MOUNTI NG FOR LEAF Original Filed Dec. 2, 1931 INVENTOR WILL/AM 5. JONES BY 4%3 4 M? .4 I A OR EYS Patented Nov. 24, 1936 UNI-TED STATES PATENT OFFICE Divided and this application November 23, 1934, Serial No.'754,396

2 Claims.

My invention relates to a new and novel mounting for gold or other precious metals in leaf form, the present application, which is a division of my Patent No. 1,998,506, issued April 23, 1935, being directed to securing metal leaf to the surface of aluminum foil, adapting the material for use in heat embossing for the ornamentation of leather, cloth and other materials.

It has been cutomary heretofore to mount gold or other precious metals in leaf form upon a sheet or ribbon or tape of paper, the metal leaf being attached to the paper by a suitable adhesive such as wax.

After the metal leaf has been mounted on the paper a suitable size, such as French varnish, is applied to the surface of the precious metal.

Upon the application of heat and pressure by a die to the material so prepared, the adhesive will be melted, permitting the paper to be separated from the metal leaf, the size causing the metal leaf to adhere to. the surface being ornamented. If desired, of course, the size may be applied directly to the surface of the material tobe ornamented instead of to the surface of the metal leaf. One of the objects of the present invention is to mount metal leaf upon metal foil, such as aluminum, tin, lead, etc., as I have found that the use of a metal foil, by reason of its heat conducting and non-absorbent characteristics will greatly enhance the burnishing effect of the metal leaf to be applied to an embossed surface.

A further object of my invention is to provide a suitable supporting medium for the metal leaf that is not destroyed during the burnishing operation, but can be reclaimed and used again.

In the drawing: Fig. 1 illustrates one embodiment of my invention in which the metal leaf is applied directly to a sheet of metal foil; Fig. 2 illustrates an embodiment of my invention in which a sheet of metal leaf is attached to a sheet of metal foil by an adhesive;

Fig. 3 illustrates a roll of metal foil in ribbon form with metal leaf secured directly thereto; and Fig. 4 illustrates a roll of metal foil in which metal leaf is secured thereto by an adhesive.

Referring to the drawing in detail and first of all to Fig. 1, A represents a thin sheet of aluminum foil, about the same thickness as the paper upon which gold leaf is usually mounted. To

one surface of this sheet of metal foil is directly applied a sheet of gold leaf or other precious metal designated B.

To the surface of this gold leaf is applied a suitable size such as French varnish and desig- 5 nated C.

In use, as will be appreciated, the sized surface of the leaf is applied directly to the leather, cloth or other surface to be ornamented and a heated die applied to the back of the foil A. The heat 10 of the die will cause the size to attach the leaf to the surface being ornamented, whereupon the foil can be stripped or separated from the leaf and reclaimed.

I have found that the metal foil is very ad- 15 vantageous in this class of work in that it Will not curl under heat and by reason of its heat conducting characteristics, being an excellent conductor of heat, will greatly enhance the burnishing effect on the metal leaf. 20

The use of the metal foil is of further advantage in that the step of applying adhesive to the foil is eliminated, the leaf in this embodiment of my invention being mounted directly on the foil.

In Fig. 2, I have shown an embodiment of my 25 invention similar to that illustrated in Fig. 1.

A designating the aluminum foil, B the gold leaf or other precious metal, and C a size. In this embodiment of my invention, however, I employ adhesive D for attaching the leaf to the foil. I 30 have obtained good results employing sour milk as the adhesive D, although a material like paraffin gives fairly good results.

I find when employing an adhesive between the metal and the foil that the non-absorbent char- 35 acteristic of the foil is of advantage in that the metal leaf adheres to the foil more satisfactorily than when employing a backing or mounting such as the paper, for instance, commonly employed in this art. 40

In Fig. 3 the foil F is in ribbon form as distinguished from a sheet. The metal leaf G is mounted directly on one side of this foil and the surface of this metal leaf is coated with the size 1-1 as in Fig. 1.

In Fig. 4 the foil F is in ribbon form the surface of this foil being coated with an adhesive I for attaching the leaf G in ribbon form to the foil, the surface of the leaf G being coated with a suitable size H. 50

It will be evident that in all the embodiments of my invention above described the metal leaf is mounted on a backing of metal foil, so that this backing will not be destroyed as in the case of paper mountings, but can be reclaimed which of course is an economic advantage.

What I claim is:

1. An article of manufacture for heat embossing comprising in combination aluminum foil, metal leaf, and an adhesive for securing the metal leaf to the surface of said aluminum foil.

2. An article of manufacture for heat embossing comprising in combination a carrier sheet of thin aluminum foil, metal leaf, an adhesive for securing said metal leaf to the surface of said foil, and a coating of size on the outer surface of said metal leaf.
