1 Claim.' (Cl. 106- 271) 1 This invention relates to a composition of matter and method and process for reconditioning faded and worn typewriter and other duplicating ribbons.

It is an object of the present invention to provide a composition of matter or solution which can be applied to typewriter ribbons and to duplicating ribbons regardless of their color or combination of colors to revive and recondition the same and to extend their use whereby upon a simple application of the solution upon the ribbon, the ribbon can be prepared for further use on allowing the solution a little time to soak in and dissolve the dried out ink in the ribbon.

It is another object of the present invention to provide a solution for reviving faded type- Writer ribbons and the like that can be compounded from readily available substances and which can be applied every few days upon the ribbon so that the ribbon will not be allowed to dry out and wherein the life of the same will be greatly extended and wherein this can be effected upon the ribbon without the removal of the ribbon from the typewriter or other machine.

Other objects of the present invention are to provide a solution for reconditioning typewriter ribbons which is inexpensive to compound, quick acting, may be applied with a brush or with a medicine dropper, will not affect other parts of the machine and efficient in operation.

For other objects and for a better understanding of the invention, reference may be had to the following detailed description taken in connection with the accompanying drawing, in which Fig. 1 is a perspective view of the top of a typewriter and of the solution being applied to the open ribbon cage.

Fig. 2 is a perspective view of the top of a typewriter where the cage is not of the open type and illustrating the application of the solution to the tape or ribbon near the cross-bar.

Fig. 3 is a perspective View illustrating the manner of applying the solution upon a horizontally extending tape by the use of a brush.

Referring now particularly to Fig. 1, l represents a typewriter having the usual typing roll I I, a ribbon l2 and an open top ribbon reel l3. This ribbon extends through the crossbar l4. According to the present invention, the solution, which will be hereinafter described, is applied to this ribbon by simply dropping with a medicine dropper l 5 the solution on the edge of the ribbon and through the openings, as indicated at H), in the top of the reel l3. This operation can be efiected the evening before and by morning or twelve hours thereafter, the solution will have been soaked in and will have dissolved the dried out ink in the ribbon. Fifteen to twenty-five drops of the solution, depending upon the condition of the ribbon, can be used. The ribbon is kept tight while the solution is being added. The dropper is moved back and forth across the top of the ribbon. After applying the solution, the ribbon should be tightly rewound on the other spool. 1

If the typewriter has a spool or reel I! which is of the closed type, as shown in Fig. 2, the solution can be applied with the dropper by placing drops directly in the center of the ribbon, near the cross-bar l4, so that the ribbon will have a firm backing for the dropper and also in order that the solution will not stain the roller 1 l. The ribbon is wound while the solution is being applied with the dropper every few inches. After applying this solution to the ribbon, the ribbon is Wound up tightly upon the other reel. If the typing becomes smudged or blurred, less solution is used. If the typing is too light, more solution is used.

If the solution is to be applied to a wide ribbon of a duplicating machine, the same medicine dropper is used in the manner as shown in Fig. 3 or a paint brush I9 is drawn over the ribbon 2! to distribute the solution thereover.

The solution is formed of three parts, part I, part II and part III. Part I comprises per cent by volume:

Pe cent Butyl acetate 25 Butyl alcohol 10 Ethyl alcohol 10 Toluol 55 Part II comprises by volume: three parts sperm oil and one part kerosene.

Part III comprises by volume: eight parts citronella terpenes; two parts cinnamon leaf terpenes; one part dipentene; one and one-half parts oil citronella; and five parts oil lemongrass.

Once the parts have been formed, they are then mixed together in the following manner: three gallons of part I; one gallon of part II; and sixteen ounces of part III. This mixture forms the complete composition. The parts can be mixed together with any volumetric measure, such as fluid ounces, pints, gallons, or any other convenient unit according to the quantity of the product to be made up and thereby keeping the same parts throughout.

This final solution is used with the medicine be understood that such variations in these meas ures and in the method of application shall beg within the spirit and scope of'the present inven-- tion as defined by the appended claim.

Having thus set forth and dis'closedithe nature:

of my invention, what is claimed is:.

A solution for reviving and. reconditioning V faded and worn typewriter or duplicating'ribbons, regardless of color or combination of colorslcomprising three parts, one of said parts having twenty-five per cent butyl acetate tenlper cent butyl. alcohol, ten per cent ethyl alcohol and. fifty-five per cent toluoll; another part having three portions. sperm oil and one portion kerosene; the. third .part having. eight parts citronellaterpenes, two parts cinnamon leaf terpeneaone part dipentene, six and one-half parts oil citronella; said three parts being combined in the following proportions: three gallons of part I, one gallon of part II and sixteen ounces of part III.
