Application June 13,:

23 Claims.

This invention relates to typewriting machines and particularly to typewriting machines which are intended to print a plurality of characters simultaneously on'a paper strip.

One of the principal objects of the invention is to provide a small compact typewriting machine of the'type in which a plurality of characy ters may be simultaneously printed on a paper strip, the outside dimensions of the machine being but slightly largerrthan the area of the keyboard. -Y

Another object of the invention is to provide e a typewriting machine for printing a plurality of characters simultaneously on a v paper strip in which the. paper strip is fed into the side of the machine.

Another object of the invention is to provide .a typewriting machine for printing a plurality tion between the types and keys vbeing such'that the printing order of the types-from front to back maybe independent of the order of the keys.

Still another object of the invention is to provide a small compact typewriting machine with keys which have a substantially straight-line motion, so that the /angle of a key does not change materially when tha/key is operated.

Another object of the invention is to provide a y.'lypewriting machine with a plurality of types operated by bars arranged side by side and transversely tothe planes of operation of the keys.` 'Still anotherbbiect'of the invention is to provide a typewritmg machine. as defined m nie last paragraph, with means to shift the 'type bars so as to print other types associated with the bars.

Other objectsv ofthe invention-will in part be obvious and willv in part appear hereinafter.

'A The invention accordingly comprises the features ot construction, combinations of elements,

and arrangement of parts, which will be exem- 1941, serial No. 397,886

As has already beenstated, the invention is particularly applicable to a typewriting machine which is adapted to print a plurality of characters simultaneously across a paper strip. Such a machine is a stenot'ype machine in which the charactersthus printed across the paper strip represent words or syllables in accordance with a stenotype code. In stenotype lmachines heretofore used, a paper strip is fedfrom frontI to backI of the machine, the platen being positioned at the rear, spaced from' the keyboard, and the keylevers Aand type bars being positioned in the space between the platen and the keyboard. The keyboard is necessarily-of a certain general size because it `is limited by the size of the human hands. Keys must necessarily be large enough to be manipulated by the fingers and they must 'f be far enough apart so that when any given key is struck intentionally an adjoining key is not 5o likely to be struck erroneously in conjunction with it. Therefore, if such a typewriter is to be made smaller and more compact, the keyboard can not be decreased in-size below the minimum size as defined by the size of the hands and nl lgers. 'I have found, however, thatv I can make such a machine much smaller and more compact, and thus attain one of the principal objects of the invention, by feeding the paper strip into the? machine in a direction transverse to the usual direction.of feeding such paper strip, and providing the platen and types at the side of the keyboard. A novel arrangement of key levers andtype. bars makes this possible and provides a machine which is but little larger than the actual size of the keyboard. f

The machine of my invention comprises a frame formed of two end plates I2 and I3. (Figs. 1, 3, -and 6) which are held in spaced relation by rods I4 and I5 at vthe lower ends thereof and.

rods I6 and I1 at the upper ends, the rods being attached to the plates in 'any suitable manner. y

The plates I2 and I3 arejcut away so that they have the appearance of an inverted U, and both slope upwardly from front to back of the machine, as indicated in Fig. 6. .'I'he cut away portion of the plate I2 provides downwardly extending front and rear members I8 and IS which may be anged to receive rubber feet 20 and2l respectively. Similarly the cut away portion of the plate I3 provides frontI and r'ear members 22 and` 23 which are flanged to receive

rubber feet

24 and 25 respectively. The plate I2 which is at the left side of the machine is provided with arms 26 and 21 which extend towards the left at right angles to the plate for the purpose of supporting the platen 28 and associated mechanism. The platen may consist of a rubber covered roller, and is mounted on a shaft 29,

Y theends of which pass through suitable hces 'dinal movement. To this end the plate I3 is provided with flanges 33 and 34 which are spaced apart, as indicated in Fig. 2, and support vbetween them a bar 35 which is provided with transverse parallel grooves 36, equally spaced along its length. The har 35 may be held in place between the flanges 33 and 34 by suitable. screws 31 and 33. The right ends of the Atype bars 32 are provided with longitudinal slots 39 (Figs. 3 and 4) through which the bar 35 extends, and the edges of the slots t into the.

grooves 36 and thereby space the right hand ends of the type bars, at the same time permitting longitudinal movement thereof. .The other ends of the type bars are provided with slots 40 thereof. In addition, the lower edge of the bar is bent. at right angles, forming a flange 41, this construction insuring a rigid type bar which Ywill not bend under conditions of operation;

The left handend of each type barris provided with at. least one type 43 while certain of said bars Ahave apair of types 48 and 49, the former above the latter, the type 48 being in position to print when the type bar is moved towards the platen in the normal position of the plate 44. Means, to be hereinafter described, is provided to raise the plate 44, so as to cause the types 49 to print when the type bars are moved towards the platen.

A suitable inked ribbon 50 is provided and is caused to move in a manner to be hereinafter describedbetween the types and the platen, and a paper strip 5I is caused to be fed over the platen in a manner also to be hereinafter described.

'I'he type bars 32 are individually urged towards the right side oi the machine by means of at springs 52 (Figs. 4 and 6) which are supportedon the plate 44 by means of a bar 53 held in place by suitable screws 54. These flat springs 52 extend downwardly from the top of the plate and enter slots 55 in the upper edge of the type bars 32. Longitudinal movement of any type bar towards the lplaten will cause the associated spring 52 to be bent to the left, whereupon removal of the force acting on the type bar will permit the spring to return the type bar to its normal position towards the right of the machine. The left end of the slot 39 of each bar determines its limit of movement, vtowards the right, while the type itself,v striking against the ribbon and paper, backed up by the platen, determines the limit of movement to the left.

. The machine -used for illustrating the invenand groups of characters to represent sounds in accordance with the principles -of stenotypy,

the upper row of types on the type bars being arranged in the following order from front to back of the machine:

In order to move these types against the platen, a plurality of keys (Fig. 1) are arranged in two rows in the following order across the keyboard:

` S T P K N `S K W R Y FPLTD 'RBGSS 1 The middle key in the upper row is used to oper- Y ly to feed the paper strip, in a manner to be herethrough which a rod 4I passes, the rod being supported between anges 142 and 43 which extend outwardly towards the left from aplate 44 mounted in the machine in a manner to be hereinafter described.. Suitable separators 45 'are provided on the rod'4I to maintain theends of the type bars 32 in spaced relation.

VI make the bars 32 out of sheet metal and place them edgewaysinthe machine, and in order to strengthen the bars, I prefer to give* them a configurationy shownin Figs. 'l and B, the upper part of the bar being ilat, while a ate the type bar carrying the star. There is also a middle key in the second row which is used soleinafter described. 'and does not have any type associated with it. The keys at the left ofl these two rows are intended to be manipulated by the fingers of the left hand, While those at the right are intended to be manipulated by the fingers of the right hand. f

Four vowel keys 6I are also provided in front of .the other two rows of keys at the center of the machine and are to be` operated by the thumbs.

The keys may have the characters printed on them, as indicated in Fig, 1, or they maybe left entirely blank to depend on manipulation by the y touch system.

`The keys are associatedwith type bar actuat-

v ing members

62, 15, and 3| which are bestshown.

in Fig. 8. .These members are substantially alike although some of them are mounted inone posi-v tion while others are reversed. The members normally are aligned in the machine and each moves downwardly when its associated key is depressed.4 In Fig. 8 two of the keys are shown de- 5:

an elongated base portion 6'3 and an upwardly 10 and forwardly extending arm 84 which supports the key at the top. 'Ihis member 62 is mounted for substantially straight-line vertical movement in the frame of themachine by means of two Vlevers 65 and 66. The lever 65 has one end piv- 45 oted at 51 to the upper portion of the member 66 while itsother end is pivotally mounted on the rod I6. The lever 5t has one end pivotally connected at 6B to about the center of the lower por- 'tion of the memberl es, while its other end is piv- 20 oted on the rod Il. The pivot point 68 is spaced I below the pivot point @l andslightly to the rear of it.

When the key is depressed both levers tand $6 move downwardly about the rods I6 and I1\ 25 and the type bar atuaiing member s2 wiil also move downwardly with substantiallystraight line motion. The angie' of the key surface, therefore, remains substantially the same.

Various means Amay be employed to transmit motion fromthe members 62 to the type bars. In the embodiment of the invention illustrated a finger 69 is provided extending downwardly from the lower edge 63 of the member 62, and this nger is positioned at such a point along the edge that it will engage with a cam slot 1B (Figs. 4 and 1l) in the particular type bar which that key is designed to operate. As illustrated in Fig. 8, the finger G9 on the key Se at the extreme left of the foremost row of keys'is arranged to operate the 40 second type bar from the front when the actuating' member $2 moves downwardly so that the iinger can engage the slot in the type bar;l The type bar slot 1li (Figs. 4 and 11)V is designed so as to cause rapid movement of the type bar in the 4a,

direction of the platen when the nger is ,pressed down into it, and then to slow up in its movement towards the platen, whereupon the force against 4the platen is increased .by the f urther movement of the nger.

The keys -in the rearmost row are supported on a, reversed type bar actuating member15, which is like the member 62,` except thatthe upper portion 16 extends rearwardly instead of forwardly.

This member 15 is supported on two 4levers 11 and l55 of can push the type bar towards the left without movement of the type bar actuating mem- 66, the former being pivoted on the rod I6i with its other end pivoted Iitt-19 to the member 15, while the latteris pivoted onthe rod I1 and has its other end pivoted at 80 to the center of the lower portion of the member 15. The movement which is supported between the end plates I2 and I I3 by attaching to suitable ii-IlgesV 55 and 51 of the

members

62 and 15 connected respectively to one'of the'keys 60' in the foremost row ,and one of the' keys 60 in the rear row is substantially the same when the keys are depressed, the downwardly extending fingers on both members 62 65 and 15 engaging the cam slotsV in the type bars 32 which the keys are'designed toactuate. The member 15 in Fig. 8 .is attached to the extreme f left key on the upper row of keys 60, and the finger 69* shown on that member engages the 70 foremost vtype bar 32. The mounting of the vowel .keys 6I is slightly diierent, although the principle is practically the same. The type baractuating members 8l fox-'the vowel keys are similar in shape to the members 62 except that they do not extend up-as far, since the keys 6I arel supported on the extending for- 'ward ends of levers 82 which serve the same purpose as the levers 65, connected to the type bar actuating members 62, and are pivoted on the rod I6 with their center portions pivoted at 83 to the upper ends of the members 5l.v The central low'er portion-of each of the members 8j is pivoted to one vof the levers 65. By depressing one of the keys 5I, the associated lever 52 swings about the rod I6 and the member 8i connected to it-moves downwadlytogether with the lever 66 which maintains the member 8l in substantially straight line motion.

When the pressure is removed from the keys 60 and 6|the members S2, 15, and BI arel raised again to theirv normal upper position by means of springs 8d which are connected'between forwardly extended ends of the levers 66 and the spacing rod i5. In order to secure the lower ends of these springs, the spacing rod i5 is provided with slots 86 spaced across the upper surface of the bar and a slender rod B1 is fitted into a longitudinal slot which ,extends the entire length oi the rod 'I5 and across the slots 85. The slender rod 81 is held in position by tamping the edges. Y

of the slot in which it is inserted. Each of the l springs Bd has its lower end looped around'the slender rod. A

The two rows of keys G0 are spaced at approximately equal intervals from side to side of the machine, and this means that the

levers

65, 11, and 66 which support the type' bar actuating members associated with these keys are substantially equally spaced along the rods I5 and I1.

The vowel keys 6i, however, are also supported in a similar mannenand therefore the levers E2 and 6B which support these keys comebetween the others ontne rods is and n. The spacing is maintained on therod l5 by means of sleeves 88 which are secured to the rod le by any suitablemeans. In like manner the levers 56 on'the I rod i1 are spaced by means of the sleeves 89 which are also secured to the rod I1 in any. i

suitable manner. The type

bar actuatng members

62, 15, and BI' have relatively large bearing 4surfaces with the levers which support them, and in all cases the

pivots

61, 68, 19, 80, and 33 hold these parts in close contact with each other to` prevent sidewise movement of the keys. also,l

the sleeves 88y and 89 support theflevers on the rods I6 and I1 respectively so as to prevent sidewise motion. This insures that each type barV actuating member will move straight down, .so that the operating nger on the lower edge thereber in the opposite direction.

`The return of the keys to their normal position I is cushioned by means of a channel member ,55

with

screws

88 and 95. This channel 95 conmins a, feit pad ma which is engaged by uieupper surface ot the type bar actuating members' 62, 151, andl 8l. If desired a pad III of rubber or other'suitable resilient materialmay be provided on the upper surfaoegof the channel membersoasto forma cushioneddownward limit of movement of thekeysand associated mechanism. As shovn in Fig. '8. this cushioning surface will be struck by the levers 65, 11', and

- of movement;

paper strip is caused to move the proper-distance through the machine sov that the printed char- 7 acts appear on successive lines on the paper.

For this purpose every one of the keys isv caused to operate the feeding mechanism, so that regardless of which key is depressedalone or what group of keys is depressed, the paper strip will always advancev the proper distance. In order' The shaft is positioned at the rear of the machine beneath the spacing and pivoting rod '|6, and the bail extends forwardly -so 'that its normal posi; tion is beneath the rear corners of the type bar The lowermost corners of these members are curved` as indicated at |04 in Fig. 8 so that when .these type bar actuating membersmove downwardly they strike the bail |02, causing the .shaft |03 to rotate in a clockwise direction, as seen in Fig. 8. The rear ends of the type bar actuating members slide over the edge of the bail |02, so

as to turn the bail to its lowermost position and hold it in that position before the type bar. actuating members have reached their lower limit 'I'he left hand end of the bail |02 isbent at right angles to form a lug |06 which is provided with a hole |06 adapted to receive a pin -'|0'|. This pin is rigidly secured to a short auxiliary shaft |08 which is. rotatably mounted parallel with the left end plate l2 between the arm 26 on a shaft |33 rotatably supported in a bracket |34. This bracket has downwardly extending -side arms |35 which are pivotally mounted on the shaft 126, A spring |36 which is wrapped' aroundl the shaft |26 causes the bracket |84 to 1 be' urged in the direction of the platen so as to maintain the roher |32 in contact with the platen. The bracket |34 iS. however, mo'vable away from they platen against the tension of the spring |30, so as to permit the insertion of the paper. rA lug .|31 is provided on one of the arms |35 of the bracket |34 which engages the outer end of the plate |29 so as to raise the outer end when the,

bracket |34 is moved downwardly,- and this separates vthe inner end of the plate |29' from the` platen so as to permit thevend'of the paper strip `to be slipped between it and the platen when inserting. The lower edge of the bracket |34 is provided with sharpened teeth |38 to permit the paper to' be easily torn ofi. against this edge when it isl desired to remove a section of the paper. An apron |39, supported between thetwo 1118s ,|21 and |28 on the arms 28 and 21 respectively,

separates the outgoing end of the paper 4framthe l' incoming portion.

It will `be seen that with the paper feeding mechanism just described, the platen will be turn'ed to move the paper strip in the machine whenever one or more of the keys is depressed.v However, the arrangement is such that the feeding mechanism will stop before the types have reached the platen. This is caused by the type bar engaging members4 passing over theedge of the paper feed bail before` the keys have reached and a bracket-|09 secured to Athe plate I2 by means of screws ||0. At the rear end of 4the their limit of movement. The movement of the paper thus stops while the types continue to move towards the platenand when the types strike, the

, paper is stationary.

The end of the lever is connected'by means of a link ||2 to a pawl 3 which is mounted vfor. movement about the platen shaft .29 on-an arm ||4. 'I he pawl is pivoted to the member ||4 at ||5. The pawl engages a ratchetl any one or more of the keys, the pin ,I 01, engaged by the hole |06 in the lug |05, will cause the shaft |08 to rotate in a; direction to swing the lever upwardly, thereby raising thelink ||2 and causing the pawl I|3 torotate the platen 28 through an angle corresponding to one tooth of the ratchet wheel ||6.V The bail |02 is. raised to its normal position after the pressure on the key or keys is removed by a spring |l'| which is attached to a pin ||8 extending outwardly from a lug ||0 formed on the right hand end of the bail,as viewed in Fig. 3.

Alevers

65 and 66. The member |4| is similar to the type bar actuating member 62 except that there is no finger extending downwardly from it, as indicated in Fig. 4, andv hence none of the type 4bars are actuated. by it. 'I'he member |4I,

however, does pushthe feeding bail |02 when it is depressed, just a's all of the type bar actuating members do, and hence when the key |40 is depressed, the platen is caused to rotate one notch of the ratchet wheel H6.

In the machine used for illustrating invention, the shift key |46 is intended to be used when it is desired to print numerals. Therefore, thelowerf' row of types 49 (Fig. 2) are arranged as follows from front to back of the machine: l

on the arms 26 and 21 respectively. The shaft bears resiliently against the platen 28.

-At the upper surface of 'the platen 28, Ipro.

vide a,v smallguide roller |32 which is mounted.

Since there are 11 keys across` the keyboard, the extra one may be-usedv to produce some other desired character'designation, such as the paragraph mark shown. Only those type bars which are associated with the rearmost row of keys 60 are provided with the lower types 49, the other -type bars having no lower'types thereon.

plates |46 and |41 mounted at the rear of the' The key4 |46' machine for vertical movement. extends the entire width of the keyboard and is placed just at the rear of the rearmost row of,

keys 60, so that it may be depressed with any one or more of the keys 60. Both plates |46 and |41 y are provided at their lowermost ends with slots |48 and |49 respectively in which :Bts the lowermost spacing rod I4, suitable slots being provided in that rod to accommodate the plates |46 8 'and |41, so as to permit vertical longitudinal vmovement but to maintain the plates in their proper position in the machine. The upper ends of the plates |46 and |41 are provided respectively with Slots |50 and |5|` (Figs. 3, 7, and 8) l0l which are adaptedto fit over the upper spacing rod |6,.suitable spacers being left between the sleeves 88 ofthis bar to accommodate the plates |46 and |41. These slots |50 and |5| are curved so that when the key |45v is depressed, it will foll5' low the movement of any key in the rearmost row. T'his avoids any chance of pinching the fingers between the elongated key |45 and any of the keys of the rearmost row which may be depressed with it. l

to clear the arm 26 and the arm' and link H2 slotted ymember |15 which is part of a .bracket 50 |16 used for supporting a. part of the ribbon mechanism which Will'be later described.

A lug |11 (Fig. 6) extending forwardly from thel upper extension |68 of the plate 44 `is provided with a spring |18, the lower end of which is at- 55 tached to a lug |19 o n the felt cushioning channel 95. The spring tends to urge the plate 44 normally downwardly, but upon depressing theelongated key |45, the arm |59 is rotated about the screw |6|, so as to raise the plate 44, which 70 l in turn raises the type bars 32, bringing the lower" row of types 49 into alignment with the platen and causing them to print onthe paper when the keys are depressed so as to move the type bars longitudinally towards the platen.

The members |61 65 The shift key |45, when operated alone, merely shifts the position of the left handends of the type bars to place the lowermost row of types in position for printing. However, when any one or moreof the rear row of keys 60 is depressed with the shift key |45, the type bars are first shifted and then the type bar's associated with the depressed keys are moved against the platen to print. The arrangement of the parts is such that the shift mechanism completes its movement loefore the types strike the platen.

The returnof the key |46 and plate 44 to their normal positions after the pressure is removed from the key is cushioned by means of a rearwardly extending ange (Figs. 2 and 9) on the arm |59. This arm is arranged to strike against a felt pad |8| provided in a bracket |82 held against the inside ofthe plate |2 by means the type bars move through the greatest distance to reach the shifted position. 'This means that the keys will not have .to be depressed as far to cau-se thetype bars to print as when the type bars 'are in their normal position. However, this dierence 'in movement of. the keys does not interfere with the operation thereof.P

Any type of inked ribbon may be used with the machine o'f the invention and any ty'pe of feeding mechanism may be used for advancing the ribbon between the types and platen as the machine is operated. In order to illustrate the invention, I have shown a continuous ribbon'50 which is arranged to move around the frame of the machine and to be driven by the' paper reed mechanism. To this end a roller |86 (Figs. 1, l2, and 6) The arm |59 extends through 40 ,|88 which contacts with the ribbon and which absorbs ink supplied to it so as to keep the ribbon moistened with ink as it passes over the roller.

The roller is mounted so that the left side of the pad |88 is aligned with the space between the platen andthe types when the types are in their normal position, so that the ribbon can move Without touching the types or platen.` At the rear of the machine, I provide an idler roller |89 (Figs. 2 and 9) lwhich is rotatably mounted on a bracket '|90 (Figs. '2 and 5) attached to the arm 26. Another idler roller |9| (Figs. 2 and 6) is rotatably mounted between the lower edge of the arm 26 and a bracket |92 which is provided for that purpose and is attached to the -end plate I2. This permits the ribbon to pass around the rear of the plate 2, as is indicated in Fig. 2.

I also provide a tensioning device for the ribbon which is mounted on a bracket |93 (Figs. 1,

2, 3. and 9) attached in any suitable manner tothe -lower space rod I4. A rearwardly extending flange |94 on the bracket carries an idler roller |95 on the right end of the bracket, while another rearwardly extending ange |96 on thel left .end of lthe bracket carries a depending idler roller |91.,` These'two rollers are 'aligned with each other and carry ilanges lto prevent the Aribbon from slipping oi of-them. A movable arm |98 is pivotally mounted'on the iiange |94 and carries a depending roller |99 at its outer end, the 4arm |98 being of sulcient size to swing within the- Y 1o flange |96, so that the roller' |99 will come be- Joperates that particular key.

in back ofthe roller |95, with the spring tending to pull the spring androller |98 away towards the front. This maintains a suitable tension on the ribbon at all times.

Another idler muer- .m (Figs. zy and 9) is 'ro` tatably mounted in a cut-out portion 2Min the endl plate I3, suitable guides 2lb being. provided above and below'the roller to prevent the `ribbon from slipping on of the roller. Additional rollers Ill, and 208, which are similar to the roller 2li; are mounted at the ends of flanges 3l, 3|, andV theforward end` of the end plate i3,

respectivelyno guide' the ribbonaround the right end of themachin'e. The ribbon extends from the roller-.20| back to the inking roller |86.

The ribbon is driven by driving the roller |86 4 from the. platen. To this end the roller; |86 is provided at its upper endl with a suitable gear,

I" (Fig. l) which meshes with a gear 2|0 carried by an auxiliaryshaft 2| A bevelgear 2|2 at tl'ieother end of theauxiliary shaft meshes with a bevel gear 2 3 on the platen shaft. At any 3 time that the platen rotates the ribbon roller |86 is rotated through this gear; connection. Since theplaten is always stationary when the types Y i strike, the ribbon will also be stationary.

The entire machine with the exception of the keys, and the platen, andpaper guide rollers may be enclosed in a casing 2 i 4 which may be attached to the end plates in any desired manner, as by supplying suitable flanges 2|5 'for thatpurpose.

'lhis casing is preferably made to conform as closely as possible to the configuration of the machine, so as to maintain the compact form, while ing across the machine. The consonant keys have ,a substantially straight lin'e motion so that they are easy to operate, and they. are also arranged so that two' keys in the same row from front to back of the machine may be operated sir'ultaneouslyby the same flnger.- The shift key can' also be operatedsimultaneously with 'any of the keys ofthe rear row with the same finger that Attention is again drawn to the fact that the order of the keys is independent of the 'arrangement of types from end to endof the platen. All of the type bar actuating members associated with the keys cross all of the type bars and hence any key on` the keyboard may be made to op,

ersteany type bar by providing-the finger 69 in the proper position above that particulartype bar and providing that particular type bar with a cam slot to cause the bar to move longitudinally when the finger passes downlnto the slot. For this reason, it is possible to arrange the order of the types from end to end of the platen. 'so as to print the particular I code which the machine is designed to use, and at the same time to arrange Y the keyboard with the keys in the most convenient 5 order for fast operation. Thus, letters or syllables -which are used. most frequently can be printed with the most convenient placing of the lingers on the keys.

Since certain changes 'may be made in' the 10 above construction and different embodiments of the invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shownvin the accompanying' drawings shall be .i5 interpreted as iiiustrative and not in s limiting Sense.
