185,708. Uriginal No. 1,222,550, dated April 10, 1917.
typewriting machines, and its primar ob )ect is to provide a practical and/e cient portable typewriting machine of the front strike or visible writing sort which is capable of being readily collapsed or closed into small compass, adapting it to be conveniently carried from place to place.
Other objects of the invention are to provide a small, compact, visible writing typewriter of comparatively inexpensive construction, whichis adapted to perform all of the functions required of the larger and Amore expensive up-to-date typewriters of the most approved design; to construct and arrange the various parts and devices of the machine so that the machine can be put in condition for Writing and colla sed, for transportation with thevminimum elay and inconvenience; and to improve typewriting machines in the several respects hereinafter described and set forth in the claims.
v These objects are accomplished by the novel` constructionl of the machine which,
briefly Stated, is as follows:
, The mainframe of the machine, or frame which supports the various operative parts of thet pewriter consists of ya lstationary section, ,rame or base which is adapted to rest on a supporting surface and on which are mounted-theftype bars, 'linger keys and .case shifting mechanism; and a movable'sec-- tion or frame which 1s mounted on the 'statona'ry frame so that it Scan be moved up and downrelative thereto andon which-'are rmounted the paper, carriage, together vwith the platen' andcarri'age actuating mecha- 'nisms, ,the .ipk ribbon andy its operating mechanismsand other parts'associated with f bar actions, showln `4 thev carriage. L0ne ofthe frames or frame ysect-ions lis ada tedto-surroundiand receive l,the otheigjan ,the parts mounted thereon are arranged lso that when'fthe machine co1lapsed,ipo r themovable :frame is lowered relatije the stationary'.frame, the .parts i thereof.
Application for reissue led Hay 24, 1918. Serial mounted on one frame will be received into spaces provided therefor -between the parts mounted on the` other frame. The parts which are carried by the movable frame are preferably disconnected from their actuating keys or devices which are mounted on the statlonary frame, so that in collapsing the machine it is not necessary to disconnect any parts or shift the operative parts from their normal position. v y

To enable this andjtof provide parts that accomplish all that'is required in a modern typewriting machine in a satisfactory manner, necessitated.l a novel construction and relative arrangement of the various' arts of the ma? chine,as hereinafter'descri ed.
A and A represent respectively 'the'base or-stationary section of the main frame and parts consists of a rigid substantially rectangular frame, provided with suitable lugs or parts for the attachment of the various operativeparts mounted thereon. The mo'vable frame is preferably larger than and surrounds the stationary frame'A and is pi'votally' connected thereto at its front end by.

The .studs-'1" a are rigidly seated in the sides of the'frame j for the 'movable frame A. When the machine /isshipped from the manufacturers, and when not'in use the movable frame is secured in the lower position Shown in Fig. 1, by screwing the thumb screws intothev lower holes a". To make ready for use it is only necessary to unscrewY the screws -from the lower holes, when the springs will raise Vthe movable frame, and preferably screw the screws into the upper holes al, and swing the 75 line space. lever hereinafter` described to the front.

vC represents the type bars which are pivotally mounted in any suitable manner in front of and below the carriage on a supporting segment Cf mounted on the stationary frame A. The type bars are arrangedto swing upwardly and rearwardly to the platen and each bar has three characters, the supporting segment bein .mounted on a shift frame which is mova le upwardly and downwardly vfrom an intermediate position for placing oneior another of the characters in printing relation with the platen. rlhe ent C is shown as secured by screws d toa shift frame D.
- The key actions for the type bars, as
" shown in Figs. 3, 4, 12 and'13,areformed of sheet metal stampings. The key stems c, c', c2, as clearly shown in Fig. 12, are made-in three different forms for the three banks ofkeys and have downwardly extending porf tions pierced for shouldered rivets by which they are pivotedyto the frontends of supporting levers c 0*, each stem being pivoted.y
to a air' of the levers. These levers .clvc are pivotally mounted, preferably infslots in the upper and lower edges of a fulcrum bar o which is rigidly connected atits ends in p any suitable manner `to the sides of the stationary frame. Th'e rear ends of the key levers c3 o* are connected by links c and c which are of two forms, as shown in Fig. 12.'
Certain of the key levers, preferably four at each end. of the keyboard, are connected by the links c and all of the remaining levens of the series are connected by the links c". The links c used at the ends of thel keyboard are madeof different shapes than the other links, so asnot -tojinterfere with other parts of the machine at'the sides thereof. The 'links c c'f-are connectedy to their respective type bars by long links cs, two'of which are shown in Fig. 5. These links are all of the same length and are preferably of inverted U-cross section and embrace the parts 'to which they are pivotally connected at their ends.` The links cs at the center of the series are curved, as shown in Figs. 3- and 13, so as not to strike the type bar basket when the segmentis in its lower 4shifted pos sition, but the .remaining links may be straight, if desired. The links c are made alike, each with four rivet holes, so this forml of link canbe used for either of eight differentplaces, butfas there is very littlefdifference inthe elevation of `'tlm front ends` f of the linkagea `where they.; connectto-jthe linkse, there is not suilicientrooni to" make these links .with livfet holes" for vall connec-j -tions With'the'.- linksc. l' Thelnks c are Y, made with the lowerm'ost holes, and,vv 'the other ,holes r'equired'forY connection to the several llinks a y are made at the properl f height of the machine. f x
points .in the several" links. The type bars` and key actions are returned Vto the normal positions by springs c c1 which are v attached to the-lower key levers c* and to the front bar of the frame A, preferably by the heads of 'screws acting as clamps. The springs with the exception of4 one` 01 are secured to the under side of the front bar l yof the stationary frame, the spring 01 being secured. to Athe upper side of the .bar t0.
,make rooml to actuate one of the center actions. V
It will be observed that the keys for the three banks are all connected kto the levers v3 c* which are fulerumed on the bar 0.
lThis bar with the two fulcrum wires for the n, levers extends the full length-.of the keyboard and is the only part of the key action after explained, also supports the space key, andas t e other parts are allstampings, the complete action can be Vmade at alow cost.
`As indicated in Fig; 5, except for av few of v the links at the center of the series, the links [cs diverge forwardly from thetype bar owing to the greater length" of the vkeyboard thanlof the segment, and theflinks c6107 are indicated as bent vinl rear of., ythe key 'that-requires machining. kThis bar, as here-A levers@3 fc" to extend. in the vdirection of the links o8. 3 The same result, of a direct pull on they links es could be obtained by bending the su porting key leverslc? c* in. rear of ,y their ulcrums.

one side of the frame A. The lowerends of these levers, see Figs. 3 and 4, are provided on a side of the shift frame to move it up and down from its normal intermediate position yshown in the drawings. The shift levers are returned after movement up or down to the intermediate position by springs d d which are connected 'to the shift levers and are anchored at their front ends by adjusting eye bolts to the lug d. .The lug d* limits the return of the-shift levers to the same normal position.` As seen in Fig. 4, each cam slot acts to move the' roller a certain distance 1n one direction and to forni a stop to hold it in normal position and prevent itsmovement in the opposite direction, and the springs d d1? actuate the cam levers to restore the roller and thejshift frame `to their central positions .w'hen the levers are released. The weight of` the shift frame is preferably balanced bya spring, not shown.
Y As shown inFig. 3, .the type .bar kseginei'it is located in a rearwardly inclined plane parallel with the line M, and the supporting links and arms .-:Eor the-shift. rameare pivoted'to the"sh iftiframe on line :v -m,
their front ends being'pivoted in ja rplane parallel with lthis line, so that when in either of its shifted positions the segment will be in the sameplan'e, and the action of the type bar will be thesain'e in oneposition as in the other.

A lever v movable frame A, the arrangement 'of the.
f), Fig. 4, fulcrumed on the lower pivot wire for the key levers is connected by a link f2 to the central arm f. A spring f? connecting the outer end of the lever f to the inner end of the arm f serves to hold the space key in its normal position and return it to this position'when releasedafter depression. f* represents an upright lever Awhich is pivoted between its' ends on a bracket secured to the center ofthe type-bar segment. The lower end of this lever is con-y nected by a linkor rod f5 to the rear end of the lever'f' and the upper end of the lever f* normally stands .just in front-of the uni; versa] bar E and extends hi l1 enou'ghfto strike the universal bar in all t ree positions of the shift frame and segment. y The act of .f depressing the space bar forces the upper rend of the lever f* against the universal bar and tripsthe escapement. `The space lever f* is supported by the stationaryl frame A, while the universal bar is mounted on the parts beingsuchvthat whenthe machineis collapsed the u-pperend of the space lever does not project above the plane of the'upper part of the platen. The leverl f4' and the parts connecting it. to the segment and s ace bar are omitted from' Fig. 3, wheret ey would naturally appear, in order not to complicate the figure and lobscure* other parts thereof. As indicated by the curved line y-y Fig. 3,l when the machine is col# lapsed t-he segment and rear end of the shiftV frame passnpwardly in front of the uni? vel-sal bar E without interference.

The escapementfwheel has a conical centralhole seated on the cone head of a shaft ga and is locked thereto by Yscrewing an inner com,v g4 up against thewheel. The opposing cone is formed integrallyl wlth the feed pinion g and this cone and pinion are locked tothe shaft by a jam nut and washer or other securing means. kA bearlngof any other suitable sort for the escapement wheel yescapement lever G is preferab and feed pinion couldbe emplo ed.

Figs. 11- and 16 show the lever in holdin position with the lever forced to the left' rightas seen in Fig. 16), and as soon as the lever is released from the tooth of the escapement wheel a sprin g6 acts to draw the lever to the right. T e object of this is to guard against the rengagement of the lever with the same. toot 0fl the wheel before the ycarriage driving spring -has overcome the inertia of the carriage and ,started the escapement wheel, as might happen 1n case a very light tensioned driving spring wasused,
H represents the rack bar with which the feed pinion meshes. The rack bar is made ofl a rectangular bar of substantially the length of the carriage ,with the rack teeth projecting downwardly from the forward portion of its lower edge. The front and rear faces of th ar are provided with opposable slots for-the reception of the margin and tabulator stops hereafter described. The ends ofthe rack bar are secured to the rear ends of supporting levers and h which are pivotally mountedon the o posite 'ends of the carriage. These levers pre erabl -have inwardly extendin j vare riveted in slots at t e endf the rack y bar.- The levers hand 71X arel 'pi'voted by screws k2 or otherwise to the ends of the rear ends whic carriage and are provided with slots'h concentric with their pivots in which screws or pins k, .attached tothe ends of the carriage, extend to limit the u and down movements of the rack bar. T e forward end of the lever h extends under the adjacent end of the platen shaft and upwardly and outwardly in front thereof in position to be engaged and actuated by the line space lever,
presently described. `A spring h5 connected to the lever h and to the adjacent end of the carriage acts to yieldingly hold the rack bar in the normal position shown, in which it meshes with the feed pinion.l
The line space lever preferably consists of an outer` or handle vportion I and an inner is connected by a hingejoint z' which permits the handle part to be swung forwardly into the operative position shown in Fig. 5 and indicated by broken lines in Fig. 1, or'to be folded inwardly in front of the platen when the machine is to be collapsed. This joint i is a'knuckle joint of any suitable sort which limitsthe outward movement of the handle part to prevent it from ybeing swung outwardly beyond the position shown in Fig. 5'
in which it is in line with the journal part.
A springt holds-the'handle-part'from accidental movement-from either position. The inner part I of the line space lever is jour- 115 journal portion to Which the handle portion l lever and .pawl are actuated to turn the line naled in a forwardly extending bearing-2 on the end of the carriage and is adapted to rock therein a llimited distance in opposite directions. At its rear end the lever part I is provided with a T-head which forms 1nwardly and outwardly 'projecting arms or parts i5 and'. A leaf spring i secured at its forward end to the bearing 2 rests at its free rear end on` the dat top of the cross head andacts to return the line space lever to the normal position when released after bein rocked in either direction. The han le part of the lever has a'down-turned front end adapted to be grasped by the lingers and is .provided at the upper end of this downturned portion with a projection i which forms a'rest forthe thumb 'of the Hand grasping the lever to facilitate rocking the lever. ,i7 represents an auxiliary lever or `pawl carrier `which is suitably pivoted at its front end in a lug on the inside of the bearing extension 2' of the end of the carriage and extends rearwardly beneath the platen shaft. A line space pawl s 1s pivoted at its lower end to the rear end of the auxiliary lever and is provided at its upper end with an inwardly projecting tooth or part adapted to enga e the teeth of aline space 'wheel i, secure to the adjacent end ofthe platen for turning thev latter. The inwardly projectingfa'rm i of the line space lever overhangs and is 4adapted to engage an anti-friction roller '19 suitably journ'aled on the auxiliary lever, lso that by rocking the line space lever to the left the auxiliary space wheel and platen. Aconcealed spring returns the auxiliary leverl and pawl to their .normal positions. 'Thepawl is pressed toward the line s ace wheel *byv aconcealed A spring. The ro ler 1 is of proper size to fill the space-'between the inner .face of the carriage end and the line space wheel and thus prevent lateral movement of the auxiliary lever. The line space pawl is provided 'at its upper end with an outwardly-project l mg part i adapted to ride over the curved rear edge of an adjusting and platen locking plate'12 which isarrangedagainst the inner face of. the. adjacent end of thefcarriage. This plate is made with an outwardly turned linger piece 13 at its upper end and with a spring -extension i, see Fig. 7 acting as a detent'which 'is adapted to-snap into either offour notches in the inner face ofthe end of the carriage concentric withv the platen shaft. The adjusting'late is provided ceny projecting-tubular trally with .an outwa flange which extends into an open lseat `in the end of thecarriage. andserves as a bearl ing for the platen shaft Thela e of the .plate -is open at 'oneside to permit t e platen shaft to be moved ndownwardly and upwardly into and out'of the bearing. The adjqsting plateis' secured tothe end of the carwheel and move it two line spaces if the line space lever is moved to the limit. When at the limit of its movement a rearwardly projecting part at the upper end of the pawl strikes the inner end of the screw or stop 16 on the end of the carriage, whereby the pawl is locked to the .line space wheel and prevents further movement ofeither the wheel or its actuating lever. If it is' desired to turn the line space wheel three spaces the adjusting plate is turned forwardly by its finger piece until the detent snaps into the next notch, and if but a single'space is desired, it is turned in the .opposite direction the corresponding distance. The position of the finger piece of the adjusting plate always indicates' the number of spaces adjusted for and the rear edgeof the adjusting plate holds the pawl outof contact with the Wheel when not in action so that the platen can be turned backwardly by means of the usual finger-.wheel at its ends.

and 2 is a center stop or abutment against which the margin stops are adapted to strike to limit the travel of the carriage in both directions. The margin stops straddle the rack bar having legs entering the slots in the front and rear faces of the bar, whereby the tudinall7 on thebar and each stop is provided with a spring clip n, the free end of which is adapted to snap, into notches n in the teeth fon the rear side of the bar to releasably retain the stop in position. The margin stops are, as usual, adjustable to different positions on the rack bar.
The center stop N2 is formed by a rearward projection on a lever n2, Fig. 14, which is pivoted between its ends to the upper end of an? upright lever n3. The lever u2 is located in a recess in the front side of the bracket e5 and the stop N2 projects from the lever rearwardly through a rectangular opening n* in f'the bracket with its rear end extendmg into the path of forwardlyprojecting portions of the margin stops. n
1s a spring connected to the outer end ofy the lever n2 and to the bracket e5 and acting to yieldingly hold the center stop N2 -in the positions own in Fig. 14, The opening n* in thel bracket permits the stop to move one letter space to the left (right in Fig. 14) after it intercepts the margin stop N, and after such movement to resist any furthermovement of the carriage. This movement of the stop N2 swings the upper end of the upright lever N3 `to the left and places Ithe-lower end of the lever over the rearwardly rojecting end of the arm e", connected to t e universal bar, and thus locks the universal bar and escapement from action, or locks the line, as. it is technically termed. By raising the rack bar until the margin stop N clears the center stop, the `spring' 11,5 will move the center stop back to lts normal position, and then by permitting the rack bar to resume its normal osition in mesh with the feed pinion, the line may be continued until the carriage reaches the end of its travel, if so desired. When the center stop N2 returns to the normal position, above mentioned, it will rest under the margin stop N and as the actuating spring h5 for the rack bar is ,stronger than the stop actuating spring n, the center stop will be `depressed by the marginstop into the lower part of the 'openin n4, but as soon as the carriage moves in eiter direction far enough for the margin stop to clear the center stop, the vlatter will return to its normal elevation. The forwardly rojecting part of the margin stop -N is ma e with an upwardly and outwardly are held from movement longistop. The other margin stop N is preferably made with a similar but oppositely inclined face, so that after this stop has been set for writing on the margin of the paper,
it, will not stop the carriage in its travel to the left.
O represents a main stop for tabulating,
which is adapted to intercept any one of a series of stops P- P which are adjustably placed on the rack bar, and as many of these. adjustable stops may be used as desired. The traveling stops shown are provided with legs which straddle the rack' bar in the notches therein and project upwardly from the rack bar. The main stop O'is so located that the rack bar has to be raised about twice as far when tabulating as for simply releasing the margin stops from `the center stop. This additional movement of the rack bar is made by rocking the line space lever I to a correspondingly greater distance. By
rocking the line space lever the proper distance to release the rackbar from the feed pinion, the carriage can be allowed to move to the left past the first or any desired number of the tabulator stops P yP .and the sel lected stop then caused to engage the main stop O to stop the carriage by giving the line space lever the. necessary additional movement to raise the rack bar tor-the limit of its upward movement; or by simply rocking the line space lever to its limit the first stop P on the rack bar will engage the main stop O. This construction thus provides for either the ordinary column stop, or selective stop systems of tabulating. Itis not so rapid as a selective stop system having a series of separate keys, but it accomplishes the purpose within a space that does not admit of a series of separate stop keys, and it does not require a carriage retarding device, thereby further economizing room.
The main tabulating stop O is rigidly connected to or'formed with a vplate q. which is v secured to the upper end ofthe bracket e5 by 110 screws g', Fig, 14, passing through inclined slots inthe plate. A' spring g2 connected to the plate g and to the bracket acts to retain the stop normally in the elevated position shown. When one of the adjustable tabulat- 115 ing stops strikes the stop Qthe stop plate is moved to the left and downwardly, so that the rackbar will, when the line space lever is released, rengage-the feed pinion before 'the adjustable stop is disengaged from the 1'20 soy mal feeding position. When the rack `bar is raised to release. the carriage a concealed spring swings the bell crank lever upwardly and a tooth on its lower arm enters between two adjacent teeth of the feed pinion and locks the pinion and carriage escapement from movement, so'that when the rack bar is released it will properly engage the feed pinion.
R represents the auxiliary carriage release lever which is pivoted on the left hand end of the carriage and is adapted to engage the rack supporting lever h. for lifting the rack to permit either margin rrstop to pass the center stop. A pin r, Fig. 10, limits the downward movement of the. auxiliary release lever, so that the rack cannot be raised by this lever high enough to cause the adjustable stops P P to engage the tabulating stop O. The auxiliary release lever will ordinarily be used to release the carriage or line lock, and the line spacing lever I will be used for tabulating.
S represents a carriage back setting lever. This lever, see Figs, 5 and '11, is pivoted between its ends to a lug on the under sidel of the rear cross bar of the movable frame.
Alv and its rear end projects loosely into a hole in one end of a bell crank lever s, Fig. 14, which is suitably pivoted on the rear portion ofthe frame A. Acspring s2 around the pivot bearing for this lever acts to yieldingly hold the back setting lever and connected parts in the normal position. s3 is a bar which is pivoted to the upper end of the lever .9 and is provided with a slot s4 near its opposite end through which extends a screw .95. 'which is seated in an upright brackets16 rigidly secured at its lower end tothe rear cross bar of the frame A. The bar 83 is adapted to slide on the screw 85. The bracket s6 is provided with a lateral extension formed with an inclined face, as shownin Fig. 5, adapted to force the inclined end-of the bar s? forwardly when the bar is moved inwardly by actuating the back setting lever. sf is a slide arranged on the bar 83 and retained thereon by the screw 85 and a screw s which passesgthrough a slot 819 in the. slide intoI the bar sa. The slide sa has a forwardly extending tooth at its inner end adapted to enter any one of the stop slots in the rear 'face of the rack 'bar H below the lower ends ofthe margin stops. f
A spring s connecting the slide s? tothe bar sa acts normally to hold the inner end of the shortI slot s in the Slide against thek screw la5, as indicated in Fig. 11. A leaf spring 812 secured to the bracket s6 and bearing at its free upper end against the vfront side ofthe slide ss tends to move the slide rearwardly to `disengage its tooth from the rack bar. Bearing in mind thatthe screw 85 is stationary and that the other screw a9 moves with the bar ast-he action of this device is as follows: The initial depression of the back setting lever moves the inclined inner end of the bar s3 against the inclined face of the bracket s6 and forces the tooth on the slide S8 into the slot of the rack bar which registers therewith, and the continued movement of the back setting lever S, the screw s being then located at the inner end of the long slot s19 in the slide, carries the rack bar and carriage along until both the slide ss and the bar s3 are stopped by the screws S5. The slots limit the movement of the carriage to about one-half .letter spaces, and as soon as this movement takes place the escapement lever G secures the escapement wheel one tooth backward from its former position. As the tooth on the slide ss is straight with a rounded end, it is locked to the rack bar so that it positively prevents the bar from further movement. As soon as the back 'setting lever S is released the spring s2 acts to restore the lever and 'the` bar s to their normal positions, and during the first part of this return movement the spring s pressing rearwardly on the slide se withdraws the tooth from engagement with the rack bar, and as soon as the tooth is clear from the rack bar the spring s1 restores the slide to its normal position. The back setting lever may be actuated as rapidly as des'ired and effects a single space backward movement of the carriage, and only one space movement, for each depression of the lever.
made of uniform width to fit the guide at three points, between and inwardly beyond the three typeor characters, so as to provide proper bearings for the type bars in the guide in the several printing positions of the segment.
The described collapsible construction of the' machine is such that when collapsed the machine is very thin or narrow in one direction. This is very desirable since it enables the machine to be contained in a I iarrow case which can be carried and handled much more conveniently than a wider or thicker case, even of smaller dimensions in other respects.
In the application the various ldevices and parts necessary to make a complet-e Vtypewriting. machine ca able -oi 'performing all of the functions o the modern typewriter have been illustrated and described, in order to show how all of these devices or parts can be arranged and cooperate in a' collapsible machine, andthe preferred construction of the various parts has been 'shown and described. It is not, however, thereby intended to restrict the invention to a machine equipped with all of these parts or devices, nor to the particular construction thereof speciiied. The claims for the relative arrangement of the various parts, whereby the machine can be collapsed into smaller compass, are not intended to be restricted to the described construction of the individual parts. On the other hand, the claims, made for the specific constructions of certain of the parts, are not necessarily limited to the use of these constructions in a collapsible machine.- Novel constructions for various parts of the machine, such for ini stance as key actions, the universal bar arrangement, the linel spacing mechanism, th'e carriage escapemeiit, the ribbon feeding and vibrating mechanisms, the anti-friction carriage guide track, the tabulating mechanism, the carriage back setting mechanism and the line locking mechanism have been described and shown in detail without making-specific claims therefor. But, the right,
is reserved to claim these various features in appropriate divisional applications-` It will be observed that one of the important features of this machine is that during the act of compacting as well as the act of extending the machine the operating elements carried by the movable member are not inverted or otherwise indirectly moved, but on the contrary are at all times maintained in their operative or upright positions; that is to say, while the elements `on each frame member are out of cooperative position with the elements of the other group when the machine is compacted, the elements of both groups are maintained 1n operative or non-inverted position.`
