Patented Sept. 2, 1919.

Ta all whom it may concem:

Be it known that I, PHILIPIE on LAMIJY, a citizen of the United States, and resident of the city of Boston, county of Suffolk, and State of Massachusetts, have invented certain new and useful Improvements in Type- Writin Machines, of which the following is a speci cation.

The main object of the invention is to provide a small, light-weight typewriting machine containing the usual roups of mecha nisms found in the accepte standard typewriting machine, and to simplify the construction of the machine and materially reduce the number of parts in order to reduce the cost of manufacture and to produce a small portable machine.

In the drawings, Figure 1 is a vertical sectional view taken fore and rear of the machine, the platen carriage and the platen bein shown in end elevation;

ig. 2 a detail transverse sectional view of the machine showing the universal bar and the means for operatmg said bar through the type bars;

Fig. 3 a detail view of one end of one type bar;

Fig. 4 a horizontal sectional view taken approximately on the line IVIV 01 Fig. 1, parts of the mechanism being omitted for the sake of clearness in illustration;

Fig. 5 a plan view of the machine;

Fig. 6 a vertical sectional view of the ma.- chine taken fore and rear of the machine, showin the platen shift means;

Fig.% a detail horizontal view of a part of the machine showing the ribbon vibrating means; and

Fig. 8 a detail side elevation of a portion of the ribbon vibrating means.

Referring to the various parts by numerals, 1 desi nates the main frame of the machine whic 1 is preferabl formed of soma light rigid material such as aluminum, said frame beiiig formed with a keyboard part 2, the ribbon-reel supporting parts 3, the type bar receiving portion 4 which lies be: tween the ribbon-reel supporting parts, and the rear part 5 which supports the carriage bed. The usual pivot wire 6 for the type bars eXtends transversely of the type bar' receivin portion of the main frame at the 1ear en thereof, and on said ivot wire the type ba-rs 7 are mounted.- aid bars nov mally extend forwardly from the pivot and are rovided with type heds 8 Which rest on t e type support 4 of the main trame, suitable cushioning means being.provided to receive the type when the return to their normal at-rest position. ounted on the keyboard frame part 2 are a series of up- Wardly extendin guide tubes 9, one tube being provided %or each of the type keys and the shift ke s, and one for each end of the space bar. 'he keyboard is preferably a standard or universal keyboard, but, of course, the keys may be arranged in env desired manner, one key being provided for eaoh type bar, in the usual manner. Mount ed t0 reciprocate vertically in each tube 9 is a finger key 10 having a stem 11 which fits closely in the tube. Connected to the lower end of each key tube 9 is a tubular guide 12 which is curved downwardly and orwardly at its lower end and opens into an enla1ged eup-shaped rigid guide 13 whieh inclines upwardly and rearwardly and is open at its rear end, as clearly shown in Fig. 1. Connected to the stem of the finger ke is a thin, flexible operating rod 14 which fits nicely in the guide tube 12, its rear end extending into the guide cup 13. This operating rod is preferably of material like piano wire, of small dia-metel, and fits nily in the tube 12 so as to be guided therein and prevented from buckling or twisting. Connected to the end of the operating rod within the guide cup 13 is a, type bar lmk 15, said link be1ng formed with an enlarged head 16 which fits normally against the forward closed end of the guide cup. The link 15 is connected at its upper rear end to the type bar adjacent the pivot thereof and in such position that when the link is forced marwardly by a clownward pressure of the fin r key the type bar Will be thrown upwar ly and rearwardly to the printing(}point on the platen. Mounted on a longitu inally movable slide 17 is a tension-adjusting bar 18 which extends u wardly and is a ertu'red for the passage 0 each of the type ar lin'ks 15, the said tension bar being aPranged a Suitable distance at the rear of the guide Cup 13. Arranged in aachuid e eup and bearing on the head 16 is a.sprmg l9, the rear end of said sprin beiring agamst the tension bar 18. Thma ed through the lower end of the tension har midwy the amis operated menus.

thereof un adjusting rod whose forward end projects through the front of the frame et the nmchine and is provided with an 01;;- emting lmob 21. By rotating the rod 90 t c tension bar 18 nmy be moved forwardly or reurwardly to. simultnneously v,ary the tension of the springs 19. By this means the touch of the keys nmy be made uniform and may be simply and rea,dilp, simultanconsly edjusted. As shown in t1e drawin 8, the tension ban is supported and guided y one slide 17 arranged midway the end-s of the bar. It will, of course, be undersbood that thetension bnr may be guided in other ways and that more than one slide 17 may be provided if found desirable. It is mamfest that the type bar action is very simple; is of few parts, and that there is only one pivotal connection between the type bar and the key- This construction elimimates lost motion, reduces the diificulty of assembling.thepats of the type ban: action; and the type bars are moved b 21 d1rect upward and reerwardthrust transrnitted from the-fingor keys though the opernting rod 14 a;nd the conneeting.link 15.

There1 ends =of the; type bars, beyond the oi*ot wire=6, are-formed 1nto up}wardlyand reawadly curved-cms 22. ach of the cams 22- bears on a relier 23, The rollers 23 are mountod upon a common bearing rod 24 which is carried -by auniversel bar 25 which extends:transvemelof the machine. The ends of theunivers&l bar arepro-vided with downwardly entending*- guide pins 26 which fitubfllanpost27mountd on the base of the main frame, said bar being maintained yieldingly in its uppor normal position by springs 28 arranged between the universel bar and the base of the frame. AS each type bar is thmwn upwardly through the keyaotuated menns its cam 22 depresses the univesahbar, and through themcvement of snid bar the several groups ofmechanisms ure operated, said groups inoludin the escapement means for controlling t e l'ettxer s ace mo-viement of the carriage; theribbon v1bmtor and the ribbon eeding means.

On the'main frame of the machine, in the reanofi*the*type basket, is mounted a carria.ge supPortiflg means or bed consisting of tlmcrflagatraaks 29 Which extend transvemelyofi the-machine at the top of the main framo and and connected together by dependingyokem 29. are:onmfid oppod horizontal ways 30 in whiuh:nre-ar&rmgstwesets of bearing halls 31L Theeanfiag is formed with longitudiand bear agaimsfr the other set of balls= 31, onet set of beaing balle supportingthe car rings wnd the other 5615 neceiWing thb forward and mar thrnSt theeof 'Ihe* carnistge is In the carriage tracks brackets 33, sait]. brackets being eonneeted togcther at their lower ends by 11 suitable base plate, and the track fianges 32 are formed along the forward and rear edges of said base plate. A printing platen 34 is provided with a suitnble supporting shuft whieh is journaled in the bmckets and cnrries ut its onde the nenni finger wheels 35 by which the pluton may be rotated. Suitably secured to the rear part 5 of the main frame in :L spring drum 36 in which is wound the usual motor spring for moving the carriage for latter space movement, said spring being connected to the carriage by any suitable form of baud, as indicated at 37 in Fig. 1. Mounted on the base plate of the a1riage, or formed inte rai therewith, is an escapement rack 38, an engaging said rwok is a doubletooth escapement dog 39 which is mounted on a vertical pivot 40 rigidly secured in the middle yoke 29 of the cai'ringe supporting frame. The dog 39 is engaged by a vertically extending vibrating lever 41, the lower end of wh=ich is connected to the universnl bar by a. link 42, said link extending upwa.rdly andforwardly to the universal bar &S"ShOWD clearly in Fig. 1. The dog 39 is formed With a horizontal yoke 39 in which is en%gadthe upper end of the lever 41; and t e lever 41 is in two parts which are vertically slidable on each other part being connected to the linl 41. The end omss*ba1s or yokes 29 of the carriage bed are provided With depending dove-tailed posts 01' slides 43 which fit corresponding slide-ways 44 formed on the sides of the frame 1. This permits the ca.rriage bed and the carringe to be verticnlly moved for the easeshift positions of the platen.

Upon the movement of a type bar to the printing position its cam 22 will depress the universel bar, as previously described, and carry downward the folward end of the link 42. This movement will cause the link 42to swing the lower end of the lever 41 rearwardly, thereby oscillating the escapement dog 39, thereby releasing one tooth of the do from the carriage rock and bringing the ot1el tooth into engagementtherewith; VVhen the type bar rerturns to its normal nttest position the springs 28 return the universl bar to its upper position and, throngh the link 42 and lever 41, reverse the movement of the escapement dog, thereby permitting thecaniage to move one latter spce under the influence of the carriage moving spring; The yoke 39" on the escapement dog pernnts the carriage to be shifted vertically without= disengagement between the cerriage dog*&nd its vibmting lever 41. The sliding connection between the lower section of the lever 41 and the upper section thereof permits a free rearWard movement of the lower end of the lever Hnder the action of the link 421 the lowef 111 the rem et the l'rznne directly below the loWer ends of the slide bars 43 is monnted a transverse rod 45. On this IOd adjacent each post 13 are mounced two eccentrics 46 and 47 of difierent diameters, the eecentric -l7 being of larger dinmeter than eccentric l6. Formod on the lower and of each slide porzt 13 is an inwardly extending foot 48 which is adapted to be engnged by the eccentrics, as shown clearly in Figs. 1 and 6. Connected to eccentric 47 is an operating aun: if). :m l connevtesl to eocentric 46 is an opernting urm 50, both of said arme extending t0 a suitable point above the eccentrics, as shoivn clearly in Figs. 1 and 6. Conneoted to the operating arme are forwardly oxtending links 51, said links being connccted at their front e2adg t0 flexible key bars 52 which slide in tubes 53 and are provided at their npper f0rward ends with fingor keys 54. The guide tubes 53 are rigidly secured in the rear onde of guide cnps 13 rigidly secnred to the cross-bar 13, and similar'to the cnps t0 whieh the guide tube-9 12 are se0ured. In said cup and heming on the tension bar 18 is a spring 55, said spring serVing to retnrn the operating keys and the connected eccentrics to their normal positions when the operating keys are released. The tension of the springs 55 will be adjnsted whenever the tension bar 18 is moved throngh the adjnsting rod 90. It is manifeet that by moving the finger kev connected to the eccentric 46 the conneared operating arm 50 Will be moved reerwardly and the eccentric so tnrned as to lift the carriage bed to its central caseshift position. It is also manifest that by operating the finger lre v connected to the shift eccentric 47 the carriage bed and the platen Will be moved to itnpper-case shift position. As shown in Fig. 4, tWo shift keye, With their connected eccentrics, are provided on each side of the keyboard.

Io look the platen in any one of its caseshiit positions a Wedge 56 is providd. said Wedge being arranged to be projected in between the foot 48 of the slide posts and the eeeentric engaged the1ewith. This wedge is connected to the rer end m" a link 57, sid link heing connected to a locking key 58 li 7 means of a flexible kev ber precieely as the eccontrio operating links 5] are connected to their finger keys. Te relense the carringe nil permit it to retnrn to its normal lower position f i*- only neoesenrv to give a elight npwnrd pull on the locking key. moves .+he wedge from lz etween the foot 4-8 and the engnged eccentric and permits tl1e mroentrie to be retnrned ro ite normal posifion.

Snpported on the machine trame. on oppoeitn eidee of the type basket, are. ribbon epoole 59. mid spools loeinn mounted on vertical spool shafts 60, said spools being se- This recnred to said shafts by means of thnmb nuts 61 screwed on the upper ends or' seid shnfte. The lower ends of these shafts, below the type basket, are provided with ratchet wheels 62 through which the ribbon spools are rotated. Connected to the universel bar and extending forwnrdly thereironn at each of its ends, are links 63. the Forwnrd ends of which are connected to levers 64-. On the free end of each of those levers pivotnlly secnred a cross hend 65 on the onde of which are monnted puwls 66 and 66. Connected to the ross head 65 and extending to the enter side of the machine frame is a slidable rod 67 on the end of which is secnred a finger piece or knob 68. By moving the 110d 67 ont wardly to the position shown in Fig. 4, the pawls 66 are brought into engagement With the ratchet wheels 62. By forcing the said rod inwardly the pawls 66 are released from the ratchet wheels and the pawls 66 bronght into engagement therewith. It is obvions that by depressing the universel bar the link 63 is forced forwardly. therebv swinging the levers 64 on their pivots. The rocking motion imparted to the levers 64 Will cause the pawls 66, when the parts are arranged as shown in Fig. 4, to rotate the rafchet wheels one tooth forea.ch operation of the nniversal bar and thereb v rotate the ribbon spools. It Will be noted thnt, as indicated by arrows in Figs. 4 and 5, one spool will rotate to take up the ribbon While the other ie rotating to let off. VVhen it is desired t0 reverse the travel of the ribbon it is only necessary to slide the bar 67 to releaso one F9i of pawls from the ratchet wheels and to bring the other set into communication therewilh. The pawls are provided With snirable springe to cause them to slip ovor and engage the teeth of the ratchet wheels; and the springg 28. in retnrning the universel bal to its normal position, Wlll serve to nlso retnrn the levers 64 and the pawls carried therehv t0 ilPl normal positions.

Monnted on the central yoke or bmeket 29 of the cerriage supporting bed is a. lever 69, said lever being mounted upon a horizontal tnbular pivot as shown clearlv in Fig. 7. This lever is in the form of a bellcrsink, having a shorter arm which extends downwardly and for-wardly, and a longer nrm 69 whirlu extends npwnrdly and forwardlv. The sa.id npwardly and forwardly extending arm 69 of said lever is provided with a longitudinally extending slot; and

embraeing said arm nt its upper and is a fork 70 Which carries ut its upper forward and the ribbon holder 71. Two pins extend throngh the arms of the fork 70 and throngh tl1e slo t in the mm 69; and a s.ring 752 connected to the fork and to t e. a1*m 69" normally holds the ribbon holder in its lowermost position, as shown ciearly in Fig. 1 of the drawings. The

lever 69 is provided with a rearwardl and downwardly extending slotted arm 3, in the slot of which is engaged a pin 74 carried by a vertically reciprocable bar 75. The lower end of this bar passes through a vertical guide 76 mounted on the upper end of a rod 77 whose lower end is ri idly fixed to the universel bar. It is man1fest that by depressing the universel bar the rod 75 will be drawn downwardly and the ribbon holder thrown upwardly and rearwardly to the printin point through the arm 73 and the lever 9. The ribbon holder pref erably extends forwardly and upward y at en angle which leaves the rinting oint on the platen visible except w en the 11 bon is thrown to the printing point. When the carriage is 1novecl upwardly for its difierent case positions the slot-and-pin connection between the rod 75 and the lever arm 73 will permit lever 69 to move upwardly with the onrriage bed, the lever 69 slightly el1an ing its angular relation to the carriage be for the upper-case positions. However, as the clownward movement of the rod 75 will swing the lever 69 on its pivot sufliciently to brmg the ribbon to the printing point, without regard to the vertical shift of the carria e bed, this sli ht change in the position 0 the lever 69 or the upper-case positions Will not be material.

In order to adapt the ribbon holder for biehrome ribbons or multiple-color ribbons, the fork of the ribbon holder is connected by a link 78 whose lower end is oonneeted t0 a crank arm 79 of a horizontal rotatable rod 80 which extends through the tubular pivot of the lever 69. The outer end of the rod 80 is provided with an upwardly extending crank arm 81 to which is connected the rear end of a link 82. The forward end of said link 82 is connected to a bell-erank lever 83 which is mounted upon a horizontal pivot and adapted to be moved throu h a vertically arranged fin er key 84. t is manifest from Fig. 1 0% the drawings that by depressing the key 84 the erank arm 79 will be thrown upwardly and the connected link 7 8 will be moved outwardly on the lever 69, thereby projectin the ribbon holder upwardly and forwar :y to brin a new por tienof theribb&n into the pat of the ty e bars et the printing oint on the platen. y this means a twoco or ribbon may be used. It is obvious that the finger key 84 may be provided with suitable stops or catches in order t0 seeure the ribbon holder in its adjusted positions. When the finger key 84 is released the spring 72 will retum the ribbon 'holder to its normal lower osition, as shown in:Fig; 1.

Mounted on the platen shaft is a line space lever 85 which carriese pawl86 adapted to engage a ratchet wheel 87 secured to=theehd o the placem Th e line spa lever is adaptet] t0 vibrate between luge 88 on one of the oarriage end brackets 33 t0 limit the rotation of the platen through the line space lever. It is o'bvious that by swinging the line space lever upwardly and rearwardly through the limit of its movement, the platen Will be r0 tated for lime spacing.

The paper feed roll 89 is provided with eceentric bearings 90 mounted in the end frames of the carriage. Pivotally connected to one of these eccentric bearings is an upwardly extending link 91 whose upper end 15 connected to the rear end of a paperreleese lever 92. It is obvious that by depressiug the forward end of the paper-releaso lever the paper feed roll Will be rotated'and withdrawn slightly from the platen t0 release the paper.

The carriage end frames or brackets are formed .with rearwardly extending luge 93 in which are pivoted the ends of a margin stop bar 94, said bar being proVided on its forward side with teeth 95 adapted to ha engaged by sprin s 96 carried -by adjustanle margin stops 9 Each stop is provided with a dependin stop finger 98 shown clearly in Fig. 1. %3y forcing forwardly the free ends of the springs 96 said springs Will be released from the notches of the stop bar and thestops may be then adjusted to any dsiredposition on said bar. Upon a release of the springs 96 the stops will be locked in their adjusted positions. Secured to the rear of the carria e bed is an adjustabie main stop 99, sai stop being ad;ustably connected to a suitable bar on the carriage bed by means of a Springpressed locking device 100. By drawing outwardly the said look devine 100 the main stop may be adjusted to any desired position on the car- .riage bed. To release the carriage stops from the main stop the stop bar is provided with an upwardly and rearwardly extending link 101 whose upper end is connected by a pimand-slot connection to the rear end of a stop-releasing lever 102 which is piv oted upon thesha t oct the platen. It is obvious that by depressing the forward end of the lever 102 the stop bal Will be rotated and the stops 98 swung reerwardly free of the main stop 99.

Suitable alarm meehanism is operated through the carriage, the carriage rack bar 38 being provided with a long vertical lug 103 on its rear face which is adapted t0 engage the upper end of a lever 104 which carries at its lower end the bell striking devioe. The lug 103 is adjustable along the rack bar in order to operate the bel] at any desired point.

A paper-finger supporting rod 105 is se cured to the forward edges of the carriage brackets 33, and on said rod are mounted the usual paper fingers 106.

A epaee ber 107 is=eonnaeted et each of its ends by means of a flexible push rod 108 and a rigid link 109, to a universal bar opcrating lever 110 which is provided with a cam 111 similar to the cams on the type bars, which cam is adapted to engage a relier on the univcrsal bar. The space bar ush rods are returned to their normal positions by means of a spring 19 precisely as described with respect to the type bar push rode. These tension springs are arranged to engage the tension bar 18 and to be adjusted thereby, precisely as described with respect to the type bar actions.

F rem the foregoing it is manifest that I provide a typewriting machine of very simple construction; of very few parts, and which is compact, light and of small dimensiens. The flexible pianwire o erating rods 14 and the links 15 constitute W at may be properly termed a flexible push rod, the portion 14 thereof readily flexing and conforming to the curvature of the guide 12 as the key is depressed, and the movement of said flexible rod resulting in a rearward and upward push or thrust on the link 15.
