H0 HODEL.
PRQCESS f)?" in SPECIFXCATION forming part l. l ElNGSE of Letters Patent Ito. T 64362, dated July 12, 196%.
Application filed October 12, 1863. Serial 176,640. (i'lo specimens.)
To all wit/mt it nwzyconccrn:
Be it known that i, Fulani: Ivlossnnno, a rcsident of the town of Attlehoro, in the county of Bristol and State of Massachusetts, have invented certain new and useful improvements in Processes of .llalring rletal Rings; and i do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.
This invention pertains to a new method or process of making rings, and has for its ohject the construction of ornamental lingerrings, as well rings for various other purposes, by drawing or swaginm To produce the rings in this manner, steel; is rolled into sheets of the required thiclc'ness, from which circular hlanl ts are cut and swnged by a series of operations into a ring of the desired form and size, thus producinga continuous band from one solid piece of material without a joint, with its surface and c: hardened, finished, and polished ready [or service without the necessity of turning or grinding, a. now the case in finishing it linger-ring made in the ordinary manner.
The invention consists of novel features and parts and combinations of the same, as will be fully escrihed hereinafter and then pointed out in the claim.
A practical embodiment of the im'cntion is presented in the accompanying drawings,
forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.
Figure 1 represents the blank as cut from the sheet-stock. Fig. 2 represents the blank in place on the die with the plunger in position above it. Fig. 3 represents the plunger ashaving descended and forced the stool; into the die. Fig. I is a sectional view of the cup shaped piece formed from the l)l()Cl Fig. 5 illustrates said cup-shaped piece in die ith the cutter-plunger ready to descend and punch out the hotton Fig. 6 shows the cup with the bottom punched out. Fig. 7 illustrates the forming-dies as drawn apart with the hlau'u dotted in position to he struck up in the desired form. Fig. 8 shows said forming-dies closed with the ring" in position therein swag-ed into shape. Fig. 9 shows the finished ring in section swaged into an oval or convex form on its outer periphery. Fig. 10 is a view in elevation of a finished ring.
Referring to the drav-Iings, A is the circular blank or disk, which may he struck froi'n sheet metal previously prepared in any suit ahle manner and mode to the desired The material used may he gold, silver, brass, steel, or any other suitable metal or materialwhich nray he cut, drawn, and sweg'ed into the desired form. The material after beingcut'to the desired size and shape is "forced hy the plunger ll into the die i), the end of said plunger B being reduced in diameter an amount double the or thickness of the material to' he worked. l ien it is desired to make a ring" whose periphery is in oval form like that illustrated in i 9, shoulder where the reduced portion =1) joins the larger portion of the plunger is rou out or lilletod on a large radius, which is cssary for turning or forcing out the uppedge I of the blank it the desired amount s the material is r'orccd into the die, as illustrated in Fig. 3. lhe end of the plunger C is also rounded about its lower edge on a radius suliicient to draw and round up the material on the outsi.
'l he eliect oi this o 'ieration is to crowd or con dense the metal at the points 1' and 6, making the metal ct these points of maximum hardness. The nextoperation that illustrated in Fig. The work i2) is placed in the proper die F made to receive it. The plunger (l is forced down through the work, punching out the bottom. of the cup, which bottom falls in the form of a small disk, leaving the work in the form of a ring H. (See Fi 6.) This punching operation'does not materially alter the condensed or hardened condition of the metal ate. The ring-blank thus provided has its lower end rounded in etc from its periphery to-its lower inside edge on the arc of a circle which es lo the desired radius c on its lower-edge c,asalsoillustrated in Fig.
I rounded off at but on a reversecurve to that ,-cut from the sheet stock and swaged into the tends substantially one-halt the width of the l ring. The upper edge of this ring is also of the lower edge, which curve extends from the inside circle to the upper outside edge and extends down into the ring approximately onehalf its width. The ring is nextplaced in the forming-dies, (illustrated in Fig. 7,) said dies being made in two parts J and K, with a removable center post M through the lower die. These dies aretboth'eupped outinto the form in which the'periphery of the ring is to be swaged, and as the dies are brought together the upper edge of the metal in the ring is turned over or drawn in against the post M into the form illustrated at it in Fig. 8, the condensed or hardened condition of the metal at said edge remaining unaltered as a result of this last step. The dies are then separated, the center post withdrawn, and the ring is turned out with aeon vex periphery, the form illustrated in Figs. 9 and 10.
'It will be noted that the blanks A may be form of cup 1 in one operation, if desired, without departing from the spirit and scope l of my invention.
The advantages of my improved method of making rings will be apparent to those skilled hard anddurable.
dies which act on the edges of the ring-blank in the manner described the metal in said edges is closely condensed, whereby the edges of the finished article are made extremely This is of particular advantage in making rings of very thin stock, in which it is absolutely essential that the edges be of maximum hardness to withstand wear.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, v,
The method of forming rings, consisting in drawing a blank into the form of a cup and simultaneously swaging or forcing the upper inner edge outward, and drawing the lower outer edge into a rounded form, all in the same operation; punching the bottom from said cup, whereby a ring-blank. having tapering edges is secured; and finally forcing said upper edge inward, whereby a plane-convex ring is formed.
In testimony whereof i have hereunto set my .hand this 7th day of October, A. I). 1903.
