is not material. Said openin of the guides F accommodate the `vertical s iding st ems G, for the bed H of the platen carriage I. This bed ll is adjustable or folda'ble with the )laten carriage into a compact relation to t e keyboard or to the type bars of the new ty eivriter, but asshown herein, said bed an the platen carrlage'are adapted. to be adjusted into overlying or overhanging relation to the keyboard, see dotted lilies in Fig. 2, thereby disposing the phiten carriage in exceedingly compact relatioli to the other parts-of the machine for convenience intransportation. To secure this folduifg adjustment of the carriage bed to the p aten carringe, I have representedthe vertical movable stems G as bein'r provided with horizontal arms r/ the liitterxeing fixed rigidly tothe' stems and extending outwardly from the same over the type bars C. The carriage H isv fastened rigidly to other horizontal arms g', which are disposed parallel tothe urina y and are connected pivotally therewith in a suitable way as, for example, by pins or bolts sce Fig. 4. lt is evident that the carriage d H is movable or shiftnble with the arms g when the latter are turned on the ivots in order to assume the dotted position of ig. 2, or the full linepositions shown by Fi 1 2 and 0 of the drawin The lower eniiof the stems G extend be ow the iides F, as indicated by dotted linea iu liig. 3, said lower ends of the stema being connected by a horizontal bar or rod G', which is attached rigidly to said lower ende of the stems and lies within the back of the frame A.

The carria bed H may be of any suitable or preferre construction, but as herein shown, it consists of a simple flat plate fiisteni-d ri idl to the arma g. Said bed is provide at its middle with a slot li, and en the rear edge of the bed is a guideway h having any suitable forni in cross section. The aten carriage I may also be of any suita le or preferred construction, with a view to supporting a rot/ary platen or type cylinder J aa well as the various other parta required for operating the platen in the manner well known to the art. Aa shown,

the l'aten carriage consista of the end lates i', w ich are joined at. their front an rear edges by rails i", the front rail being agited to reet directly'ii n the carriage H while the back rai is tltted in the ideTi',

and plates of the carriage frame support a paper clamp J', which extends longitudina ly ofthe platea carriage and has a section thereof curved to conform to the platen J, thereby disposing it into cooperative rela tion ti'the platen tflilir the n ingtepa rin ecarria is r clamp, hover, may be rfitdiod wpitgien wide limite.

actuated movement. by the operation o an esca liereto attached, reiuires an eecapem purpose of contlny The carriage direction byv anappro riate tension mechaniam, which, however, oes not. form a part of this invention. As illustrative of a suitable type of this tension mechanism, I have shown t c carria bed H as provided with'a spring rum or spool K, see Fi 4. This drum is mounted on the. under side of the carriage hed for rotation thereon imder the energy of its spring, and to the drum is con' net-.tet a coi-il 'or strap le, which is anchored at its free end to a corner of the platen carriage l,as at le', wherebythe drum is adaptedto draw the platen carriage in the nequired direction. This platen carriage is limited to endwise movement directly in a rectilinear path by the described form of guide devices which are employed betweenV the platen carriage and the carriage bed, und said carriage is given a ste by step feed pementmechanism, which is adapted to be actuated by the type bnr keys or by the s acing keys of the typewriter, als will present y appear.

This eacapeineut mechanism must coperate with the platen carriage when the latter is rained or mljimtedveiticall to a plurality of ditl'erent positions, in ori er that. the ae\'- eral writing characters, such as the lower case letters, the up i r case letters, the punctuationinarlc-i an the numerals. Said eseapement mechanism must, also permit of the adjimtmentv of the carriage bed to the platen carriage to the required folded or unfolded jnmitions without takin the machine a )art or dismantling the wor ing parts tliereo und the parts of the eacapement mechanism must be brought into coperative relation to each other when the carriage bed and the platen carriage are returned to their normal working positions.

yln the drawings aeeoinpanyin this application l have shown one type o esca ment mechanism which fultils these con itione. and I will now proceed to deacribe the name in detail. An element of this eecapenient mechanism is a horizontal bar L ra in lengthwise of the carriage and attac iet thi-reto, pai-takin of the e|idwisomoveinent thereof, said bnr icing provided in its bot! tom ed with a. .series of teeth forming a rack. ilnother element of said escapenient mechanism is a dog carrier ne resented more clearly by Figs. 4 and 7. id carrier is shown aa a flat plate or arm M, arranged referably on .the under side of the carriage H, to which it is connected pivotally in a suitable way, aa for example. by the llt'.

vertical pin or acrew m. The dog earrier ie prevented from foldin or droplumr'ont1 of lace by e lt r m', l xed to thu tfnrrln o H, and the ree end ot eid d ie arranged to extend across the. s o t It ut the carriage bed. This dog carrier is provided with two doge O O'. the dog (l boing fixed to or intt-gral with the otht-rtt'ise frotvod of the verrier M, and exit-toting opwerdly therefrom, through the slot li. no tot to have en agement normally with u tooth o! the rack rl 'lht.dout'onntituttswhut mty bn termed tho listed dog, nlthough it ia el able of movement withthe dog mtrrier. he other dog O' is tlisjmsvd alongside of the fixed dog 0. to n'lut'h it is t-ounoetetl pivotitlly ns at o. und tuminst tht` tot ot thin pivotal dog 0' nt'tn u primi o'. tht latter being attat'hed to thtdog t-tu't'it'r M..

I employ different key levers for shiftin the p aten carriage vertically and to di erent points as shown by Figs. 2 and 6 lor permitting the upper ease characters and punctuation marke and numerals to be printed on the platen. One of said shifting evers is indicated at V, arranged at one side of the trame and provided with a finger piece v. This lever is fulcrumed at a point intermediate of its length on a rod u, eee Fig. 6, and the rear end ot the lever is connected with the md G', the latter luniting the aliding atema on the platen carriage. The other shifting levenlW operates to lift the platen carriage to itahighest position. said ever being located on the other side of the frame and it is rovided with a linger piece w, said lever v being hung at s point intermediate o! ita length on one of the rods E: Tliia lever is provided at ite rear end with a plato or hanger ne, having a aletas', and throu li this slot passes a rod X, one end of w ich ia'faatened to the lever V, and the other end ia attached tota short lever Z. Said ahort lever lies alongsidev of the lever W,l to which it is connected by the rod X, andthe hanger ai, andgthia short lever ia pivoted as at a on the machine frame, ita other end'being loeaaly connected with the rod G o! the vertically sliding stema for the platen carriage. It. will be eeen that the lever V ia'adapted to act directly on the rod G' {.or raiaing the stems (i and thel laten carriage to the poaition indicated by ig. 6, the rod X being arranged to play in the alot of the hanger ai, so aa not to disturb the other lever W. Thil last mentioned lever W when depressed raiaea the hanger :a and the rod X, t e latter workin the levers V and Z, agaattortahiaethemda d ed b l. ria o e 'tion in icat `ig. 2.
