all whom it may cancer-'74 Be it known that l, BURNIIAM C. Sricir- NEY, a. citizen ofthe United States, residing in Elizabeth, in the county of Union and State of New Jersey, have invented certain new and useful Improvements in Type-Writint Machines, of whichthe lollow ng 1s a spcclfication.

This invention relates to the ribbon inech-,

anisin of typ'ewriting machines, particularly those in which the ribbon is vibrated to cover and uncover the printing strokes. I

. The object of the invention is to provide practical means for enabling the printing of any one of three or more color at will, as well for enablingthe types to strike the platen independently of any ribbon for writing stencils.

i'vlvinvcntion is illustrated in connection point at the type with two ribbons and two vibrators, one for Both ribbons are rcctly by a single or a unipartite 'LlDIVGTSSl each ribbon whereby either ribbon may be caused to cover and uncover the printing point at the type strokes. A winding mechanism is provided which can be connected to either pair of. spools, at will or can be held in annidway position out of connection with both pairs of spools; and means are also provided for calling into action that vibrator Whichcarries the ribbon that is winding.

preferably operated dibar, and l contrive to cause said universal bar to sheet variablevibration cl each of the ribbons so as to cause different widthwisc portions thereof to cover the printing point,

at the will of the operator. Preterably' a single linger-piece controls the shiftingof the ribbon vibrating lIltfGllitlh ism as well as the sl'iifting ol the spool winding mechanism; suitable means vided lor varyingthc widthwise throw of either ribbon without effecting its winding mechanism. V 7

In the accompanying drawings, in which my iniproveu'ients are shown applied to'the well known lli'iderwood front strike writing marhme, Figure l .the ribbon mechanism, showing the lront ribbon ele ated to cover theprinting point, and showing the spools which carry said ribbou connected to' the winding mechanism. Fig. 2 is a plan of parts seen at-Fig. 1. 7 Figs.

being pro is a rear elevation oi"- I 3, 4, 5,6 and 7 illustrate in plan the manner of variably operating the different vibrators, Fig. showing the arrangement when neither vibrator is operated at the type strokes. Fig. 8 is a sectional side elevation of parts seen at Fig. 1. Fig. 9 is front elevation of an index, and a color plate or scale for enabling the operator to adjust the mechanism for printing any one of four colors or for enabling the types to print independently of the ribbons.

Upon the front side of a platen'l strike types 2, carried upon type bars and adapted to strike through either a front ribbon 4 o a rear ribbon 5, which are of dii'lercnt colors or qualities. The front ribbon 4 is wound upona pairof spools 6, 7 mounted at oppo site sides of the printing point and in front of the platen, with their edges to the latter and contained in a pair of cups 8, 9. The ribbon which extends between these-spools is threaded through a vibrator 10 standing in. front of the platen. The rear ribbon 5 is wound upon a pair of spools 11, 12, carried in cups 13, 14 and threaded through a vibrator 15, which is mounted. between the vibrator 10 and the plate-In It will be seen that the pair of spools 6', 7, is between the spools 11, 12, so that two spools lie edge to edge upon each side of the printing point; the rear ribbon 5 extending in rear of the cups 8, 9.

' In said Underwood machines, heels provided upon the type 'bars press rearwardly a curved universal bar 16, whicl'i is fixed upon the frrmt r-irrl ei a.fraine or table 17, the latter carried at its rear-end upon upright rock-arms 1S pivoted at 19 and operating a slotted arm 20. pin 2 I of a crank 22 lixed upon a rock-shaft 23, the latter having each side of the ma- "chine an. arm 24' carrying a pawl 25 to engage a. ratchet wheel 26 for winding the ribbon. In said machine a shifter bar 27 throws one pawl 25 into action as at the left hand side of Fig. i, and the other pawl 25 out olaetion at the right hand side of said Lilli'lli'l' is r versing, the longitudinal travel of the ribbon. ,By means oi? said pawl and ratchet mechanism, there is rotated at each. side of the ma chine a pair of mitrc gears 28, 29, the gears 29 lixed upon the lower ends of vertical shal'ts 30, 31, which. at their upper ends carry gears 32, 33. The gear 32 isunounted the winding gear 32 is being driven by the pawl and is in mesh with iIhe gear 35 to wind the ribbon i on the spool {5; while the gear 33 in mesh with 38 turns idly during the 10 delivery of the ribbon from the spool 7; said gear 33 being disconnected from its pawl 25.

Various means may be adopted lor cilecting relative shii ting movementsbetween the Winding gears 32, 33, and the two pairs oi spool gears.

fire vibrated towards and vfrom each. other to ell ect shifting of the winding gears. Such movement is eliccted by means of a fingerpiece 47 rovided upon an arm or lever 49, 'Which. is mad upon a rock-shaft 50 extending rearwardly and having upon its rear end a" crank 51 which at the operation of said .arm ,49 is caused to vibrate. Said crank 51 has a in or Wrist 51 to engage a slot 51. formed --'in a bar 52, which'extends across themachine and is guided by studs 53L Sai d bar 52 3 has an arm 54, through which. passes. the vertieal winding gear shaft 30, so that the vibration of said arm 51 c-aiises the sl'iifting 'of said Winding gear between. the spool gears 34 and '35. The other end of the shifter bar 52 is pivoted. at 55 to one end of a lever 56 The winding gear shaft 31 passes through the front end of said lever, which is pivoted mid way between its ends at 58 upon the framework. By this'incans the shafts 30, 31 togctherwith theirgears 32, 33 are caused to move elther towards each other or away from each other to mesh with either pair of spool gears. YVhcn the parts are at the other extreme from that s.;en in the figures, the outer spools li'anii are connected to the wind platen supporting rail 67 of the jUnder- That illustrated is in the 1121- ture ol a contrivance, whereby the winding wood. machine, so that the levers together with the vibrators are shifted up and down at the platen shitting movements of said inachinc. Said levers are operated by nieansot a, pair of upstanding levers 68 and 6.), pivoted at their lower ends at 70, upon some fixed portion of the machine and having at their upper ends vertical slots 71 and. 72 to engage pins 73 and 74, provided upon upstandmg arms 75 and 76 oi'the levers '63 and 64 said slots accomodatnig the up and down movements oi the levers atthe case-shift operation. By vibrating either lever 68 or 60, its associated lever63 or 64 is caused to throw up its attached ribbon vibrator 1.0 or 15. Thcsclevers 68, 69 are actuated by the universal bar frame 17, but only one lever can be actuated at a time; said frame carrying a slide or interponent 77 guided by studs 765 and having a too 79 to engage either lever (58 or 69 according to the adjustment ot the slide. At Figs. 3 and 4 said too is shown in position to eng:ge the lever'68. At Fig. 5 it is shown in such position. that it will pass idly between said leverp at thetype strokes, wher by both ribbon vibrators are silenced. At Figs. 6 and 7 the tee is shown in position to engage the lever 691 One engages either lever, the other lever stands idle so that only one vibrator at a. time is called into action.

At-Fig. 4 a full stroke is given to the lever 68 andto the ribbon vibrator 15, so that the lower border or color band of the ribbon is lifted to covertheprinting point,

each ribbon having preferably two color bands, one extending along each edge in a well known manner. ponent 77 is in the Fig. 3 position, the lever 68 stands beside a cutaway-or shoulder '80 formed upon thetoc, whereby a minimum motion is given to the lever 68 and {the vibrator 15, so that the upper color band of the ribhonS is brought up to cover the printing point.

At Fig' 6 the interponent is illlustrated as giving levers 69 and ribbon 4 amaximum stroke to cause the lower border of the ribbon to cover the printing point. At Fig. 7 the opposite side of the tee is seen recessed at 8] to engage the lever '69, to give the'latter a minimum stroke and cause the upper portion or color band of the ribbon4 to-cover the printing point. The shifting of said slide or interponcnt 77, is etl'eeted by a vertical pin 82, extending up fronia fork 83 in said. slide to a bar 84, supported upon the frame-work and extending across the machine, and

When the too or interguided for a longitudinal' movement upon I the positions indicatedrespectively at '3, 4, 5, and The bar.84 is adjusted by means of the rack 93 thereon, in mesh means for enabling said universal bar to viwith, a pinion 94 provided upon the shaft 50, so that'the single finger-piece 47 will simultaneously bring either ribbon vibrator into action, and, cause its associated spools to Wind. The interponent or toe 79 will oper atethat lever 68 or 69which controls the vibrator carrying the ribbon which is wound upon the active spools. The fork 83 accomodates. backward and. forward movements of the interponent 79 at the operation of the universal bar frame.

68-and 69 to restore thel after actuation. I

1 When the interponent 791s at the Fig. 5

position, the bar 52 is held in a midway posito normal position tion, and-the detent 87 rests in the middle notch 90.. At this time-the pinions 32 and 33 stand in midway positions out of Contact with the pinions 34, 35, 38, 39, so that both the \vindingmeans and the vibrators are silenced.

While the finger piece 47 is being turned to move the interponent 79 from the Fig. 5 po- .sition .to the Fig, 4 or Fig. 6 position, the crank 51 gives the bar 52a full stroke in the corresponding direction; but while said "linger-pieceais swinging to move the bars from .Fig. 6 to the Fig the Figh 4' to the Fig. 3 position, or from the .]7 position, said bar 52 remains motionless, the pin51 traveling idly up along curves 96, formedin the slot 51 concentrically with the rockashaft '50.
