.Be it known that MATTHIAS K; Meant citizen of the United States, residing at Hol-.

lidays Cove, in the county of Hancock and State of West Virginia, haveinventedcertain new and useful Improvements in Type-Writing Machines; and I do declare the following in the art to which it appertains to make and use'the same, reference being had to the accompanying drawings, and-to the letters of reference marked thereon,

The present invention is an improvement on typewriters of thatolass whichis' portable, and designed'to be soldat a moderate cost and within the reach of everyone.

the invention is applicable, is thatin which the-type-b'ar is separate and independent,;

anddesigned to be held in the-hands of'theoperator, when using the machine, the proper letter or character to be printed being brought in position'on a counterbalanced tilting'arm, bymea'ns of an indicator or pewter provided 1 on thelatten.

The invention is designed most especially.

as an improvement on the machine for which} on May 3, 1892, Letters Patent of tlie United States, were granted me, No. 4=73,94=5.

The improvements consist in the provision of ribbon and ribbon feeding-mechanism which are operated by the type-bar; in meoh-f anism for feeding the paper over the paper support in a positive-manner in either direc-' tion','and inthegeneral construction of the machine, as will hereinafter'more fully-ap' pear, reference being had to the reference letters on the figures of the annexed drawings,

and to similar letters of reference in the following description.

In the drawings:Figure1 is a perspective View of a type-writing machine embodying the invention. Fig.2 is a top'plan view of the carriage, showing the ribbon mechanism on a larger scale, the counterbalanced tilting arm being removed. Fig. 3 isa deta1l v1ew showing the manner of turning the paper-- feeding rollers in either direction as desired.

which form a part The particular style of machine to which.

feeding the ribbon or winding the same from onespool-to the other, the operation being shown by dottedlinesw Thebase Ais rectangular and'preferably of wood, and is provided at its endswith metal pieces Bfr'om which rise vertical standards'which receive andsupport longitudinal bars 0 and o thatare' arranged in parallel relations. These bars a and 0' support and form guides for the carriage D, Thebar c is notched on its top side to-provide aseries of teeth which are engaged by 'a pawl E and move'the carriage over the paper a distance" to properly space'theletters and characters being'printed.

The papersup'portli is disposed. midway between thebars c and of parallel therewith,

and is preferably of WQQd having a strip of rubber or other flexible material f on its top side to receive the impact of the typewhen writing. Longitudinal rollers G and G are arranged parallel with and one on each side of the paper support, to engage with the paper H. and feed the same over the paper support.

Pinions g and g on one end of the journals of the rollers G and G' ,respectively, are (adapted to mesh with a corresponding pinion e on the-end of a thumb knob 'I by means of.

which the'said rollers are positively operatedto move the paperover the paper support in ,tance. The rollers G'andnG' are adapted to the required direction, and the proper dismove longitudinally in their bearings tov bring one or the other of the pinions g andg in mesh withthe said pinion 7; so that. when rotating the th11mb knob I the papercan be 7 moved positively-in the -desi red direction.

Thebarria'ge D is composed of a bar extending from one to the other of the .bars c and'o and hav'ingsleeves at its ends to receive and slide upon thesaid bars. A rockshaft J is journaled at,it's endsin lugs 11' projecting vertically from theends'of the car 'riage D. Onef end of this rockshaft is pro-'- jected beyond a lug d and has a crank arm j moun-ted thereon, to which the pawl E is pivotally attached. The lower bent end of'this pawl engages with the teeth on the guide bar C-and produces a movement of the carriage after each operation of the counterbalanced arm K. The stop projecting from the rock- Shaft J limits the movement of the latter when regaining itself-after. beingoperated by engaging with the carriage or a portion thereof. The counterbalanced tilting arm K' is attached midway of its ends "to the rock shaft J and is weighted at one end, as shown attic, and is providedat the opposite end with a guidelc' and apointer 10 The guide it is composed of a vertical piece 10 against which the type-bar rests, to give it the proper position, and short bars 10 whichare designed to 7 come between the typefand extend onweach efiectedin colors by moving the spools so as side of the type to befprinted, thereby preventing longit'udinal'movement of the typebar when depressing the latter.

, Jlhe ribbon supporting mechanism is composed-10f side-bars L 'andIJ which are sup-- ported between their en'ds'on the carriage D, and a cross bar L which rests upon the bars sand at-itsends, Angular'shafts-lll, .M" are jou-rnaled at their ends in the ends of the 7 side bars L, L, and have the ribbon spools These spools N, N

N, N mounted thereon. are free tomove on the shafts to use the ribbon 11. up betweenits edges. By providing ribbons of different colors the writing maybe to bring the desired color ribbon in operative position. The shaft M is provide?" at one end with a wheel m on which acts a spring mito-serve as abrake to prevent the ribbon payingoif too rapidly, and afthe' othe'r end witha knob m by means of which the shaft is rotated to wind the ribbon from thesp'ool N onto' the spool N. vided at one end with amatchet wheel m. A

, weighted lever O isloosely mountedbetween its endson the'same .endof the shaft Mwith the ratchet wheel m and has a pawl 0 to engage-with the teeth of the said ratchet wheel and move the ribbon after each impression.

' The inner end o'of the lever O is hook shaped 4 and is in-the same line with the guide'k' on the-arm K, so that the type-bar will actuate type being indicated-by a corresponding the arm- 'K'and the lever 10 at the same time. As the-inner end of the lever O is depressed the pawlo-will engage with the ratchet-wheel mand turn the shaft-and spool N sufficiently far-to move the ribbon the distance of a-letter orcharacter, so as'to bring-a new portion 1 of the ribbon in position for the printing of the nextletter or character. A detent, o -en+ gages with the ratchet Wheel mandprevents v the latter from turning'back, The type-bar P is'straight and has the type 10 projected from each edge,-t'he letter or characteron each character-on the side of the type-bar directly opposite the type 10. The paperH to be written upon is passed'over'; the paper support vand under the rollers G, G, the type-bar is grasped firmly in the hand and held at right angles to the paper support, and the desired letter-or character to be-printed is brought opposite the-pointer Now, by depressing the type-bar the character is printed. The

type-bar engaging with the weighted lever O The shaft M is pro-- at'the sametime eifects a movementofthe' ribbon. On elevating thetype-bar to bring another letter in position-for printing, the

weight is will return the arm K to a normal position, and through the pawl E move the carriage'over the paper in the manner hereinbefore set forth. After'one line'has been printed, the paper is moved to anew position by' the rollers G and G, and the thumb knob 'I in the manner previously explained.

What I'claim'to'befnewin my invention, and desire to secure by Letters Patent, is'- 1.'In .a type-writer the combination with the base having a stationary paper support,
