PHILIPPE DE o AaIEoY, or oHARLEs'rown, MASSACHUSETTS, ASSIGNOR TO CORONA.

TYPEWRITER YORK.

To all wh om it may concern:

.Be-it known that I, PHIILIPPE,DIEI CLA- MnoY, atcitizen of: the United States, and residing in Charlestown, connty'of Sufi'olk, and State of Massachusetts, have invented certain new and useful Improvements in- Foldable Type-.Writ ing-Machines, of which the following is a full, clear, and-'exact -description.

One of the principal objects of this invention is to provide a typewriting-machine with a keyboard wherein the key bars are arranged for a lateral swinging movement to bring said. bars substantially parallelv with the axis of the platen, in order to make the 'm'achinemore compact. I

,"Another object of the invention is to-provide a, keyboard wherein the key bars may be divided into two groups separating along the central line of. the machine, one group being arranged to swing toward the left and the other toward the right to bring the key bar's into' a position substantially parallel 'with the aX-isof the platen, to make the ma chine more compact.

- A further object of the invention is to provide. means whereb I upon moving the key bars into their fol ed position substan q tially parallel with the axis 'of the platen,

t e platen carriage will bemoved forwardly, whereby the length of the machine fore and rearwill be very materially reduced and the machine made more compact. .There are other ob]ects of the invention which will appear more fully hereinafter, all

- of them. however, resulting in a typewriting i and storage.

. The machine when folded, is adapted tobe contained within a rectangular box, c0mposed of the base section a, the front section b hinged to the forward edge of the base section, and a partial cover section 0 hingedv to the upper edge of the front section. The front section is adapted to be folded down into the: sameihorizontal plane as the base section and to form a portion of the base of the machine when it is extended into operative position. The parts of the cover maybe folded under the front section b, as illustrated in Fig. 2, or it may be permitted COMPANY, INC., OF GROTON, NEW YORK, CORPORATION NEW 7 to remain in the same horizontal plane with 1 the said front section and with the base section, if desired. To the'rear edge of the base section is hinged a two part rear section d and e, said'parts being hinged together at f. The part 03 is adapted to fold down into the plane of the base and to form a portion of said base when the machine is in its extended position, as illustrated in Fig. 2. To

theupper edge of the rear sectione hinged a top section a which section may be folded understood that there are side sections which,

I j combined with the other parts ofthe inclosing box, as describedherein, completely in- "close the mechanism when in its folded and compact position. v p The keyboard is made .up of key bars 1,

which carry at their forward ends, the, usual u standin he s. Each key bar passes" p g y and there-ens Q im veFo through; a vertically slotted post 2, and is pivoted at its rear end to the forward end 3 "of the type bar operating link 4. The rear I end of thislink is connected to the forwardly extending 'arm' 5 of a bell crank lever 6, the

upper end of said lever being slotted at? to receive a pin 8 on the lower end of a V61; 'ticallyarranged type-bar 9. Th1stypebarf machine, the post 2? of: said group-"being mounted on ranged in two groups A and B, the outer post 2 of group A bem arranged to move 1n the slot20 at ther'ig t hand slde of the --ed'on't'he{left and lever 21, as shown clearly in};Fig.5 When the. levers 21 are moved 78 outwardly. Sand rearwardlyi to, the P08111011 oi i is tte nes F the links oser. relation,

I key 'ars swinging outwardlymr laterallywith the 'posts,l and finally assuming the osition shown in dotted lines in Fig. 6. en the levers 21 are brought forwardly into the full line position shown, ;in"Fig. -5, the links 15 are extended orswun outwardly away from.

d eachfother until- .te shoulders '17 abut tocarries the type block 10 at its upper en t and' is formed with a" forwardly extendin "guide arm 11. 'This guide annfits'an slides in aguid tube 12, in which is arranged acoil spring 13, said spring normally acting to draw the type barfto its rearward position, as" shown in Figs;, *2 and 3. The.

' type bar operatinglinktis pivoted on the bar 14.-

Each key barguidin'ggostQ is ivoted at its lower end to the en of lin s 15, the other ends of said links being pivoted together at 16 in the form of lazy tongs. The

forward ends of the links 15 are each provided with a forwardly projecting shoulder 17, said shoulders abutting together to limit the swinging movement of said links when the key bars are swung into their operative position, as illustrated in Figs. 1 and 6 of they drawings. The shoulders 17 insure the proper positioning of the key bars with respect to each other, while at the same time, permit said keys to be swung laterally to the right or to the left, as indicated in dotted lines in Fig. 6, the links 15 folding together as the links of a lazy tongs. The outer end links 15 are provided at their rear ends with headed pins 18 which fit and slide in a groove 19 in'the under side of the base a of the machine, as illustrated clearly in Figs. 16 and17 of the drawings. The pin 18 extends upwardly through a slot 20 in the base, so that the end post 2* carried by the end link 15 will be caused to move outwardly and rearwardly in the slot 20, as will,be hereinafter described. Mounted on the base of the machine are two forwardly extending levers 21, said levers being pivoted at 22, as shown clearly in Fig. 5.- To the forward portion of each of these levers is connected theinnermost posts 2*, the said forwardly projecting portions of the levers 21 being arranged at the center the. printing opera ether, thereby-locking the\links against urther separating movement. The headed pins of the posts 2 move forwardly and inwardly in. the slots 20430 the position shown in Figs. 4 and 5, thereb limiting the movement of the key. bars. t is therefore manifest that in order to collapse the keyboard and to bring the key bars intoa su .stantially parallel relation with the axis of the platen it is'only necessary to swlng outwardly and rearwardly the levers 21 to the position shown in Fig. 5.- The vertical slots in the posts 2 and 2 permitof the vertical movement of the key bars during the printing operation. The re h' are returned to their marten-tion after on .hy'gthe springs 13 andjb the unive Ybanasfwill be more fully ereihafter;described v The platen carriagefiii consists of a bed plate providedat its ends with ribs 24 which fit the slide in grooved supports andguides 25. These supports and guides are sectional,

. one part thereof bein'g mounted on the base a, the other part being carried by the por tion (1 of the rear wallof the box. When the machine is in its extended operative position the two portions of the guides are in the same horizontal plane'as indicated vin Figs. 5 and 8, and the carriage bed may then slide forwardly and rearwardly in said guides. The levers 21 are formed with rear-' wardly extending arms 26 which are connected by 'links'27 to the forward edge of the carriage bed, shown at 28 in Fig. 5. It is manifest that whenthe levers 21 are swung outwardl and rearwardly the links 27 and the clrriage bed will be drawn forward into the position shown in dotted lines in Fig. 5, so that the carriage is wholly supported on the base portion a of the in, closing frame when the machine is in itscompact or collapsed position. This frees are 1 and type bars the portion of the guides 25 which, are sup ported on the section at of theboxor frame,

- so thatsaid' portion may be swung upwardly into the pos tion shown inFig. 1 when it is desired to inclose the machine in'its box. On the carriage bedare secured-transversely extending guides or tracks'29, which aregrooved on their adjoining facesin order to receive the base 30 of. the platen carriage and 'to' guide it in its transverse movement across the machine; As shown in Fig. 8 of the drawings, the base 30 is supported in positionto move over the guides 25 in the lateral or transverse-travel of the carria e. Mounted on the upper sidelof the base of t ecarriage is a driving rack 31 with which engages a driving pimon 32, saidv pinion being drlven through a. spring drum 33 secured to the rear wall ofthe machine support. It

will,- of course, befunderstood that the car:

: riage may be driven, or moved transversely 'of the machine by any suitable means.

I 1 The platen 34 is journaled in the upper end. of vertically. arranged posts 35, said of horizontal rods 37 and posts beingprovided with ribs on their vertical edges adapted to fit andslide in vertical grooves in the standards 36 of the carriage.

The standards of the carriage base. The posts'3-5 are con- 36 are arranged near the ends nected together below the platen by a pair 7 37*, one of said bars beingdirectly over the. other, as indicated clearly in Fig. 1 of the drawings. At;- the outer end of'each group ofkeys'are ar ranged two platen shift keys 38 and 39, the keys 39 being arranged toextend through p the outer slotted posts 2*, asshown clearly in Fig. 1. These shift keys are pivoted at their rear ends at '40 to the forward ends of the shift levers 41 and 42, each of which is in turhpivoted on a bracket 43. The pivots 40 correspond to the pivots 3 of the key bars 41 are longer than the rear arms 42 of the and permit the shift keys to be swung later-- ally into parallel relation with the platen. The rear arms or members 41 ofthe levers levers 42 in order to provide for the two case movements orshifts of the platen. Connecting the rear ends-of the arms 41 and 42 with the transverserods 37 and 37 of the platen support are linked connections 44 and 45, 44 connectingthe rear ends of'the arms "41 to the upper rod 37 by means ofthe bell crank lever 46. The linked connection 45 connects the rear. end of the arms 42 with r the lower rod 37 as shown clearly in Figs. 1

and 2 of the drawings. The links which make up the connections 44" and 45 are formed with downwardly extending interlocking shoulders 47 so arranged that when the linked connections are raised through the shift keys-said shoulders abut'together and convert the linked connection into a substantially rigid bar which moves upwardly under the action of the key levers. The purpose of connecting the rear ends of the arms 41 and 42 'with the platen support by means ofthe linked-bars is to permit of the, fold ing of the parts, as will be hereinafter described. To permit the platen carriage to be [moved forwardly into the position shown in I Fig. 1, the platen must be bodily lifted in itssupport, in orde 1 to ermit the linked bars 44 and 45 to, be-swungrearwardly of the bars- 37, as shown clearly in Fig. 1. When the said bars have been moved rearwardly sufii-' ciently to permit the. carriage to be drawn into its forwardmost posltlon, the

platen may then'be dropped or lowered into,

.the position shown in Fig. 1. Whe n restoring the machine to itsoperative p'os1t1on,the

platen must first be lifted or raised inits supports to permit the linked connections to be restored to their operative positions, as shown in Fig. 2.

The paper guide 47 is carried by two grooved bars 48 which are rigidly connected to the innensides of. the platen supporting 6 posts 35. It will be, of course, understood that any suitable form of paper guide and support may be used.

The universal bar 49 is mounted on vertical rods 50 which are arranged in vertical posts 51, said universal bar overlying the shift levers and the type bars, as shown clearly in Fig. 1. Springs 52 maintain the I universal bar in its lowermost position'and.

the type bars and shift levers lift said unitending rearwardly therefrom are two arms- 56, said arms at their rear ends carrying the upwardly extending ribbon guide 57, said guide being pivoted on the end bar 58' which connects the rear ends of the arms 56. The

ribbon guide 57 is held in with relation to the platen which is coiled about the rod proper position 58, its ends engaging the ribbon guide, as clearly shown-in Fig. '15. 'It is manifest therefore, that the ribbon will be vertically vibrated through by a sprlng 59 a the movement of the universal bar. 'When; i theplaten carriage is moved forward through the operation of the levers 21 the ribbon guide willbe swung forwardly and downwardly by the rod 37 as clearly shown I inFig. 1.

Extending rearwardly from the cross bar I y M15 58 is a lug 60, on which is pivoted an escaperiage, means for supporting said carriage to permit it to have a vertical shift movement, a

shift key, a shift lever, the rear end of the shift key being pivoted to the forward end of the shift lever to permit it to be swung rearwardly and laterally to compact the machine, and means connecting the rear end of the shift lever with the platen carriage.
