, however, the stop 366 has been released by its latch 42, carrying stop 36 with it, then the stop 36a will engage the pro'ection 19a to rock the comb 19 two steps. If the stop 36a has moved to the left with the stop 36, then the stop 36b will engage projection 19a.
- the projection 20a is similarly controlled by the stops 37, 37a, 37b to set the comb 20. If stops 37a and 37 I) both move to the left with stop 37 then stop 38 will move into engagement with projection 20a without shifting the latter. Projection 21a is controlled in the same manner by stops 38, 3801, 386. A special stop 49 is provided to engage projection 21a when the stops 38, 38a, 38?) have all moved to the left. It should be noted here that the projections 19a, 20a, 21a are of different lengths which is also true of the sets of stops 36, 37, 38.
- the stop 36 will not interfere with projections 210., 20a.
- the stop 37 interfere with projection 21a.
- the stops 36, 36a, 36b have all moved to the left and stop 37 has also moved to the left, the latter stop will still be in position to engage projection 19a without moving the latter. In other words, when the stop 37 moves to the left so as not to effect a setting of projection 20a, it is still long enough to cooperate with rojection 19a.
- the ring 16 is provided with a projection 50 on which is pivotally mounted a latching pawl 51 actuated by a spring 52 into cooperation with ratchet teeth 53 rovided on each of the combs 19, 20, 21. he pawl 51 prevents turning of the combs under the influence of their springs 54.
- Integral with the frame 35 are arms 55 provided with a cross rod 56 adapted to engage a-projection 57 on the pawl 51.
- the rod 56 engages all of the pawls 51 rocking them out of cooperation with the teeth 53. The reason for this is that one or more of the combs may have been set in a position during the previous cycle, a distance greater than it is to be set durin the current cycle and will have been locke in such position by the pawl 51.
- the stops 36, 37 or 38 will not on their upward stroke engage the projection on such comb to move the latter, but as the frame 35 approaches the end of its stroke, the rod 56 will move the latches 51 releasing all of the combs so that those that may then be in position beyond the reach of the stops 36a or 37b, for instance, Will now be released to be moved by their springs 54 into cooperation with such stops, thus receiving the proper setting for the current cycle of operation.
- the rod 56 is also adapted to engage an arm 58 pivoted at 59 and provided with a projection 60 adapted to cooperate with the teeth of gear 8 to stop their rotation.
- the stoppage of the gears 8 in this manner takes place just as the combs 19, 20, 21 are being set. This stops the travel of the pawl 23 so that it will not tend to drop into any of the notches 22 until the setting of the combs has been completed.
- the rod 56 begins to return to its normal position, it will release the arm 58 thus releasing all of the gears 8 to permit the parts to again rotate.
- the pawl 23 then will commence to travel in a clockwise direction until it finds a position in which notches 22 in the three combs are in alignment.
- the pawl will drop into the notches at one end and engage the ratchet teeth in wheel 26 at the other end.
- the engagement of the ratchet teeth 26 causes the stoppin of the gear 5 and type wheel 1.
- the bar 30 will be dropped to permit the springs 28 to snap the type wheels up against the platen to effect the printin
- the setting of the various stops 36, 3 38 is efiected under control of perforated record cards 61 which are fed one after another by feeding rollers 62, 63 which aredriven by pinions 64, 65. These pinions are driven by a gear 66 meshing with a pinion 67 on the driving shaft 14.
- the cards are fed downward y between a common contact roller 68 and a sensing brush 69.
- the roller 68 is electrically connected by a wire 70 to one side of an electromagnet 71.
- the other side of this magnet is connectedby wire 72 to one side of a source 73.
- the other side of this source is connected by a wire 74 to the sensing brush 69.
- the armature 75 of the magnet 71 carries a plunger 76 ada ted to reach into the path of theseveral latc ing members 42.
- the frame 35 is moved upwardly synchronously with'the feeding of the card under the sensing brushes 69.
- Each brush 69 cooperates with one column on the record card 61.
- Each column is divided into six index point positions according to the arrangement of Fig. 5.
- Perforations in various combinations in any particular column are adapted to represent various values.
- a corresponding one of the atches 42 will be approaching the plunger 76.
- the magnet 71 will be energized moving the plunger 76 into the path of theparticular latch 42.
- the latch 42 passes the plunger 76, the latch will be rocked out of cooperation with the stop 36a or 36?), etc.
- the plunger 76 is immediately restored to its normal position out of the way of the next latch 42 so as not to interfere with it.
- the plunger 76 will be set again before the corresponding latch 42 reaches it so that such latch may be rocked. In this way, as a given column passes under the sensing brush 69 one or more of the latches 42 will be tripped depending upon the combination of perforations in that column.
- the duration of energization of the magnet 71 is equal to the time that it takes for the perforation to pass under the brush 69. As soon as the brush rides out of the perforation breaking the circuit, the magnet becomes deenergized and a spring 77 will restore the armature and the p un er 76 to normal position.
- an additional electromagnet 78 may be provided on the opposite side of the armature 75. One side of this magnet is connected to wire 72 while the other side is connected through wire 79 to a brush 80 cooperating wlth a commutator 81. Another brush 82 on this commutator is connected by wire 83 and wire 74 to the other side of the source.
- the commutator 81 is mounted on a shaft 84 on which is fixed a gear 85 meshing with a gear 86 on the driving shaft 14.
- the commutator is provided with six, contact segments 87 connected to a common contact strip 88.
- the brush 82 is constantly in contact with the strip 88 and the brush 80 is timed to engage each of the segments 87 just after the brush 69 has ridden out of a perforation in the card to break the circuit through magnet 71.
- the com- ,mutator 81 thus energizes the magnet 78 as soon as magnet 71 becomes deenergized. This will effect a quicker and more positive restoration of the plunger 76 than would otherwise be efi'ected by spring 77 alone.
- the plunger 76 after having tripped one of the latches 42 will be restored very rapidly and will thus permit a more ra id operation of the frame 35.
- this shaft may be fixed to the arms 31.
- the ratchets 26 are rocked an equal distance.
- the pawls 51 carried by rin 16 cause the combs 19, 20, 21 to move a slmilar distance.
- Gears 5 are then permitted to turn an equal distance due to their constant tendency to turn and helped by the cooperation of the combs with pawl 23.
- the corresponding movement of gear 5 makes it unnecessary for pinion 4 to roll on gear 5 and change the position of the type wheel.
- Fig. 6 I have shown a modification of the device in which six combs 89, 90, 91, 92, 93, 94 (see also Fig. 7) are employed. These combs are provided with projections 95 of different lengths reaching into the paths of movement of six stops 96 carried by a frame 97.
- the stops 96 are normally held in their upper osition by latches 98, springs 99 being provi ed to hold the latch in operative position.
- the frame 97 is connected through an arm or arms 100 to rocking arms 101 which in turn are connected by links 102 having cam followers 103 cooperating with cams 104 on the operating shaft 14.
- the frame 97 moves to the left synchronously with the feeding of the card 70'so that as each index point position on the card passes under the sensing brush 69, a corres onding one of the latches 98 will be approaciiing the plunger 76.
- Energization of magnet 71 will set the plunger 76 to rock the latch 98, releasing correspondin stop 96 which will be moved downwardly by the spring 99.
- Each of the stops 96 cooperates with a corresponding one of projections 95.
- the frame 97 When the frame 97 reaches the end of the stroke to the left those of the stops 96 that are in their upper position will engage their projections 95, moving the combs 89, etc., slightly to the left.
- the frame 97 will engage a link 105 rocking the latch 106 out of cooperation with the combs 89, etc.
- a stop 96 has been lowered by reason of the setting of the plunger 76 corresponding to the perforation in the column on the card, a corresponding projection 95 will not be engaged by the plunger 96 so that when the latch 106 is lowered, it will release that particular comb to permit the latter to be moved to the right under whe action of its spring 107 until a stop projection 108 engages a stop bar 109.
- the frame 97 starts back to its normal position to the right immediately, thus permitting the latch 106 to move back into cooperation with the combs 89, etc. Those combs which have not moved one step to the right will thus be relocked in their normal positions while those that have moved to the right will remain in such position. If any of the combs 89, etc., had moved to the right during the previous cycle they will not be restored until the stops 96 in the current cycle engage the projections 95 to move the combs to the left. Any combs thus restored will be latched in such position when the latch 106 moves upwardly. Combs 89, etc. are provided with notches 110.
- Three of the combs 89, 90, 91 cooperate with contact operating fingers 111 and the other three combs 92, 93, 94 cooperate with another set of contact operating fingers 112. Whereever three of the notches 110 in the combs 89, 90, 91 are in alignment, corresponding finger 111 will drop into the notches, thus closing contacts 113 and wherever the notches in the three combs 92, 93, 94 are in alignment a corresponding finger 112 will drop into the notches closing contacts 114.
- the various sets of contacts 113, 114 will be closed thus establishing a circuit through an electromagnet 115 at a time in the operation of the type wheel 1, depending upon which of the contacts 113, 114 are closed which in turn, of course, depends upon the particular arrangement of the perforations in the column on the record card 70.
- the contacts 113, 114 are variously connected to several commutator brushes 116. These brushes cooperate with commutator 117 mounted on the shaft 118 on which is also fixed a gear 119 meshing with the gear 5.
- the fingers 111, 112 are provided with springs 120 tending to lower them into the notches 110. If a finger is in its lowered position in the notches, movement of one of the combs 89, etc., will cam the finger out of position to permit the corresponding contacts 113, 114 to open. After the combs have been set under control of the reading of the card and the contacts 113, 114 close to correspond to the perforations in a particular column, the rotation of commutator 117 will thereafter close the circuit through electromagnet 115 at a time depending upon which contacts 113, 114 have been closed.
- the commutator 117 is provided with contact segments 121 which are interconnected by a conducting ring 122.
- the segments 121 are located at varying distances apart on the periphery of the commutator. At a particular point in the rotation of the commutator, two of the segments 121 will be simultaneously engaged by the first and ninth brushes 116. If the setting of the combs has effected closure of the first and ninth set of contacts 113, 114 then when the first and ninth brushes 116 are in contact with segments 121 a circuit will be closed from the positive side of the line to the first set of contacts 114 then through wire 123 to the first brush 116 then through the segments 121 and ring 122 to the ninth brush 116, the ninth set of contacts 113, wire 124, magnet 115 and back to the other side of the line.
- circuits representing the difl'erent characters arranged according to Fig. 8 will take place at different times according to the combination of brushes 116 as indicated by the table in Fig. 9.
- the first and second of the brushes 116 will be interconnected through the segments 121, and ring 122 and at the next point in the cycle, the second and third of the brushes 116 will be in position to close the circuit through segments 121 and ring 1 22 to the magnet 115.
- the successive points in the cycle at which the several brushes 116 combine to close the circuit through the magnet 115 are shown by this table of Fig. 9.
- Magnet 115 operates an armature 125 which acts as a latch for a pawl 126 carried by a branch 127 of the arm 2a.
- the pawl 126 is pivoted on this branched arm at 128 and is actuated by a spring 129 into latching position with respect to a ratchet wheel 130.
- the ratchet 130 is fixed with respect to gear 5 so that when the magnet 115 is energized the pawl 126 will be released to stop the ratchet 130 and gear 5, thus stopping the type wheel 1 for printing.
- Aprojection 27a on the carrying arm 2a cooperates with a rod 30a carried by arms 31a which are in turn actuated by links 320 having cam followers 33a cooperating with cams 345.
- the frame 97 will thus release the link permitting the latch 106 to cooperate with the combs to hold them in their set positions.
- a member 131 having a cam edge 132 is in position to be engaged by a projection 1.33 on each of the stop members 96 as the frame 97 moves toward the right. This will cam the stops 96 that may have been lowered, back to their upper or normal position and the spring 99 will snap the latch 98 into position to hold the stop 96 up.

This invention relates to printing machines and more particularly to perforated card controlled printing machines.
One of the objects of the invention is to devise a printing machine capable of operating at a very high rate of speed.
Another ob'ect is to devise mechanism for controlling the printing from perforated record cards in which the perforations in the card are in combinational arrangement and in which the mechanism is adapted to translate the combinational reading into its ultimate meaning at a high rate of speed.
Another object is to devise a high speed printing mechanism in which it is unnecessary to restore the printing elements to normal position after printing has been offected in one cycle and before printing in the next cycle.
Another object is to devise combinational translating mechanism which need not be restored to normal position before being set for controlling the printing mechanism in the next cycle.

Fig. 7 is a wiring diagram of the electrical control device shown in Fig. 6.
Fig. 8 is a table showing a rearrangement type wheel is normally rotating constantly to cause the successive type elements to pass through printing position. The perforated record card is fed under an electric brush which upon sensing a perforation in the card closes an electric circuit which in turn effects the setting of stop devices. These stop devices control setting of several combinational combs. The mechanism which effects the rotation of the type wheel carries a stop pawl which is controlled by the setting of the combs and stops the rotation of the type wheel in a position controlled by the set up of the combs. This brings the particular type on the wheel into stop position in line for printing. This takes place for each column or printing wheel. After all of the printing wheels have been set in position for printing they are then snapped against the platen which carries a sheet of paper to effect printing upon such sheet.
In Fig. 1, the type wheel 1 is shown as rotatably mounted on a carrying arm 2 and .is provided with a gear 3 fixed thereto. Gear 3 meshes with a pinion 4 rotatably mounted on the arm 2 and meshin with a gear 5 mounted on a shaft 6. ear 5 meshes with pinion 7 which in turn meshes with gear 8 carried on a shaft 9. There are as many gears 8 mounted on shaft 9 as there are columns of printing type or Wheels 1. Between the several gears 8 are friction washers 10. The washers may be connected to a shaft through a groove 11 so as to be free to move longitudinally on the shaft and constrained to rotate therewith. The gears 8 on the other hand are freely mounted on the shaft 9. Fixed on the shaft 9 is a gear 12 meshing with a ar 13 carried by a driving shaft 14. Sha 14 causes shaft 9 to rotate continuously'thus causing the washers 10 to also rotate continuousl The washers 10 are all pressed against t e gears 8 b a spring 10a and tend to turn the latter t us causing the type wheels 1 to rotate. Any of the gears 8 may be locked against rotation to stop the turning of the type wheel 1 to bring any of the type characters or elements 15 to a stop in the printing line.
Integral with the carrying arm 2 is a ringlike member 16 carrying several projecting pins 17 reaching through slots 18 in three combinational combs or rings 19, 20, 21. These combs have notches 22 arranged along their inner periphery and a pawl 23 (Figs. 1 and 4 ivotally mounted on the gear 5 is provi ed with a tooth 24 reaching across the inner peripheries of the three combs. As the gear 5 rotates the pawl 23 is carried around with the tooth 24 pressing against the inner peripheries of the combs 19, 20,
21. When the pawl reaches a position where three notches 22 in the combs are in alignment the tooth will be pressed into the notches. This will bring the opposite tooth 25 on the pawl into engagement with one of the teeth of a ratchet 26 fixed on the shaft 6 which does not rotate.
This in turn will-stop the type wheel and the train of driving gears 4, 5, 7 and 8 so that as the shaft 9 and washers 10 continue to rotate the particular gear 8 will be permitted to slip. The ring 16 is provided with a projection 27 having a spring 28 tending to turn it in a clockwise direction to rock the arm 2, thus moving the type wheel with the type 15 into cooperation with the platen 29. A rod 30 carried between arms 31 mounted on shaft 6 normally holds all of the arms 27 in the position of Fig. 1 thus holding the type wheels away from the platen. A link 32 is provided with a cam follower 33 cooperating with a cam 34 fixed on the drive shaft 14. Once during each cycle of operation a depression 340 in the cam permits the link 32 to drop. The spring 28 w1ll then snap the printing wheel against the platen to effect printing. Also freely mounted on the shaft 6 is a frame 35 carrying several sets of setting stops 36, 36a, 36b, 37, 37a, 37b, 38, 38a, 38b. The stop 36 is provided with a'spring 39 tending normally to move it to the right. An arm 40 on the stop 36 cooperates with pins 41 on the stops 36a and 36bto move the latter stops to the right also as viewed in Fig. 1. Stops 36a and 36b cooperate with latches 42 pivoted at 43 to the frame 35. A spring 44 connected between stop 3602 and the latch 42 tends to hold the latch in cooperation with a shoulder 45 on the stop 3611). Turning of the latch 42 counterclockwise releases the stop 360 thus permitting the spring 44 to move the stop to the left. This spring is stronger than sprin 39 and so moves the stop 36 to the left a so. Stop 36?) is similarly constructed and is also adapted when released to move the stop 36 to the left. Stop 360 may thus move to the left carrying stop 36 and leaving stop 36b in its normal position to the right, or the stop 366 may move to the left with stop 36 leaving stop 3601 in its normal position to the right. If neither stop 36a nor 36?) moves to the left then stop 36 also remains in its position to the right.
The combination combs 19, 20, 21 are provided with projections 1901, 200:, 21a. The projection 19a is adapted to cooperate with any of the stops 36, 36a, 36b. The projection 20a is ada ted to cooperate with stops 37 37a, 37b an the projection 21a is adapted to cooperate with stops 38, 38a, 38b.
'The frame 35 is connected to one or more links 46 provided with cam followers 47 cooperating with cams 48 carried by the driving shaft 14. Frame 35 is thus moved clockwise about shaft 6 a distance controlled by the cam 48 and then moves back to its normal position as in Fig. 1. As the frame moves upwardly, if stop 36 is in its outer position, it will enga e the projection 19a rocking the comb cloc wise around shaft 6. The distance through which stop 36 moves the .comb 19 may be designated as 3 steps. If, however, the stop 366 has been released by its latch 42, carrying stop 36 with it, then the stop 36a will engage the pro'ection 19a to rock the comb 19 two steps. If the stop 36a has moved to the left with the stop 36, then the stop 36b will engage projection 19a. and rock the comb 19 one step. If both stops 36a and 36b have moved to the left carrying stop 36 with them, then, the comb 19 will not be moved at all. In this case, the stop 37 will move into position to engage but not to move the pro ection 19a.
The projection 20a; is similarly controlled by the stops 37, 37a, 37b to set the comb 20. If stops 37a and 37 I) both move to the left with stop 37 then stop 38 will move into engagement with projection 20a without shifting the latter. Projection 21a is controlled in the same manner by stops 38, 3801, 386. A special stop 49 is provided to engage projection 21a when the stops 38, 38a, 38?) have all moved to the left. It should be noted here that the projections 19a, 20a, 21a are of different lengths which is also true of the sets of stops 36, 37, 38.
Thus, the stop 36 will not interfere with projections 210., 20a. Nor will the stop 37 interfere with projection 21a. On the other hand, if the stops 36, 36a, 36b have all moved to the left and stop 37 has also moved to the left, the latter stop will still be in position to engage projection 19a without moving the latter. In other words, when the stop 37 moves to the left so as not to effect a setting of projection 20a, it is still long enough to cooperate with rojection 19a.
The ring 16 is provided with a projection 50 on which is pivotally mounted a latching pawl 51 actuated by a spring 52 into cooperation with ratchet teeth 53 rovided on each of the combs 19, 20, 21. he pawl 51 prevents turning of the combs under the influence of their springs 54.
Integral with the frame 35 are arms 55 provided with a cross rod 56 adapted to engage a-projection 57 on the pawl 51. As the frame 35 reaches the limit of its upward movement the rod 56 engages all of the pawls 51 rocking them out of cooperation with the teeth 53. The reason for this is that one or more of the combs may have been set in a position during the previous cycle, a distance greater than it is to be set durin the current cycle and will have been locke in such position by the pawl 51. Thus, the stops 36, 37 or 38 will not on their upward stroke engage the projection on such comb to move the latter, but as the frame 35 approaches the end of its stroke, the rod 56 will move the latches 51 releasing all of the combs so that those that may then be in position beyond the reach of the stops 36a or 37b, for instance, Will now be released to be moved by their springs 54 into cooperation with such stops, thus receiving the proper setting for the curent cycle of operation.
As the frame 35 now commences to be lowered to its normal position, the rod 56 will release the latches 51 permitting them to engage in teeth 53 to hold all of the combs in their newly set positions. It is, of course, understood that the setting of the several combs under control of the stops 36, 37, 38 is a little beyond the actual operative position and the ratchet teeth 53 will at the same time be slightly beyond the latching position of pawls 51. Thus, as the rod 56 recedes and the pawls move into cooperation with the ratchet teeth 53 the parts will all come to rest in their proper operative positions. As frame 35 is lowered, projections 42a on the stops 36a, etc., will engage a cam edge 42?) on a member 420 and will be moved back to normal position and be relatched by latch 42.
The rod 56 is also adapted to engage an arm 58 pivoted at 59 and provided with a projection 60 adapted to cooperate with the teeth of gear 8 to stop their rotation. The stoppage of the gears 8 in this manner takes place just as the combs 19, 20, 21 are being set. This stops the travel of the pawl 23 so that it will not tend to drop into any of the notches 22 until the setting of the combs has been completed. When the setting is complete and the rod 56 begins to return to its normal position, it will release the arm 58 thus releasing all of the gears 8 to permit the parts to again rotate. The pawl 23 then will commence to travel in a clockwise direction until it finds a position in which notches 22 in the three combs are in alignment. At this point, the pawl will drop into the notches at one end and engage the ratchet teeth in wheel 26 at the other end. The engagement of the ratchet teeth 26causes the stoppin of the gear 5 and type wheel 1. After all 0 the type wheels hav been stopped in their several printing positions, then the bar 30 will be dropped to permit the springs 28 to snap the type wheels up against the platen to effect the printin The setting of the various stops 36, 3 38 is efiected under control of perforated record cards 61 which are fed one after another by feeding rollers 62, 63 which aredriven by pinions 64, 65. These pinions are driven by a gear 66 meshing with a pinion 67 on the driving shaft 14. The cards are fed downward y between a common contact roller 68 and a sensing brush 69. The roller 68 is electrically connected by a wire 70 to one side of an electromagnet 71. The other side of this magnet is connectedby wire 72 to one side of a source 73. The other side of this source is connected by a wire 74 to the sensing brush 69. The armature 75 of the magnet 71 carries a plunger 76 ada ted to reach into the path of theseveral latc ing members 42. The frame 35 is moved upwardly synchronously with'the feeding of the card under the sensing brushes 69. Each brush 69 cooperates with one column on the record card 61. Each column is divided into six index point positions according to the arrangement of Fig. 5. Perforations in various combinations in any particular column are adapted to represent various values. As each index point position is passing under the sensin brush 69 a corresponding one of the atches 42 will be approaching the plunger 76. 'If there is a perforation at the particular position in that column on the card the magnet 71 will be energized moving the plunger 76 into the path of theparticular latch 42. Thus, as the latch 42 passes the plunger 76, the latch will be rocked out of cooperation with the stop 36a or 36?), etc. As soon as one of the latches 42 has been set the plunger 76 is immediately restored to its normal position out of the way of the next latch 42 so as not to interfere with it. Now if a perforation appears at the next index point position in the column, the plunger 76 will be set again before the corresponding latch 42 reaches it so that such latch may be rocked. In this way, as a given column passes under the sensing brush 69 one or more of the latches 42 will be tripped depending upon the combination of perforations in that column.
The duration of energization of the magnet 71 is equal to the time that it takes for the perforation to pass under the brush 69. As soon as the brush rides out of the perforation breaking the circuit, the magnet becomes deenergized and a spring 77 will restore the armature and the p un er 76 to normal position. In order to e ect very rapid operation of the device an additional electromagnet 78 may be provided on the opposite side of the armature 75. One side of this magnet is connected to wire 72 while the other side is connected through wire 79 to a brush 80 cooperating wlth a commutator 81. Another brush 82 on this commutator is connected by wire 83 and wire 74 to the other side of the source. The commutator 81 is mounted on a shaft 84 on which is fixed a gear 85 meshing with a gear 86 on the driving shaft 14. The commutator is provided with six, contact segments 87 connected to a common contact strip 88. The brush 82 is constantly in contact with the strip 88 and the brush 80 is timed to engage each of the segments 87 just after the brush 69 has ridden out of a perforation in the card to break the circuit through magnet 71. The com- ,mutator 81 thus energizes the magnet 78 as soon as magnet 71 becomes deenergized. This will effect a quicker and more positive restoration of the plunger 76 than would otherwise be efi'ected by spring 77 alone. Thus, the plunger 76 after having tripped one of the latches 42 will be restored very rapidly and will thus permit a more ra id operation of the frame 35. While it as been said that the shaft 6 does not rotate, this shaft may be fixed to the arms 31. When these arms rock to cause the type to strike the platen, the ratchets 26 are rocked an equal distance. The pawls 51 carried by rin 16 cause the combs 19, 20, 21 to move a slmilar distance. Gears 5 are then permitted to turn an equal distance due to their constant tendency to turn and helped by the cooperation of the combs with pawl 23. Thus, when the type wheel moves against the platen, the corresponding movement of gear 5 makes it unnecessary for pinion 4 to roll on gear 5 and change the position of the type wheel.
In Fig. 6, I have shown a modification of the device in which six combs 89, 90, 91, 92, 93, 94 (see also Fig. 7) are employed. These combs are provided with projections 95 of different lengths reaching into the paths of movement of six stops 96 carried by a frame 97. The stops 96 are normally held in their upper osition by latches 98, springs 99 being provi ed to hold the latch in operative position. The frame 97 is connected through an arm or arms 100 to rocking arms 101 which in turn are connected by links 102 having cam followers 103 cooperating with cams 104 on the operating shaft 14. The frame 97 moves to the left synchronously with the feeding of the card 70'so that as each index point position on the card passes under the sensing brush 69, a corres onding one of the latches 98 will be approaciiing the plunger 76. Energization of magnet 71 will set the plunger 76 to rock the latch 98, releasing correspondin stop 96 which will be moved downwardly by the spring 99. Each of the stops 96 cooperates with a corresponding one of projections 95. When the frame 97 reaches the end of the stroke to the left those of the stops 96 that are in their upper position will engage their projections 95, moving the combs 89, etc., slightly to the left. At the same time the frame 97 will engage a link 105 rocking the latch 106 out of cooperation with the combs 89, etc.
\Vhenever a stop 96 has been lowered by reason of the setting of the plunger 76 corresponding to the perforation in the column on the card, a corresponding projection 95 will not be engaged by the plunger 96 so that when the latch 106 is lowered, it will release that particular comb to permit the latter to be moved to the right under whe action of its spring 107 until a stop projection 108 engages a stop bar 109.
The frame 97 starts back to its normal position to the right immediately, thus permitting the latch 106 to move back into cooperation with the combs 89, etc. Those combs which have not moved one step to the right will thus be relocked in their normal positions while those that have moved to the right will remain in such position. If any of the combs 89, etc., had moved to the right during the previous cycle they will not be restored until the stops 96 in the current cycle engage the projections 95 to move the combs to the left. Any combs thus restored will be latched in such position when the latch 106 moves upwardly. Combs 89, etc. are provided with notches 110. Three of the combs 89, 90, 91 cooperate with contact operating fingers 111 and the other three combs 92, 93, 94 cooperate with another set of contact operating fingers 112. Whereever three of the notches 110 in the combs 89, 90, 91 are in alignment, corresponding finger 111 will drop into the notches, thus closing contacts 113 and wherever the notches in the three combs 92, 93, 94 are in alignment a corresponding finger 112 will drop into the notches closing contacts 114. In this way, the various sets of contacts 113, 114 will be closed thus establishing a circuit through an electromagnet 115 at a time in the operation of the type wheel 1, depending upon which of the contacts 113, 114 are closed which in turn, of course, depends upon the particular arrangement of the perforations in the column on the record card 70. The contacts 113, 114 are variously connected to several commutator brushes 116. These brushes cooperate with commutator 117 mounted on the shaft 118 on which is also fixed a gear 119 meshing with the gear 5.
The fingers 111, 112 are provided with springs 120 tending to lower them into the notches 110. If a finger is in its lowered position in the notches, movement of one of the combs 89, etc., will cam the finger out of position to permit the corresponding contacts 113, 114 to open. After the combs have been set under control of the reading of the card and the contacts 113, 114 close to correspond to the perforations in a particular column, the rotation of commutator 117 will thereafter close the circuit through electromagnet 115 at a time depending upon which contacts 113, 114 have been closed. The commutator 117 is provided with contact segments 121 which are interconnected by a conducting ring 122. The segments 121 are located at varying distances apart on the periphery of the commutator. At a particular point in the rotation of the commutator, two of the segments 121 will be simultaneously engaged by the first and ninth brushes 116. If the setting of the combs has effected closure of the first and ninth set of contacts 113, 114 then when the first and ninth brushes 116 are in contact with segments 121 a circuit will be closed from the positive side of the line to the first set of contacts 114 then through wire 123 to the first brush 116 then through the segments 121 and ring 122 to the ninth brush 116, the ninth set of contacts 113, wire 124, magnet 115 and back to the other side of the line.
If a difierent set of contacts 113, 114 is closed then the completion of the circuit through magnet 115 will take place at adifferent time in the operation of the commutator 117 through different segments 117 and brushes 116. Thus circuits representing the difl'erent characters arranged according to Fig. 8 will take place at different times according to the combination of brushes 116 as indicated by the table in Fig. 9.
Here, it will be seen that the first and second of the brushes 116 will be interconnected through the segments 121, and ring 122 and at the next point in the cycle, the second and third of the brushes 116 will be in position to close the circuit through segments 121 and ring 1 22 to the magnet 115. The successive points in the cycle at which the several brushes 116 combine to close the circuit through the magnet 115 are shown by this table of Fig. 9. Thus the circuit through the magnet 115 is closed at a point in the cycle of operation of the machine depending upon the combination in which contacts 113, 114 are closed which in turn depends upon the reading taken from the control each combination of brushes 116 is intercon-- nected through the segments 121 the corresponding type character 15 will be arriving at the printing osition so that the closure of the circuit t rough the magnet 115 will stop the type wheel with the particular type character in position to print.
When the followers 33w drop into the depressed portion 340 of the cams the spring 28a will rock the type wheel into printing cooperation with the platen 29. It will be noted that when the gear 5 is stopped gear 119 and commutator 117 also stop. When these parts are later released for operation again, they are thus still in the same rela-. tive positions and the type elements 15 will continue to move in synchronism with the segments 121. Thus regardless of the position at which the type wheel is stopped in any cycle of operation or the position at will bring the proper type elements 15 to a stop in position for printing. After the combs 89, etc., have been set under control of the stops 96 the frame 97 will then commence to move back toward the right to the position of Fig. 6. The frame 97 will thus release the link permitting the latch 106 to cooperate with the combs to hold them in their set positions. A member 131 having a cam edge 132 is in position to be engaged by a projection 1.33 on each of the stop members 96 as the frame 97 moves toward the right. This will cam the stops 96 that may have been lowered, back to their upper or normal position and the spring 99 will snap the latch 98 into position to hold the stop 96 up.
When a particular set of brushes 116 break the circuit through the magn I Thus, when the closes a circuit through segmental contacts 121, magnet 115 is energized, attracting its armature 125 and releasing latch 126. The latch then snaps against the ratchet wheel 130 slightly. in advance of the next approaching tooth. When arm 27w rocks to effect printing the arm 127 lifts latch 126 slightly, thus permitting ratchet 130 and gear 5 to follow the swinging movement of the type wheel and the pinion 4 does not roll on gear 5 to shift the position of the t e wheel. All of these movements which ta e lace after the brushes close the circuit t rou h the segments 121 permit the segment w eel 117 to turn far enough to et 115 to release armature 125. latch pawl 126 is lifted by the arm 127 the armature 125 will snap into osition under the left end of pawl 126. T en when arm 27a is restored to normal position, lowering arm 127 with the pawl 126, the latter, being held up at its left end by armature 125, will be lowered at the point 128. This will remove the right end of the awl from the ratchet wheel. The parts wil now be in the positions of Fig. 6 and the type wheel and the segment wheel 117 will resume thelr turning.
It will be noted in Fig. 5 that the arrangement of the combinations of perforations to represent the several characters is in step by step progression. In Fig. 8, the
same combinations of perforations are employed to represent the various characters but they are scattered as will be seen. ThlS scattering is for the purpose of arranging the time of closure of the circuit throu h the various combinations of brushes 116 in the progressive order indicated in Fig. 9.
