No; 843,831. Specification of Letters Patent. Patented Feb. 12, I907.

Application filed February'Z, 1905. Serial No. 243,834;-

State of New York, have invented a new and useful Improvement in Type-Writing Machines, ofwhich the following is a specification.

This invention relates to ribbon mechanisms for type-writing machines, and more particularly to mechanisms for feeding the ribbon lengthwise and vibrating or moving it into and out of operative position in front of the printing-point in visible-writing machines in which the type-bars are a'ranged to produce the impressions at a point on the' platen where they can be seen by the operator when the ribbon is moved away from its operative position over or in front of the printing-point.

The principal objects of the invention are to so connect the key-action and ribbon mechanism that the least power is utilized in the operation of the ribbon, thereby insuring a light touch and rapid easy operation of the machine; to provide simple, efiicient, and.

desirable means whereby the ribbon can be vibrated to expose the writing after each im-, pression or only upon the actuation of a key independent of the type-operating keys; to adapt the machine for the use of a narrow light ribbon, which is vibrated with each impression, or for a wider and heavier ribbon, which is vibrated only by the actuation of a special key or space-key; to provide a ribhon-vibrator free from working joints, thus reducing the power necessary for operating it; to relieve the type-bar keys of the work of feeding the ribbon lengthwise; to provide a simple and desirable printing-point index, which can be operated as desired to indicate the printing-point either after each impression or upon the actuation of the specialop crating-key for the ribbon-vibrator, and to improve the ribbon-operating mechanisms of type-writing machines in 'the various articulars hereinafter specified, and set fort in the'claims. These objects are accomplished in part by providing the machine withtwo bars or partsarranged beneath and adjacent to the platen-one a universal bar operated by the several linger-keys and the other 0perated by the space-key or a special key, and

each constructed to support and operate a ribbon-vibrator; by operating the ribbonfeed mechanism by a motor or power device in which power is stored by the'actuation of the space-key and which relieves the finger keys except of the slight work necessary to control the operation of the "motor or power device, and by providing an oscillating printing-point index adapted to be operated, as

described, by either of the operating bars or parts for the ribbon-vibrator.

. Like letters of reference refer to like parts in the several figures.

A represents the frame of the machine, .which'may be of any suitable shape and construction; B, the platen, which, as usual, is

front of the carriage and are operatively con-.- I,

nected to the type-bars. I

The machine illustrated is Y of that kind in which each type-bar is provided with two type and the carriage is mountedon ashiitframe D, which normally holds the platen up in position for printing with the upper-case type at the outer ends of the type-bars and is shiited downwardly (by means not shown) for printing with the inner or lowercase type. lhe type-bar action (illustrated in" Big. 2) is fully show 11 and described in my ap plication for United States" Letters Patent, tiled January 17, 1905, Serial No. 241,456, and it is sufhcient here to say that the fingerkeys are arranged in banks or rows running transversely or the keyboard, and each key is mounted to reciprocate vertically on a keyleverF and linkf. V a l G represents the universal bar or part operated by the finger-keys for tripping the carnage-escapement to effect the letter-spacing. The bar 1s arranged at the central portion of the machine, preferably extending from a point beneath the front'portion of the keycard upwardly and. rearwardly passing. over the type-bar segment between, the twocentral type-bars and beneath the platen. The bar shown consists of two narrow strips of sheet metal arranged side by side, with their front ends spread apart and pivoted to arms 9 one rock-shaft g, journaled in suit-- able brackets g on the front of the frame,- while the rear end of the bar is pivoted .to an arm or lever g which is pivoted on a bracket 9 on the back of the frame and trips the oar-- riage-escapement by a rearward thrust of the bar. The universal bar supports a rib hon-vibrator, and the object of spreading its front end is to better hold the bar and its vibrator in proper upright position. Inthat portion of. the bar passing over the segment the strips areseeured fare to 'faoeto make the bar narrow, so as not to interfere with the type-bars, while in that portion of the bar underlying the keyboard the strips are spaced apart and connected by transverse rivets or pins 9 for the engagement of arms on rock shafts H for actuating the universal bar. The latter is held in its normal forward position and retracted after operation by a coil l spring 9, connected to a rod joining the i swin ing supporting-arms for the front end of the bar and to the l'ront of the frame. In-

' The actuatingrock-sharts .H "for the versal bar (see Fig. .l) are arranged trans"? verselyunder the keyboard, one beneath the .fulera of the key-levers for each trans- 'verse row or bank of finger-keys, and. are

journaled on their ends in suitable bearings h at the sides of the frame.

Each rock-shalt 4 has a depending central arm h, which engages front arms of the key-leversF'andbear againstthe lower ends of the stems of the several finger-keys in one row or bank, so that When'any' key in the row or bank is depressed the shaft H beneathit will be rocked and thrust the universal bar rearwardly to the position shown in Figs. 1 and 10 to trip the carriage-escapement; The rock-shafts I are returned to and held in tl'ie g'n'ormal one of the pins g of the universal bar, and a 4 series of arms h, which are parallel with the position by suitable springs hiliig. '1. A

separate ur'iiversaLbanaetuating shaft H for each row or keys is preferred, because the bar with one aotuatingshait is lighter-and easier to operate than would be a bar'and. actuating device or mechanism common to all of the keys but for the purpose of this invention the universal bar could be reciprocated by other actuatlng means or parts.

' I represents the space-key, or key for tri ping the carriageesoapement to effect t e spacing independently of the type-bar action. The space-key preferably has two vertical stems pivoted to arms'i on a rock-shaft 'L', journaled in the brackr-zts-g on the front of' the frame, and. is 'held'in and returned after actuation to its normal raised .pos'ition'by a suitable spring '5 connected to one of the arms "i anaito the frame. I Y K represents a bar or part, hereinafter termed the space-bar, 1 which is located at the central portion of the machine, preferably over and extending intlle same general di reotion as the universal bar G. The space bar, like the universal bar, is'preferablymade of two strips of sheet metal'or a folded strip of metal, the two strips or portions being-arranged close together, except at their rear. endsfwhich spread apart. The front end of 'the -spaee-bar K is offset upwardly to pass-over the rock-shafts H and is pivoted to an upwardly-extending arm k on there's sha-ft 'i for the sp ace-key, and its forked rear end is pivotezlto arms on a roel-:shaft is, which is journaled in the bracket gi on the back of the frame and has an arm it' which acts to trip the oarriage-escapement each time the space-key is depressed L The forked rear end. of the s pacebar, like the forkedfront end of the universal bar, holds the space-bar in upright position. constitute supports for ribbon guides and vibrators, and the former reciprocates end The two bars K and G ent key I is operated, the gui as hereinafter explained, and the ribbon is supported between the spools and adjacent to the printing-point by a guide and vibrator, which may be supported and actuated by either the universal bar or the space-bar, The guide and vibrator M (shown in Figs 1,

l The vibrator M can be adjusted up or down eral different lines along the upper side of l the ribbon may be moved into position to i receive the impact of the type at the outer ends of the type-bars and still leave the central and lower portion of the ribbon in posil tion to receive the impact of the inner type on l the bars when the platen is shifted down- 1 wardly for printing with the inner type. By 3 interchanging the ribbon-spools in the usual l manner the less-worn portion of the ribbon can beplaced uppermost to completely ex- ,haust the ribbon. As the space-bar K is l normally held rearward, the vibrator thereon retains the ribbon over the printing-point at all times except when the space or independent key I is depressed, at which time 2, and 8) is secured to the universal bar and the ribbon is moved forwardly and downconsists of a single piece of sheet meta" .having a forked upper end provided wit up right guide slots or openings at, through w ioh the ribbon passes, and a depending shank m, which enters and is detachably retained in a flanged upright hol er m 'lixed to or formed on the universal bar. The shank of the guide and vibrator is preferably bowed, as indicated at M Fig. 4, and of spring temper and is held in adjusted positions in the holder by the friction between these parts. When the universal bar is in its normal positioh, (shown in Fig.2) the guide and vibrator holds the ribbon in front of and below the printing-point, exposing the line being printed to view. When the universalbar is moved rearwardly by the operation of a finger-key, it carries the vibrator and ribbon with it, holding the ribbon directly in front of or over the printing-point at the instant the typ e-bar makes the im ression, This vibrator is exceedingly light in weight and with a narrow ribbon, such as shown in Figs. 1, 2, and 8, adds very little work to the type-bar action and insures a light touch and easy operation of the fingerkeys. The absence of working joints in the ribbon-vibrator contributes considerably to the easy movement of the ribbon and. entirely l prevents wear in this part. With the vibrator'secured to the universal bar the ribbon is vibrated or movedto expose the writing after each impression.

When it is'desired to vibrate the ribbon'to expose the writing only after a word has been written, or when the space-kc or independe and vibrator M is-detached from the universal bar G, and it, or preferably a similar guide and vibrator M, Figs. 3, 6, and 7, adapted for a wider and heavier ribbon L, is attached to the spacebar K. The latter is providedwith a holder m, similar to that on the universal bar, in which the bowed spring-shank of the guide and vibrator is adjustalby held by friction.

wardly to expose the printing. The spacebar is mounted to move forwardly a greater distance than the universal bar and also I downwardly, so that the printing is fully exposed, even when the wide ribbon is adjusted to its 'highest position. The universal bar is arranged to reciprocate nearly in a straight line, as it is not necessary to lower the narrow ribbon much to expose the printing-point. for the universal bar could also be arranged to cause the universal bar to lower, as well as move forwardly A narrow light ribbon could be used with a guide andvibrator on the space-bar; but as the type-bar action is relieved of the work of vibrating the ribbon the added weight of a wide ribbon is not of so much consequence, while the wide ribbon lessens the cost and work of changing ribbons. With the vibrator on the space-bar the printing-point is exposed at the end of each word and whenever the carriage is moved a letter-space after the'use of a punctuation-mark,- and it can be exposed atany key without causing the carriage to-.move. Many operators prefer to thus vibrate the [ribbon rather than have the ribbon constantly vibrating before them and increasing the work on the'type-bar action.

The described construction of the ribbon guides and vibrators and their holders is simple and efiective; but guides and vibrators of other construction and other means for detachablyconnecting them to their supporting and operating bars could be employed;

rinting-point. o is an integral arm on tlie in dex, which projects downwardly and bears against a rearward projection on a post P, secured in the vibrator-holder m on the space-bar, and is'thereby held down away from the platen, as shown by full lines in ii 2, when the narrow-ribbon vibrator M is in use, except when the space-bar K is moved forwardly by the depression of the space-key. The wide-ribbon vibrator M is provided with a similar projection P (see vibrator and the wide ribbon are used. When either the post 1? or wide-ribbon vibrator M are used, the index is held out of action, except when the space-key I is dethe work of operating the index.

if it is desired to raise the index to operative position after each impression, this can be done by providing a ribbon-vibrator M Fig. 5, for the universal bar, with an o era-tprojection I 'for the index. Witli this vibrator in use the index is moved downwardly away from the platen each time the universal bar is moved rearwardly with the ribbon and allowed to be swung up by its spring when the universal bar moves forwardly with the ribbon and exposes the printing. The ribbon is fed lengthwise or wound slowly from one spool onto the other by mechanism preferably constructed as fol lows,(see Figs. 2 and 8 12 Q represents up site sides of the machine and journaled in suitable bearings q in the upper portion of the frame, and q in a cross-bar (fat the lower part of the frame. The spools are placed on the upper ends of these shafts, to which they are splined or otherwise detachably secured so as to turn with the shafts. When the narrow ribbon is used, the spools are held at the proper elevation by suitable washers (1 which are omitted when using the wider ribbon and spools. represents slotted guides, which are removably secured, to the frame acent to the spools to lead the rib bon onto the latter. Secured to the lower ends of the spool-shafts are bevel get r-wheels 2, adapted to mesh with. and bedriven by bevel gear-wheels 'r, secured to a horizontal drive-shaft R, journaled at its ends in suitable bearings r in the frame-bar 12 The central portion of the shaft passes through and bears in holes in two lugs r 1", rising The drive-shaft is and when moved one way the gear-wheel at one end will mesh with the gear-wheel on the adjacentspool-shaft and drive the latter, while the opposite movement of the driveshalt will cause the meshing of the other gQztY-WliutlS and the driving of the otherl shownbut will spool-shaft. This arrangement of the spools and operating-shafts is common, and any other means for positively driving either spool as described may be employed S represents a spring-barrel, which is loosely mounted to turn on the drive-shaft between the bearing-lugs r 1- and adjacent to one of them, 1, which is referably provided with a disk portion w ich closes one side of the barrel. The latter contains a spiral spring s connected at its inner end to the hub of the barrel and at its outer end to the adjacent bearing-lug r. The barrel has a peripheral flange s provided for the greater part of its circumference with ratchetteeth, but having a smooth or untoothed ortion 5 see Fig. 11. s is a small ratc etwheel screwed on or'otherwise fixed. to or formed on the spring-barrel, and T is a toothed escapement-wheel between the spring barrel and other bearing-lug r and splined or otherwise secured to the drive-shal't'to, turn therewith while permit-ting the described endwise movement of the shaft. The escapement-wheel carries a pivoted springpressed dog I, which engages the teeth of the small ratchet-wheel of the spring-barrel. The teeth of the small ratchet-wheel extend in the same direction as the teeth of the flange 8 of the spring-barrel, so that the lat ter can. be turned independently of the es,-

capement-wheel in a direction to wind the spring-that is, forwardly in the construction drive the escapementwheel and shaft B when turned in the opposite direction byits spring 8. Other clutch devices permitting this action would answer.

U represents a pawl pivoted to the spacebar K, with its lower end depending forwvardly toward the toothed flange 8 of. the

spring-barrel," but normally held out of engagement therewith; as by a pimp, project from the bearing-lug r. The rear portion 0 the pawl is preferably forked to straddle the universal bar. i

V is an escapement-lver pivoted on a projection of the bearing-lug r and havingv two pallets to engage the teeth of the escapement-wheel T and an arm which extends up between the two parts of'the universal bar and between an operating-pin o and another pin, which is preferably one of the transverse pins the arms of the actuating rock-shafts.

The action of this ribbon-drive mechanism is as folllows: With each depression of the space-key and forward movement of the space-bar K the pawl U engages the teeth of the flange 8 on the spring-barrel and turns the latterforwardlya distance equal, for ing of the bar, which are engaged bystance, to four of its teeth and wi'nds the springto that extent. The dog t-holds the spring-barrel against backward movement except as permitted by the escape'ruent, and

at this time the cscapementdeverv acts seaesi bar G the pinsuforces theescapementelever back to normal position and permits'a farther movement oi the escapement-wheel,

the complete movement of the universal bar allowing the esoa ement to move the extent of one tooth his movement carries the drive-shaft R and spool in gear therewith a corresponding distance and feeds the ribbon a step lengthwise. The ratchet-teeth on the escapement-wheel are shorter than those on the spring-barrel, so thateach timethe pawl U turns the barrel a distance equal to four teeth on the barrel the springis wound and power is stored enough to drive the escapement-wheel a distance equal to six or its teeth and move the ribbon for six impressions, or enough for a word of slightly more than the average number of letters. As the spring is wound to the same extent when using the spaces-lever after a punctuationpoint as for a word, the result is that the spring-barrel is soon turned until the smooth part of the flange on the spring-barrel is brought under the end 01 the pawl U and the spring completely wound up, after which the pawl can only act to wind the spring as much at each depression of the space-key as the escapement-ratchet has permitted the springbarrel to turn backwardly. The spring-barrel turns backwardly with the eseapement-wheel and forwardly independently of it, the barrel having an'mtermittent oscillating motion and the escapement-wheel an intermittent rotary movement. If the.

barrel has moved back but a single tooth after the spring has been fully wound, the pawl U takes it forward that much, and if more than one tooth up to four have turned back within reach of the pawl it takes them forward with I the next depression of the space-key, thus keeping power enough stored to feed the ribbon for about thirty impressions, and except in the case of sev eral words of unusual length being printed successively the ribbon moves with each character printed. The power stored is sui iicien'; for any'pi'obable casejol that kind,

but the proportions oi the parts may be changed to provide for a longer, continuous run, if desired. Inuse thispower device:re lieves the type-keys from all but-the slight est part of the work of feeding the ribbon and tends to render the machine easier to operate, capable "of greater speed, and of greater powerful manifolding.

With each rearward movement The ribbon does not feed with each movement of the space-key, but does so with each impression of a type-bar.

Power mechanism analogous to that described for'feeding the ribbon, and inwhich power is stored by'the actuation of the spacekey or a special key and is liberated or controlled by the actuation of the type-bar keys, can withslight changes or rearrangement for; the parts be adapted to machines in which the ribbon arrangement is inherent "fromthat described and whether the ribbon is vibrated or not.
