TYPE-WRITING MACHINE.

SPECIFICATION forming part of Letters Patent No. 357,878, dated February 15, 1887. Application filed January 30, 1856. Serial No. 190,344. (No model.)

To all whom/ it may concern:

Be itknown that I, JAMES H. WAITE, of Orange, in the county of Franklin and State of Massachusetts, have invented certain new and useful Improvements in T'ype-VVritingllIachines, of which the following is a full, clear, and exact description.

This invention particularly relates to that class oftype-writing machines in which an imprint from the several type-charactrs-such as letters, (capitalandsmalh) marks of punctuation. &c.-with which the machine isprovided is secured with the use of a stylus, which, by the operator, is changed about upon the machine, and being located at any one of a series of certain defined points, all preferably properly marked for identification and distinction one from the other, and in accordance with the type-characters used in the machine, is then and there made, by the operation of it and of the other parts of the machine properly arranged therefor, to secure an imprint of the type-character corresponding in character to that represented by the point, ofthe series of said points, at which the stylus is located and operated.

This invention, however, in some of its parts or features, is applicable to other classes of typewriting machines, as will fully appear from the description hereinafter given thereof.

The particular features of this invention, in substance, consist- First, in the combination, with a series of type-characters arranged in a circle at equal distances apart and carried by a common rotating holder having its axis of rotation coincident with the center of said circle of typecharacters, and with a perforated indicator or plate having a series of holes through its thickness arranged in a circle at equal distances apart, and the center of this circle coincident with the axis of rotation of the rotating carrier common to said series of type-characters, (said so arranged typecharacters and said perforated indicator being located in parallel planes) of a frame which is placed between said series of type-characters and said perforated indicator and there arranged for a movement forward and backward between them, in one direction against and in the other with the reaction of a spring, and which in some parts thereof extends in a circular line coincident with the perforations of said perforated indicator, and an imprint-pusher which is arranged to press upon the typecharacter of said series of typecharacters in line therewith and in a direction to secure an imprint thereof upon the paper properly presented therefor, the type character for such imprint cooperating with an inkribbon interposed between it and the paper, 810., on which the imprint is made. The said operation of the imprintpusher is secured by the movement of said forward-and-backward moving frame, and the same is produced by insert ing a stylus in a hole of said perforated indicator and then pressing the stylus through said hole and against the part of said moving frame in line therewith, thereby moving it (said frame) against its spring, and through it pressing said imprint-pusher upon the typecharacter, and the type-character against the paper through the ink-ribbou.

Second, of an imprint plunger or pusher operated from a reciprocating frame by a stylus inserted and pressed through a perforation of a stationary perforated indicator, in combination with a pawl and ratchet-wheel of each of the ink-ribbon rollers and mechanism inter-- posed between said reciprocating frame or said imprint'pusher and said pawl to cause in one movement of said frame, and that in a direction to produce an imprint of a type-character, as before stated, a backward movement of one of said pawls over the teeth of its ratchet, and in the other movement of said frame to allow of a return of said pawl, which in returning partially turns said ratchet and its roller, thus securing lengthwise feed of the inkribbon to present a fresh portion thereof for the imprint of the next type-character, which may be depressed, as aforesaid.

In the accompanying drawings, part of this specification, the features of this invention are illustrated in connection with a type-writing machine of the class hereinbefore stated, and the machine, except as to the features of this invention, is constructed and provided with the necessary working parts, all as ordinarily. V

In Figures 1 to 7, both inclusive, the paper-supporting roller and its carriage in every forming a i ICO instance are in their normal positions-that is, in those positions from which they are started and moved intermittently lengthwiseso as to present, because of and after each of such intermittent movements, a fresh portion of the paper carried by the paper-supporting roller to receive the imprint of the next operated typecharacter.

Figs. 11 and 12 are views illustrating modifications, as will hereinafter appear.

In the drawings, A A represent the two main parts of the supporting frame-work of the machine. The part A, which is the lower or under part of the two parts A A", makes the support for and carries a paper-supporting roller, 13, and carriage C for said roller, and all the connecting and operating mechanism for intermittenti y feeding said carriage and roller lengthwise, for returning the carriage and paper-supporting roller, and for intermittentlyrotating said roller, and also the alarm-bell and mechanism for sounding it. The part A, which is the upper part of the two parts A A, makes the suppoit for and carries the ink-ribbon rollers D D, arranged at opposite points in the length of the ribbon E, and extending from one to the other and attached to each of said rollers; also, the mechanism for intermittently operating said inkribbon rollers to feed the ribbon lengthwise from one to the other thereof, winding the ribbon upon one and unwinding it from the other; also, the rotating holder F, common to a series of independent and separate acting typebars G, all having their several types in a circle concentric with the axis of said rotation;

also, the stationary perforated indicator or plate H; also, the mechanism for rotating the holder for the type-bars, and the mechanism for securing an imprint from a type of the types of the several typebars G, the mechanism for setting free the mechanism of the paper-supporting roller B and its carriage O, and by the operation of which said paper-sup porting roller and its carriage are intermittentl y fed lengthwise, and which said so-operating mechanism is carried by the under part, A,

of the two-part framework A A as before stated.

In the ordinary use and operation of the machine both parts of the two-part frame-work A A are stationary, and each is suitably constructed to support and carry the various devices above stated, and the upper part, A, at its rear side is hinged to the lower part, A, so that it may be swung upward and backward therefrom, and so swung supported against falling. Again. said two-part frame-work in each of its parts is constructed, furthermore, in every respect, excepting, however, in such respects as constitute the present invention and as will hereinafter appear, the same as ordinarily in type-writing machines of the class to which this invention relates, and therefore said construction needs no more particular description herein.

Again, except as to the features of this in-. vention, and which will hereinafter appear, all of the several parts of the machine before recited-as, for instance, such as the paper-supporting roller B and its carriage O, the inkribbon rollers D, the stationary perforated indicator H, and also all the several mechanisms above referred to, such as the mechanism for intermittently feeding lengthwise the paper-roller B and its carriage O. &c.are in many respects the same as ordinarily, and therefore, except as it may be necessary for a perfect understanding of the features of this invention, they will not be particularly de- I scribed.

It is well, however, to here observe that the mechanism shown, and which will be hereinafter more or less described in detail, for rotating the typebar carrier or holder F forms no part of this invention, but is the invention of a Mr. Joseph \V. Peck, and forms the sub ject of a separate application for Letters Patent of the United States made by him of even date herewith, Serial No. 190,354.

The type-bar holder or carrier F is made separate from the type-bars G, and the typebars are in separate pieces. (See Figs. 8, 9, and 10.) Each of the type-bars is flexible or elastic, and each is provided with a type-charactersuch, for instance, as acapital orsmall letter of the alphabet, A or B, 820., or a figure 1 or 2, &c., or marks of punctuation, as a period or a comma or asemicolon, &c., or-such other characters or seriesof characters as it may be designed that the type-writing machine shall be adapted to.

*A desirable combination of type-characters forthe several type-bars G, and one which, for the purposes of the machine, as shown and to be hereinafter described, consists in the use of all the letters of the alphabet, both capitals and small letters, of the digits 1 to 9, and of the ordinarily-used marks of punctuation, together with other characters, and all as generally used in typewriti n g machines; but whatever characters are employed, they are arranged in a circle concentric with the axis of rotation of the holder or carrier carrying the type-bars and upon one and the same side of the bars. The type-characters, preferably, are formed independent of the type-bars, as well known in the art of making printers types, and attached to the type-bars; but they may be formed directly upon the type-bars by the well-known process for the electro-deposit of the metal of which the types are made upon the metal of the bars. Again, each type-bar, preferably, is stamped or otherwise cutout of sheet or plate metal of a flexibleor elastic character, and one of its edges, intermediate of its length, has a notch, a, which, when the type-bar is placed flatwise in a notch, b, of a raised annular flange, d, of one part of the twopart .holder or block F, interlocks with the outer and inner edges of said flange, and thus holdsthe type-bar against lengthwise movement on its holder. The type-bar also enters a notch, it. of an annular flange, K, inside of said flange d, and it is also held against movement otherwise by clamping it between the two parts of the holder, which parts are placed flatwise against each other and in any suitable manner as, for instance, by screws or other fastening devices passed through the thickness of the two parts of the holder fastened rigidly and firmly together.

A construction of the holder and of separate type-bars G, such as just above described, allows the bars to be removed and replaced at pleasure.

The typebars and their holder, made, as above described or otherwise, so as to have each type-bar capable of separate and independent movement, are located in the machine in a horizontal plane, and the holder is axially and concentrically attached to a vertical arbor, M, turning in suitable stationary bearings of the upper part, A", of the frame-work of the machine and suitably confined against accidental escape from or lengthwise movement through its bearings. This arbor M, at its upper end and above the stationary perforated indicator or plate H, which is placed horizontally above and parallel with the horizontal type-bars G, has a horizontal gearwheel, N, rigidly affixed to it.

The series oftype-bars G, arranged as above described, are rotated by the rotation of the arbor M, and by being so rotated the type of any bar can be brought to a given and determined point or place over the ink-ribbon Eof the machine, which is arranged to be intermittently moved lengthwise under and across said so-determined point or place, traveling of the type-bars.

from one to the other of the ribbon-rollers D therefor, as will hereinafter more fully appear, and substantially as well known in type-writing machines. In this position of the type of a type-bar such type is located for animprint thereof to be made upon the surface of the paper-sheet, which is directly below said inkribbon and is confined to the surface of the paper-supporting roller B, extending in the same direction as the lengthwise movement of the ink-ribbon, and arranged as ordinarily for an intermittent lengthwise movement under the ink-ribbon and along the length of the same, and for its return at any time and the paper carried by it, either to its original or to any other position within thelimits of its said intermittent lengthwise movement.

The imprint of the type of a type-bar, as

above referred to, is secured by the co-operative action of said type and of theiuk-ribbon next below upon the part of the paper on the paper-supporting roller directly below the type, as well known intype-writing machines, the type-bar for this purpose being depressed with sufficient force and pressure therefor. Under this invention, for thedepression of the type-bar, located as above described, apusher, O, is provided. This pusher O is capable of a reciprocating vertical movement through a suitable stationary guiding-tube, I, of the upper part, A of the framework A A This pusher O has a coil-spring, l, surrounding it and confined lengthwise on it between ashoulder,-m, thereof and the lower end of the guiding-tube P. The depression of this pusher is against said spring, which, in reacting. when the pressure on the pusher is released, returns the pusher to its normal position. The location of the pusher O is always directly over and 1n the same vertical plane as the type of the typecarrying bar and of such bar as has its type brought to the given and determined point of the machine before stated.

The above-stated depression of the pusher O is directly secured through the depression of a horizontal circular shaped frame, Q, located directly above the same, and which is concentric with the axis of rotation of the type bars G. This frame Q, is hinged at the rear side of the upper part, A, of the framework of the machine, and its circular line of direction is coincident with the circular line of direction of the series of equidistant holes or perforations in and through the stationary horizontal plate or indicator H, placed above said frame, supported in any manner by the upper part of the frame-work, and havingits said holes concentric with the axis of rotation The depression of this circular frame is against a spring suitably applied therefor, and the reaction of this spring returns it to its normal position, the circular frame in both instances swinging upon its hinge, and as it is depressed pressing down upon the imprint-pusher O, and through it upon the typebar under said pusher, as before stated.

I the type of said bar The imprint-pusher O and operating-frame Q therefor may be made in one piece-as, for instance, as shown in Fig. 3 or in separate pieces secured together. To depress the circular frame Q a stylus,R, is provided suitable to be entered into and pressed througha hole, a, of the perforated indicator, and thereby made to press down upon the circular frame Q directly below said hole and the series of such holes of which it makes one. This stylus R is arranged to play vertically within asuitable guidesocket, g, of a horizontal arm, S, loosely hung upon the arbor M, carrying the several type-bars, as has been described, and which arnris'above the perforated indicator, and the depression of this stylus is against a coil-spring, 0', surrounding it and confined end- Wise between a shoulder, t, thereof and the lower end of said guide-socket q; and its return is from the reaction of said spring.

As the circular frame Q extends under and is concentric with the series of holes a of the stationary and perforated indicator H, and said frame is directly above the imprint-pusher O, which directly acts upon a type-bar, as has been above described, it is plain that at what ever hole of the series of holes in the perforated indicator the stylus is entered, it being capable of being brought to any of them by properly swinging the arm S carrying it therefor, it (the stylus) can be made to, and will if so made,press downward upon the circular frame Q, and thus through it secure a'depression of the imprint-pusher O, and through it a depression of the type-bar then directly under said pusher, and consequently an imprint of by the co-operative ac tion of such type and of the ink-ribbon upon the paper about the paper surroundingroller.

In order to secure a determined and known imprint of a type from the entrance of the stylus into a hole of the perforated indicator H, each hole of the indicator is marked in accordance with the type desired to be imprinted upon the paper by the operation of the stylus, as described, and also the types of the typebars are arranged in such relation to each other and to the marking of said holes that when said stylus is entered into any given and marked hole of the perforated indicator the type of the type-bar corresponding therewith will beat the before-referred-to determined and given point of the machinethat is, under the imprint-pusher Oand thus in position to secure, by forcing said stylus through said hole acting upon the swinging frame under it and the imprintpusher directly over said type-bar, an imprint of the type thereof upon the paper, as before stated. This relative arrangement of types and of the marked holes in the perforated indicator is well known in the class of machines to which this invention relates, and, furthermore, the relative position of the type for an imprint thereof, as has been stated, in accordance with the marked hole of the perforated indicator into which the stylus is entered, as has been stated, is insured by the rotation of the type carrier or holder F, through the swinging of the arm S, carrying the stylus, to bring said stylus into position to be entered into the desired hole of the perforated indicator, all as is well known in typewriting machines of the class to which this invention relates.

To adapt the machine described for an imprint, as aforesaid, of letters of the alphabet, both capital and small letters, from a given series of holes in a perforated indicator, of themselves simply covering or equal to one series of the letters of the alphabet (type-bars being provided for the two series of such letters, the one series in capital and the other in small letters) mechanism is provided and shown for rotating the type-bars independently of their rotation by the stylus-carrying arm S, as has been stated. This mechanism, which, for the purpose ofillustrating a complete typewriting machine, is' shown in the drawings, will be now described, bearing in mind that it constitutes no part of this invention, being, as before observed, the invention of Mr. Joseph W. Peck.

The gnechanism consists, in one part, of the horizontal gear-wheel N, hereinbefore referred to as attached to the arbor M of the type-bars G, and in the other part, as the same is shown, of a toothed rack-bar, T, meshing with said gear-wheel at one side thereof and arranged to be slid lengthwise upon a horizontal support, U, therefor, which turns loosely on said arbor. The rack-bar in its aforesaid slide is guided by its guide-slot Y upon headed guidepins a of the support U, and the rack-bar is connected to the arm S, carrying the stylus, and it slides along the length of said arm, being guided by the slot 1) of the arm and its headed pin d, which is entered into said slot. This headed pin 11 holds the rack-bar against accidental escape from the arm S. Sliding the rack-bar on its support U in either direction rotates the type-bars, and this rotation is a rotation separate and independent from the rotation thereof which is secured,as has been de SOl'lbGdfflOm the swinging of the stylus-carrying arm S. Through this separate and independent rotation of the type-bars with a series of types suitably arranged, and embracing both the capital and small letters of the alphabet, either series of said types can be brought into proper relation with the position of the imprint-pusher 0, from the direct depression of which an imprint of a type of a type-bar is produced, as has been described, to secure the imprint of the character of the type desired, and whether the same is to be a capital. or a'small letter, from the insertion and pushing the stylus through a hole of the perforated indicator H, marked correspondingly to said letter, although only one series of so-marked letter-holes are employed in said indicator to two series of type-letters, the one capital and the other small letters of the typebars.

Gonsideredbroadly, the adaptation of a type-writing machine of the class to which this invention pertains to the securing of the imprint of capital and small letters from a series of holes in the perforated indicator, equal in number to only one series of the alphabet-letters, is not new, as is well known, and such being the case and for other obvious reasons, and in viewof what has been stated, it is not deemed necessary to herein more particularly describe the mechanism shown and justabove generally and more or less specifically explained.

The imprint-pusher 0, directly acting on a type-bar, as has been described, has at its upper end a horizontal arm, V, which projects over and across the upper side and at the front of a horizontal and hinged ring, WV, known as a lettenspacing ring--that is, a ring by and from the downward depression of which the carriage of the papersupporting roller is set free for the action of its feeding mechanism to feed said carriage forward for the neXtimprint of a type on the paper carried by the paperroller, or for a space to be left between what has been printed and what is next to beprinted, said ring being returned to its normal position, after having been depressed, by the reaction of a spring suitably'applied, and all as well known, and, as it constitutes no part of this invention, needing no more particular description herein. The depression of this ring also acts to place the actuating mechanism for rotating an ink-ribbon roller, D, in position to turn said roller to feed the ribbon along to pres ent a fresh surface thereof for the nextimprint of a type. This actuating mechanism for an ink ribbon roller, D, is composed of a ratchetwheel,X,at one end of the ribbon-roller, and a pawl, Y, to engage said ratchet-wheel, which pawl is located at the under side of said wheel and projects from the upper side and between the ends of a horizontal lever, Z, one of which ends is free and unconnected and weighted and the other fulcruined by a but ting joint or hinge, f upon the lower end of avertical rod, A which is adjusted to play through a suitable guideway, B, of the upper part of the framework of the machine, and at its upper end is in position for the letter-spacing ring XV, to bear downward thereon when the same is depressed, and thus depress said rod, its said depression being against the action of a spring, 9", surrounding and confined end to end on it, between its shoulder h and a rest or bearing, if, of said frame-work, and said spring, by its reaction on the return movement of said ring WV, returning said rod to its normal position. The depression of this rod A, as aforesaid, carries the pawl Y backward over the teeth of its ratchet-wheel of the ribbon-roller, and on the return of said rod,- as aforesaid, said pawl returning with it, turns the ribbon-roller, and thus the ribbon is fed lengthwise intermittently.

G is a spring-band partially surrounding the upper portion of the edge of one of the heads of the ribbon-roller, and arranged to produce a spring frictional resistance and hold upon the roller against accidental turning as the pawlfor actuating the rolleris being moved back over the teeth of its ratchet-wheel to be placed in position to operate upon said ratchet, to thereby turn the ribbon'roller for the forward feed of the ribbon, as hasbeen described.

Mechanism, such as just above described, is applied at each of the ribbon-rollers, and for placing eithenof the same into and out of operating position and there holding it, according as to which of the ribbonrollers is to be actuated to feed the ribbon and wind the same thereon, unwinding it from the other, a horizontal slidebar, D is provided, of suitable length. This slide-bar D moves through suitable guideways of the upper frame-work, A, and it is provided with a knob, Z'", for operating it, and at each end it has a set-on, m inclining in opposite directions, and each setoff in position to engage with an inclining set on, of, of the weighted end of apawl-carrying lever, Z; and, furthermore, (see Fig. 4, more particularly,) both of said set-offs of the slidebar are in such a position relative to each other and to the set-off of their respective pawl-levers Z that in the slide of said slide-bar in either direction the set-off at one end of said bar, acting upon the setoff of the pawl-lever located at the same end, will lift and hold said pawl-lever out ofits engagement with or operative position in relation to its ratchetwheel of a ribbon-roller. and the set-off at the other end ofsaid bar will be released from the set-off of the pawl-lever located at the same end, and thus said pawl-lever will be set free to fall, to place its pawlinto operative position in relation to its ratchet-wheel of a ribbon roller. By this mechanism the pawl mechanism for the intermittent feed of the ink-ribbon from the one to the other of the ribbon-rollers can be changed, as may be desired.

The paper-supporting roller 13, by the j ournals at its ends, turns in suitable bearings of the carriage O; and at one end this carriage has a set-screw, q entered into it and in position to be made, by properly screwing it, to abut against the end of a rubber cushion, 0", located in the screw-socket into which said set-screw is screwed, and this cushion at its other end is in position-to bear against the end of said end of the carriage, all so as to enable a friction or a resistance of an elastic or yielding character to be put upon said roller against its free rotation under the action of the mechanism to rotate it, and which friction or resistance by properly turning said set-screw may be regulated, as may be desired. By this arrangement the turn of the papersupporting roller may be made more steady and the proper forward feed of the paper, as its roller is turned, is thereby insured, and accidental slips or uneven feeding of the paper rendered impossible, however careless the operator may be in the handling of the mechanism of the machine for feeding the pa per.

In type-writing machines, as well known, an alarm-bell, E is used for signaling the approach by the machine of the printing to the end of the length of the line desired. This signaling is secured from the movement of the carriage carrying the paper-supportmg roller in the direction lengthwise of said roller. In this invention, for this purpose, the carriage for the papersupporting roller is provided with a dog, F capable of attach ment to and detachment from said carriage at pleasure, and of being located at various points along its length. This dog F is hung at its upper end by a pivot, t, to the upper end of a standard or post, G, which at its lower end has dowel-pins a that are entered into corresponding shaped sockets suitably located therefor, and arranged along the upper side of a horizontal bar, H, of the paper-supporting roller-carriage O. The lower end of this dog F is free, but rests on the upper edge of said bar, and the dog is in line with an arm, b of the swinging hammer d" of the bell, and as the carriage travels ,to carry the paper-supporting roller and the paper thereon to the end of the length of line desired to be printed it passes into contact with and under said arm ofthebell-hammer, liltingthesame, and finally passing out of such contact and therefrom it leaves the hammer free to fall, and thus the sounding of thebell is caused. This sounding of the bell bya proper adjustment of said dog on the bar, preferably, is made to occur just a few letters before the end of the line which is being printed is reached. On the return of the carriage and its paper-supporting roller for another line to be printed, as before, the dog, in passing by the arm 22 of the bell-hammer, lifts from its contact therewith, and no movement of either said arm or of the bell-hammeris produced.

As has been particularly shown and de scribed, the separate and independent typebars are arranged in a circle, which is most preferable; but they may be arranged in a straight line, as shown in Fig. 11, in three separate views, a face in two sections on lines at right angles. The mechanism for the intermittent' lengthwise feed of the ink-ribbon and for changing the direction of such feed, for producing frictional resistance to the rotation of the paper-supporting roller, and for sounding the alarm-bell, all as herein described, obviously each and all may be applied to type-writing machines of other classes than that herein particularly described. The independent and separate acting type-bars may be rigid in themselves, and being hinged or otherwise suitably attached to their holder, then rendered flexible or elastic by means of springs applied to each separately, (see Fig.12;) but it is preferable to make them, in themselves, flexible or elastic.

I make no claim in this case to any feature of invention shown and described in an application filed by me the 28th day of September, 1886, Serial No. 214,759, for improvements in type-writing machines.

Havingthus described my invention, I claim and desire to secure by Letters Patent- 1.
