A still further object of the invention is to provide a typewriter wherein the platen carriage and the keyboard in their operative and in their compact 'ositions are always maintained in an uprig lit position.

Withthese and other objects in view, the

Patented Sept.1'7, 191s.

invention will be hereinafter more particli in section. and partly in elevation for the pun me of better illustration.

m 1 h h y fl f partly in elevation; taken on the line VI- VI' the keyboard iis' 'mounted and connected'to the type-bars in a particular .way and the difierent mechanisms are shown of a particular construction-, it will be understood that many of-gthese" rts may bechanged; and that some-50f t e parts may be ispensed stantia with or others substituted therefor without changing thev nature or character of the invention. l

The inclosing case 10 or other frame or support for the different parts of the typewriter may be variously constructed. As shown, the case or frame 10 comprises a main substantially box-like frame part 11, having a base 11, a rear wall 12 a partially open front wall 12 and side walls 13. The base 11" may be continuous or may have two offset parts 13 and '14, as shown in the drawings, said ofi'set parts" being provided with the usual supporting rubber feet 15, if desired. A top or cover member 16, is hi ed at 17 to the upper part of the rear wal 12, and at the end opposite the hinge 1601 said cover member or top 16 is a front plateor member 18. This member 18 is hinged at the forward edge of the top 16,

and is adaptedto inclose theo'pen front or space 19 of the main part, member or section 11. At the front portion of the main frame part is a keyboard member or frame part 20. This frame part 20 is slidably held to move horizontally within the main member 11 from a normal operative and extended position, 'as shown in Fig. 2, to an abnormal compact one, as shown in Fig. ,5. The frame art of 'member 20 may have a subfly box like form of considerable less height and length than the .main

frame part 11, and said frame part 20 has a base 21 on Whichmay be, supporting feet 22, a front wall 23 having an extended portion, as 24, by which the frame part 21 may be moved inwardly and outwardlyand a top portion or plate 25. The base 21 of the frame part 20 is adapted to slide forwardly and rearwardly on the offset base part 14 and .has its side walls 26 provided with slots 27. These slots 27 areeach adapted to be enga ed by the shank 28 of a -pin or bolt 29, an engagin the threaded '5 t nut 30. Ifhe shank of the bolt 29 has a bearing portion and cessible e p keyhole 33, whe y the tumblers-of end of the shank '28 of each olt is a thumb square portion to fit the slot '27 and forms a i'de for the sides of the frame part .20 during its horizontal sliding movement. QEach bolt has an enlarged head 31 so that by tightening the thumb nuts 30 at each side of the machine the extensible and slidable framepart 20 may be.

.held either in itsextended normal position or in its compact abnormal position. The front p1ate18 of" the inclosingv case is adapt ed to rest against the upper surface'bf the top 25 of the frame part 20 when. in a compactcondition, and mounted upon the part 18 is a lock 32,- as for example a lock such as is employed on desks and which isac y a k through an openting me be disengaged. from or made to engage a s ot 34 or other holding means inthe top e locli ame-Ia 12 and are adapted to inclose the cutawayportions 37 of the side Walls of the main frame part 11. The side pieces 36 have beaded or rabbeted edges and the top member 16 may also be provided with a; rabbeted or beaded edge so as to lock the end "pieces or members 36 in a closed position when in the position shown in Fig. 5.

On the frame part 20 is mounted the keyboard 38. The keyboard may be of the usual standard or universal kind wherein a :plurality of banks or groups of keys are arranged each operating individual type, such banks being in three or more set-s,'according to the number of printing characters,= and whether or not a single case or doublecase shift is employed. The keys 39 are eacharranged upon a vertically movable stem or rod 40. Each stem 40 is 'guided in a bushing or tubular part 41 extendingupwardlyE-from the top 25 of the keyboard frame part 20, and at the lower .end of-each stem 40 jis a yokeor head 42 towhich is'pivotally-.-eonnected the arm 43 of a bell-crank lever? 441 The bell-crank lever 44' is pivoted at 45 to a lug or bracket 46'extending inwardly-from the rame part 20, said part 46 extending inwardly from the top 25 for two 'banlis or rows of key-operated levers and from" the front plate 23 of the frame part 20 forthe third row of key-operatedlevers. The keyoperated. levers 44 have a pin-and slot-eonnection with the'stem's 40 and .under each head 42 is a rubber or other stripdifft to take the shock due to the return movement ofthe rods. 40. The arms 48 of the key operated bell-crank levers are connected to springs 49,-

there being a spring for each 'lever' fiahdieach spring being connected at one enemam of the frame part 20 and at its otherend to one of'said levers. A linkorconnectibn. 50 extends from eachke operated -lever and has one end held to t short arr'nfil 'of a lever 52 The links or connections 50- nay be of wire, as piano wire, for" of any other desired form, and is adapted when a key'is.

depressed to force the u per; arm" 53 of; one

of the levers-52 inwa ly. The l evers 52 are all mounted ona common pivotrod 5'4 which is curved according to the arrange-1 merit of the levers 53 and the .parts-actuated j thereby. The arm 53 of each level" 52 fis.

pivoted at 57 to a lug 58 of aftype of characters or type 60 thereon, in this case three charactersbecause. there is double case shift, .one of said characters representing the lower" case type, another character the upper case type, and the third character or type, figures, punctuation marks, etc.,' this arrangement being. varied according to the construction of the machine. The ty eheads or blocks 59 are 'heldvto bat-s61. ach'bar 61 is guided to slide in a bearing62, and is normally forced in one direction by a spring (33,: one end of which held tothe forward end of said bar and "the other end toa part, oftliemain casing or frame. The bars 61- 'are="lield in slots and over the bars 1s a finishingand a retaining, plate 64. The bars Glare arranged infla curvetlpath so that as they are propelled or forced inwardly they will move toward the printing pointuto im-, pressa character. upon. the workheld upon the platen 65. The bars 61 are thus substantially radially arranged with respect to the printing-point so that all the type ofall the bars as each one is forced inwardly through themov ement of the levers-52, links 56 and bars 61 onthe depression.- of thekeys 39 "will strikeat the'samepoint on the work sheen This arrangementof the .t pe-bars is not broadly new, Instead of the typebars ha ring. a horizontal sliding movement they may have anpupward and rearward mo-veinentas is common ll'lmo st standard visible-writing machines.

The banks or-groupsof keys 39 and the bell-crank levers ll all move bodily with the frame 'part 20' toward or away" from the type bars and the platen carriage 65 .and during such movement said banks of keys and levers maintain a fixed relation with respect to. eaclr other,".thns;adapting the keyboard as a unitto be moved into the main frame member to make the machine compact or to be moved to an extended operative positionatlhe will of the operation;

The platen carriagebli has a platen 66 mounted. upon endpieces of the carriagein the usual or jnany preferred way. The car riage has a" base-67 {which has tongues orflis otherwise constructed to move-transversely of the. machine on-the carriage bed 68. :The

carriage bed. is held-tomove ,verticall at its a ends, as \v-illcbepresently describe 4 The platen carriage mayhave the usual parts mounted thereon which coiiperate with" the platen. such-.as line-spacing -1nechanisrn,rib-

bou avibrating mechanisnuand other features usually employ-ed? in connection kwith typewritingmaehmes; but such parts are not shown or described 1n. detail, as they form no part of the present invention, said parts l!t*l'llf,1 0f any suitable or preferred construe- The links 5(l'are'tguided in a transversely utoullingjbar 69, there beinglan aperture-1n alid but for eachlink sot-hat the links are" irelation: wsa'id'ibar and without .liab

pro rly held spaced apart. The bar' 69 is hel to one.end-of"links'70 and these links at their other ends are pivotall'yheldat 71 to the sidessof the framepart 20; The ends of the bar 69, are guided ma s; 72 of arms 73; Thesearms 73 are loeated'on o posite sides of the machine and are pivotal y held at 74 to lugs 75 extending upwardly from the part-14 of the main frame part 11. The

upperends of the arms73 are pivoted to links or conneotin ,rodsflfi' andflthese links 76 are pivoted att eir inner ends to arms 7 7.

The arms 77. are held tostuds and on said studs are eccentrics 78 so that as the links 76 are forced inward'thearms or cranks 77 will rotate the; eccentrics 78. In th'e comp'a'ct position of the partsas shown in Fig.

5, the printing; point of the platen is below the plane of travel of the lower base type on the type heads or blocks; When thekey; board frame part 20 is moved outwardly to a normal operative position,- the transverse bar 69 by reason of its connect-ion with the links 7 0 will force the'arms 7 3 downwardly from the position shown in Fig. 5 to that shown in Fig. 2. This downward movement of thearms 73 wilh'force the links 76 forwardly and. such. forward movement oi said links will rotatethe eccentrics and this will elevate-the carriage and platent oits normal operative position 'wherein the-- rinting point of the platen is in' a direct lme with thetravel .or movement of the lower type character ofthe-type-bars. In this ositi'o'n the platen may be shifted for the ifferent type charactersinanysuitable wayand maybe restored'itoitfs normalposition either by gra -1 ity or by spring orv springs, not shown, for

riage and platen allowing the same to drop below the pathof the type to an inoperative ositioni During this compact movementf he wire link connectionsare raised by ,the'

bar 69 and-Ia-rejmaintained. in' their roper becoming} entangled; A connection is thus" always-maintained between the key-operated levers and the type-bars, and during the ex tended and compact movement of the keyboard the normal and abnormal position ofthe platen and carriage isi-automatica-lly effected through the action 'ofjthe eccentrics i 78 and the connection: between said eccentrics' andithe keyboard frame part 20 as; already 'describedit The drawin s-1 Show 5 a] particular as" escapemenfi'f'meehanism: "for controlling letter -feed-movemenm6t thtr platenmarriage;

the i also'ribbon mechanism, and means whereby I 1 the platen carriage may be shifted in a vertical direction to adapt the type-bars to have'a plurality of type thereon. These features forin no partof the present invent lon but are claimed in other pending appllcations filed by me.

From the foregoing it will be apparent that a simple and eflicient machine is provided. wherein a keyboard frame part is slidably held to move within the main frame part, that the-frame, parts may be made to provide an inclosing casing-or said frame parts may be constructed on the lines of the usual typewriter frame adapted to be placed in a separate carrying case or to be used ndependently of saidcase, that meanst it're provided whereby the platen carriage I'hay be, given an abnormal movement to make the machine more compact; that an effective key-action is provided whereby a positive' 1 connection may be always maintained between the type-bars and the key-operated levers both in the normal operative position and in the compact position of theparts, that thekey-action is such and the type-bars are held and travel in such a way that. less noise takes place during the printing opera-' tion than is the case with the usual rearwardly and upwardly moving type-bars; that means are provided whereby the nor- .mal' position of the platen carriage and the abnormal matically uring the extension and compact movement of the keyboard frame part that "means are provided whereby a Wire or other flexibleconnect-ion may be used between the i keys and the type-bars and such flexible connection controlled and-prevented from becoming entangled with each other; and that said machine .is simple in construction,-ef fective in use and may be readily made and assembled.
