. Specification of Letters Patent.

Patented Sept; 29, 1908.

Application filed January 29, 1906. Serial No. 298,469.

5 York, in the county of New York and State of New York, have invented certain new and useful Improvements in Type-Writing Ma-. chines, of which the following is a specification. i

.My invention relates more especially to the ribbon mechanism of typewriting ma chines.

Stated generally, the ain object of the invention. is to provide simple and efficient means whereby any of aplurality of inking surfaces having different characteristics may be brought to position to cooperate with the types.

Other objects of the invention will appear hereinafter.

In carrying out my invention 1 provide a ribbon carrier or guide .which is located between the ribbon spools and through which the ribbon passes in such away as to present fed back and forth between the ribbon spools the type impressions will describe a path longitudinal of the ribbon and along'one ortion of the width of the ribbon. The rib on' carrier or guide is so constructed that it may be reversed or turned when desired, so as to present the other side or face of the-ribbon to the types, and when the carrier has been thus reversed the type impressions will describe a path longitudinal of the ribbon and along another and different portion of its width during the operation of the machine. It will readily be understood that if the ribbon is dividcd into longitudinal stripes having differ: ent characteristics, as for example different colors, one color will be operated on by the types when one side or face of the ribbon is presentedcto them and another color Wlll be operated on by the typeswhcn the opposite side or face of the ribbon is presented to In the preferredembodiment of my invention illustrated herein-I have shown a ribbon carrier or guide applied to a front-strike type- .xwriting machine, said carrier or guide normall".; maintaining the ribbon away from the pringfiig and being combined with nally of the ribbon.

one side of the ribbon for cooperation with the type faces, and so that as the ribbon is carrier or vibrator.

means for giving it a reciprocatory movement to and from the printing point during printing operations. This type -'of ribbon carrier 1s commonly called a ribbon vibrator. In. front-strike writing machines having a ribbon vibrator the ribbon which is employed is usually quite narrow and in many styles of front-strike typewriting machines said ribbon is fed back and forth. in only one direction, that is longitudinally, so that the ty )e im ressions describe a single line longitu i- My invention provides a ready means for causing the type impressions to describe a plurality of paths longitudinal of the ribbon, thereby exhausting the ribbon surface more uniformly and thoroughly. It will be understood that this latter advantage is applicable to a ribbon which is of uniform character throughout, although I have shown in the drawings a ribbon having a plurality of fields or longitudinal stripes of different characteristics or colors commonly called a polychrome ribbon, and my invention is especially advantageous when employed in connection with such a ribbon.

To the above and other ends which will subsequently appear, my invention consists in the features of construction, combinations of devices and arrangements of parts hereinafter fully described and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a vertical longitudinal sectional view, taken about centrally, of so much of a typewriting machine as is necessary to a clear understanding of my invention. Fig. 2 is an enlarged side elevation of the ribbon carrier or vibrator and a part of its supporting bracket. Fig. 3 is a fragmentary front elevation of the machine.

'Pivoted at 4 in the rear of the base are key lev'e'rs' 5, each key leverbeing provided with a restoring s ring 6. Each key lever is connected by a lin 7 with -a sub-lever 8 pivoted at. 9 in a hanger 10, said sub-lever being connected by a link- 11 .with a type'bar 12, pivoted at 13 in .a hanger 14 Secured by a screw 15 to a stationary support 16.- "The typebars are segmentally arrangedand are normally supported at their free-ends by a stationary segmental type rest 17, and are ada ted to 006 erate with the front face of a cy indrical pl aten 18. Said platen is diagrammatically illustrated herein, but it is to be understood that it is suitably mounted in a platen carrier (not shown) which is adapted to be moved back and forth across the top plate during the o' eration of themachine, said platen carrier eing connected by a strip 19 with a spring drum 20 which tends constantly to draw the platen l8 and platen leftward movement of the platen is controlled by suitable escapement devices (not shown) which have connections including depending rods 21 (Fig. 3) with a universal chine beneath the series of key levers. The universal bar is adapted to be actuated by tions to cause the escapement devices to cooperate to permit the platen to move a letter top plate. The features above referred to and not illustrated are common in the art and will be understood without further description. The general framework of the machine and the type actuating mechanism herein illustrated and briefly described above are not claimed herein as they are the invention of Oscar Woodward.

.- Ribbon spools 23 arranged vertically beneath the to plate 3, one at each side of the machine an forward of the platen, are provided with a ribbon 24 which is wound upon said spools and has its ends secured thereto. As herein shown the ribbon 24 is divided longitudinally into fields a and b of different characteristics; that is to say, the field a may be of one color, such as black, and thefield b may be of another and difierent color, such as red, or the field a may be copying ribbon and the field I) record ribbon, for example. The ribbon 24 may be fed lon itudinally from either spool to the other y any suitable .ineans, one such ineans being shown in the drawin s. Eachribbon spool 23 is secured on the orward end of a horizontally disposed shaft 25, said shaft being journaled in lugs 26 and 27 depending from the top plate 3. The rear end of the shaft 25 is provided with a beveled pinion 28 (Figs. 1 and 4), which is adapted to mesh with a beveled pinion 29 secured on a rotary driving shaft 30, the latter extending from side to side of the machine beneath the top plate and being journaled in lugs31 depending from the under side of said top late. Rotary movement is transmitted to-t e driving shaft 30 by beveled .pinions 32 and 33, the pinion 32 being opcratively connected with the driving shaft and the inion 33 with the carriage spring drum 20. t will be understood that both ribbon spools are providedwithsimilar gear trains which are adapted to be' actuated from driving pinions 29 on the driving .shaft 30; The driving shaft 30 is ada tedto be moved to and fro endwisemanna y or by any suitable auto- -matic means without displacing the pinion 32 from mesh with its 006 erating plnlon 33 by reason of-the pin and s ot connection 33 between the shaft 30 and the pinion 32; and it will be further understood that the longitudinal osition of said shaft determines which driving pinion 29 will be in mesh with its cooperating pinion 28 and which ribbon spool will be turned to wind the ribbon thereon.

Midway between the ribbon spools, the ribbon is threaded through a vertically disposed ribbon carrier or vibrator which is arranged between the ribbon spools and the platen. I have illustrated my improved vibrator as comprising two parts, a ribbon guide part 34 and a vibratory holding or su 4 porting part 35 upon which the ribbon gui 0 part is mounted, these parts being best 1llustrated in Eigs. 8 and 9. The uide .part or plate 34 is preferably formed 0 sheet metal, the body portion 36 being cut away in the center, as mdicated' at 3?. Arms 38 and 39 are formed at each side'of the body portion of the uide plate, said arms. being first bent forwar lly from the face of the body portion and thence inwardly towa'rds the middle of the guide plate. The arms are thereby given an angled form, one part of each arm 38 extending at right an les to the body portion, said part being indicated by the reference character 38 and the other part extending inwardly parallel to the body portion, the latter part being indicated by the reference character 38 The corresponding parts of each arm 39 are indicated by the- reference characters 39 and 39 The companion arms at each side have their portions38 and 39 flush with each other, said portions terminating in diagonal edges 38 and 39, said edges bein slightly separated and thereby formin a iagonal slot 40 which is designed I 50 cnnlined between the 55 hook-like portion 56 .longitur-linally of the portions 38* and 39 of i ing member or trunnion plate 47, the base 48 of said trunnion plate extending normally beneath. the guide part 34, and the arms 49 of said trunnion plate extending upwardly at either side of said guide part 34, said arms 49 2o terminating in enlarged perforated ends 50 which serve as the bearings for the trunnions 43. The guide part 34 of the vibratory ribbon carrier is supported, through the connecting member 47, on the-holding part 35' of said carrier or vibrator, which holding part 35, as shown in Fig. '8, comprises a body portion 51 and a stem 52extending rearwardly and downwardly from said body portion. The holder 35 is preferably formed of asingle piece of sheet metal. The upper portion of the body 51 is provided with a type opening 53. Beneath said type opening and extending longitudinally of the body'is a-guide slot 54, the upper portions of the sideswhereof are curled or bent rearwardly to provide bev eled edges 55. 'Extendingj 'upwardly and" outwardly from the lower end of said guide slot is a spring tongue 56, the upper end of -avhich is'ho'oked or bent rearwardly, as indi- 40 catcd at 56". At either side of'the spring tongue 56, the metal of the body 51 is cut and pressed outwardly and above these ugs 57 the metal is pressed rearwardly to provide elongated contacts or trarleways I As will be understood from a consideration of Figs. 1, 2, 3 and 6, the base 48 of the'connecting member 47 rests on thesupporting lugs 57 of the holding part '35, said base bein face of the body 51 and the sprihgfionguew, which tongue normally connecting member 47 and presses the the guide part 34, against the through it holding part 35 of the ribbon carrier.

of the spring tongue prevents the accidental withdrawal of the member 47 from its place between the spring tongue 56 and the face of the body 51. The stem 52 of the holding part 35 is bifurcated to form depending arms 52'which are curled as indicated at 52 to receive a cross-pin 59 which is engaged by one of the members of the actuating mechanism, presently to be described.

The ribbon carrier or vibrator is supported best shown in Fig. 5, the flattened inner The left-hand trunnion to form supporting lugs57 v The on a bracket 60 which, as shown clearly in Fig. 7, is preferably U-shaped, comprising arms 61 jointed at the top by a connecting web 62. The arms 61 are curved first rearwardly from the web 62 and then forwardly and terminate at the bottom in laterally projecting cars 63 perforated at 64 to receive securing screws 65 which screw into threaded openings in the back of the type bar support 16 at each side of the middle of said support,

as clearly shown in Fig. 3. The upper portion of the web 62 has secured in it a guide screw 66 which projects forwardly through the guide slot 54 in the holding part 35 of the vibrator. The beveled ed es 55 of said guide slot engage the beveFed head of the screw 66 and the track-ways 58 contact with the face of the web 62 of the bracket, thereby serving to guide and control the vibrator as it is reciprocated up and down between the arms. 61 of the latter, the track-ways 58 sliding up and down on the front face of the web 62 of said bracket.

Referring now to the vibrator actuating mechanism, this is best shown in Figs. 1, 3

and-4; The sides 61 of the bracket 60 are formed with holes 67 which receive a crossrod 68 which serves as a pivot for a bell crank lever 69, the forwardly projecting arm '69 whereof engages the cross-pin 59 at the lower end of the vibrator. The ell crank lever69 is disposed midway of the length of the cross rod 68, said rod being provided with sleeves 70 (Fig. 4) at either side of the lever 69 to revent lateral displacement of the latter.

he downwardly projecting arm 69' of the lever 69 is pivotally connected at71 to a rearwardly extending link 72, the rear end of said link being pivotally connected at 73 with the upwardly extending arm 74 of a b ell' crank lever 75. The bell crank lever 7,5 is formed with a hub 76 (Fig. 3), which hub surrounds a stationary pivot rod 77 extending from side to side 0 the machine and having its ends secured in lu s 78 projecting upwardly from the sides of t e base '1. Collars 79 'are secured to the rod 77 at either side of the bell crank lever 75, said collars preventing lateral displacement of said lever. The forward end of the horizontally disposed arm of the bell crank lever 75 is adjustably connected by a downwardly extending wire rod 80 with the universalbar 22. As indicated in Fig. 3, the upper edge of the ribbon lies normally below the printing point, said ribbon being adapted, through the above describedcon nections, to be moved upwardly to cover the printing point with its upper portion when a ke lever is operated to depress the universa bar.

For conveniently reversing or; turning the ribbon guide part 34 of the vibrator, I provide a crank rod 81- (Figsl3 and. 4). The inner end of thecrank rod is bifurcated to em:

brace the flat extension 45 of the left-hand 25 is substantially comcldent with the longitu- I trunnion 43 and is pivotally connected there- The outer or left-hand end portion of the guide rod 81 passes through an opening 84 in a guide bracket 85, said bracket bein secured to thetop plate by a screw 86. T e outer end of the crank rod .81 is provided with a cra arm 87 terminating in a'handle or finger piece 88 which may be turned to manipulate the ,rod and reverse the guide part of "the vibrator. During the vibratory movements of the ribbon carrier, the crank rod 81 will move up and down witlrsaidcarrier, the bearing opening 84 in the bracket 85 being enlarged as indlcated in Fig.4 to permit of the free vibration of said crank arm.

From an inspection of Fi s. 3 and 9 it will be observed that the pivota center on which the ribbon guide 34 turns (the trunnions 43) dinal axis of the ribbon where it passes through the guide and that therefore the edge of the ribbon which is uppermost bears the same relation to the vibrator and to the printingline whether the printing field a or b is n use.

Referring now to the operation of the devices hereinbefore explained and assuming that it is desired to emplo a two-color ribbon, as illustrated in the awings, said ribbon is wound upon the spools in the usual manner and is then threaded the guide part 34 of the carrier oravibrator. In order to properl thread'the ribbon, its lower edge is first p ed down behind the'upper prong portions 39 of the upwardlyextending arms 39, and after the upper ed e of said ribbon has passed by 13hr points or Towerfree ends of the ortions 38 it is backed up or straightene behind thefdo'wnwardl projecting portions 38 of the arms 38. y this operation it'will be noted the ribbon has been passed throughthe diagonal slots 39 and arranged in the vertically disposed slots 41. In this position the printing portion of the ribbon,

I or that portion in the guide, is, as will be understood from an inspection of Figs. 1, 3

, and 4, vertically disposed in front of the platen and with the upper edge normally maintained just below the printing line. The ribbon as it leaves the spools and extends towards the vibrator is horizontally displosed, so that between the vibrator and eac spool it is given a quarter turn or twist, as indicated at 89 (Fig. 1). In mounting the ribbon on the spools and in threading it in place, it is preferable to arrange the ribbon as shown in the drawings with the black half or stripe a of the ribbon towards the rear of the spools and that portion of the ribbon in the vibrator with the field a at the top or nearer the rinting point than the fieldb or red field. t will be observed, from an inspection of Fig. 3, that the ribbon passes in front of the body ortion of the guide part 34 and in front of t 1e upper ends of the arms 49 of the trunnion plate. If now the printing keyssbe operated, their associate type bars will be operated to cause the types to cooperate with said laten through the printing opening 53 in t e vibrator. are so proportioned and arranged that at each key depression, before the associate type bar reaches the platen, the ribbon-vibrator, through the connections comprising the bell crank 69, link 72, bell .crank 75, rod 80 and universal bar 22 will be moved upward to inter ose the u per portion or field a of the ribbon etween the type and the paper on the laten. The throw or upward movement 0 the vibrator is unvarying. Consequently as the spring drum 20 moves intermittently under the control of the escapcment devices to feedrthe platen a letter space distance at a time, and as the ribbon is thereby caused to be fed longitudinally from spool to spool through the train of mechanism coinprismg the pinion 33 connected with said spring drum, the pinion 32, a pinion 29 and a pinion 28, the type impressions will describe a strai ht path longitudinal of the field a of the rlbbon.

When it is desired to employ the lower or red field b of the ribbon, the crank handle 88 is pressed rearwardly to rotate the crank rod 8'1 through half a revolution. As the crank rod is turned rearwardly, the lower portion of the guide part 34 is swung away from the face of the supporting part 35 of the vibrator, carrying with it the trunnion plate 47 which will be swung about the upper edges of the lugs 57 as ivots and will press the spring tongue 56 iorwardly. As the lower portion of the part 34 is swung forwardly away from the part 35 the upper portion of said part 34 will slide down over the face of the part 35, being maintained in contact with said face by the pressure of the spring tongue 56/ An intermediate position of the parts is represented in full lines in Fig. 2 of the draw lngs. inspection of said figure-that on the completion of the half revolution of the crank rod 81, the art 34 of the vibrator will have assumed t 1e position shown in the dotted lines in said Fig. 2, with the outer faces of the arms 38 and 3!) pressed against the front of the part 35 by the spring tongue 56 acting through the trunnion plate 47, while the normal rearmost face of the body portion It will be clearly understood from an The parts behind the upper ends of the arms 49 of the trunnion plate as well as behind the inner end of the crank arm 81. It will be understood that the ofi-set portion 83 of said crank reversely and that part of theribbonin the vibrator will also havebeen reversed so that the stri e b will now be uppermost and nearer the printing point, while the stripe a will be lowermost, that side or face of the ribbon which previously faced the paper and was pressed against it under the action of the types being now outermost and in viewof the operator, while that side or face which was then outermost now faces the paper. Consequently as the printing in- ;strumentalities are operated as hereinbefore explained, the ribbon vibrator will be reciprocated back and forth tobring the field b in operative position and the type impressions will describe a path longitudinal ofsaid field b. When it is desired to again employ the black field a of the ribbon, the operation above described may be reversed and the part 34 of the vibrator may be turned back to normal position. The term normal position as applied to the part 34 has been used for convenience as applying to the position of said part first described, as illustrated in Figs. 1 and 2. v 7

Although my reversible ribbon carrier or vibrator'is particularly Well adapted for use with a polychrome ribbon it is not limited to" such use, and as I have heretofore stated, it may be advantageously employed in connection with a ribbon having uniform characteristics throughout in order to more thoroughly exhaust the inking surface of the ribbon than has been possible with such ribbon vibrators as have been heretofore employedhaving a uniform and unvarying viratory movement or throw. Whether the ribbon be a polychrome ribbon or a ribbon having uniform characteristics throughout, it will be understood that in one position the vibrator moves the ribbon so that one side of one longitudinal portion of the width of said ribbon will be caused to cooperate with the printing instrumentalities, and when said vibrator is reversed or turned the other" side of said ribbon will cooperate with said printing instrumentalities along another and different longitudinal portion of the ribbon. The normal positionof that part of the ribbon within the vibrator is'the same before.

i and after said vibrator has been reversed;

that is, the edge of the ribbon whichis up-,-. permost is always in the same relationtnore I mally with the printing point on the platen. It will be seen, therefore, that I provide means for. adjusting the ribbon vibrator to enable different portions of the width of the ribbon to cooperate with the printing instrumentalities without altering the Widthwise relation of the ribbon with the printing line, and that though said vibrator is moved an unvarying distance and always brings the upper portion of the width of the ribbon to the printing position, yet by my invention I provide means for adjusting said vibrator so that both the upper and lower portions of the width of the ribbon may be used and the inking surface thereby uniformly exhausted.

- Various changes may be made in the construction of the parts to adapt them to other structures or for simplifying or otherwise modifying the constructions herein shown and described, and the parts may be arranged and combined otherwise than as herein shown, all without departing from the spirit and scope of my invention.
