order that, after a number has been set up in one column the pins representing said number will not be affected by the setting of pins to represent a number in another column. The repeat mechanism is also capable of use to enable repeated addition or listing of parallel columns 6f numbers.

In event of error or mistake in operating the numeral keys, and thereby setting up one 01'- more wrong digits, the pins which had been set to represent the digits of the number may be displaced and returned to their idle or initial positions before operating the adding or recording mechanisms. The incorrect number may thereby be canceled or dissipated or erased from the number setting mechanism before entering into the adding mechanism or into the recorded lists of items or numbers. The power required to operate the error correcting mechanism is slight and consists only of sufiicient power to set or position 0 pins in the rows corresponding to the pins which had been set by the number keys. The mere act of setting the 0 pins incidentally permits automatic return of digit pins which had been set by the number keys, and without any movement of the pins supporting frame which continues its stationary position.

It will appear from the appended description of the mechanism in detail that the means which operates incidentally to the operation of the numeral keys to set a pin in one row of corresponding value to a pin set in an adjacent row in a preceding operation, is automatic, and is actuated by a suitable motor device and escapement mechanism, so that there is no increase in the manual work as the value of the number increases, but the touch of the keys is constant and uniform throughout.

P Y At this point it.app'ears appropriate to mention thattherej is one, ro \v of pins 21, ,v' with which-11o; train. .of' adding er. recording mechanismncoiipetates, so. that thereri snonerl iov additional row of pins 21 in addition to a number of other rows, each of which other rows cooperates with a train of adding or recording mechanism. It is through the cooperation of this additional row with the keys and the levers 13 that the pins in the other rows may be set to represent numbers. The additional row of pins 21 with which no train of adding or recording mechanism cooperates, is indicated at X in Fig. 4.

In the normal or usual position of the carriage 9 the row of hammers 15 are immediately below the lower ends of the additional or extra row of pins, (Fig. 12), So that when any numeral key lever is operated a pin 21 of corresponding digital value will be raised in the extra or additional row of pins as a direct result of and immediately upon the depression of the numeral key. By means of cooperating devices the pin so positioned by the depression of the numeral key sets a pin of corresponding value in the adjacent row of pins with which a train of adding and recording mechanism cooperates, and subsequent operations of any of the numeral keys result in stepping the digits of the number from order to order by setting the necessary pins of corresponding value in the different orders until the entire number has been set up by the pins 21. It will be observed that the means for setting the pins of corresponding value in adjacentrows incidentally to subsequent operations of numeral keys is under control of pins of corresponding value set by a preceding operation of a key previously operated. It will be further observed that the field of pins does not move from order to order, but that the pins themselves control the order to order stepping mechanism, and that the stepping mechanism is automatic in its operation and takes place as an incidental result of the operation of the numeral keys.

Below the pin frame 16 is another frame which includes two side members 27, (Figs. 10, and 12), united by suitable tie-rods 28. The side members 27 have downwardly extendin arms, the arms at the rear being pivote to levers 29 which are supported upon a shaft 30 and the arms at the front being pivoted to levers 31 which are attached to a rock shaft 32. The ends of the levers 29 and 31 are connected by pin-and-slot connection 33, so that the adjacent ends of said levers move vertically in unison to raise and lower the frame 27, whenever the rock shaft 32 is rocked. The frame 27 is raised and lowered'as an incident to the operation of each numeral key through connections operated by a motor and escapement device which is under control of the numeral keys, and which I will now describe. A universal bar 34 (Figs. 4 and 6) extends across the upper ed es of the numeral key levers 2 rearwardly rom the shaft 4 upon which said levers are pivoted, and is attached to two arms 35 whose rear ends are attached to a rock shaft 36 which is mounted in suitable supporting brac'kets attached to the base of the machine. An escapement member 37 is attached to the rock shaft 36, and another escapement member 38 is pivoted upon said rock shaft 36 adjacent to the member 37, and is actuated toward said member 37 by a connecting spring 39, being limited in its movementby a promoting lug 40 on the member 37. An escapement ratchet wheel 41 is embraced between the escapement members 37 and 38. The wheel 41 is rigid upon-a hub or bushing 42 mounted upon a shaft 43. The said escapement ratchet 41 is also in rigid connection with a motor-spring drum or casing 44. A motorspring 45 is inclosed within the drum or casing 44 and has one end attached to said drum or casing and the opposite end attached to a sleeve 46 which is mounted on the shaft 43' (Fig; 7). Assuming that'power is stored in the spring 45 it is clear that, when anumeral. key is operated the escapement ratchet 41 will escape between the escapement members 37-38, being actuated by the power in the spring 45. A cam disk 47 is attached upon the hub or bushing 42 and is, therefore, rotated in unison with the escapement ratchet 41. The cam disk 47 is formed with a number of cam projections upon its periphery, there being one of said cam projections for each tooth or step-space through which the escapement pinion or ratchet 41 moves-when operated as aforesaid. The cam disk 47 operates upon a small roller 48 which is supported upon a stud or pin on the front end of a lever 49 attached to the rock shaft 32. From the foregoing it is obvious that rotation of the cam disk 47, through the operation of the escapement and motor device, rocks the' shaft 32 as a result ofeach depression of each numeral key and thereby raises the levers 29 and 31, which, in turn, raise the fra-me 27. Springs 50 (Figs, 2 and 3) are effective to restore the levers 29 and 31 and the other parts directly movable therewith to their idle or normal positions. The frame 16 supports a plate 51 at each end, each of said plates being provided with a series of vertical slots 51, which correspond in number and relative position to the rows of pins 21. A number of plates 52 (Figs. 2 and 11) have their ends extending through the slots 51 at opposite ends of the frame 16. There is oneof these plates 52 for'ea-ch row of pins 21, and said platesare positioned adjacent to the lower ends of the pins. Each plate 52 supports a series of pawls 53. A suitable form and arrangement of the pawls 53 is illustrated in Fig. 11, in which the pawls are shown as extending above and below the plates 52, and the pawls of each series are order.

Each pin 21 is for'medwi'th an ob ique shoulderso'which rubs" against thecontacting pin 54 when said pin 21' is raised, thereby rocking thepawl 5'3 against'the tension of its spring'55 and positioning a pin '57'Zat the upper end of-said pawl 53in a notch or seat 58 of the pin '2l 'of corresponding Value in the adjacent row. "Thereis'onefserie'sof pawls 53 fo'r"eachnumerical'frdw or' order of pins 21, so that when a" 'in'21 in'any row is raised said pin 21 sets the corresponding pawl 53 in engagement with the adjacent pin 21 of correspondihgyalue; 'Th'e notches or seats 58 in which the'pin's'fii become 'e'ngaged as aforesaid, constitute latches to retain the pawls' '53; the latching engagement being effected'by a slight upward and downward movement of't he p'i'n 2'1"'s0 engaged in order to 'seatth'e pin 57" within" the notch'58.

From the foregoing it'will'be understood that depr'ession"of any numeralkey first sets a pin 21 of correspondingyalue the additional row of pins indicated "by X. 'The -motor and escapement device which operate as an incident to the operation of a numeral key, rocks the shaft "32"'as"previ ously described and raises the-basket or frame'27. As above explained the pin 21 inthe row X, which isset by the numeral key, engages a pawl 53 with a pin 21 of corresponding value in the next adjacent row "which, in this instance, is units row. Therefore, when the basket or frame 27 is raised the plates '52 will also be raised, and the pawl 53 which had been adjusted inengageme'nt with one of the pins 21, will raise'sa'id pin 21 until the said pin 21' is latched upon the corresponding latch pin 24:. The "frame or basket27 supports two plates 59 which are longitudinally movable in slots 60 in the sides of said frame or basket. The ends of the plates 52 project-through the slots 51 and over the lates 59 so that when thebasket 27 is raised y operation of the motor device the plates 52 will also be raised and thereby control the pins 21. The plates 59 are pivotally connected to the carriage 9, and are moved in unison with said carriage to perform certain classes of work as hereinafter explained. Whenthe pin in units row is raised in this mannersaid pin also positioiis'a pawl 53 of corresponding value so that subsequent operation of a numeral key will cause the motor to operate and permit movement of a pin in tens row of corresponding value to the previously positioned pin in units row, and this operation will be maintaincdthroughout the series of rowan-spins asthe numeral; ke s are operated; When'a' pin '21"i'n any'r'ow is "rais d after another pin in that row has been "raised, the adjustment of the second pin -moves the plate 23 'sojth'at the previously set pin will be res'tored' to its idleposition by -'its spring 22,- In the machine illustrated the type-car'- heist; arearcuate in" form and are suspended from a shaft- 62 Figs. 2' and 3) "11s The type-carriers 'areassociated with racks 63 which are also suspended from the'shaft 162i and which have pin-and-slot connection 64 with the type-carriers. "The'raeksare --connectedwithrearwardly extended'arms of the type-carriers by sprin' '65 which con- 'sti'tut'e an -"elastic' connection between the type-carriers and racks.

arranged" to operate withinthe channels formed bythe guides '20 and to engagerin pins 21' which may ha e' been set up to'repr'esent numbers as hereinbefore explained. The engagementi'of the heels 72 with-the pins 21 stops the'movement of the type-carriers andfracks and 'a'lines the printing type 73 adjacentto the printing hne of paper, .supported'upona platen 74. Printing'is efl'ected by the action of the type-driving hammers 75, through connections operated incidentally to the operation of thetyp'ecarriers, and substantially in the manner described in the Hopkins patent aforesaid. After the numbers aretprinted the type car- 'riers and racks are returned'to idle position by the rod 69 which is moved rearw'ardly by the return rocking movement of the'shaft 66 which is effected automatically 'by ower springs 76. The usual adding wheels 7 are controlled and operated 'by" the racks 6:3 efiectively to add the numbers listed for printed, in the well understood manner,-s1 1bstantially as described in the 'Hop'kms patent.

- After the number has been recorded 'by downwardly by springs 91.

the operation of the type-carriers and typedriving hammers the pins 21 which had been set to represent the number recorded may be automatically returned to their idle or initial positions, or may be retained inpo- 'sition to represent the number to be repeated, as in multiplication, forginstanc'e. An arm 78, (Figs. 3 and 18), is attached on the rock-shaft 66, and has a pin 79 extending under a link 80. The rear end of the link 80'is connected to a lever 81, which is supported by a shaft 82". The link 80 is actuated toward the side of the'a'rmi7-8 by a spring-83 connecting the lever 81 and link 80.. The lever 81 has a-rearwardly extend ing arm to which is pivoted a, link Be and which is supported by pins 85, (Fig, 14), on the rear standards 17, said pins 85 passingthrough slots.- 86 in said link. The link 84 is provided with two arms 87 having inelined'or oblique upper edges adapted to operate against rollers 88 on a vertically mov able member '89 supported by and having pin-and-slot connection 90 with the rear standards 17. The'member 89 'is'a'ctuated Two arms 92 attached -.toa rock shaft 174 extend under said--member 89; The member 89 extends transversely under the lower ends of the rear transverse row of pins '21. The rear transverse row of said pins 21, as previously explained, corr'espond'to the numeral character 0. When said member 89 is raised by the lateral movement of the cam members 87, Or otherwise, said member 89 will raise all of the 0 pins '21, that is, all of the pins 21 in the rear transverse row, and simultaneously release and enable the remaining pins 21 to be pressed downwardly by their springs 22. It will be understood that this operation .is effected by movement of the link 80, and I- will now describe the device for operating the said link 80 as an incident to the recording or adding ofa number, so that the pins 21 which had been set-to represent said numbers will be automatically restored to idle position, thereby clearing the pin frame. A pawl'91, (Figs.

-3 and 18), is pivoted upon the link 80 and has a hook 95 on its forward end in position to be engaged by the pin 79. A spring 96 yieldingly holds the hook 94 upon the pin 79. The arrangement is such that, after the heels 72 have engaged the proper pins 21 which had been set to represent the number to be added, the pin 79 will have moved the connections including the link-80, lever 81, and link 84, and the other parts actuated'by said link 84, a sufficient distance to raise the member 89 effectively to raise the 0 pins 21, and thereby permit the remaining pins to be pressed downwardly by their springs 22.

The pins 21 representing the number with which the heels 72 had been engaged in the adding or recording operation, are thus rethe type-carriers. A lever 98 which extends above and below said rock shaft is attached to one end of said shaft, and an'arm 99 corresponding to the upper portion of said lever is attached to the opposite end of said shaft, and a rod 100 is attached between the upper ends of said arm and lever. For each of the typecarriers there is a corresponding pawl 101 mounted upon the shaft 97 and having their lower ends normally above and out of contact with the upper edges or the type-carriers. Each type-carrier is formed with ten projecting teeth 102, (Figs. 2 and 3 eorres ondin in en a 'emcnt to the en- 3 a t: a gagement of the type and to the arrange- ,ment' of the pins 2-1, so that, as in each nu- .merical row of pins 21 there is one pin for each of the ten numeral characters, and, as in the case'of the type 73 there is one type on each type-carrier for each of the ten numeral characters; so, in the case of the teeth 102, there are ten teeth on each typeearrier, being one for each of the ten numeral characters or figures.

The upper end of each of the pawis 101 engages in front of the rod 100, so that, in one position of said rod 100, all of the pawls will be held out of engagement with the type-carriers; whereas, in another adjust ment of said rod 100 all of the pawls will become engaged with the type-carriers, said pawls being actuated toward the type-carriers by springs 103. The rod-100 has detent springs 104: connected thereto and in idle position of the machine engaged in front of projections 10.3 effectively to hold the rod 100 in position to prevent engagement of the pawls 101 with the type-carriers Movement of the rod 100 to engage the detent springs 10% behind the projections 105 permits the'pawls 101 to engage the teeth 102 on the type-carriers, and. this adjustment is automatically effected before the pins 21, representing the number being re corded and added. are restored to idle position.
