Oct. 29, 1963 W. J. ROONEY INKED TYPING RIBBON WITH CLEAN REPLACEMENT MEANS Filed Jan. 2, 1962 FIG. 4

United States Patent 3,108,675 INKED TYPING REEBGN WITH QLEAN REPLACEMENT MEANS Wiiiiarn J. Rooney, 670 Corliss Ave., Philiipshurg, NJ. Filed Jan. 2, 1962, Ser. No. 163,474 Claims. (Cl. 197-172) This invention relates to an improved ribbon for use in typewriters, and all other ofiice and similar machines whim employ inked ribbons for printing typed matter, and one of its objects is to provide an inked ribbon system which eliminates the manual feeding of ribbons through the typewriter guides, after an initial ribbon has been properly threaded in service position in a typewriter or other machine which uses an inked ribbon for printing, so that a typist or other machine operator will not soil her fingers in placing a new inked ribbon in service position.

Another object of the invention is to provide an inked ribbon with a self adhesive paper or thin material coupling on its leading end and a coupling strip which is wound on the companion ribbon spool and which remains in feeding relation to the ribbon guides at all times, and is made up of sections of relatively short lengths, which are easily detached from one another, so that an exhausted inked ribbon can be withdrawn from service, after this coupling strip has been severed from the self adhesive paper or other tab carried by the used ribbon.

A still further object of the invention is the provision of a coupling strip for inked ribbons, which is formed with a plurality of longitudinal slots, spaced apart lon tudinally from each other, to permit the pivoting of release or reverse mechanism operating levers carried by spools of certain construction, which automatically release and reverse the ribbon feeding mechanism when the spool has discharged its length of inked ribbon.

A further object of the invention is to provide a special stop clip and a terminal adhesive tab, which adapts my invention to typewriters having ribbons provided with stop eyelets. I

With the above and other objects in View, the invention comprises wrtain new and useful constructions, combinations and arrangements of parts, clearly described in the following specification of the accompanying drawings, showing my invention, and in which:

FIG. 1 is a plan view of a pair of ribbon spools showing the inked ribbon of one spool connected to the coupling strip of the other spool.

FIG. 2 is a side elevation of the adhesive tab and a connected portion of the inked ribbon and a considerable length of the coupling strip, showing the transverse weakening lines of the latter, which provide detachable sections thereof for successive coupling to the adhesive terminal starting tabs of inked ribbons.

FIG. 3 is an edge view thereof.

FIG. 4 is a side elevation of a portion of a coupling strip having spaced apart longitudinal reverse :lever releasing slots and transverse weakening lines.

FIG. 5 is a similar view of another portion of this coupling strip, showing an adhesive tab for securing the coupling strip to a ribbon spool.

FIG. 6 is an edge view of the adhesive terminal tab and the engaged coupling strip showing a slip-on stop clip.

FIG. 7 is a similar view, showing the coupling strip positioned to engage the adhesive terminal tab.

FIG. 8 is a detail edge view of the adhesive terminal tab for the coupling strip.

FIG. 9 is a detail side view of a self reversing ribbon spool, of well known construction, showing the release slot of the coupling strip aligned with the release lever.

FIG. 10 is a detail side view of a spring stop clip.

3,1b8fi75 Patented 0st. 29., 1963 FIG. 11 is a detail cross sectional view of the terminal tab of the inked ribbon, showing the stop clip in place thereon.

FIG. 12 is a detail sectional view of another form of a stop clip, which is interlocked with the inked ribbon.

FIG. 13 is a side elevation of another form of a slip-on clip to reverse the ribbon feed.

FIG. 14 is an edge view thereof.

Referring to the accompanying drawings, which ill-ustrate the practical embodiment of my invention, 10 designates a ribbon spool having a fresh inked ribbon 11 wound thereon. The outer end of this ribbon 11 is provided with a self adhesive paper tab 12, which engages both faces of the ribbon by its flat sections 12a and 12b, and the section 12a is extended beyond the section 1217 to provide a self adhesive coupling tab portion 13, which extends outwardly or endwise of the end edge of the inked ribbon 11.

The inked ribbon 11 is wound on the companion spool 14, and on the tubular hub 14a of this spool the inner end of the coupling strip 15 is wound, and this inner end may be provided with a self adhesive tab 16, which initially may be folded and thus secured to both side faces of the coupling strip. When it is desired to connect this coupling strip to the spool hub one wing of the self adhesive tab is separated from the strip '15 and then attached to the spool hub, as shown in FIG. 6.

The coupling strip 15 is constructed of flexible ribbon or material which will not stretch, and is formed with a series of transverse weakening lines 17, which are dis posed at right angles to the length of the coupling strip and which are spaced apart equal distances from each other. These weakening lines are shown to be formed by small perforations, but any other form of weakening may be employed.

The self adhesive tab 12 is formed with a notch 12c on its upper edge which is engaged by the U-shaped spring clip 18, which has a slip-on fit on this tab, and is held from longitudinal shifting by engagement of the notch 120. This spring clip serves to do the work performed by eyelets, in reversing the ribbon feeding mechanism.

When the inked ribbon is exhausted and is no longer of service value, it is disconnected with the coupling strip, by severing the end section 17a of this coupling strip. When a fresh inked ribbon is placed in service position, the endrnost section of the coupling strip is again engaged with the self adhesive tab of the inked ribbon, using a ribbon so provided or equipped.

As the self adhesive tab '12 is free of ink and clean, the typist or other machine operator can freely handle the inked ribbon, thus protected. The connecting of the outer end of the coupling strip with the replacement inked ribbon takes place, while the coupling strip is properly threaded through the ribbon guides of the machine. When the receiving ribbon spools starts to wind up the inked ribbon, the coupling strip is first wound on the spool, and as this takes place the inked ribbon is moved step-by-step through the ribbon guides, and automatic winding and reverse winding of the ribbon then continues until the inked ribbon again requires replacement.

The inked ribbon may be initially provided with the coupling strip, which being completely free of ink, can be threaded through the ribbon guides Without the operator or user soiling his or her hands.

When inked ribbons are used on spools which are provided with built-in reverse operating levers, such as 25, in FIG. 9, the coupling strip 26 is formed with longitudinal slots 26a, spaced apart longitudinally from each other, and of sufiicient number to permit the outer end of the release and reversing lever 25' to freely pass through the successive turns of the coupling strip on the ribbon spool, so that automatic reverse of the ribbon feed takes place.

The coupling strip should have a total length suflicient to make several turns on a ribbon spool, and when initiaily or factory connected with the inked ribbon, provides a protective covering for the inked ribbon on the spool.

The spring clip 18 is of U-shaped and has a spring bend 18a on its upper end, which provides a finger grip for placing the clip on the ribbon terminal tab, and for removing it.

The notch 120 formed in the replacement strip 12, permits the U-shaped spring clip 18 to be mounted astride the ribbon, so that the connecting bend of this clip can be disposed below the upper edge of the ribbon, and the upper end of the clip will not get caught in the reversing lever of the ribbon mechanism, and obstruction of the ribbon feed will be avoided. The clip is constructed so that its lower end will not project below the lower edge of the ribbon. This construction prevents the clip from binding in either of the feed spools, as the ribbon is wound and unwound. This spring clip does not pierce the ribbon fabric, and is held in place by the initial tension of he clip, the l gs of which are in contact with each other before the clip is mounted on the ribbon.

The lower ends of the spring clip are divergent from each other, so the clip may be readily forced on the ribbon, and this construction permits of the removing of the clip from the ribbon.

In FIG. 12 I show another form of the spring clip, which comprises a member having an inner leg 27 connected by the U-bend 27a to the intermediate leg 27b, and a third or outer leg 27c, which is formed with a piercing prong 27d, adapted to be forced through the hole 27c formed in the inner leg 27. This clip is placed astride the ribbon tab and the bendable outer leg 27c is forced toward the inner leg and the prong 27d is forced through the leg 27 and through the terminal tab of the inked ribbon and clinched against the inner side of the intermediate leg 2%, thus securing the stop clip in service position, against displacement in all directions.

In FIGS. 13 and 14 I show a modified form of the stop clip; which consists of a wire form having a U-shaped outer form or part 30, providing parallel bars 39a and 36b and a connecting bar 3%. To the upper end of the leg or bar 30a a cross bar 3th! is connected, and an inner U- shaped form or part 300 is formed on this cross bar 33d. The upper cross bar 30d is offset, as shown in FIG. 14, to provide a finger hold, and the cross bar 30 of the inner U-shaped part 313e, is also offset at 30g, so that the user can more easily slip the clip on the ribbon tab.
