CQNNEOTICUT, A CORPORATION OF SEPARABLE FASTENEE.

Application filed August 8, 1919.

To all whom it may concern:

Be it known that I, CHARLES A. MILLER, a citizen of the United States, residing at Waterbury, county of New Haven, State of Connecticut, have invented a certain new and useful Improvement in separable Fasteners, of which the following is a full, clear, and exact description.

My invention relates to socket members for separable fasteners having a reinforced cap or cover portion, and has for its object to produce the outer portion of such a min forced socket member 6., the socket member exclusive of the attaching rivet), having only two parts, namely, the base portion and the cap or cover therefor. This reduction in the parts of such a reinforced socket member produces a better product in a simpler manner, saving materially machine operation necessary to produce the separate parts and in the manual labor necessary, and also producing a more perfect product. The elimination of any separate part in such a socket member results in a material saving, since the. parts are small and difficult to handle and the saving of even one operation in the process of assembling, to say nothing of the saving of the separate manufacture of a separate part, is of material importance.

It also has for its object to provide a socket member having a combined collet and anvil and in which the edge of the eyelet is crimped inward somewhat before it reaches the securing recess while being inserted. It further has for its object to provide such an outside member in which space is pro vided adjacent to the base of the rivet portion of the eyelet so that the eyelet can bulge outwardly at that point and tends to do so while being inserte The following is a description of an embodiment of my' invention, reference being had to the accompanying drawing, in which Figure 1 shows a vertical section through a socket member embodying my invention as secured to a piece of fabric;

Fig. 2 is a plan view of the outer portion of the socket member with the cap or cover removed;

Fig. 3 is a side elevation of the same;

Fig. 4 is a bottom view of the same;

Fig. 5 is a plan view of the securing rivet before insertion;

Specification of Letters Patent.

Patented Apr. 20, 1920.

Serial No. 316,026.

Fig. 7 is a view partly in section and partly in side elevation of a cap or cover of the socket member;

Fig. 8 is a sectional view showing the base member with the cap or cover applied thereto before it is affixed to the goods; and t Fig. 9 is a sectional view of the rivet extending through the fabric and about to be inserted in the socket member to hold the same in place.

Referring more particularly to the drawings, 1 is the fabric to which the socket member is applied. 2 is the base portion of the socket member comprising a collet 3 surrounding the perforation l which is surrounded by an anvil portion 5, the edge of the perforation being turned downwardly and outwardly as at 6, the lower surface of the metal surface between the anvil and the collet being sharply inclined as at 7. Extending from the outer edge of the collet are extensions 8 which project over the upper surface of the anvil 5, being preferably closely adjacent thereto so as to be supported thereby. All the portions 3, 5, 6, 7 and 8 are integral, being formed from a single sheet metal stamping on a single eyelet machine by punches and dies and presenting no difliculty to those skilled in the art when the form to be attained is known. 9 is a cover of metal, celluloid or plastic material, which is secured in the ordinary manner to the base member as shown. This cover is reinforced by the projections 8 so that it does not yield under pressure. 10 is the ordinary rivet the upper edge of which, when inserted, engages the inclined surface 7 and is forced inwardly until it strikes the lower surface of the anvil 5 and is crimped by the anvil into the recess formed by the downwardly and outwardly turned flange 6, the lower portion of the rivet being expanded somewhat at 11 so as to form a chamber for the stud member of the fastener.

In manufacturing the socket member shown in Fig. 1, a blank is stamped out having a perforated center and a plurality of extensions. These extensions may vary in number, but I prefer to use four extensions as shown in Fig. 2, the blanks for a member having four such extensions being substantially a square blank. This blank is then acted upon so as to form the collet, anvil and downwardly and outwardly turned edge 6 and then cupped so as to have four rounded corners 12 adjacent to the metal forming the central portions of the sides of the square blank, the corners of the blank being turned upwardly so as to present substantially rectilineal intermediate surfaces, as shown at 13, alternating with the rounded portions 12. The four projections are then bent over, as shown in Figs. 2 and 3, being at this time considerably removed from the upper surface of the anvil portion, as shown in Fig. 8. The cap or cover 9 is then applied as shown in Fig. 8. Where this cap or cover is of nonplastic material, it is preferably partially preformed as shown at.9 in Fig. 7.

In securing the socket member to the fabric 1 the eyelet 10 is passed through a perforation in the fabric. .The outer portion, as shown in Fig. 8, is then placed thereon so that the upper edge of the eyelet engages the inclined surface 7. Pressure is; then applied resulting in the crimping and forming of the eyelet, as shown in Fig. 1, the anvil and projections 8 being forced toward one another until they are preferably in substantial engagement with one another, thus bringing the lower edge of the cover 9 adjacent to the fabric 1, as shown in Fig. 1. In this way the eyelet is crimped so as to secure the outer portion in place.

A reinforced socket member is thus obtained whose outside member, where a nonmetallic cap or cover is used, consists of one metallic part with the advantages above specified. WVith the fasteners so constructed the metallic parts of the outer member being integral, there are no loose parts which can rattle as in fasteners now on the market.

The sharply inclined surface 7 is engaged by the upper edge of the eyelet and the said edge is bent inwardly thereby before it enters the recess, resulting in a preliminary crimping of the eyelet. This inclined surface also provides space around thebase of the rivet portion of the eyelet so that it, can bulge outwardly at that point and tends to do so, instead of tending to bulge inwardly so as to interfere with the insertion of the stud of the stud member.

This outer member can be secured to goods of difierent thickness by eyelets of the same length.

As will be evident to those skilled in the art, my invention permits of various modifications without departing from the spirit thereof or the scope of the appended claims.

What I claim is:

1. A socket member comprising a collet, ananvil and cover reinforcing portions, all integral with one another, said anvil surrounding a perforation having a downwardly and outwardly turned edge forming a recess adapted to receive the edge of a securing eyelet.

2. A socket member comprising a collet, and integral therewith both ananvil and reinforcing extensions projecting from the edge of the collet and extending over the upper side thereof, said anvil surrounding a perforation whose edge is downwardly and outwardly turned so as to providea recess for receiving the edge of a securing eyelet.

8. A socket member comprising a collet, and integral therewith an anvil, said anvil surrounding a perforation whose edge is downwardly and outwardly turned so as to provide a recess for receiving the edge of a securing eyelet the lower surface of the metal connecting the anvil and collet below said recess being sharply inwardly and upwardly inclined.

4. A socket member comprising a collet, and integral therewith an anvil, said anvil surrounding a perforation whose edge is downwardly and outwardly turned so as to provide a recess for receiving the edge of a securing eyelet the lower surface of the metal connecting the anvil and collet below said recess being sharply inwardly and upwardly inclined, the inclination extending to the collet and providing space for expansion of the rivet portion of the eyelet adjacent to said collet. 7

5. A socket member comprising a collet, and integral therewith both an anvil and reinforcing extensions projecting from the edge of the collet and extending over the upper side thereof, said anvil surrounding a perforation whose edge is downwardly, and outwardly turned so as to provide a recess for receiving the edge of a securing eyelet, the lower surface of the metal connecting the anvil and collet below said recess being sharply inwardly and upwardly inclined.

6. A socket member comprising a collet, and integral therewith both an anvil and reinforcing extensions projecting from the edge of the collet and extending over the upper side thereof, said anvil surrounding a perforation whose edge is downwardly and outwardly turned so as to provide a recess for receiving the edge of a securing eyelet, and a cover extending over and supported by said extension.

7. A socket member comprising a collet, and integral therewith bothan anvil and reinforcing extensions projecting from the edge of the collet and extending over the upper side thereof, said anvil surrounding a perforation whose edge is downwardly and outwardly turned so as to provide a recess for receiving the edge of a securing eyelet, the periphery of said structure having substantially rectilineal portions adjacent to the bases of said projections and intermediate curved portions, and a cover supported by said extensions. 7
