FASTENING-INSER'IING MACHINE.

Application filed Cctober 2,- 1920. Serial No. 414,281.-

This inventionrelates to fastening inserting machines and is illustrated herein as embodied in a fastening inserting machine which prepares the work for the insertion of other fastenings.

Insoles utilized in the manufacture of certain types of shoes are provided with lips or ribs which stand up from the body of the insole and serve as means for the attachment ofotherparts of the shoe, as for instance, of the upper or ofthe' upper and welt. The rear ends of such an upstanding rib or lip are located in proximity to 'the breast line of the heel, and for some distance forward of this line in the shankof the shoe the upper has a very considerable tendency topull the lip'or riboutwardlycausing afullness or slack in theupper of the completed shoe.

One of the methods by which the difficulties above mentioned are overcome involves the attarhnient of the rear ends of the lip or rib to thebody of the insole by the insertion fastening maybe inserted and properly vclinched. In many casesthe lip or rib of fastenings. As a preliminary step in the operation it is necessary to bend the rear end of the lip or rib inwardly or backwardly against the body of the insole so that a resists bending to such an extent as to make it a difficult operation to perform by hand or by any machine heretofore known.

' Inview of the foregoing, it is an object, of this invention to providea fastening 1n-.

serting machine having improvedmeans for positioning the work or parts of the work relatively to other parts preparatory to the insertion of a fastening or fastenings or preparatory to securingwork parts in the relation in which they are positioned by Said means, which machine will be adapted for performing the rib-bending and attaching operation above referred to. h

To this end and in accordance with a feature of the invention, the illustrated fas- ;tening inserting machine is characterized by the provision of movable means for bending the rear portions of the lips or ribs of insoles back against the bodies of the insoles, and

' holding the lips or ribs thus bent during the insertion of fastenings which permanently holdthe end portions of theribs in that position. Itshould be understood, however,

, that'in various respects, theinvention is not restricted to embodiment int-he illustrated type of machine, or to use in performing Q insolewhich has been bent back, as above stated, against the body of the insole, and, to holditso clamped during the insertioniof a fastening therein. Preferably, and as illustrated, the fastening inserted is a fine wire staple, which is inserted through the insole from its foot-engaging surface, and which, after passing through the 'rib, is clinched upon the surface of the insole. p

In .the illustrative *machine. the anvil which clinches the fastening driven through the insole, by thedriver operates by a hammer blow to ensure the completion of the bending of the rib or lip which has been turned over by the bending slide and to hold the rib during the fastening insertion and clinching operation.

Other features of the invention and other combinations of parts will be described in the detailed specification and pointed out in the appended claims.

In the drawings Figure 1 me view in side elevation and par'tlyin section of a staple fastening inserting machine embodying the invention;

Fig. 2 is a detail 'view in perspective showing the insole clamping and rib bending devices; and I Fig.3 is a section along the line 3-3, extendedpin Fig. l and looking toward the left in said figure. I

The invention is illustrated as embodied in a fastening inserting machine of the general type. disclosed-in United. States Letters Patent No. 1,1657%, granted December 21,1915, on-the application of J. W. Cosg-rove. Referring to the drawings thereference character 4 designates the outside former, which operates tobend the staple wire over the inside former 6, the latter being reciprriicabhe' vertically into andout lit of operative relation with respect to the outside l'ornier. Alter the staple has been formed it is carried :lorwardlv to the right in l i gure l. lay a continued movement of the outside former and subsequently driven by the driver 8 which operates in a groove in the outside former in accordance with aconstruetiou and arrangement that is very common in machines for inserting staple fastenings.

While the machine at rest the anvili spaced from the outletio'f the :tastonine guiding nozzle and is operated to clamp the work against the nonale andto clinch the :lastenin e' while txh driver is forcing" the name through the work For moving the anvil in properly tinted relation to the outside former and to the driver, means is provided tor reciprocatin' the anvil carrier 2-36, the said means 00111 11;; preferahly lever 40 pivoted at l2 the machine frame and having its upper end COIlllLtJlt-Efil lrv an extensible link ll to an arm lti proiecting from the lever 52a ill will he noted that the link ll is pivotally connected at: ill to the lever lt and aleo pivotally connected to the arm 46, a plurality oi such connecting points being provided on the arm l6 so as to provide for adjustments in the connections by which means the lever l0 may be given operative movement of greater orlese extent. Pivot-ed to the lever id at is a link il whicn extends; through the anvil carrier Flo and has a sprinu 6 eurrounding the link between an outer surtace oi? the anvil carrier and a washer 58 secured to the end of the link so that tho anvil carrier is pulled yieldingrly in the di-. rection to, l'orce the anvil against the work durin clinching operations. The machine thus far. described is substantially like that shown. in said Letters Patent: and for a more complete description of the operative parts ofthe machine reference should he had to sa d Letters Patent.

arrangement being vsuch that operation of the lever 4L0 will move the anvil through the greater part of the distance it has to travel,inapproaching the .work before the bending slide 84 is operated. In Fig. 1 the anvil 1s shown ust about to engage the msole, prlor to which the bending slide moves downwardly to fold the outstanding lip or rib. of the insole inwardly from the edge.

and down against. the body thereof where it is clamped at the point of fastening insertion by the anvil, as shown in Fig. 2, and held during theinsertion of the fastening which is clenched against the end surface of the anvil. The anvil operates with a hammer blow to ensure the complete bending of the rib-or lip and to clinch the fastening securely. At the end of the cycle of operations, the anvil moves away from' the nozzle and the bending slide 84 is with-' drawn upwardly, as the lever 40 moves to the right in Fig. l, the insole being. released from the clamping members upon retraction of the anvil carrier with the plungers 76 .carried'thereby. The insole is then rotatedto project theheel end in a direc tion opposite to that shown in Fig. 2, and the other edge of the insole upward to present therear end portion of the other lip or upstanding rib just above the line of fastening insertion which may be gaged by a shoulder on the nozzle extension 68 or located with reference to the gripper or clamping members 70; Vith the insolethus reversed-that is, with the heel end thereof pointing to the left. in Fig. 2, the right fork of the bending slide 8 may be depended upontoeifect the bending of the rib down uponthe insole so as to insert the fastening near the end of the rib. Operation of the machine results as before in bending the ribdown upon the body of the insole and in inserting a fastening. to'hold it in its shaped or bended condition. Ina preferred 1 construction a gage '96 is provided for '10- extension 68 whereupon the gage plate 96 may be moved upwardly or downwardly so as to adjust it in accordance with the width After the. gage of the feather on the insole. plate has been moved to the desired position, the bolt 7a is turned in the opposite direction to cause the arms of the extension 68 to grip or clamp the plate 96, holding it firmly I in adjusted position. As before pointed out extensions of the bolt 74 support the gripper or clamping members 70 for loose pivotal movement. Since the insole is firmly clamped against the flat end of the nozzle prior to the operation of the bending slide 84:, the work is held securely in position during the bending operation andinsole ribs which have heretofore been the causefof considerable trouble because of stiffness, are bent easily into proper position and securely attached in the desired relation to the body of thein'sole.
