BUTTON.

Application-filed February 9, 1927f8er1a1 No. 168,910.

This invention relates to buttons, more particularly those formed of metal such as aluminum the present invention having for its object to provide a light weight but: substantial button of good appearance which may be produced expeditiously and cheaply, and, more particularly, from relatively light weight sheet stock. 1 T o accomplish this object a blank of'sheet metal is formed up into a button having a hollow rim presenting rounded edges smooth and concentric with adished portion within the rim providing a space for thest-itches and which holds thehollowrim spaced from the face of the goods to which the button .is

applied.

For a more complete understanding of this invention, reference may be had to the accompanying drawings in which Figure 1 is atop plan of one form of the button. f

Figure 2 is a cross section on line 2-2 of Figure 1. I 7

Figures 3 and 4 are views similar to Figure 2, but showing modifications.

Figure 5 is a cross-section on Figure 4'.

Referring first to Figures 1 and 2, the button is formed of relatively thin sheet metal dished at its'central portion to produce a central web at 10, herein shown as circular in outline, terminating in an upstanding marginal annular wall 11, the upper edge of which is folded outwardly and downwardly asat12 and then inwardly as at 13 into substantial contact with the outer face of the portion 11 above its lower edge, thus forming a hollow head or rim for the button. The central web portion 10 is perforated as at 1% with stitch-receiving holes, the edges of these holes preferably being rounded as at '15 to prevent cutting of the stitches passing from one hole to the other.

As shown in Figure 2 the central web portion-is downwardly dished but if desired it may be formed fiat as shownjin Figure 3. In Figure 3 also the marginal head is shown as formed of different cross section than that shown in Figure 2, its upper face presenting a gradual curve. the maximum distance. from the base of the button being substantially halfway between the maximum and minimum diametersof' the head, while in the construction shown in Figure 2 the maximum'thickness-of the rim portion of line 5-43 of the button is closely adjacent to its minimum diameter portion and its upper face is sub-' stantially flat.

In place of forming the stitch-receiving holes as shown in Figures 211ml 3', they may be formed in the manner disclosed in Figures 4 and 5. Intheso figures it will be seen that substantially semicircular cuts 21 are made through the central web portion thus partly severing semicircular tabs 22 which. are struck upwardly from the cent-ral web portion andthen bent downwardly against the outer face thereof, thus forming roundededges 23 'diametricalwith respect to the portions partly cut, these edges being so disposed as to have engagement with stitches passing from one holeto the other. Whether the holes are formed by completely severing or by partially severing and then bending,

thecentral dished port-ion of the button provides a spaceto receive the stitches so that they do not project beyond the rim portion of the button. It is of course evident that any desired number of stitch-receiving holes may be provided.

The run portion being formed by folding the sheet metal stock so that its edges substantiallyabut the upstanding wall portions of the dished central portion, producesa smooth rounded rim portion for the button which because it is hollow is considerably lighter than were it made Solid. The edge portions of the stock being in substantial contact with the annular upstanding wall portion, the exposure of rough or Sharp edges .is avoided without special treatment of the cut edges of the blank and the back face of the button about theused portion presents a Substantially flat face to the fabric about the button hole. The button thus closely simulates a bone or horn button of good quality.

Having thus disclosed certain embodiments of this invention it should be evident to those skilled in the art that various changes might be made therein without departing from its Spirit or scope as defined by the appended claims.

I "claim:

1. A Sheet metal button comprising a central circular portion pierced for the reception of securing stitches, and an annular wall portion about the margin of said central ortion, the edges of said annular portion eing rolled back into Substantial conwith the outer face tart with the outer fuee of said wall portionto form an annular hollow bead;v I 2. A sheetmetal button COIIlPl'lSlIlg a central circular portion pierced for the reception of securing stitches and an annular Wall portion about the margin of-smd central portion, the edges of said annular portion being-folded back into substantial contact of said wall portion above its juncture with said central portion to form an annular hollow bee-d spaced above the work to which said button may be L attached."

3. A button comprising a thin web having spaced portions partly severed therefrom and bent toward each other against the face partly severed therefrom and bent toward each other along their diametrical edges nnd againstsaid web to form spaced stitchreceiving openings presenting the rounded and thickened edges at the bend for engagementwith stitches passing from one to another.v In testimony signature.
