No. 827,514. Specification of Letters Patent. Patented July 31, 1906.

Application filed February 1, 1900- Serial No. 3.59

Be it known that I, HARRY S. DUKES, a citizen ofthe United States, residin at Little Rock, in the county of Pulaski an State of Arkansas, have invented a new and useful Vertical-Plane Type-Writer, of which the following is a specification; 1

This invention relates to type-writing machines,.andhas special reference to an improved machine of "this character having printing mechanism comprising means for operating upon work held in an upright position; and the invention also contemplates be especialli; useful in printing upon the pages of boo s, although the same is adapted for printingflupon sheets or any work-held in such a Way that the printing-point thereof In carrying out the foregoing object-that is, to provide 'agwriting mechanism ada ted for printing u on sheets or any work he d in such away t at the printing-point is intersected by a vertical planethe invention contemplates a simple, effective, and thoroughlypractical type-bar action embodying an arrangement of parts insuring completely-visinection is to provide a novel arrangement of operating connections for the type-bars possessing special utilit in connectionwith that class .of machines nown as front e strike writing machines, wherein the type"- bars strike rearwardly upon the front of the platen irrespective of whether this platen is-in the conventional roller form or is of the 'flat type used i record and equivalent machines.

compactness and simplicity in the type-bar action, but also provides for maintaining-a tireaction, as well as roviding for thedesirable feature of visibi 'ty of the writing.

A further object of the invention is to obviate the objection to book and-'similar't pewriting machines which have a traveling eyboard, .which in some forms of machinesnot only moves transversely with reference to the sitting osition of the operator, but also toward an from the operator. This trav-. eling keyboard is'quite objectionable, for the reason that it not only rendersthe machine more inconvenient and difficult of mani ulation, but also greatly impairs the. s cc of the'operator .To overcome this di culty,

ways maintains a fixed relation to the oper+v ator and to associate with this stationary keyboard a traveling type-bar action carried by the type-carriage.

Another object of the invention is to efployment of a stationary keyboard which al 7 feet a constant operative connection between the traveling type-bar action and the sta tionary key-action, which wilpermit of the uniform and-positive operation of'the typebar action irrespective of the position of the traveling type carriage, thus insuring the necessary accuracy ofmovement for the typebars. The invention also has 111 view manyother objects besides those stated,-'whfich will hereinafter more readilya pear-as the same is better understood; an sists in the novel construction, combination, and arrangement of-parts hereinafter more fully described, illustrated, and claimed.

The fundamental features of the invention the invention I coninvolving the structural features of the type action, the stationary keyboard or key-action, and the traveling type-carriage, together with the constant operative connection between the said type-bar action'and key-action, are necessarily susceptible to a wide range of modification and to various adaptations in different formsof machines without departing from the spirit of the invention; but a preferred adaptation of the principal instrumentalities of the invention. is shown in the drawings, in which Figure 1 is a plan view of a type-writing machine embodying the features contemplated by the present invention. Fig. 2 is a front elevation of the machine shown in Fig.

- Like numerals of referencedesignate corresponding parts in the several figures of the drawings.

. In carrying out the present invention the essential feature thereof resides in the arrangement of the type-action in such relation to the key-action that the type-action is permitted to have a traveling movement with the carriage, while the key-action retains a relatively stationary position with reference to the type action .and to the o erator, thus 1permitting of the employment'o a stationary eyboard. This relation-of the tylpe-action tothe key-action necessitates the provision of a constant operative connection between .the two actions, whereby the type-bars may drawings this base'is preferably in the form of'a casing which provides for housing the working parts of the key-action. The base may therefore be properl termed a basecasing and is of a 'enera ly rectangular configuration, being 0 a sufficient length toaccommodate' the traveling) movement of the ty e-carriage. The said ase-casing 1 is provided at the front side thereof and centrally between itsends with a forwardly-extendin keyboard pro'ection or case2, above whic is arranged t e stationary keyboard, consisting' of the keys hereinafter referred to.

. The said base-casing is also 0 en atythe top throughout the entire length t ereof and has fitted to the upper side thereof a air of o"- posi'telyarranged track-rails 3. he trac rails 3, which are located at the top of the base 1, are dis osedin parallel relation respectively at t e front and rear sides of the base and extend longitudinally of the latter the full length thereof to accommodate the movement of the traveling type-carriage 4. The traveling type-carria e 4 essentially consists of a casing 5, within w 'ch are housed the 7 working parts'of the ty e-action, to be pres ently referred to, and t c said casing is proare sustained in vided with the front and rear traveler-rollers 6' and 7, which travel, respectively, on the front andrear rails 3, the rear traveler-roller 7 being preferably peri herally grooved to take over the rear tr'ac -rail and prevent transverse displacement of the carriage from the track. v

The type-carriage casing 5 is open at the bottom to communicate with the interior of thebase l'in all positions of the carriage. Within the carria e-casing is arranged a pair of horizontal trac -rails B, which track-rails supports and are isposedtransversely of the carria e and at 'ri ht angles to thelongitudinal isposition of the main trackrails 3 for the carriage, the said interior transverselydisposed track-rails 8 withinthe carriage being designed for the support of the horizontally-movable shiftable type-bar carrier 9, which has a shifting movement. transversely within the type-carriage for the urpose of effecting the printing of upper or ower case characters, as will hereinafter appear. The shiftable type-bar carrier 9 essentially consists of a skeleton rectangular frame provided with supporting-rollers 1 1, riding upon place by means of suitable the stationary track-rails 8, which are sup- I ported inside of the type-carriage, and the said skeleton frame of the carrier not only provides for the support and horizontal movement of the type-basket, but also provides for the support of the elements having .direct connection with the type bars, thus providing for supporting and housing within the shiftable type-bar carrier nearly the entire type-action. r

The type-basket, which is supported wi thin and carried by the shiftable typebar carrier 9, essentially consists of the vibratory or swinging type-bars. 10 and the u right type* bar hanger and-rest-rings' 12 an 13, respectively, said rings beingof the usual arched or semicircular form and the type bars 10 grouped in acircular series within the rings to complete the type-basket. To provide for causing the type to print upon a vertical plane, it is necessary to have the type-bars normally lying in substantially horizontal positions,

7 while the hanger and rest-rings12 and- 13 are disposed in vertical or upright positions and arranged'in arallel-s aced relation,as clearly shown in 1g. 30f t e drawings. The upright arched rest-ring 13 is arranged in an intermediate position between the type bar hanger-ring 12 and the front side of the type-- bar-carrier frame and subserves the usual function of a'irest or support for the swinging 'IIO ends of the lt'ype-bars 10 when the latter are i in their at+rest positions, while the upright hanger-ring '12, which is disposed at or near the rear side of-the type-bar-carrier frame, provides for the support of the hangers on which the type-bars are pivotally mounted.

It will thus be-seen that provision is made for arranging 'the type-basket within the frame of the type-bar. carrier in a horizontal position in contradistinction to the upright position of the type-basket in those machines in which the type strike downwardly upon a horizontal plane. By reason of the horizontal arrangement of the type-basket within the shiftable'type-har carrier a clear view may be obtained longitudinally through said basket by simply,constructing the carriagecasing5 at the front and rear sides thereof with openings, and inasmuch as the carriage casing is also necessarily open at the top to accommodate the throw or swin of the typebars an unobstructed view is Trad through and over the type-basket upon the writingplane, thus insuring visible writing.

Each of the swinging type-bars is provided at the free swinging end thereof with a pair of laterally-offset divergently-disposed type-carrying arms 14, to which are: fitted the type or type-heads 15, whose printingfaces are disposedat an angle to each other and either of which type or type-heads is adapted to be placed in the'printing position by shifting the fulcrum of the type-bar toward or from the printin -plane in the manner to .be presently expTained. The typebars 10, which are provided with a pair oftype having their printing-faces disposed at an angle -to each other, are pivotally supported by the type-bar hangers '16, applied in a circular series upon the upright arched" fitted to thering 12.

hanger-ring 12 and contiguous to their pivotal supports on the hangers 16, which are Each of the swinging type-bars 10 is provided with the usual angu larly-projecting heel 17, to which is pivotally connected one end of the connectin -rod 18, which extends longitudinally wit in j the frameof the shiftable type-bar carrier and is pivotally connected at its other end to one arinof an operating-lever 19, preferably in the form of a bell-crank and pivotally supported t its angle, as at 20, on the bearinghanger -1 ,fitted to a lever-supporting bracket 22, mounted within the front portionof the shiftable type-bar-carrier frame and in advance of the type-basket.

There is a" bell crank-operating-lever 19 and a rod connection, 18 for each swinging type bar, and in order to secure a compact arrangement of the several. bell-crank levers 19 an their proper relative positioning with reference to the key-action element with which they are associated the lever-supporting bracket 22 is referably of the peculiar construction plain y shownin Figs. 3 and 5 of the drawings. This supporting-bracket 22 is arched from side to side of the shiftahle type-bar carrier 9 to conform approximately to the curvature or arching of the type-bar hanger-ring, whereby all of the t pe-bar-operating levers 19 may bedispose in vertical planesin-parallel relation to each other, as

of the drawings.

shown in Fig. 40f the drawings, thus providing means for securin a direct pull upon the heelends of the type ars 10 by a downward pull upon the horizontally-disposed arms of said levers 19. This secures a direct and positive movement of'each type-bar without any lateral strainon the pivots thereof. In addition to being transversely arched within the shiftable type-bar carrier 9 the leversupporting bracket 22 is preferably constructed of a single bar, whichmay be suitably fastened at its end portions, as at 23, to-

the sides of the type-bar-carrier frame, and at an intermediate ortion, as at 24, to the front of the t pe-hancarrier frame, and thereby-provide or firmly bracing the said bracket in its fixed 'position withinthe front portion of the shiftable type-bar carrier. To provide for the proper support of the bellcrank levers 19in separate groups, the said lever-supporting bracket 22 is constructed with a series of offsets forming a plurality of hanger-bar portions 25, to which the bearinghangers 21 for. the bell-cranks are fastened. The several hanger-bar ortions 25 of the bracket necessarily have t e curvature of thebracket and are disposed in concentric relation, ,but in diflerent'vertical parallel planes, and those hanger-bar portions'25 which liei'n the same circular and the samevertical plane provide for the support of those bellcrank levers which belong to the same group.

It will therefore be seen that certain bellcrank levers 19 belonging to the same group and lying in the same vertical plane are arranged, respectively, at opposite sides of the transverse center of the bracket, as plainly shown in Fig. 5 of the drawings. Furthermore, the proper grouping and arranging of the bell-crank levers 19 is provided for by having the lever-supporting bracket laterally inclined to dispose the concentrically-arranged han er-bar portions 25 in different horizontal p anes, as plainly shown in Fig. 3

Also it may be found necessary or convenient-in. the compact grouping of the hell-crank levers 19 to reverse the position of some levers with reference to the others, whereby certain levers will have the rods 18 connected with the pendent arms thereof, and vice versa, such reverse arrange ment of levers being also shown in Fig. 3.

From the foregoing it will be observed that the maintenance of a uniformity of leverage throughout the type-action and also the permanent relation of the several parts of the type-action are reserved by mounting the intermediate hel -eranks 19 upon a su port separate from the hanger-ring, but shi table therewith'in the shifting movement of the type-bar carrier for'eifecting upper and lower case printing. Furthermore, it will be observed that in the arrangement described there is employed what maybe properly termed a "plurality of sets or rows of intermediate bell-cranks connected to the type bars andkey-levers, one set: being arr-anged' rorwardly of anothera'nd-eachsetor row ex tending transversely of the machiner Each of the type-baroperating levers or bell-cranks 19', which are "mountedwithin and shiftable with the type-bar carrier' 9, has

a pull-rod connection 26with oneend of =a1 vertically-swinging typeaction connecting lever 27, arranged within the lower-portion of the traveling type-carriage hrelots the plane of the shiftable type-bar carrier" therein; There is of course the same number'of type ac tion-connectin cranks 19 within the type bar carrier=,'- and the said conne'ctingdevers 27 are preferablfiin the form of straight bars pivotally supported at one end, as at 28 ,in a common pivot-plane within the carriage-casing contiguous to the rear sidethereof. The straight connectinglevers 27 are arranged in parallelism inaeom mon horizontal plane, but are 'necessarilyiof different lengths to provide for'b'ei g pnoperly connected with the bell-crank le ers 'i9' and;

also with the l ey=actionwithin the stationary base 1; but it will be'undei'stood'that inasmuch as the said-levers 27-are arranged with in the type-carriage fandtravei therewith the same necessarilyconstitute-parts or elements of the traveling=type-action in contradistin'c tion to the fixedly-positioned elements of the key action within the stationary base 1-. However, it will be observed thatss iar asthe type-bar action parse-is concernedthdlevers 27 are, in effect, the key l'evers; inasmuch as they are linked directly to the'ke'ysthrough the intervening connections with the other ke' -leve'rs 44, to be referred to;

There is oneof "the 'keyaction'motiontransmitting elements or rails for each operating-key and each type-bar, and to secure a practical and very compact arrangement of the motion-transmitting elements or rails 36 the same are not only grouped in independent horizontal series, but all of the said horizontal series are disposed in a common vertical plane, whereby the elementsor rails 36 in the adjacent. series will be vertically alined in a common vertical plane. There may be any number of the motion-transmitting elements or rails 36 in each horizontal series thereof, and there may also-be any number of horizontal series grouped one above the other, accordin to the requirements of the particular mac ine; but by preserving the order shown in the drawings the connections with the operating-keys and with the type-action may be effected in a'simple and positive manner to insure the most direct transmission of motion from an individual operating-key to the particular type-bar associated therewith.

The parallel-spaced relation of the motiontransmitting elements or rails 36 in each horizontal series and the vertical alinement of said elements or rails in the adjacent horizontal series providesor leaves verticallyalined spaces throughout the several series which are adapted to receive therein the coupling-rods 38, which provide an operative connection between the key-action motion-transmitting elements or rails and the type-action-connecting levers 27. Each type-action-connecting e connected thereto, as at 39, the upper end of one of the coupling-rods 38., the lower end of which coupling-rod has a slidable or traveling connection with the element or rail 36 associated therewith. 'This slidable or travcling connection between each coupling-rod 38 and the motion-transmittingelement or rail 36, in connection withwhich it operates, may consist of any mechanical expedient adapted. for the purpose, but is preferably. in

the form of a flanged traveler-roller 40, offsetlaterally from the lower endof the rod 38 and engaging with the lower edge or under side of the motion-transmittingelement, or, rail 36. At this point it may also be ob-. served that each coupling-rod '38 is preferably bifurcated at its upper end to insure a firm pivotal connection between the same andv the type-aetion-connecting lever 27 to,

prevent lateral strain of the connection.

It has already been axplained that the, essential feature of the combination between a each type-action-connec'ting lever 27 and the key-action motion-transmitting element 36, associated therewith, is to provide a suitable ver 27 has pivotally operative traveling connection between these parts, whereby the type-action-connecting ever will be positively and uniformly operated with the type-carriage in any position;

but while the flanged traveler-roller 40 on the coupling-rod 38 effects this result in a practical manner still the modification shown in Figs. 8 and -9-rnay be resorted to for the same purpose. This modification simplyconsists in constructing. the element or rail 36 in a folded flanged form to provide the same with a guideway 41, extending longitudinally from end to end thereof and slidably receiving therein the hook 42 at theilower end of the coupling-rod 38., The hook 42 will freely slide in the guideway 41 of the element or rail 36 as the carriage is moved upon the suppor-ting rails therefor, andwill there fore accomplish the same result as the con struction previouslydescribed; but it will be understood, as already stated, that other modifications of this part'of the invention may be resorted to without departing from the spirit or scope thereof.

The specific grouping of tne key-action motion-transmitting elements or rails 36, as

' described, permits thecoupling-rods 38 to be arranged in the vertical spacesrunning between the vertically-alined elements or rails, and each alternate vertical space receives therein as .many of the coupling-rods 38 as there are vertically-alined rails on both sides of such space, inasmuch as proper connection can be made with the rails by having the flanged traveler-rollers 40 of some rods projecting laterally in one direction to engage with the rails at one side of the space and by having the flanged traveler-rollers 40 of the remaining coupling-rods'of the same group projecting laterally in an opposite dircctlon to engage with the other rails at the opposite side of tne same. space, asplainly shown in Fig. 3 of the drawings; but it will of course'be understood that I this arrangement may, be varied to suit the requirements of the particular machine beingconstructed without departing from the essential features of the connections already set forth. The remaining alternate vertical spaces running between the vertically-alined elements or rails 36 are designed to accommodate or receive therein certain of the upright connecting-rods 43 for the key-levers 44. In the arrangement shown some oft-he connecting-rods 43 are necessarily-arranged exterior to oroutside of the vertical plane of the several series of motiontransmitting elements or rails 36 to provide for the proper key connections with the front preferably consists in fitting the upper exing-rod 43l,has ,an adjustabloconnection 46 with an angle-plate 47, arising from a clip or sleeve 48, fitted toithe key-lever'44'. The several key-levers ,44 are grouped in a norizont'al series within the bottom portion of the base or base-casing 1 and are pivotally supported .at their rear-ends, as at 49, in a common pivot-plane, the front ends of the keylevers having fittedthereto the lower ends of f slldable interlocking connectlon wlththe ad the vertical stems 50, extending through the front keyboard extension 2 of the base and carrying at their upper ends the operatingkeys 51, which keys are arranged in the usual stepped order and constitute the stationary keyboard of the machine. The spacing-bar 52 ofthe keyboard is supported by levers 53, grouped with the other key-levers 44 and mounted in the same pivot-plane, and all of said. levers are designed toactuate the letterspacing mechanism a of the machine. This may be'conveniently accomplished in a practical manner by arranging beneath the entire series of key-levers a universal-bar 54, having an operating connection 55 with the dog-carrying lever 56 ofthe letter-spacing mechanism 57 suitably mounted within the stationary base-casing. This letter-spacing mechanism may be of any approved type, but in the form shown in the drawings not onlyin- 'cludes thedog-carrying lever 56, but the feedshaft 58, carrying a'pinion 59, meshing with a rack-bar 6Q, fittedto and carried by the traveling carriage 4. Thevsaid letter-spacing mechanisrn is necessarily actuated upon the movement of each operating-key or the space-bar 52, and therefore provides for the necessarymovement of the carriage upon its support ing-track to effect the letter-spacing. In connection with the letter-spacing mechanism there is associated with the carriage any suitable actuating device, such as a spring-actuated drum60, supported bythe base, and the usual tape'60 winding, and unwinding on the drum and having a connection with one end'of the carriage, said partsbeing indicated in'Fig. 1 of the drawings. V

The line s'paciug' forthe work is effected through the medium of a support which may be associated with the machine for holding the work in an upright position; but as this support forms no part of the present inventlon the same is not shown or described here in. This, however, is fully shown in my companion application, filed of even date l herewith, Serial No. 35,938; but the position of the platen is indicated by the dotted lines and the referencetharacter P in Figs, '2

and 3. I

It has already been explained that in order to effect the printing of upper and lower case characters it is necessary to shift the fulcrum of the typebars 10 toward and from the vertical printing-plane, which shifting of the fulcrum is accomplished by the horizontal shifting movement of the type-bar carrier 9 within the traveling type-carriage, and while different means may be resorted to for securing the shifting movement of the type-bar carrier the mechanism or. device illustrated in the drawings for this purpose may consist of a rock-shaft 61', mounted within the base and carrying the swinging adjusting-arms 62, extending upwardly above the base, and carrying at their upper ends, the longitudinally-arranged shifting-rod 63, which has, a

justable slotted lugs 64, fitted to the shiftable type-bar carrier. The shift-rod 63 compels the type-bar carrier to travel'in a constant plane aside from the shifting movement thereof, and the slotted lugs 64 are adjustable, was to be made to closely engage the shift-rod 63 without binding thereon. Suitable springsare associated with the shifting device or mechanism .to normally hold the shiftable type-bar carrier in its closest position ,to the printing-plane, whereby. the typebars will normally strike. lower-case characters, and said s ring (designated by the numeral 65) may econveniently attached to the rock-shaft 61 to exert a tension in adirec-' tion to provide for normally swinging the adjusting-arms 62 .rearwardly, whereby the type-bar carrier will be normally maintained in the position described.- Should it be de -f sired to print upper-case characters, it is only necessary to ,s 1ft the type-bar carrier forwardly within the type-carriageto move the fulcrum of the type-barsaway from the printing-plane. complished by providing the rock-shaft 61 This movement may be acwith an arm 66, having a link connection 67 with the swinging lever 68 of the shift-key 69, said lever 68 being group ed'with the horizontaLseries-of key-levers 44 and the levers 53 for the spacing-bar of the keyboard.

In order to positively limit the'shifting movement of the type-bar carrier!) in either direction, suitable stops are associatedtherewith; The preferred arrangement of these stopsis shown in the drawings and consists in arranging, respectively, .at opposite sides. ,of the swinging 'arms 62 the oppositely-located lugs 70, carrying adjustable Stopscrews 71, which are adapted to be respectively engaged by the arms 62whe n thrown either forward orbackward, said lugs 70 being projected from the stationary'base, so as to occupy fixed positions. The said stop screws 71 not only serve in the ca acity of limiting-stops to limit the swing o the'adjusting-arms 62 for the type-bar carrier, but also provide simple and reliable means whereby the alinement of the type may be regulated.

From the foregoing it is thought that the construction, operation, and many advantages of the herein-described machine will be readily apparent to those familiar with the art without further description, and inasmuch as the fundamental features of the invention herein pointed out are necessarily susceptible to a wide range of modification and even susceptible to adaptation. to different types of machines printing upon difi'erent planes I will have it understood that various changes in the form,'proportion, and minor details of construction may be resorted to Without departing from the principle or sacrificing any of theadvantages of the pres ent invention.
