T0 (all whom t 71mg concern:

Beit known that I, CHARLES E. MAXWELL, a citizen of the TJnited States, residing at Vollaston, county of Norfolk, State of Massachusetts, have invented an Improvement in Type-Writers, of which the following description, in connection with the accompanying drawings, isaspecilication, like letters on the drawings representing like parts. My invention relates to type-Writers, and especially that class of type-Writers that arev adapted to write nponaplain surface-such, t'or instance, as the page of a book.

Heretofore, s0 far as I am aware, all socalled bool; type-writers are of the typebar kind; and it is the object of my invention to constructa type-writer adapted to write on the page of a hook wherein a type-wheel is used instead of type-bars, the type-wheel being preferable, because 'a type-wheel typewriter is capable of more accuratealinement than a typefbar machine. My invention comprises a base upon which is slidably mounted for movement longitudinally thereof a carriage, the said carriage carrying a printing mechanism and its supporting-frame, the said printing mechanism being movable upon the carriage transversely of the base. The printing;n 'mechanism includes a t vpewheel,upon the surface of which the various characters and letters are placed, and suitable type-wheel rotating and vibrat ing mechanism, together with means operated bythe type-wheelvibrating mechanism, to advance the printing mechanism to form the space between veach Vletter or between the words. The space between the lines is made by advancing the carriage bodily toward the front of the base by means of a line-spacer consisting of 'a key-lever mechanism.

In the ordinary typelwheeltypewriter the type-wheel has a cylindrical surface, upon which are a series of circular rows or fields of type-as, forinstance, small case, capitals, figures, and symbols-such cylindrical shape` of the type-Wheel being operative, because the paper rests upon a cylindrical platen or surface.

In adapting a type-wheel'or printing upon a plane surface it isnecessary either to place all the symbols or characters upon a single lcld orzone on the .surface ofthe type-wheel wheel of the latter class, which is constructed so as to have on its surface a plurality of type zones at diierent angles to the axis of rotation of theV type-wheel, andsuitable mechanismiis employed to bring any one of the type zones into operative position-that is, into such position that the type on said type zone may be impressed upon the paper, and this without having any of the type in the other zones broughtin contact with the paper. For this purpose the type-wheel is pivotally attached to a suitable vibrating arm, so as to be capable not onlyof rotation aboutits lon gitudinal anis, but also capable of swinging about a transverse axis,.tl1e movement about the transverse axis operating to bring any one of the type zones into operative position or parallel with the paper. The movement of the type-wheel `about its transverse axis is controlled by suitable key-lever mechanism. K Referring now to the drawings, Figure l is a plan view, with portions of the mechanism broken away, of a type-Writer embodying my invention. Fig. 2 is a section on the line :c a', Fig. l. Fig. 3 is a detail showing the mechanism for bringing any type zone into opera-l tive position. Fig. 4. is a section on the line 4 4, Fig. 1, looking in the direction of the ar row. Fig. 5 is a section on the line 5 5, Fig. 1,looking to the right. Fig. 6 is a section on theline 6 6, Fig. 5. Fig. 7 is a detail herein after referred to. Fig. is a perspective view of a portion of the mechanism. Fig. 9 is a detail of the vibrating arm and rock-shaft to which the type-wheel is pivotally connected. Fig. 10 is a detail of the mechanism shown .in

wheel mechanism. Fig. 13 shows a modified form of type-wheel.

The base of the machine is designated gen- `erally by 3, and this is pivotally connected at one end to a suitable standard, comprising the fixed uprights 4, which are connected bya suitable rod 5. The rod 5 may be either telescopic, so as to permit of its being extended to span both .pages of a bookon which the type-writer is to be used,or the said rod maybe solid and of sufficient length to reach across Fig. 3. Figs. ll and l2 are details of the type- ICO 1o ineens, as by set-screws 9.

so ily upon the rod 3o together at one lil 5 nested to the rod 7 at one end of the base 3.

The rod 5 may be provided With suitable adjustable stops 8 for the purpose oi' preventing lateral motion of the base 3, lthe said stops being secured to the rod 5 by any suitable it' desired, the links 6 may be clamped to the Arod 5 by the means illustrated in Fig. 2, which consists of the bolt passing through the two members of the link and having the arm 10, provided with r 5 a screw-'thread aperture for clamping the loop of the link to the rod `With this construem tion when one page oit abook has been written n pon by loosening the clamping devicelO and the stopcollarsS the bese may be moved bodand shifted sideivise into position over the other page.

The bese 3 is preferably made extensible, whereby the typewriter m ay be used upon ditferent-sized books, if desired, and .said base comprises the outer Ushaped section il., having the two side pieces and the front portion l2, provided with a suitable finger projection i3, and the inner U-shaped section 14, the two side portions ofthe section 1li being connected end by the rod 7 Referring to Figs. l and 5,it Will be seen that the side pieces of the section ll are slotted and have the base-flange 15, which rests upon the paper or book, :virile the side sections il are provided with means forl adjustably securing the two sections together-such,for1 instance, as screws 1,6, Whiclrpass through the slots in the side pieces ll and screw in the side' pieces le. Each side'piece lli is pro-l 40 vided with the inwardlydisposed rib 17,

which serves as a guide for theY carrisge C,

upon which the printing mechanism is sup,

ported. The carriage() comprises the two .runners 18, which are suitably guided by the rib 17 and the bridge-piece 19, connecting said runners, the bridgezpiecetforming a support upon which thev printing-nechanism i'rame is carried, as hereinafter described. The run ners 18 are shownas comprising sin upright 5o portion, which is fastened at its upper end in any suitable way to the bridge-piece 19 and at its lower end is bent' inwardly, as vaff-120,

y sind e'vtendsunder the rib i7, (see Figs. i and 5,) thesaid rib and cooperating liangsilop'- erating to hold the carriage iirrnlyupon the baseandyet to allow its having a sliding motion thereon. y

The'li'nefspacing mechanism. for sdvanciner the carriage will be hereinafter described.,

The px'intixiginechanisn1 frame, which. is supported'upon the bridge '19 of the carriage C, may be of any' suitable construction adopt ed to support' the operative parte of the print ing mechanism, end itis shown es having exi-- tending acros'sthe' sanielcentrally thereofv the angieebars 2l, on which are mounted suitable friction-rollers {22,'ivhi'ch rest' against the ynesting the runners ztgrpebeooneaved in order tont t soeces.

The Aprinting mechanism illustrated is that of a type-Wheel mechanism, the type-wheel being supported upon a rocloarin, which is given its movement by means oli two vibrating sectors, as usual in type-writers ofthis class.

inasmuch as the typewriter herein fle- .scribed is adapted for writing on pinne or let surfaces, it would be impossible to use atypewheel having a plein cylindrical surface upon which. were a series of rows or fields of type, for when the type-wheel was vibrsted to make an impression upon the paper one of the characters in each of the iields or rows ol' type would Contact with and leave an impression on the paper.

My type-wheel instead of having a cylindrical surface has on its exterior a plurality ot' what l terni type zones, cach type zone having thereon cert-ain characters or symbols, and preferably one zone would have the small type thereon", another zone the capital letters,

and a third. zone iigures or symbols, although this arrangement is not necessary. Each type zone has a different ,angular relation 'to the longitudinal axis of the wheel, and the Wheel is pivotally mounted upon a transverse axis, and suitable mechanism is provided for swinging the type-wheel about such transverse axis," whereby any one of the type zones may be brought into operative position-that is, in such position that when the type-wheel is vibrated the symbols or characters in such zone will strike the paper squarely.

Herein i have illustrated a type-wheel; but it will be obvious to those'shilled in the art that a typeshnttie such as is used in the wellkuovvn Hammond typewriter might be ernployed instead-of a typesvh'eel, such a inediiied form of type-Wheel being illustrated in Fig. i3, ond l1 desireit understood that herein the term type-wlieel is used in its broad sense es including either a type-Wheel of the class shown the main views ci the drawings or a typeshuttle, as illustrated in Fig. 1S, or any other device wherein the type are leil arranged upon a single rot-stable support.

surface of the platen; but in my type-Writer, wherein I Write on a plane surface, I make the face of the type flat, so that each character will besquarely impressed on the paper.

The type-Wheel is designated by 26, it having on its surface a plurality of type zones, as above described, and being pivotally connected to the vibrating arm 27 in a manner hereinafter described, the arm .27 being fast at one end in a transverse aperture in the rockshaft 28. (See Figs. 7 and 9.) The said rockshaft 28 is sustained at each end upon suitable pivot-pins 29 by having concentric sockets bored in the ends of said rook-shaft in which the ends ofthe said pivot-pins rest, as plainly seen in Fig. 9,the said pivot-pins being suitablysupported inthe printing-mechanism frame, the frame for this purposehaving the depending arm 30,through which the said pins pass and in which'they are supported, the ends of the pins being supported for rotative movement in any suitable Way in the-side members of the printing-mechanism frame. i The rockshaft 28 has sleeved thereon the hubs of the sectors 3l, which sectors have gear-teeth meshing with a pinion 32, loose upon the rockarm, said pinion having mechanism connecting the same to the type-Wheel, whereby rotation of the said pinion is transmitted to the type-wheel, as is usual in this class of devices. The rocking of the sectors 31 is accomplished by means of the usual hails 33, which .are

pivotally mounted .upon the bar 34', there be-` ing one bail for each sector 3l, as usual, each bail having an arm 35 integral therewith and projecting therefrom,` which arm has at its end the gear-teeth 36, meshing With coperating'gear-teeth upon the respective hubs ofv the sectors 3l, this constructionbeing common in type-Wheel type-writers. The' bails are operated by the usual keylevers, which are fulcrumed upon the rod 34 and are mainrss tained -in their inoperative or raised position by means of the usual springs 37. A second bail 39, extending clear across the printingmechanism frame and also pivotally mount-v ed/upon the bar 34,' has an arm 4Q connected theretocentrally thereof, said arm being also' pivoted vupon the bar 34 and-having at its endv geaIg-teeth which mesh with gear-teeth 4l upon `^a sleeve-l2 on the rock-shaft 28 .between the hubs of the 'two sectors, which sleeve carries a locking-arm 43which coperates-With the heart locking-Wheels@ integral with the pinion 32, this locking mechanism for the type- Wheel being of familiar construction. Ines-- muchas the sleeve upon whichfthe locking-l arm 43 is mounted has a motion .around thelshaft 28,1 provide the said sleeve with oppl sitely-disposed slots 42'-, through which the vibrating arm 27 extends,these' slots permitting the said vibrating arm-27 and-the shaft- L2` to move independently of the sleeve'42. ltr/ill ofcourse beohviousthat each keylever will have directly`over the bai139. a notch Mot-.suitable depth, so that'the-bail 33 will be' operated t'o bring the'desired charac- 'into operative engagement with the heartwheel.

It will be understood, of course, that suitablespring mechanism may be employed to return the bails to their normal position as l i soon as the depressed key has been released, such springs acting through the baile to raise the type-wheel from the paper. I may, if desired, provide suitable springs 29' to assist in this operation, the springs being-shown as surrounding the end of the rock-shaft 2S and as fast thereto at one end and at the other end to the sleeve-hub of the sectors 3l. These springs 29 Will operate to return that sector which has been depressed farthest back into its normal position, even with the other sector, and the spring mechanism underneath the hails will operate to throw both sectors and the type- Wheel back into their normal osition.`

Further description of the type-wheel rotating and vibrating mechanism is not deemed necessary, as such mechanism iscommon in this 'arti As usual in type-'Wheel type-Writers, a suitable ink pad or roll (or ribbon, if desired) is provided, against which the type-Wheel contacts just before it strikes the paper, said inking-roll operatin g to ink the letter or character which is to beimpressed upon the paper. In this invention the usual ink-,roll 150 is shown as'mounted upon the pivoted arm 151, which is suitably cbnneoted to the frame of the printing mechanism, said arm beingcontrolled by the spring 152, as usual.

Preferably theyoke 47, which supports the typewheel,as hereinafter described,will have al transverse member or shield 70, against which the inking-pad rolls when the. type- Wheel is fully depressed.

` As stated above, the type-Wheel has onits surface a plurality of type zones, and in `this embodiment ofi my invention the said type zones are 'represented fby Y cylindrical and j-conical surfa'ces,there beingthree such zones, designatedby c, @and c, respectively. a type-.wheel of the style shown the iiat face fot the type will vbe approximately parallel to the zone surface. I wish it understood, however, that I may make the surface of the type-Wheel in the shape of a sphere or in\any othershape, provided .the faces of the type `:themselves 'are dat in all instancesl- Inorder. ,to-bring any one zone into' operative position, lthe said type-wheel'is-mounted upon anaxis :transverse-toits longitudinal axis, one convenienthvay of .thus mounting the type-Wheel 'being shown', wherein a-frame'or yoke 47, hav- ;ing a 'spindle 48 projectingtherefrom and' upon which the type-Wheel is vmounted for rotation, has the ends of vits arms pivotally connectedjto the armsiof a yoke 4 9, which is, "fast uponythe vibrating arm 27,-the yoke-.i9 being'illustrated asbeing connected to the" said vibratin'garm 27 by the f'goos'e'neclrl 50,

"o Averse aXis.

' arms of the 'yokes 49 and t7 are illustrated as being on a line approximately at right an- 5 gies to the longitudinal axis of the type-wheel and central of said wheel, although this is not necessary, as the transverse axis upon which the type-wheel swings might be either side of the center thereof. One of thearms of the yoke 1o 47 has projecting therefrom an offset 5l', to which is connected alink 52, said link being given a suitablelongitudinal movement by a suitable key-lever mechanism, hereinafter described, to turnthe type-wheel about its transverse axis 51 for the `purpose of bringing either of the type zones into operative position. As illustrated in Figs. 2 and 3, the central type zone bis the operative one.

The key-lever mechanism for turning the zo type-wheel about its transverse aXis will now be described, referring particularly to Figs. 3 and 10. A key-lever 53 is pivotally mounted, as atv54, uponuhe printingunechanism frame and has connected thereto the link 55, which is pivotally connected to an arm 56 upon a sleeve 57, carried by the pivot-pin 29 for the rock-shaft 28. The sleeve 57 has at one end a flange or disk 58, which cooperates with the iiange or disk 59 upon a sleeve 60, 3o also carried by the pin 29, the disk 58 having a shoulder which engages a projection upon the ydisk 59, so that the forward rotation of the said disk 5S is communicated to disk 59; but the said disk 58 and sleeve 57 may turn back into their normal position without affecting the disk 59 and sleeve 60, a spring 57 being provided for returning them to their normal position and a similar spring 60 acting simi- ,larly for the sleeve 60. The bsleeve 60 has 4.o the arm 6l integraltherewith, the said arm beingconnected to the arm 62, pivotally mounted upon the pin 29, and the arm 62 is in turn connected to the link 52. By means of this construction it will be seen that when the 45- key-lever 53 is depressed the'link 55 will op-r erate to turn the sleeve'57, and through the .mechanism described and illustrated in Fig. l0 give to the link 52 a vlongitudinal motion to thereby turn the type-wheel about its transf, A suitable stop-pin 63,1nadc fast to the printing-mechanism frame, serves to limit the depression ot' the key-lever 53, and any suitable mechanismmay be employed to lock the said lever in its depressed condition,

j 5S S0 as to hold the desired typefr'ione in operative position.

Assuming that the type zone a, is that containing the small letters, it will be obvious 1that mechanism must be employed to bring 6o either-,the type zone 'c or Z) into operative po- '.sition', and this is accomplished by providing 53 with ateupplemental key-lethe key-levery ver 65, pivotal1y connected thereto, as atf),

and resting upon a pin oraprojeetion 67 ,.fas-t upon the main ,keyflever 53.l

employed to limit pleinental A stop-pin GT3' is.y the depression*r of the supkey-lever 65 the stop-pin 63l `being slightly longer than the stop-pin 63. With this .construction it will be obvious'that to bring the type zone ZJ into operative position the key-lever 65 isused, the said key-lever by means of its ver 53 operating to depress the same until it strikes the stop-pin 63'.

When the type zonec is to be brought into operative position, lthe key-lever 53 is depressed `by its key 53', and as the stop-pin 63, copf, erating therewith, is shorter` thanthe stop-pin 63 the said key-lever may be depressed` suf-` ciently to bringV the type zone c` into operative position.

As stated above, the type-wheel is'rotated ,from the pinion 32 by means of an arm, the `'said arm being designated by 67, and -it having a universal -joint connection with the type-wheel, such connection beingnecessary because of the movement of the type-Wheel about its transverse anis.` One convenient way of making`- this universal jointis as illustrated in Figs. 11 and 12, wherein the arm pinion, is slotted, asat 68, and the type-wheel is provided with the pin 69, having the reduced portion which plays in the slot 68.

It willbe obvious,of eourse,that other forms' of universal joint may beemployed, if desired.

' It is sometimes desirable to limit the movement of the type-wheel about its transverse asis, and this is conveniently accomplished by providing the yoke 47 with the transverse guide-piece 70 or shield, said guide-piece or shield having shoulders or stops-71 thereon, which cooperate with a shoulder upon a .spring-arm 72, fast to the gooseneck 50. The shoulder 7l and the shouldered arm 72 cooperate to limit thesvringing movement of the type-wheel about its transverse axis in an obvious way.

The mechanism for producing the spacing between the letters and between the words comprises a toothed bar fast upon the carriage C and a reciprocating pawl engaging the same, said reciprocating pa-wl being connected to the printing-mechanism frame and being operated b oth by mechanismcommon lever, whereby'I the pri ating-mechanism frame impressed upon the paper and also may be advanced independently by the space-bar.

The bridge 19 has fast thereto at its under side the toothed bar Aand the printingmechanism frame su'pports the reciprocating feed-plate 91 in any suit-able Way, said feedplate projecting at one end beneath the bridge 19, as seen in Fig. 2, and havingv pivotally connected to such projecting endthefeedpawl 93, said pawl having a tooth 94 to en' gage the notches of the bar 90 and eing held in operative posi-tion by suitable s rin-g4 95. The feed-plate is provided with a slot 96, through which projects one end of an operating-lever 97, said operating-lever being pivotally connected to a `bracket 98, fast upon to all the key-levers and by a separate space` is advanced one space each time a letter is connection with the key-le- 67, which has a pivotal connection with the the front comb 99 of the printing-mechanism frame and having the arm 100 projecting therefrom, which is adapted to be operated by the locking-bail 39, the bail for this pur- .pose having aslot cut therein; in which the .Y projection 100 normally plays, as best seen in Fig. S.' With this construction it willabe obvious that when any key is depressed the locking-bail 39 will operate thel projection .,100 and swing the lower end of the operating-lever 97' toward the front of the machine, thereby moving the feed-plate 91 in the same direction and allowing the feed-pawl 93 to l click into the next notch in the notched bar 90.

A suitable spring 101, connected to the' printing-mechanism frame, bears against a engaging the notched bar 90 will operate toadvance4 the entire printing mechanism into position to impress the next letter upon the paper.

A stop-pawl 103, pivotally mounted upon 4 the printing-mechanism frame, operates to engage the notches in the notched bar 90 and prevent any backward or retrograde movement of the printingmechanism frame.

separate space-bar independent from the other key-levers is provided for making the spacesbetween the words, such space-bal being designated by 105 and having at one side thereoi` the cam projection 106, which bears upon the upper portion ofthe operating-lever 97, as seen in dotted lines in Fig. 8. By depressing this space-lever 105 it will be obvious that the printing mechanism can be advanced to form the space between the word without operating the type-wheel,

The line-spacing mechanism is carried by the printing-mechanism frame, and consists of a key-lever mechanism in operative connectfion withl a gear wheel or pinion upon the gear-wheel meshes with a i rack-bar upon the base of the machine.. As

illustratelftherib `17 ing with the gear-teeth upon the rib 17.

(see Fig. 4) is provided with geariteetirupon its upper surface, and hence operates as arack-bar, and the carriage C is provided with a transverse shaft 80, which has fast thereon a gear-wheel 8l, mesh- A suitable pawl-and-ratchet mechanism isused to intermittingly rotate the gear 81, said pawland-ratchet mechanism the key-lever mechanism upon the printingmechanism frame. One convenient arrangement of this pawl-and-ratchet mechanism is illustrated in Figs. 4, 5, and-(5, wherein the gear-wheel 81 has fast thereon the disk S2,

provided with a milling-surface, and thus'operating as a ratchet-wheel, and the shaft SO has pivotally mounted thereon an arm S3, to which is pivotally attached a pawl 84, which being controlled, by*

cooperates with the "milling-surface of tl1e disk 82. a sleeve'1l0, which is rigidly7 connected to an arm 111 afor turning movement about the shaft 80, 'the said arm 111 having the olset portion 112, which engages the end of the pawlSl, as seen in Figs. 4 to G. It will be obvious that with this construction whenever the sleeve 110 is turned about the shaft 80 the arm 111, through its odset portion, will rock the pawl 84 and bring..its nose into engagement with the milled surface of the disk S2, when further rotation of the sleeve 110 will operate to turn the gear-wheel 8l, and thus advance the carriage C.

Forihe purpose of turning the sleeve 110, which sleeve is in the nature of a roclcshaft, the said sleeve is provided with a longitudinal projection or iin 115, which is engaged bya reciprocating rod 11G, operated by a suitable key-lever having a projection 117 depending therefromfwhich is pivotally connected to a lever 11S, to the end of which the rod 116 is pivoted, the lever 118 being pivotally connected in any suitable -way to the printing-mechanism frame. rod 116 which engages the dn or projection upon the sleeve 110 may be enlarged somewhat, it desired, so as to have a firmer bearing upon the edge of said projection. 'With this construction the depression ofthe proper key-lever will, through its projection 117, operate the lever 1.18, and, through the rod 116, turn the sleeve 110, which sleeve, through the mechanism above described, will operate to turn the gear-wheel 8l, and thus advance the carriage.

The projection 115 extends the ful-l length of the sleeve 110, and the end of the rod 110 has-a sliding engagement therewith, so that an operative connection between the linespaciug key-lever and the gear-wheel S1 is always maintained, regardless of the position of the printing mechanism. It will thus be seen that I have provided a linespacing mechanism consisting of a key-lever device upon The end of the The shaft 80 has mounted thereon "3 ICO the printing-mechanism frame, this being' quite an advantage,because the said linespacing mechanism is easily operated without any reaching on the part of the opera-tor.

In order to obtain different distances between the lines, I have provided an .adjusting device which cooperates with the pawl-anct ratchet mechanism above described, such adjusting device being illustrated best in Fig..

IZO

6, wherein the arm S3 is shown as projecting beyond the shaft 8O on the oppositepside, as seen in dotted lines at 120, and the bridge 19 of the carriage C has secured therein the adjustable screw 121, the said screw having the checknut 122 for locking. it in' any adjusted position. A spring 123, secured at one end to thearm and at the other to the bridge 19 of the carriage, serves ,tofreturn the arm 83,

and consequently the pawl 84, to its inopeiw ative position. It will be evident that by ad- 10.
