TYPE-WRITING MACHIN E.

SPECIFICATION forming part of Letters Patent No. 472,612, dated April 12, 1892.

Application filed October 9, 1891. Serial No. 408,243. (No model.)

this specification, and to the letters of refer ence marked thereon.

With the ordinary type-writer, in which the characters are impressed on the printing-surface through an interposed inked ribbon, the words or characters to which particular attention is desired to be directed are usually underscored or capitalized.

It is the object of my invention to provide means wherebysuch words or characters may be brought to the attention more prominently and be more quickly and easily distinguishable from the body of the work, and this, too, without in any way interfering with the ordinary running of the machine and without entailing any extra labor or trouble on the operator. These results-I accomplish by interposing between the usual ribbon on the machine and the printing-surface an auxiliary ribbon of different color, so that the desired words and characters will be printed in a color different from those in the body of the work, all of which I will now proceed to describe.

In carrying my invention into effect I provide a piece of type-writerribbon of the desired length and color, preferably red, and locate on one side thereof a strip of paper or other suitable protecting material. To the ends of the auxiliary ribbon I secure clips or end pieces of any suitable material-such as tin, celluloid, or leather-by suitable fastening devices or otherwise. In the example shown the end pieces are made of leather and are secured by means of fasteners passing way through the leather end pieces, ribbon, and paper strip. These clips or end pieces serve to hold the protecting-strip and ribbon together and prevent the fingers of the operator from becoming soiled in handling the ribbon and also by their weight assist in keeping the auxiliary ribbon in place when in use.

In the accompanying drawings, Figure 1 is a perspective view of a type-writer, showing the auxiliary ribbon in operative position. Fig. 2 is an enlarged perspective view of the auxiliary ribbon, the ribbon being broken away to show the underlying protecting-strip. Similar letters of reference in the several figures indicate the same parts.

The letter A indicates the ribbon, broken away to show clearly the strip of paper or other suitable material B underlying the same.

0 indicates the end pieces or clips, and D the fastening devices for holding the ribbon and paper strip together.

In usfiwh'en the operator desires to print certain words or characters in a different color from the body of the work being done to emphasize the same or for other reasons he simply places the auxiliary ribbon across the type-basket over the ribbon on the machine, so that the protecting-strip will lie between the two ribbons, the ends of the auxiliary ribbon resting on opposite sides of the machine, and then proceeds to use the machine as ordinarily.

For all ordinary purposes the Weight of the auxiliary ribbon and end pieces will be sufficient to hold the same in place as long as necessary, at the same time allowing it a slight movement to present new surfaces at the printing-point, and as the protecting-strip is interposed between the two ribbons there will be no blending of the two colors, and thus the different-colored writing is brought out clearly and distinctly.

It will be seen that the means employed are I very simple, can be easily and quickly putin place and removed with practically no trouble, and the running of the machine for ordinary purposes is in no way interfered with.

Having thus described my invention, what I claim as new is- 1. In a type-writer, the combination, with the ribbon, platen, and printing mechanism, of a relatively short auxiliary ribbon of different color interposed between the ribbon on the machine and the platen, as and for the purpose described.

[0 piece of inked ribbon having a protectingstrip of paper or other suitable material on one side thereof and end pieces or clips,substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing wit- I5 HBSSGS.
