SPECIFICATION forming part of Letters Patent No. 352,160, dated NovemberQ, 1886.

Application filed rbrunry`17,1ss5. serial No. 156,156. (No model.)

To all whoml it may concern:

Be it knownthat I, CHARLEs SrIRo, of New York city, New York, have invented certain new and useful Improvements in Type-friting Machines, of which the following is a speci-` iication. f

My invention relates to that class of typewriters having a rotary type-wheel and atwirling-handle which is revolved to bring the desired type to the printing-point, and in which a reciprocating motion of the type wheel or carriage to or from each other effects theprinting of the selected letter. s

The chief aim of my present invention is to provide a type-writer with two or more distinct type-wheels, one wheel having, say, the small letters, and the other wheel or.wheels having capitals or other characters, either wheel being capable of being thrown into action when desired, sozthat more perfect and elaborate printing maybe thus accomplished.

In'two former applications, Nos. 126, 354 and 144,014, filed by me April 1, 1884, and September 26, 1884, the paper-carriage slides in a stationary bed, and thetype-wheel is mounted withlits axis horizontal on a depressible lever above the carriage, so that the typewheel has both a rotary and reciprocating movement, it being rotated to select the desired letter and depressed against the paper-roller on the carriage toprint the same.

N ow,in my presentinvention the axis of the type wheeler wheels is stationary, and is preferably disposed in a vertical position,while the paper-carriage moves m,in a rocking or reciproeating bed, which is moved to and from the type-wheels to effect the printing action. The type-wheels are capable of being slid or shifted on their axis, and a manipulating-key is provided for thus shifting either wheel into action. A twirling-handle is also employed for operating the rotary type-wheels and the reciprocating carriage, said handle having a rotative engagement with the type-wheels anda reciprocative engagement with the carriage, or, rather, the rocking bed of the carriage, so that by twirling the handle the wheels maybe rotated to bring kthe desired letter to the printing position, and by depressing said handle the carriage will be tilted against the wheel to print the said letter. p

My present improvement therefore consists I l partlyin the `features above outlined and partly B' and their adjuncts.

in the feeding mechanism employed for feeding the carriage step -by step after the print- 55 ing of each successive letter. This feeding mechanism is constructed on the same principle as that shown in my former applications--v that is, it employs a reciprocating feed-pawl.

which engages-a rack on the carriage, and is 5o operated by the reciprocating movements of the printing device,and the length of the feeding strokes of the'pawl islimited to correspond to the width ofthe letter printed by means of stops of variable length on the type-wheel cor 65 responding to the variable widths of the types thereon. The special construction and arrangement of the feeding mechanism is, however, novel, to adapt it to the novel form of my present machine, as is hereinafter shown. 7o My invention also embodies some improvements in the inking device, in the spacing-key device, in the dial or index, and in other details, as hereinafter fully set forth.

In the drawings annexed, Figure 1 presents 75 a front elevation of ny improved type-writer, shown in section inthe region of the typewheels and their operating mechanism. Fig.

2 is a plan view,with the stationary axis of the type-wheels in section and the type-wheels 8c removed. Fig. 3 is a view similar to Fig. 2, but with the paper-carriage also removed, to better show the feed mechanisms. Fig. an end elevation with the parts in normal position, and Fig. 5 is a similar view with the 85 twirling-handle depressed and the carriage tilted up against the type-wheel to print the selected letter. Fig. G is a cross-section on line x x of Fig. 2. Fig. 7 is a detail of the spacing-key and the feed devices. Fig. 8 is 9o a plan view of the index-dial of the machine. Fig. 9 is a plan view like Fig. 3, showing the position of parts when the spacing-key is depressedfor the spacingfeed. Figs. 10, 1,1, and 12 give detail views ofthe type-wheels and the 95 preferred form of inking mechanism.-

Referring to Figs. 1, 2, 3, and 4, a indicates the bed or table of the machine, which is supported on a number of short'legs or feet, b, as seen best in Figs. 1 and 4. Along one side of roo the base is disposed the paper-carriage A, and on the opposite side of the base and at the center. thereof are mounted the type-wheels B At one side ofthe type-wheels the twirling or operating handle 105 G arises from the base, and at the opposite side projects the shifting-key E, for shifting the type-wheels, and the spacing-key D, for producing the independent spacing-feed. The side of the base beneath the carriage A is perforated with a long open slot or panel, c, above which is mounted a rocking frame or cradle, F, having dovetailed ways, in which the dovetailed base of the carriage is fitted, and is free to slide therein back and forth past the type-wheels, as will be readily understood from Figs. 2, 3, 4, and 6. The rocking bed or cradle F is mounted at each end on pendent arms f f, which are pivoted to posts g g below the base at each end of the open panel c, so that the cradle, with its carriage, is thus capable of rocking to and from the type-wheels to produce the printing action, as will be readily understood from Figs. 4 and 6, where the carriage and cradle are shown tilted away from the type-wheels, and from Fig. 5, where the carriage is shown tilted toward the type-wheel to receive the imprint of the selected letter.

The paper-carriage is composed of the usual parts shown in my former applications-viz., the dovetailed base or frame p, the paperroller r, mounted thereon, the ratchet-rack t, which extends along the front edge of the base, the springs 3 3, pressing under the roller to support the paper thereagainst, and the similar springs 5 5, pressing against the top of the roller, to still further support and guide the paper, which latter springs are a new fea` ture in this machine, and project from a bar, 6, extending over the top of the roller.

The type-wheels B B', as shown best in Figs. 1 and 6, are preferably two, although more may be used, and they are disposed, as shown, in horizontal planes, one above the other, on a vertical axis. The type-wheels are simple metal disks, in the slotted peripheries of which metal types are soldered, and each wheel contains a distinct series or style of type-that is, the upper wheel, B, which is the one most used, contains the small letters and points of punctuation, while the lower wheel, B', contains the capital letters and numerals, as shown by the index-dial in Fig. 8.

Referring now to Fig. l, h indicates the axis or shaft of the type-wheels, which is j ournaled at the lower end in the base a and at the upper end in a cross-bar, 1'-, which extends between two framing-posts, k 7i, which arise from the base on each side of the wheels, and which, together with a circular shield, k', extending from post to post, inclose and protect the wheels, as best shown in Figs. 2, 4, 5, and 6.

The type-wheels B B, as best seen in Figs. l and 6, are not mounted directly on the shaft or axis h, but on a sliding hub, l, which slides on said shaft. rlhe hub and wheels are, however, engaged with the shaft by a pin, m, which projects from a collar, m', fixed to the shaft, and passes down through holes in the t-ypewheels and hub, thus engaging the hub and wheels rotatively with the shaft, and yet allowing the hub and wheels to be slid up and down thereon, so as to shift either wheel into action.

Now, the twirling-handle C, as shown best in Fig. l, is disposed verticallyin a plane parallel with the axis of the type-wheels, and the spindle c of the handle passes down through a fixed guiding-sleeve, and projects below the base, where it is secured to a gear-wheel, iz, which gears with a similar wheel, 0, affixed to the lower end of the type-wheel shaft 71, so that the twirling-handle has thus a rotative engagement with the ty pe-wheels, whereby the same may be easily turned to bring the desired letter to the printing-point. A dial, 8, containing the differentcharacters on the type-wheels, as shown in Fig. 8, is fixed above the typewhcels to the cross-bar t', as seen in Figs. l, 4, 5, and 6, and an index-finger, l0, attached to the shaft ofthe wheels, projects over said dial and shows when the desired letter is brought to the printing-point, as will be understood.

Now, the twirling-handle G is not only free to revolve to turn the type-wheels, but is also free to reciprocate up and down, and is counectcd in this direction with the carriage, so as to move the same to or from the type-wheels to effect the printing of the selected letter. For this purpose the lower end of the shaft of the handle C rests on the extremity of an elbow arm or lever, s, which projects rigidly from the rocking base or cradle F of the carriage, as best shown in Figs. 4, 5, and l, hence when the handle C is revolved or twirled between the fingers in one direction or the other, as indicated in Fig. 1, the typewheels will be revolved to bring the desired letter to the printing position, and if the handle is now depressed the carriage willbe tilted toward the type-wheels, as seen in Fig. 5, and the paper-roller thus forced against the selected type to print the same upon the sheet of paper 12 on the roller, as seen in Fig. 5. V'Vhen the depressed handle is now allowed to rise, the carriage will be retracted or tilted from the type-wheels into its normal position (shown in Figs. 4 and 6) by a spring, u, one end of which is affixed to the inner edge of the cradle and the other end to an adjustable slide, u', on the fixed base a, so that by adjusting a screw, u2, affixed to said slide the tension of the retracting-spring may be adjusted as required.

Referring to Fig. l, it will be seen that the teeth of the gear-wheels a ovare sufficiently wide to allow the reciprocating movements of the handle C and its wheel n without carrying the wheels out of mesh.

Now, referring to Figs. l and 4, it will be seen that the upper type-wheel, B, which is the one almost constantly used, as it carries the small letters and punctuation-marks, remains normally in the printing position, as shown. The upper wheel, B, remains normally in this position, for the reason that both wheels,with their hub l, normally gravitate toward the base where the end of the hub rests 011 the forked end of the key-lever E, leaving the upper wheel, B, on a level with the middle of the paper-roller of the carriage, which is of course the printing plane or line of the machine, as



n shown best in Figs.A 1 and 4; hence, when the twirling-handle is operated without touching the key E, the upper wheel, B, will always be "of small letters, as before.

printed from, and the lower or capital wheel, B', will remain out of action below the printiing-line of the machine, as shown in Figs. l

and 4. If, however, the knob of the lever E `is depressed, then the hub Zand its wheels B 4 mechanisms much more elaborateand perfect i forth in my former applications.

ing the spacing-key D an independent feed` printing can be accomplished, and greater beauty and variety may be given to the writing. Thus by touching the keyE at anytime that a capital is required to commence a word or-sentence, or when it is desired to print a word all in capitals, these capitals will be accurately and neatly printed in proper place to contrast with the smaller letters printed from the wheel B, and this variety in the printing will be accomplished without anyloss of time, for it will be seen that one hand will operate the handle C, while the other is free to operate the key E, and the movements y of one will in no way interfere with those of the other, thus accomplishing amost desirable improvement in typewriters. Now, everytime the handle C is reciprocatedup and down to effect the rocking of the carriage and the printing of the letter a feed movement will be impartedto'thecarriage to advance it steppby step for each successive letter, and these feedsteps will vary in length corresponding to the width of the letter printed, thus producing a regulated feed spacing on the principle set By depressmovement will be imparted to the carriage to provide space between words or sentences, which space may be increased, as desired, by depressing the key two or more times, as is usual in type-writers.

Now, theautoniatic feeding mechanismabove referredto is of such a nature as is difficult to simply illustrate and describe, and requires close attention for its elucidation, which will be now proceeded with. g l Referring first to Fig. 3, o indicates the feedpawl, which engages the rack t on the carriage. This pawlfis pivoted at its middle on the pawl-lever fw, which is in turn pivoted under the back edge of `the cradle F, as well shown in Fig. 3, and hence rocks with the cradle. On the fulcrum-pivotrf the pawl-lever fw is also pivoted an elbow-lever, y, one arm of which bears uponY a fixed pin, x, in the base a, and is constantly held against said pin by a spring, gf, the end vof which is connected to the opposite edge of the cradle, as shown in Figs. 3, 4, 5, and 6; The opposite arm' of the elbow-lever y lies under the pawl-lever w and carries a spring-tongue, y', while a pin, w', projects from the elbow-lever w, and is embraced between the tongue g/ and the elbow-lever J. It will therefore be seen that the elbow-lever and pawl-lever are engaged 'together by an engagement which is rigid in one direction and yieldingin the other-that is, rigid in the direction in which the arm of the elbow-lever bears against the pin w, and yielding where the spring `i/"bears against the pin. It will now be seen that when the cradle is rocked to tilt the carriage toward the type-wheels to print the letter the pawl-lever w will rock with the cradle, and by reason of the engagement of the elbow-lever y, which bears on the fixed base-pin the pawl-leverw will be caused to move in an arc tangentto the rack t, andwill hence slip the pawl@ back over the raekteeth, as indicated in Fig. 3. Now, in this direction of motion the engagement of the twolevers w y is yielding by reason ot' the spring y bearing on the pin lw', but if the pawl-lever meets with no obstruction in this back movement there will be no yield, as the lever and pawl will be moved back the full distance, and the spring y will not be flexed` so that the pawl will therefore slip back over four or more teeth on the rack, or sufficient to produce a full'feed movement equalto the widest letter on the type-wheel. rocks up and tilts the'carriage away from the type-wheels, the levers w y will swing forward, the pawl v will engage the teeth of the rack, andthe engagement of the two levers being rigid in this direction, as described, a positive forward feed movement will be imparted to the carriage equal to thc distance which the pawl slipped over at the first or back motion. lf, however, during the back motion of the pawl and levers,the lever w were obstructed or stopped after t-he pawl `had slipped over one, two, or three teeth, then the spring `y would tleX, to allow`the elbow-lever y to make the remainder of its sway idly, as shown in Fig. 3, while the pawl and lever v w remained stationary at the point at which they were obstructed. Therefore, on the return or forward stroke of the parts, the elbow-lever y would Now, when the cradle,



first take up the idle play between itself and as will be understood. Now, the obstruction ofv the back motion of the pawl-lever is determined by a stoplever, e, (shown best in Figs. l and 7,)whose positionsare in turn-deter mined by 'variable stops on the type-wheel corresponding to the variable widths of the `f Y types thereon on the principle shown in my former applications. This stop-lever is piv stretched, as shown in Fig. 9.

oted ou one of the posts k, and one of its arms projects down toward the base, while the other arm projects up toward the type-wheels, and is provided with an adjusting-somme', the tip of which is on a level with the rim of the active type-wheel, and is adapted to enter recesses or spaces between the types. A pin or projection, 15, extends from the pawllever toward the lower arm of the stop-lever z, and the two are also connected by the spring z2, so that hence every time the pawllever is moved backward it will sway the stop-lever e and cause the screw e on its tip to enter one of the recesses between the j types on the rim of the type-wheel, as best seen Now, these recesses vary in depth.

in Fig. 9. see Fig. 9) according to the variable width of the types, as shown in my former application; hence it will be seen that every time the pawllever i@ is moved back it will be obstructed sooner or later in its stroke by the action of the stop-lever a encountering a recess corresponding to the letter printed, so that the feed pawl will thus take in a varying number of teeth, and at the next forward movement will feed the carriage forward this number of teeth to correspond to the width of this letter, there` by providing an automaticallyregulated spacing in the printing ol' the letters, as will be readily understood from the description and illustration given.

Referring to Figs. 1 and 2, it may be seen that the pawl-lever io also carries 'a long rigid detent-tooth, 16, which. when the lever has swung fully forward, will engage one of the rack-teeth and hold the carriage rmly from movement in either direction by momentum or otherwise. This detent-tooth is of course always withdrawn as soon as the lever moves back, as seen in Fig. 3.

To produce the independent spacingfeed, the key D is depressed, as before described, and this key, being operatively connected with the pawl-lever, as shown best in Figs. 2 and 7, will operate the feeding mechanism to produce the desired movement.

Referring to Fig. 7, it will be seen that the key-lever D has a projection, 17, which bears upon the end ofthe pawl-leverw and carries at its extremity an upwardly-projecting hook or cam, 18, which approaches the tail of the pawl o, as shown Well in Figs. 2, 6, and 7. Vhen, therefore, the key D is depressed, as seen in Fig. 7, the pawl-lever will be moved back and the pawl will slip over the teeth, and as in this direction the piu w' will be forced against the leveri, (see Figs. 2 and 9,) the outer arm of the lever y will be moved away from the stoppin m, and the spring y2 will therefore be Vhen, therefore, the key D is released, the spring i 2, reacting,will movethepawl-lever and pawl forward, and thus feed the carriage forward the full space of one feed-stroke, thus giving the desired feed.

When the key D is fully depressed, as shown in Figs. 7 and 6, the hook 18 will be forced against the tail of the pawl o, as shown in Fig. G, thus withdrawing the pawl from the rack, and enabling the carriage to be freely shifted back or forth to any desired position in its guides. When the key is released, the pawl engages the rack as before, as will be readily com p reh ended.

Referring to Figs. 2 and 3, I prefer to make the gear-wheels a o with a number of teeth equal to the number of characters on the typewheels, and I arrange a spring click-lever, 19, to engage the periphery of the gearwvheci o, so that the pointoi' the click-lever, falling between the teeth of the gearewheel, will assist the hand in turning the type-wheel to the desired letter, and prevent the wheel from easily shifting when the letter is brought to the printingpoint. When, however, the handle is depressed to print the letter, the click-lever is rigidly held against the wheel, which is thus locked to prevent the motion of the type-wheel during the printing action. This locking action is accomplished as follows: The level' 19 is pivoted to the base a, beneath the same, and to it is attached a spring, 20, which bears upon the edge of the base, as shown by :full and dotted lines in Figs. 2 and 3, and thus tends to keep the point of the lever constantly pressed into engagement with the teeth of the wheel. To the lever 19 is also attached a rigid arm, 21, carrying at its tip a set-screw, 22, which projects toward the edge ofthe carriage-cradle, as shown in Figs. 2 and 3. New, when the cradle is rocked up and the carriage tilted away from the type-wheels, as shown in Fig. 2, the spring 20 will still press the iever 19 against the gear-wheel o, and will also yield to allow the lever to click over the teeth as the gear-wheel is revolved, as indicated by dotted lines in Fig. 2. As soon, however, as the desired letter is brought to the printingpoint, the click-lever will spring into engagement with the appropriate tooth to hold the wheel, and as soon as the carriage is now tilted toward the type-wheels to print this letter the edge of the carriage-cradle will be brought rigidly against the tip of the screw 22, as shown in Fig. 3, and will thus rigidly lock the clicklever 19 against the wheel o, thereby locking the type-wheels against rotation while the letter is being printed. When the carriage is tilted against the type-wheel to print, as before described, the front edge of the carriagecradle strikes against a stop, 23, on the base, (see Figs. l, 2, 3, and 4,) whichlimits the imprinting inotion of the carriage. This stop 23 is an eccentric rotary pin rotating in a socket in the base, and provided with a handle, 24, as shown, so that by turning this stoppin more or less one way or the other the iinprinting movement of the carriage may be more or less limited, and the impression of the types thus regulated, as may be desired.

The inking mechanism which I employ is on the principle shown in my former application, but modified to suit the present arrangements, and is best seen in Figs. l, 2, 3, and et.v



its innerl end a hub or sleeve, which encircles the hub Z of the type-wheels, and is free to partly revolve or oscillate thereon about the aXis of the wheels. At the outer end this oscillating arm carries two small verticalrollers, 25, over which passes an endless inking-band, 26, which runs against the typed rim of the type-wheels, as best shown in Figs. 4,2, and 3, and hence as the wheels are revolved against the band'the bandwill also revolve against the wheel, and thus properly ink the types. In order to make the inking more e'ective, an oscillating motion is imparted to the inkerarm at each reciprocation of the carriage by means of a lever, j, pivoted on the stud 7c3, one arm of which engages with a crank-pin, 27, on the hub ofthe inker-'arrn, while the other arm of the lever bears upon the edge ofthe carriage-cradle, as shown in Figs. 2, 3, and 4.

A retracting-spring, 28, connected at one end with the lever j and attached at the opposite end to the carriage-cradle, tends constantly to keep the lever pressed against the edge of the retracted cradle, as seen in Fig. 2, and to swing the inker around into its normal position,where the inkingbandis before the printing-point, so as to be sure to ink the letter which is selected before the imprinting motion takes place. As soon, however, as the imprinting motion takes place by the rocking forward of the cradle and the tilting of the carriage toward `the typewheels,the movement of the edge of the cradle against the lever j causes said lever to be swayed,and

to consequently swing the inker partly around the wheels away from 'the printing-point, as shown in Fig. "3, thus removing the inker from in front of the selected letter after the same has been effectuallyinked,thus enabling the carriage to come up to the wheel to take the impression of the inked letter, as will be readily understood.- Vhen the carriage is again tilted away'from the type-wheels, the

inker is automatically swung back into its normal position, as shown in Fig. 2, thereby insuring by said movements a perfect inking of the types.

In lieu of the inking mechanism just described I greatly prefer to employ that shown in Figs. 10, 11, and 12, as this is more perfect,V

in actionV and more convenient to manage. Fig. 10 shows a plan view of the type-wheel and the inking device. Fig. 11 gives an end elevation with the inker at the printing-point of the wheels and the wheels partly raised up out of their normal position. Fig. 12 is a similar view, with the wheels fully raised to bring the lower or capital wheelinto action. In kthis mechanism the inker does not niove up and down with the wheels when the same are shifted, as the inker-arm q is mounted on a fixed bracket or cross-bar, 40, which extends crosswise'beneath the wheels, and is fixed to the posts k k. This bracket 'has a central opening, through which the hubs of the typewheels pass, and the inker-arm q has asimilar central opening to loosely encircle the J hub, as shown Well in Figs. 10, 11and 12. TheLinker-arm g is held on the bracket 41 by two screws, 47, which pass through curved slots in the arm, and thus permit the arm to vibrate or oscillate around the axis of the type-wheels. The inkerarm is providedwith the crank-pin 27, as'before described, and is engaged with the lever j, so that everytime the carriage is reciprocated the arm is vibrated with lthe same effect as already described. Now, instead of the inking band and rollers before described, I mount on the end of the arm q a single ink-disk oriat roller, 42, which revolves flatwise against the type-wheel. This disk 42 is pivoted on a short arm, 43, which is hinged or jointed to the end of the inkerarm, and the hinged end is pressed upon by a spring, 44, in the manner of a knife-blade, thereby tending constantly to force the ink- Adisk toward the rim of the wheels in an inclined position, so that the upper edge of the disk presses against the active type-wheel and is free to revolve against the same to ink the types effectually, while the lower part of the disk is outv of contact with both wheels, thus applying the ink only to the wheel which is in action. Now, when it is desired to replenlish the ink on the disk, it is only necessary to swing or press the disk backward on its hinge AIoo iently applied thereto, after which the disk is l swung back in its place, and the spring 44 will hold it against the wheel, as shown in Figs. 11' and 12. The inking-disk is preferably made of an outer disk of metal covered with an inner disk of felt to hold the ink and contact with the types. As before stated, this inking device always remains at the same level, and does not move up or down when the type-wheels are shifted, but always bears on the wheel which is in action, as fully illustrated in Figs. 11 and l12. In order, however, to prevent the rim of the Wheelsfroln Wedging or catching in the inclined face of the disk when the wheels are shifted up or down, the sliding hub of the wheels is arranged to actuate a lever to press the disk slightly away from the wheels during the shifting motion, and allow it to come back when the Wheels come into position. complish this action, the hub of the wheels is made with a spherical bulge, 48, as seen best in Figs. 11 and 12, and on the arm q is pivoted a To ac- IIO small lever, 45, the short arm of which projects against the bulge, while thelong arm -extends toward the ink-disk, and is terminated with a wedging or inclined tip, which engages a corresponding incline or wedge, 46, on the hinged arm 43 of the disk. It may now be seen that when the hub Z is slid up to shift the upper wheel out of and the lower wheel into action, as seen in Fig. 11, the bulge 48 will press against the lever 45 and sway its Wedging end against the wed ging face on the hinged arm 43,

and thus press t-he disk slightly outward away from the wheels and permit them to shift without scratching or catching in the disk. Vhen the wheels are fully shifted up, as seen in Fig. l2, the bulge will have passed above the lever 45, and will thereby allow the disk to spring back in its place against the wheel. It will be readily seen that the same action will take place when the wheels are shifted down into their normal position to bring the upper wheel to the printing position, in which case the disk 42 will be swung slightly outward to prevent the upper wheel from catching against its edge, and after the bulge 4S passes below the lever 45 the disk will again spring back in proper contact with the rim of the wheel, as will be readily understood from the deseri ption and illustration already given.

I prefer to arrange the letters on the type- Wheels in the order shown in Fig. S, or similar to the arrangement of typein a printer-s case. This brings the letters most used within a short are on the dial and enables much more rapid work to be accomplished, as no unnecessary time is wasted in needlessly wide movements to reach and select the letter.

I lay no claim, broadly, to the combination of a movable paper-carriage with a rocking frame in which the same slides, and a rotary and reciprocating handle geared with the typewheel.

What I claim isl. The combination, with the reciprocating paper-carriage and the rotary type-wheel having stops of varying length corresponding to the width ofthe letters, of the feed devices consisting of the levers g/ w, spring y', stop w, and pawl o, stop x', and spring y, with a rack on the carriage and an interposed obstructive connection between the pawl-lever and the stops on the type-wheel, arranged and operating substantially as set fort-h.

2. The combination, with the reciprocating carriage having a 1'eedrack,ot` the feed devices consisting of the iin ger-key E, pawl-lever w, pawl c, elbow-lever y, spring y', stop w', with the stop x and spring y?, arranged and operating substantially as and for the purpose set forth.

3. In a type-writer, the combination, with the paper-carriage and its rack, of the spacingkey lever E, pawl-lever w, pawl c, and the hook or stop 1S on the lever E, to withdraw the pawl, substantially as and for the purpose set forth.

4. The combination, with the type wheel having variable stops, and the sliding feedcarriage having a ratchet-rack, of the feed devices consisting of the levers w y, connected as described, the pawl @,with the stop-lever z, operated by the pawl-lever, and its pin z', arranged to encounter the stops on the typewheel, substantially as shown and described.

5.
