15. it known that I, GEORGE \V. RAMSEY, residing at Peoria, in the county of Peoria, P late ol' lliinois, (whose post-office address 9072 \Vestory Building, Washington. District of Columbia), have invented certain new and useful Improvements in Type- Writer Ribbons, of which the following is a specification.

This invention relates broadly to the art of printing and specifically to the type writer, and kindred. arts.

The object of the invention is to provide a means for forming a distinctive imprint, which distinction is not dependent on the type "face or upon the color of the transferred pigment.

A further object is to provide a means for causing: the carbon, or duplicate copy, to be an ihdicutirely true mpy of the original sheet.

This inrcnt broadly new. i strut-t i a r 5! l chun is believed to he a. Without departing born the scope tlurreoi', but :1 preferred form will be ln-reinot'ter sperifi llydescribed by refer-- euro to the drawings which form a port of this s iecitiration. mid the scope of the hirer]- i-ion will be indicated by the claims.

intervals betoeen the warp threads of the ribbon, a. ribbon is formed that will produce it distinguishing imprint, and will cause the distinguishing characteristic to be also imprinted through on a carbon orwluplicate sheet. And by varying the directions of the piano wires with relation to the ribbon, in each difl'erent field of color of the ribbon, the carbon becomes an indicatively true copy of the original sheet.

Fig. l. is a diagrammatic representation of the printing elements ofv a typewriti'ng machine, in which the key lever l, is fulcrumed on a key lever rod 2, and is adapted to operate the sub-lever 3, which in turn operates the type bar 5, through the links 4. As the actuation of these parts are so Well known to those skilled in the art, a further description thought to be unnecessary. T he platen (i, is showniis carrying thereon an original sheet 9, a carbon sheet 8, and a diu'iliiiiate sheet 7'.

Beneath the key lever 1, is a universal bar 10, which connected by links 11, with the rot :er lever 12, vibrates the ribbon carrier, or v brator 13. Thus at each. stroke of the key the ribbon is carried tothe printing point. .Theribbon change device 14. I have indiciiteiil as being carried by the ribbon vibrator itself in such manner that the ribbon .A may be shifted to any desired printing field after the manner well known in the typewriting art. As this mechanism forms no part of my invention I have illustrated the above parts in a diagremmatical manner. The ribbon Which is shown in cross section in the vibrator, is disclosed as having two printing fields of different structurev The upper field A. representing the ordinary plain or black field of the printing ribbon. The lower portion B is of it differently colored field and shmvn as containing piano wires in :1 manner, and for a. purpose, as will be more fully explained later in this spec-i 'llCftilOH.

lr. l ir; i. in which arch ifliii ereut printing: tiel-sls are diagrammntierdly re iiresented. In this fig ure :1 miter: of the Weave which will be iml'liitli the import or imprint of the type r. is a design oi longitudinal uniii. is. the entie longitudinal al the particular printing field is of "120 rdll'l design. This invention however, so contemplates a. design that may very in printing ribbon is illustrated print will be changed automatically as the ribbon is being fed through the ribbon guide, as it is being wound on the ribbon spools, in the usual manner.

Referring more particularly to Fig. 3, field A. represents the black portion of the ribbon; field B indicates the red portion of the same ribbon; C indicates the purple or other colored field of the ribbon. The black portion A of the ribbon is woven in the usual manner. In the red portion B of the ribbon, piano wires ((1) of small cross section are introduced among the warp threads at determinate intervals, for example at every third thread. In the purple field C, of the ribbon the piano wires (a) have a direction different from that in the red printing field. It is also obvious that the printing ribbon formed to determine the character imprint by the structure of the ribbon, may be made in a single color and yet obtain all of the advantages of amulticolor ribbon, without any of the disadvan- "tages of the same. But again referring to the combination of the multi-color with the structural distinction, each multi-color field may be formed of a different structure.

-Referring to Fig. 4, the warp threads (a) indicate piano wires; the threads (7)) are formed of cotton, silk or other fibrous threads. The filler thread (0) is bound beltween the warp threads (a) and (t) by means of the woof threads (d) and (e). The face of the ribbon beneath which immediately lies the piano wires (a), is adapted to be used as the printing face. lhe face of the ribbon opposite thereto becomes, because of the filler threads 0 and the warp threads I), a pad adapted to hbld ink and a. cushion against which the type strikes, thereby preventing said type face from being destroyed by direct contact with the piano wires. It will be seen that I may .vary the direction of the wires in the ribbon, and thereby form a distinctive variation in the character of imprint for each color of the printing ribbon.

Fig. 2, indicates a modification of the method of varying the character of imprint from the printing ribbon. In this modification one field of the ribbon ((1), corresponding to the field b in Fig. 3, is woven in such manner that the threads are more or less separated from each other. and are adapted thereby to produce a varied or uneven imprint. The other field, correspending to a. Fig. 3, is woven in the usual manner as is wellknown in the art of typewriting ribbons.

I have found that it is not necessary to form the character distingui hing threads or wires (a) of piano wires, since tightly twisted threads of any fibrous substance, being sufficiently solid to transfer its character of imprint on the paper and through to the duplicate sheet, will accomplish the desired result.

In Fig. 5, (7) indicates the usual character of imprint from the black field of the ribbon. (g) indicates the character of imprint from the red field of the ribbon, the said imprint from this field showing an uneven appearance because of the longitudinal wires in the red field of the ribbon. (It) indicates the character of imprint from the purple field of the printing ribbon, which shows a different appearance from that shown in the other fields.

A printing ribbon constructed in the manner as above set forth will cause a carbon or duplicate sheet to indicate which field of the ribbon was struck by the type at the printing point, and thus the carbon sheet becomes an indicatively true copy of the original sheet. This invention also contemplates the use of a single colored ribbon having various printing fields therein woven in such manner as to cause each field to make a different imprint. In this manner the full advantage of multi-color work could be attained and yet have the work in a single color. This is of advantage and use in certain ofiicial papers where multicolored inks are not allowed.

As many changes could be made in the above structure and many apparently widely different embodiments of this invention could be made without departing from the scope thereof, the definite matter contained in the above description and shown in the accompanying drawings is to be taken as illustrative and not in a limiting sense.
