In this embodiment I einplo i. A frame attached to the body of the typewriter and consisting of two upright main brackets N connecting .which are two square or other suitable rods P and Q, placed parallel to each other sind :it right a les to the brackets. The rods pass throng .and extend beyond. the brackets so that milled disks X X or knobs or gearing forroteti the same may be att-ached thereto at 'ne en as shownor at both ends. The rods P and Q are independently revoluble, and b the use of devices presently to lbe'explaine ro` tation of; rod' or shaft P wiluladvenceor retract a. main work-sheet a, hile;a n underlying wrk-sheet blinay 'ne similarly but in- -ffdependently' controlled by the rod Q. These ii'ork-sheetswprogress along said rods step s by s tepjas the types are operated, and .one

'rollei's"D and E, the4 roiler D being above tlie p'riiitiig'point of-thc typewriter, and the rollerE being belowethe printing point, and the outer'or main work-sheet e running around the lower roller or guide E and up.- A. vwardl v'to the upper roller or guide D, A-whe'r'e y'.-,the'-movements of said work-sheet yni'ayibe controlled. The rod P is parallel 4ivit h"tl'ie iaraicls. 'o f the typewriter carriage, "2'5' and, byturningthe linger-piece X on the end-'of'saidrod, l'l4`i,j. 2,'the upper roll D maybe revolved the in'ain work-sheet a,

. adjusted-accordingly, 'whereby line-space 'end othei'z movements of sheet a. may be ro' veo duced; :The rollerD slides along the ro or shaft?, `and theroller E may be carried in 1 the' Iowei ends of thebrackets L, 2 andiff. The rod or shaft P is square, but is mounted-"at ts ends for`revolution. The rller-Dinay be hollow and in either end is l ai'nietalibush with a square center through I which thef ro`d P passes. The bushes projectfa` shortv distance and to them are fitted theltwobrackets L which support the roller 4 0 E, .,Whi ch maybe solid and of which the piv- Q ot'al', extremities project into and beyond *i fbearings 'in' the'brackets L. Knobs or equiv-v alent-'means for rotating the roller E when reqi'iiredj may be provided. The No. 1 car- :rier- .i's soarranged that the most forward partait vthe roller D is vertically above and the r'nost forward art of the roller E is un- -der"i'iid slightly in advance of the typing pointofthe typewriter. The whole ofthe partsfof.thiscarrier are so arranged that the roller Dl'an'd the rod P shall be capable ot' ,mutual v rotary motion; the roller E shall be capable-of separate rotary motion; and the whole-carrier ca able of horizontal motion ,5 along" the rod within the limits of the frame.4 Thebrackets'L are fixed on a carriageitnot shown) connected to the escapeiiientinechanism of the typewriter. 13. 'A carrierNo. 2) .supported by the rod v 60 ,Qi and consisting of tv i-'olrollers AA and B placedv parallel toeach other and to the rod Pand connected to each other by an endless band Y extending practical-ly the full length of the rollers. T his carrier No. 2, whichI is ccnwcted to travel with the typewriter car- ,ject a short distance and upon them are susringe, used partly for the purpose of linet'ecding and otherwise controlling a worksheet Z) which underlies the main work-sheet o, and is intended to receive ty e impressions which are duplicates of tiose made upon the sheet o. These duplicates may be iliade either by -iiiterposition of an ordinary carbon sheet or by the use of a special inkribbon mechanism, which will presently be described. The forward roller B is a revoluble platen, and occupies a position-between the upper and lower rollers DVE, which control the main work-sheet a. will presantlybe seen, the platen B, which controls the underlying work-sheet 1),.4 can be dropped out` of 'printing position, so that no duplicates will be made thereon of the type impressions which are produced upon the outer sheet and a device which supv ports or backs the sheet a, so that it may receive the type impressions at such times, will now be described, with its associated de vices. The carrier No. 2 also comprises a meta? platen bar C, referably faced with rubber or other suita 1e material, parallel 90' to the rod P, and two end brackets M. The

roller A may be hollow and in either end is a metal bush with a square center through which the rd Q, passes. The bushes propended the two end brackets M which support the roller B and the platen bar C. The' roller B may be solid and its pivotal extremities project into bearings in the brackets The whole of the parts of this carrier are so arranged that the roller A and the rod Q shall be capable of mutual rotary motion which by means of the endless band will be communicated to the roller B'; and

the roller B and the platen bar C shall be 105 capable of oscillation in a path which is part of the circumference of a circle de scribed about the center of theerod Q so that alternately a point on the roller B and a point on the platen bar C shallbe presented at a point, which-is iminedia-telybehind the typing point of the type Writer; and further the whole carriershall be capable of horizontal sliding motion along the rod Q within the vlimits of the frame.

The brackets M are joined by the platen bar C and forni a frame hinged to swing up and down in the manner just described. This frame is connectibleto the-typewriter carriage by means to be presently described, 12b so as to travel with said carriage; said frame, together with the revoluble platen B, fixed platen (Tand feed roll A, being also capable of independent adjustment in a direction longitudinal of the plateiis.

et. AnA elevating and depressing attachment supported by the main brackets N and consisting of two round rods R and S placed parallel to each other andto the rods P and "Q". and levers T, T', 'If-zcounecting them 130 together, the levers T being fulcrumed lat T* in the end brackets N. The ends of the rods R land S project through slots in the brackets N the rod R passing above the roller D and through two guide rollers H described later. T he rod S passes between the roller A and the roller B and through a circular hole ircach ofthe brackets M. The whole of the attachment is so arranged ,that he rod R can be alternately elevated and 'depressed in a vertical direction and to a distance regulated by the length of the slots in the brackets N; that such movements of the rod R shall be communicated by the Vmeans of the levers T, T, T2, to the rod S so asto cause the rod S to oscillate in a path which is art of the circumference of a eircle described about the center of the rod Q.; the rod S in turn communicates motion to or shifts the roller B and the platen bar Cwby means of the brackets M and so produces the oscillation ofthe roller B andthe platenbar C previously referred to, and into Ill their centers and are placed immediately 1h front of the two spools G. ers H are `fitted with flan es set apart at a The guide rolldistance equal 'to the 'wi th' of the carbon ribbon or ink ribbon. From the guide rollers ll are suspended the two-tracks J which are nngles to jboth.

maintained inl a vertical position immediately under the guide rollers H -by means of projections from the brackets L. The ribbon tracks J are cut' away at their lower ends at an angle of 45 degrees to enable the ribbon to Vbe doubled around .and passed from one ribbontrack to the other at right connected at their lower ends by the ribbon guide bar K which' ,passes in front of and parallel to the rollerB. This guide bar K ias a groove cut in its upper edge along which the carbon ribbonis drawn and whic I sheets whenthe attachment is elevated'. The

serves to keep the ribbon straight as otherwise it might buckle/or curl and so fail to be inserted between the original andl copy carbon ribbon is plaeed'in position by` be- .ing wound around the left hand spool from which it passes over the left hand guide roller, downl the left hand ribbon track J, along the groove of the ribbon guide bar K, up the right hand ribbon track J. and over the right hand guide roller on to the right band spoolor vice versa. The whole of the attachmentl is so arrangedytl'iat, except -the The ribbon tracks J are .two spools G, it can be alternately elevated will hold the ribbon immediately 'behind af horizontal line drawn parallel to the roller B through the typing point of the' type writer, and between the typing point and themost forward'point of the roller B; and that the whole attachment willbe capable 'of horizontal mtionalong the rod R in company with the carrier No. 1.

6. A deviceto enable the carrier No. l and the' carrier N o. 2 to be alternately connected to' and disconnected from each other. device consists of a rack E fixed upon and extending the full length of the platen bnr C .which is part of thecarrier No'. 2 and.l a, set of teeth W liked Dn each of the brackets L which are pari'g 0f These sets of teeth W arefixed in such bar Cis elevated they will engage with the rack F thus connecting the two carriers llf -l The the carrier No.2 i pas '85 tions on the bracke; IJ that when the p aten corresponding horizontal motion of the gar- .rien No. 2 the two carriers moving in com pany along the rods P and Q. On the platen bar C being depressed the teeth-W and rack -F become disengaged so that the "two carriers arecapable of separate horizont'a'l motion.

In operation -f V 1. Asheet of pa er a to become the original, is placed int ie carrier No. 1 by passing it forward'under the roller E, then up ward in an almost vertical planen front of the ribbon guide bar K and backward over the roller D, tension springs or cli s or any suitable kxloWn device being emp oyed to guide and 4keep the pa r a stretched between the rollers fD and as shown 4 and 5. It will be seen that the papershelf or directrix a ,is so 'constructed and arranged as to Tinsure proper insertion of work. )2. A sheet of pa is placed inthe carrier No. :2 by passing Vit fol-, ward alon la directrix or paper-table b', un-

the outer side of the endless i the carbonribbon 'inserted between tliexnto be presentedin successive contact atand in imediately behind the typing point of the ty` writer lso that on a type key being struckt `1e type will imprint a character on the erigir' nal sheet a and produce a carbon impression on the copy sheet b.

' behind the original sheet so that. on a' type type will imprint-a' ..orderon the .copy'scomparedwith the Larmes 4. To type on the original sheet a without giving a carbon impression on the copy sheet b it is necessary to depress the roller B and the platen bar C which causes 'the carbon ribbon and the copy sheet to be lremoved from contact with the original sheet and' the platen bar C to be brought into contact with the original sheet a immediately the typing point of the typewriter. T he platen bar C then provides the.. necessary solidity key being struck the character thereon but lill notgive'an pression elsewhere.' l

5. To obtain similar, l'condensed or/.extended spacing originalz-l.

' '7, To obtaln onone copy sheet b a" sum- 'mary of particulars extracted from numerous originals it is necessary to 4retain the copy sheet b, in the carrier N o. 2 while the various originals are passed through the carwhich the selected rier No. 1, elevating the roller-B and the platen bar C only during the periods in particulars are being typed oneach original sheet a'.

8. To'obtan duplicate of either oiginal or copy,' it. is necessary to insert in the pan ticular carrier and behind the originalA sheet or copy sheet an additional sheet of paper and a sheet of carbon paper-in the manner conunonlyemployed at present.

9. To 'type on any selected point of the 'riginal sheet aand obtain a carbon impresion/on any selected point of the copy sheet ,"lt 1s necessary to present the selected points at and immediately behind the-typing point of the type writer.- This is' do'ne by disconnecting the two carriers and sliding each horizontally until the .selected4 points are in vertical line directly behind -the typ-'.
