' Australia Application March 3, iaJNQ. 56,138 In Australia March I e l My Saidpatent describes a machine comprising "a frame-workfor supporting various parts, in- "cluding 'akey-board a bankjof fingers carrying striking heads, linkage betweenthe keyboard and the'banl; of fingers, an inked ribbon, a vertically arranged platen for supporting the paper to be printed on, and mechanism for traversing the platen horizontally and for raising and lowermg the platen while printing or "typing opera- "tions" are in progress. The mechanism for vertical adjustment of the "platen includes a shift lever movable between a pair of inclined or curved bars carrying horizontal transverse strips so arranged'as to leave a continuous vertical path between their inner ends Ior'movement of'the shift-' leverj-and slots between the strips.

'. lone of'tee' primary differences between the original machine and the present machine is that the platen is substantially horizontal and remains stationary during printing'or'typing opvable 'erations, and'the typing mechanism ism or. traversable over the platen; Reference will be made to the accompanying drawings which illustrate a'preferred practical embodiment of the invention. In the drawings: v Figure -l is a perspective "view of the embodiflmentf v I t Figure 2 is a perspective under view, in the direction indicated by the arrow'II'in Figure 1. Figure 3 is a part sectional elevational'view taken on the line III-III of Figure 1;]

' "Figured is a sectional elevational view-similar to a portion of Figure 3'. but showing a certain operative phase of a platen portion'of the em- "bodiment.

Referring now' to Figure l the improved machine may comprise "a horizontal frame I which may be-suitably supported 'upon legs 2 or the like and upon which aplate'n' 3 for m'ouiitin'gor sup porting the paper to be printeduponfis adapted Etosrbe :horizontallyi supported.

"be aliixed tothe supporting platen in any suitablemanner, but it is preferred that the platen be capable of relatively slight upward and down- Ward movement withrespect to the frame in such .a way that when' the platen is in the upper position, the paper thereupon is securely held between the platen 3 and transverse retaining strips flor bands provided and associated withthe frame; Inthisconnection I propose that flap .strips the hinged alq g jthe upper side edges of the platen}, and bespring. influenced in such a mannerthat when. the platen is lowered the flap strips? 6 rise to enable paper to be inserted or removed, and that when th'eplaten is raised the paper may be' firmly' retained .and secured by the flap'stripsf (see Fi .3. and 4). v A spring strip orband 1 adapted to clipf on flanges 8 provided on transverse members of the frame I, may be jprovided to retainpaper which may not ex A key-board '9 andnbankp of fingers ll with associated type heads and linkage mechanism are provided andmgunted upon a carriage C so arranged as to, bej icapablegofmovement or traverse both longitudinally and transversely in a substantially horizontal. plane across, saidsup.- porting platen. The carriage C, keyboardand linkage mechanismmaybe of anywell known commercial typewriter construction; the carriage illustrated being an Elliott Fisher apparatus.

For this purpose 2 the aforesaid carriage 2C is suitably s ppprtedupbn' rollers l2 or the like ,by a carriage-way' I3 extending transversely above the platen. This carriage-.way istmounted .upon rollers I4 and I47. cor'operating with runners. l6 provided on the carrying framework in such manner as, to permit the carriage-way l3 .to be moved longitudinally over the-said'lcarriage framework. l 1 I v j The carriage-way isalso provided with a trans verse1y extending axle l1 upon, which are mounted one or more pinions. [8 in engagement with a co-operating rack or racks l9 mounted upon the carrying framework inorder that controlled longitudinal movement ofthe carriage-way may be effectedin' a manner. later 'to be described. The rollers l4 may be mountedjupon the transversely extending axle l1.

, he fingers actu ted by the key-board 9 in corporatedwith the carriage mechanism are each provided with music or other appropriate symbol fheads for imprintingcorrespondingsymbols upon paper carriedby the platen in underneath re.- lationsh i'p with" said. carr iage. I, The carriage mechanism also includes such operating means as a back space, space bar, shift key, carriage quick release, for rapid traversing of the carriage, ribbon adjustment, line finder and the like as well known in connection with type-writing and like machines, and similarly a suitable'pawl and ratchet device or escapement mechanism is incorporated with, the carriage mechanism and adapted taco-operate with a rack 2| .or the .like upon the supporting carriage-way l3 in such a manner that movement of the carriage across the platen in predetermined spaced steps may be effected manually by the use of the space barorautomatically in timed relationship with the symbol heads actuated by the relative keys ina wellknown manner.

mallyllocated in the verticalipath ibetween the inclined bars 23. The arrangement is such that :a breakable coupling is provided between the block member 29 and the transversely extending axle l'lprovidedwith pinions l8 engaging with The type or symbol heads inscribe the paper through an inked ribbon in the .general location indicated by the arrow T, which is convenient for ready inspection of inscribed matter by the operator of the machine.

Normally thecarriage will automatically move vone space to the. right after each. note. symbol or thellikelhas been writtenonlthe paper. .It is desirable .that manually operable means beprovided to temporarily prevent this automatic movement,.so as to facilitate the'building up of musicalchords, arpeggiosigns andiother musical markings or lines whichrequirelongitudinal (or vertical with respect to amanuscript) alignment or continuity. .Accordingly,'a crank lever 22, with finger piece 22a and predetermined limits of movement, isprovided and the spindle. 22b there- Ifof= is connected'in anysuitable and simple inannezito renderthe escapement mechanism opera- ;tive, ornon-operative, as desired. a

, vfAipair of inclined bars'23, which may if desired be of-ouadrant configuration, are supported preferably .at one end of and attached 'tothe aforementione'dQcarriage-Way .l 3. These inclined bars are provided with horizontal strips 24 along their lengthso arranged as'to'leave a continuous vertifcalipathbetween their inner ends, and slots 24a between the strips. The'strips'atone side are sta gered in relation to the strips at the other *side. 'fAshift lever 26 is adapted to be swung through the verticalpath between the strips upon the inclined bars, the shift'lever also being capableofJslightmovement to the right and to the leftfs'o as to be engaged within a slot formedbetween' an'adia'centJpairof the horizontal transverse strips.

7 ,In order to relieve the staggered transverse strips 24;which may be relativelyfra'gile, "from being repeatedly engaged by the .shift lever 28,

ftwo series ofpins or studs 21 may project in staggere'd relationship immediately behind the respective st'rip's'tofiform abutments against which thejshiftlever can bear when moved into its adjusted positions.

The shift lever 26 may comprise a rod pivoted atits inner .end as will be hereinafter described andpro'vided at its outer endwith a 'T-shaped handleZGa or the like in such manner that the shift lever may be turned or twisted as well as being swung in a vertical manner between the inclined bars. .Adjacent itsinner end, the shift lever (rodmaybe provided with a flexible union to permit of the slight sideward movement to enable the shift lever to be engaged at one or the other side ofi'the vertical path between them- .clined'bars 'with'the transverse strips. 1 'Acc'ordingly at itsinner end, theshift-lever is 'carried'by a' yoke member 28, which is supported upon ablock member '29 pivoted about one end fOf the transversely extending. axle or spindle l1 co-operating racks l9 extending longitudinally uponthe carrying framework. .15

The breakable coupling may comprise a flange 34, afiixed upon the transversely extend- "ing axle l1,"provided with holes 36 concentrically "formed'around the outer face thereof in predeflange, 'bytvvisting of, the shiftlever, and engagement of the trigger 38 with a projection 31a upon the pin 31, no rotative' movement will be imparted to'the flange or transversely extending axle if the shift lever Ibe lthenmovedupwardly or downwardly betweentheinclined bars. The pin is normally influenced to engagement with a'hole in theflange'by'means of a spring 39 or the like, and the trigger38 is normally maintained out of engagement with projection '3lalby means of ahelical spring 26a operativelyconnected withtheshiftlever 26.

Alternate means for appropriate withdrawal from engagement of the pin with the flange may be used; such for example as a flexible cable which may beof theBowden type, suitably oper- -ablefroma control on the :shift lever.

It is desirable that the end of the pin relative to the .fiange be of tapered configuration to ensure smooth engagement with the latter.

It will thus be apparent that when the pin 13'! is engaged with the flange 34 upon the laterally extending axle t1, and the shift lever 25 .is moved upwardly or downwardly between the inclined-bars or quadrant,the rotation/of the laterally-extending axle and its pinions l8 in engagement with the racks l9 upon'the carrying framework will cause the carriage-way l3 and carriage C thereon to be moved longitudinally across the paper supporting platen 3.

If the pin is withdrawn and 'theishift lever moved through the quadrant or inclined bars, no movement of the carriage will take place but this will occur if the pin is again permitted to engage with-the flange by twisting or releaseof the shift lever control.

'It is desirable that the holes 36 or co-oper- .atingnotches uponthe flange hereinbefore mentioned be provided in predetermined-spaced relato' another part of the quadrant scalefiasindieated by the horizontal transverse stripsthereon, without effecting any movement of the carriage and carriage-way longitudinally acrossthe platen or supporting framework.

A'handle 4| upon'asuitable portion of thecarriage-way' I3 is providedfor expeditious manual steadying, or movement,'of the carriage-way longitudinally across the-platen.

It willthus be apparent that a means such-as outlined affords a ready way of changing from stave -'to stave, for example, when operating the machine in the printing or typewriting of music; and the form of mounting of the carriage mechanism with relation to the paper carrying-platen affords a ready .way' of. traversing the former over the "latter in operative manipulation of the machinepx The. horizontal transverse strips-24. maybe arranged in *spaced. relationship or positioning along the inclined bars or .quadrantrinmuch the same manner as has been'described in mysaid patent and may be provided with identification marks or configurationsiidentifying the appropriate strips with the stave line positioning of written music as; described in mysaid previous patent. L Y

Itis desirablethat spring tensionor like means, suchias'springband spool 42, be provided to influence the carriage along) the carriage-way in" a predetermined direction working in association with the carriage ratchet andescapement mech- ;anism. It maybe desirable; that spring-tension .or like means be provided toinfluence or,con-' trol the longitudinal-movement of the carriage and carriage-way across the platen. In this connectionI prefer gravity weights, one of which is shown at 43 connected by cord 43a to an appropriate portion of the carriage-wayl3.

If so desired, the runners 16 may be on a downward incline towards the front of the maohine, ratherthan horizontal, thereby enabling the carriage-way, and supported components to be normally influenced forwardly under the influence of gravity. i p i I The-means for effecting; raising or-lowering of the'platen 3 will now be described, with particular reference to Figures 2, 3 and Accordingly, the platen 3-is neatly accommodated between the side pieces la and lb of the frame I, anyupward movement of the platen being limited by the overhanging; portion of runners I6, against which. the flap strips 6 may engage. i

-A- pair of shafts 48 are supported horizontally 5 by, and longitudinally of, theframe I, A plurality.of pairs'of arms 41 and are: affixed; to the-shafts 4,6, the innerends .of the arms .441 and 48 being respectively connected by tongue and slot telescopic connections;

Rollers 49 are rotatably mounted on the upper faces of the arms 41 and 48, and'the platen 3 is adapted to be supported-upon these rollers 49.

An arm 5l1radiallyoutstanding from one of the shafts'lfiiis connected by link 52 with a minor arm 'member 53 outstanding from-a cross :shaft 54;.atione end'o'f which is a handle member: l The shafts are influenced by springs "51 to .normally maintain the .arms 41 and 48, and. the platen 3 supported". thereby, in an upward or raised position. 1 'i If. the handle member 56 is actuated the c'ross shaft 54 will be rotated, causingfin efiect,. the .arms 41 and" to be moved radially by the shafts swans the platen to be lowered against menu;

fluence of springs 51 (see Figure 4).

A rod 58 (see Figure 2), the outer'end of which is provided with a knurled or likefinger-pieceifl, and the inner end of which is screw :threa'ded, is rotatably supported by a portion'of the frame I, the screw threaded portion beingadapted .to

- co-operate with a screw block 6 I-ymountedLonth've underside of the platen-3. By this means',gl ongitudinal movement or adjustment of'the ,platemt, 1 supported by rollers 49, upon the machine framek may be conveniently and expeditiously-er;

fected. l Y

With due regard'for the different character'- istics of themachine and the arrangement-got component parts thereof, the-operation of the machine is substantially-on the lines asdescribed in my said previous patent. However, it is considered that the movement of-the carriagelaterally and longitudinally,- over the paper uponaa horizontal platen,. provides many'advantages in operation and practice, amongst which are ;the

ease of operation and the ready-visibilitm-of he work being executed. I

It will be appreciated that simply by twisting the shift lever, or by othermeans releasingthe pin from thedriving flange, the carriage and carriage-way may be moved longitudinally over and away from the work being executedto permit of thorough inspection of the same. I

For the purpose of readily inscriblng; desired lines or marks, such as for example stave lines.

upon the paper or, the like carried upon ,the

platen, I propose the use of an appropriate num ber of pens which may be supp'orted-in asubstantially vertical position, in desired relationship,

one to another, from, orby the carriage mechanism. I have found that a pen of theball-point type possesses excellent characteristics for such a purpose, the ink therefromfdrying; practically instantaneously, thereby obviating; smudgin'g, whilst the thickness of line produced may be readily controlled by variation vof.-thepressure of the pen upon the paper. v I

For convenienca the previous proposal -isZ -not1 illustrated in the drawings, whereinis shown .a printing roller 63 having a set of five appropriately spaced circumferential peaks which are adapted to bear, against an inkingpad {not shown) and which may becausedtobearupon paper, or reproducing stenciL-upon the platen by depressing finger-piece 64.

Such a device as hereinbefore described is of particular advantage when a- .master wax stencil,is being cut-for subsequent reproduction It will also be appreciated that by the useof a single pen-instrument appropriately supported and traversable in relation to the paper a-single line or lines may be readily inscribed as desired;

Curves or how lines may be readily inscribed by simultaneous lateral and .longitudinalmovement of the carriagewhich carries the pen,over

the paper. In the drawings,a-singleroller wheel 66 isshown supportedfor inscribing single'lines; it may be brought :into engagement :with'the paper or stencil upon the plateni-by-sdepressing Whilst the foregoing descriptionrelates to an embodiment of the machine which. at.:pr.esent is preferred, it'is to be understoodithatzitissusceptible to various modifications, refinements and/or additions without departurefromthe true spirit and scope of the inventiomuaswdefined;by .the' appended claims.
