Specification of Letters Patent. Application filed July 13, 1908. Serial No. 443,179.

To all whom it'may concern: p

Be it known that 1, CHARLES F. Morse, a citizen of the United States of America; and a resident of New York, county of New York, and State of New York, have invented a new and Improved Transfer-Ink and. Method of'Producing the Same, of which the following .is a specification. I I

My inventlon relates to that class of tra-nsfer inks which are employed in paper patterns, the design delineated by the ink being. adapted to be transferred from the pattern. to a 'fabric.- Two methods have been com-f monly employed in the past to bring about the desired transference from the attern to the fabric, the first being to app y heat. and pressure, and the second, moisture. The

would be the more desirable Which'it is desired to produce the designsdelicate nature that moisture is liable to seriously 1n ure them. It has been attempted .in the .past tomoisten the paper pattern'itself at the rear thereof so that the liquid-employedin thus moistening the transfer ink Wlll not be directly applied to the fabric, but so far fully accomplished.

It is the main object of my present inven tion to provide a transfer ink such as is ca able of being transferred by moisture apphed .to the back of the paper carrying 1t, thevto w being so small as to possibility of injury to the fabric. To this end amount of moisture necessary to be employed positively preclude the employ ingredients which, when mixed ether, produce a material, first, which 51 be readily soluble,'second, which will readily dry sufficiently upon the paper pattern so as to prevent the same from rubbingofi or sticking to other material super- Iposed thereon,

v and third, willhave suflicient ody to enable a number of impressions to be taken from it..

The further object of my invention is to provide such ingredients as will permit the use of mineral coloringmatter .therein, because later, when such material has been transferred to the fabric, the transferred design may be readily washed'out (wherethe abric is one capable of being thus washed) dificult, if not impossible to wash out the design onceit had can so transferred.

The ingredients that I. have so far em-.

erab

I am aware, this has never been success-v 5 loyed with very successful results are glu- I .cose, corn syrup, and glycerin, together with f the required mineral colors in quantity and shade to meet the proper'requirements. The

glucose and corn syrup act together as a .-vehicle for the colorin tute the main body 0 l'ycerin is used for the purpose of finally t inning the same down to the required consistency for use. condition is so thick and heavy that it would be practically impossible to properly combine it and the corn syrup together, and'it is, of course -highly undesirable to reduce the glucose y the employment of water, because this would dilute the material and render it Very much less eflicient for the work. For this reason I preferably reduce the lucose by the employment of heat, prefdy treating the same ina double boiler so as to apply the heat gently and in-not too great a quantity. After the glucose has been sufiiciently reduced in this manner I add the corn syrup in the desired proportion, such 'proport1on being, for instance, two parts of the syrup. to one part of glucose. The glucose is the element which gives the required tackiness to the rod-' not, such as is essential in an ink 0 this character particularly when employed in a printing press, but the glucose used alone would dry too quickly and too hard and would not be readily soluble enough when later it was required to make a transfer.

matter and constithe ink, while the The glucose in its ordinary Syrup when added has the efiect of keeplng the glucose in a readily soluble condition an prevents the cose are thoroughly mixed together the coloring-material may be added thereto; preferably this coloring material comprises the ordinary, mineral colors which may be ground in the aforementioned vehicle ust as such mineral colors are ordinarily ground in oil'and the like in the manufacture of paint. Thereafter glycerin may be added In glucose from drying too quickly or too hard.- After the corn syrup and glu 55- guantities sufiicient to bring the material own to the required consistency. This particular consistency varies in accordance with the method of emplo ment of the ink. If

the ink is to be emp oyed in ordinary flat bed printing presses a less ployed in the more rapidly moving rotary web quantity of glycerm isrequlred than if the ink is to be emresses. .,For flat press work I have foun that the addition of about %0f r 1 coming too brittle.

- ployed affectin intervals, if preferre proportions in The glucose and corn syrup I employ are such as are commonly sold on the market under those terms at the present day. The glucose contains'about 10% of free water, about 35% of dextrose, and about dextrin. The corn syrup, on the other hand, contains about 15% free water, and from 10 to 20% of molasses, the remainder being dextrose and dextrin in about the relative which they exist in the glucose. In other words, the corn syrup is a form of glucose, but it contains in addition thereto, from 10% to 20% molasses and a somewhat larger quantity of free water than that contained in'the material which I term herein the glucose element. In referring to glucose and corn syrup in the specification and claims herein, it will be understood that in the use of such terms, I intend to thereby define materials of the character above specified.

I have found that by employing the foregoing formula I produce a substance which may bereadily printed in substantially the ordinary manner upon a coarse open-grained paper, and that the ink thus printed upon the paper readily dries upon the surface sufliciently to enable the necessary handling of the paper patterns immediately they are printed, yet, I have found in practice that the ink remains very readily soluble for a long time thereafter and is so readily soluble that if a paper attern, prepared as above set forth, is laid face downward upon a piece of fabric upon which it is desired that the design shall be transferred, and the back of the paper pattern be but slightly damped, the design will be immediately transferred to the fabric without the moisture thus emthe fabric in any Way. have also foun that the same paper pattern may be used to give a comparatively lar e number of transfers, which transfers may fie made one after another or at considerable d. The paper pattern may be allowed to dry after one impression is taken and then later on another impression taken and so on,

I coloring or, with one damping a number of impressions mediately. If the pa er pattern is allowed to dry it may therea er be handled just as readily as before,that is to say, without there being any danger of the ink rubbing or otherwise coming off. I have also found that the ink prepared in this manner has no tendency to run, and that clean, sharp, and clear impressions are produced. I attribute this largely to the employment of the glucose, and the comparatively considerable uantity of glucose which I employ is renefed possible by the employment of the corn syrup.

It will, of course, be understood-that the proportions of the foregoing ingredients may be varied conditions.

What I claim is:

1. A transfer ink comprising a coloring material, a vehicle therefor comprising g1 cose and corn, syrup, and glycerin sufiicient to give the require consistency.

2. A transfer ink comprising a vehicle for coloring material, composed of glucose and corn syrup in the proportion of one part of the former to two parts of the latter, coloring material of the required quantity and shade and a sufiicient quantity of gl cerin to reduce the product to the require consistency.

3. A transfer ink comprisin a vehicle for coloring matter composed 0 glucose and commercial corn syrup in the proportion of one part of the former to two parts of the latter mineral coloring material of the required quantity and shade, and glycerin to an amount about equal to the glucose and the corn syrup.

4:. The process of producing a transfer ink which consists in first thinning glucose by the gentle application of heat, then mixing commercial corn syrup therewith in about the proportion of two parts of the syrup to one part of the lucose, and then adding a materia and sufficient gl cerin to reduce the product to the require consistency.
