BUTTQN FASTENER Filed Sept; 26. 1930 -WM. Lawmw 6551mm Patented June 2, 1931 UNITED STATES LAWRENCE B. ERWIN, MARBLEHEAID, MASSACHUSETTS BUTTON FASTENER Application filed September 26, 1930. Serial No. 484,613.

My invention relates to button fasteners and particularly to those which may be used for securing perforated commercial buttons to fabrics or the like.

5 One object of my invention is to provide a fastener that permits use with varied thicknesses of material or buttons.

A second object is to provide a button fastener of the kind noted which shall be of sim- "iU ple character, and economical in manufacture.

My invention consists in the combination of a yielding pointed element adapted to pass through the eyes of a commercial button and to engage with a perforated holding element,

tion which may be employed with a button having a single perforation.

Fig. 3 is a perspective view of the holding element shown in Fig. 1. o

Fig. 4 shows modified forms of both pointed element and holder.

Fig. 5 is a perspective view of a pointed element such asmay be used with the device as shown in Fig. 2.

Referring to the drawings g The perforated button A is provided with a socket 10, and the pointed element 11 passing through the perforations, may be formed of wire, of a shape adapted to yield as it is pressed through the fabric B and into the holder 12.

In Fig. 1, I have shown this pointed element formed with a loop 13, which permits yielding as the legs 14 are pressed into the fabric. In Fig. 4 the form of the pointed element at 13 is equivalent.

The legs of the pointed element are enlarged near the end to form shoulders 15, and each leg may be slotted as at 16for reasons to be explained.

The holder 12 is formed with perforation l7 agreeing axially with the legs of the pointed element, and may be formed from a strip of relatively thin sheet metal, the perforationsl7 being countersunk slightly as at 18, in the direction of thrust and of a size that will require appreciable pressure to force the pointed element therethroughto engage the sh0ulders15.

- The perforations may be provided with the slots 19 radiating from the perforations, andforming tongues 20 which are slightly deflected to enlarge the perforations as the pointed element is pressed through. The slotted ends of the pointed element cooperate in this and as the two parts are pressed together, the shoulders 15 pass through the perforations 17, the countersunk formpermitting passage of the enlarged portions of the pointed element to engage the shoulder with the underside to resist withdrawal.

In Fig. 4, I have shown a modified form of holder in which the perforations 17 are provided with a single tongue 20, which extends inwardly, and is adapted to be deflected, as the pointed'element is inserted through the perforation,;the enlarged portion passing through and the shoulder 15 engaging therewith to resistwithdrawal. V

Fig. 5, is particularly adapted foruse with the construction shown in Fig. 2, the pointed element 21 being bent to permit yielding as at 23 and to hold against the inside of the material towhich the button is to be attached, the point 22 being pressed into the holder 12 which in this case is seated in the socket 10 of the button, and is of equivalent construction to the holder shown in Fig. 3, the form bein varied to fit'into the socket 10, with'a per oration similar to perforations 17 1 With the forms shown boththe pointed element and the holder element are formed to yield as the pointed element is inserted into the perforations. It thus follows" that the enlarged portion of the pointed element may be slightly larger than the perforation into.

which it is pressed, and either or both elements will yield sufficie-ntly to permit passage of the enlarged portions of the pointed elemen't, under axial pressure to engage the shoulders of the pointed element with the material surrounding the respective perforations to resist separation of the elements.

Having thus described my invention, I claim:

1. A button fastener comprising in combination an element I having pointed extensions adapted to pass through the perforations of a button and to yield axially, and

provided near the ends of such extensions with enlarged portions forming shoulders; a holding element having openings in axial agreement with the pointed extensions; means adapted toyield under axial pressure, to permit passage of the shoulders through the openings to engage the holder and to resist separation of the elements.

' 2. In a button fastener having an element with pointed extensions and enlarged portions thereon forming shoulders, the combination therewith of a holding element having openings in axial agreement with the pointed extensions, and means adapted to yield and to engage the shoulders on the extension when axial pressure is applied, and to resist separation of the elements.

3. In abutton fastener having an element with pointed extensions and enlarged por- LAWRENCE B. ERWIN.

tions thereon forming shoulders, the combination therewith, of a holding element hav ing openings in axial agreement with the pointed extensions, the contiguous material being adapted to yield under axial pressure to permit passage there through of the enlarged portions .ofthe extensions to engage the shoulders with the holder and to resist separation of the elements.

4. In a button fastener having an element with pointed extensions and enlarged portions, thereon forming shoulders, the combination therewith of a holding element having perforations in axial agreementwith the pointed extensions, the contiguous material being formed with tongues adapted t'obe deflected to permit the passage through the perforations and under axial pressure, of the enlarged portions of the pointed extensions to engage the shoulders with the holder and to resist separation of the elements.

5. In a button fastener having a perforated holding element,the combination therewith of an element having pointed extensionsrand enlarged portions thereon forming shoulders and adapted to extend through the perfora tions of a button andlthe material to which it is to be attached, and to yield axially under axial pressure, toprovide for varied thickness of button and material, and to vpass through the perforations of the holder and engage the shoulders therewith, to resist separation of the elements.
