FRANZ X. WAGNER, OF NEW YORK, Y., ASSIGXOR TU UNDEHWOUD No. 848,707. Specification 0 YORK, N. Y., A (OIUORA'llOX OF NG MACHINE.

Apnllcation filed larch 27,1905- Sorial No. 252.382.

To all whom it may mmn'rm Be it known that l, Ftuxz X. Wauxntt, a citizen of the United States, residing in Bronx borough, New York city,in thccouuty of New York and State of New York, have invented certain new and useful Improvements in 'lype-Writing Machines, of which the following is a specification.

This invention relates to the ribbon-controlling dcvices of type-writing machines,,

and particularly to tltc mechanism in frontstrike and other visible-writing nut-chines by which the ribbonis caused to cover and uncover the printing-point at each type-stroke.

The object of my invention is to produce a simple and satisfactory mechanism for enablmg the operator to bring tnto use either the upper or the lower. color-band of a polvcltromatie ribbon and also to render the rtbbm1-vtbratmg'meclnnnsm ineffective dur- 5 ing the operation of the types at will, so as to adapt the machine for writing stencils for use In mimeographic work.

A further object of the invention is to provide means for enabling the operator positively and certainly to bring into use either color-band desired without the usual ne-;

eessity of first striking a type-key to ascertain what color is written thereby and withoutthe liability of making an error as to the color and also to determine at any time by a glance which color-band of the ribbon is in use or whether the ribbon-vibrating mechanism is thrown out of use.

In carrying out my invention T. provide between the ribbon-carrier of the well-known Underwood type-writ ing machine and the lever which vibrates said carrier at the keystrokes a member having steps, and I provide means for enablingsaid lever to engage either of said steps, and hence to move said ribbon up and down over the printing-point, thus bringing into use either the top colorbaud or the lower color-band of the ribbon, accordi g to the particular step which is in use. Said stepped member is )referably upon the ribbon-carrier itself. I provide upon the framework of the machine a shift erbar which can control said stepped member,

while not interfering with the .up and down movements of the ribbon carrier. The shifter-bar I operate by means of two keys,

'-f"'- l'l i l l f' -l out o w on .I. (U orru and tto ot. tcro wine 1 1 color black. The connection between the t keys and the ribbon-carrier are such that when the red key is depressed thered band of the ribbon is put into use; on the contrary, when the black key is depressed the black band is put into use. Other colors of ribbon and keys, however, maybe employed. Other objects and advantages will hereafter appear.

In the accompanying drawings, Figure 1 is a sectional side elevation taken through the ribbon mechanism of an Underwood type-writing l1ltl.,('lllllt tllltl showing my improvemcnts applied thereto. Theparts are in normal position, bttt the platen and ribbon mechanism are shown elevated to the position for enabling the capital types to print. Fig. 2 is a sectional rear view of the parts sec-t at Fig. 1. Fig. 3 is a plan of the saute. Fig. 4 is a. perspective View of the principal portions of the ribbon-vibrating mechanism,

Ethe parts being shown in the positions seen at Fig. 1. Fig. 5 is a rear view of the rlbbon- Zcarrier, but showing the parts shifted to i such a )USilltHl as to cause the lower'colorband 0' the ribbon to be brottght into use, but ol" rwise in the same position as at Fig. 2. Fig. 6 shows the parts in printing posi- 1 tion, but at the lower-case shift. Fig. 7 is a view similar to Fig. 5, but showing the parts shifted to position for causing the lower color-band of the ribbon to be brought into use.

As usual in the l'ndcrwood front-strike writirig-machine, t ype-l mrs l ,eiirrying lowercase types 2 and upper-case types 3, strike rearwardlv through a ribbon 4 against a platen 5. Said platen is usually mounted in a frame or carriage (not shownlwhich runs ttpon a rail ti, and this rail is shit'table up and down, together with the platen-frame and platen, to enable the types .2 and 3 to print. At Fig. 6 the parts are in lower-case position to enable the types '2 to print while at all the remaining figures the parts are in upper-case t position to enable the types 3-to print. At each type impression the ribbon is lirst vibrated up to cover the printing-point and i then down todisclose the writing. these movements being etl'ectcd by a carrier 7 standing vert' -al ly in front of the platen and i guided ina casting or segment in which ere also mounted the type-bars l. This ribl bon-carrier is actuated by a lever comprisl ing arms 9 and 10. The lever is pivoted at which is engaged by heels 18, formed upon the type-bars. Each type-bar as 1t swings to the platen pushes back said universal barframe, together with the slotted member 13,

'thereby vibrating the lever-arm 10 backwardly and elevating the lever-arm 9, so as to raise the ribbon-carrier 7, together with the ribbon. The return movements of said universal-bar frame are effected by a spring 19 The ribbon is formed along its upper portion with a band 20, which is charged with black ink, and along its lowe portion with a band 21, which is charged with red ink, although other contrasting colors are sometimes used. To enable either color to be used at will, I provide 'means'for enabling the lever-arm 9 to raise the ribbon-carrier to different elevations, giving the same ashort stroke when it' is desired to use the black upper band 20 and a long stroke when it is de- To this end I pivot at 22 upon the rear face of the ribbon-carrier 7 a plate 23, having'at its lower ends steps 24 and 25, with either of which said lever may cooperate, whereby strokes of ditl'erent' lengths are given to the ribbon-carrier, owing to the difference in the distance of the steps from the lever-arm 9.

' When it is desired touse the black'band 20,

the upper step 24 is brought into play by vibratingthe stepped member 23 to the right at Fig. 7, so that the initial portion of the upward stroke of the lever-arm 9 is idle, and the ribbon-earrier is lifted only during the last portion of the lever-stroke ust suilicient to cause the black band 20 to cover the printing-point. When, however, 'it is de siredto use the redlower band 21 ,the. stepped member 23 is vibrated to the left at Figs. 5

and 6, so that the lower step 25 stands opposite the lever-arm 9, and there is little or no lostmotion of the latter during its up stroke, whereby the riblmn-carrier is given a.fullupward movement until the lower red band 21 tands over the printing-point. \Vhile said te s are shown in the form of projections, stil the projections may be omitted within the z -ope of the invention. It is not necessary in al cases that the shiftable stepped member 23 he pivoted upon the ribbon-car .rier or pivoted at all or even positively attacized to a moving member.

Between thcsteps 24 and 25 is an opening 26 of sufficient width to permit the lever- :n'm f) to play freely up and down therein. When said shiftable plate 23 stands in vertical or midway position, as at Figs. 2 and 4, the lever plays idly up and down in said opening during the ty e-strokes and the rib bon is not moved at a I from its normal position. Thus the types strike off the ribbon, this provision being useful for mimeograph and other kinds of work.

For shifting the stepped member 23 to either one of its three required positions I of the machine a shifter-bar 27, having forks or slot member 28 extending down in rear of said ,late 23, said forks bestriding a. pin 29, whic 1 projects from said plate 23. The forks (or the intervening slot) stand vertica ly so as not to interfere at any time with the up and down movements of the pin 29 or the ribbon-carrier. By sliding the shifterbar 27 to the left or right the forks are caused to engage the pin 29 and vibrate the carrier to either of the three positions illustrated in the several figures. It will be seen that. the shifter-bar extends to the side of the machine, and, if desired, it may be prolonged to form a finger-piece 30, projecting at the right-hand side of the machine, convenient for the operator. Upon the bar I form three notches 31, either of which is engageable by a spring-detent 32 for detaining the shifter-bar, and hence the stepped plate 23, in either of the three positions referred to.' I prefer, however, to provide a rock-shaft 33 having an upstanding arm 34 to engage a notch 35 formed in the end of the shifterbar 27, so that by rocking said shaft the bar may be shifted. Upon the forward end of said shaftand just in front of a vertical plate 36, which stands in rear of the usual type-keys 37, I provide a two-arm lever 33, one arm carrying a red key 39 and the other carrying a black key 40. It will be seen that when the black key 40 is depressed the arm 34 is rocked to the right at Fig. 2, and consequently the stepped member 23 is swung to the Fig. 7 osition, which is the position for hringin t 1e black band of the ribbon into use. W ten the red key is depressed, the member 23 is swung to the Fig. 5 position for bringing the red bandinto use. When the keys are level or in midway positions, as seen at Figs. 2 and 4, the plate 23 stands in a ing 26 is opposite t e lever, and hence the ribbon does not move up at the ty e-strokes. The provision of the red and blue keys is a. great convenience, since the operator is enabled to tell bymerely glancing at themwhich color-band of the ribbon is in use, and at any time a. simple touch upon a key changes the color. There is no possibility of printing, the wrong color upon the paper, which has ,heretofore been a source of greatannoyance to the operator.

provide upon a fixed part 8 of the framework position where the open- The weight of the riblain-earrier assists the returnithereot to normal position; but l prefer to provide upon the bottom of the ribboncarrier at cross-pin -H beneath the end of the lever, so that the latter in its return movement may insure the return of the ribbonc-arrier. \Yhen the shift-rail and platen are elevated to enable the upper-ease types to print, the lever is carried bodily up by reason of its being pivoted upon the braeket 1;, that istixed to the shift-rail ti, and at'the same time the ribbon-t arrier is elevated by means of an arm 42, formed upon sai'l brar het 113 and projez-ting forwardly therefrom beneath the foot oi the IilJlHm-t arrier.

Overt-brow of the ribbon-carrier when in up )er-ease position is prevented by the lower ent of one of the forks 2h, hit it is in the path 'of the projecting step 2-! and serves as a stop therefor. 'lbe overthrow of the ribbonearrier when the parts are in l()\\'('l' ase position is prevented by a stop 43 in the path of the projecting step 25, as at Fig. t'. This step 43 is pivoted at 44 upon the rear side of the segment or framework 5 and at its lowerend has a cam 45, with hi: it engages the side edge of bracket-arm 12, as seen at Figs. 2 and 6, so that when said brarlu-t-arm is being elevated it cams the stop 43 out of operative position, as at Fig. 2, so that it (annot interfere with the desired upward movements of the ribbon-carrier. A compressionspring 46 is provided to insure the proper vibration of the stop 43 when the parts are shifted back to lower-ease posit ion.

Variations may be resorted to'within (he 4 scopeof my invention, and portions of my im rovements may be used without others.
