Ton/ll whom it majconcern:

' Be it known that I, J'Acon FELBE'L, .a citi' ,zen of the United States and a .resident of the borough of Manhattan, city of New York,

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

My present invention relates to .ribbonmechanism for-type-writing machines.

In visible-writingmachinesj a ribbonvibrator is automatically moved to and from the printing-point at; each printingopera tron.

IThe principalobject of my present invention-is to-provide a construction wherein a multicolor ribbon or; ribbon having fields of chine with a n other field'ofthe ribbon at the printing-point. :When the parts are set in the latter manner, the; vibrator acts as a mere ribbon-guide without,- however, materially affecting the visible=writing feature of the machine: a

To the above and. other ends, which 'will hereinafter appear, my inyentionponsists in the novelfeaturesof construction, "arrangements of parts, and combinations'of devices to be heremafter'fully described, and particu- 7 larly pointed out theappended claims.

machine, from which corner-posts 2 extend,

and the corner-posts are surmounted by atop1plate3. Key-levers 4.are fulcrumed at their rear ends on afulcrurn-plate 5 and. are

' each" provided with a iin'ger-keyfi and a re- 'storing-spring 4?.

Each key-lever has a suplever 7 pivoted thereto at 8, the lower end portion of said sublever, beingslotted at 9 for the reception of and cooperation with a fulcrum bar or rod 10, that extends beneath chine.

- The upper end of each .sublever is pivoted I at 1-1 to a link '12, which in-turn is pivoted at-v .its forward end 13 to-a type-bar 14. The

type-bars are-segmentally arranged andare pivotedon a pivot-wire v15 and operate in slots 16 in atype-bar se ment 17. The typebars are thus arrange to move upwar ly and rearwardly'to cooperate with. a platen 1 8, that is carried by a carriage 19, support ed by antifriction balls 20, received in grooved rails 21 on the carriage and in oppositely-grooved rails 22, secured to the top pla-teof the machine.

v The carriage is provided with a feed-rack 23, thatmeshes with a feed-pinion 24, operativelyl connected in the usual manner to an carried by a dog-rocker 27 and cooperate with the escapement-wheel. The dog-rocker '66 the key-levers from side to'side of the I na-- "escapement wheel 25. Feed-dogs :26, are

has a rock-shaft 28 that ismounted in-a suitable bracket 2-9, secured to the top plate. .A forwardly-extending arm 30 projects from the rock-shaft of the dog-rockerand is'connected at its forward end to a depending link -31, the lower end of which is connected to a rearwardly-extending. arm. 32, that projects from a frame 33, pivoted to the base-of the machine at 34. The frame 33 carriesau'niver salf bar 35, that extends beneath the various key-levers 4 and the spacing-levers. (Not shown.)

Arestoring-spring 36 is connected at one.

end to the rock-shaft of the dog-rocker, and

of which is provided with a laterally-extendingpin 39, that projects into a slot or elon-' gated opening 40in a link ,41. The upper In the drawings; '1. indicates the base ofthe wardly from the top plate of the machine.

The'ribbon 53 is divided longitudinally'into difi'erentfields a and b, which are of difierent characteristicsthat is to say, the field a -may be of one color, such as black, for instance, and the vfield b may be of. a contrast ing color, such as red, for instance, or the field cumayrbe copying-ribbon and the field '1).

record-ribbon.

'lThe ribbon may be fed longitudinally from one spool to another by any suitable means. In the present instance I have illustrated .a ribbon-feed mechanism similar to that employed in the Monarch machine; and which is shown in' United States patent: to Jacob Felbel and Carl Gabrielson, No.

In the presmeans for imparting a transverse feed to the ribbon, as shown in said patent. A beveled gear 55 is secured to a shaft-55, which rotates in a bearing 56 and has one of the ribbon-spools 54 connected thereto. The gear 55 meshes with a beveledpinion 56, secured to ashaft 57, which carries a beveled pinion 58, that is adapted tomesh with a beveled driving-pinion (not shown) on a shaft 59, this shaft being capable of a longitudinal as well as a. rotary movement. Rotary movement is transmitted tothe 'shaft'by beveled pinions 60 and 61, the-pinion 60 being operatively connected to the shaft and the pinion 61' operatively connected to a springclrum 62,which draws the carriage across the machine. It will be understood that. both spools are provided withsimilar gear-trains which are adapted to be drivenfr'om driving pinions on the shaft 59 and that the longitudinal disposition of said shaft determines whichdrivingepinion will be in mesh with its cooperating gear 58, and which ribbon-spool will'be turned-to wind the ribbon thereon,

. A'rock-shaft'63 is mounted in bearings 64, which depend from the top plate of. the machine, and the inner end of this rock-shaft is provided with a crank-fingeri65, that is positioned at a point where it is adapted to cooperate with the rear end portion of the ribbon-vibratoractuating lever 43 The opposite end of the rock-shaft extends beyond the top plate of the machine and is provided with a finger-piece 66, by means of which the rock-shaft 63 may be turned to'either one of two positions. -A'stoppin 67 is arranged in the path of the finger-piece 66, so as to limit the downward movement of the finger-piece, and thus regulate the movement of-the rockshaft in one direction. When the fin erpiece has been turned up to the position il ustrated in Figs. 1 and 2, the crank-arm or finger 65 is turned up to a position where it. does not interferexwiththe operation of the actuating-leveri43. -When, however, the-fin er'-- "piece is turned down to 'the'position' i ustrated in Fig. 3', the'rear endof the actuating 'lever will be depressed and the folward endof the-lever and the'ribboneguide 50 will be elevated, so as to bring the field'bgof the rib bon' to the prirniing point. The 'link 41 is moved down against the tension of the spring 46 to'a,position'where the-pin 39 will normally'be seated'in the'upper instead ofthe" lower-endof the slot 40. Theconst-ruction against the stop-pin 67 the arm 65 is ator a little past the dead-center, soJthat-t'he parts will remainin thisposition untiltheyar'e restored'by-hand.

a is. such that when-the finger-piece 66 lies.

From the foregoing description 'the opera tion of the machine WillFbe understood. When thefinger-piece-66 and .its associated parts'are in their normal positions, as-represented in Fig. '1, the depression of a "key lever-will effect an actuation-ofa type-bar to move it upwardly and rearwardly to' the. printin -point;and will also depress the 'universal ar 35, which, through the intermediate connections between the-'lever. and=uni-' 'versal bar, will carry down the 'rear end of the actuating lever 43. The effe'ctlof this movement is to-elevate the-ribbon-vibrator automaticall so as to bring the field'a of the ribbon into t e path-of "the type as the type roe;

bar approaches theprinting position. When i the finger-key is released, "the "key-lever will 'be restored to'its normal position, and spring 36 'of the-esca ement mechanism will restore the universal ar and 'the link 38 to their normal positions, and the spring 46 will return the link 41, the actuating-leverf43, and the ribbon-vibrator to their normal positions. When, however, thefinger-piecfifi'standsin the position'illustrated inFigj3, the ribbonvibrator is maintained in the raised'position, where thefield b of'the 'ribbon is in the path of the types on the t e-bars and'thep1n39 stands normally at the to of the slot.40. An actuation of the .fingen eys at this time merely resultsm moving the pm 39 down and up in its slot 40 without transmitting any movement to the link 41, the actuating-lever 43 or the ribbon-vibrator.

From vthe foregoing description it will be understood that when the parts are set to afford an actuation of the vibrator at each rig Ieo

' maintains the ribbon away from the. print ing-point to expose the printing'point or line (indicated by the dotted line xfto the view of the operator, Whereas the act of setting the pa'rts by the harid-actuated finger-piece 66,-

.so that the vibrator remains at rest during- -the actuation of the machine, is efiectixe to move the vibrator to andmaintain it in a position where the field b of the ribbon will cover the printing-point or be interposed be- I tween the types and the printing-point that the vibrator is' adapted to be operatively connected to its actuating means or'to be thrown out of operative connection therewith; that one printing-field of'the ribbon is employed of the ribbon to coverthe printing-point at printing operation, and that when the virator is disconnected from its actuating means it causes another field oft'he ribbon to cover the printing-point and to be maintained fixedagainst movement, but that it does. not

materially affect the visible feature of the machine, since the ribbon slants llown fromthe vibrator to the ribbon-spools and exposes the writing on either side of the virator; that the ribbon-vibrator' is adapted :to move with orfindependently of'its actuat;

ingmeansvin orderthat one or another field of the ribbon may be employed; that means "are employed for throwing the connections between the ribbon-vibrator and its actuating means into and out of cooperative relation,'and that in one case the finger-keys are effective to; transmit movement to the vibrator through said connections to bring one field of the ribbon to the printing-point and in another ca se they. are inefiectivefor this purpose and another field of the ribbon is maintainedat the printing-point that when the vibrator is -maintained at rest thefinge'rkeys, type-bars, and escapement mechanism may be moved" independently thereof, and that the vibrator which is fixed at this time does not, therefore, interfere with'the actuation of these parts, and that in either case the ribbon will be automatically fed in the direction of its length. f

various changes may; be made without-dc:

parting from the" spirit of my invention, which, from certain aspectscontemplates,

broadly, the provision of. means which may be regulated at will to afiord an automatic movement of the ribbon transversely of the platen to cover and uncover thev printingf point and to bring one field of the ribbon to the inting-point or to aflord a maintenance oft e ribbon fixed against such transverse movement during the actuation, of the ma'- 1 chine in order that another field of the'rib bon maybe positioned at the printing-point.

move the ribbon.

It is to be understood, that a ribbon of uni-'- -for n1 character may be einployed'with the invention, which will enable the ribbon to be used lengthwise in a plurality of fields o1" lines, thereby tending to' "more thoroughly and evenly exhaust the inked surface.
