Application April 2, 1952, Serial No. 280,123

1 Claim. (Cl. 24-152) This invention relates to upholstery rings, often called hog rings, and has for its main object the provision of a ring of the class described which can be closed with no points exposed.

Another object is to provide a ring in which, when closed, the sharp edges of the extremities lie at along the adjacent parallel leg of the ring.

A further object is to provide a ring which is, when closed, substantially triangular in shape, said shape being obtained by bending the ring at the center of its crown. This can be done with minimum effort by means of the usual plier tool employed.

Other objects and advantages of the invention will be apparent from the following specification where, by way of illustration, a preferred embodiment of the invention is disclosed. It will be understood, however, that many changes can be made without departing from the inven tion as defined by the appendant claim.

In the accompanying drawings:

Figures 1 to 8 inclusive, are views as hereinafter described of a ring embodying the present invention.

Adverting now to the improved ring constituting this invention, and referring to Figure 1, it will be seen that the body 10 of the ring points 11, 12 formed by the outwardly beveled surfaces 13,14, and that the body of the ring is bent to displace the points outwardly so that they will pass each other, as shown in Figures 2 to 8.

When such a ring is squeezed or closed by the pliers commonly used for that purpose, where the points 11, 12 are brought together as shown in Figure 3, the points slide past each other, and the ring closes as shown in Figure 4, there being no exposed sharp points as the at sides of the ends lie against the underlying parallel leg of the ring as shown in Figure 5.

By referring to Figure 6, it will be noted that points 11, 12 slide past each other to penetrate the fabric 15, 16 and shear a clean path through which they pass without tearing or laterally displacing the fabric and without pinching same between the beveled surfaces 13, 14. It will be apparent that the beveled ends form a shear, the edges of points 11, 12 forming in effect blades that actually cut the fabric to form therein an aperture closely fitting the transverse contour or section of the ring. This obviates the tearing action which often occurs with prior art rings.

By referring to Figure 8, it will be seen in enlarged detail that as the ring 10 is closed, the points 11, 12 slide against the side surfaces 17, 18 of the ring and that the points are not exposed. Thus by displacing the beveled points of the ring outwardly from the center plane of the ring as shown in the Figures 1 to 8, inclusive, the body of the ring being of suitable material such as steel wire, the structure assures that when the ring is closed, the adjacent surfaces 19, 20 of the ends are.` held at against each other, being forced into this position by the normal closing action of pliers. A further advantage of the improved structure as described is that as the device is closed, ends of the legs do not abut each other as in some prior devices, thus requiring less force for proper closing and preventing any tendency to distort the body of the ring by excessive end pressure. The invention thus combines the advantages of smooth and easy application, lack of distortion, elimination of hazardous projecting points, and preservation of the fabric.

What is claimed is:

An upholstery clamping ring comprising a normally open body of comparatively rigid malleable metal wire and comprising an arcuate central portion and angularly directed end portions terminating in axially spaced and substantially aligned piercing points for conjointly piercing webs from opposite faces thereof, said points being formed by beveling the ends of said ring, said bevels sloping outwardly, whereby the ends thereof will slide on each other with said points lying on the outside of the ring and against the body thereof when the ring is closed.
