WATCHCASE-BOW.
Specification of Letters Patent.
Application filed July 27, 1909.
Patented Sept. 2%, 1919.
Serial No. 509,864.
To all whom it may concern:
Be it known that I, BERNARD LEVY, a citizen of the United States, and a resident of Riverside, in the county of Burlington and State of New Jersey, have made and invented certain new and useful Improvements in VVatchcase-Bows, of which the following is a specification.
My invention relates to an improvement in watch case bows, and more particularly to what is known and commonly termed by the trade as a Swiss bow, that is, a bow comprising a bow proper and a bar formed on each of its two free ends. Heretofore it has been the practice to construct these bows of solid gold, or from solid gold wire, even though intended to form a part of, or be employed in connection with watch cases made of plated or filled gold, as it has thus far been found impossible to construct them of filled gold, or of filled gold wire and provided with an unbroken outer coating, covering or envelop of gold or precious metal, the outer ends of the horizontal bars being left raw, and exposing to view the base metal of which the bow was partially made.
The object of my invention is to construct a bow of this character of filled gold, or gold filled wire, having its entire outer surface covered or protected with a continuous or unbroken outer skin of precious metal, with the exception of the extreme ends of the bow which are contained within and concealed by the Watch case pendant with which the bow is assembled in the completed watch case, and with such and other ends inview, the invention consists of a bow, as hereinafter described and specifically pointed out in the claim.
In the accompanying drawings, Figure l is a view in elevation of a piece of gold filled wire from which the bow is constructed. Fig. 2 shows the result of the first operation. Fig. 3 shows the result of the second operation wherein the metal is coaxed or partially struck up into the form of ears. Fig. 4 is a similar view showing the result of the third operation, and whereby the ears are struck up half full. Fig. 5 shows the result of the next operation, whereby the ears are completely formed. Fig. 6 shows the result of the next operation, whereby the excessive metal at the ends of the bow is cut away. Fig. 7 shows the bow bent into final shape. Fig. 8 shows the bow after being planished and stiffened. Fig. 9 is a sectional view taken on the line 9-9 of Fig. 7. Fig. 10 is a similar view of the same taken on the line 1010 of Fig. 8. Fig. 11 is a longitudinal sectional view, taken on a vertical plane through the bow illustrated in Fig. 8.
As before described, my improved bow is constructed from a piece of gold filled wire A, of proper length, and suitable diameter, and which is bent into the form of a bow B, as illustrated in Fig. 2. By means of suitable dies, the metal comprising the ends of the bow is gradually forced backward to form the slight projection C, as illustrated in Fig. 3, then into the partially formed ears D, as illustrated in Fig. a, and finally into the completely formed ears E, illustrated in Fig. 5, these several operations somewhat enlarging the extreme ends of the wire, as illustrated at F. These enlarged ends are then cut off, as illustrated in Fig. 6, thereby completing the formation of the bars Gr, which as well as the wire or bow proper A, are completely protected and covered by an unbroken outer skin or covering of precious metal, with the exception of the extreme ends H. The bow is then bent into proper form, as illustrated in Fig. 7, having the cross section as illustrated in Fig. 9. If desired, the bow is then given the cross section as illustrated at A, Figs. 8 and 10, or any other desired shape in cross section to harinonize with the style or decoration of the watch case with which it is to be employed.
As a result of the above described method, I have produced an article having new and novel characteristics, that is, a bow made from a single piece of gold filled wire or a wire having a core of base metal A and an outer covering of precious metal A all those parts or portions of which bow that are exposed to view, being covered or protected by the unbroken outer skin or envelop of precious metal A and having the shape, contour and appearance of a bow made from solid gold wire. These bows constructed as described, I have found in practice will effect a great. saving in the manufacture of watch cases, as the substitution thereof for the solid gold bow heretoered with precious metal With the exception of the inner ends of said bar, substantially as described.
Signed at Riverside in the county of Burlington and State of New Jersey this 20th day of July A. D. 1909.
BERNARD LEVY.
