TYPE-WRITING MACHINE.

SPECIFICATION forming partof Letters Patent No. 357,090, dated February 1, 1887.

Application filed August 19, 1885. Serial No. 174,819. A(No model.)

yTo all whom it may concern.-

Be it'J known that I, N. GRIER MOORE, a citizen ofthe Uni tedStates, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in TypeWriting Machines; and I do hereby declare the following to be such a full, clear,and exact description of the invention as will yenable others skilled in the art to which it appertains to makeand use the same.

This invention relates to that class of type writing machines in which the type or letters are secured to the periphery of a disk and the paper-roller is caused by a movement ofa hand`lever to, oscillate and impinge iagainst said type, anrdhas for itsobject the simplification of the various parts, hereinafter mentioned, so as to insure a more perfect machine, exact in its every movement, producing 'as-little friction as possible, and requiring the minimum of power by the operator.

My invention will be more fully understood by reference to the accompanying drawings,

forming a part of this specification, and in which similar letters of reference indicate like parts throughout the several figures.

In said drawings I have illustrated, in Figure 1,a plan view of a machine embodying my invention, at Fig. 2 a side elevation of the same, and at Fig. 3 a central vertical section thereof. At Fig. 4 Ihaveillustrated the spacing device,*at Figs. 5 and 6 the disengaginglatch to permit the return of the carriage, at Figs. 7 and 8 the plate through which the inkribbon is laced, at Fig. 9 the device for revolving the upper ribbon-reel, at Fig. l() the end of said reel, showing the locking-catch, at Fig. 11 a sectional view of the operating-lever and latch for the index-wheel, and at Fig. 12 the manner ofinking the types when noribbon is employed.

In said drawings, the letter A represents the frame of the machine, and A the type disk or wheel loosely mounted on the hub ofan inclined table, a, so as to easily revolve thereon. This table is rigidly supported above and on the frame A by the supports or legs A2.

The type are secured to the edge of a ring, a',

which ring is placed on the type-disk A', and securely heldin position by an annular ring, a2, secured by screws or other suitable means to different type-rings.

collar, a4.

said disk, and having a flange thereon which projects partially over said type-ring a. The type may be secured in any convenient manner to the type-ring a'; but Iprefer to make 55 an electrotype strip containing all the required letters, numerals, &c., and secure said strip to the periphery of the said ring a. Each Inaohine may be provided with several such rings having different styles of type thereon, and the 6o.

change from one style of type'to another may be very quickly accomplished by simply removing the fiange-ring ai.

The inclined shaft A3 is round at the lower r and square at the upper end. The lower end is stepped in a bearing, as, in the frame of the machine, so as to move or slide therein. The upper square portion passes through an open ing in the table a and projects Aabove it so as to permit the non-revolving index or disk A* 7o to be secured thereon. this disk or index Af, I make the same number of letters, numerals, Src., as there are type on the type-ring a. These characters may be Onthe upper face of indicated on the disk or may be printed on a removable paper or metal ring, which could tit in an annular' recess in said disk, the number of index rings corresponding with the On the periphery ofthe index-disk A4, I providel a number of notches, 8o

equal to the greatest number of type or characters which any one type-ring a may contain. These .notches are made of peculiar shape, as illustrated iu Fig. l, for the purpose hereinafter mentioned. 8 5

The shaft A3 is provided on its square portion below the disk A4 with a collar, a", having a ange at its lower edge. The operatinglever B straddles this collar, rests on the an'ge,

and is provided atfone end with the button b, 9c

Below the collar a4 95 j ated pawl, c, which engages with one end of the spacing-lever B'. This lever is pivoted, as shown in Fig. 4, so as to permit the pin's b2 and b3, with which it is provided,to engage the pinion B`-. A spring, b4, tends to keep the pin lf2-in engagement, as shown. 'Ihe collar c* is also provided with a groove or slot, al,

wherein the roller c, secured to one end of the carriage oscillati n g lever C, may travel. This lever Cl is pivoted at c' to the frame, and at c2 it engages the rod c:s of the carriage. The end of the lever C may be bifurcated so as to straddle the rod e3,- or it may be provided with a yoke or clip,as shown. The carriageframe is supported by friction-rollers at the rear on the guideway C, supported on. the frame A by means ot' brackets, and its front cud is supported on the rod I, which is secured to the frame by standardsv I. At the front end of the carriage is hinged the rack-bar C2, which meshes with the spacing-wheel C3. The wheel Ca is only revolved one notch or tooth at a time, as will hereinafter lnore fully appear, and causes the rack-bar C2 and carriage C8 to travel longitudinally across the machine, as desired.

The pinion B2 and spacing-wheel C3 are mounted on opposite ends of the shaft b5, as shown in Figs. 2 and 3, at right angles to the path of the carriage. As the spacing-lever B' is moved either by the operator or by the upward movement of the collar a* the piu b2 thereon disengages from the pinion B2, while the pin b3 enters a space between two of the teeth of said pinion. A tension device causes the rackbar C2 to revolve the spacing-wheel C3, thus communicating motion tothe pinion B2 through the shaft b5. As the operator ieleases the lever B the spring underneath the sameraises the lever and forces the pin b'into the next space on the pinion B2 as the latter is revolving. This will lock the pinion again. When the shaft A is raised, the pawl a6 on the collar a* is forced by its spring to and -agaiust the curved arm of the spacing-lever,

and thereby forces said end over in the direction indicated by the arrow, engaging the pin b3 and disengaging the pin b2. 'Ihe lever is returned, as previously explained.v

At each end of the carriage I pivot a bellcrank lever, C, between the short arms of which is mounted the rod c, hereiubefore mentioned. The other arms of the levers support the paper-roll C5 and are connectedy by the bar 0*. The paper is fed by hand to the roller iu the usual manner from the bottom` and soon engages with the friction-roller CG. rIhis roller C is as long as the paper-roller, and is held so as to easily revolve by Hat spring-arms Clparallel to and against the paper-rollcr, as shown. To move the carriage rapidly or to return the carriage to the point of beginning, it is only necessary to disengage the rack-bar C2 from the wheel C3. This is accomplished by means of the thumb-latch or lever D', pivoted to the carriage and having a tongue orlip, d, beneath the end of said bar C2.

A spring, d', pressing on the lip d, may assist to keep the latch in its normal position, as illustrated in Fig. 5.

Beneath the carriage, at about the center, I secure one end of the cord D2. This cord after passing over a pulley, d2, secured to the frame A, is secured to4 the long end of the lever E. This lever is pivoted beneath the frame near the front end, and the short arm is attached to one end of a tension-spring, E, while the other end of said spring is secured to the adjusting-serew 2. The lengths of the arms of this lever E and the position of. the spring with relation thereto are illustrated substantially in the drawings lin Fig. l, and are such as to cause a steady tension on the carriage through the length of its travel. In the position illustrated the spring is extended and exerts its maximum of strain, and when the carriage is moved farther to the left of the operator the spring contracts, and the loss of its tension is compensated by the gain in leverage.

The paper-roll is turned so as to present a new line to the type by the following means: A trip-lever, D3, is pivoted to one of the levers C, preferably at the lethand side, so as to be near the thumb-latch D', and carries on its long arm a pawl, d, and spring. The spring d* keeps the pawl d in engagement with cir- Y cumferential ratchet-teeth on the end on the paper-roll C5. Stops d (ZT are provided on the lever-arm C* above and below the trip-lever D, the lower one being made adj ustable,so as to regulate the throw of the trip-lever D3. A spring, d5, tends to keep the trip-lever in position, as shown in Fig. 2.

The type are inked in the usual manner either by an ink-ribbon or by an ink-roller. When the roller is used, I prefer to employ the mechanism illustrated in Fig. 12. This consists in mounting the ink-roller niovably in the end of a lever, F, which lever F is operated from the rod c of the carriagc,as shown in dotted lines in said figure. The lever F is supported from the main frame A by aproper bracket. When the ink-ribbon is used,lprc fer to lace the ribbon through slots in a plate, F', to secure proper tension on the ribbon. This plate F is held in front of the type about to be used and between it and the paper-roll, and may be supported from the frame, or, as I have shown, from the table a by means of brackets.

In order to prevent more than one type from impinging against the paper when the paperroll is brought up against the typewheel, I provide said plate F with a cross-bar, f, having an opening, f, which is only large enough to permit one type to pass through it. The ribbonspools are mounted on shafts secured in a frame and supported from the mainframe A. The ribbon is automatically passed from one spool to the other, as follows: Integral with or secured to each ribbonspool is a barrel-pinion, G, as long as the ink-ribbon is wide. These pinions, as well as the spools, are loose IOO IIO

IZO

on their shafts so as to be moved lengthwise thereon. The shafts are provided with a number of annular notches or grooves, into which iit the spring-dogs g, pivoted on the end of the 'spool or pinion.

, The ribbon may be moved from side to side, so as to use every portion thereof by simply lifting the dogs g from the notches and sliding the spool and pinion longitudinally o n the shaft and then dropping the dogs g again into another notch. Pivotedto the spool-holding `frame and below the spool is the arm G, which carries the pawl g. The pawl engages with the teeth of the barrel-pinion G on one side, while the spring g2, secured to the frame, is provided withla curved end, so as to engage two teeth of said -pinion at the same time, as shown in Fig. 9. 'Vlien the paper-roller is tilted forward, as shown in dotted lines in said figure, a spring, g3, pressing on the arm G', forces said arm downward and carries the hinged pawl gaway from one tooth of the pinion over against another tooth, the spring g2 preventing any tendency of the pinion to revolve. As thelpaper-roller returns after strikingthe type, the cross-bar c4 engages the arm G andy forces it'back to its normal position, as shown in full lines in said Fig. 9, and at the same time the pawl g revolves the barrel-pinion against the pressure of thefspring g2. Th us the ribbon is automatically wound around the upper spool, presenting afresh ink-surface to the' type at each stroke. The lower ribbonspool is precisely the saine in construction as the upper one7 but the operating pawl is hinged to one end of the lever G2, which is pivoted to a bracket secured on the main frame v A. The other end of this lever G2 engages the rod c3. When the ribbon is being wound on the upper-spool I throw the lower pawl out of engagement, as indicated in Figs. 2 and 3, and when the ribbon is to be wound on the lower spool I engage the lower pawl and disengage' the upper pawl. Then each movement forward of the paper-roller lowers, through Vthe rod c3, the forward or pawl end of thelever G2, and the ribbon-spool is revolved ou the return movement thereof. Y

The device illustrated in Fig. 1l. is for the purpose of locking the type-disk in position during the printing of the letter or character, and consists of abent locking-lever, H, pivoted to the revolving type-disk. A spring, H4, on

said disk tends to keep one arm, H', of said lever up against theunder side ofthe operat- -ing-lever B. The other arm, H2, extends disk is shapedas shown in Fig. l, so as to pre- Sent an inclined portion on either side. When the shaft A3.

the portion h enteringA said disk between two teeth, thus locking thetype-disk to the indexdisk. When, the operating-lever is moved farther downward, in order to make an impression, the index-disk is of course `movedy downward with the shaft, the portion h being now parallel to the sides of the teeth of said wheel, and permitting the wheel to slide thereon while remainingloeked with the type-disk. A slot or opening, h2, is made in the operatinglever, to permit the bent end of the lever H to enter at this time. Pulleys i on each end and beneath rthe roller C5 are secured to the arms C4, and running from these pulleys over pulleys on the ends of the friction-roller C6, are tapes or endless bands z".

The operation of myinvention is as follows: The-carriage' .being at the right-hand side of the machine, as shown in Fig. l, and the inkribbon'and device for operating the same being placed in position, I take a sheet of paper to be printed upon and feed the same in beneath the roller C5 until the paper is caught by the roller G6. I then take hold of the operating-lever B and turn it around until the index-point is opposite the letter indicated on the `index-disk which I desire to print on the paper. The operating-lever, being hinged to the type-disk, as explained, causes the said disk to revolve with it. The index-disk, the

type-disk, and the operating-lever are so arranged and adjusted with relation to each other and to the shaft A3 that whenever said lever is revolved around -the circumference of the non-rotating index disk to any point the same movement also causes the type-wheel to revolve, so as to present to the opening the type which is indicated or marked on the indexdisk at the `point where the operating-lever is brought to a halt. By pressing down on the lever the shaft A3 is moved downward, and thus the paper-roller is oscillated by means of IOO the lever O and connections heretofore pointed out, and before the paper-roll strikes the type the arm or dog H2 has securely locked the type-disk. It will be observed that the power applied" by the operator to the lever is only such as is required to overcome the force of the spring aiand to tilt the paper-rollerforward to impinge against the type to make animpression.-

Now the operator may relax his pressure on the lever and the rest of the work is performed automatically-that is to say, on thereturn movement of the shaft caused by the spring a?, the entire carriage is caused to move longitudinally the space of one-type through the medium of the rack C2, spacing-wheel B, pinion C3, lever B, and pawl uson the collar a4 on rIhe spring H* beneath the arm H forces the dog orlatch H2 out of engagement with the index-disk, and the ribbonspool is revolved ashortdistance, as explained.

IIS

The operating-lever is then swung around the index-wheel to the next letter pressed down, and so on, till the end of the line has been reached on the paper. The thumb-latch D is then pressed downward, the rack-bar disengaged thereby from the spacing-wheel C3. and the carriage moved back tothe right-hand Yside ofthe machine against the pressure of the form shown in Li'or thc purpose et' insurg ing the perfect working of the locking-lever g H. The sides of the teeth of the disk are bcveled and the front of the lever III bei ng pointed,

Ait will be seen that the lever will enter between two of the teeth ofthe disk A* and bring the type-disk A to the proper position thereby.

The index or pointer Jis pivoted to the operatinglevcr at a point where the lever is connected with the collar a, so that it will move up or down with the index-disk A4, and at the same time when the lever is revolved on the collar fri the pointer J will also revolve with The end ofthe index J is slotted, so as to permit the locking-lever H to pass through itand cuter between two of the teeth of the index-disk A4. If the pointer J is rigidly secured to the lever B, the bent portion which passes around the edge of the disk A" should be extended above said disk sufficiently to -clear it when the lever is pressed downward; but I prefer to pivot or hinge the pointer, as Shown.

For the purpose of ready adjustment the pawl en may be attached to an independent collar, so that the throw of the papcr-roller may be altered without altering the spacing device.

For the purpose of regulating the blow of the paper roller or platen against the types and to make the impression even, I attach buffers K, with'cushions or springs 7U at the faces in such a position as to receive a portion of the blow when the roller is oseillated for the purpose of printing. In a former ap,- plication for patent upon improvements in the same class of machines in which the type are inked only by a roller, I showed buffers for a like purpose attached to the stationary hub of the type-disk. 'lhe present improvement contemplates cspceially the use of ribbon-inkers, one of the objects being to enable it to mani fold in printing. In the position shown in the fermer application the buffers impress themselves through the carbon-paper used in manifolding, and mal-:e the duplicates illegible. For this purpose I attach the buffers K to the carriage, and in two forms, one attached so as to receive the stroke of the long arms C of the bell-crank levers carrying the paper-roller,

and the other receiving the the short arm.

The buffers are made adjustable by aslot in the .short arm, set iu position by a thumb 0r set screw, the buffers being pivotcd loosely to the frame. I do not wish to limit myself, how ever, to such construction, as other modifications for producing the same result will readily suggest themselves to those skilled in the art to which this invention relates, land which may be used without departing from the spirit of my invention.

The inking device illustrated in Fig. 12 may be used with great advantage in this class of type-writing machines; but I do not herein claim such device, and any claim or claims thereon to which I may be entitled are hereby expressly reserved for another application.

The type-ring a', it will be observed, is made so as to be easily removed when it is desired te change the style of type used. The type may be of any suitablemetal or hard rubber that will permit of its being bent around the periphery 0R the ring a. This ring may be secured in place on the disk A by the flangering a2, or may be retained in position by simply iittiiig snugly over a shoulder or recess formed or turned on the disk, and perhaps a pin holding it in place, so as to prevent its being turned around on the disk A.

That I claim as my invention, and desirelto secure by Letters Patent, is as followsi l. Ina type-writing machine, a disk mov ably secured to the frame ofthe machine and provided on its periphery with type, an indexdisk rigidly secured above said type-disk to a non-rotating shaft, and a lever hinged at one end tothe type-disk and-loosely encircling said shaft between the index-disk and the typedisk, whereby the latter may be'revolved by said lever, substantially as and for the purpose specified.
