Our present invention relatesto'the `art `jewelry manufacture, and .has particular reference to .themanufacture of ornamentalstock for bracelets, anklets, girdles, and other articles "of The ornamental stock now in use include stock formed with prismatic depressions, preferably formed by stamping the stock'with diamonddies, Vwhereby the stockv ance ofjewel inserts; This sto-ck when used for i bracelets, for example',

the separate rings-being joined or secured togetherbylmeans' of a connectingV band orY the like. .y

Wehavefdevised aA novel method andapparatus for producing the-novelstock in theform =fof alcontinuous metal helix, of any desired length; andwe' have devised amanufacturing arrange- 'mentito controlvthespacingvof the helix turns,

whereby the turns may be close, or may be `unito permit the insertion of formly spacedapart van c'irnanie'ntalV helix of differentmaterial, such as for example catalin of differentc'olors.

Tothis end, wefha've improvedV the process of manufacturing ornamental helix,l and Vwe have improved the apparatus therefor, :so as-to utilize soft metal wire, which is hardened and elongated bylw'orking,`whereb`y a `novel product consisting of a` continuous ornamental metal helix of `pre- 'determined 'size and spacing is automatically obtained. u j i With -thef above,` and vother objects and advantageous features infVeW, our invention consists of a novel process, and a vresulting novel product, as more fullyfdisolosed inthe detailed `descriptio-n following in' conjunction with the accompanying drawings, and as more specifically denedV in the claims appended Ithereto.

Y. Fig. 9 is adetail Referring to the drawings, the novel apparatus is generally similar to .standard punchor'impressing mechanism, and includes a base l adaptedV to be mounted on a bench or'the like, a body il receiving an anvil fixture, and a head I2 containing the usual plunger operating mechanism, r,the `headA .1.82. housing a g reciprocating plunger i3. A power pulleyld, see Fig. 2, rotates theusual shaft L of the plunger operating mechanism, and a pulley' lruis keyed' on the plunger shaft to` impart rotativemovement toV a fixture pulley I 1, Y'asby albeit lfwhereby the `fixture shaft VI9 is rotatedv in timed relation to thereciprocating movement of. thefplunger,

Theanvil fixtureZQ, see Fig. 2,7 is rinourltedon the body H in operative engagement with the forward end of the `fixture shaft, and a guide shaft 3U is positioned on the rend of the fixture shaft to receive the completed helix as it leaves the anvil xture. y Referring nowto Figs. 1, 4, and 6, the anvil fixture 29 has an anvil 3| rotatably mounted thereon and adapted to be keyed to the shaft perspective view showing the impresseddesign :'l l Y I9, whereby the anvil is positively rotated. A

gear 32, see Fig. 5, is secured to or formed integral with the anvil, and rotates an idler 33 for imparting positive motion to the gears 34, 35, secured to or integral with a lower feed roll 36, and an upper feed roll 31 which is mounted in a swinging arm 38 and is resiliently pressed towards the lower feed roll by a spring 39, the spring being locked on an adjusting bolt 40 which is threaded in the fixture body and.p9,Sses through a suitable bore 4| in the swinging arm. The lower feed roll is preferably knurled to provide a firm grip on the wire, and may be roughened or embossed to rmly grip the wire or to impress an attractive design on the inner surface thereof. A horizontal guideway 42 is provided in the fixture between the anvil and the feed rolls.

Two guide rollers 43, 44, see Fig. 4, receive the impressed wire after it leaves the anvil, and an adjustable forming roller 45 then guides the wire onto a forming plate 4S having curved elevations and depressions which cooperate with the forming roller to set the curvature of the wire, the vertical setting of the adjustable forming roller determining the diameter of the formed helix, and the lateral setting of the forming roller determining the spacing of the formed coils. The forming roller 45 is rotatably mounted in an arm 41, see Figs. 4 and 7, which is devtachably secured to the fixture body, and may be shifted vertically by removing and resetting a pivot pin 48, on which it may also be adjustably swung, see Fig. 7, in order to secure a predetermined uniform spacing between coils, as indicated in Fig. 8.

The operation of the mechanism The .operation is best disclosed with reference to Figs. 4, 5, and 1; the metal wire W is received lin the'fixture between the two feed rolls, and is vpositively fed to the anvil, at which point it re- 'being dependent on the vertical adjustment of Y the forming roller and the coil spacing being de- Apendent; on the lateral adjustment thereof.

Although the stock may be with any desired design, the .most suitable imprints are of diamond formation,!and the preferred type is illustrated infFig. .9, and is in the form of an inverted 'truncated pyramid having a vrectangular base, 'a rectangular top, and sloping faces between the corresponding sides of the'base and top.

The above described operation, using a rotary anViL'punches the impression on the stock at the start of the curve, and thus produces an impression in which the design is not distorted and the brilliancy is not effected Vby the actual cuwingnauch as would resultwhen theimpressed stock is wound on an arbor. The brilliancy and clean punch effect of the impression in the final helix is thus unimpaired.

It is thus evident that the invention comprises a novel process in that a dead soft metal wire is `worked to obtain a desired impressing and to harden the wire, and is then bent into a spiral of predetermined diameter; a novel'apparatus in that the mechanism is adjustable to gauge the impression and to set the spiral obtained for diameter and for spacing; and a novel product in that .an ornamental spiral of desired width and spacing and of springy metal is obtained.

While we have described a specific constructional embodiment of our invention, it is obvious that desired changes in the arrangement and the size of the parts and in their function and operation, may be made without departing from the spirit and the scope of the invention as defined in the appended claims.

We claim:

1. A helix of hardened resilient material lhaving indented ornamentation on the outer surface thereof.

2. A helix of hardened resilient material `having indented ornamentation on the outer surface thereof, the coils of the spiral being uniformly spaced apart.

3. A hardened resilient stock for use in making ornamental jewelry, having adjacent impressions of truncated rectangular pyramidal shape.

4. In the manufacture of ornamental jewelry,

- the steps of hardening a metal wire by indenting the lupper part while holding the sides and the lower part against spreading, and winding the hardened wire into a helix.

5. In the manufacture of ornamental jewelry, the steps of hardeninga metal wire by indenting the upper part while holding the sides andthe lower ypart against spreading, and winding the hardened wirevinto a helix of predetermined diameter.

6. In the manufacture of ornamental jewelry, the steps of hardening a metal wire by indenting the upper part while holding the sides and the lower part against spreading, and winding the hardened wire into a helix of predetermined diameter and predetermined spacing between vthe coils thereof.

7. A helix of hardened resilient material having indented ornamentation on the outer surface thereof, the sides and the lower surface of said material being substantially smooth.

8. A helix of hardened resilientmaterial having indented ornamentation on the outer surface thereof, the coils of the helix being uniformly spaced apart, the sides and the lower surface of said material being substantially smooth.

9. A hardened resilient stock for use in making ornamental jewelry, havingadjacent impressions of truncated rectangular pyramidal shape, .the sides and the lower surface of said stock Ybeing substantially smooth.
