This invention relates` to buttons and set- A tings therefor, and has for its principal object to provide a button and settingcomb-inac tion adapted to be attached conveniently,

economically and securely to material by driving the setting through the material and clinching it to the button.

To this end it is an important feature of the invention that the button back is provided with openings for receiving the Work .penetrating ortions of a setting and with clinching sur aces adjacent said openings for causing said work penetrating ,portions of the setting entering the back of the button to be 4 15 deformed and clinched in interlocking relation with the back of the button. l

Aln accordance with a preferred illustrative form of the invention the button desir ably comprises a top or shell and a button back or'collet fixed to the top and forming a chamber with the top, the collet being provided with openings for receiving the prongs or other penetrating members of a setting and with deliecting surfaces for intercepting and deflecting the setting prongs or other penetrating -members and directing them in non-parallel relation through the openings into the chamber.

Other objects and advantages will heres inafter appear. In the drawings forming part of this s eciication and illustrating certain preferre embodiments of the invention: I A

In the illustrative form of the invention disclosed in Figures 1 to 4 a. setting 1 is shown driven throu h a piece of material 2 and clinched to a utton 3. `The button includes a shell or top 4 having a cover 5 of fabric or other suitable materlal Wrap ed around it and folded inward around the ange thereof. A collet 6 of suitable metallic material is 1 driven into the shell and the flange portion of the shell is pressed. inward to grip the marginal material of the cover 5 to the collet.

secured together. z The collet 6 and the shell 4 are both cup-shaped, and 'since their concavlties face one another they cooperate to y .form a hollow bodied button. The collet illustrated is designed to cooperate with the setting 1, which comprises prongs 7, and a body portion 8 having'a central Jig'opening 9 therein. The collet is designed to deflect the prongs 7 ofthe setting and clinch them to itself, and is, therefore, made of harder metal than the setting. The collet comprises a central portion 10 and is cut through alon a series of separated arcs 11 bounding suc through the openings in the collet, 'and cause them to be wrapped around and interlocked with the central portion 10 of the collet. By this means the collet` and the setting are permanently clinched to one another at a single operation to permanently secure the button 3 to the material 2. It will be seen that the'prongs extend convergently into the button, and that force tending to separate the clinched setting from the bottom to be effective to produce separation must straighten out the prongs. The inner edges of the clinching portions 12 are almost in vertical alignment with the outer edges of the central portion 10, however, so that in order for the button and setting to be separated the prongs would have to be kinked very sharply. For this reason separation of the button and setting requiresvmany times the force required for securing these members together.

The clinching portions 12 are symmetrically disposed about the center of the collet 6 and the prongs 7 are symmetrically disposed around the center of the body portion 8 of the setting 1. It is desirable that the button and the setting be accurately positioned relative to' one another for the setting operation. The button may obviously be situated in a jig or holder in predetermined position for the setting operation, but it is not desirable to grip the setting eripherally. The central jig opening 9 is esirably provided in the setting body for the receptlon of a 31g pin or plunger and serves to center the setting with reference to the button.

The form of button employed may 0bviously be varied by omitting the fabric covering, if desired. The shell, whether covered or uncovered, may be made of any suitable material, but either metal or Celluloid is preferred in the embodiment of Figures lto 4.

The embodiment disclosed in Figure 5 is generally similar to that of Figure 1, but differs in that the collet is of modied'construction. The collet 6a includes clinching portions 12 which slope toward openings that let into the collet,and the collet is used lnconJunction with a settin 1 like that of Figure 4. In this form o the invention, however, a central portion of the collet is depressed to form an interior boss 10a. As the prongs of the settingl are driven against the collet they are deected inward by the clmching portions 12'L and are directed through the openings in the collet. Upon entering the collet, however, they come into engagement with deflecting surfaces 13 on the boss 10a which bend them in the reverse direction so that they arewrapped around the inner extremities of the chnching portions 12 and are thereby caused to be bound very securely to the collet. i

In the form of the invention shown in Figures 6 to 8 the button construction is generally similar to that of Figure 1, but the collet and setting are of modified form, so that the setting prongs are deflected outward for clinching, insteadv of inward. In this form of the invention the central area of the collet 6b is bounded by slits 11'J and sectors of the central portion are displaced inward to provide openings through which the setting prongs must pass from the center toward the periphery of the button. The displaced portions of the central portion of the collet form clinching portions 12b which slope toward the openings and which serve to intercept the setting prongs and deflect them outward through the openings. The setting in this instance consists of a metallic disc 14 having parallel prongs 15 punched from the body portion thereof. These prongs are situatedrelatively near together and are adapted to strike the clinching surfaces 12b as the setting is pressed toward the collet. As a consequence, the prongs are deflected outward and are interlocked with the marginal portion of the collet, as shown best in Figure 6.

In Figures 9 and 10 disclosure is made of a collet generally similar to that of Figures 6 and 7, but adapted for use With a setting which is not initially provided with prongs. The collet 6 has sectorsof theLcentral portion thereof displaced inward to provide clinching portions 12C. Between these clinching portions 12 the collet material is desirably displaced outward a little to provide slitting projections 10. The setting in this instance is in the form of a tubular e elet 17. When the eyelet is driven against tiie projections 10c it is slit by the projections, and the legs thus formed are deected outward by the clinchin surfaces 12c and caused to pass through t e openings in the collet and tobecome interlocked with the marginal portion of the collet, as seen in Figure 9.

In Figure 11 disclosure is made of a solid bodied button of the kind usually made of ivory, composition, bone, pearl or like materials having the present invention incorporated therein. The button top 16 has a cavity 17 formed in the rear face thereof, which cavity is 'of smaller diameter at .its mouth than at its base. In other Words, the Side Wall of the cavity is undercut. A collet 6d is inserted in this cavity so as to form a hollow bodied button as before. The collet 6d may be similar in every respect to the collet of Figure 1. with the exception that the ange portion 18 of the collet is provided with V-shaped notches 19, and that the flange portion 18 isi normally flared and therefore frusto-conical rather than cylindrical. When applying the collet to the button top 1G the segments of the flange 18 are pressed together to enable the collet to enter the mouth of the cavity 17, but after the collet has been inserted part way the pressure is removed `from the flange seg ments so :that upon the full insertionof the collet the flange segments spring outward to hold the collet nterlocked to the button top, as shown in Figure 11. The collet disclosed in Figure 11 may be adapted for cooperation with any one of the settings herein disclosed, but as illustrated is adapted for vcooperation with a setting of the type shown in Figure 4.

The term setting as used herein is intended to be inter reted broadly as .applying to any type of astening member adapted 15 to have portionsv thereof driven into the collet and clinched iii interlocking relationv therewith. Such a setting may be, for example, in the form of a staple, rivet, eyelet or other driven fastening. go While we have illustrated and described 1n detail` certain preferred forms of our invention, it is tobe lunderstood that changes may be made therein and the invention embodied in other structures. We do not, there- `fore, desire to limit ourselves to the specific Y constructions illustrated, but intend to cover our invention broadly in whatever form :its principle may be utilized.
