Be itknownthat. I, RAFFAELLO LA PEGN subject of the King of Italy, residing ,at

Milan, Italy, have invented certainnew and useful Improvements in Typewriters, of

a'lYlllclltlle following iseo specification.

The present invention relates to type writers and has for its object a typewriter single key.

The typewriter .accordi ng to this invention is particularly useful in connection with bookkeeping, in which i-,t;is oftennecessary-;to writeja given numeral, figure or 'WOlCl in twoor morevcolumns -,or rows of a page.

The typewriter ,according to this ,vinventioncomprises a :frame, a carr agetravel- ,ling on said frame and carrying a book or a vpri1 1tin,g ;,mechanis n each of which aetuates {a ,type :for its ,prin-ting,.means for coupling togetherin. operationlvanyt desired number- 01" said sets and means foroperating thecoupledlsets (to obtain vthe impression ,of any. desired type in all said selected sets at the same timebythe manipulationof aisingle operating key.

fOn the annexed drawings is shown by waylof example anembodiment of amulitipletypewriter accordingtothis invention; and iii-the figures the typewriter 1s: assumed to be intended to write numeralslor,figures,

butof courseany desired characters or; signs maybe used in thekeyboard.

In said drawings: Figure 1 is the plan View of a typewriteraccordingIto this inin which the several printing mechanisms are provided with mechanical controlling parts; Figure 2 is a section to an. enlargedscale on the line .22 of Figure ;1; Figure 3 is theplan view to .anenlarged scale of a separate printing set; Figure 4; ,is a perspective view of \a device for connectingin'operation the several desiredtype sets; Figure 5 is a perspective view otthe end portion of the :carriage showing :the member intended to release vthe several printing mechanisms after thecarriage has completeda line of writing.

In the construct-ion shownby figures l, 2 andfi, 1 tea frame'or, support oniwhich are in the positio illustrated unounted ,a nnmloerof type sets, each set being. designated as a :whole ,bya reference ,1, 11,111, IV, and it isassumedthatthe apparatus comprises .five sets butof course .the number of .these sets may be .any .de- -ts ire;d.one; said :sets being hereinafter particularly described and ;the several meclia- .nisms oteach setare adapted to strike-the respectivetypes fibril common,printingpoint shown on :the .7 drawing ,by the reference '2.

Said type sets, which-niaylbein any-desired-number, as above stated, are located at a desired distance from eachother, each of them. being ,in position towrite on ;a;desired ;;point of the printingisurface which maybe a paper sheet, a book page or thelike. At (one side :ottheapparatus maybe located a typewriter, of. any. conventional or preferred construction which isdesignated :asa whole bythe reference 3 and, each of the said type sets may com priseha larger ,numberof keys and types than that shown on the drawing and oneoftllem maybea typewriter adapt- ,ed to Write any-othert desiredcharacter.

,Atthe ,front. of the apparatus is movably mounted a. carriage 5 having rollers 14 .running on rails&;a11d,a.rack.bar 6 cooperating vwith the usual trip pawl 7 which 7 controls the progression of the carriage after :each actuation of a key. A support 8 .for the book or paper sheet to be written .on is imountedto move vertically in-the carriage ,5 and in saidsupportis provided a platen '9 acted on Ebysprings 9 for keeping the ,printing surface in the ,required position. Said support 8 is provided with rackbars 10 each meshing with a {ratchet pinion ,ll rigid with ashaft 12. Aratchet wheel 13 ,is ,fastenedomthis shaftandds engaged by a pawl 14 pivoted on an arm 14 which ;is rotatable around the shaft ,12 and vis pivotally connected with ahandbarl5 mounted :to reciprocate in a, support 15 and by vmeans of this hand ,bar thevpawl -14 is op erated and vthe wheel ,13 is :rotated through one ,tooth, ,the support 8.being.thus moved vertically through .the space, of: one line .One ofsaidty-pe .:sets,.the one marked by I in ,the construction illustrated, is provided with ten keys 16 having the digits from 0 to ,9. Each .vkey iscarnied .by a ;lever 16 rigid .witha quadrant 1 7 vvhich is connected ytatie IS-toarod 19.,and thisrod is mount- :ed to reciprocate in the support 19 {of the ,machine ,framagandds hel, ,y a spring 20 in Figure .2

Each of said quadrants 17 is rigid with a shaft 37 and said ties 18 run over suitable grooved guide rollers 18.

Each rod 19 is provided at one end with a tooth 21 adapted to engage a hook 22 pivoted at one end of a reciprocating rod 23. This rod is pin-and-slot connected with one end of a lever 24 which is fulcrumed on a support 25 and has its opposite end pinand-slot connected with a type bar 26. All

- the hooks 22 of a printing type set are connected each by a rod 22 with a transverse bar 27 which is connected by a rod 28 with a lever 28 provided with a manipulating key 29. Said bar 27 is carried by two braces 27' fulcrumed at 27" in the machine frame.

The lever 28 is fulcrumed at 30 and is provided with an arm 31 which is pin-andslot connected with a link 32 pivoted to a lever 33 vfulcrumed at 34; the opposite end of said lever being held in engagement with a pawl 36 by a spring 35.

Each key bar 16 is fixed to corresponding shaft 37 extending throughout the length of the typewriter (figure 1) and journalled in bearings provided in the machine frame and not appearing in the drawing; and as hereinbefore described each of said shafts 37 is provided with a quadrant 17 for the operation of the printing mechanism 1819 23-2426.

Each of the other sets is similar in construction to the set hereinbefore described with the only difference that they are not provided with keys and therefore they do not require further description.

The sets I, II, III, IV (or at least some of them) are provided with vertical guides 38 in which are slidably mounted yokes each consisting of a transverse cross bar 39, having a key 41, and of vertical bars 40 and each of these bars 40 is in register with the rear end of one of the levers 33.

Said yokes are intended to control the levers 33 so as to put in operative condition the respective printing mechanism sets.

This operation is easily understood by in specting the figures 1 and 3, in which are shown the bars 33 of the sets II, III, IV, V the respective numerals of the sets being affixed to the references of these parts. In the embodiment illustrated it is assumed that the set I having the type operating keys is not provided with the bar 33 and associate yokes, but of course this arrangement could also be provided in the set 1.

By inspecting the saidfigures it appears that by depressing one of the yokes as 39f-40 by means of its key 41 the levers 33 and 33 are depressed against the action of their respective springs 35 and are then held in this position by the pawl 36 which is caused to engage them by the spring 36 and therefore in the sets III and IV the printing mechanism 3128-282722--2220 is in the condition of figure 2 and then the actuation of the keys 16, shafts 37 quadrants 17 ties 18 and bars 19 with teeth 21 causes the operation of the type bars 26. On the contrary in the other sets the levers 33 are held by their spring 35 in such a position as hold the hooks 22 removed from teeth 21 through the gear hereinbefore described.

As is obvious, by depressing any or all of keys 41, 41", 41 and 41 the pair of sets controlled thereby are put in operative condition; and further any of the sets may be separately put out of operation by lifting the respective key 29. It is to be noticed that the number of yokes 39--4041 may be any desired one for the purpose of grouping at will the operation of the several type sets notwithstanding that in figure 1 the yokes are shown in numbers of four for the sake of clearness.

In figure 2 no set apex has beenaffixed to the parts 39, 40, 41, as they would be of no use in said figure.

In front of each of the sets I, II, III, IV, the carriage 5 is provided with a tooth 42 (figures 2 and 5) which is pivoted in such a manner as to rock freely towards the left against the action of its spring 43 while its rocking towards the right is prevented by a stop 44. Said tooth 42 has a slope on its left face, and in the position it takes after the line of writing is completed it engages the end pin 45 of a rod 45 whose other end is connected with the tail of the pawl 36. This arrangement is intended to restore to normal conditions the several levers 33 after completing each stroke of the carriage.

After having put the selected sets in operative conditions, in the manner hereinbefore described, the operator successively manipulates the desired keys 16 and the respective types are struck by the desired gear in the desired sets, the writing being thus typed at the same time in the selected columns of the sheet.

When the carriage 5 reaches the end of its stroke, that is the right end of the written line, the pins 45' of the rods 45 are moved by the teeth 42 of the carriage against the action of the springs 36 and the pawls 36 are caused to release the levers 33.

The several type sets are thus carried into inoperative conditions each time the carriage has reached the end of the written line, and thus the following line may be written in any desired manner after having shifted the platen 8 one space by means of the hand bar 15..

It is understood that the carriage 5 is controlled by a usual spring drum as 5 which cooperates with the trip gears 7 to move the carriage one step at each action of a key; these devices not being particularly shown and described as they are well known its and may be of'any approved or conventional type.

The rods 26 of each printing mechanism converge towards one and the same printing point and the paper carrying carriage is moved one step with regard to said point at each key operation and the desired numerals are thus typed in succession at the side of each other in the several columns corresponding to thetype sets put in operation inthe machine.

Of course each ora number of --the-type setsmay comprise anynumber of type bars otherthanten, and some Oftllfi bars '26 may be provided with other types than that of numerals andthe machine may thus be used forwriting at the sametimethe same word or sentence on two or more points of the sheet.

The- -several type sets are of course located at a suitable distance from each other and each or a number of themmay consist of a usual typewriter.

It is to be understood that the described machine may be provided with any desired or conventional accessory device as a-tabuflator, carriage return key and the like. It may also'be associated or combined with a computing'machine or with any apparatus adapted to effect and record the results of additions and other computing operations.

By the 'described machine there may be produced at'the same'time and in a simple and easy manner writings of any kind on several columns or rows of a sheet or of a page of a book and this machine is particularly useful in bookeeping as it minimizes laborand errors.
