' settingtoolQ EYELET Application filed October 5,1923, Serial No. 666,862, and'in Germany September 13,1923. Renewed L A :n rn 9, 1927., I I r This inventib'nrelates to eyelets and isidisclosed herein with particular reference to eyelets especially adapted to be'used for in visible eyeleting in the manufacture of boots and shoes. 7 g V 1 p In order to insure that the .outer layer'of the stock will be properly forced past the clenching shoulder of the setting tool in the. insertion of invisibleeyelets, it is an object of the present invention to provide an improved eyelet having the end of its barrel'f-ormed to provide effective means to push the stockin which the eyelet is to be inserted along'the pilot ofthe setting tool and ultimately to force the outer layer of the stock past the clenching shoulder of the tool. Further objects of the invention are to provide an eyelet for invisible ,eyeleting which will be satisfactory in the best grades of shoes and whichcan, at the same time, be produced in quantity at a cost which will permit its .usein-shoes of anytype or grade in which. it is desired to insert invisible eyelets.

. With these objects in view, the herein dis closed eyelet is provided with a blunted, polygonal or scalloped end providinga plurali ty of outwardly projecting, stock-pushing portions arranged to engage the workat points rem-ovecl fro1n the lacing hole, alternating with a pluralityof portions arranged to engage the edge of the lacing hole, this formation being such as to insure that the upper leather is properly forced past the clenching shoulder of the setting tool and also facili tating the ready passage of the end ofthe eyelet barrel through thelacing holeand the clenching thereof between adjacent layers of In order to cause the prongs formed when the eyelet bursts to curl progressively outwardly and downwardly toward the flange of the eyelet as they pass the clenching shoulder of the setting tool, the portion of the barrel of theillustrated eyelet at and adjacent to its entering end and extending a substantial distance towards the flange of the eyelet is of a non-tapered formation so that the eyeletbarrel has a long bean ing upon and closely embraces the pilot of the While the invention is disclosed herein in connection with an. eyelet particularly intended for invisible eyeleting in the manufac ture of shoes, it should be understood that in various of its aspects it is not so limited,

With the above and other objects in view,

the invention will now be described in connecti'on with the accompanying drawings and view, respectively, oftheeyelet prior tothe performance of the final upsetting and blunting of the end of its barrel;.

Fig. 6 is a sectional View illustrating the relative position of the setting tool, the eyelet and the stock at a selected stage during the clenching ofthe eyelet; H V Fig. 71s a longitudinal section of a die usedin the scalloping and scoring of the eyelet barrel; f

Fig. 9 is a perspective view of a punch which co-operates with the die of Fig. 7 to. scallop and'score the eyelet barrel;

Fig. 10 is a longitudinal section through the punch, die and eyelet during the scallop-' 0 ing and scoring operation, indicating also in dotted lines the position ofthe punch relatively to the die at the conclusion of that operation; I

Fig. 11 is a cross section on the line 1111 of Fig. 10, with the eyelet omitted; and

Figs. 12 and 13. illustrate the upsetting and blunting of the entering end of the eyelet V v i 7 tween the successive scallops. At its entering end the eyelet barrel is upset and blunted,

as show'nat 108, so as to provide a flat'or 7,100

' layers of a shoe upper along the plane work-engaging end surface of a form effective as a pushing member to push the pilot 110 of an invisible eyeleting tool 112 (Fig. 6) and ultimately to force the outer layer 114 (that is, the upper leather) past the clenching shoulder of the setting tool; The" scalloped formation of the entering end of the eyelet barrel is of material assistance in forcing the outer layer 11a of the stock past the clenching shoulder 116 of the setting tool 112 in that it provides the entering end of the barrel with effective pushing portions 118 (Fig. 6) at and adjacent to the apexes of the scallops which engage the material at points or over an area removed from the lacing hole thereby, during the relative movement of the eyelet and the setting tool 112, forcing the outer layer of the stock past the clenching shoulder'116 of the setting tool. On the other hand, this polygonal or scalloped formation also permits portions of the end of the eyelet barrel to engage the edge of the lacing hole and to embrace closely the pilot 110 of the setting tool 112 so as to facilitate the passage of the end of the barrel through the facing or lining 119 and the eyelet stay 120 of the shoe upper, the abutment 122 preventing the up per leather 11 from being forced too far past the clenching shoulder 116.

As illustrated, this scalloped formation extends more than halfway from the entering endtoward the flange of the eyelet. Morethe flange.

over, the portion of the barrel of the illus trated eyelet at and adjacent to its entering end, and extending approximately halfway to the flange of the eyelet, is of a substantially non-tapered formation, the remainder of the barrel flaring at a considerable angle toward Thus the internal diameter of the eyelet barrel, measured on any longitudinal plane of cross-section, is substantially uniform at all points in said plane between its extreme end and the beginning of the flaralso causes the hole through the clenched eyelet to be larger than the hole through the entering end of'the barrel of the unclenched eyelet, since a substantial part of the flaring portion is split and turned back when the eyelet is clenched. Accordingly there is no danger that the hole through the clenched eyelet will be too small to permit the passage of the tip of a shoe lacing.

v This novel eyelet may conveniently be 108, Fig. 13.

formed from a blank having the flange and barrel of the ordinary eyelet, by scalloping and scoring the barrel, as indicated in Figs. 4 and 5, by tools illustrated in Figs. 7 to 11 and by subsequently upsetting and blunting the entering end of the barrel, as shown in Figs. 12 and 13, as will be more fully described.

In Figs. '4', 8, 10 and 11 is shown a hollow die member 124 formed with a series of ribs 126 separated by grooves 128, the ribs 126 tapering off at the entering end of the die, as shown at 130 (Fig. 7), thus forming an enlarged entrance 131. Conveniently at itsentering end the die is provided with a recess 132 adaptedto receive the flange of the eyelet blank to be operated upon. A punch 134, illustrated in Figs. 9, 1O and'll, is used in cooperation with die 12 lto scallop and score the eyelets. This punch is itself scalloped, as clearly shown in Figs. 9 and 11, the successive scallops meeting and forming cutting edges 136. The entering end of punch 134 is tapered to facilitate its introduction into the barrel of an eyelet which has previously been introduced into die 124. as shown in Fig. 10. shoulder 137 which co-operates with recess 132'of'die 124 properly to limit the movement of punch 13a relatively to an eyelet operated upon. The punch 13% enters the portion of the eyelet barrel adjacent to the eyelet flange freely and without obstruction but, as it passes toward the smaller entering end of the eyelet barrel, edges 136 of the punch score the interior of the barrel, finally cutting all the way through the barrel at the entering end thereof. At the same time the barrel is scalloped, being forced into the space (indicated at 138, Fig. 11) between the punch 13 1 and die 12 1. Punch 134i is passed through die 124i approximately to the position indicated in dotted lines at 1&0 in Fig. 10, after which it is withdrawn leaving thejeyelet in the con dition shown in Figs. 1 and 5, with a thin,

sharp edge 1 1-2 at its entering end. After this the eyelet is placed upon a spindle 14A (Fig. 12) having a shoulder 1&6 arranged to support the flange 100 of the eyelet adjacent to the lacing hole and having a tapered portion 1418 terminating in a cylindrical portion 150 arranged substantially to fill the entering end of the eyelet barrel. Cooperating with spindle is a die 152 having a hole therethrough of a size to be a good working fit on the cylindrical portion 150 of spindle M l. lVith the eyelet supported upon spindle 1 1%, as indicated in Fig. 12, die 152 and spindle 144 are, given relative movement so as to force die 152 against the end of the eyelet barrel supported upon the cylindrical portion 150. of the spindle, upsetting and blunting the end of the eyelet barrel, as shown at Die member 152 is then withdrawn and the eyelet removed from spindle Punch 18a is provided also with a 144, after which the substantially completed eyelet may be subjectedto any desired finishing operation. This method of manufacturing eyelets is'not claimed herein, since it 30, 1925, as a division of this application. e

By reducing-the depth'of grooves 128 in die 124 and by correspondingly reducing the size of punch 134, the depth of the scalloping of the eyeletmay be reduced. Indeed this may be carried to such anzextent that the entering end of the eyelet-barrel will take the form of a polygon each of whose sides is a straight line instead of the curved line shown in Fig. 5.- Eyelets so formed,v or scalloped eyelets formed as shown in Figs.'4 and 5 Without the upset or blunted end, are more effective than the sharp-ended circular eyelets of the prior art in pushing the layers of the shoe upper along the pilot of an invisible eyeleting tooland in forcing the upper leather past the clenching shoulder of the tool, since portions of the end of the'eyelet barrel engage the stock at points spaced from the lacing hole,

though such eyelets are less effective in this respect than the eyelet of Figs. 1, 2' and 8. However, since such eyeletsvare cheaper to manufacture (the upsetting and blunting being omitted), and since they operate satisfactorily with many kinds of stock, they are of real utility in the art and are considered to be within the scope of the present invention.
