Specification of Letters Patent.

Application filed May 5, 1910.

Serial No. 559,641.

To all whom it may concern Be it known that I, DAMON A. lVnrrn, a citizen of the United States, and resident of Attleboro, in the county of Bristol and State of Massachusetts, have invented a new and useful Mode of Forming an Integral Shank and Bean for Buttons, Studs, and the like, of which the following is a specification.

The object of my invention is to form from a flat metal blank, without annealing, a durable, efficient and inexpensive tubular Y-shaped shank and hollow seamless bean integral with each other, and which will prevent the button or stud from turning in the button hole of the cuff or garment in which it is worn. I accomplish this in the manner hereinafter described, and illustrated in the accompanying drawings in which,

Figure 1 is a perspective view of a blank which I cut from a strip of metal. Fig. 2 is a plan view of same after the first operation. Fig. 3 is a side elevation in perspective of Fig. 2. Fig. 1 is a section of the same. Fig. 5 is a plan view showing the shank and bean integral therewith, the shank having been reduced in cross section to form a neck adjacent the bean. Fig. 6 is an elevation of the same. Fig. 7 is a section of the same taken on line 77 of Fig. 8. Fig. 8 is a plan view of the same part shown in Fig. (5. Fig. 9 is a plan view showing the shank flattened into oblong form. Fig. 10 is a plan View showing the shank flattening carried farther to form tubular passages at opposite sides of the shank. Fig. 11 is a section taken on line 1111 of Fig. 10. Fig. 12 is a side elevation of the shank and integral bean before it is shaped into its finished form. Fig. 13 is an elevation of the finished shank and bean.

I form the shank and bean in manner substantially as follows: I first cut from a strip of metal a circular disk or blank 1, and by suitable tools and a series of operations draw the same out to form a cylindrical body 2, closed at one end and having at its opposite end an annular flange or rim 2. When the cylindrical body 2 has been drawn out to an adequate length I flatten it into oval or elliptical shape (Fig. 5) allowing the rim 2 to retain its circular outline. I next by proper tools and a further series of drawing operations form the closed end of said body 2 into a hollow ellipsoidal head 3 (or bean as it is commonly termed), and further reduce and draw said body down tapcrlngly from the rim to the bean to form a neck adjacent the bean, as shown in Figs. (5, 7 and 8. I thus have formed a one-piece shank and bean, the shank having a circular flange at its top and an oval or elliptical tubular body tapering to a neck adj accnt the bean, and said bean being of hollow ellipsoidal form integral with the shank. (Figs. 6, 7 and 8). The shank and bean I next subject to a further operation which flattens the rim and that portion of the shank above the neck into tubular oblong form (Fig. 9), and then, after inserting in the opposite ends of said oblong suitable formers, I further flat ten said parts and thereby bring them into fan-shape with their opposite walls in close abutment, and form at the opposite ends the tubular passages 1, l, diverging from the channel leading out from the ellipsoidal bean 3. (Figs. 10 and 11). I next cut out and remove that portion of the shank which lies in triangular form between the opposite tubular passages 4L, 1-, thereby producing the Y-shaped shank shown in Fig. 12.

In cutting out the triangular portion of the shank, as described, a scarf may be left at the juncture of the walls of the passages l, 4, in which case a further operation serves to burnish and close and conceal the joints and unite the edges of said walls. The next operation further reduces the bean into the proper ellipsoidal form to permit of its easy insertion through the button hole. The final operation bonds the shank into the proper finished state shown in Fig. 13, and the shank is then ready for the attachment to the ends of the Y of any desired button or stud head.

In the practical operation of my invention I have found that, as I do not have to anneal the stock for the successive operations, I am enabled to construct my shank and bean from plated stock and preserve and maintain the plated surface. The shank terminating, as shown and described, in a Y, is peculiarly adapted to serve the intended purpose of preventing the button from turning in the button hole, while its tubular form and the fact that it is made integral with the bean enhances very positively its strength and durability. It is obvious that the arms of the Y may be made of unequal lengths to give the desired inclination or pitch to thebutton head attached to them, and that the bean may be, if desired, of any hollow form, and that the tubular Y shank may be made of any desired cross section, without departing from the principle of my invention. 7

I claim as my invention, and desire to secure by Letters Patent:

The herein described mode of forming for buttons, studs and the like, a hollow seamless bean and a tubular Y-shaped shank integral with each other, the same consisting in drawing a circular disk of metal into shape of a fan having its lower portion tapered to form a tubular neck terminating in a hollow seamless bean integral therewith, pressing the op- Copies of this patent may be obtained for five cen posite walls of that portion of the fan located above said neck into close contact with each other in their mid portions; forming at each opposite edge of said fan portion a tubular passage communicating with and diverging from said neck; and cutting out and removing the triangular portion of said fan bounded by said tubular passages and said tubular neck to thereby form a tubular (shaped shank and a hollow seamless bean integral therewith.
