UNITED STATES PATENToFFlcE.

FRANKLIN R. WHITE, OF WATERBUBJY, CONNECTICUT, ASSIGNOR T0 THE PATENT BUTTON COMPANY, OF WATERBURY,

To @ZZ whom it may concern.'

Be it known that I, FRANKLIN R. WHITE, a citizen of the United States of America, residing at llaterbury, in the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Fasteners, of which the following is a specification.

My invention relates to new and useful improvementsin fastening means and more particularly to a rivet and burr designed to be fed to an automatic heading machine to permanently secure the edges or seams of overalls or other garments of a similar nature.

One of the objects of the present invention is to provide a. rivet and burr which are eX- tremely economical in construction, and wherein the same may be quickly headed, and wherein the burr may be properly held or centered during the heading operation.

Still another object of the invention is to provide a rivet and burr wherein the burr is adapted to be fed downwardly a certain distance towards the rivet until the burr engages the cloth, after which it forces the cloth against the point of the rivet to thereby pierce the cloth, which operation is then followed by the heading.

In the manufacture of overalls, it is necessary to provide some fastening means for the seams or edges which is extremely strong, due to the rough usage and heavy wear incident to this forni of garment, and the presont invention has to do with a fastening means comprising but two parts and wherein after the saine are once attached and the parts deformed, it will be impossible for the saine to ever loosen or become disengaged as the burr and rivet are then practically a unitary structure.

lilith these and other objects in view, the invention consists in certain new and novel arrangements and combinations of parts as will be hereinafter more fully described and pointed out in the claims.

Referring now to the drawings showing a preferred and slightly modified form,

Fig. 1 is a perspective of a rivet, a strip of cloth and the burr, the several parts being shown before the burr and rivet are attached.

Fig. 2 is a sectional view, the burr being shown as forcing the cloth against the rivet or tack point.

CONNECTICUT, A CORPORATION OF CON- FASTENER.

Application filed October 27, 1925. Serial No. 65,164.

Fig. 3 is a top plan view of the burr showing a slightly modified form.

Fig. 4 is a view showing the modified form of burr and in its locked relation with the tration, as in reality the rivet and burr are rather minute, the burr being about a quarter of an inch in height and the rivet slightly longer.

Referring now particularly to Figs. l, 2 and 5, I have shown a burr comprising a hollow hub l, and the small rim or flange 2 formed at-the lower end thereof, the entire burr being preferably formed of copper, and of course, of one piece.

The 'rivet or tack comprises the prong 3 with the head or base 4, this rivet being similar to the tacks or rivets used in many forms of patent buttons. It will be understood that in the application of these fasteners, the rivets will beplaced in one hopper and the burrs in another of a heading or attaching machine, and the heading then performed in a quick and rapid manner.

By having the burr the depth shown, it

permits the rivet to pierce the cloth before it is headed, whereas, if the burr was of the finished shape before it was attached, the body of rivetl might buckle and not make a perfect fastening.

Referring now to Fig. Q, I have shown the relative positions of the burr and rivet just before the rivet pierces the material, and it will be seen that the rim 2 engages the cloth or material 5 and forces the material slightly within the hub l, while the continued pressure will force the prong through the material and up into the hub.

After the burr, rivet and cloth are in the position shown in Fig. 2, a properly designed heading pin (not shown) descends to force the several parts in the position shown in Fig. 5, deforming the rivet 3 and filling up the entire hollow hub, and at the same time slightly rounding or heading the hub as at 6, and also causing the prong 3 to spread or enlarge at its top as at 7. The deformed prong, now being slightlv en lli) larged at its end and encased, will prevent the deformed burr from ever being pulled away from the rivet. At the same time, the flange 2 of the burr compresses the cloth or several layers of' cloth against the under surface of' the rim t of the rivet, tightly holding the material together.

Referring now to Figs. 3 and 4, there is shown a slightly modified form, or to be sligitly more accurate, the burr is slightly modified before the final heading operation takes place.

In this instance, the burr 8 as shown in Fig. B is similiar to the other burr, but as the plunger (not shown) comes down it will carry the burr or eyelet to the garment and as soon as the flange presses down on the garment, a prick point on the header pin (not shown) marks or makes the indentation in the burr and holds it true as the rivet and burr are headed, As shown in Fig. 4L, the rivet lO when headed, will he slightly enlarged at its upper end, as at 1l, thus )reventing the burr from pulling away from the rivet and the two parts forming substantially a unitary structure.

Also, by providing this indentation `in the crown of the burr, there is no possibilityY of the burr slipping or moving out of its true alignment during the heading operation.

From the foregoing it will be seen that I have provided an extremely eflicient fastening means comprising but two parts, both of which are deformed when the parts are attac ied or headed. The relative length of the hub of the burr and the prong of the rivet are such that the prong will, in its final state, completely fill up the hollow hub, and due to the shape of the header, the sides of the hub will slope inwardly towards the base and engage the inwardly sloping sides of the deformed prong, thus making it impossible for the fastening means to ever pull apart.

I am aware that it is old in the art to provide buttons comprising a base, and eyelet, a burr and a rivet, wherein the rivet passes through the base and into the eyelet to secure the `button to the cloth, and I do not Claim my invention as such.

1What I do claim,however, and desire to secure by Letters Patent is 1. A fastener comprising a rivet and burr, the said burr having a hollow hub and a rim at its one end, the length of the rivet being greater than the depth of the hub, 'and the said rivet and burr headed to stunt the rivet and to Contact the burr just above the rim and to cause the rivet to be contracted near its lower end and force the displaced metal of the rivet into a solid bulbous end completely filling the former space within the hollow hub.

2. A rivet fastener comprising a rivet and burr, said burr comprising a` hollow hub and an outstanding flange at its lower end, said rivet also provided with a headed flange, the length of the rivet being greater than the length of the hub, the two said flanges adapted to clamp an article between them, the hub and rivet deformed to stunt the rivet and to contract the burr just above the rim and to cause the displaced metal of the rivet into a` solid bulbous end completely filling the former space within the hollow huh, and a depression in the top of the burr for centering the burr during the deforming operation.

In testimony whereof I affix my signature.
