' SPECIFICATION forming part of Letters Patent Nor-$549,523, dated November 12, 1895.

Application led July 3, 1885.` Serial No. 170,645. (No model.)

To all whom t may concern: f

'Be tknown that I, CHARLES T. MOORE,

of I/Vashington, in the District of Columbia, have invented certain new and useful Im-r 'provements in Methods of Printing and in Type-Writing Machines; and I do hereby declare the followingV to be a full, clear, and exact description of the same, reference being .had to the accompanying drawings, formingl 1o a part of this specification, and to the figures and letters of reference marked thereon.

My invention relates to a method of printing, which consists in taking a blank sheet,

the previously-selected character, and bringing the last character into juxtaposition with said sheet'and moving the 'sheet laterally as 2o the characters are selected and printed, and moving it longitudinally when a line has been printed, and to a method involving the selection of a character to be printed bringing said character into printing position, gaging 2 5 'the distance for feeding the paper corresponding to the width of the character brought to position, selecting the same or another character, printing the character previously selected, bringing the last character into juxtaposition with the sheet, executing the feed previously gaged, and gaging the length of of feed corresponding to the width of s aid last-designated character, and so' on, to form words.

3 5 Theinvention also relates to mechanism hereinafter described by whichtheforegoing processes or methods y may be conveniently practiced, and to that class of typewriting machines in which a rotatable typewheel having on its face or periphery letters or characters from which to print is adapted to be arrested at the printing-point by the engagement with an arm upon its shaft of a pin projected from the face of a dial by the operation of a finger-key corresponding to the character desired'to be printed. fore inall machines of this class, so far as I am advised, thetype-wheel has been so arranged with respect to the keyboard as that 5o when a key was pressed bythe operatorv the type-wheel was caused to rotate so as to Heretobring the character corresponding to the key to the printing-point and there make an impression, vthe whole operation being completed by the time the key depressed resumed 5 5 its normal position, which it. did upon the pressure of the finger being removed from it.

Y In my present machine, in order to carry out my new method of printing, Ihave introduced what I believe to be a new principle of opera- 6o tion, which is this: Instead of printing the character designated by the key depressed, as is usually the case, I print by the depression of suchkey the character designated by the depression 'of the last previous key operated 65 upon and set the machine so that it will print in turn said last-designated character upon the designation of the one next succeeding it, by which I am enabled to secure greater uniformity in the' printing and a higherrate of 7o speed. I also so arrange my paper-feeding devices as to cause an advance of the paper proportioned to the width of the characters printed, and I preferably provide suitable contrivances for applyingordinary printing- 7 5 ink to the type-wheel, thereby securing print which cannot be distinguished from that or dinarilyv produced by the printer with the usual aplliances.v

There are many other important principles 8o .involved in my machine which I will not at this point consider, deeming it more advisable to first describe the machine and its operation at length and then point out its several features of novelty in the claims at the close of this specification.

Referring to the accompanying drawings, Figure l is a plan view of the machine with the covering of the inking apparatus removed to show the ink distributing and applying 9o rollers and with a portion of the bed broken ,p away to show the devices for operating the distributing-roller.

Similar letters and figures of reference in the several iigures indicate the same parts.

S represents the type-wheel shaft arranged vertically of the machine and supported in suitable bearings therein. Upon this shaft are loosely mounted two type-wheels E E2, the same being connected by a common hub or sleeve A and prevented from independent rotation by rods d2, passing through them and secured to heads or collars d2 d2, fixed to the shaft, as shown in Fig. 2. These type-wheels E E2 are provided on their pcripheries with upper and lower case characters, respectively. The upper portion of the type-wheel shaft is made hollow to receive a rod or shaft I, and is slotted at S to permit of the movement of a yoke F, which passes through the said shaft I and is secured at opposite ends to the upper type-wheel E2. Connected to the shaft I at F is the bent end L2 of a vertical rod L/, which is guided at F5, A2, and T2, as shown in Fig. 2. Near the lower end this rod L is provided with a pin T4 and upon it below this pin is mounted a sleeve T, to which is connected one arm of a toggle T T2, the other arm of said toggle being connected to the step or bearing T2. A rod L connects the toggle T T2 to a frame B2, that extends from side to side of the machine beneath the keyboard and is capable of a slight lateral motion in guides H2112, though it is normally kept pressed backward by means of springs l-l' li. The lower arm of bell-crank levers B, pivoted to the frame of the machine, is provided with a slot in which projects a pin on the frame B2, while the upper arm of said levers has bearing upon it a bar B, extending from side to side of the machine and secured to arms BX, pivoted at l0, as shown in Fig. 2. A

The frame B2 is provided with two series of spring-pins 192133, the former or forward series p2 occupying normally a position immediately beneath pins p, projecting from the under side of the keys K of the keyboard. lVhen the pins p2 are thus beneath the pins p, the frame B2 is held pressed, back to the limit of its movement by the springs ll and the connecting-rod L, the toggle T T2, the sleeve T, rod L', shaft F, and the type-wheels carried by the latter occupying the position shown in Fig. 2, the upper type-wheel (which is the one on which the lower-case characters are arranged) standing opposite the presserbar P of the paper-carriage and remaining there so long as the lower-ease characters are desired to be printed. lVhen, however, it is desired to print upper-case characters, the bar B in front of the keyboard is pressed, thereby causing the bell-crank levers B/ to move forward the pin-frame B2 and bring the series of pins p beneath the pins p, causing the connecting-bar L to straighten out the togglearms T T2 and thereby through the sleeve T' and pin Tl elevate the rod L/, and thus, vthrough the intermediate connections before described, raise the type-wheel E, bearing the upper-case characters to the printing-point opposite the presser-bar P.

Each time the rod L is lifted, so as to bring the lower type-wheel bearing the upper-case characters in position for printing, a pin 'i upon said rod strikes and passes one arm of a pivoted bell-crank lever 71., projecting in its path, after which said lever is returned to its first position by means of a spring 7L* and serves by supporting the said pin i to maintain said type-wheel in its adjusted position, where it remains until ithe next key is presssed, when said bell-crank lever 7L is thrown out of engagement with the pin fz' by the action of a pin-wheel L, co-operatin g with its lower arm, and a rod g, bearing a pawl and actin g upon a ratchet secured to said pin-wheel and itself actuated by a lever F/, attached to a bar F, extending from side to side of the machine bcneath the finger-keys, as shown in Fig. 2.

The means for shifting and holding the type-wheels having now been described the means for imparting rotary movement to the type-wheel shaft and the type-wheels thereon and the devices for effecting the starting and stopping of the same, pursuant to the movements of the finger-keys, will be next considered. Mounted in iixed bearings Al A5 and with the type -wheel shaft passing loosely through it is a barrel b2, containing a helical spring, which is secured at its inner end to the type-wheel shaft and at its outer end to said barrel b2. A pinion nf, formed upon or secured to said barrel b2, meshes with a larger gear-wheel lV, fixed to a shaft S3. This shaft S2 has a barrel b loosely mounted upon it,

containing a helical spring stronger than the mounted upon a fixed sleeve S2, through rIOl which the shaft Ss passes, is Ystill another barrel b, containing a spring having its outer end secured to said barrel b and its inner end to said Xed sleeve S2. Connection is made between the barrels Z9 b by means of a ratchet 5X, formed upon the upper portion of the barrel b, and a pawl bXX, mounted upon the barrel b and engaging said ratchet, as shown in Figs. 2 and 16, and connection is made between the barrel b and a reciprocating papercarriage N by means of a rack-bar R, secured by arms R to said carriage, (see Figs. 2 and 4,) and a pinion n, formed upon said barrel b and meshing into said rack-bar.

Each time the reciprocating paper-carriage is brought back to starting-point after having completed the'movement in front of the type-wheel (which may be done by hand or by a foot-lever operating through a cord or chain C5, Fig. 3).the rack R, connected to it, operating through the pinion n, winds up the spring within the barrel Z) and the said barrel l), operating in turn through the pawl-and- -ratchet connection bXX 19X before referred to,`

causes the spring within the barrel b to be also Wound up andto operate through shaft S2, wheel lV, and pinion at to turn the barrel b2 and wind up Vthe spring contained within it that acts directly upon the type -wheel shaft S. From this arrangement it will be seen that the type-wheel shaft and the typewheels thereon are propelled by the spring in barrel b2, which spring'` is kept constantly woundb y the action of the spring in the barrel b', and, further, that the last-named spring andthe spring in the barrel b are, by reason of the pawl-and-ratchet connection between their respective barrels, wound up simultaneouslywhenever the paper-carriage is brought back to starting-point by the action ofthe operators hand or foot, though in unwinding they, are entirely independent in their operai' tion and perform their separate functions without interference.

lt will be understood that by reason of the series of springs b2, b', and b, arranged and operating as described, the type-wheels will be given their impulse and be caused to revolve by the action of the spring h2, which is applied directly to the type-Wheel shaft. The movement of the type-wheels, therefore, is more prompt and uniform than would'be the caseV were the power applied indirectly through the medium of a fusee. Another advantage is that the light spring applied directly to the shaft does not acquire such momentum as would be the case with a train of gearing, and therefore shocks and strains from such source are avoided.`

It will of .course be understood that the spring in b is relied upon to feed the papercarriage forward whenever a stop in front of said carriage is released.

The lower endof the type-wheel shaft passes centrally into and has a bearing in a circular dialV D. This dial has arranged around it a series of pins e, as many in num-I in Figs. 9 and l0.

ber as there are keys ,to the keyboardV and characters upon either of the type-wheels. Each of these pins is provided with a slot EX in its outer edge, into which projects a shoulder eXX from the body ofthe dial, the object of which construction is to enable the pin to have a limited sliding lmotion vertically. Each pin is further provided with a beveled upper end and with a shoulder e2, as shown of the pins of the dial is arranged the bent end k of a lever K2, pivoted at 3 to a suitable fulcrum or support upon a fixed cross-bar A2. These levers K2 are arranged in the manner shown in Fig. 5, and each one is adapted to be actuated from one of the keys K of the keyboard by means of a pin p, as shown in Fig. 2. When any one of the keys K is depressed, lthe pin p depresses one end of the lever K2 beneath it and throws up the other bent end 7c of said lever and causesit to force upward the appropriate dial-pin above it, as shown in Fig. 2, while upon pressure being removed from the key the lever K2 will drop back to its normal position.

Loosely mounted upon the type-wheel shaft is an arm a, the free end of which is adapted to engage with the shoulder e2 of one or the other of the dial-pins c when the lat-ter is elevated. Above this loosely-mounted arm a is another arm a', rigidly secured to the shaft and having interposed between it and the swinging arm d a light yielding spring aXX, as shown in Fig. 13.

A vertically-swinging arm a2, pivoted by a horizontal pivot to a short extension of the arm a, is formed with or connected to a sleeve or collar aXXX, which encircles the type-wheel shaft, and above this collar is a sleeve a4,

loosely mounted on the shaft and bearingk upon the collar @XXX and having in turn bearing upon it the end of the lower arm of a bellcrank lever G', pivoted to a Xed support G2. (Shown in Figs. 2 and 14E.) The upper arm of the bell-.crank lever G is connected by a link J to a rod G, that extends from side to side of the machine and is supported in vibratory arms F2, pivoted at 5 to a bracket or hanger on the frame, as shown in Fig. 2. Each of the arms F2, near its lower end, is provided with a cam-groove f2, in which works a pin 4c on the end of a lever F", which is pivoted at 2 to the framework andY is connected at its opposite end by a bar F, extending transversely of the keyboard and beneath it to a similar lever on the opposite side of the machine.

One of the pins c of the dial is always in an elevated position with the free end of the swinging arm a against its shoulder c2, being held there by the tension of the spring applied to the type-wheel shaft. The free end Aof the vertically-swinging arma2 normally stands just above the upper end of said raised pin. thus be at all times elevated in order .to arrest the type-wheel shaft andr prevent the Immediately beneath each IOO IIO

It is essential that one of the pins should Q springs which operate upon it from running down.

It is remarked that the combination of rotatable type-wheel, finger-keys, stops for arresting the type wheel, and intermediate mechanism operated by the keys for actuating the stops is such that the key struck for designating a given character will immediately resume its normal position and yet leave the stop in its operative position to arrest the movement of the type-wheel an d that the same key maybe used in succession to redesignate or repeat the same eharaeter as often as may be desired. Assuming, then, one of the pins to be elevated and the type-wheel shaft arrested, if one of the keys of the keyboard is depressed the dial-pin corresponding to said key will be raised through the instrumentality of the end k of the lever lf2, while at the same time the arm F2 by the action of the pin i on the lever F in the angular portion of its cam-groove f will be vibrated, thus causing the bell-crank lever G to be rocked iirst forward and then backward, the forward motion ca-using the vertically-swinging arm a? to bear down upon the upper end of the previouslyelevated pin and to depress said pin. Before, however, the said pin has been suiciently depressed to release the swinging arm a, from its shoulder c2 the ends mx of two arms m' m', secured to the sleeve a", pass in between teeth of a locking-wheel E, secured to the type\\'heel shaft, (shown in Figs. i and 3,) and prevent the shaft from rotating; but as soon as the pin has been depressed sufficiently far to release the said swinging arm a from the shoulder e2 the spring @XX operates to throw said arm a past the shoulder c2 to an extent, however, limited by a stop ai on the arm a'. Upon the backward motion ot` the bell-crank lever G referred to the vertically-swinging arm a2 is thrown upward by the operation of a spring A7, (shown in Fig. 2,) carrying with it the sleeve c" and effecting the release of the locking-wheel c from the hooked ends MX of the arms m an', thereby permitting the type-wheel shaft to rotate until the arm a strikes the shoulder c2 of the pin last elevated, this operation being repeated each time a finger-key is depressed.

It should here be stated that the pins of thc dial have such relation to the characters on the type wheel as that when any given pin is raised from the dial by the operation of its corresponding linger-key and caused to arrest the swinging arm a of the type-wheel shaft the eharaeter on the type-wheel corresponding to the key and to the pin so raised will be brought to the printing -point and stand ready to make an impression upon the paper when the next key is depressed and the next pin elevated, as described.

The paper-carriage N is provided with frictionnrollers R2 and is adapted to travel back and forth in front of the type -wheels upon guide-rails R R4, with which said rollers engage.

The presser-bar .P to which reference has hereinbefore been made, is provided at opposite ends with arms F2, which have bearvibrating arms F2 through the shaft Gand swinging arms Ii5 hung at F't to brackets in the paper-carriage and connected near their middle at N2 to the arms of said presser-bar, as clearly indicated in Fig. 2. A paper-rest l is pivoted to the arms l2 ot' the pres 3er-bar and its lower edge is curved so as to .tit the under portion of the prcsser-bar, a spring P being employed to keep said edge up to the presser-bar with yielding pressure.

The paper on which the impression is to be made is passed between tliepape11'est P' and the presser-bar P, thence over the front of said presser-bar, and thence overa large paper-cylinder C, its margins being held between said cylinder and two small frictionrolls c' c, as shown in Figs. l, 2,'and The feeding of t-he paper is elt'eeted by the rotation of the paper-cylinder C. On the end oi' said cylinder C is secured a ratchet-wheel t, with which is adapted to engage a springpawl if', mounted upon an arm 2, pivoted at if* to the paper-carriage N, and actuated by a rod t, which is in a slotted arm il, secured to the paper-carriage N. The lower end of the rod is provided with an eye or opening in its lower end, through which passes a crankarm if, projecting from an oscillating shaft t7. Motion is communicated to said shaft t7 and to the pawls connected thereto through a rod t, connected to a iinger-key Q, all as shown in Figs. i and 7. After each line has been printed upon the paper the linger-key Q may be depressed, thereby causing the paper-cylinder C to be rotated by the described connections sufiiciently to advance the paper, sc as to bring it in position to receive the im pression of the next line. It will be noted that the crank-arm extends from side tc side of the machine and that although thc rod ti slides back and forth with the paper carriage its connection with said crank-arm i'is preserved and that therefore a depression of the line-key Q will have the effect of shifting the paper in position for receiving the impression of the next line, regardless oi 'the point at which the previous line terminates.

Instead of operating the paper-cylinder-ro tating mechanism by hand, through the key Q, it is generally operated automatically b) means of a bell-crank lever t, pivoted to 2 depending bracket N2, secured to a stationary part of the frame, and a stop X5, secured t( the paper-carriage and adapted upon the return movement of said carriage to strike th( upper arm of said bell-crank lever if an( cause the lower arm thereof to operate upor the crank-arm i, as shown in Fig. 15.

The means for advancing the paper-car ently explained.

riage and the paper thereon after each letter' is printed in the direction of the length of the line a distance corresponding to the width of said letter will next be described.v

M5, Figs. l, (i, and l2, represents a frame secured to the upper portion of the machine and at the left thereof, as shown in Figs. -l and 3. Within this frame are arranged a series of sliding bars or what may be termed quads These quads are formed with reference to the width of the type on the typewheel, one of them corresponding to the width of the narrowest type,two of them to the width of type of next size, and three of them to the width of the largest type; and the function which they perform inthe machine is to cause, after an impression has been made from a given type, the paper-carriage and the paper thereon to advance a distance equal to the width'of said type and bring it in position for receiving at the proper point the impression of the next type. The thickness of these quads may vary and two or more be employed to represent the smallest type and a relativelylarger number for the largest type.

V V V represent three pawls of different lengths having hooked outer en ds and pivoted at their inner ends to arms V3 of a sleeve M3, which is mounted so as to slide freely upon a rod B2. Each of these pawls is adapted to engage with one of the sliding quads q, and to prevent the possibility of more than one quad being caught at a time the quads are preferably `tapered at their upper and lower edges.

This tapering of the edges of the quads also reduces the area of fric'tional surface of their sides.

- V is another and shorter pawl pivoted to a `quads q is further provided with a notch or shoulder V2 on its upper edge near its middle, with which the pin or projection of the short pawl V/is adapted to engage, as will be pres- The shaft B,'carrying the sleeve M3, is adapted to be reciprocated back and forth transversely of its length upon guides M M/ by means of rods B7 B7, mounted upon the upper arms of bell-crank levers B BG, pivoted to a cross-shaft B, the lower arms y of said bell-crank levers being connected by -rods B5 to levers B4 at 5 and connected by a bar Barranged beneaththe pin-frame B2, as shown in Fig. 2.

M2 is a metal piece or bracket arranged at one'end of the paper-carriage N, as shown in Figs. l and 6., and having pins C'1L C5, which pass through corresponding guide-perforation's in the carriage-frame N,and having also a short stud Cadapted to project in the plane of the quads q when the latter are projected,

c and a long arm M2,wh ich rests within a groove in the sleeve M2 and bears at its extremity the roller M4. Upon the pin C5 is arranged al spiral -spring, which bears at one end againsta collar cx on said rod and a lug cy secured to the carriage-frame, as shown in Fig. 0. The tendency of this spring vis to throw the piece or bracket M2 out, away from the paper-carriage frame N, so that its projection C2 shall be in advance of a projection N,formed on said paper-carriage and likewise projecting into the plane of the quads when the latter are thrown outward.

Referring now to Fig. 2, it will be seen that whenever a inger-keyis depressed for the designation of a letter its pin p will depress the spring-pins p2 or p2, as the case may be, beneath it, and said pin p2 or p2 will in turn depress the bar B3 and cause the rod B9 to be pushed forward through the medium of the bars B4, rod B5, bell-crank levers B6, and rods B7. In thus moving forward the bar B9 will carry with it the sleeve M2, thereby causing the hooked ends of one or more of the pawls V V V to engage with the end of the quad or quads beneath them, accordingly as more or less motion is given the bar B3. Then upon the iinger-keybeing released the said pawl or pawls V will be drawn backward, carrying with them one or more of the quads out of the path of the projection C3 of the piece or bracket M2 on the paper-carriage, but not out of the path of the projection N of the paper-carriage, since the latter projects farther than the pro jection C2. As soon as the end of the quad or quads' is withdrawn from the projection C2, a shoulder V6 on each of the pawls by which the withdrawal of said' quads is eifected strikes a rib or bar M15 on the frame M5, and the said pawlsl are disengaged from the quads and at the same time the pin on the spring C5 open ates to force the piece or bracket M2 out from and Yin advance of the paper-carriage and causes said projection to engage with the end of the quad next following the quad or quads withdrawn. lf the letter designated is of the minimum width, the depression of the key will cause one of the shortest spring-pins in the frame B2 to act upon the bar B3 and thus give the minimum amount of forward movement to the pawls V V V and cause the longest only of said pawls to engage with and retract a quad, while the designation of a wider letter will cause a pin in the pin-bar made correspondingly longer to throw two or even three of the pawls V into engagement, so as to retract two or three of the quads.

' rlhe three pawls V are made of different lengths to correspond to the pins of different lengths in the pin-frame B2, and whenever a key is depressed to designate a letter of any one of the three widths one or all of the pawls operate to withdraw partially a number of .quads corresponding in aggregate thickness to the width of the letter designated. I state that said quads are partially withdrawn, by

.which I mean that they are withdrawn far enough to be moved out of the path of the projection C2, but not sufficiently far to withdraw them from the path of the projection N', the latter still remaining in engagement with them.

IOO

IIO

Bearing in mind that according to my process and in this machine, thc printing of a letter does not take place when said letter is designated, but only upon the designation of the next succeeding letter, it will be obvious that the means for gaging or regulating the length of the feed of the carriage corresponding to the width of said letter must be adjusted upon the designation of said letter an d in a manner to become operative after the letter is actually printed. By the partial withdrawal of the quads in the manner above indicated this adjustment of said means is effected. lt remains now to be seen how this feed adjustment is practically applied. After the quads have been partially withdrawn or set up, so to speak, upon the designation of a letter and the next letter is designated the pressure of the key corresponding to said next letter Causes all the pawls V and the pawl V to be advanced, the former operating to engage with the appropriate number of quads, while the pin V5 of the latter rides along the upper surface of the quad or quads set up by the previous operation, and then upon the pressure being removed from the finger-key all the pawls are retracted, the longer ones partially withdrawing or setting up the quads for the letter last designated, while the pin V5 of the short pawl V falls into the notch or notches Y2 of the quads partially withdrawn or set up by the previous operation, and, becoming thus engaged with said lastmentioned quads, operates to fully retract them and carry them out of the path of the projection N of the paper-carriage, thereby permitting the paper-carriage to be advanced or fed forward under the influence of the helical springs within the drums b until the projection N comes in contact with the quads last set up, the extef't of such feed of the carriage being equal to the thickness ofthe quads thus completely withdrawn.

Upon the bar B3, through which the inotion of the vertically-moving spring-pins 192 p3 is communicated to the lever B4, l may arrange an angular plate f, havinga slight longitudinal baek-and-forth movement on said bar B3, being actuated in one direction by a Stop j"2 upon the frame and in the other by a spring f3, secured at one end to the frame and at the other to said plate f. This plate fis provided with a series of openings p8 in its upper portion, which normally stand directly beneath and in line with the spring-pins p2 of the bar B2 and when any one of said springpins is depressed its lower end passes into one of these openings and bears against the bar B3, thereby causing the latter to descend. As soon as the bar B begins to move downward the end of the plate j' strikes the stop f2 and causes said plate to be shifted against the tension of the spring f3 and the edge of its opening to enter a groove in the side of the pin, as shown in Fig. ll, thus securely holding the pin connected to the bar Bs until the finger-key rises, when its disconnection will be automatically effected by the springf, as will be readily understood. The advantage of employing this locking-plate is that it absolutely limits the stroke of the bar B3 to the length of the depressed pin between its head and the frame B2 and prevents the jumping of the bar when the keys are struck with unusual force.

The mechanism for inking the type-wheels is as follows: Referring to Figs. l. and 55, /rm represents a hollow cylinder divided into a lower and an upper compartment by a partition rt", and yr is another smaller cylinder arranged alongside the iirst named and adjacent to the type-wheels. Centrallyof the cylinder frm is arranged a shaft o, which has secured to it near its upper end an arm r2, bearing at its outer end a roller 1", which is adapted when the said shaft r3 is rotated to revolve around in contact with the inner periphery of the cylinder T10 and to come back into contact with an inking-roller r, mounted on an arm u pivoted at u to the casing A, which ineloses the type-wheels. Ordinary printers ink is applied to the inner surface of the cylinder rw, and the roller o" operates to evenly distribute it and to transfer it to the roller fr, which applies it to the type-wheels. Mounted. loosely upon the shaft yr3, near the lower end thereof, is a ratchet-wheel I7"", to which is secured a barrel r4, containing a helical spring, which is connected at one end to said barrel and at the other end to said shaft 1'. A pawl fr?, mounted upon a reciprocating bar frs, is adapted to engage with the ratchet-wheel V5 and wind up the spring within the barrel r, while another pawl 0' serves to prevent backward rotation of the barrel when said spring is wound. Motion is imparted to the bar r by a crank-arm r1, secured to the shaft B, to which the bell-crank levers B are also secured, as before described. (See Fig. 7.) Also secured to the shaft r3 is a fixed arm 711i", which normally is in contact with a swinging tripping-lever or catch r, (shown in Fig. 25,) bcing held in engagement therewith by the stress of the spring applied to the shaft. 'lhe lower end of this tripping-lever stands normally in the path of a cam or projection fr on the barrel r4. The operation of these parts is as follows: Each time the shaft B11 is oscillated, as the result of the depression and release of a finger-key, the bar 0'8 through its pawl T7, acting upon the ratchet T5, causes the barrel r4 to be rotated the distance of one tooth and the spring within it to be correspondingly wound up, and by the time the barrel has made one complete revolution the spring is completely wound up and the cam fr is brought to the point where it strikes the tripping-lever r1? and vibrates it, so as to release the arm fr, whereupon the shaft r3 is permitted to make one complete revolution, or until again arrested by the ire-engagement of the rod rl* with the tripping-lever, an d during such rotation the distributing-roller lrpa'sses once around the innerperiphery of the inkingcylinder T10 and back to contact with the inking-rol'ler 7. Since the type-wheels are required to be shifted up and down for the printingof upper and lower case characters, proy vision has to be made for the withdrawal of the inking-roller 1" from contact with them during such shifting operation. I therefore form in the shifting-rod L (see Fig. 2) two V-shaped notches O O and cause the shorter end of the arma, which bears said inkingroller r, to normally bear against the said rod L. l/Vhen either type-wheel is in printing position, the said arm a will be entered in one or the other of the notches O O and-the inking-roller will be permitted to bear against the periphery of such type-Wheel; but whenever said rod L is shifted, for the purpose of changing the position of said type-wheels, the said arm u will ride out of the notch and swing sufficiently to remove the inking-roller lfrom contact with the type-wheel, and remain quads to be set up. Then the driving `of the paper-carriage back to position to begin a new line of matter, whether done then or at the next use of the machine, effects through the roller M4 the automatic restoration of said quad or quads to their normal positions and adjusts the machine so that upon the depres-` sion of the first key at the beginning of the newline the paper-carriage will not be advanced at all, but will `remain stationary until the second letter is designated. Suppose it is desired to write the word The at the beginning of a line. The operation will be as follows: The operator will rst press upon the bar B, which will causev the frame B2 to be advanced, so as to bring the appropriate pin i 5o p3 beneath the spring-pin p of the key used for designating 'l, and cause the rod L to be lifted, so as to bring the lower type-wheel into printing position in front of the presserbar I). Then, while the said bar B still remains down, he will depress with his other hand the key representing T, which will cause the bent end of the appropriate lever K2 to project from the dial the corresponding dial-pin, the lever F to operate upon the swinging lever F2, and cause, first, the presserbar to make a dead-stroke toward the typewheel secondly, the vertically-swinging arm a2l to depress the dial-pin representing the space on the type-wheel and disengage from said pin the laterally-swinging arm a, and, thirdly, the ends m of the arms m to engage with the teeth of the locking -wheel E and hold the type-wheels and type-wheel shaft firmly from rotation and cause the bar B3 to be depressed, so as to effect through the intervening devices the engagement of the appropriate number or quads by the three pawls V V V. All this takes place upon the depression of the key used to designate 'l. Vhen, then, the said key is released and permal position, and in so doing will cause the vthree pawls V V V to withdrawthe appropriate number of quads from the path of the projectionC3 and permit the piece or bracket M2 to advance until said projection C3 strikes the lneXt quad in its path. The single pawl V on this lirst stroke will perform no function, but will be left ready to act at the next stroke upon the quads just set up. The pin 4 on the end of lever Finpassing through the upper port-ion of cam f will cause the lever F2 to recede andremove the presser-bar P, with the paper, from contact with the type-wheel, and at the same time through the rod G and link J raise the end of bell-crank lever G from off sleeve a4, thus allowing the ends m of the rods m to be receded or disengaged from locking-wheel M, and thus permit the typewheels and shaft to rotate till the arm a engages with theshoulder e2 of the dial-pin just set up by the designation of vthe letter T, this operation bringing the letter T on the lower type-wheel to the printing-point, and

Athe key K2 will also fall backto normal position. -When the next letter h is designated, the preceding letter T will be printed, the paper-carriage advanced by the withdrawal of the quads from in front of the projection -N a distance corresponding to the width of the letter T 7 j ust printed, and the letter h on the upper wheel will be brought to the printing-point, and so in like manner will the designation and printing of theV letter e7 take place. v A

In the example just given it will be noted that before the designation of the letter T 7 the bar B is required to be depressed in order to bring'the lower printing-wheel bearing the capital or upper-case letters to the printing-point. In this operation the pin /L' on the shifting-rod L passes'above the arm of the bell-crank lever h, and upon the press- Vmitted to rise, the bar B3 will resume its nor- IOO IIO

ure being removed from the bar B the said 1 pin t' will rest upon the arm of the bell-crank lever 71, and thus hold the rod L and connected parts elevated. Of course the'pressure should not be removed from the bar B until after the key designating the letter T is struck.

W'hen the letter h is designated by the striking of its appropriate key,` the movement of the lever F consequent thereon will through the rod g cause the pin-wheel h to be rotated and the bell-crank lever hto be vibrated, thereby releasing the pint' and permitting the rod L and its connections' to descend. Such release of the rod L' of course takes place in point of time after the impression has been made of the letter T.

It will of course be understood that durin g the operation of designatin and printing just described the ink distributing and applying d evices will be worked in the manner hereinbefore described.

\Vhen the paper-carriage has advanced to its fullest extent, (which will be at the completion of a line,) it can be returned to startin g-point either by hand or by the operation of a foot-treadle, and as the result of its return the springs for actuating it, as well as the springs which serve to impart motion to the type-wheel shaft, will bewound up, as before described. As a further result of the return of the carriage the wheel M4 on the end of the arm )l2 will operate upon the quads retracted during the printing of the last line and cause them to be projected again in normal position.

The advance of the paper for the printin of the next line is effected by the mechanism described, either automatically or by hand, as before mentioned.
