JEWELER'S STOCK Filed Oct. 26, 1960 K F'GS 7 Fl.G.6
INVENTOR. PHILIP F. LEACH ATTORNEYS United States Patent 3,063,137 JEWELERS STOCK Philip F. Leach, Attleboro, Mass., assignor to Leach & Garner Company, a corporation of Massachusetts Filed Oct. 26, 1960, Ser. No. 65,171 Claims. (Cl. 29-183) This invention relates to jewelers stock such as may be used for making up different articles of jewelry either in the form of a compact, cigarette case, or other places where sheet stock may be used for a decorative effect.
One of the objects of this invention is to provide a new and different appearance of the surface of jewelers stock.
A more specific object of the invention is to provide a so-called plaid appearance which will have the effect of stripes running in directions at right angles to each other.
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:
FIGURE 1 is a perspective view of a portion of the jewelers stock before it has been rolled to impress upon it the lines to give it the plaid efiect;
FIGURE 2 is a perspective view of a roll used upon the stock shown in FIGURE 1;
FIGURE 3 is a diagrammatic view illustrating the surface of the roll which is used;
FIGURE 4 is an end view of a fragmental portion of the roll;
FIGURE 5 is a perspective view of a portion of stock which has been rolled to provide the plaid effect which is the subject of this invention; and
FIGURE 6 is an edge view of a fragmental portion on an enlarged scale.
In proceeding with this invention, I have laid in edge to edge relation different colored strips of metal, and I then roll or impress upon these strips of metal groups of lines with spacings between the groups, these lines running at right angles to the lengthwise extent of the different colored gold strips, and this impression may be made by rolling or any suitable impression to secure these lines.
With reference to the drawings 10 designates one strip of metal and 11 another strip of metal which is shaded to indicate a contrasting color, while strip 12 may be the same as strip 10 or still a different color, and strip 13 may be of the same color as strip 11 or still a difierent color from 11. These strips are in ribbon-like form and of any convenient thickness which is usually much less than the width of the strip, and they are laid in edge to edge relation with a soldering along'the lines 14, 15 and 16. In some cases this group of strips may be assembled in edge to edge relation by attaching them to a base plate such as 17 shown in FIGURE 5, in which case the edge to edge relation may be secured by soldering the under surface of each of the strips to the base plate 17 as along the line 18. These strips may be of a thickness greater as 20 with spaced than their finished thickness if desired and may be rolled down after they are secured together at their edges or when a base plate is used such as 17 the strips are secured to the base plate, and both plates together may be rolled down to a finished thickness. In either event by the reduction in thickness the different colored strips will maintain their same relationship either to each other or to the base plate when such rolling occurs.
As a further and finishing step, the different colored strips such as 10, 11, 12 and 13 are then impressed with a plurality of parallel lines 19 arranged in groups such plain surfaces 21 between the groups, the spacings 21 may be all the same or of varying widths, but where they are of varying widths, the pattern will repeat as the ornamentation is progressed lengthwise of the strips.
This group of shallow lines 19 provide a suflicient interruption in the reflected light from the surface so that together with the different colorings of the metal, a generally plaid eflFect is provided on the surface of the metal which is unique and occurs by the impression of the lines at right angles or substantially at right angles of the length of contrasting different colors of strips provided.
These lines 19 may be placed in the surface of the work by any suitable tool. One form of tool is illustrated as a roller 23 having ribs 24 in groups at intervals or spaces 25 around its surface, these ribs running lengthwise and parallel to the axis of the roller.
1. Jewelers stock comprising ribbons of contrasting colored metal laid edge to edge in extended lengths and groups of parallel indented lines extending at right angles to the length of ribbons with spaces between the group to provide a plaid effect.
2. Jewelers stock as in claim 1, wherein the groups of lines and spaces between the groups provide a repeat pattern along the length of the stock.
3. Iewelers stock as in claim 1, wherein the groups of lines and spaces between the groups are substantially equal.
4. The method of providing a plaid effect on jewelers stock comprising fixing contrasting colored strips of metal in edge to edge relation, and impressing groups of lines into said strips at right angles to their length with the groups at spaced intervals.
5. The method of providing a plaid efiect on jewelers stock comprising fixing contrasting colored strips of metal in edge to edge relation, and rolling groups of lines into said strips at right angles to their length with the groups at uniformly spaced intervals.
