Referring to the embodiment of my invention illustrated bythe drawings, I have shown fa button which .is particularly adapted to be secured to garments or other v material bymeans of a? metallic fastening device turned'and concealedby anv anvilportion inthe button.` p i Hcretofore buttons ofthis. class have been formed from sheet metal. and also yfrom v solid bar stock.y The Vsheet metal buttons y have been ormed-with abody part and a separate anvil part securedrin various yways to the body part. Therefore, at least two separate pieces were required to provide the bodyand anvil portion. Buttonsapresent- Y ing one-piece body and` anvil portions have heavy vas compared with a sheet metal but- Y ton.

My invention, as illustrated by the drawings, isdirected toa sheet metal button which has the'anvil or turning and clenching means formed integral withy thev body part of the button and also relatesto the method of making such a button.

f The body part may constitute the-entire button ory may be the body or back portion of a plural-part button when combined with a whole or partiall cover part, vas shown in Figs. 14 and .15 which are described more in detail in my co-pending applications Serial No. l297,808 and SerialNo. 297,809

The button illustrated vby Figs. 1 and 2 has a body portion which includes the headk 1 (being the part which passes` through ka buttonhole), a cup-shaped shank 2 Vformed Yintegral with the head, and ananvil 'por-v In this instance I have shown (Figs. 2 Aand Y 4) a tack 6which mayl be of anysuitable structure, piercing. a suitable vcarrying medium 7 and having its pointed end portion with thel inturned double wall portion 4 to hold the button' in place upon the carrying medium '7. f 1

tack from piercing lthe anvil portion. When the attachment is complete the shank of the tack is concealed and the button presents a neat and finished appearance and therel is no portion ofthe tack exposed which may. rust Referring now to the method 'of making the body portion with the integral anvil,- as shown inV stepbystep Vform inrFigs. through 13, I havey illustrated various which perform the various operations. The fiat blank shown in Fig.,5 is first passed be tween the dies 11 and 12 (Fig. 6) which cup the blank, as shown in cross-section.' The cup-.shaped part then passes between dies land 14, vshown in Fig. 7 where the head and cupshaped shank 2 are formed InV this form itis passed between the dies 15 and 16 (Fig. 8) and the vbottom of the cupshaped shank 2 is pressed toward the open end of the cup to begin the Vformation of the anvilor clenching and turning means. The blank next passes between thedies 17 and 18 `(Fig. 9) and the dies 19 and 2O (Fig. 10) to complete the process ofpressing the lbottom of the cup-shaped portion toward the mouth of the shank and form the double thickness wall portion 4. In Fig. 11, the V,dies 21 and 22'turn the wall portion 4 in- J wardly toward'the center of the shankv and against the projection 23 on the die 22 to form the restricted opening 4a surrounded I by a'substantially' perpendicular wall.V The button is complete at Vthis stage, but I prefer to'provide the head 1 with a rounded flange '24, so I pass it from between the dies 21 and 22 through the dies 25 and 2oV (Fig. 12)` and between the dies 27 and 28' (Fig. 13) where the flange is completed vand the button is then turned out Complete from a single piece of sheet metal.

VMy improved button and the method of forming thevsame aife'simple and, while I have shown a complete oneepieoe sheet metal button, Vmy invention is more-particularly directed to the formati-on ofthe anvil means as an integral part'of the body of a button which is pressedfrom sheetA metal. he shape of the head 1 of the body may be varied. preferred forms being shown in l Figs. 2 and 3. rlhe head of the body may be'covered by another piece ofmetal or fabric or the like if desired, preferred forms being shown by Figs. 14 and 15 and in my applications hereinbefore referred to as filed herewith'. f

While I have illustrated and described my invention somewhat in detail, I do not wish to be limitedthereby as the rscope .of my invention is best definedin the following claims.

Claims: 1. YA metal button having a body formed of sheet' metal, said body having as integrai rparts thereof, av head, a'shank having .a redies'.

` attaching element.

stricted opening at the bottom end thereof, and a generally arch-shaped anvil portion housed within and integral with said shank, Y
