COMBINED TYIPEJWRITING- AND COMPUTING MACHINE.

- Patented Apr. 23, 1918.

Application filed September 23, 1913. Serial 109791264.

have invented certain new and useful lmpjrovements in Combined Type-Writing and omputing Machines, of which the following is a specification.

This invention relates to an improvement in combined typewriting and computing machines of the Underwood-Hanson type and is an improvement on applications of Frederick A. Hart, Nos. 36,836 and 466,837, filed December 10, 1908 (or the latters substitute igdfiontinuation, No. 838,930, filed May 16,

One of the objects of this invention is to economize space, or to provide a greater number of computing heads or totalizers for a. given space. For example, in the form of the invention illustrated, the advantage of four computing heads or totalizers is afforded, where only three might otherwise be used.

Heretofore it has usually been necessary on a typewriter to devote a separate computing head to each column, whether the column is wide or narrow; and where there is only room for three computing heads in the machine, it makes it impossible to print more than three narrow columns on a sheet, whereas it is sometimes desired to print tour or five narrow columns, and at other times to print only three wide columns, on the same machine.

This invention increasesthe capacity of the machine, by making it possible to use two totalizers, either for two wide columns, or for four narrow columns, or for one wide column and two narrow columns, as may be desired; at the same time the amounts written in all columns may be accumulated upon the grand total computing head.

This may be stated in another way by sayingv that there is a need of sometimes using small and sometimes large numbers in ditlerent columns, to fill which need small computing heads or totalizers are provided where small numbers are to be computed, and large computing heads provided where large numbers are to be computed: and there is also provided a gross computing head to act simultaneously with the others and therefore compute both large and small .as to be plainly visible.

numbers, so as to obtain a gross total. There may be provided one or more computing heads of a capacity of 9,999,999.99. There may also be provided two or more other computing heads limited to smaller numbers, such. as 999.99 and 99.99. Further, there may be provided a gross computing head capable of computing 9,999,999.99, to run up the gross total of all the numbers added in the first three or more computing heads.

This is, then, the problem that presents itself, how to preserve all of the old advantages, to use the adding'head for writing and adding wide columns when desired, and at the same time adapt it so that two narrow columns could bewritten and added on the work-sheet in the place usually occupied by each wide column.

In this type of machine, the numeral keys cause the types to print and also set up the number by means of index-pins. Subsequently a general operator advances the bars which bear the set pins, and turn the number wheels accordingly. The computing wheels are quite large and wide spread so They therefore occupy a space considerably greater than the same number of accordant letter spaces as typewritten to form a record of the digits of the numbers computed. In order to have a compact machine then, the number of computing wheels in all is limited, or. in other words, the number of major totalizers is limited. But by splitting or dividing the major totalizer into smaller or minor totalizers to correspond with the narrow columns-of small numbers computed. a greater capacity for a given space than has heretofore been available is made use of. a

The index-pins are mounted on denominational bars which are raised seriatim. so that when a numeral key is struck, the corresponding index-pin will be set on the particular bar which at the time is raised above its fellows. The bars are raised by means of a tappct carried by the ty 'iewriter carriage. The carriage travels from right to left. and the computing passes from left to right in the computing heads; the necessary inversion for raising the proper bars being accomplished through transposition linkages, which are operated by the lappots on the carriage.

Heretoforo when using a tappet or dog on ill) ' sary for'thetappet or dog to operate every one of the jacks in the computing head, and

thereby displace every one of the index-pin bars. This would occur during the progress of the carriage, even if only a narrow column were bein written on a page. It is necessary that t e carriage shall have traveled a certain distance carrying one tappetclear of a set of jacks before another tappet can'engage its corresponding set of jacks to index digits for the following column. By this improvement, the necessar lateral movement of the tappets and thus t e necessary travel of the carriage required for indexing in a plurality of columns, are reduced. This improvement also has special application even where no tandem or simultaneous computation is done, as. in simple cross addition.

In limiting the lateral movement of the tappets and in concentrating the computing range, the effective paths of travel of the tappets must necessarily overlap each other, so that the several tappets may not only pass through the range of their own associated jacks which they are designed to operate, but also pass by the jacks corresponding'to'other tappets and whichit is not desired to have them operate.

In order to avoid the contingency of the several tappets operating jacks belonging to other computing heads than those for which the particular tappets are set, the tappets are made of'difierent effective lengths and are provided with pawls or dogs located at different points along their lengths with respect to the pawls or dogs on the other tappets. These dogs or pawls are then so located that they will come into engagement solely with" 'acks which they are designed to operate. 0 do this, the 'acks themselves must be of different effective lengths. That is to say, each computing head or section of a computing head, where a computing head is divided into a' plurality of minor totalizers, is provided with a set of jacks of a length and form designed to be actuated solely by the accordant tappet or tappets. In other words, suppose that there are computing heads A, B and C, B the head being divided into a plurality of minor computing heads or totalizers to be designated as B and B, then thecomputing head A will have a series of jacks of a certain form and length, which will be actuable solely by a tappet of a corresponding effective length. The sections or minor totalizersB and B being arranged right alongside each other, may be operated successively by a single tappet, the two sets of jacks and the tappet bein of cooperating lengths. The lengths 0? these jacks, however, may be such that the tappet which operates them, will, when it comes into the range of the first set of jacks corre sponding to the computing head A, slip idly past the same without the dog or pawl thereon coming into engagement with these jacks.

For the last computing head, that is, the head C, the jacksmay be arrangedso that they may be operated concomitantly with those of the computing head A, and also concomitantly with those of the two minor computing heads B and B whereby the computing head C may be used as a ross totalizer. That is to say, the jacks 0 this last computing head may be designed to permit the indexing of large numbers at the same time that such numbers are computed in the large computing head A, and also index two sets of small numbersat the same time that such numbers are computed in the two minor totalizers or computin heads B and B To do this, the jacks o this computing head C are arranged in two sections. All of the jacks have an effective length such that a single tappet of right length with the dog or pawl thereon properly positioned, may actuate all of them to correspond with the actuation of all of the jacks located so as to operate the extended jacks i corresponding to the four digits of lowest denomination. This latter type of tappet will actuate these jacks of lower denomination at the same time that the jacks of the minor totalizers B and B are actuated, so as to enable the computin head C to compute concomitantly with t e minor computing heads B and. B. y

Inasmuch as the computing heads B and B operate successively, there will be provided two tappets capable of actuating the four digit jacks of lower denomination, and these tappets will come into play successively corresponding to the activity of the two minor computing heads B and B The tappet which operates the two sets of jacks corresponding to the minor computing heads B and B, has its dog so located thereon that it will escape past all of the jacks of the totalizer C. On the other hand, the tappet which actuates all of the jacks of the totalizer C, has its dog located at such a point that it will escape all of the jacks of both the minor totalizers B and B It will be understood that while in this example only one large totalizer and two -21 ill diiierent lengths, so x. 1w 1 q on area "by oiii'erent tappets placed whereby the order of small totalizers are used in connection with a gross totalizer, the number of totahzers ma be varied to suit the character of work to e done, either by adding others or by dropping some of those described.

Other features and advantages will hereinafter appear.

I

Fig. 4c is a view similar to Fig. 3, with the exception that the carriage has traveled farther along and the first jack of the first minor computing head is being actuated at the same time that the jack corresponding to tens is being actuated in-the gross or cross totalizer.

Fig. 5 is a diagrammatic view similar to Figs. 3 and 4, with the exception that the carriage has traveled still fartheralong and is in the act" of bringing a air of tappets into cooperation one with t e firstjack of the second minortotalizer, and'the other with the jack corresponding to tens in the gross or crosstotalizen.

Numeral keys 1 and al press key levers 3 to me swin type-bars 5 the ront side of a platen 6 mounted on sprin -driven carriage 7. The latter travels y step, controlled by an escapement mechanism 8. A rack 9 on carriage 7 engages a pinion 10 connected to an escapement wheel 11, which is controlled by dogs 12, rocked by a universal frame 13, which from heels 14: carried by habet keys 2 de bell cranks 4 to type-bars 5.

up rearwardly against The numeral keys 1 not only write the numbers on the work-sheet carried by the platen '6, butalso depress links 15 to en age arms 16 and rock shafts'li carrying t ese arms. These rock shafts 17 each actuate a transverse linkage 18 to depress or set index-pins 19. These index-pins are mounted on denominational bars 20, each bar carrying nine, to correspond withthe numeral keys. The pins extend in transverse rows corresponding to the linkages 18, so that when any one of the bars .20 is in elevated position at the time that a numeral key 1 is struck, the correspondin linka e depresses the subjacent in 19 out e raise bar, which afterward fa s. The set pins compose a number, to predetermine the extent of longitudinal movement 0 the bars 20. It will benoted in passin that the number wheels of the computing ead are wide-spread and large, and occupy in theaggregate a denominational area considerably greater in extent than the jacks 3%. This means that the number wheels extend over a linear distance considerably greater than the corresponding number of letter spaces of according denominations as written on the work-sheet. This gives room for the actuating mechanism for the out her wheels, and also permits the latreadiiy visible and to have compara- Y inscribed on their pes racks on the r nicn clog cent e purpose the depressed y cross ber on gentheir enois on lilo , tend forwardly which willbe calle a rod 35 and at their rear ends arranged to de ress thrust links 36.

' ach ofthe thrust links 36 is arranged to rock a bell crank 37, which in turn enga es a downwardly-extending finger 38 on a llnk 39. Each of the links 39 has a parallel in a link 40, which is connected thereto at both ends by means of pivotally-mounted bell cranks 41 and 42. The links 39 are provided with upstanding fingers 43 beneath the index-pin bars 20, to raise the same one at a time. The bell cranks 37 are graded in length to engage the fingers 38, which are arranged in echelon on the links 39 and extend orwardly from right to left. The fingers 43 are also arranged in echelon but exfrom left to ri ht. This transposition llnka e mechanism inverts the order of action of t e jacks 34 upron the bars 20, which are operated in order om highest to lowest denominations.

At Fig. 1 there are seen three computing heads or totalizers A, B and C with their dial wheels 25. There is a set of the indexp1n bars '20 for each of the computing heads A, B and C, and the key-operated linkages 18 extend across all of these three sets of pin bars, so as to be capable of setting pins on any of them, or on two or more bars simultaneously, in the several sets." The middle-com uting head or totalizer B 1s a twin totalizer, eing com osed of two minor computing heads operab e independently of each other. One of these two minor computing heads or totalizers has a capacity of 999.99, and the other of 99.99.

We have, in efiect, four totalizers: A which will be called the major totalizer and which has a capacit of nine digits; B, which will be called t e first minor totalizer and which has a ca acity of five digits; B,

d the second minor totalizer and which has a capacity of four digits; and C, which will be called the totalizer and which has a capacity of nine digits. The gross totalizer C performs cross-ccmpus tatlon, and 13 arranged to accumulate not only those numbers that are carried into the major totalizer A, but also individually the numbers that are carried into both the two minor totalizers B and B'.

The Lacks 34 in each set are of equal length, ut ofdiiferent length from those in the other sets, and the dogs 33' on the tappets 32 are accordingly laced some forwardly and some backwardly, or in difi'erent transverse vertical planes, so that each dog may actuate solely/ the jacks which it tended to actuate.

The tappets 32 are then of severalkinds' 32A designates the tappet which controls the jacksoftotalizer A.

32AC is the tappet which controls all of the jacks of the gross totalizer 0, whenever tappet 32A is engaged with jacks34A."

totalizers B and 32B C is the tappet which controls the set of jacks corresponding to the digits of lowest denominations associated with the gross totalizer C, whenever tappet 32B enga ed with jacks 34B 32 G is the tappet which controls the same lowest denomination jacks of totalizer C, whenever tappet 32B is engaged with jacks 34B.

The jacks 34 then are of different lengths,

to correspond to the positioning of the dogs 33 which actuate them and are indicated with numbers corresponding thereto, to wit: 34A, 34B, 34B, 34AC (w ich last applies to all of the jacks of thegross totalizer C), and 34ABB which applies to the jacks corresponding to the four lowest digits of the gross totalizer C.-

It will be seen by reference to Fi 1, 3 and 6, that one grou of the jacks 34 C corresponding to the our highest digits, are the shortest and can only be actuated by that tappet 32AC which has the rearmost do 33, because their teeth are set too far aclr to be engaged by any other tappet.

The next lon est jacks are those deslgnatedjas 34AB l which form a portion of the same major group 34AC and correspond with the four lowest digits of the totalizer {0; By reference-to Fig. 6, it will be seen that these jacks have teeth 49, whereb they are 0 rated. These teeth are of su cient bread tli to enable them to be engaged either by the dog on tappet 32AC, or b the do on tappets 32B O and 32BG. This set of Jacks 34AB B may one of these three dolgs.

The jacks 34A (be ongin to totalizer A) conform to the jacks 34A B, except thatthe teteth bthereof grehtog narrowhto be or;

The 'acks 34 34B are the longest of have narrow teeth 51 so placed as therefore be operated by any to engfige solely with the dogs on the tappet 32 Therefore the proper jacks onl will be actuated at the pro r time,"to determinedby the--travef of the carnage, and

each dog will avoid all jacks except those which it is intended to actuate; so that, in

effect, there are provided four computing heads or totalizers in a s ace usually occupied by three, with one o the totahzers actmg as a gross totalizer for all the remainthree totalizilalrsd h 82A, -t e evice t etappets 82B'G are first adjusted havebeen indexed by a setting" oiE where ta pet 32A engages the jack 34A of highest enomination (Figs. 3 and 8), that is, the first jack at the right of the group. At the same time tappet 32AC engages jack MAC of highest denomination.

Upon now striking the numeral keys 1,. the carriage 7 will move step by step in letter-feedin g direction, so that tap at 32A will rock jacks 34Asuccessively, an the tappet 32AC will rock the jacks 34AC accordingly. This causes the raisin serz'at-im of the index-pin bars 20 for 0th the computing heads A and C simultaneously, so that the index-pins in two of the groups will be set by the key-actuated linkages 18.

The general operator can then be actuated by means of the handle 30, so that the numbers already written on the work-sheet will be run up in the computing heads A and C simultaneously, the head A acting as a column totalizer, and the head 0 acting as a gross totalizer. (During the writing of the remainder of the line, tappet 32A will be out of use and nothing Wlll happen to totalizer'A.)

The carriage 7 will be advanced, as by means of a tabulating mechanism, not shown, until the next computing zone or column is reached. The tappet'32B now comes into engagement with the highest denomination jack of the series 34B (Fi t vand 9). At the same time, tappet 39 C enga es the highest of the set of jacks 34A 13 which connect to the first minor totaliaer B With the writing of the digits of the number to be accumulated, which number will be limited to 99.99, the carria e 7 will travel step by step concomitant y actuating the jacks 348 and Set-ABBh so that the number may be set up or in dexed on the pin-bearing rack bars 2d of the cross totaliaer C the first totaiiaer hen these small nunio er play. Under tn ss c with the tappet 32B cooperatin with the jacks 3413 and the tappet 32B cooperating with the jacks 34AB B The jacks 34=AB B can then be concomitantl actuated with the actuation-of thejacks 34 so that the numbers will be set up on the pin-bearinf; denominational bars for both the tota lzers B and C. After setting up, the handle 30 can again be actuated to run up these numbers in the second minor totalizer B and the crossor gross totalizer C. The carriage may then be returned and the same operation repeated for the next line. I

Taking up a specific example, suppose the it following numbers are to be summed up vertically in their columns and also the gross total of the several columns obtained:

Then the carriage 7 is started at its extreme right position and brought to the first computing zone or column by the tabulating mechanism, or otherwise, so that the tappet 32A will come into register with the jack 34A of highest denomination in the set corresponding to the totalizer A. At the same time the tappet 32AO will come into register with the jack MAC of highest denomination in the set corresponding to the totalizer C. See Figs. 3 and -8. he denominational bar 20 of highest denomination for both the totalizers A and G will then be raised so that as the numeral key.

5.is struck to rint and set up the digit 5 (being the 'igit of highest denomination in the first number to be computed), then the 5 pin will be set up on two denominational bars 20, one for the totaiizer A and the other for the totalizer The carriage T( will then move a letmr space, s

that the next two denominational bars, one

for the totaiizer A and the other for the totalizzer C, will be raised so that the 6 pin thereon can be set by a striking ot the key 6. This is continued tor the e digits (5",8t2i2l) of the numher, the spaces for the comma and decimal point between @1955? and 8 8 drnd 53 he care of I; he M Us A m3 E a. 3 i {/3 seen-n tn. in on the acns ric corresponding to the fourth digit column from the lowest in the totalizer 0. (See Figs. 4 and 9.) The mechanism is then in a condition to set up the number 67.65, so that it may be later accumulated in both the totalizer B and the gross totalizer C, the tappet- 32B C having escaped the jacks of highest denomination of the group 34AC, so that the digits will be properly set up in the gross totalizer C.

At this oint there will, be a denomina tional pin-bearing bar 20 connected to the fourth from the lowest computing wheel raised, not only in the minor totalizer B but also in the gross totalizer C, so that at the striking of the numeral key 6, the6 %in will be set up for both the totalizers and C. The carriage is then moved a letter space to set up thenumber 7 for both the totalizers B and C, and so on until the whole number 67.65 is set up, when the general operator can be actuated to carrythis number not onl into the totalizer B but also into the totallzer C. The totalizer B not having accumulated any number previously, will merely show the number 67.65, While the totalizer C, having already accumulated the number 567,843.21, will show the addition of the number 67.65 thereto, which will be 567,910.86.

The carriage 7 is then spaced again to bring into play the second minor totalizer Bto accumulate the number 35.34. When this occurs, the tappet 32B will have ad-- 'vanced to a point such that it will come into engagement with the jack of highest denomination of the set 34B. At the same time the tappet'32BC will have reached the jack of highest denomination of the second section 34AB B of the series of slacks 34AC corresponding to the totalizer (see Figs. 5 and 10). The number 35.34 will then be set up, not only for the totalizer B, but also for the totalizer C, andthat, too, with the digits in the proper denominational columns. This number can then be carried simultaneously into the totalizers B and C, so that the toi so ' tively.

talizer B will exhibit the number 35.34,

while the 'totalizer G will add this number to the sumof the first two numbers alread accumulated, givin the sum of 567,946.20 which-will be exh1 ited in this gross tota izer. The carriage may be then returned and the platen 6 line-spaced to start the .writing and computing of the second line of numbers.

As in the case of the first line, the tappets 32A and 32AC will'come into play simultaneously to control all of the jacks 34A'and 34AC of the totalizers A and C,

. 534,621.81, will then be set up simultane'ouslyfor both the totalizers A and C, and

can be run u into thesetotalizers by an ac-' tuation of 0 general operator, so thet in 32B can be The first number in the 8800]}(1 Ea,

the caseof the totalizer A, this number will be added to the number 567,843.21, 'ving the sum, 1,102,465.02, while the sai number will be added to the gross total, 567,946.20, already accumulated in the totalizer C, so that this gross totalizerflwill now exhibit the number 1,102,568.01.

The carriage 7 is then spaced to come to the second computing zone or column where the number 65.76 can be set u simultaneously for the totalizers B and and can be carried into these totalizers so that the totalizer B will exhibit the number 133.41, representing the sum of the numbers 67.65 and 65.76, while the totalizer C will exhibit the gross total so far obtained by the adding of the number 65.76 to that already accumulated, or, in other words, will exhibit the number 1,102,633.77.

The carriage is again sgaced to brin into play the minor totalizer number 25.42 to' the number 35.34 already accumulated therein. The number 25.42 will also-be set u and carried into the gross totalizer C simu taneously with its accumulation in the minor totalizer B. The minor totalizer B will then exhibit the num ber 60.76, while the gross totalizer C will exhibit the number 1,102,659.19.

We will have then at the finish the individual sums of the vertical columns exhibited in the totalizers A, B and B, the first being for a lar e number and the last two for smaller num rs.- We will, also have the gross total of all of the numbers, both large soastoa dthe' and small, exhibited in the totalizer O. This action can be continued for any number of 11 may be used. .In this adaptation of the invention, the jacks 34B and 34B com sponding to the minor totalizers B and B, respectively, are made of difierent lengths, so that they can be 0 rated by two difierent tappets 32B and 32 and not by the same tappet-as in the case of the form shown in F1? 1 to 10, inclusive. In the form shown in igs. 1 to 10, inclusive, the two minor totalizers were nly brought into play in succession, as the tappet 32B first actuated the set of jacks 34B and then actuated the second set of jacks 34B. 'In this modified form, however the tappets 32B and la along the rod 1, so that the minor totalizers B1 and B' to which they correspond, can be brought into lay at any desired points in the travel of e carriage; it not be" necessary that they shall come into play m direct succession. It will thus be seen that in this form, the com 'uting columns of small numbers can be wi ely separated if desired.

at any desired points? The tappets 32B and 32B of course are arranged to avoid the jacks 34A and 34AC of the other totalizers.

It has thus been shown how we may add three different columns one with large numbers and two with smal numbers, and accumulate both the large and the small numbers in the gross totalizer C, so that at the end of the operation we will have three column totals and a gross total; this also with a mechanism occupying a space normally occupied by but three totalizers. Of course it is to be understood that the number of totalizers is not limited to the number shown in this embodiment; more major totalizers or more minor totalizers might be used. On the other hand, the major totalizer A or one of the minor totalizers B or B mi ht be omitted. The invention is also appicable even it the gross totalizer C were om tted.

Variations may be resorted to within the scope of the invention, and, portions of the improvements may be used without others.
