BUTTON.

Application filed October 26, 1922. Serial No. 9,9 64' j To all mama may concern:

Be it known that I, FREDERICK N. Ross, a citizen of the United'States, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Buttons, of which the following is aspecification.

'T'his invention relates, to buttons, especially buttons intended for workingmens clothes such as over-alls, etc. It is the object of the present invention to provide a button of this character in which the loop or eye is securely anchored to the back of the button so that it cannot either rock or slide in and out.

- It is customary at the present time to use a card-board disc on the inside of the button to prevent the eye from moving in and out. No provision is made to prevent the eye from rocking slightly. This rocking is very objectionable, especially when this button is used in connection with an automatic machine for fastening the buttons to the fabric by forming a key ring through the eye. Such a machine is described and claimed in the prior Miner Patent No. 1,140,474. These buttons are fed automatically to this machine and if the loops or eyes are loose, they often cause considerable trouble in the operation of the machine.

In the drawings:

Fig. 1 is a section showing the blank before it is formed into the back shell of the button.

Fig. 2 shows the blank formed into the back shell.

Fig. 3 shows the back shell provided with the eye. I

Fig. 4: shows my improved method of anchoring the eye 'to'the back shell.

Fig. 5 is a section through the back shell after the legs of the eye have been welded and riveted to the inside of the shell.

Fig. 7 is a perspective view showing in detail how the Welding operation both upsets the legs and welds them in place.

in any approved way by automatic machinery or otherwise and comprise a shallow cup shaped member a. Into this, through the center hole 6 is formed the wire eye 0. It has legs d turned over-parallel and abuttingagainstthe'insitle' of the back shell. This is done by machinery that need notbehere described and results in the eye typ'eofbutton'nowinjgeneraluse. I l and out of the shell, it is customaryto -include a disc in betweenthe outer andinner shell.'

In order to: prevent the eyejfrom moving'in In my construction the-use of-"thisdisc* is" madeunnecessary.

After the eye has been passed through the back shell and the legs pressed downto abut against the back shell, the same can be placedin 'a suitable die and the spot welding electrode 6 pressed down against the legs of the eye as is clearly shown in Fig. 4. This has a double effect; it not only homogeneously unites the metal of the leg to the back shell, but it also up-sets the metal portion bythe pressing and flowing operation soas to really constitute a riveting action as well as a welding action. The welding action causes the metal of the legs and the back tounite so that the eye cannot move in and out of the shell. operation together and each alone, anchors the eye to the inner side of the back shell so that the eye cannot rock to any perceptible degree. Hence, the button is eminently well fitted to be fed into the automatic button fastening machine describedand claimed in the Miner patent supra. The spreading and The welding and l p-setting riveting action is well illustrated by inspect- I ing Figs. 7 and 8 of the drawings.

What I claimis:

1. The method of constructing a button of I the type specified, comprising the forming of a shallow cupped metal back and punching the centre, the forming of a wire eye with the ends passed through the centre opening and turned" over against the inside of the back of the metal shell and the spreading and flattening of the ends by the useof pressure in the presence of relatively great heat.

2. The method of forming buttons of the.

type specified, comprising the forming of a shallow cup shaped shell to form the back of the button andperforating the centre thereof, the forming of a wire eye and passing the ends through said opening and turning over the ended the wire to form legs abuttlng against the inside of said shell, and

homogeneously uniting the metal of said legs 1 with the metal of said shell.

buttons of the 3. The method of making stamping ofa class specified, comprising t shallow cup shaped back shell with a punched central 'opening, the forming of a wire eye and passing the ends through said open-;

ing and the turning over of Said ends to form legs abutting against the inner side of said shell and the welding of said legs to the shell.

4:. The method of making buttons of the class specified comprisingthe forming-of a 10 shallow back shell and perforating the centerthereof, the forming of a'wire eye and passing the ends through the centre and turn ing them over to form legs abutting on the inside ofthe fmetal, shell and the flattening out and spreadingof saidile gs to prevent the wire eye from rocking With respect to the shell. w 5. A button of the type specified, e0mprisdown against the metal of the back :shell. to .form legs, a portion of said .legs being ing a shallow metal shell having aicentre v opening; a wire eyehaying the ,GIid'SIOfgtll eye passed through said opening and turned down against the shellto form legs, the said legs being flattened and the said flattened I flattened to prevent rocking and the flat-- tened portions of said,legfhomogeneonsly united to the metal of the back shell.
