UNITED STATES FORREST G. PURINTON, OF

BUTTON COMPANY, or WATERBURY,

NECTIOUT.

WATERBURY, CONNECTICUT, ASSIGNOR TO THE PATENT CONNECTICUT, A CORPORATION OF CON- BUTTON.

Application filed April 11, 1923.

To all whom it may concern:

Be it known that I, FoRRrs'r G. PUniNToN, citizen of the United States, and a resident of \Vaterbury, in the county of New Haven and State of Connecticut, have made and invented certain new and useful Improvements in Buttons, of which the following is a specification.

My invention relates to ring or eye-shank buttons and has for its object to provide a button of this character which is so designed and arranged that the various operations necessary for its manufacture may be eficiently carried out upon an automatic heading machine and thus providing for the economic production of large quantities of the buttons.

A further object is to provide a button of the character described which will be of neat and attractive appearance, strong and rugged in construction, and so designed and arranged that it may be produced in large quantities at an exceedingly low cost, and with the foregoing and other objects in view, my invention consists in the improved button illustrated in the accompanying drawing and hereinafter described and claimed, and in such variations and modifications thereof as will be obvious to those skilled in the art to which my inventionrelates, it being understood that changes may he made within the scope of what is claimed without departing from the spirit thereof.

The preferred embodiment of my inven tion is disclosed in the accompanying drawing, wherein:

Figure 1 is a view in side elevation of the slug or first stage blank;

Figure 2 is a view in section of the second stage blank as it comes from the automatic heading machine;

Figure 3 is a bottom plan view showing the third stage blank;

Figure st is a view in section showing the fourth stage blank and with the eye inserted within the shank or hub; v

Figure 5 is a view in side elevation of the completed button, the metal of the hub or shank being overturned against the ends of the eye and anchoring the same in place;

F igure 6 is a bottom plan view of the same;

Figure 7 is a bottom plan view of a somewhat modified form of third stage blank, the stabbing in the hub or shank partaking Serial No. 631,254.

of the nature of a circular recess instead of a straight slot;

Figure 8 is a bottom plan view of the eye for use in connection with the blank as shown in Figure 7 Figure 9 is a view in side section of the modified third stage blank having the eye of Figure 8 therein;

Figure 10 is a View in side section showing the metal of the hub turned inwardly against the end of the eye of Figure 8;

Figure 11 is a view in section of a somewhat modified form of second stage blank, the same being without anysharply defined hub;

Figure 12 is a View in section showing the abovementioned modified blank provided with a recess and an eye therein; and

Figure 13 is a view in section showing the completion of this modified form of button.

Referring specifically to the several views, wherein similar reference numerals designate corresponding parts throughout, a wire or rod (not shown) is cut to form a slug on rod-like blank 10 as shown in Figure 1. This blank is then subjected to the action, of'suitable dies in a heading machine and is formed to the shape as shown in Figure 2, and which I term the second stage blank 11;

This second stage blank 11 preferablyineludes: a disc or flange 12 having protrud= ing from one side a centrally located hub or thickened port-ion 13. -This' hub is of approximately the same diameter as the diameter of the rod-like first stage blank 10. The second stage blank is then subjected to the action of a second set of dies (not shown) and a. slot 14 is stabbed or formed into the shank or hub 13 and into which slot or recess is inserted the ofiset ends 15 of the button eye- 16. Vith the eye thus located in place as illustrated. in Figure 4;, still another set of dies (not shown) causes the mctal surrounding the slot 1st to close down upon the ends 15 of the eye, as at 17, and permanently anchors and secures the eye in place. These dies also produce a nicely rounded hub 13 and thus provide a button of pleasing appearance, as well as rugged construction.

Vhile I have described the above operations as taking place in separate machines and operated upon by separate dies, yet it will be readily apparent that the dies may all be incorporated in a single machine and the various stage blanks produced and operated upon in proper and continuous sequence. The original flange 12 of the second stage blank is durin the subsequent operations formed to the desired shape and may be suitably embossed or decorated so as to present a neat and pleasing appearance; and, further, may be of any desired outline or configuration, in accordance with well-known heading practice. The various operations may be most rapidly carried out and buttons: produced in large quantities at an exceedingly low cost and without scrap or wastage.

A somewhat modified form of button is disclosed in Figures 7 to 10, wherein the hub 18 of the third stage blank illustrated in Figure 7 is provided with a circular recess 19 and accordingly is adapted to accommodate an eye 20 as illustrated in Figure 8, the eye in this instance being provided with two oppositely extending arms 21 bent so as to form segments of a. single circle. The base of the eye is then inserted into the circular recess 19 as illustrated in Figure 9 and the forming dies then swedge the metal of the hub so as to cause it to flow inwardly and over the base of the eye, as illustrated in Figure 10, and thus permanently anchor the eye in place.

In practice it will be readily appreciated that various modifications may be carried out and as an example attention is called to Figure 11 wherein the second stage blank is not provided with any sharply defined hub but is merely provided with the thickened central portion 22. This thickened central portion is then subjected to a stabbing operation to provide the recess or slot 23 and into which the ends 24 of the eye 25 are inserted. A swedging operation then causes the metal 26 to flow around the ends of the eye and thus permanently anchor the same in place.

I have also found that the punch which operated upon the second stage blank of Figure 2 to produce the third stage blank, may be included in the dies whereby the second stage blank was formed, so that the first stage blank of Figure 1 will, in one operation, be transformed into the blank as illustrated in Figure 3 or Figure 7, thus doing away with one operation; such changes and modifications, however, coming clearly within the scope of my invention.

After the button has been thus completed, it will be readily appreciated that the same may be lacquered, enameled, or in fact any of the usual types of caps could be secured upon the head of the button. This method of finishing a button is of standard practice, however, and is therefore not herein illustrated.

Having thus described and explained my invention, I claim and desire to secure by Letters Patent:

1. A button of the class described comprising a head, an integral thickened central portion or hub having an opening extending in from the lower surface thereof, and an eye with the lower ends thereof bent into a plane at right angles to the plane of the eye to form a support for the eye and with the said bent ends extending within the said opening or recess and the side walls of the recess overturned against the ends of the eye and rigidly anchoring the same in place.

2. A button of the character described comprising a head, an integral thickened central hub having a recess therein, an eye with the ends thereof bent in the form of the letter S to form a support and lying in a plane extending at right angles to the plane of the eye, said bent endspositioned within said recess and with the side walls of the recess overturned thereagainst and rigidly anchoring the same in place.

Signed at Waterbury, in the county of New Haven and State of Connecticut, this 6th day of April, A. D. 1928.

FORREST G. PURINTON.
