12 Claims.

The present-invention relates, but not exclusively, to ornamenting machines for perforating, or forming ornamental cut-outs, in shoe upper parts; and more particularly to that type of ornamentingmachine provided with a die having upstanding cutting edges over which the shoe upper part to be ornamented is positioned and upon which the shoe upper part is empaled by a pressingmember located on the side of the shoe upper part opposite'the die.

Heretofore in order to position the shoe upper part to'receive the ornamentations in the desired location it has been customary to provide the ornamenting' machine with a mask having an internal opening: surrounding that portion of the shoe upper part in which the ornamentations are tmbe'formed, some part of the edge of the open-' ing in the mask being shaped to act as a gage for positioning theshoe upper part beneath the E-mask.

Experience has demonstrated that the appearances'of the edges of the perforations or cutouts in'th'e'sh'oe upper part differ on the opposite faces thereof This difference is due to the burnishing ggy-of'the edges of the perforationsor cut-outs on thatface of the shoe upper part into which the cutting edges of the diepenetrate initially and to the formation 'of burs on the edges of the perforations or cut outs on that face of the shoe gowupper part from'which the cutting edges of the die emerge.

Heretoforeit has been highly desirable that the finished'faceof the shoe upper part be the face into'which the cutting edges of the die penegy'trateinitially in order that the edges of the cutouts or'perforations shall present to view in the finished shoea burnished appearance.

In using a shoe part ornamenting machine of the mask type heretofore the face of the shoe part go oppositea the face which is 'gaged by the mask is the one provided with theperforations or cutouts having the "attractive burnished edges. Heretofore in using a mask it has been necessary often to register some portion of the finished face 45*"oftheshoenpper-part with the gaging edge on To: the accomplishment of this object, and such x others 'as may appear hereinafter, the various features of the present invention reside'in certain devices,-combinations and arrangements'of parts, hereinafter described and then set forth in detail in the appended claims, which possess advantages 5 Ii readilyapparentto those skilled in theart.

Other features of the-present invention reside in certain devices, combinations and arrangements of parts, hereinafter described and then set forth in detail in the appended claims, which '10" possess advantages readily apparent to those skilled in the art.

The various features of the present invention will be readily understood from an inspection of the accompanying drawings, illustrating the best 15 formsof the invention at present known to the inventor, in which,

For convenience in disclosure the various features of the present invention are illustrated as embodied in an anvil usable in the cut-out machine of the type disclosed in the patent to Freeman, No. 1,681,033,- August 14, 1928. It will be understood by those skilled in the art, however, that certain features of the present invention are a not restricted to an embodiment in the anviltype i of die, but may be, on the contrary, embodied in fiat bed structures'provided the cutting edges of the die thereof are upstanding and are associated with an overlying mask.

In the illustrated embodiment of the invention the anvil comprises a. fiat plate 1, (Figs. 4 and 5) the upper face of which is provided, rearwardly, withfour posts 8 (Figs. 3, 4, and 5). These .posts support a die base block 9 (Fig. 5) The block 9 is secured to the posts by four screws II] the heads' of which engagecountersinks formed in the top face of a backing plate I I- engaged with the top face of the block 9. The backing plate It supports a die plate l2 which carries a plurality of 7 tubes I3' each provided with an upstanding. (311111.

ting edge 14. The. tubes I3 project upwardly through a soft rubber cushion I15.

Mounted upon the cushion i5 is a stripper plate It having openings therein through which the cutting edges [4 may project when pressure is applied to the exposed face of the stripper plate. The bottom of the stripper plate 56 is provided with four depending posts i! (Fig. 4) which extend downwardly loosely through openings formed in the cushion 15, the die plate l2, the backing plate H, and the base block 9. The upward movement of the stripper plate I6 under the influence of the rubber cushion i5 is limited by four screws 18 (Fig. 4) threaded into the bottom of the posts H. The heads of the screws I8 engage the bottom of the backing plate ll. With this construction the stripper plate l6 may be depressed by the pressing member of the cut-out machine to project the cutting edges i l of the tubes 13 through the openings in the stripper plate and the work supported above it. During this downward movement of the stripper plate the rubber cushion I5 is compressed so that when the pressing member of the cut-out machine leaves the stripper plate it may be returned to its elevated position and thus strip the work from the cutting edges 14 of the tubes 13.

Heretofore in the operation of a cut-out machine of the type described, it has been customlary to support the work directly upon the stripper plate and to clamp the supported work by a mask having an internal opening at least a portion of the edge of which is shaped to register with some portion of the supported work and thus fact as a gage in locating the work properly in position to receive the perforations or cut-outs.

In the illustrated embodiment of the invention the stripper plate 15 is engaged directly, not by the work, but by a mask l9. This mask 19 comprises a flat plate 28 having an internal opening 21 therein (Fig. 2), some portion of which is shaped to act as a gage in locating the work properly in position to receive the ornamentations. The position of the mask 59. with relation .to the cutting edges 13 of the tubes '13 is determined by three pins 22, 23 and (Figs. 1 and 2). The pins 22 and 23 project normally above the surface of the stripper plate: 15. The heads 25 on the bottoms of the pins 22 and 23 ride in chambers 26 formed partially in the base block 9 and partially in the backing plate I l, the chambers being provided with springs 2?, respectively, to maintain the heads 25 pressed against the tops of the chambers 26.

The pin 24 has a head 28 (Fig. 4) and a shoulder 29 both formed upon the upper end of a hollow post 30 loosely mounted in a chamber formed in a post 31 secured to the plate 1' The post 39 is provided with a recess 32 and the post 31 is provided with a screw 33 the point of which engages the recess 32 thus to restrict the post 36 to a limited movement vertically. The post 39 is maintained normally elevated by a coiled spring 34 interposed between the bottom of the chamber in the post 3! and the top of a chamber formed in the bottom of the post 33.

The mask 19 is provided with holes 35, 36, and 31 (Fig. 2) arranged to receive the pins 22, 23, and

24, respectively. The pins 22 and 23 pass loosely through the holes 35 and- 36, respectively. The head 28 of the pin 24 passes loosely through the hole 31 but the bottom of the mask 19 rests upon the shoulder 29.

The work, herein shown as a made upper 38 (Fig. 1) closed by a heel seam 39 and lined with and 36, respectively, in the mask IS. The mask 5 4! is hinged to the mask l9 (Figs. 1 and 2) to facilitate the insertion of that portion of the work to be ornamented between the masks.

Assuming that the finished or grain face of the made upper is directly beneath the mask 41 when the work is inserted between the masks l9 and ll, then some portion of the edge of the opening 42 is brought into registry with some portion of the upper 38 in the ordinary manner of using gaging masks in the perforating or cut-out art. In order to clamp the masks and the gaged work together so that they may be handled as a unit, the mask 4| is provided with two pivoted arms ":5 and 45 (Figs. 1 and. 2) the free ends of which are provided, respectively, with a laterally offset bent clip 4'! arranged-to extend under the mask 19 and clamp the masks and the gaged work embraced thereby. Broadly considered the work may be inserted between the masks l9 and M and gaged, and the masks 1% and ll clamped together with the gaged Work therebetween by an operative other than the operative of the cut-out machine. That is, by employing a plurality of holders, each comprising the masks i9 and il, they may be loaded 30 i and 24, push the anvil into the machine, trip 35 I the clutch, Withdraw the anvil, and remove the clamped masks. leaving the duty of unloading the ornamented work to the operative charged with the duty of loading the masks.

With this construction and mode of operation the operative of the cut-out machine may uniformly position the shoe parts to be ornamented in the cut-out machine so that the finished or grain faces of the shoe parts are directed towards the upstanding cutting edges of the dies thus to 5 insure that the edges of the perforations or cutouts in the finished or grain face of the work shall be burnished and not burred.

In the illustrated embodiment of the present invention the front edge of the mask I9 is riveted at its middle to a yoked-block 48 (Figs. 1, 2, 4, and 5). This block at is swiveled in a block 49 (Fig. 4). To this end the front face of the block 458 is provided with a cylindrical pin 50 journaled in the block as. The pin 50 is held in the block 39 by a screw 5! the point of which engages a peripheral recess 52 formed in the pin 50.

The block 49 is pivoted between yoked arms (Fig. 4) formed on the upper end of a cylindrical post 53 mounted to slide vertically in a cylindrical chamber 54 formed in a post 55 carried by the plate 7. The post 53 is supported yieldingly by a coiled spring 53 interposed between the bottom of the chamber 5 3 and the bottom of the post 53. The vertical movement of the post 53 is limited by a screw 5'1 the point of which rides in a vertical recess 58 formed in the surface of the post 53.

Assuming that the masks l9 and GI are empty and that the mask I9 is engaged with the stripper plate as shown in Fig. 4, the arms 45 and 46 on the mask 4! are swung outwardly to release it from the mask !9 and permit the mask 4! to be turned back upon its'pivotal connection with the mask I9. The shoe part to be ornamented is then placed in position on the mask IS, the grain or finished face of the shoe part being exposed to view. Then the mask 4| is swung down into engagement with the grain or finished face of the shoe part which is then shifted under the mask 4| to bring some predetermined portion of the shoe part into registry with some predetermined portion on the edge of the opening 42. When the shoe part has been gaged the arms 45 and 45 on the mask 4| are swung inwardly to cause the clips 47 to engage under the mask l9 and thus clamp the masks l9 and 4| together with the gaged work therebetween. Then the operative swings the unitary structure, comprising the clamped masks l9 and 4|, forwardly on a horizontal axis, permitted by the pivotal con nection between the block 49 and the posts 53, into the full line position of Fig. 5. Then the shoe upper part holder, comprising the clamped masks l9 and 4|, is swiveled on an axis, substantially normal to the horizontal axis, permitted by the connection between the pin 59 and the block 49 thus to reverse the relative position of the masks l9 and 4|. Then the reversed masks I9 and 4| are returned to a position where the pins 22, 23, and 24 enter the holes 35, 36, and 31. The gaged work is now positioned with the grain or finished face of the shoe upper part directed towards the cutting edges M of the dies.

Now when the anvil is pushed intothe machine beneath the pressing member thereof and the clutch is tripped, the presser member will come down upon the mask l9 and empale the shoe upper part upon the upstanding edges of the dies,

" the pins 22,23. and 24, the post 53 and the stripper plate l6 being depressed to permit the cutting edges to cut through the work.

When the shoe upper part has been ornamented the anvil is withdrawn from beneath the pressing member of the cut-out machine, the masks l9 and 4| are unclamped, the ornamented shoe upper part is unloaded, and another shoe upper part is located in a gaged position between the masks I9 and 4|. In this next succeeding operation the mask I9 performs the function of a gaging mask. After the masks l9 and 4| have been clamped on the gaged work the position of the masks is again reversed to bring the gaging mask !9 down upon the stripper plate Hi.

It is often highly desirable, in ornamenting shoe upper parts, that a fancy stitch design be correlated both with perforations or other cutouts and impression or imitation stitch marking. In order to prepare a shoe upper part for the fancy stitch marking operation it is necessary to place a guide line on the grain or finished face of the shoe upper part. In impression or imitation stitch marking the marks are placed also upon the grain or finished face of the shoe part. Notwithstanding its desirability, heretofore it has been impossible to correlate a fancy stitch design with impression or imitation stitch marking in any machine in which a mask overlying the marking means was used to gage the work. For the mask must be used to register its positioning means with the fancy stitch guide line at a time when the grain or finished face of the shoe upper part is exposed to the operatives view through the opening in the mask. As the ornamenting means, at the time of gaging, is directed towards the flesh or lining side of the shoe upper part it is apparent that, with the prior art construction and mode of operation, it would be impossible both to gage from a fancy stitch guide line on the grain or finished face of the work and mark that same face with impressions or imitation stitches.

With the illustrated embodiment of the present invention, the stripper plate l6 may be provided with an impression or imitation stitch marker 59 (Fig. 3) in the manner disclosed in the patent to Woodworth, No. 1,733,638, October 29, 1929. In order to locate the shoe upper part properly relatively to the marker 59, the grain or finished face of the shoe upper part may be provided with 10 a guide line 59 (Fig. 1) in the machine disclosed in the patent to Woodworth, Reissue No. 17,715, reissued June 24, 1930. As indicated in Fig. 1 the front edge of the openings 2| and 42 in the masks l9 and 4| may be shaped to register with the guide line 64. After the front edge of the openings 2| or 42 has been registered with the fancy stitch guide line 69 and the gaged work clamped between the masks l9 and 4|, the position of the grain face of the shoe part may be reversed in order to locate it properly to receive the impressions or imitation stitches from the marker 59.

In order to disclose the various features of the present invention in a simple manner the cutout forming means and the work ornamented thereby, have been illustrated and described, respectively, as perforating tubes and the vamp of a made shoe upper. Those skilled in the art will understand that the swiveled work holding and gaging masks may be utilized advantageously in connection with other kinds of dies for forming ornamental cut-outs in various locations and in various kinds of shoe upper parts. For instance, to form cut-outs in quarter blanks it has been necessary heretofore to employ two structures, one having a die, for forming the cut-out in a right quarter blank, and a mask, for gaging the right quarter blank, and the other having a die and a mask for the left quarter blank. By utilizing swiveled work holding and gaging masks a. single structure provided both with a die for the right quarter blank and a die for the left quarter blank may be employed. It will be apparent to those skilled in the art that if the work holding and gaging masks are swiveled on an axis extending centrally between the two dies that the masks will gage a right blank when swung into a position over the right die and will gage a left blank when swung into a position over the left die.

This may be illustrated by referring to Fig. 2. Sometimes the'ornamental cut'outs are formed in the vamp on one side of the center line. In such a case, in order to cause the cutting edges of the die to penetrate initially the finished or grain face of the right and left Vamps, two dies must be employed, one for the right vamp and the other for the left vamp. If the masks are out along the line 6| (Fig. 2) they could be used to gage a right vamp to receive the ornamentations from the tubes marked collectively 62 (Fig. 2) and also could be used to gage a left vamp to receive the ornamentations from the tubes marked collectively 63 (Fig. 2). That is, after the masks had been used to gage a right shoe upper blank for the operation of the right die, the masks could be then opened to unload the ornamented right shoe upper blank, closed to locate the left shoe upper blank and then swung, first upwardly to clear the die, then laterally in the clear, and finally downwardly to locate the gaged left shoe upper blank in position over the left die. Thus, the swiveled masks may constitute a universal gage for both right and left shoe upper blanks.

In fact, the single mask heretofore used with the stripper plate disclosed in the Freeman patent hereinbefore identified, may be converted into a universal gage for both right and left shoe upper blanks by swiveling the mask in the manner disclosed herein. That is, the plate 4| may be disconnected from the plate I9 and the plate l9 cut away along the line 6! (Fig. 2). Then the plate l9, when used with the Freeman strip-- per plate would, like the shoe upper blank gaging means (Fig. 2), constitute a gaging mask constructed and arranged to gage either a right or a left shoe upper blank at the will of the operative.

It will be clear to those skilled in the art and with the general objects of the present invention in view, that other changes may be made in the details of structure and mode of operation, the described and illustrated embodiment thereof being intended as an exploitation of its underlying essentials, the features whereof are definitely stated in their true scope in the claims herewith.
