Jan. 19, 1965 G. H. BARNEY METHOD Foa PRoDucING JEwELERs sTocx Filed May 21, 1962 United States Patent O 3,165,824 METHOD FR PRDUCING IEWELERS STCK Greenliet Haskell Barney, Attleboro, Mass., assigner to Leach & Garner Company, a corporation of Massachusetts Filed May 21, 1962, Ser. No. 196,128 4 Claims. (Cl. 29-411) This invention relates to a method for producing jewelers stock of the sort that would have some pattern effect.

Heretofore, there has been provided certain sorts of jewelers stock which may be of precious metals, such as gold, and which would have a variegated appearance by reason of chunks of metal of one color being dropped into a metal of a different color which was in the uid or liquid state but near solidication so as to provide a var-igated or marbleized eifect. This sort of an effect, however, is one which could not be reproduced because of the haphazard operation of dropping solid chunks-into molten metal which could never be exactly repeated because the method of production did not lend itself to exact reproduction, there being no particular control of the dropping of the solid chunks into the molten mass.

One of the object of this invention is to provide a piece of jewelers stock in which the pattern may be controlled so that it may be reproduced at will `and a method of readily producing the same. v

Another object of the invention is to provide a method for producing jewelers stock which may have a large variety of patterns formed therein by predetermination or calculation as to what the finished result should be.

Another object of this invention is to provide a method for producing a highly decorative piece of stock which may be made up into various articles of jewelry as occasion may require.

With these and other objects in view, the invention consists of certain novel features of construction as will be more fully described and particularly pointed out in the appended claims.

In the accompanying drawings:

FIG. 1 is a perspective view of a number of relatively thin pieces of material secured together in face to face relation with each of the strips of different color and none of the two colors of material being in contact with one another, thus providing a contrasting relation across the edges and ends ot the composite assembly;

FIG. 2 is a perspective view illustrating a slice taken off the yassembly at right angles to the faces of the strips showing lengthwise stripes formed in the plate thus provided;

FIG. 3 shows a plurality of plates such as shown in FIG. 2 superimposed one on the other in such a relationship that the stripes of one color do not come in face to face contact with the stripes of another color, thus providing a sort of checkered pattern effect on the ends of the assembly;

FIG. 4 is a plan view of a slice taken parallel to the end face shown in FlG. 3 after the slice has Ibeen rolled in the direction of the arrow shown in FIG. 4; and

FIG. 5 is a view similar to FIG. 4 showing a slice after it has been rolled in the direction of the arrow shown in FIG. 5.

In proceeding with this inventoin, I have assembled 3,165,824 Patented Jan. 19, v1965 two colors are in contact with each other, thus providing at the end of the assembly different colors in somewhat of a checkerboard or plaid effect. At this point a slice maybe taken parallel to the end face providing a second plate, and this second plate thus formed may be further treated by rolling which will distort somewhat the checker effect which is provided, the distortion being different depending upon the different direction of reducing rolling which may occur and the number of passes through the rolls. Y

With reference to the drawings in FIG. 1, there is a rectangular strip ot red gold 1G, a rectangular strip of green gold 11 and a rect-angular strip of white gold 12 shown in face to face contact along the lines 13 and 14 which repeat in these three colored strips so `as to pro-` FIG. 1 so as to provide a plate, designated as 17, in

FIG. 2, having the portions of the strip material 10', 11 and 12 in the repeats as they `are shown. In this particular plate the -red gold 10 is on one outside edge, while the white gold 12 is on the other outside edge. such block as shown in FIG. 1 may be provided in which the green gold 11 may -be on the outside edge at one end, and the red gold 10 on the other outside edge as shown in plate 1S in FIG. 3, while the plate shown at 19 in FIG. 3 would be plate 17 turned upside down.

These plates 17, 18 and 19 illustrate the red portion 16)' as contacting the green portion 11 in the plate 13, or in other words each one of the strips is moved one space or one thickness of the strip to the left with reference to plate 17 above described. Plate 19 shows the strips 12 as directly below the green strip 11 of plate 1S and thus the strips being moved two spaces to the left with reference to the plate 17 or one space to the left with reference to plate 1S. The further plates 2t?.

. 21 and 22 are a repeat of the strips 17, 18 and 19. The

plates yare secured together bya thin film of solder, thus slightly` increasing the total dimension of the assembly.

In furtherance of the invention, a slice will be takenoti either along the line parallel to the end face and at right angles to the faces of the strips such las 30 or -a line parallel thereto which is so as to provide a second plate of the pattern desired. A plate so formed may be rolled down to the desired thickness, and the general pattern effect will remain substantially the same although it will become somewhat distorted depending upon the direction of rolling. Thus, if rolling is in the direction of the arrow 35 as shown in FIG. 4, each one of the blocks of colored material will become Wider in the direction of the arrow in the inished rolling, or if the rolling is in the direction of the arrow 36 as shown in FIG. 5, each one of the blocks will become longer slightly than it was previously as shown in the View of FIG. 5. Likewise, if there is a diagonal rolling, there will be a distortion formed in the form of a rhomboid for each of these dierent rectangles which are heretofore shown. By the predetermination of the rolling where there is some distortion, that is, knowing the amount that the strip has been reduced, the amount of elongamost any pattern may be predetermined and formed in an assembly of different colored golds. Such patternsmay take the form of letters to make a certain word or other designs which may be lfound desirable.

By keeping account of the `sizes of material used and the reduction by rolling yand direction of rolling in any pattern, the pattern may be accurately reproduced by repeating the operation.

I claim:

Another 1. The method of providing a reproduceable pattern effect in jewelers stock which comprises assembling and securing contrasting colored strips of metal in face to face relation to provide contrasting ends and edges, severing at an angle ,to the `faces to provide a plate with generally contrasting parallel surface stripes and end areas, assembling and securing `a plurality of such plates in face to face contact with the colored metals at least partially out of registry to provide a pattern in an end relation of the plates.

2. The method of claim 1 plus the severing of the rassembly at an angle to the faces to provide a second plate with a pattern therein.

3. The method of claim 1 plus the severing of the assembly at an angle to the faces to provide a second plate With -a pattern therein and rolling the plate toY distort the pattern.

4. The method of providing a reproduceable pattern effect in jewelers stock which comprises assembling and securing contrasting colored strips of metal in face to face relation to provide contrasting ends and edges, severing at an `angle to the vfaces `to provide a plate with generally contrasting parallel surface stripes and end areas, rolling the plate to distort the stripes, assembling and securing a plurality of such rolled plates in `face to face contact with the colored metals at least partially out of registry to provide a pattern in an end relation of the plates.
