Specification of Letters Patent.

Application filed June 11,1902. Serial No. 111.083.
To all whom it may concern.-
Be it known that I, WILLIAM L. CooKE, a citizen of the United States, residim at Newport News, county of l/Varwick, and State of Vir inia, have invented a certain new and useful Improvement in Ribbon Shifting Mechanism for T e-Writers, of which the following is a speci cation.
My invention relates to a new and useful improvement in ribbon-shifting mechanism for type-writers, and has for its object to provide a" mechanism to be applied to typewriters wherein either ribbons of different characteristics or colors arranged side by side are used or a ribbon having different characteristics or colored with different colors, the colors referably running longitudinally of the rib on and arranged side by side on the same, and this mechanism which I provide will enable the operator to shift from one characteristic or color to the other by the simple manipulation of a key.
With these ends in view this invention consists in the details of construction and combination of elements hereinafter set forth and then specifically designated by the claims.
In order that those skilled in the art to which this invention appertains may understand how to make and use the same, the construction and operation will now be described in detail, referring to the accom anying drawin s,forming a part of this speci cation, in whic Figure 1 represents a rear view of a Smith Premier type-writer with my improvement applied thereto; Fig. 2, a plan view of the same; Fig. 3, an end view of a Smith Premier t e-writ'er with my improvement applied tereto, showing the mechanism in position for utilizing one color ribbon; Fig. 4, a similar view toFig. 3, showing the mechanism in osition for utilizing the other color ribbon;
ig. 5,. a front elevation of my im roved pitman; Fig. o, a perspective view 0 the crank; Fi 7, about elevation of a ribbon-spool (livided so-as to accommodate two ribbons of different colors. Fig. 8 is a vertical front-torear sectional view, taken about centrally, of a type-writin machine embodying my invention, parts of the machine being omitted.
My invention is adapted particularly to the Smith Premier type-writer, but of course would be capable of use on other forms of writing-machines.
A re resents the casing containing the spring or feeding the carriage. This casin revolves around a stationary shaft B, and journaled loosely upon this shaft is a ratchetwheel C, which is engaged by a spring-pawl D, the pawl being carried by the spring-casin A. Secured to the ratchet-Wheel C is an elh tical gear E. Thus by reason of the pawl an ratchet the gear E is only revolved when the carriage is fed step by step by means of the spring, but remains stationary when the carria e is returned. Secured ri idly to the shaft at its outer end is an arm and fixed on a short shaft F, which is journaled upon the outer end of this arm, is another elliptical gear G, which is in mesh with the gear E. Se-
,cured rigidly to the same shaft as the gear G and revolving therewith is a crank-arm H, said crank-arm being formed with an opening H", Fig. 6, which fits over the rear end of the shaft F, which is snared for the pur pose. A headed screw l screws into the end of the shaft F and secures'the. member or crank-arm H in place. Pivoted to the wristpin-I-I of the crank-arm H is a 'pitman I, which is connected at its lower end to an arm J, which arm is secured rigidly to a rockshaft K, extending across the machine at the rear, so that each time the pitman I is raised and lowered by the revolving of the crank H the shaft K is rocked. Secured rigidly to the shaft K at each end are upwardly-extending arms L, which are slotted at their upper ends, and through the slot extends a pin or screw, which is connected to yokes M, embracing the ribbon-spools N. These ribbon-spools are mounted to slide u on transverse shafts O, and thus as the shaft I is rocked the ribbon will be caused to travel backward and forward laterally oi the machine, and at the end of each lateral movement of the ribbon-s ools mechanism is provided (shown in the rawings in Fig. 8 and presently to be described) which will revolve the spools sli htly, so as to wind the ribbon upon one an unwind it from the other. Thus all the surface of the ribbon is utilized in writing.
In the ordinary Smith Premier type-writer bons of different colors one-half the width ofthe ordinary ribbon and place a divider N upon the ribbon-spools, as shown in Fig. 7, to separate the ribbons. It will now be obvious that when writing withone color it will be necessary to limit the lateral movement of the ribbon-spools, so that said spools will only travel a distancebackward and forward equal to the width of one of the ribbons or one of the colors upon the ribbon, and Laocomplish this limitation of movement by reducing the distance between the center of the shaft upon which the crank H is secured and the center of the wrist-pin of the crank onehalf. Thus it will be seen that the movement imparted to the pitman I will only be onehalf of that ordinarily used, and therefore the ribbonspools will only be given one-half of the usual movement.
- The pitman I consists of a lower portion I, to which is secured and extends upward therefrom the upper spring portion I and this u per spring portion consists of one piece 0 metal secured at each end to the ortion I, so as to form a loop, the two sides of the loop being brought together and running upward parallel with one another, and at two points the metal is bent. outward in a semicircle from each side, so that the two sides will form hearings in which the crankpin of the crank H is adapted to rest. There are two of these crank-pin bearings formed in the spring portion P, the upper one represented by the letter P and the lower one by the letter P. When the crank-pin H of the crank is resting within the bearing P in the spring portion I as shown in Fig. 1, the ribbon-spools will only be caused to travel backward and forward across theforward ribbon or the color of the ribbon nearest the-front of the machine. This nosition is illustrated in Fig. 3. If it is desired to shift to the other color by pushing upward upon the pitman I, the two sides of the spring portion I would be caused to spread, and the crank-pin H will travel between these sides and spring into the bearing P, and by thus ushing upward-u on the pitman I the ribon-spool 1s shifts along the shafts 0 toward the forward end of the machine, and thenthe movement imparted to the spools by the revolving of the crank will be limited to the width of the other ribbon or the other color of the ribbon. This position is shown in Fig. 4.
For the purpose of facilitating the pressing upward of the pitman I, I secure tothe shaft crown ratchet-whee K a key-lever Q, which extends forward to a point near the key board, and by pressing downward or pulling upward upon this keylever the crank-pin can be'transferred from one to the other of the bearings P and P in the pitman I. Thus it will be seen that by the simple manipulation of the key-lever the ribbon can be changed from one color to the other and by the addition of no more mechanism than is now in use upon the Smith Premier typewriter. I
Fig. 8 shows a central sectional view, with partsomitted, of a type-writing machine which is essentially similar to the No. 2 Smith Premier t pe-writer and to the machine illustrated in Figs. 1 to 7. In Fig. 8 a ribbon R is represented as wound upon the spool N, which is the left-hand spool in the machine, and said ribbon is shown as a multiplex ribbon, being divided lengthwise into two differently-colored stripes or fields, (indicated by the-reference characters r and 1",) it being understood that the fields may be differently colored or that they may differ in other respects than coloring. For example, the field or stripe 1* ma be rovided with copying-ink and the fiel r with record-ink. The front face of the forward flange of the spool N in Fig. 8 is shown as provided with a series of ratchet-teeth S, and cOoperatin with said ratchet-teeth is a pawl T, pivote at U to the framework of the machine,-the tooth V of said pawl en aging with the ratchet S. It is to be un erstood that the right-hand ribbon-s 001 is provided with a l similar to S and that a pawl similar to the pawl T is adapted to cooperate therewith. series of type bar hangers are circularly arranged and fixedly supported on a type-ring W, secured to the frame of the machine. Each hanger X pivotally supports a. type-bar Y, carrying at its free end a t .pe Z. A link A connects each of the typears with a rock-shaft B, the se- I ries of rock-shafts being supported in the base of the machine and extending from front to rear thereof. Each of the rockshaft's'is provided with a restoring-spring C and a finger-key D. The printmginstrumentalities just briefly described are of known construction, and it is not deemed necessaryto explain them at greater length; It will be understood that when any fingerkey D is adequatel depressed the associate rock-shaft B wil be turned in its bearwi 1 be swung upwardlyuntil t e type Zcoo crates with the under face of the platen of t e machine, said platen being diagrammatically shown in Fig. 8 and indicated by the reference character E.
Ioo

vin s, and the type-bar Y throu h the link A The'operation of the devices hitherto de- I scribed and explained may be briefly referred to. The platen E is mounted in a carriage (not shown) of suitable construction,
which is connected in a known manner with the mainspring-case A. The platen-carriage and platen are normally held from movement under the influence of the mainspring by carriage feedin devices, (not shown in the drawings,) W ich carriagefeeding devices are operated in a known manner by the oper ation of the printing instrumentalities in such wise that on the de ression of any printingkey D the carriageceding devices cooperate to permit the platen-carriage and platen E to move the distance of one letter-space in printing direction. During this step bystep feedin movement of the carriage and the platen t e motion of the mainspring case or drum A is transmitted in a manner hereinbefore explained through the train of mechanism com risin the ratchet-Wheel C, gears E and G, s aft and crank-arm H to the pitman or link I. The movement of the itman I is transmitted through the arm to the rock-shaft K and thence through the arms L and yokes or carriers M to the ribbon spools or holders N, the arm J, rock-shaft K, and arm L being, in effect, a bell-crank lever. During the upward movement of the pitman I the ribbon-spools will be moved longitudinally of their shafts or axles 0 toward the front of the machine, and during the down- Ward movement of the pitman the spools will be moved toward the rear of the machine. In other words, the up-and-down movement of the pitman causes an axial movement of the spools and a transverse reciprocator movement or crosswise feed of the inking-surfaces of the ribbon R. As the ribbon-spool N moves forwardly along .its shaft 0 the pawl-tooth V, engaging one of the teeth of the ratchet-wheel S, will communicate a rotary movement to the ratchet-wheel and also to the ribbon-spool, thereby impartin a longitudinal movement or lengthwise fee to the ribbon R, which will be gradually unwound from one of the spools and wound upon the other as said spools are moved toward the front of the machine. As the spools are moved toward the rear of the machine the pawl-tooth V will slide downwardly from one tooth to another of the,ratchet-wheel and will not affect the latter. It will be understood that the corresponding ratchet-wheel and pawl of the other ribbon-spool operate in a similar manner to impart a longitudinal movement to the ribbon and that means'are provided of a known construction for causing the alternate engagement or cooperation between the pawls and their associate ratchetwheels, so as to reverse the direction of the longitudinal feed of the ribbon. The ribbon mechanism which I have described provides means for thoroughly exhausting the inkingsurface by feeding it in two directions at angles to each other, the angle in this instance being substantially a right angle and a double feeding movement occurring simultaneously at one time, while at another time only the crosswise feed is operative. I do not desire, however, to be limited to the particular kind or style of ribbon-feeding mechanism which I have illustrated and described.
In Fig. 8 the crankin H is shown as engaged with the lower earing P of the pitman I, and the crank-arm H is shown at the limit of its u ward movement. With the parts so relate the ribbon-spool N will be in the position indicated b the full lines in Fig. 8 and by the dotted-lme position nearest the front of the machine in Fig. 4. The actuation of any type-bar Y at this time, will bring its type Z against the ribbon R near its rear ed e, and the imprint will be made consequent y from the field or zone 4', During the subsequent printin operations the crankarm H W1ll be rotate downwardl and the ribbon-spools N will be moved longitudinally of their axles 0 toward the rear of the machine, communicatin a crosswise or'transverse feed to the rib on, so that when the crank H has reached the lowest point of its downward swing the spoolswill be 1n the rearmost dotted hne position. (Indicated in Fig. 4.) The parts are so Zproportioned that in this osition the types contact with the rib on near the front edge or limit of the field or zone 1 During subsequent printing operations the ribbon-spools will a ain be moved toward the front of the machine and will be rotated at the same time, thereby communicating a longitudinal or lengthwise feed movement to the ribbon and a simultaneous crosswise feeding movement. It will be observed that with the pitman I in the de' scribed positionthat is, with the crank-pin H engaged with the lower bearing Pthe ribbon is so controlled that the only portion of the width of it which is in operative or working position is the field or surface 1*, and the contact of the types is confined or restricted to said field r, the ribbon moving over or across the printing-point on the platen within the limits defined b the front and back edges of said field r. en it is desired to write on the field or surface 1", the handoperated spring member. or pitman I is moved downwardly until its spring portion I yields sufficiently to permit the crank-pin H to disengage from the lower crank-bearing P and engage with the upper crank-bearing P. This movement of the pitman causes an axial shift of the ribbon-spools, but without changing the character or mode of operation of the automatic mechanism for communicating axial and rotary movement to the spools. With the parts related as last described the ribbon-spools as the machine is operated will be automatically reciprocated or moved fore and aft of the machine and rotated in a manner similar to that hitherto explained; but the limits of the reciprocatory movement will i now be those represented by the dotted-line tlieparts of the mechanism being so proporti'oned'and controlled that that part of the width of the ribbon which is in operative po-.
sition will have as'its limits the front and rear edges ofthe said front zone or field r.
f Of course while .I have shown and described the machine as operating with only two different .colors and while this form would probably be the most practical, it is obvious that more than two colors could be utilized, fin which case the crank H would have to' be shortenedaccprdingly and more bearing-places inserted in the spring portion I? of the pitman I. Itfis furtherobvious that ribbons or inking-surfaces having character istics differing nother respects than. color may be employed.
I f courseI do not wish to be limited to the exact construction here shown, as various modifications could be made without departin from the spirit ofmy invention.
aving thus fully described my invention, what I claim asnewand useful is 1.
