To all whom it may concern.'

`Be itf known that LFoinissT GfPURiNfroiY, a` citizen `of the United States of America, residing at ilaterbui-y, inV the county of New Haven and State of Connecticut, lhave invented certain new and useful Improvements in Buttons, ot which the Jfollowing is a specification.

`ltlyfinvention relates to new and useful improvements in buttons and` moreparticularly' toa button that is made ot metal such as aluminum orzinc, and in its broadest aspect is of the same general type as the button showin in a previous application filed by me in the United States Patent-Qiice on April ll, 1923, and bearing` SerialNumber caisse.

One of the objects of thev present invention is to provide a button of the character described which will be neat and attractive in appearance, rugged in constructie-n and so designed that itmay be manufactured in large quantities at an exceedingly low cost.

Ihave found that it is desirable to so ar range the eye shank that it willassume a delinite position when `being fed through the automatic machine, and will assume also ay definite position when being inserted in the head or body of the button. In the present invention this is obtained by tirst securing the eye shank to a disc or shell or what might be termed a sub-base, the subbase not only providing` a more rigid construction when the button is assembled` but also holding the eye shanl in the desired position as the plunger oi the machine swedges the metal of the button about t-he baie.

In the fermer application above referred to, it was necessary for the sweco'ing tool to engage the eye and should the eye be slightly out of alignment, the anchorage might not be all that is desired. By the present arrangement, however, the tool that is used to force the aluminum or Zinc of the butt-on over the edge of the shell or sub-base, may have a` clearance hole in the middle thereof large enough to readily clear the sides ot the wire eye, thus allowing more lee way in the accommodation of the eye to the swedging tool.

With these and other objects in view, the invention consists in certain new and novel constructio-ns and combination of parts as the head.

Fig. 2 is a similar view with the parts assembled.

VFig. 3 is also a similar view, and showing the metal ol" the head swedged about the suhbase.

Figa is a. perspective of the button,

Figp is a bottom plan view.

Fig. 6 is a sectional view oi" a slightly modified form, and

Figarin `is a similar view oi? a still l'urthcr inodication.

Referring now to the preferred form, 'the head l of the button is formed son'lewhat similarly to that shown in `myfornier construction, wherein a rod or wire (not shown) is cut. tofrom a slug, or rod-lilre `blank and then subjectedv` to suitable dies in a heading machine, andpreLsed to the desired shape, as shown inliig. l. lt will be seen that this head is preferably curvi-orm as at 2, a central hub 3 being provided which is recessed or hollowcd out as at i, the rim cvte ding outwardly as at 5, and merg with the hub as at (S. By pressing the hu ton head into this shape, the upper portion of the hub is in the forni ot' a rim which is to be swedgcd, as will he shortly described.

lt will he understood that the top ot 'the button might he a plane suriace rather than that Shown, but the slightly curved outer Yface preents a. near and pleasing lorm ol' button.

Referring now to what l terni the sub-base T, it will be seen that it consists of a met-ai shell or disc substantially heinisphericall \v in shape, while forced centrally through the top thereof is the eve shank 8 having its ends bent or crimped against the top of the shell to thus form a tight and rigid construction between these two elements. The diameter ot this shell is slightly less than the recessed portion i formed in the head of the button so that the sub-base, during its assembly in the machine. may slide or drop within this pocket, the shell meanwhile supportino the eye shank intits proper position. The depth of the shell is slightly. greater than the depth of the recess i as will be apparent 'from the several figures. After the shell has dropped into its position, the metal rim is properly swedged by the plunger (not shown) to tightly anchor the shell in position, as may be ciearly seen in Fig. 3.

- ln the modified form, as in Figz, a soit metal head 9 lis shown in which there is ormed a slight central aperture l() and placed therein is the shell or sah-base ll, in which there has been formerly securedV the eye shank l2. The metal around the aperture l0 will then be swedged;inwardly to tightly grasp or anchor the shell ll and its eye 12, in position.

ln a like manner, the modiiied' form shown in Fig. 7 illustrates a button heed 13 of soft metal and instead of havinga central aperture or cnt-ont portion in which.y the subb'ase fits, there is shown an annular groove, recess or depression lei in which will tit the Vedge of the shell or sah-lease, thelatter ot course provided with the eye shank 16. n this orm'also, the metal about the edge ot' the recess or groove will be swedged in- .wardly to tightly anchor a shell or enh-base l5 within the button head.

From the foregoing it will he seen that I have provided a button wherein the head is preferablymade of sott metal which permits advertising or other insignia to he pressed on the face thereof, and at the same time provides a button that is neatin appearance and easily assembled. Furthermore, the preliminary attaching of the eye shank to the sub-base or shell not only makes it possible to make aV rigid form of button, lont allows the button to be made at a maximum speed inasmuch as the plunger may work on the shell with the eye shank in its proper position rather than have the plunger descend upon a shank that is not in its proper position 'Y l am aware that it is old in the art to provide asoft metal button and to swedge the same about the lower ends of the eye shank, and do not claim this invention broadly as shown, but what l do claim and desire to secure by Letters `atent is fr button comprising a metal head, said head prov'ided with a central hub of greater thickness than-the ymean thickness oi' the head, said huh havingl a recess portion thus sroviding an ui standingrini, a sub-base formed oi a metal disc, cup-shaped in cross sectionv and itsexposed surface being curved throughout,V said sub-base being fitted with- .in the recess portion and the peripheral edge ci its downwardly extending,` walls contacting with the bottoni of the said recess portion, an ey-elet secured in saidV sub-oase and the metal rire swedged to anchor the said base within said button and the rim when swcdged extending in a plane ahove the surface or the. button and substantially `in the .ame plane as the curved upper surface ot' the sub-hase, the swedged rim and the upper surface of the sub-base providing a space between the button head and the material to which it is to be fastened.

In testimony whereof l ailix my'signature. l v
