To all lL-hofft it may concern:

Ain typewriting machines. one. object voi. the

invention being to 'produce a typewriter equip ed with a full size keyboard and a vcomp ete set of finger keys and type. such as empl ed in standard makes of typewriters but w ich is of unusually compact form an l isfadapted to be uickly and easily reduced to much smaller dimensions for convenience in transportation.

reducel a. visible writing tylpewriting macliine which can be readily a justed to-cau'rse the ty-ye to print at dif ferent locations at their: `r either on or above e liiie at the horizontal plane of the axis of the platen without changing the relative operative positions of 'any of the working parts of the machiwe; and also to improve typewrltingmachmes inthe other respects hereinatcigdescribed 'and set forth in the claims.

In the accompanying drawings:

Figure l is e partially complete side eletation of n typewriting machine embodying the invention, showing the same in position for use and indicatingby,broken linesl a different adjustment of the" machine for rausing thc type to print on a line at thc front of the platen above the horizontal plane of the axisof the platen.

y FigmS-isj a' fragmentaljv inside elevation of thc rear support.

Fig. 4 is a side elevation of the machine being broken away and omitted to disclose the underlying pa rts.

Fig. 7 is a similar plan view of the rear portion of the machine, omitting the carriage and associated parts.

Other objects of the in-4 ont of the platen Fig. H is a partiallycomplete transverse sectional elevation of the machine on line 8--8. Fig. 5.

According to this.l invention, the type-'G0 writer comprises, as usual. the finger keys A arranged in banks or rows` preferably four rows, at the lower front orton of the machine. the paper platen jourualcd to rotate on a transversely movable carriage ar- 6l ranged at the 4upper rear portion of the machine at an elevation above the keyboard, and the printing instrumentalities, 'preferably comprising type bars C ivoted in the usual segmental order. and t ieir operating connections located intermediate of tbc finger keys and the platen carriage. This in vention is not restricted to env particular construction of these and the other working parts or devices of the machine, and it is not '16 necessary tn show and describe in detail the construction of the parts. Other pa. as the aperl feed rolls D one of the ri n spoo s E. the ribbon vibrator F. the paper table G, the carriage escapement. wheel H, 8d feed pinion Ii, the rack bar I on'the carriage meshing with 'the pinion for controlling` the letter space movements-of the carriage, and the drivingspringdrum K for the carrie are, however. indicated in outline in t e dra wings to showtheir positions'or relative arrangement in thev machine and illustrate the convertibility of the machine.

All of these parts are mounted in the relative positions indicated in the drawings and ahoreln'iefly stated, on `a single o'r rigid main frame which is of rockerlike form,Y or is so shaped that it is adapted to be supported stationarily in the operative position shown in Figs'. 1 and 5, with the rear. rtion of'the frame and the platen carriage' and other ,parts thereon at an elevation above the keyboard, and. to be rocked orf tilted on the supporting table yor surface to lower the rear. portion of the frame with 100 the parts thereonirom their operativeposition to a materially lower position as indicated in' Figi; 4, whereby the machine 'is adanfxl to be placed in a carrying case of the small inside dimensions indicated by the V10i broken lines oLb-c--d in Fig. 4:. The maf chine is supported inthe operative pos` tion with its rear end elevated by suitab1e,. :zur sup ofts or legs which are ada. tcduto he move or folded for permittitng t 1e low# 11k i-ring of the rear end of the mech ine: The main frame preferably comprises two side plates 1 andr of the sha e shown in Figs. 1 and 4, and connecting etes or cross bers 3 and 4 located res cti-ve y at the front and upper rear parts o the frame. 5 and 6 represent ribbon spool snpportswhich preferably consist of integral partsa of thefrnme projectin inwardlyfromtlie u per portions of theA si e plates. The side p ates are pro- 4vided at their lower forward portions, preierabl intermediate of their ends, with lugs 7' an 8 sliod with rubber or other suitable Y cushions 9 und 10 which form front supports for the machine, and the side plates incline or extend upwardly and rearwardly 16 from these front supports gradually rcced ing from the s'up'porting surface for the machine. 11 indicates the upwardly end reai-,

wardly extending lower edges of the side plates. The upper reet cross bar 4 shown, I supports the carriage guide track, which may he of' any suitable construction, thc

guide shown consisting of complementary 'race hars 12 and 13 with inter osed antifriction halls. 14 indicates a racket ex- 25,tending rearwardly from the centralpart 'of the track har 12 and forming the support lfor the driving spring drum and escapenient mechanism. j

The irzir suppoits' foi-'the machine are preferably formed hy two hinged 'or folding ege 15 .which areadapted to be 1pl i d in upright position as shown in Figs. and 5, .for supporting the machine in operative osition or to be foldedinwardly iis indicalied 36' in Fig. 7, a d by broken lines in Fig. 2, to perinit the nachmcl ro he rocked onl its front *snppots 9'iind l0 to lower the rear portion ""of the machine. The legs are preferably hinged by knuckle. jointsto liftes 16 and 40 17 which :ire rigidly secure( to the side lates l niidQ, each by two screws 118. Three lioles 19am-e, made in each side plate for each of the screws so that the hinge plates may he placed :is shown in Fig. l, or in either of ytwo other-positions for determining the elc- -vation of the operative position of the platen. As'shown. the hinge plates are sc.-

cured in their lowest positions, causing the fear part of the machine to stand in its 'd50 lighcst position. The printing point X will they lic on; :i line in the horizontal plane of 'th-exis of 'the pinten as in the majority of front strike typewriters. It' the operator pregunto have 'the priming' line iiia more 56 mvenently visible position the hinge lates ylnef's'eeiired in their highest posit-ion, when the parte will occupy positions indicated by broken lines iii Fig. l and the printing line ;..willih`e at y above the horizontal plane of lm rtheI airls4 of the platen. T lic highest and lowestuidjustments are indicated hy the full and `broken lines in Fig. 1. By securing the hinge plates in their intermediate positions i, `the printing line can he located` between thc ftlifpositions indicated in Fig. 1. The lower y taining Y ends ofthleg's I5,` ireerably-have oppo sitely projecting roc er-sl'iaped flanges 20 and are shodwith rubber or other suitable shoes 21 sodhat in an adjustment of the legs they rest on curve surfaces. 22 indi- .70 cafes springs surrounding the hinge pins for the legs an( acting, when permitted, to hold' the legs in the supporting )osition shown in Figs. 1, 2 and 5. .Xs the ru bei' slices extend outwardly beyond the vertical plane of the hinge pin, as. seen in Fig. 2, the weight on the. leg" )crates with the sprin ip re- 'egs in the upright supportin'g position. flicn it is desired to transport` the machine the legs 15 are simply ushedo inwardly an thernachine permittedp to assume the iciimbent position shown in Fig. 4, when the weight of the machine will retuin the legs in this osition. The front supports 9 and 10 a so preferably have a5 curved or rockenshaped lower edges adapted to-rock on the table or supporting surface when the machine is ad'nsted or lowered to its recumbent position. i ylien the machine is to be used after having been lowered, the reiir end is simply raised, whereupon the sprins'will cause the legs 15 to swing out war y to their upright supporting position.

In theschine shown in the drawings the tpieh'ers are pivotedon-a segment 25 of 95 t sensual' slotted funn;- This segment is pivotzll'yfconz'iected to `it fo'nt air of arms 26 fixed tofs. roek shaft2, an .a rear' pair of arms 28 fixed to agrl'ock shaft 29. The rock shafts are jonrnaled at their ends in suitable bearings on the ' freine side plates 1 and 2.

30 represents shift levers fixed to the shaft 27 and acting when depressed to raise the segment and type-bals from normal lower case to upper case printing position. The middle part of the front rockj'shaft 27 is bowed downwardly somewhat, als shown in Fig. 8, to clear thc type-ber actuating links liereiinii'tci described. The two pairs of .firms 26, Q8 and a spring (not shown) form 110 the entire .support for the segment, and snit- :ihlc stops (not shown) iire provided for limiting the movements of the se ient. The perforated lugs 31, shown in Fig. 8, are for receiving the l'enr ends of e. wnrdly extending rods (not siown) that snp Jort thcftype-hzir basket. The segment an( its shifting iiicchanisin are so arra. d that tliey-nillnot project-below the pInne`Of the inclined lpner edges; Lof the frauie side plates whenlhc machine is lowered to its 'incumbent plition, sind the same ap lies to all other par of the'niachiiie. The eels of the central;4 u ie-bars extend sli htly below this plaine, la's"`|=liown in Fig. w en thc ma- 125 chine i voperative position with the segment irrt lower case position, and the front of the shift key und of the lower brink," of 'n'riting keys normally ro'ect slightly above iiphine, indicated by tie ine air of for- 1.15 'A 1f-Za, Fig. 4, which entends in a direction from the front bank of finger keys to the top of the platen but when therear end of the machine is lowered the heels of the central type-bars will strike the table or bottoni of the carrying case for the machine, n nd this will raise the .segment to upper case tion, thereby bringing the lower edge o the type-'bar heels on the line d-fl of the lower edges of thc frame and at the seme time lowering the shift key and the lower bank of writing keys below. the line :1f-b. When closing the carrying case if it is made of the inside, dimensions in vertical section, indicated by the linee w--bv-c--fL Fig. it, the cover will depress the lower bank of finger keys enough to clear the line s-f All of the parts of the machine are thus located substantiel] y 'between the plane of the lower edges 11 of the fiiimel and a plane parallel therewith. represented by the line m41? and the machine can be placed in a carrying case t of the small inside dimensione represented by the lines rrf-b-o-fl in Fi 4.

In order that theV key actions` and their connections with the type-'bars may be located entirely above the phi-ne of the lower edges 11 of the side framemia novel construction is shown in the drawings, as follows:

32 represents a series of key bers all of the same length und nll pivotally mounted at opposite ends on` the front arms of two corresponding series of hell crank levers 33 and 34. flfhesc. bell crank levers are centrally pivoted by wires 35 supported in longitudinal slots in bui-s 3f; und 37 which are rigidly secured at their ends to the frame side plates l and 2. "The upper edges of these bars are transversely slotted to receive the bell crank levers. 38 represents a series oi' draw bros connecting theI rear arms oi thc two seines of bell crank levers :ind 3l? is a link coiim-.cting each drauwbar to its respective type-bar. Only a i'cw of the key bers, drew-bars and links arc shown in order to siinplifv tlic drawings. The drew-bars, except :i cw :it the center of the machine, have upturncd rear cnds which ire of griiduutcd lengths in order to locate the front ends ol' the links Fi!) on horizontal lines half- .way between the upper and lower case, positions of the rear ends of they links so that the type-bars :ircy uctuutcd uliltc in both positions of th',l segment.. A few of the drewburs which have tbc highest rear ends nre stil'i-,ned by integral braces 4U. see Fig. 5.

The rcuniiuing draw-[mrs can be of simple L-slinpc. 'l'lie druw-burs. bell crniik levers :ind key bars arc preferably made of sheet metal stampingsj wbilc the links 59 prefer ubly consist of sucli stzimpings bent into inverted Ushnpe in cross section. The key bar shown in full in Fig. 5 is for the. second bank offinger keys. The other key bers nre similar except that Kthe key posts, or up i raised.

non portable typewriter.

standing parte of the bars which carry the finger keys, are of different len he and located at the proper places lengt wise of the here for the different banks of keys as illustrated in Fig. 5. Springs not shown, atx to return the key actions to normal positions. The keyboard is considerablyv longer than the segment and the upper )ank of keys is nearer to the type-bars than usual, causing a greet divergence in the lines of the type-'liars at the ends of the segments to the keys at the ends of the keyboard. The divergence in the links 39 is lessened by. oilfsetting the key posts and bending the upright rear ends of some of the draw-bars at the end portions of the keyboard inwardly, as shown in Figs. i3 :ind 8. The key posts nreoiset outwardly. inwardly or not at all, as may be desirable to pro ierly space the finger keys.- Eer machines aving only twentyeight typebars in which the keyboard is not so long and especially in such machines in which the upper benk of keymjs located at the usual distance in front of the type-hars and having longer type-hars which require e longer segment. it is not necessary to oli'- et any of the key poste or bend inwardly the upright ends of any of the draw-bzirs.

It will be seen from Figs l and 4 that when the rear end of the macliine is lowered by rocking or tilting it on its front supports Sland l0. the front end of the machine s The front supports are preferably located so that the front of the key-lniard will notrise substantially above* the elevation of tbe upperv part of the platen when the rear end of' the machine is lowered. W'ben the real' cud of the machine is lowered the rubber cushions of the front supports .l and lll are adapted to yield enough to permit the inclined lower edges ll of the frame side plates to rest in contact with the supporting surface of the table or the bottom of the carrying ense for the machine. By reducing the diameter of the platen and the ribbon spools the. machine could be inclosed iu a carrying case of' eren less height lapsible lnnture, but all of the operative parts of the. machine can be mounted on a single rigid frame or support. The work# ing parts of the machine can therefore be ndjustedand tuned up with all the nicety and permanence of ii standard rigid frame, The writing parte of the machine cannot bey affected by any loosenese in the joints Vot" the rear sup- `ports or legs.

While the invention-is herein shown andV described in connection with a typewritingmachine havingifhi'fting segment instead of e shifting platen, it is not intended to 30 i platen isiowered and the vkeyboard raised limit the invention to a machine in whichsmovable rear support whenby the frame the segment is shifted 'for different case;` maybe rocked on Lits front support.

'. In a typewi'iting machine., the comblnaprinting. In a machine having e`fixcd se ment4` and shifting platen, it would only e necessary for the lower edges `11 of the `frame side plates to lie at or below the lower.

edges of the heels of the type-bars with no other change in the dimensions ofthe frame. The prov-isions forlocating the printing line at different more oil less conveniently visible e evations on the platen and for lowering t e rear end of the machine for reducing the dimensions of the machine, have been coinbined in the one machine in this application, but either of these features could be employed independently ofthe other and it is not intended to restrict the claims for either 'printing instrumentailities, such as a type wheel or shuttle, could be employed.
