WORK-POSITIONING: MECHANISM Application filed June 15,

Essex, respectively, and State of Massachusetts, have invented certain improvements in lVorlcPositioning lvlechanisms, o Which the following description, in connection With the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to mechanism for positioning Work such, for example, as shoe stock for the performance of operations thereon, and the embodiment of the invention hereinafter specifically described will be set forth With particular reference to its application to the insertion of fastening-s in toplifts of heels.

In the manufacture of shoes of certain kinds, it is customary to affix a toplift to the heel of a shoe by metallic fastenings inserted adjacent to each of the breastcorners of the toplift and at the back of the toplift respectively. The head ends of the fastenings are visible 011 the tread surface of the heel of the finished shoe, for which reason it is desirable to the end that the heel may present a symmetrical appearance that the fastenings be spaced equidistam'vly from the contour edge of the toplift, and that the fastenings inserted adjacent to the breast corners of the toplift be disposed equidistantly from the breast edge or" the toplift and be spaced from the breast edge of the toplift by a distance bearing a definite relation to the distance by which they are spaced from the contour edge of the toplift, the distance by Which the fastenings are spaced from the breast edge of the top lift being substantially equal to the distance by which they are spaced from the contour edge of the toplift.

In order that fastenings may be inserted symmetrically in heels of different sizes and to attain uniformity of appearance of shoes having heels of varying sizes, it is further desirable that the spacing of the fastenings from the. ed 'es of the heel be proportioned. to the sizes of the heels so the fastenings will be spaced farther from the breast edge and contour edge of a large heel than from the corresponding Specification of Letters Patent.

edges of a anall heel. Accordingly, an important feature of the invention resides in the provision of means for positioning the breast corners of a heel successively at substantially equal distances from the point of operation on the heel and adjustable for dilferent sizes of heels so that the point of operation on a large heel may be disposed farther from the breast edge of the heel than from the corresponding edge of a smaller heel. Preferably, and, in the illustrated construction, the positioning means comprises a plurality of gage members so connected that an adjustment of one of said members effects a corresponding adjustment of the other.

in accordance with a still further feature of the invention, one of a plurality of gage members is mounted for movement by the Work relatively to the other gage member to facilitate the operation on a heel of a machine employing an and feed by which the Work is moved from the position in which it is first presented to the machine prior to the completion of the operation of the machine thereon. Preferably and as shown the movable gage member is normally urged yieldingly toward the other member and is so constructed as to cause its gaging surface to move substantially in the direction of the movement of the work.

In the illustrated embodiment of the invention, the positioning means for the toplift comprises members formed to present shouldered surfacesfor engagementrespectively with the breast corners of a toplift and With other gaging surfaces arranged for engagement with the contour edge of the toplift, the contour edge gaging surface of each of said members being arranged to engage the contour edge of a heel when a breast corner of the heel is presented against the shouldered gaging surface of the other gage member.

Although the invention will be hereinafter described as applied to a machine for inserting fastenings at three points, for example, for attaching a toplift to a heel, it is recognized that the invention is not restricted in its application to such specific use. and it is further recognized that the members and the means for mounting and adjusting them may be modified Without departing from the principles of the in- 1 vention. It is, therefore, intended that the scope of the invention shall be limited only as required by the language of the appended claims. 7 r

' Fig. 7 is a View showing the relative arrangement of the toplift and the gage members for the insertion of a fastening adjacent to the back of the toplift.

The work positioning mechanism is herein illustrated as applied to a fastening inserting machine of the type employed for inserting headless fastenings formed from wire, such fastenings being generally denominated slugs and a machine for in.- serting such fastenings being disclosed in the patent to Casgrain No. 786,190, granted March 28, 1905. As illustrated, the frame 6 of the work positioning mechanism is pivoted to the head 2 of the fastening inserting machine at 4, and slidably mounted in a boss formed on the head 2 of the machine is a spring pressed plunger 8 cotiperating with the inclined surface 10 formed on one of the bosses 12 of the frame 6. The plunger 8 operates normally to retain the work positioning mechanism in its operative horizontal position but yields to permit the frame 6 and the parts carried thereby to be turned downwardly on the pivot 1.

Mounted on the frame 6 are gage members 14; and 16 formed to present shouldered gag ng surfaces 18 and 20 for engagement with the breast corners of a toplift and preferably curved gaging surfaces 21 and 22 for engagement with the contour edge of the toplift. The fastenings are impelled into the toplift by a driver 23, openings being made in the toplift through the instrumentality of an awl 24 to receive the fastenings inserted by the driver. The gaging surfaces 18 and 20 are so arranged relatively to the awl-asto position the toplift in such manner that the and when projected downwardly penetrates the toplift at the point where the fastening should be inserted.

It is desirable, in order to make the dif ferent pieces of work uniform and symmetrical in appearance, that the fastenings be inserted at a greater distance from both the contour edge and the breast edge of the toplift in operating on a relativelylarge toplift than when operating on a smaller toplift. Means are provided for adjusting the gaging surfaces 18 and 20 to adapt the work positioning mechanism for use in operating on toplifts of varying sizes, and we have so constructed the adjusting meansfor the gage members 14: and 16 that an adjustment of one of said gage members to adapt it for use in operating on a toplift of a certain size will effect a corresponding ad justmeut of the other gage member to adapt it for use in oaerating on a toplift oflike size. To this end, the gage member 14 is fulcrumed at 26 on the carrier or plate ,28

slidably mounted in the frame 6, and the gage member 16 is connected to the gage member 1 1 by a pin and slot connection comprising the pin 80 and the slot 31 whereby movement of the gage member .14 is transmitted to the gage member 16. The gage member 1 1 is'adjusted about the fulcrum 26 by means of a handle 32 and is maintained in any position of adjustment to which it may be moved by a bolt or the like 3-1 which passes through a slot in the. plate 28. The pin 30 and slot 31 form a connection between the gage members lt and 16 whereby adjustment of the gage member 14 effects an equivalent adjustment of the gage member 16 and also permit movement of the gage member 16 independently of the gage member 14. for a purpose to be hereinafter set forth.

Fig. 5 shows in full lines the position in which a heel B comprising a toplift A is presented to the machine. As shown,. the breast corner of the heel B isv engaged with the shouldered gaging "surface 20 of the gage member 16. From an inspection of Fig. 5, it will be apparent that if the gaging surfaces 18 and 20 are moved toward each other, the fastening will be inserted in closer proximity to the breast edge ofthe heel than before, whereas, if the gage members 1 1- and 16 are adjusted away from each other, the fastening will be inserted at a in the frame 6 and toothed or corrugated .opposite the handle 42. A spring ie at the end of the shaft 05 is interposed between nuts 46 and the me 6 and erts friction whereby the ier :28 is maintained in any position of adjustment to which it may be moved. From the fore going it will be plain that, if heel of greater size than the preceding heel is to be operated upon, the handle will be manipulated to move the members 1e; and 16 away from each other which will cause the fastening to be in. greater distance from the breast ed 3 heel. The handle 4:2 will also be manipulated to move gage members 14; and 16 rearwardly away from the plane of operation of the fastening inserting mechanism which will increase the distance by which the fastening will be spaced from the contour edge of the heel.

In the operation of the fastening inserting machine, the awlv is moved laterally subsequently to its projection into the work to bring the opening thus made in the work into alinement with the driver Each of the shouldered gaging surfaces 18 and 20 has-a portion arranged transversely of the direction of movement of the work and intersecting with the contour edge gaging surface 21 or 2:2, the angle thus formed engaging the breast edge of the heel when the heel is presented to the fastening inserting machine indicated in Figs. 5 or 6. In order to permit movement of the work by the aw]. we have so mounted the gage member 16, which is carried by that side of the carrier 28 toward which the work is moved by the a-wl. as to permit said member 16 to be moved. by the work inde pendently of the gage member 14;, To this end, the gage member 16 is fulcrumed at 4L8 on the link 50 which is in turn fulcrumed at 52 to the gage slide or carrier 2-8. The link 50 and the gage member 16 carried thereby are normally urged toi'vard the gage member 14L by a spring 5% which yields to permit movement of the member 16 when the work is fed by the awl. Movement of the gage member 16 toward the member 14: is limited by stop 55 Fig. 2.

The awl moves in a substantially straight line and in order that the work may be effectively guided and supported while it is being fed by the awl, we so control the movement of the gage member 16 as to cause the gaging surface 20 thereof to be moved substantially in a straight line and parallel to the path of movement of the aw]. Thus the inclination of slot 31 in arm 56 of the gage member 16 is such. as to prevent substantial inward or outward movement of the gaging surface 20 as link5,0 is swung about its pivot 52. against the end of the slot in the arm 56 of the member 16 limits the movement of the gage member 16 under the impulse of the spring and thus determines the normal positions of the gaging surfaces 20 and 22.

A horn 58 may be provided for supporting the heel against force exerted thereon by the fastening inserting mechanism.

The operation of the/device will. heapparent from an inspection of Figs. 5, 6 and lhe heel m. be presented to the fastening inserting mechanism in the position shown in :T l lines in Fig. 5, following which the awl penetrates the heel at the point indicated by the upper small circle defined by a full line and moves it and the gage member 16 to the positions shown in broken lines in said figure, the point of fastening insertion being indicated by the lower circle defined by a broken line. Analogously, the full lines in Fig. 6 indi- 7 of the drawings.

cate the position in which the heel is pre-. sented to the fastening inserting mechanism for the insertion of a fastening adjacent to the other breast corner of the heel, and the broken lines indicate the positions to which the parts are moved by the aw], the lower circle indicating the point of fastening insertion. In Fig. 7 is indicated in full lines the position in which the heel is first pre- Thepin 30 acting sented to the fastening inserting mechanism 7 for the insertion of a fastening adjacent to the back 0 the heel, the parts being moved from full line position to broken line position by the aw]. following penetration of the work by the awl. In each case, the gage member 16 is moved. backwardly in opposition to the action of the spring 54: to permit movement of the work from the position indicated in full lines to the position indicated in broken lines. It will be understood that the order in which the several fastenings are inserted may be varied at the will or convenience of the operator.
