' COMPOSITION OF MATTER FOR TRANSFER DESIGNS.

I 6 has marked advantages over the former compositions used in this line of manufacture;

In making designs for embroidering, a material which is normally solid is heated until it becomes fluid and forms an ink which is 10 picked up by a recessed roll which is wiped clean except for the recesses and then paper which is passed over the roll receives this ink which is in the recesses of the roll and after the ink has hardened on the paper it can be transferred to cloth by laying the paper,

usually tissue paper, on the cloth and passing a hot iron over it. These designs are usually a series of dots, and ink heretofore employed has some defects such as causing the sheets of tissue paper to bestuck together when it is hot weather or if made harder is apt to chip off of the paper and particularly if the paper is rumpled.

The paper design sheets are kept in stock in piles until wanted so that it is desirable to have an ink that will not stick in high temperature and, furthermore, since these sheets of paper are folded, very often, and distributed in envelopes it is necessary that the ink adherents the paper until it is wanted for. transfer to' a piece of fabric which is to be. embroidered or provided with other forms of needlework according to the design.

' An advantage of my improved composition of matter is that it can be used in marking both black and dark material and also for marking white or light materials, thus avoiding the necessity of cleaning out the ink troughs and other parts of the machines which do the printing thus, not only causing economy in the manufacturebut making the pattern sheets of universal use inthe one color whereas the old practice has been to make a separate printing in a very light color for dark material and to provide pattern sheets with dark ink for use on light material. This is now done away with as my new composition provides for a single line of patterns for use on material of any color. The material is normally in solid form and is heated to a liquid form in the machine and I use a composition consisting of a resin having a highacid number, rosin, a wax, stearic acid and a suitable coloring. I have provided as a resm such as material as Cumar gum, a neutral gum which 1927, Serial No. 181,893.

when combined with the resin having a high acid number gives to theipatterna positive thickness making it appear more embossed, that is, the design is raised higher from the paper and thus gives it the necessary body. It does not chip, however, because rosin or a resin having a high acid number when combined with the stearic acid which I employ in suitable proportions together form a mixture which becomes adhesive and it penetrates into the paper and prevents what was a defect in the old compositions.

The wax which must be of high melting point, such as carnauba wax, also is of advantage because it hardens quickly and by the time the paper passes from the printing roll, sixor eight feet from the winding roll, the

ink or the paste is set and hard enough for rolling the paper'up on a spindle.

In the matter of coloring I can use any dye soluble in oil and which will withstand the heat necessary in melting the compound, likewise any soluble pigment or earth color of suitable characteristics. I use ultramarine blue ink and a special white ink which white ink consists of 78 percent of Titanox and 22 percent litho varnish ground to a thick paste. The above mentioned Titanox' consists of 25 percent titanium oxide and 75 percent precipitated barium sulphate. The above mentioned earth color may be used in a dry state but is more difficult to mix in the compound. The proportion of the various ingredients in the preferred form of solution is as follows: the

parts being by weight; 16 parts Cumar gum a synthetic gum) 4: parts rosin (colophony) 4 parts carnauba wax, 2 parts stearic acid (double pressed), 8 parts ultramarine blue ink. and 40 parts of special white ink.

This material is mixed together and'when cold forms a solid which is heated to the proper consistency when it is to housed in the printing machine- I claim:

-' A composition of matter for making transfer designs comprising Cumar gum, rosin,

carnauba wax, stearic acid and a coloring matter consisting of ultramarine blueink and a special white ink containing Titanox and litho varnish, the Titanox containing, in turn,

tiltlanium oxide and precipitated barium sulate.
