i Application filed August 12, 1915. Serial No. 45,103.

To all whom 'it may concern.'

Beit known that I, JOHN H. BARR, citizen of the United States, and resident of the borough of Manhattan, city of New York, 1n the county of New York and State of New York, have invented certain new and useful Improvements in Type-Writin Machines, of which the following is a speci cation.

My invention relates to keyboard machnes and4 more particularly to typewriting machines.

One of the main objects of the invention is to produce a machine of the character speciied in which n contraction of the keyboard may be readily effected at will, 1n order to reduce the compass of the machine and thus facilitate packing and transporting or carryin the machine.

A further o ject of my invention is to provide n comparatively small, cheep and light. yet highly efficient, typewriting machine.

To the above und other ends which will hereinafter appear my invention consists in the features o construction, arrange monts of ports ond combinations of devices set forth in the following description and particularly pointed ont in the appended claims.

In the accompanying drawings wherein like reference characters indicate c0rresponding parts" in the various views,

l'n the various views parte have kbeen omitted, only so lnnch of the machine being illustrated as may be deen'led necessary to arrive nt an understanding of my invention.

Tile machine a whole is aso-called portable machine, being devised with a View to roviding a smell, cheap and light, yet higlily eflicient machine, which will do the work of o heaviei-hulkier and more expensive machine, and in which, moreover2 the keyboard may be readily contracted Within a small space close to or within` the frame, so that tho compass or dimensions of the machine is n whole ,may thnsbe still Vfurther rednccd and the machine received within a small, case of regular shape and proportions und easily carried 4or transported.

The moin frame is oblong in its eneral outline and practically all parts of vt ie ma chine. with the exception of the keys, are

contained within the general outline of the frame, and the keys, es indicated ahove, inayibecontracted within a comparatively Vsmall space adjacent to the frame, as illestrated in Fig. 2. i

The frame is `glesiggmited as a Whole b y the reference numeral Land comprises a ront cross plate or casting-2, side plates 3 and a. top plate 4. A cross bar 5 is Secured at its ends by screws to the side platee and rigidly unites the lutter neer the real-lof the machine.

A rotative platen 6 is supported by its shaft 7 {L1/bearing openingejiri brackets 8,

ico

i to, side plate 3 of the frame.

The latter are fixed to a substantiall C-shaped carri e member 9 formed wit race- Wa 8,10 r copbration with antifriction alle' or rlles 1. The balls 11 are likewise received in oeppositely disposed bearing grooves 12 form in a shift, "id'e orsup rti bar or r il 13 on -whic the carriage is sul'ip'ote'd or movement from side to side of the machine. The sup orting bar 13 for the carriwre is mounted fldr substaiitiull horizontala shifting movement fore iin( 'aft 'of th'e machine to change the case position of the platen, as will hereinafter more clearly appear.

For the pur 'ose of this invention any suitable paper 'ed mechanism may be emloyed; .In the present instance, I have shwn sheetl mtal combined paper table and apron 14 which extends beneath the laten between the brackets 8, and up to the ront of the platen where it is formed with bearings in whichva shaft 15 of a feed roller 16 is supported. The work sheet may, therefore, be introduced into the machine from the rear and beneath the platen, and will be directed around beneath and up and rearwardly over the top of the platen across the printing` line, suitable means not shown) eing employed to effect line spacing moveinents of 'the platen.

So far as the present invention is concerned', it is immaterial whether the platen be `givenv 'a case shifting movement or whether or not a relative case shifting movement-between the printing instrumentalities and the laten is effected. In the present instance, owever', I have shown a shifting platen, 'the means for supporting and shiftlng the' platen comprising `two sheet metal bracket a'rms 17 which extend forw-.irdlv and upwardly from beneaththe shift rail 13 at opposite sides of the machine, the shift, rail 'icing secured 'to andsupported by these bracket arms. The metal from which each bracket arm 17 is formed is bent at right ,angles to the plane of the bracket, to form a forwardly extending supporting member 18 substantially parallel with, and adjacent vEach sheet metal frame. fo1min; lr a combined bracket 17 and supporting member 18. has a pair of upright parallel links 19 pivotcd thereto at 20, one near the front and one near the real" of thc machine. The npp'cr ends of cach pair of links 19 are pivotcd t'o a side plate of the frame on pivot .screws Q1, the forward sel of links 19 h'eing united by and fixcdly connected with an intermediate rock shaft 2l. The platen i's thus supported and guided for the case shifting morcmcnt tore and aft ofthe machine. springs Q2 tending io ret urn the platen and thc parts roilmwzled therewith 1o and hold them in the normal position. and Shift keysE-S operating to .-hit't the platen rearwardly to the upper case position. The

i shift keys 23 are arranged at thc right and left-hand sides of the machine, cach key being provided with an L-shaped sheet metal stem 24 which extends through a slot in the front cross plate 2, and is riveted at 25 to an upwardly extending arm 25a on the associated carrying or shift frame 17--18. The shift mechanism is such that the platen., whenshifted from the full line to the dotted line position in Fig. 5, moves at the printing line substantially in an. inclined plane indicated by the dotted line :c in said figure. In other words, the platen moves from the lower to the upper case position upwardly andfrearwafrdly at a slight inclination, so thfA the extent of printing' movement of the type bars will be the same for upper case as for lower case writing, it being understood that the type bars move nearly but not quite throu h 1800 from the normal position shown in ig. 3 to the printing position shown in Fig. 5.

The carriage is driven by spring means (not shown) and, in the present instance, is controlled in its step-by-step letter feed movement by an escapement mechanism comprising a feed rack 26 'coperative with feed dogs 27 and 28. The feed rack is pivoted at Q9 to brackets 30 secured to the member 9 ofthe carriage. The rack is normally held in operative position for-coperation with the feed dogs by a spring 26, being limited in its movement under the power of the spring,r 26 by a finger 31 on the rack abutting the member 9 of the carriage. The rack, howeveigma be turned on its pivot 2t) in the opposite dviiection and against the power of the spring 26 by suitable releas-V ing mechanism (not shown) to release the rack from thenormally engaged dog 27. The feed dogs are mounted on a dog rocker one of the dogs being fixed to or formed as a part of the rocker, the other being. a loose dog' pivoted to" the rocker. The shaft of the dog rocker is pivote'd at 33 to bracket liio arms 34 which are `secured at their lower i ends Vto the bottom of .the shift rail 13.' The dog rocker is thus supported by ,the shift raih'whereas the feed rack is secured to the carrialgg'eand both the dog roc-ker and feed rack partake'of the case shifting movement of the 'carriage and platen. l

In the present instance, movement is transmitted to the escap'ement 'mechanism at l each printing operation by the following menns:-An arm 35 projects from and is fixed to the shaft of the dog rocker and carries a cylindrical crdss head or contact niember 36 at the free end thereof. dA frustoconical contact member 37 is fixed -to a sheet metal cross bar 38 secured at its ends bv rivets 39 to a curved universal bar -l-O. T11-ey cross bar 38 is provided with,depending` cars 41 pivoted at 4Q to crtlnkV arms i3. These crank .farms project from a rock shaft -tt which extends across the machine and i8 supported at its ends by bearing screws in the side plates of the frame. The univers l bar and the parte connected therewitlr" returned lo normal position by a spring whereas the dogr rocker is returned by a spring' lo". The universal bar bearsat the front .sido thereof against three guide lugs 45h formed on the forward edge of the ty )e har segment. A spring 45 tends to ho d the universal bar against the guide lugs 45" and prevent the universal bar from tilting on the pivots 4Q.

The same relation is maintained between the universal bar and the type bars irrespective of the case position of the platen, since the universal bar is not moved relavtively to the type bars when the platen is shifted. The extent of angular movement of the type bars is the same in printing upper case as in printing lower case by reason of the slight elevation given l'he platen when it is shifted to the 'upper case position. It follows, therefore, that the nni vers-al bar will be moved the saine distance by the type hars in either case position of the platen; However, the dog rocker and the parts carried thereby niove slightly up ward with the platen when the latter is shifted to thc upper case position. It is for this reason that the contact device 37 has its lower contact face inclined to correspond substantially to the inclined shift of` the platen, so that the relation between the feed dogs and the feed rack, and between the con` tact surfaces of the members B6 and 37, will remain the same inA either oaseposition of the platen and the' uniform movement of the universal bar will in either instance transmit the same extent i' of movemnet to the feed dogs.. flhis may better be appreciated when it sobserved that the incl1nation of the lower contact face of the member .37 corresponds to the inclination of the line w in Fig. 5, ory is arallel to said` line, so that as the member 6 shifts rearwardly and upward i with theplaten, the' position of theI univdrsal bar relatively to the type bars. and the `position of the dogs relatively to the feed rack is not disturbed, and the menif,

bers 36 and 37 are maintained in contact for transmission of movement from the universal bar to the feed dogs.

The construction illustrated in the present instance provides for the employment of thirty-eight type bars 46, each hai'inur two types thereon, and provides for the en'iliodinient of thirtvcight keys in the keyboard. f arranged and spaced as are the corresponding keys of the Universal or standard keyboard. The four keys for punctuation and special marks sometimes employed at the right-hand side` of the keyboard` `and ,the type bars controlled thereby. are omitted in the present construction. The type bara 46 normally rest :ainst a pl'dfi# and are pivot/ed on'a cur've I of each' bar being received in a saw-kerf 4B formed in ,a ent 49. A depending vflange 49* yis, formed on the segment below mi! polowhreof which ii kerfed to reeeve the'type'bars, inorder to'ntrengthen the segment at this portion ofiit. The type bars inther normal positions extend longitudinally in lines which radiate approx|- mately from the printing point, und each bar moves to its printing position through more than 90 'and approximately through 180. The pivot wire 47 is received in an opening in a bearingr portion 50 of the segment 49 and is arranged in an arc of which the printing point is approximately thc center, the actua center bein# slightly forward of the printing point. .he type bars are thus arranged to strike rearwardly and downwardly against the top face of ,the platen, the ty e bars moving in radial lanes. Geare connections' are provided tween each type har andeits actuating` means. Thus each type bar is provided at the heel thereof 'with a segmental rack 51 which is eccentric to the pivot of the bar, the distance of the rack teeth from the pivot being greater as the teeth approach the free end of the bar. centric rack 52 co-acts with the rack on each type bar, each rack 52 being carried by a sublever 53. These sub-levers are of a. uniform length and are pivoted on a pivot wire 54 and received in saw-kerfs 55 in a flange 56 on the segment 49. The pivot wire 54 is concentric with the pivot wire 47 and is sur ported in a bearing opening in the flange 56. The teeth of each rack 52 nearest the attached end of the sector are nearest the pivot of the associated slib-lever, the teeth being at gradually greater distances from the pivot of the sulrlever as the free end'of the sector is approached. It will be seen that the sub-levers 53 are levers of the first, order and are substantially.horizontally disposed. each sub-lever beinpVr located beneath its associated type bar and moving` in the same radial plane as the associated type bar. The

construction, in the present instance, is snch that each rack'fl engages. the rack on the companion type bar farthest from the pivot pivot wire 4T, the heel of the type bar when the parts are at nor- Ina-l position and gradually approaches the pivot of the bar as the har moves toward the printing` position. thus givingr a gradually accelerated inoven'ient to the type bar as it approaches the printing point. `This provides for an easy start of each type bar, the speed thereof increasingi as the ba r continues its movement-toward the printinp,r .point The se ent. 49 is provided with aterally exten i119.r arms 5'? formed with foot piecsl b. which the'segmentfmav he Secured" by'cre s 59 the sidgrplte of "180 the frame. .n will be understood 'am mesegmentalzrack 52. on each sub-lever 53 extends through, andis guided in its movement in,vthe'same saw-kerf 48 that receives the associated type bar. A wire spring 53 resses upwardly its freeend against the orward arm of each sub-lever 53, the rear ends of the springs being connected to the bottom of the segment 49. These springs return the type` actions to normal position.

The forward ends of the segmentally arrangedsub-levers 53 are disposed in a curve which is concentric with the pivot wires 5t and 47 so that the forward free ends of the sub-levers are nearer the rear of the machine as the sides of the 's stem are aproached. The forward en of each subever 53 is pivotally connected to a depend- A ing link 60, the lower end of which ispiv- Y printing movement of a ke lever is opery ative, therefore, to effect a 'irect' down pull oted to the forward end of a second sub-lever 61. 'The sub-levers 61 extend'fore and aft pf the machine and are pivoted at their forward ends in a straight line extending transversely of the machine on a pivot wire 62, the sub-levers being received and guided in sawlkerfs in the front plate 2 of the machine. The sub-levers 61 are pivoted to move in vertical fore and aft parallel planes and gradually increase in length from the center to the sides of the system, the rear ends of the sub-levers 6l terminating in an arc that corresponds substantially lto the are formed b the forward ends of the subdevers 53. l he construction and arrangement of the parts are such that the plane of movement of each of the sub-levers 61 intersects the converging plane of movement of the associated sub-lever 53. OtherwiseV stated the plane of movement of each sub-lever 61 is at an angle to theplane of movement of its associated sub-lever' 53 and this angle varies depending on the ositions of the sub-levers, the angular relation increasing from the center to the sides of the system. Each link 60, which connects an associated pair of sublevers, may eiect such cormection at approxu "imately the line of convergence of the planes of movement of said sub-levers, so that movement may be transmittedfrorn each sub1 lever 61 to its associated sub-lever 53 without side strain onV any of the parts. y

Each sub-.leverjlhas connected thereto,

intermediate its ends, aA depending-link 63 which extends downwardly to and is connected with a key lever of second order arranged direetl beneath and substantiall parallel with t 4e associated sub-lever 61.

on the associated link 63, the sub-lever 61 and link 60 irrespective of the position of the link 63 lengthwise. of the key lever and sub-lever 61. The links 63 for all rear bank of keys are connected to members vices.

naamw movement of the associated sub-lcver 61 although said sub-levers 61 and the key levers extend in opposite directions from theiil fulcrums. The other member 69 of each two-part lever is formed at its forward end with an upwardly extending ke stem 70 provided with a finger ke 71. ll'ach member 69 has a sheet meta strap 72 riveted thereto at 73, the strap being substantially Ushaped in cross section and surrounding at the looped portion thereof the other member 64 of the two-part key lever In a like manner the member 64 has a sheet metal strap 7l riveted thereto at arid surroundin the other member 69 of the two-part key ever. In this manner a sliding connection is pro vided between the members 64 and 69 ol each two-part key lever to enablethe key carrying members 69 to receive a rectilinear sliding movementl fore and aft of the ma chine on their companion members. A rearward displacement of the key bearing members causes the keys to be moved from operative positions in the keyboard, illustrated in Fig. 3, to a contracted relationship near the front plate of the` machine, and to positions where the keys of the several transverse rows are brought together and arran ed in overla ping positions as indicated'in gig. 2. It wil be seen that when thus positioned a single vertical 'transverse plane will cut all of the printing? keys, whereas when said keys are in their operative positions they occupy different rows which are in different vertical transverse planes. Each member 64 is provided with a downwardly projecting lug 76 on the lower edge thereof for coperation Withthe strap 72 on the companion member 69 in order to limit the forward movement of the latter. Y The members 69 vary in length depending on the position of keys carried thereby 4in the key-board Aof the ma chine. Thus, those' members 69 which carry the keys for the first orfront irow, are the received in the slots in the' guide confit but the forward end portion 64 of each' member 64 likewise extends throu'g'hav slot in the guide comb inorde'r to effectively guide the key levers in their pivotal movements. It will be 'understood' that the friction botween the straps 72 and 74 and the members LastnameY with which they teo-act is sutlicient. to maintain thevrsllding members of the key levers in the Positions to which they are moved; z'. e. cit 1er in their operative positions in the keyboard ot the machine or in the contracted relation illustrated in Fig. 2.

The two-part key leversy llereinbefore described are em loyed' for the lirst, vthree banks of keys, W ereas the key levers 77 for,

the fourth bank of keys, or that nearest the froment' ,the machine are constructed as represented in Fig. 8. Each lever 77 is preferably a single piece ke lever of the character shown; is provided7 with a finger key 78 and is connected at 79 to the asso- ,ciated ull link 63 by which connection is cffecte with the companion' sub-lever 61. Each key lever 77 is also providedwith an enlarged portion S0 which is received in a. guide opening in the front cross plateQ of the machine 1n order to effectively guide the key lever in its pivotal movement.- All of the key levers, both single piece and two part key levers, are pivotcd on the pivot rod or wire 65 and are received and guided in saw-kcrfs G6 in the cross bar 5` The levers 77 are made as sinfie piece keiY levers because it is unnecessary to shift the keys ofthis bank in the keyboard; they being as close to the frame of the machine as it is feasible to position them. derstood` however, that if deemed necessary the key levers carrying keys T8 may be formed as two-part key levers like those previously described.

I have provided means whereby the keyboard, by a single o'eration, may be collapsed and the keys rought into the'contracted relationship represented. in Fig. 2, or the keys may by a single operation be moved from the gmcffions ffnresentnd in Fig. 2 to their rvsgicctire operative positions in the keyboard of the machine, as illustrated in ligg. "t The ineen in :niceltion in the present inst-mirto comprises :i rectangular shoot met-nl l'l'annlit-sigimtcd as a whole by the reference numeral 81 and illustrated in detail in Fig. il. This frame is mounted like the two-part key lovers to receive a` slidin movement tore and aft of the machine an also to rewive a pivotal movement around the pivot rod (35. The rectangular frame comprises sido members Sii'orinr-d with a front cross bar Si bent4 over on itself to forni n space key R5. The side members 88 of llie frame have straps 86 riveter'l thereto al` Si", said straps being formed as a part. of a rear angular eros,l har 88 which conncfitae the sides of the traino nt the rear ends thereot'. Lever arms HQ are pivotcd on the rod tlf and nrturw-f-ivcd in the straps 86 on the frninol. [Cm-h lover arm hnsa strap90 riveted thereto at ill. tholooped portion ,of each A strap 90 surrounding the associated side bar Sil of tlnl rectangular traine, and affording a 1t will be umfore and aft sliding movement of the frame on the lever arms 89 and a pivotal movement with said arms. From an inspection of Figs. 2 and 3 it will be understood that thv rear edge of the space key 85 is adapted to oo-act with the key stems 70.01,, the Iirst two banks of keys, and Vwith rojections on the stems of the thir ban-k of keys, as the frame 81 slides rearwardly from the posit-ion indicated in Fig. 3 to that indicated inl Fig. 2. It will be understood, moreover, that the cross bar Slisin its rearward movement takes np the members (S9-of the first three rows of keys succb'ssively and moves them relatively to ech other, and at the termination of the rearward movement of the frame the body portions of the members 69 will be contained within the frame of the machine and the .keys will be grouped in overlapping posi-A tions beneath the last row of keys 78 and in the contracted relation shown in Fig. Q. At thistimethe rear ends of the sliding members 69 for the different banks of keys will he in a staggered relation, as illustrated in Fig. l0. ln this view l have shown one key lever for each of the first three banks of keys. When the rectangular frame 81 is moved forward from the position shown in Fig. 2 to that illustrated in Fig. 3, the cross bar 88 will coact. successively with the rear ends of the members 69 of the twopart levers (see Fig. 10) and will move said members forward nntil they are arrested by the logs 76. At this time the rear ends of all of the members 69 Will be alined .across the machine, as shown in Figs. 1 and 3, and the keys will have been brought to their respective positions in the keyboard of the machine, as illustrated in these figures. In thisy forward movement of the rectangular frame the cross har 88 will be brought sncrcssivcli into cooperation with the rear vnd ot' the members Gf) for the keys of the first thi-cc banks, the longest members 69 for the firs! bank ot keys being taken np first hy the cross bnr, the next longest members.

,for the second bank of keys being taken up next, and the shortest members for the third bank of keys being taken up last, and all of the keys, and the )arts which carry them, being; moved to t cir respective positions in the keyboard. of the machine by n single forward movement of the frame 81. When the keys are thus moved `to the separated or expanded relationship, and to thelr operalive positions in the keyboard, the rectangnlnr fran'le'is limited by the cooperation ot" its straps 86 with ings 92 formed on the lover arms 89, and the parts will appear :is re'gwesenfecl in Fi l and 3, the rear ends of all ot' the sliding members 69 being in intimement m'ljacent to the cross bar 88.

ThxA will odge of the front cross bar 84-85 is the ooh, fllectire portion thereof which is o erative on the key carrying members to shi them. From certain as ccts this may be regarded as a cross bar irrespective of whether or not it also carries a` space key or is extended forwardly fur enough to form a s ace key.

n order that a pivotal movement of the` space key 85 may bring about an operation of the escapement mechanism, operative connection between the space .key and the escapement is e'octed nby the following means:-

From ian inspection of Figs. -i and 9 it will be seen that a link D3 is connected at ,9i to ene-h of the lever arms St) so that the links do not interfere with the sliding movement of the frame 81. .Each link 93 is also connected to a bell crank lever 95 pivoted at 96 to a hanger 9T secured h v screws to a side plate of the machine. Suitable returning springs, as indicated at Je for example. may bey connected .to the bell crank levers toy return them and the parts connected therewith to normal position. Each bell crank lever 95 has a link 99 connected at oneend thereto, the opposite bent end 99 oi the link being received in a slot 100 in a crank arm 101. These crank arms project upwardly from the rock shaft 44 bywhich motion is transmitted to the` dogl rocker. lt will be seen that in the normal positions oi' the parts the Vbent ends.99 of the links 95) are bositioned in the forward ends of the slots 100, so that a depression of the space key is effective to rock the shaft 4i and actuatc the dog,v rocker. It. will also be understood that when the rock shaft il is actuated through the universal ber, by the movement of the type bar to the printing position, the arms 101 will be moved forwardly without transmitting movement to the links 99 and the space key connected therewith, a lost motion between the arms 101 and the links 99 taking place at this time. i

Any suitable ribbon mechanism muy be employed, only a part of one forni of such mechanism being shown 1n the present instance, in order to illustrate the general re-v lation of such mechanism to other parte of the machine. The crossbar v5 carries bracket arms 102 from which upwardly" extending ,spindles 1,03 pro'ect. Thesel spindles also project through caring openings in arms 10,4 forme/den th@ Segment 49- Ribbon spools 1.0,5 are su ported on the spindles 10,3 and are driven shown.4 The ribbon 106 extends'ecross the machine from one spool to the other, being threaded throughs suitable guide 107v by whichit is presented at theprinting point.

A Atype guide 1`D8 may be employed for co-opgration .with the type bars. This guido Vi@ formed as lfr part of armsV 109, which are s., to the segment 49 by screws 110.' .05

he Vconstruction and arrangement of the y suitable niechnnism, notmambo different. distances from the -fulerums of the ,i

sub-levers G1, and at dii'erent distances from the fulcrums of the key levers, depending on the lengths of the sub-levers' 61 andthe key levers which are connected 'by said links. I have attempted to illustrate this variation in the oints of connection of the link 63 Slt the le .t-hand side'of Fig. 1. In order to avoid confusion in the showing, I havel illustrated only five of the links (33; those which are connected to the key levers of the firstfive keys from the left in the first row or bank, and to the corresponding' sub-levers 61. It will he seen that these links are connected to their associated levers at gradually increasing distances from the front of the machine, and from the fulcruni or pivot rod 62,'as the left-hand side of the system is approached, and as the sub-levers (il become progressively longer. The points of connection of the links 63 are 4also determined by the lengths of the key levers, compensation being made for the variation -in the lengths of the key levers as well as the sub-lever 61. The difference in the 'points of `connection to compensate for the difference inlength ot'V the key levers is slight and' does not clearly appear in Fig. 1, since the links 63 there shown are all connected to key levers of the same length.
