"tra Boonen? To all u-Itorn litmayA concern: g Be it known that I. Rov D vxronn Pannen. :t citizen of th. United states of America. residing m ttt-sheath the county ofOrauge. State ot' N ew York, have invented a new and 'useful Y Type-Writing Machine; and l do hereby' declare the following to be a t'ull, clear. and exf n -act description oi the same.

The present invention relates to typewritiug machihes, es ciali visible writinv" machines, and the Pe Y s especial object thereof is to provide a form of machine in which theQplaten or surface whereon the pape-:is held is automatically operated to commence a new line andk without requiring the operator to touch said platen or the carriageY or frame supporting the same.

Prior to my present invention. ity has been proposed to provide a typewriting machine having the platen horizontally disposed, with means usually' controlled -from the keyhoard for returning the platen (or carriagec rame carrying the same) toga common printing point and for advancing such platen to present'the paper for beginning a new line. A Y

My invention, however` contemplates a form of mafv chine wherein the platen is disposed preferably vertic'ally and operatesfalways in the same direction and without. the neceity of returniugto begin a new line.

i f The typewriting machine devised hyk me and em' bodying my improvements in the form shown in the accompanyimgdlawings; includes a platen which is vertically disipar! :md arranged to rotate about a vertical axis. The piper is preierahly secured and clamped around the'platen. and the machine is provided with pms whichicause the vertically-disposed platen to move step-by-step always in the samedirectiou and*r g 12= 13 and 14, andgthe'exterior handle l5 may housed. f The teeth of wheel are in nit-sh with teeth oi-a smaller upon completion qt' the rotation, to move upwardly to prjent the paper for beginning a new line of print. By Y machine frame and partssupported thereby; Fig.l 3 is a 1 vertical section (from one side to the other )4 ou the line Z-LZ ot Fig. 1?' of said machine; I` ig. 4 is a detail of the inlEing-ribbon winding mesura:` F ig. tespccially illustrates the latch for controlling the same; Figs. 6 and 7 are sideand front views of part ot the escapemeitt de vice'controlling the lengthwise advance o the platen, and for regulating tlie extent thereof: Fig. 8 Ais a' detail,V showing the frame'operated by the various keys otfthe key-board, the ribbon-vibrating device being shown connected therewith; Fig. 9 is a view partly sectional o the platen, its Vaccessoriesand the platen frame; Figs 10 and '1 1 are-A," respectively, lop and cross-semional l 'i j Specification ofLetters Patent. t

The-'wheels lo and l? are connected with the same axle 1S, which is slidnhly mounted in the sleeve-block 19, und normally' held in raised position kby aspriug surrounding axle `1S and pushing upon the underside o wheel l?. The points or projections of r@thela'st-natmgd wheel are engaged hy 1t is obvious that whenever the dug-arm 2i) is vibrant ed (and it will, as hereinaflerexplained, lit-'moved every y time there is a normal operation of a typo-har or .space har) thev wheels 17, 1li aud -7, will be allowed to travel forwardly one space under inllucnceof the spring train l0. 9, 8.`

The tnovernentuoi wheel are transmitted to the vertical rotative bar 4, and l prefer to connect the said har and wheel (at, say, 2l)` hy means which permit. I

Itt the `drawings too Y purpose hereinafter described.

ln Fig. 15, l h-ve shownmeans for effecting the independent drive mentioned. ,21 isacylindrical 1 the liar to hm e indipendent movement.,.as and for the `V5 partprojecting upwardly. and hored downwardly to receive a bar 22 having an upper end squared or otherwise non-rotatively engaging the lower end of bar 4. and havingits lower end 28 rotatively journaled in the borc of part '2l'. At its upper end, the vbore carries a fixed inserted ring 23.1hrough which` the barili! may `treely rotate, and which is provided with teeth 26. vRotativelyarranged withinv the bore,"and slidably ,though'non-rotatively engaging the squared part of n liar 22. is the ring 24 having teeth 27 and pressed'nto yielding engagement. with the ring 23 by means of a spring 25. yUpon examination of Fig. l5.'it will be seen that the part 21 will communicateitsv movements topart 44, by engagement of the teeth of ring 23 with f v i 2 5 fecting thc sante result, and which permits movement of rod 4 either forwardly or rearwardlyr independently of the4 toothed wheel 7 whendesired. In this instanfcA the part 21" is bored as before described, and is provided with a tixed'rng 110 havingteeth 109. .t squared rod i 30 107, connected directly with knob `106. extends'slidably downwardly .throughthe bar 4, and at `its lower end it carries a block 108 having'teeth engaging the teeth 1090i ring l0. and yieldingly held thereto bythe spring -1 11. Since the `lower' endet rod 107 freely rotates in 5 the ring 1l0`and since the block 108 freely rotates in the i bore of part 21, it follows that upon slighdy pressing downwardly on knob 106', the block 108 will be moved from engagement withring 110, `and the rod 4 frn'ay he freely moved in either direction to any extent desired: '4,0 while normally the said block and ring will be clamped together and the movements of wheel 7 positively conv tributed to bar4. n n .t 4 i The typewriting machine is provided with a cylindrical platen 29, disposed vertically-as shown in the drawings, and surrounding the bar y4. The engagement of the platenand bar is such that the platen while` freely slidable lengthwise of the bar, is compelled to rotateA in unison therewith. Any suitable constnlc- 'tion for accomplishing such result ymay be employed.

' `5() and I have shown (see especiallyFgs. 9, 10, 11 and l2) tlie rod 4 as non-circular, and the platen as being pro vided with end hubs 29and k29" which have axial .openings corresponding to the exterior of bar 4'. Stich construction,l it-will be obvious, will result in giving tothe platen every movement given to the bar. The

cylinder's movements lengthwise of bar 4 under the influence of the operation of the machine are upwardly,

and for controlling these movements I provide a frame comprising top and bottom plates 30 and 31 with which i the platens ends yor heads arisuitably rotatively engaged, andr which freely slide lengthwise of a guiderod 32 connected at its lower end to anarm 3P extending forwardly from the upright 3 and at its upper endy connected witltthe overhanging upper end 5 of said upright (see Figs. 1, 2, 9, 10`and 11). :The frame referred to also' comprises a'vertical racl`har lOl, the use oi which will be hereinafter explained. YIn order tocause the frame (and the carried platen.

to move upwardly. KI' provide a strap or a metal hand 33, one end'of which is connected to the lower part ot` `To plished hy striking; the finger-keys, and causing the dog 20 to release thewheels 17, 16 and 7 step by step. whereby coi-responding step by step rotative movcmentsfare given to the platen: in my 'llustratcd typei writing machine theflength of the i around the piaten, not lengthwise of the same.-

The means by which the'fnger-keys exercise such i control. will next be described. Key-levers 37 and 3S l arepivoted,y in anysuitablc manner, to vibrate, and

rest upm the upper and lower bars 36* and 36 of a suit- 9o y able fnnne tFig. 8) whose side bars are arranged to i slide f sec Fig. 3 in groovcs 125 and 126 n the sidi plates 2 of the hase. Said frame' is provided with a downi wardprojcction 35 which engages (eee Fig. 1) thc dog' 20. Whenever. therefore, a key-lever is pres-smi thc 9ol fmmc 30 and 3G is pushed downwardly and.` noon release ot" said key the frame is. raised by tlnsprinv :Il connected with dog '20. The ribbon-vibrator spring also, as hereinafter described, assists in such return of thcfmuie. v f j In order to dispense with shift mechanism, l prefer to provide themachine willi a double key-hoard of which tlw key-levers 37 may represent the upper case whiltl thel key-levers 38'represent the lower (use. Ther machimis alsoV provided with two sets ofv type urranged to strike at the common printing point. 43. y n Key-levers 3S are show Ats'eonntwtcd by rods 321 with type-hars 41 and types 45. and key-levers 37 `are shown as connected by rods 40 with type-bars and types 44.

with a vibrator plate 51. Said plate is movable in a stop 50. and is moved upwardly against a spring 52` 115 I vone `end of which is connected to said stop andthe I other end 53 thereof is connected with o. shoulder or'- 'bent portion ot' the plate. The plate is prorded at its upper end tset- Fia. 3) with lingers 55 for holding the ribbon in position. The operations of lthe key-levers 37 and willf therefore. :ult in vibrating the ribbon (by raising and lowering the ame) to and from in front.; of kthe printing point whenever a type. is to be imprinted. Two spool` 57. 58 (Fig. 3) are provided and the ribbon 56 winds on to one of :oid spoolsas it nn- 12.5,.

lwinds from the. other. Spool 57 is driven byyrod 59, and spool 5S is driven by rodO. Rodv 59 carries-bevel wheel 01 and this is engaged by either wheel 63 or wheel 64 according tu the desired direction of travel ofthe ribbon. Rod 60 carries a bevel wheel 62 which 130 ine of print is s.

Near to each ot' said wheels tht-shaft titi mrries thy means ot' elatnping screw-sra spring tooth or pawl |38. ,It will be obvious that the oscillations ot' the shaft liti qdne to vibrations of key-levers) are transmitted. by the tneansdeseribed and sltown,`as step by step movements tothe inking-riblmn. t j n The ribbon spools may he ntoved to any extent desired. by'tneans ofthe artt: 69 and handle T0. which'Y are employed tozlirst slide the rod so as to havethe i wheel Ii-l engage wheel 6l andthen to rotate the rod 59 and spool 57.f C

The keys t'or the uppercase ot' the machine are repre-` sented at T l and those t'or'the lower case are represented v f at 72. There may he as many of said keys as desired. f In addition. I have shown the maf-bine asbeing provided with a tabular key 73, a new line key74, and a .spare lrar TT. i i' f vThe tabula: key vibrates a lever 76 (see Fig. lili` |whit-lt rests upon the bottomk bar 36 oi the l'mme. and is .provided with two tlownwardly-extending projections or stops 79 and 80. The positions ut' said projections are shown in Fig. .1, the projection T9 being he.-

platen-and two smaller rollers, and the paper is not lockedintoengtgement with the platen. A

Itimy improvements, however. I have found it advantageous to fasten the paper around the platen. in

such manner as to make it unnecessary io\r the'opent- 100 torto reinsert or touch the paper until the letter cont- Apleted or the page is filled;

Referring to Figs. 9 10 and 11, it will be seen that l' fhave `shown the platen as provided with attachments whereby the paper is wound about the platen and grippinglyheld at or near its twoside edges. Within the platen and extending longitudinally kthereof I provide a curved v plate or jaw 199, secured at top and bottom to a.` rod 198, and normally held by f. y a spring against the walloi the recess of the platen. 1,10

The rod is provided. at its upper endgwith a fingerpieee` 134. and upon manipulation of, tid linger-piece.`

the curved plate 199 is swung awa) liront the platen sufficiently to permit one' sideedge'o the paper'to he 'evt-lily inserted. whereupon theplate-is released and 1,15

Said rod is provided with vattoutwardly extending'nger-gripping portion 144 midway of its length. and also carries long and narrow rollt-xs 141. The .ends vof rod are connected hv 125 springs 13S and 139 with the plates 136 and 137. near the pivots thereof. Otte side edge ofthe paperv having been gripped-.as aforesaid, by the plate 199. the operator gntsps the part 144 with one hand, and re pt-atedly pressestho tabular key 73 (Fig. 1) until the 130 ...mt-M

The machine isl provided with a scale 150 (Figs. l and 3i curved around and made fast to the upper end of the f platen. and with a pointer 152ml plate 151 whichv is connected with the arm 30 of the platen-carrying haine. By consulting the pointer and salc, the op;

: crator will always be able to ascertain the exact point of a line whereat. the nexttype will print. v'l'he numerals on. the scale 150 will preferably correspond, so far as relative position tothe axis of the platen is concerned. 'with the previously mentioned scale 82 upon'` the uppet face of wheel 7. v t

I have also provided a.k second pointer (see Fig. 3),` which will indicate the exact line, or pointv lengthwise of the platen, whereat the next typewill print. For this purpose, I may use an elastic metal strip 153 fastened at 154 to the body-oi the machine and having a pointed 'end 155 indicating the common printing point for the machine. n f
