2 Claims. (Cl. 21815) This invention relates to eyeleting machines and more particularly to raceways as used in such machines to supply eyelets having oblong barrels to a spindle of corresponding shape carried by one of the eyelet-setting tools. The eyelets illustrated herein have barrels of oval cross-section and the invention is intended to provide for handling not only eyelets of that type but also eyelets having barrels of rectangular oblong shape.

In providing shoe uppers with oblong eyelets for the lacings, it has heretofore been the practice to arrange such eyelets in the relation illustrated, for example, in United States Letters Patent 1,722,286, granted July 30, 1929, on my application. According to the disclosure in that patent, the major diameters of the eyelet barrels lie in a line parallel with the adjacent edge of the upper over which the lacing is intended to extend, but a demand has now arisen for an eyeleting machine that will place the eyelets so that their major diameters will lie at right angles to the lacing edge of the upper.

In all former raceways for handling oblong eyelets the eyelet-guiding channels have open de-' livery ends through which the. eyelets may be Consequently, an object of the present invention is to provide a raceway of the type that may be operated with sidewisereciprocation to supply oblong eyelets to an oblong spindle of which the major diameter lies at right-angles to the lines of reciprocation of the raceway. The expression oblong eyelets is intended to characterize the cross-sectional shape of the barrels of the eyelets without regard to the shapes of the eyelet flanges and is intended to include both oval and rectangular oblong shapes.

The raceway illustrated herein is like former raceways in that its eyelet-guiding strips are spaced according to the minor diameter ofoblong barrels, wherefore the major diameters of the barrels are maintained approximately parallel with their path of travel therein, but the raceway differs from prior raceways in that its.

delivery end is closed but has provisions for re moval of oblong eyelets from one side thereof while the major diameters of the eyelets lie at right-angles to the lines of reciprocation of the delivery end. For this purpose a wide notch is 5 formed in one side of the raceway to clear the spindle, and herein lies the problem of maintaining control or the eyelet at the delivery end.

' The width of the notch must exceed the major diameter of the spindle, and the flange of the eyelet must bridge the notch. The provision of notch of large enough dimensions leaves so little supporting surface for the flange. of the eyelet that other means are required to prevent the eyelet from tipping and falling through the notch.

To satisfy this requirement the invention provides a spring-biased member arranged to guide the leading eyelet in the raceway across the notch by engagement with a major side of the barrcl. This guiding member is, in effect, an extension of the guiding strip that terminates at the notch to clear the spindle, and although it projects only part way across the notch, its extent of projection is enough to maintain the barrel upright until the flange of the eyelet bridges the notch and finds support at the opposite side thereof. The eyelet is thus prevented from tipping as it slides across the not i. Another spring-biased member located at the opposite side of the notch projects toward the one firstmentioned, each of them partially closing the gap through which the eyelet barrel is finally removed, and both of them being effective to maintain the eyelet in spindle-receiving position.

Referring to the drawings,

Fig. 4 is a perspective view of a portion or" an eyeleting machine of the type more fully illustrated in United States Letters Patent 1,722,286 and particularly the raceway-operating mechanism thereof; and 0 Fig. 5 represents a typical example of work such as a quarter of a shoe upper in which. onlong eyelets have been. inserted in accordance with the provisions of the raceway illustrated herein. 5

The raceway is designed to be mounted and operated according to Fig. l in the patent abovementicned, which figure is reproduced in the present drawings as Fig. 4 with appropriate changes such the substitution of the new type of raceway, a corresponding arrangement of the setting tools, and omission of certain parts not necessary for we purposes of the present disclosure. The raceway assemblage has provisions for mounting it on the left-hand side of the frame $3 to which it is connected by a vertical fulcrum pin ii. This mounting enables the delivery end of the raceway to be reciprocated sidewise in lines indicated by arrow A in Fig. 1, its movement to the left serving to carry an eyelet into register with the spindle l2 of an eyeletinserting tool i3, and its movement in the opposite direction serving to remove the eyelet from the raceway and to clear the path of the tool I3. As shown in 1, the spindle l2 and the barrels id of the two eyelets are of oval cross-section.

The raceway comprises a base plate l5 and two cooperative eyelet-guiding strips l6 and I! mounted thereon but spaced therefrom as usual in such constructions. The guiding edges of the strips are spaced one from the other in accordance with the minor diameter of the oblong barrels M. The arrow B represents the direction in which the eyelets travel in the raceway. A notch 28 is formed in the base plate E5 to receive the spindle i2 and its open end is at the left to permit the raceway to move to the right after delivering an eyelet to the spindle. Considering the side 2! of the notch as the nigh side because the eyelets approach the notch from that side, the guiding strip I6 is terminated at the nigh side but the strip i? is longer to guide the eyelets across the notch. The flanges of the eyelets are seated on the base plate i5 and the barrels extend upwardly therefrom. The eyelets are adequately controlled by the strips (6 and i1 until they reach the nigh side 25 of the notch, but since the eyelets must slide a considerable distance beyond the end of the strip IS, the latter is not effective to keep the flanges of the eyelets on the ledge 21 of the base plate as shown in Fig. 2 or to maintain the barrels M upright. It is therefore necessary to provide other means to maintain these conditions as the eyelets slide across the notch, for if they are permitted to tip or slide to the left, they will fall through the notch.

Consequently, to insure adequate support and control of the eyelets at this point, the raceway is provided with a spring-biased member 22, the eyeletengaging portion 23 of which is more clearly shown in Fig. 2. This portion 23 lies on the upper surface of the shorter strip l6 and serves. in effect, as an extension thereof, although it projects only part way across the notch 20. Its extent of projection is suflicient, however, to maintain the flanges of the eyelets on the ledge 2? and to maintain the barrels i4- upright until the leading edges of the eyelets have crossed the notch and become lodged on the base plate at the far side of the notch, as illustrated in Fig. 3.

The spring-biased member 22 spans the strip i7 and is seated upon the base pate !5 to which it is connected by a pivot stud 2d. The spring bias is provided by a light tension spring 25 one end of which is engaged with a hole in the member 22 and the other end of which is engaged in a hole in an ear 25 formed on or affixed to the base plate. As represented in Fig. l, the eyelet-engaging extremity of the member 22 is broken away to avoid obscuring the nigh side 2| of the notch; but the normal position of the portion broken away is represented by dotted lines. A stop 24 is provided to prevent the eyelet-engaging portion 23 from being projected too far across the notch 20.

When an eyelet has advanced to a position in register with the notch 28, its barrel is arrested by a stop 30 which, as shown in Fig. l, is provided by a shoulder formed at the delivery end of the guiding strip 17. Turning movement and escape of the eyelet at this point are prevented by the tip of a spring-biased member 38 that projects part way across the notch 20 toward the portion 23 of the member 22. The gap between the tips of the members 22 and 3| is slightly less than the major diameter of an oblong barrel I 4 (see Fig. 3) but an eyelet once lodged as last described can be removed from the raceway by the spindle I 2 when the raceway is moved to the right. The barrel I4 then forces the members 22 and 3| away from each other, but they close the gap before the next eyelet in the raceway requires their control. The member 3| is seated on the base plate l5 and connected thereto by a pivot stud 32. A compression spring 33 maintains it normally in the position shown in Figs. 1 and 3.

When an eyeleting machine of the type illustrated in the patent above-mentioned is equipped with a raceway constructed in accordance with this invention and with oblong eyelet-setting tools correspondingly arranged, it wi l insert the eyelets in the relation pictured in Fig. 5. In this figure 34 represents a portion of a shoe quarter and 35 is the lacing edge thereof. The major diameters of the eyelets lie at right angles to the edge 35. This edge is the one by which the work is guided while the machine is in operation.

Referring to Fig. 4, the eyelet-inserting tool 13 is afiixed to the upper end of a vertical bar 38 that inserts the eyelets with upward movement, the operation of the bar being derived from a power-driven camshaft 38 through the medium of a lever 39.

A horizontal work-supporting table indicated at 3B is provided with an edge-gage M and with a hardened steel punch-block 42. A combined punch and setting tool 43, of oval shape corresponding to that of the tool I3, is carried by an upper bar 44 to which vertical reciprocation and sidewise reciprocation are imparted by coordinated mechanisms not shown herein but which produce a four-way motion of the tool 45%; viz., first, a downward motion against the punch-block; sec- 0nd, at sidewise work-feeding motion to the left which places the tool 43 in alignment with the tool I3; third, upward movement to retract the tool 43 from a clenched eyelet; and fourth, a sidewise movement to the right to complete the cycle. The tool 43 dwells at the completion of its workfeeding stroke while the lower tool i3 inserts an eyelet and clenches it.

The raceway is affixed to a carrier and this carrier is the element connected to the frame ID by the vertical fulcrum pin H. The motion for reciprocating the delivery end of the raceway sidewise is derived from a cam 46 carried by the shaft 38 and is communicated to the forward end of the carrier 45 by a. train of connections compris-- ing a lever 48, a, link 49, a bell-crank lever 50, and a link 51. The lever 53 is suspended from a horizontal fulcrum H but the bell-crank lever 50 is mounted on a vertical fulcrum.

Since oblong eyelets are used only for visible eyeleting and since machines of the type herein disclosed are organized to insert the eyelets below rather than above the work, the operator places the lining of a shoe quarter uppermost for this kind of work.

Having described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:

1. An eyeleting machine comprising cooperative eyelet-setting tools of oblong shape one of which includes a spindle of corresponding shape, a raceway the delivery end of which is movable crosswise of the major diameter of said spindle, said raceway having a base plate to support eyelets and cooperative eyelet-guiding strips spaced according to the minor diameter of oblong barrels and said base plate having a notch to receive said spindle, one of said strips terminating at the nigh side of said notch but the other extending past the closed end of the notch, two opposed spring-biased members carried by the raceway one of which is arranged to guide the eyelets across said notch to the other member by engagement with their barrels, and means by which said delivery end is reciprocated to present and discharge the eyelets with movements crosswis of their major diameters.
