26 Claims. (01. 24-1512) This invention relates to the pointed spurs or wire articles such as double pointed pins and the like, the pins being designed to fasten seat covers to the upholstery fabric of automobiles and the like.

In pins with single legs, a pointed spur has been provided heretofore at the free end of the wire forming the head of the pin to prevent the pin from working loose from the seat cover. While heads of various kinds may be formed intermediate the pointed ends of a double pointed pin, no free wire end can be provided in the head, from which end a spur might be formed. con sequently, such spurs have heretofore been inade, not from the head of the pin, but from the sheet material of the cap with which the head is covered with consequent disadvantages, or else the spur has been completely omitted. Where the spur is on the "cap, not only is additional material required but care must be taken to locate the spurbetween the legs of the pin accurately on assembly of the cap and pin at additional ex; penditure or time and labor and increased cost (if manufacture. A

The present invention therefore contemplates the provision of an elongated pointed spui at any paint desired ina length of wire of any desired dross-sectional shape and of any desiredoutline, seen as the head of a double pointed pin.

The invention further contemplates the prm vision of a generally pointed or edged spur, integral with and partly severed from the wire of which a double pointed pin is made, and suits ably bent from the wire to project at the required angle to' erform its function, whereby the spur may economically be formed at the proper point in the head itself of such pin, regardless of whether the head is to be later capped or not,

and the can if used, may nevertheless be easily,

secured to the head in the usual manner as if the spurs were not present. t

The various objects of the invention will be clear from the description which follows and from the drawings, in which 7 Fig. 1 is a fragmentary rear elevationalyiew of one form of a typical capped double pointed 151i"! illustrated as inane of square 'wire and "Show ing a pair or spurs split or sheared from a pertien of the substantially U-s'h'aped head or the pin, the legs of the pin being partly broken away to show the underlying head.

Fig. 2 is a vertical sectional view thereof. Fig. 3 is a fragmentary view similar to Fig.1

! another form of a typical capped, double.

pointed pin made of round wire and showing a Fig. 6 is a vertical sectional view, similar to Fig. 2, of the pin of Fig. 5.

Fig. 7 is an enlarged front elevational view or a portion of a length of round wire, having a flattened part from which the spur is sheared and bent. I

Fig. Sis a side elevational view of Fig. 7.

Fig. 9 is an enlarged side elevational view of a portion of a length of rectangular wire bent into partly circular form and having an integral spur cut therefrom.

Fig. 10 is a front elevational view of Fig. 9.

Fig. 11 is a front elevational view of a portion of a length of elliptical wire having a spur cut therefrom.

Fig. 12 is a side elevational view of Fig. 1 1.

In what follows it will be understood that any or the pins of Figs. 1-6 may be made of wire of any desired cross-sectional shape such as square, round, rectangular, elliptical or the like, that the heads of any of the pins may take any desired form such as U-shape'd with straight sides (Fig. 1) U-shaped with circular sides (Fig. 3) or inverted U-shaped with side bends so that the head is generally W-shaped (Fig. 5), that any desired number of spurs may be formed from any of the heads of the pins illustrated, such as one in Fig. 3 or two in Figs. 1 and 5,, that the spurs may be severed from corresponding (Fig. 5) or non=corresponding (Fig. 1) portions of a symmetrical pin head, that the spurs may be of any desired length and shape and may be bent at any desired angle laterally or transversely to the general plane of the adjacent material or of the wire article, and that the terms point and pointed as used herein, are intended to refer to a sharp edge as well as to a peint of a well known type such as a needle point.

In the form of the invention shown in Figs. 1 and 2, the wire of which the pin is made is illustrated, ,for the purpose of showing a practical embodiment of the invention, as of square crosssectional shape, and the head I!) is illustrated as generally U-shaped, though as above indicated,

the head may be of any convenient shape and the wire of any cross-sectional shape instead of the square wire shown. The legs H and 12 of the pin terminate in suitable points II and I2 and the sheet metal cap l3 engages the bottom part of the head In as well as the bend at the upper ends of the legs, a projection as H! being preferably interposed between the legs to hold the parts firmly in their proper positions.

One or more pointed spurs I5 and 16 are formed from the square wire of the head In by slicin shearing or otherwise severing part of the wire material of the head incompletely away from the pin is retracted after it has been pushed into its operative position through a slip cover and upholstery. The end 46 of the spur opposite its point remains integrally attached to the pin head as hereinbefore described in connection with Fig. 1. The cap 42 may obviously be set on and secured to the head in any rotated position, since the holding flange 41 thereof, though shown partly broken away to expose the second bends 48 of the head, is of uniform width throughout and symmetrical about all its center lines and no irregularities such as prongs or projections occur in the cap.

adjacent wire material and bending the severed part laterally out of the general plane of the head to arrange the resulting spur at the proper angle, in which it is directed toward the legs but extends in a general direction opposite to from the outer edge of the head. It will be understood, however, that either spur may be cut from any edge part of the head as hereinbefore indicated, or from corresponding points as shown in Fig. 5. As shown, to form the spur l5, the

' spur material is severed from the head along a diagonal line or surface I! beginning at the inner edge l8 of the head and extending across the face l9 of the head to a point as H approximately half way between the inner edge l8 and the outer edge 20. Hence the surface I! of the spur is of the same size and shape as the wall 22 of the recess 2i in the head, resulting from the removal and bending of the spur material out of the plane of the head to the position shown in Fig. 2. The spur or spurs are preferably formed simultaneously with the bending thereof, after the length of wire from which the pin is made, has been bent or doubled to form the first bend 29 of the head and before the second bends 23 are made to double the legs back on the head ID.

The spur assumes a position in which it is bent about that end 34 thereof opposite its pointed end 33 and adjacent the end point I1 of the sheared surface I1, said end 34 remaining integrally attached to the wire. 7 7

While the spurs illustrated are shown for clarity slightly spaced laterally from the adjacent material from which they are severed, in practice the spurs are frequently not spread, but are intended to be aligned with the walls of the recess resulting from the shearing operation by which they are formed.

The pin shown in Figs. 3 and 4 is optionally made of round wire having a circular head'40.

generally U-shaped but subtending an angle greater than 180, legs 4| extending from the head and a cap 42. In the form shown, a single spur 43 is sheared from the wire of the head by the single straight but inclined cut 44, similar to the cut I! and similarly made about half way across the thickness of the wire in one direction and completely through the wire in a perpendicular direction. The resulting spur 43 is bent away from the adjacent material toward one of the legs and into a position between the legs, and is directed slightly rearwardly, but extends in a general direction opposite to that of the legs. The spur point 45 is therefore in a position to perform its fabric-engaging function when the In that form of the invention shown in Figs. 5 and 6, as made of round wire, those parts 50 of the generally W-shaped head 5|v from which the spurs 52 are to be out, are flattened in the general shape shown in Figs. 7 and 8 on an enlarged scale, to increase the width thereof and thereby to facilitate the spur-forming operation. The out, shearing the spur from the adjacent flattened material of the wire, may be straight throughout as shown by the cutsurface 53 of Fig. 7, or may be a broken lineas 54,. 55 of Fig. 5, composed of two intersecting straight lines, or of any other suitable shape, as shown for example in Fig. 10. The flattening operation may be performedas the wire is at rest after the first bend 56 has been made therein and just prior to the spur formation. The spurs 52, as in the forms of the invention above described, extend toward the legs, but point in a direction opposite to that of the legs 51. r j

Figs. 7 and 8 show the spurs 58 partlysevered from the flattened part 59 of a length 66 of round wire which has bends BI, 62 therein, the spur 58 being bent out of the plane of the flat-1 tened part 59 at the desired angle .and zbeing attached to said part integrally at-one end 53 and pointed at the opposite free end 64. I

In Figs. 9 and 10, the wire 66 illustrated is of rectangular cross section and is bent into circu-, lar form to show that wire of any suitable crosssectional shape, bent in any mannenmay have an integral projecting pointed spur sheared therefrom according to this invention. The spurforming cut consists of the inclined straight out 61 forming the point 68 at one end of the spur. B9, and the meeting arcuate cut 10 arranged con-; centrically with and approximately half way between the side edges of the wire. The other end ll of the spur is integrally joined to the wire and supported thereby. While the spur in this case is shown as curved in one direction, it will be understood that it may be straightened during the spur-bending operation. I

In Figs. 11 and 12, the portion 13 of a length of wire of elliptical cross section is provided with the pointed spur l4 sheared from the portion 13 by a pair of intersecting cuts as 31, 38. The part from which the spur is severed, may first be further flattened if desired, in the same manner as shown and described in connection withFig. 7, and the spur may be formed at a curved portion of the wire if desired, as shown in Fig. 10. In' any case, the spur is integrally connected with the wire at one end, pointed at the other end,and bent out of the general plane of the wire.. 7,

It will therefore be seen that I have provided a pointed straight or curved projecting integral spur at any part of a length of wire of any cross sectional and peripheral shape, that th spur may be directed inexpensively at a proper angle to the general plane of the remainder of the wire to provide a point at one end spaced froin'the' gsvaeoe wire, while the otheri end remains attached inr l v to h wir h fllphfi l'. ve adapted for formation at thehead of a double pointed capped or uncapped pin wherein no integral spur has previouslyb'een available, that the spur may be formed as an intermediate step intheformation of the pin, and that the" ir'iven v tion .is well adapted for its intended purposesof producing a point for easily piercing or entering fabric or other suitable material on manipulationrof the pin or other article from which" it projects.

While I have shown and described eertain specific forms of the invention, numerous" other forms along the lines of those disclosed herein, will'now be obvious, and other changes may be made herein without departing from the spirit of the invention as defined in the appended claims.
