' VVh'ile I' have shown lth invention as applied 'more lmrticularlyl to a'typewriter i-n-v which 'the platen and 'carriage are oldable forward into overhanging relation to theV y keyboard orotherwise constructed so 'astoj` make the machine more compact when not in use, it will be ,understood 'thatthe invent1on is applicable inwhole or in part of various constructions.. l The frame 10 may be of .any

to machines suitable'fconstruction andmay comprise the'sides 11 and a rear plate -12 integral with the side plates. At the rear corners of themachine frame are brackets .13 in w'hi h are'y movably 'held' the 'guideposts -or sli es 14.., These posts or slides may be connected at their-lower` ends by a transversely extending rod 15 and this rod may-be connected to shift levers 16 Vand 17 by which the. slides maybe given .vertical 'shift movementin the usual or in any prefcrreellway.4 rlhe posts or slides' 14 at their upper endsare secured 'to arms or bars 1 8. These barsjor arms 18 each-have' .an arm 1.9.pi\otedthe1eto, as at 20. 'A car-v y riage bed 21 is rigidlyheld to the arms 19' at their rearfportonsand'said bed with-the arms 19`form` one member of ai foldable support, the other member comprising the barsl 18. A transversely movable carriage is suitably held and guided on the bed 2L and in-said carriage is mounted 'a' platen The carriage and platen are adapted to be movable forward with the fojldable member of the support. into overhanging relation to the keyboard as is usual in this type of ma chine.

' A number ot key-levers 24 are pivotally held to. a plurality of transversely extending` rods forming a keyboard with three set-s or banks of keys, not shown, and each keylever is held in'` its normal position by a spring '126, one end of'which is attached to one of the key-levers and its other end to a transversely extending bar 27. Each keylever vhas a part QS which if; connected by a link 29 to a type-bar 30. The typebar 30 may have the usual number of type andis adapted on the depression of a key-lever to be forced upward and rearward torv printing purposes. the said typelbar being pivoted to a-hanger 31 or to a segment or other support. The keydevers Zleaeh have a tongue orv projection which is adapted to engage a universal bar Il. This universal bar may be provided vwith vertically extending integral arms--l. the upper `ends ot' which are pivoted. at 5.3, to the arms 15h of bell-crank levers 3T. There are two bell-crank levers 3T located on opposite sides ot'rthe machine and 'said bell-cranklevers are pivot'ed. at 38,

and each have a part 39 adapted to enter a vertical slot l() in one ot' the vertieally eX- tendingI arms ll-located at opposite sides of the machine. These arms 4.1 are mounted upon the transversely extending rod l5 so as to rock thereon and to partakev ot' the shift movex'nent thereof. and at the upper 'ends said arms are connected by an integral transverse bar -le forming' withthe arms a rorkinp universal bar trame or eseapement trame. The bar i2 may beprovided with a tappet t3 which isadapted to engage the bendable end Jt-l of a dog carrier. The-dog rarrier may have mounted thereon the limher or loose donY 4G and the tixe'd dog t?.

This 4lever has an through which may be seen d of' thei Vit will nur ' 'l The carriage bed 21 has a guide and type aliner 70 secured to the under face thereof.

` This alinerand guide or device maybe made lomV steel' 01'. other material and'isjsubstantial'lyy Lsha'ped.'` It has inwardly extending lugs or parts 71 'through which passy4 the screws 72 .for securing the same to the carriage bed and` has a vertically extending plate-likeportion73. The portion 73 of the. aliner or device 70 has an elongated slot 7 4.- at the lower portion thereof-and' aninverted .y

substantially T-sha'ped slot 75 at the upper portionfabove which slot the ends or parts i 76 are bent inward, as at "77, to, guide aline the type at the printing point..

The device ,v forms a support fora ribbon holder 78.4 'Th'isribbon holder may 'be of sheetsteel and is of a skeleton lform.- The ribbon holder which" forms a -part oi the ribbon vibratorlias substantially` C-shaped parts 79 located onopposite sides of the printing point and have vertical slots 8'0 which are intersectedv bysmaller angularly arranged slots 81. The'ribbon is'threaded Vthrough the slots '81 and 'into the vertical slots 80 of the part 79 and extends across the open space between the C-shaped parts 79. The parts79 of the" ribbon holder are -SGP separated by `a suitable space below said provided. 4Theribbon holder is provided i with two integrallips or parts 83 which` extend inward about'- the edges 84 of' the aliner and guide 70. At the lowerend of the ribbon holder. is a pendent part' 85,4 the lower:

' end of which is bent upward a'nd is substan- `ti'ally T-shaped, as at 86,` The part S6is passedyinward through the slot 74 so as to' extend transversely of said slot and together with the li s 83 serve to retain and guide the ribbon older on the type aliner. part 85 is of substantially the same width .as the slot 84 and the edges 87 of said slot form guides 'for the lower end' of the'ribbon holder. The holderis thus positively guided `in `itsm` vertical and lip-and-.down movement.

A pin or projection is located at the reary of 4the ribbon holder, the forni. of pin shown being the body of a. screw, and said projection entersa slot 89 in the outer end of tlie vibrator arm 56. TheV holder thus forms- .one part or member of the ribbon vibrator and theaim 56 another part or member, tlie slot'89 permitting 'the rocking movement of the `arm 56 and the vertical movement of the ribbon holder 78. The lugs 83 are Vshown in their extreme upper movement as en'- gagiiig the lower' edge of the intiirned type guides 77, but no stop, as for example the shoulders of the guides 77 ,.is necessary be- 'cause the` ribbon vibrator is moved positively up and down by the lever 61. It will thus be evident that when thel v1- bi-'ntor inc ,chanisnrv isv actuated by, the depres-` trrsiorn of any one Aof the key-levers, the arm on the carriage bed with the rib arts 79, a relatively large opening 82 is The" 56 will be rocked and through thisrocking action, the vibrator holder will be moved vertically to carry the' ribbon to and from the printing point. It .will be evident 'also that by reason of the mounting of the alineror device 73-on the carriagebed seas to partake of -the shift movement of the platen and carriage, `there is no relative .change between the position of the aliner and the 'printing point, and 'further by mountinohejaliner vibrator and ribbon mechanism, they' can all partake of the folding movement ofthe platenaild carriage. .I y y A line gageg90may bese'cured to thealiner and guide ore-device 70 at the rear thereof l and at the rear of the ribbon-vibrator. i This- -line gage is provided with ak relativelyr large opening'91 substantially. Vlshapeff at the upper end to provide a cornespondingly shaped part 92, the apex of which is directly over the printing point, and has outwardly extending Varms 93 on each of which' may be a scale 94. The upper edge-ofthe scale is adapted to registerwith the printing line@ and said gage at its lowerportion is secured by screws 95 oi' otherwise to the inner part of the aliner. The upper' .portion 92 of the gage might 4be made to extend inward and slightly vabout the platen so ash to press the worksheet against said platen, the said line .gage being also ada ted to hold small articles, as labels, cards ,and the like which ca nnot well be -held by the usual paper fingers.v

. Extending lengthwise of the -platen. and carriage is a'scale 96. This scale 96 is mounted .to travel with-the carriage and has a scale 'both at the upper and lower edge there.-

' of. TThe scale is supported by downwardly extending arms or parts 97 of the paper apron 98, Fig. 3, and has its upper edge 1ocated adjacent `to the surface ofthe platen. IThe scale 96 is adapted to be moved with the lpaper apron away from` the vpla'te'n 'when .placing the worksheet thereabout, said means not being shown as it may be of any preferred form. It will be noticed that the scale extends across the aliner and ribbon vil brator and the op'en space formed in 'tliealiner and in Vthe ribbon vibrator holder "T8 is such that a partof the scale may beseentlirougli such opening for' registering purposes at the l irintinvA oint and to assist in such registra'-4 fr. v Y. s tion, an indicator, as a niark99, may be employed, or instead of a mark an integral pro jcction forming a pointer or index, as at 100, may be used as shown in Fig. i', the lconstruetionshown in said figure being identically the saine .as 1n the other views except `as to the integral pointer'or index 100. It. will Abe 'seem'therefore that the scale, pointer. aliner.. "and guide, ribbon vibrator. and actnjatm".n therefor, all partake of. the shifting more.A

ment of the platen carriage and also in it! folding'moveinent so as to nioveall the puts stamped from sheet metal, as steel-or other materialthat effective means is provided whereby thetype aliner may properly guide the ribbon holder: andthe said meansis simple in construction and may be readily asV sembled. l
