Application February 1, 1936, Serial No. 61,942 29 claims. (o1. 164-93) 'Ihe present invention relates to devices for ornamenting shoe upper parts. For purposes of disclosure only the various features of the present invention are illustrated and described as being embodied in a device in which the ornamenting means and the work are perforating tubes and quarters, respectively. It will be readily understood by those skilled in the art that the ornamenting means and the work may be any of the other ordinary ornamenting instrumentalities and shoe upper parts, respectively.

In the shoe industry ornamenting devices are used to ornament shoe upper parts in a series of the different sizes and the diiferent widths of the same style. In some instances the parts in the series have a common portion of their peripheries held to the same grade and are called center graded. In other instances the parts in the series have no common portion in their periph- 00 eries and are called regular graded. In still other instances the parts in the series have a portion which is center graded and other portions which are regular graded. To ornament this last mentioned series it is customary to provide the device with a xed group of ornamentng means to ornament each shoe upper part in the series in that portion thereof which is center graded and with a removable group of ornamenting means to ornament one, or in the case of a split grade a few, of the different sizes of shoe upper parts in the portions thereof which are regular graded. It is desirable also to supplement the xed group of ornamenting means with auX- iliary ornamenting means in order to extend the line of ornamentation formed by the xed group from the smallest to the largest shoe upper part in the series. Heretofore the auxiliary ornamenting means has comprised a plurality of sets, the sets being inserted successively in the device singly to augment the line of ornamentation of the xed group as the shoe uppers. operated upon increase in size from the smallest to the largest in the series.

The principal object of the present invention is to produce a device for ornamenting shoe upper parts in which the auxiliary ornamenting means constitutes a permanent part of the device and which may be thrown into and out of operation at the will of the operative.

To the accomplishment of this ob-ject, and such 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 `55 broadly and in detailV in the appended claims.

The various features of the present invention will be understood readily from an inspection of the accompanying drawings illustrating the best form of the invention at present devised, in which, 5r

Fig. 8 is a detail View showing the auxiliary dies in the position they assume upon the elevation` of all the operating keys.

In the illustrated embodiment the work to be operated upon is supported flat-wise upon a stripper plate 9 (Figs. 1 and 2). The stripper plate 9 is supported in the usual manner yieldingly from a unitary structure comprising a top or tube plate 30 Hl and a bottom or tube rest plate II. The top plate I0 and the bottom plate II are clamped together with their adjacent faces in contact. To this end the bottom plate II (Fig. 3) is provided with a plurality of openings I2 each of which re- 35 ceives loosely a post I3 having a slotted head I4 on one end and a cross-pin I 5 on the other.- Coiled about the post I3 and interposed between the bottom plate II and the head I4 is a spring I6. To assemble the top plate Il) and the bot- 40 tom plate I I, the post I3 is turned into the position of Fig. 4. The top plate III is then engaged with the bottom plate II, the cross-pin I5 extending through an opening I'I formed in the top 'plate I0. By pushing the post I3 upwardly and 4 then rotating it from'the position ofFig. 4 to that of Fig. 3 the pin I5 is engaged in a seat I8 formed inthe bottom of a countersink I9 on the top plate IU.

The bottom plate II is provided with lateral 50 lugs 20, (Fig, 5), which are received loosely in ears 2l secured to the opposite sides of a base 22, thus permitting the top plate, the bottom plate and the stripper plate to be swung backwardly to expose the base, (Fig. 5). The pivoted parts 55 are locked to the base in the position of Fig. 1 by a spring pressed pin 23 the point of which is engaged with an opening 24 formed in the front edge of the base 22.

To form the upper at the back of a shoe, two pieces of leather, called quarters, one for the left side and one for the right side, are superimposed, grain face to grain face, and secured b-y a line of through and through stitches inserted along the adjacent back edges of the quarters. The result of this securing of the quarters together is illustrated in Fig. '1 of the patent to Osgood, 1,646,212, October 1'7, 1927.

Referring to Fig. 1, a left quarter is shown at 25 supported atwise upon the stripper plate 9. The wing of the quarter is engaged by aremovable gage 26. The top edge of the quarter is engaged by a xed gage 21. It will be understood by those skilled in the art that the gages 26 and 21 are designed to gage also a right quarter (not shown) supported flatwise upon the stripper plate.

As indicated in Fig. 1, the quarter 25 is ornamented through the use of the illustrated embodiment of the present invention with a series of pin perforations, a small pin perforation 28 alternating with a larger pin perforation 29. In a series of quarters of the same `style varying in size there are certainv portions which are center graded, that is, have a portion `common to each quarter in the series, and certain other portions which are regular graded, that is, have no portion common to each quarter in the series. To ornament such a series of quarters heretofore it has been customary to provide a group Vof tubes or other forms of cutting dies, herein called center graded, which ornament each quarter in the series, and another group of tubes, herein called regular graded, which ornament only one quarter in the series. With such an arrangement the center graded group of tubes are xed while the regular graded group of tubes are interchangeably mounted so that the appropriate group for each quarter in the series may be provided readily.

In the illustrated embodiment of the invention these two groups of tubes are supported with their cutting edges upstanding in the customary manner. That is, the tubes forming the center graded group are received in openings in the top plate Ill, the bottoms of the tubes being engaged with the bottom plate I I. The tubes forming the regular graded group are mounted in a similar manner, but the top and bottom plates therefor constitute an insert 3l) (Fig. 5), which inse-rt may be readily removed and replaced by another insert having a differently arranged group of tubes. To this end the insert 30 is provided with two depending pins 3l the bottom ends of which are received, in the well-known manner, in openings formed in the skeletonized base 22. The top and bottom plates of the insert 30 are preferably removably secured together in a manner identical with that of so securing the plates I and I I.

As usual in this type of device, the stripper plate 9 is provided with a series of openings 32 and 32A through which the cutting edges of the tubes protrude when the presser member of the die press depresses the stripper plate into a predetermined plane in which the work is impaled upon the cutting edges of the tubes.

Referring to Fig. 1, the quarter 25 is a. relatively laige one in a series of the same style. It will be understood that with the smallest quarter in the same series, the last perforation 35 of the center graded group Wouldbe spaced from the back edge of the quarter to clear the line of the back seam. Theoretically, if the center graded group of tubes were extended indefinitely it would seem that the last perforation in each of the re maining quarters in the series would be properly spaced from the edge to clear the back seam line. Practically this desideratum may not be obtained. Actually, if the center graded group of tubes is extended in length to ornament the different sizes of quarters, including the relatively large quarter 25 shown in Fig. 1, throughout the series and is designed to perforate properly the smallest quarter in the series, one of the perforations is bound to come within the area adjacent the back edge reserved for the back seam.

To overcome this difculty, I have limited the extent of the center graded group of tubes to perforate properly the smallest quarter in the series and have provided auxiliary sets of tubes, herein shown for convenience of disclosure as three in number, which are thrown out of operation when the smallest quarters in the series are being perforated, and which are thrown into operation successively when the next three succeeding sizes of quarters in the series are to be perforated.

The first set of auxiliary dies for the left quarter comprise a pair of upstanding tubes 31 (Fig. one for forming a small pin perforation 28 and the other for forming'a larger pin perforation 29, which set is carried by the short arm of a lever 3B. The lever 38 is pivoted on a horizontal pin 39 projecting rearwardly from a block 40 secured to the base 22. The long arm of the lever 38 is provided with an operating key No. 1. The operating key No. 1 is maintained normally elevated by a co'iled spring 4I the opposite ends of which are received in recesses formed in the base 22 and the long arm of the lever 38, respectively.

The rst set of auxiliaryV dies for the right quarter comprise a pair of upstanding tubes 42 (Fig. 5) for forming the pin perforations 28 and 29, respectively, which set is carried by an arm 43 pivoted at one end on a horizontal pin 44 projecting rearwardly from the block 4B. The first sets of auxiliary dies for the left and right quarters are connected to move into and out ,of operating position together by a pin 45 projecting from the free end of the short arm of the lever 38 into engagement with a slot 4G formed in the free end of the arm 43, the adjacent bottoms on the ends of the lever 38 and the arm 43 being slabbed oiT (Fig. 2) to permit their relative movement.

The second sets of auxiliary dies for the next succeeding larger size of left and right guaru ters are duplicates of the first sets of auxiliary dies and are mounted and controlled from operating key No. 2 in a manner identical therewith. The third sets of auxiliary dies are similarly mounted and are controlled from operating key No. 3.

The adjacent ends of the levers 38 and the arms 43 on all three sets of the auxiliary dies are rigidly supported during their perforating operation b-y the upper surface of a bar 41 mounted to slide in a way 48 formed in the base 22. The bar 41on its front end is provided with an operating head 49 and its other end is chambered to receive one end of a spring 50 which is coiled about a rod 5I projecting forwardly from the rear wall of the way 48. The other end of the coiled spring 50 engages a collar 52 on the rod 5I.

lVhen the head 49 is engaged by the operative and the bar 41 is pushed rearwardly, power is stored in the spring 50 and the adjacent ends of Lil the levers 38 and arms 43 of the three sets of auxiliary dies are moved downwardly by the sp-rings 4! into a pocket 53 formed in the bar 41. The bottom 54 of the pocket is a at surface terminating at its opposite ends in vertical walls 55 and 5B, respectively. The position of the parts when the bar 41 is pushed inwardly is illustrated in Fig. 8. As indicated, the bottoms of the levers 38 and the arms 43 engage the surface 54, the bar 41 being held from projection outwardly under the power of the coiled spring 5I) by the back adjacent faces of the levers 38 and the arms 43 on the first set of auxiliary dies which are engaged by the wall 56 on the bar 41. The three sets of auxiliary dies are thus held in a depressed position such that when the presser member of the die press engages the stripper plate 9 and mo-ves it down below the cutting plane of the fixed dies the cutting edges of the three sets of auxiliary dies are not projected through the openings therefor in the stripper plate. Stated in another way, the three sets of auxiliary dies are held out of operation.

When it is desired to perforate the next largest pair of quarters in the series of the same style, the operative depresses operating key No. 1 thereby removing the adjacent ends of the lever 38 and arm 43 of the rst set of auxiliary dies from engagement with the wall 56 of the bar 41, thus permitting the compressed spring 50 to push the bar 41 forwardly until the. wall 56 engages the depressed adjacent ends of the lever 38 and arm 43 of the second set of auxiliary dies. Thus, by depressing operating key No. 1 the operative has elevated the cutting edges of the rst set of auxiliary dies into perforating position and has caused them to be rigidly supported in that position by the upper surface of the bar 41.

Depression of operating key No. 2 serves to elevate the second set of auxiliary dies into the position shown in Fig. 1. Depression of operating key No. 3 elevates the third set of auxiliary dies into perforating position in a similar manner. When the three sets of auxiliary dies have been elevated into perforating position the spring 50 causes the wall 56 to contact a pin 51 projecting into the pocket 53 from the block 40.

To return the auxiliary dies into their inoperative position illustrated in Fig. 8, the operative again pushes rearwardly upon the head 49 until the vertical w'all 56 is re--engaged with the backs of the lever 38 and arm 43 controlled by operating key No. 1. The throwing of the auxiliary perforating tubes into and out of operating position takes place while the upper structure, comprising the stripper plate 9, top plate Il! and bottom plate ll, is locked to the lower structure, comprising the base 22.
