L. ALLEN ETAL ,888,154 MANUFACTURE AND PRODUCTION OF TRANSFERS Fil ed Oct. 19, 1928 v INVENTORS LEONARD ALLEN 1 I ERNEST CHARLES sesame Patented Nov. 15, 1932 UNITED. STATES PATENT OFFICE MANUFACTURE AND PRODUCTION OF Appllcation filed October 19, 1928, Serial No. 318,641, and in Great Britain March 16, 1928.

This invention relates to printing lustre or liquid metal transfers, which may or maynotbe combined with colors, on paper by means of letter press, copper plate, or other printing processes, and subsequently applying the transfers to pottery, glass, enamelled iron, jewellery or the like.

In the drawing Fig. 1 is a broken perspective view of a simplex paper with a transfer impressed thereon according to our invention.

Fig. 2 is a longitudinal cross section view of the combination shown in Figure *1.

Fig. 3 isa broken perspective view of a duplex paper with a transfer impressed thereon.

Fig. 4 is a longitudinal cross section view of the combination shown in Fig. 3.

carrying out our invention the transfers 3, which may be of liquid metal or lustre, are printed upon either simplex or duplex paper, as shown in the drawing.-

These papers are well known in the art. In the case of the simplex paper shown in Figs. 1 and 2, the paper consists of ordinary paper 1, having a glazed surface 2, upon which the transfers. may be impressed by known printing rocesses such as letter copper p ate, or the like. In plex paper, shown in Figures 3 and 4, the

paper consists of ordinary paper 1 up0n Y which is superimposed tissue paper4 coated the transfers may be so as to have a glazed surface 5 upon which impressed in the same paper. The glazes 2 of vegetable or any other size that is usually found on commercial transfer papers. The composition of these glazes is optional and forms no part of the present invention.

If desired, colors 6 may be combined with the liquid metal or lustre transfers. If colors are to be used two or more superimposed registering impressions may be made so as to produce the sufficient body in the print.

The H uid metal hereinbefore referred to is well own in the art and consists-of metals such as silver, gold or the like which after having been finely divided are disway as with simplex and 5 may be contains a high percentage terial, which will press, offset, the case of dusolved or suspended 'is essential oils. If dename, or mew BARNET.

sired these solutions may contain two or more of these metals.

We have found that a single impression is suflicient to yield highly satisfactory trans fers if the liquid metal or lustre, which terial is heated to the state where a certain proportion of the volatile oils are driven off and the liquid metal or lustre becomes of resinous mamore or less permanently tacky and approaches the point of decomposition, the resultant product of being thus more easily and economically worked both for printing transfers generally by any printing process and in particular for printing in letter press or offset printing and also in copper plate methods. After printing on the paper the film shortly becomes dry and hard.

In order that these transfers may be transferred to pottery, ellery or the like used is made of the fact, above stated, that the liquid metal or lustre contains a high percentage of resinous mabecome tacky at elevated temperatures. To eflect transference, the

article, or object to be decorated is first slightly moistened and the said transfers are then applied face downwards in the usual manner, when the article or object is suitably heated. The paper with its adhesivecoating is subsequently removed by washing or by any convenient method with or without cool- The following examples further serve to illustrate how the transference may be effecteid onto the articles or bodies to be decorate Example 1 The article to be decorated is slightly moistened and the transfer is applied, when the article is heated to about 50 to Centi rade. After cooling, the paper with its a esive coating, is removed by washing with water.

- Example 2 The article to be decorated is heated to about 50 to 70 (man-n.1,. I... l-

liquid metal or lustre glass, enamelled iron, jewthus be obtained pertheiiii transfer paper,

are then applied and after cooling, the paper is removed followed by washing in the usual way as described in Example 1.

Ewample 3 The article is moistened .with warm water, the transfer applied and the paper removed, followed by washing as already described.

Ewample 4 The article is moistened and the transfer applied and pressed down by rubbing with a hot dry cloth; the paper is then removed followed by washing as already described.

Ordinary ceramic colour transfers, as now made may have additional details in liquid metals or lustres added, and the transfers so treated are transferred by the methods we have described. As however these methods of transference are not entirely satisfactory as regards the colour portions 6, one of the following alternative methods may be adopted according to this invention which yield very satisfactory results.

The colour portion only on the transfer is printed or painted over with a thin film 7 of resinous material for example a solution of resin in a volatile oil and the transference is then carried out according to one of the methods already described.

Alternatively instead of printing the colour transfer by employing an oil or fatty medium with the colour, the medium used is a solution of a resinous material which introduces the required resin for the transference an the transfers can then be printed for example in a letter press a copper plate and perfect transference can with mixed metal, lustre and colour transfers.

Whentransfers are printed on duplex par and thinner surface ortion of the pape with; the transfer t ereon .is stripped from the under or heavier portion of the paper the body to be decorated.

It will be understood that the adhesive coating to be removed from the article after the application of the transfer is that contained on the ordinary duplex or simplex but in order to obtain th most satisfactory results from the point of view of brilliancy with liquid metal or lustre transfers we preferablyfiuse a specially prepared transfer paper in w ch the amount of adhesive coatin used is reduced to a minimum. This is 0 surfaces, while on practically flat surfaces the adhesive coating may 'be entirely dispensed with, a surface hardened paper being used in order to obtain a good print for transference. After transference the article may be fired, as is customary in transfers, but this step forms no part of the ration of articles having a smooth or offset machine or from A before applying the transfer to present claim it.

What we claim is 1. The manufacture of transfers for decorl on of articles having a smooth, glass-like surface, comprising printing transfers of finely divided metals in essential oils, upon transfer paper.

2. The manufacture of transfers for decoglass-like surface, comprising printing trans ers of fine- 1 divided metals in essential oils, upon transer paper havin a minimum amount of adhesive coating t ereon.

3. The manufacture of transfersfor decoration of articles having a smooth, glass-like surface, comprising heating a quantity of finely divided metal which has been mixed with essential oils, "to a point whereat the substance becomes tacky and readily usable in a printing press and after printing will adhere to articles merely upon the application of a low degree of heat, and printing with said heated mixture upon a transfer subsequentl printing with such mixture invention and therefore we do not.

upon trans er paper, printing color transfers aper, and painting over said colors m of resinous material prior to efon said with a d fecting transfers from the paper to the article to be decorated.

In testimony whereof we names to this specification. LEONARD ALLEN.
