- the ring thus produced constitutes the inner ring and is inwardly concaved.
- the chuck illustrated is designed to form the outer ring or band into cross-sectional concave-convex form and it also consists of two sections 40 and 41, the former being secured to the head 24 by screws 2-9.

- the section 41 is in the form of a ring provided with an annular shoulder 47 and a curved portion 48 extending from the shoulder 47 to the inner face of the section.
- the two curved portions 43 and 48 will, when the two sections are in engagement form an interior concave groove in the chuck, the curvature of said groove being such as is necessary to give the desired cross-sectional shape to the outer ring.
- the operation in this case is substantially the same as described with relation to Fig. 1 except that the ring is placed within the chuck instead of outside it, and the burnishing tool must be so formed that it may be inserted through the central opening of section 41 to apply pressure to the ring,
- the open frame In order to support and press the section 41 towards the section 40 means must be employed which will not interfere with the manipulation of the burnishing tool and which will permit the free rotation of the chuck without rotating the supporting and pressing device.

MECHANISM FOR MANUFACTURING TUBULAR BRACELETS AND SIMILAR ARTICLES.
Specification of Letters Patent.
Patented July 9, 1907.
Application filed November 22,1906. Serial No. 344,544.
To all whom it may concern:
Be it known that we, MoRRIs MILLER and EDWARD MORRIS, citizens of the United States, and residents of the borough of Manhattan, New York city, and Newark, New Jersey, have invented certain new and useful Improvements in Mechanism for Manufacturing Tubular Bracelets and Similar Articles, of which the following is a specification.
This invention relates to mechanism for manufacturing tubular bracelets or similar articles of jewelry.
Heretofore, so far as we are aware, in the manufacture of hollow or partly filled bracelets and kindred articles of jewelry it has been the practice to take a piece of metal tubing ofthe desired length, fill it with sand or like material and then bend the same around a suitable former to give'it the desired shape, such as circular or oval and then, after discharging the sand, solder or otherwise secure the two ends together. Instead of using metal tubing, I propose to use two rings or bands made from strips of flat metal which are caused to assume a concave-convex form in cross-section in opposite directions, after which one ring is slipped over the other and the edges of the two rings soldered together.
Our present invention relates to mechanism for forming the flat rings into concavo-convex shape in cross-section.
We will describe preferred forms of mechanism embodying our invention and then point out the novel features in claims.
In the accompanying drawings:Figure 1 is a side elevation, partly in section of a machine for forming what will be termed the inner ring, the fiat metal ring being in position in the two part chuck, and the two parts of the chuck being separated. Fig. 2 is a similar view of a portion of the machine showing the two parts of the chuck in engagement and the ring in concavoconvex form. Figs. 3 and 4 are sections on the line :t-x of Fig. 2 looking to the left and right respectively. Fig. 5 is a view of a strip of metal. Fig. 6 shows the strip formed into a flat ring. Fig. 7 is a side elevation,
partly in section, showing a machine with a chuck for forming the outer ring. Figs. 8 and 9 are sections on the line y-y of Fig. 7, looking to the left and right respectively. Fig. 10 is a side elevation, partly in section, showing a modification of the machine shown in Fig. 7. Fig. 11 is a section on the line 2-2 of Fig. 10 looking in the direction of the arrow.
Referring now to Figs. 1 and 2, 20 indicates a lathe spindle journaled in a bearing 21 and provided with pulleys 22 fast thereon whereby the spindle may be rotated by a belt 23 which will be driven from any suitable source of power, not shown. A head 24 is detachably connected to the spindle 20 in any suitable manner, as for example by the screw connection shown.
The chuck employed comprises two sections or parts, indicated respectively by 25 and 26 which, while having similar peripheral form are oppositely disposed. Each, preferably, has a peripheral shoulder 27 near its outer face and a downwardly and inwardly curved peripheral portion 28 extending from its shoulder to its inner face and these curved portions will, when the inner faces of the two parts are together, form a concave groove 28 in the periphery of the chuck, the curvature of such groove being such as may be necessary to give the desired shape to the ring. It will of course be obvious that saidgroove may vary in depth according as it is desired to have the finished bracelet or ring cylindrical or oval in cross-section.
The section 25 is detachably secured to the head 24, as for example by screws 29, and is provided with a plurality of holes 30 to receive pins 31 projecting from the inner face of the section 26, and which are designed to insure that the two sections fit accurately together and form a smooth continuous groove 28.
' A strip of metal 32 of the desired length is formed into a ring 33 by soldering or otherwise securing its ends together and this ring is first slipped on the section 25 after which the section 26 is inserted in the opposite side of the ring and the pins 31 entered into the holes 30 as clearly shown in Fig. 1. It is necessary to provide some means to support the section 26 and also to force it gradually toward the section 25 as the ring is gradually formed into the desired cross-sectional shape, and while various means may be employed for this purpose, the mechanism illustrated in Figs. 1 and 2 has been found efficient. As shown a sleeve 34 is supported to slide longitudinally in a standard or support 35 which may be adj ustably or otherwise supported on the lathe bed. A screw 36 works in the sleeve and is provided at its outer end with a hand wheel 37. The screw is held against longitudinal movement and consequently when the screw is rotated the sleeve will move longitudinally. The outer end of the sleeve is provided with a tapering bore to receive a pin 38 the outer end of which is conical and fits in a conical recess in a hardened plate 39 secured to the outer face of the section 26. The point of the pin 38 is intended to be in line with the axial center of section 26 so that when the sleeve is moved outwardly the section 26 will move truly toward section 25.
When the parts are in the position shown in Fig. 1, the lathe spindle will be caused to rotate and pressure is applied to the ring 33 by means of a burnishing tool of proper form and the section 26 be moved gradually toward section 25 until the two sections are engaged when the ring will have been bent into cross-sectional concavo-convex form, as clearly shown in Fig. 2, corresponding to the shape of the groove 28 The ring thus produced constitutes the inner ring and is inwardly concaved. I
Referring now to Figs. 7 to 9, the lathe spindle and its head are the same as heretofore described. The chuck illustrated is designed to form the outer ring or band into cross-sectional concave-convex form and it also consists of two sections 40 and 41, the former being secured to the head 24 by screws 2-9. The section 40 is cored out and has an internal annular shoulder 42 and a curved portion 43, extending downwardly and outwardly from the shoulder 42 to the inner face of the section. It is also provided in the annular portion 44 which surrounds the curved portion with a plin'ality of holes 45 to receive pins 46 projecting from the inner face of section 41. The section 41 is in the form of a ring provided with an annular shoulder 47 and a curved portion 48 extending from the shoulder 47 to the inner face of the section. The two curved portions 43 and 48 will, when the two sections are in engagement form an interior concave groove in the chuck, the curvature of said groove being such as is necessary to give the desired cross-sectional shape to the outer ring. The operation in this case is substantially the same as described with relation to Fig. 1 except that the ring is placed within the chuck instead of outside it, and the burnishing tool must be so formed that it may be inserted through the central opening of section 41 to apply pressure to the ring,
with a result that the ring will be concaved outwardly or away from its center instead of inwardly or towards its center as in the case of the inner ring formed by the machine illustrated in Fig. 1.
In order to support and press the section 41 towards the section 40 means must be employed which will not interfere with the manipulation of the burnishing tool and which will permit the free rotation of the chuck without rotating the supporting and pressing device. For this purpose an open frame is supported to be moved toward and away from the section 40 and balls are interposed between said open frame and the section 41 to minimize friction. As shown in Fig. 7 the open frame consists of two arms 49 extending from a bar 50 which is provided with a tapered pin 51 which fits tightly in a socket in a plug 52. This plug which is angular in form exteriorly fits in an opening in a sleeve 58 sup ported to slide in a bearing 53 adjustably or otherwise supported on the lathe bed. A hand operated screw 54 serves to reciprocate the sleeve. A spring 55 is interposed between a flange on the outer end of theplug and' the outer end of the sleeve and tends normally to press the open frame and section 41 toward section 44. Each arm 49 is bifurcated at its outer end and a ball 56 is pivotally supported by screws 57 fitted in the two limbs, and these balls are adapted to engage the outer section 41 and when the sleeve 58 is moved outwardly will force the section 41 toward section 40 and at the same time permit free rotation of the chuck.
Referring to Figs. 1Q and 11, the open frame is in the form of a ring 60 carried by an arm 61 projecting upwardly from a slide 62 supported in a block 63 adjustably or otherwise supported on the lathe bed. A hand screw 64 fitted in the block 63 is employed to force the ring 60 toward the section 40. A series of balls 65 are interposed between the ring 60 and the section 41 to permit the chuck to rotate freely while the section 41 is being pressed toward section 40. To prevent the balls being displaced the ring 60 may be detachably connected to the section 41 by means of a clip 66 so that the ring 60 and section 41 may move together. Other means may, however, be employed to hold the balls in place on the ring 60 in which case the clip 66 may be dispensed with and the ring and section be movable independently of each other.
It may sometimes be desirable to employ an open frame similar to those shown in Figs. 7 and 10 instead of the pin 38 shown in Fig. 1, for forcing the section 26 toward section 25.
It is to be understood that the foregoing is a description of preferred embodiments of the invention but such invention is not thereby limited to the precise details of construction illustrated and described.
Having described the invention, we claim:
1. In mechanism for the purpose specified, a chuck comprising two sections each having an annular laterally curved portion extending from its inner face toward its outer face and said curved portions forming a concave groove when the inner faces of the sections are in engagement, a rotary member to which one of the sections is attached, lneans for supporting and guiding the other section in its movement toward the attached section, and adjustable means for moving the guided section into contact with the attached section while permitting the chuck to rotate freely.
2. In mechanism for the purpose specified, the combination of a rotary head, a chuck comprising two sections, one of said sections having guide pins and the other holes for receiving said pins, means for connecting one of said sec tions to the head, and adjustable means for engaging the section to force it into contact with the other section connected to the head while permitting the chuck to rotate freely.
3. In mechanism for the purpose specified, the conibina tion with a rotary head, a chuck comprising two sections each having an annular laterally curved portion extending from its inner face toward its outer face, one of said sections having guide pins and the other holes to receive said pins, means for connecting one of said sections to said head, and adjustable means for engaging the outer face of the other section to force its inner face into engagement with the inner face of the section connected to the head while permitting the chuck to rotate freely and thereby cause the said curved portions of the two sections to form a symmetrical concave groove.
4. In mechanism for the purpose specified, the combination of a rotary head, a chuck comprising two sections re spectively shaped to form a concave groove when their inner faces are engaged, one of said sections having guide pins projecting from its inner face and the other-holes to receive said pins, means for securing one section to the retary head, an open frame movably supported to engage the outer face of the other section, and balls interposed between the frame and section.
