- Pie itknown that I, 'lnoim's Limo, a citi .zcn of the United States, residing at l'iev- ,-e ;ly-, in the county of Essex and State of Massachusetts, have invented certain Impgovements in Devices for Cutting and 'Or- .narnenting Sheet Material,- of which the folwing description,

i referencecharactcrs on the drawings inating like parts in the several figures.

inventionrelatesto dies ,which are for cutting or dying-out pieces of thin eet material such as upper leather for iioot sand shoes and contemplates the provi-- s'lori, means whereby such a die may beefii eiently used for marking, perforating, embossing or otherwisev ornamenting the blanks Libby the die.

jMore particularly the invention relates to the class of dies used with cutting or clicki' .g presses to cutor die out blanks for the various parts of the uppers of boots and shoes and. it is at). objectof the presentinv'ention to provide a die for use with aclick- .ing press whieln beside cutting the outline 0 blank, shall, when desired; form on or. n the blank any desired: perforation or ornamentation. An important advantage of such a deviee is that by its use the operations of cutting and ornament-mg, heretofore sepa ately-perforined, may take place simulta 4 .neously, resulting in greater economy of time and uniformity of product.

It is essential in cutting'blanks from: up-

per leather that dies having a substantially open, unobstructed center should be em-. ployed as-it is important that the operatorshould have an opportunity to inspect criti- 40 daily the blanks about to be cut, in order to locate the die so as to avoid imperfections in theleather. v

' An in'iportant object of the invention. therefore, is to provide a blank ornamenting device which may 'l )e' used in combination with a die" comprising} continuous, open frame having oppositely.disposed cutting and pressure receiving ed :Another object. ofjthe in vention is to proso'vide a die hayinga moperatiiig or supple me'ntary member arranged locut out from ori'mpress into the blank any desired ornamentation, thc construction of such supplein connection with the iinoompanying drawings, a specification,

blank a portion of the useful or ornaln design which it is desired to have appear on nicntary member permitting the. d the ornamentation to be varied r cording to the taste of the shoe'nfl turer. More specifically this inveutio plates theprovision of :1 die with mental) member for the purpose-incom prising a plurality offsectioiis, c ing a device for cutting: or imprc the corresponding; portion "of the finished G5 shoe;;t ogether ivilh means for i'nin'gtbe various sections .when once they in adjusted and arranged to design-v As herein shoxvi r, ming ineans itself. together with punches car- 7()' mod thereby, is capable o ad ustment. with respect to the cutting edge. o

The ornaincntation' forme on tions of the upper of a shoe the nature of a line of pcrt'or j e x ionding in proximity to the edgeotthc'blrmk the configuration and arrangcn-icirt of the perforations being varied to l 'lc'ot shoe of which the blank is it. is V ditlicult to forin cleanly with. the hollbxi monly employed for thisxvork; sine; .t. punehesand the cuttinp bed 'do nottn'ia'ke perfect contact the (:dgesof use it are left ragged. To obviate I. andinsure better contactot pouch and bed it is customaryto insert a sheet of-papcr be tween the stock to be perforated and the cutting bed, a step which objectionable in that it adds to the expense and. complicate' the process. it is, accordingly another ob ject' of my invention to provideablank or i inunenting attaclnnent for a dio by .tbe'iise of which the ornanicniation may be. im-

pressed into, instead of cutout from, the

blank.

()no preferred embodimentof the inven-. tion comprises a combined die-and blanl ornamenting member, said ornameii member comprising interchangeablesec tions, some of the latter forming parts"of: the design and others serving as spacing. blocks' or sections for determining" the proper lo: iion of thelirst. mentioned sections Cooperating with the sect-ions just mentioned and adjustable relative to the ;j

cutting edge of the die, there is provided a retaining bar for said section upon which the latter may be placed as desired and from which they may be removed and others subposes-of; illustration and shown in the acing drawings, in which 1 is 'a perspective view of a'die with" my improved bla'nli'ornadevice, the cutting edge of the die perm'ost, Fi 2 is a perspective View 'ofiagfragment o the die; Fig. 3 is a seer of one of the perforating elements;

' Fig. '43s a perspective iviewof' an embossed blank; Fig. 5 is a section of one of the im- 1 pressing. .or embossing elements.

Fig. '1 illustrates a die for cutting toe tip blanks, and; is provided with a tip perforating device. constructed in accordance with the pife filit, invention. The die 12is of the usual. con-struetion and comprises a continuous or endless frame of strip steel bent to. the required outline and having one edge ground sharpfor cutting and the othercdg flattened to receive the pressure of tl'ie eil, press. On the inside of the rear or straighter blade is adjustably se; cu'red, an undercut bar or web l t upon which are" removably mounted blocks 24;

carrying hollow punches 45 'forperforatingi,

or solid punches 25 for embossin the blank cut by the die! The bar 14 is adjustable to and fromtlie blade ,of the die by meansof screws ,18 and set screws 16, whereby the line of-ornamen-tation may be located nearer or' farther from the edge of the blank according to the space required by thestitrihing. At one end of the bar 14 is a stop 20 and at the other a detachable stop block 30 adapted to be secured to the bar by means ...,of thescrew 31 and provided with screws 22 for clamping the blocks 24-26 together and against the stop20.

The blocks 24 are rabbeted at 37 to correspond with .the bar 14 and slotted at 29. For forming perforations, hollow punches 45 are mounted in the blocks, as shown in Fig. 3, the blocks being perforated at 47 to allow' the punchings to pass up into'the slots 29, which in the assembled device.constitute a continuous channel where the punchings are retained and prevented from falling upon and obscuring the. leather, The location of the bar 14 is such that the upper" surface of each block 24 lies flush with the pressure receiving edge of the die so that the workingpressure is transmitted to each .between two, impressions or secure by of the punches independently of the die, thus relieving the die of any twisting stress when in use.

The punches may be of any desired shape, such as square, oral or circular and their' arrangement on the blocks may be varied to form certain designs, for example, two or more punches may be mounted in a single block, as shown in Fig. 1. i

Besides the pmroll-carrying blocks 24 there are provided spacing blocks 26, rabbeted and slotted like the former, said spacing blocks being for the purpose-of-sepa rating the punch-carrying blocks on the bar 14 when it is desired to incrcase'the distance perforations forming part of the design. a

As alreadystated desirable in some cases to emboss the dcsigii pipstead of forming it of perforations aiidfor such work there are provided bl0 carrying solid punches 25 as shown These; punches may be threaded intothe blocks and furnished with a set nut 27to "p re vent their Working loose; The-length ofst-hgfiOlld punches is less -thaii-=thatof the' xhoilow punches in-order that the design na T Impressed into the blankbut not imea outfrom it.

Fig. 4 illustrates a tip blank 40 cut out by the die 12, the ornamentation 42 on the blank having been formed by solid embossing punches, similar to the punch 25 shown in Fig. 5. The ornamentation, therefore, in this case consists of a series of differently 1.00 shaped depressions formed in the surface ofthe blank. a 1

The blank ornamenting devices hereinbe fore mentioned have been described in .de-. tail and illustrated inconnection with a. tip 10': cutting die but it will be obvious that the invention is in no sense limited to, this particular die but-that, devices embodyingthe invent-ion may be advantageously used with dies for cutting foxings or quarters, or in 1111 short, wherever it IS desirable to employ a. bank ornamenting or perforating device.
