TYPE-WRITING MACE-NE.

Specification of Letters Patent.

Patented June 25, 1907.

Application filed September 7, 1906 Serial No. 277.429-

To all whom it may concern:

Be it known that I, EDWARD F. KUNATH, a citizen of the United States, residing in Jersey Cit State of ew Jersey, have invented certain new and useful Improvements in Type-Writfollowing is a specification.

This invention relates to the ribbon mechanisms-of typewriting machines, and particularly to means for bringing into use differ- .stretch a ribbon of red ent colors of ribbon at will.

I provide two or more separate ribbons of different colors and movable independently of one another to cover the These "ribbons are Wound simultaneously upon the usual ribbon spools; and means are provided for causing either ribbon to cover and uncover the printing point during the tglpe strokes While the other ribbon remains 1 e.

I illustrate my Well known ing machine, in which the usual spools for the usual ribbon are mounted upon vertical axes one at each side of the printing point in fronit of the platen. Behind said ribbon, I or other special color, which is wound up simultaneously upon the spools with the usual ribbon. I provide an individual carrier or vibrator for eachof the ribbons, one carrier in'front of the other. Said carriers are shown movable up and down by means of levers. The latter may be substantially like those commonly used in the Underwood machine, and may be mounted side by side, either lever being called into operation at the type strokes. The lever-operating mechanism includes the usual universal-bar frame, which reciprocates at each type stroke. Upon said recip rocating member I mount actuators, one for each of said. ribbon-vibrating levers," said actuators being shiftable to engage either one or the other lever. Means are. provided for detaining the actuators in either shift position. Means are also provided whereby the actuators may be held in such aposition that neither lever will be operated, so that neither ribbon is caused to cover the printing point at the type strokes, this being a convenience when making stencils.

In order to prevent ink offsetting from one ribbon to the other, the ribbonnearest the invention asapplied to the in the county of'Hudson and" printing point.

Underwood front strike W1it-' the platen, so that ink may not transfer from the other side thereof to the other ribbon. Each ribbon may be inked only on the-side facing the platen' There may also be inserted between the ribbons a flexibleinkproof separate protective strip.

As so far described the partsare'in common use upon said Underwood machine. Said ribbon 6 is threaded through an upstanding carrier 23 loosely pivoted at 24 to "the front end of a n front of the lever 25, which is pivoted upon a shoulder screw 26, the latter threaded into a bracket 27 fixed upon the rear side of a horizontal shift rail 28. Said lever 25' has'an' arm 29 extending up from said pivot 26 and pro vided whereby the lever is operated during the backward and forward movement of said universal bar frame or table 21, in a manner presently to be explained.

In rear of the main ribbon 6, I stretch a supplemental ribbon 31 of red or other speclal color, which extends between said spools, and is wound thereon simultaneously with said ribbon 6. The ribbon 31 is threaded through a ribbon carrier 40 mounted directly behind thecarrier 23, and having ears 4L1 to embrace a which in said machine is the type-gm fixed. vertical "post. Said-ears 41 it will be understood-also confine the carrier 23 against lateral* dislacement.
