" uatyp'e of` die adapted foruoperations" upon skins, l Wupper blanks, tted orlclosed uppers, and the like, by which markings'rnay be applied to the work, at .fthe saine time, or as part of a cycle of operations,

during which thework -may also be ornamented' f by the perforating or cutting outoyfa design `theregin. `l'referablylithe marking andV perforating or ing will be performedr ina single machine p- 1 ion, andthe marking "may take the form of printing with inkjpr theapplication of a heated lement,or the like.` j

",Butsuoh structures are in manyinstances cum- .bersome, expensive to manufacture,` and in the mental l pattern to accommodate ,large sizes `of` a h `lru'r'iofshoeparts.` 15 l Alprimary object of the present invention is to :provide an.A 'arrangement in which the auxiliary ornamentingelements `constitute a series of permanent parts otthedie structure, any one yor more of which may be thrown into and out of operating Aposition at thewill of the operator.

f *Another object contemplates a simplified `structuremin which the adjustabledieelementsmay be 1moved into or `out of operative position `by the fsiinple flick of a lever.` h The illustrated embodiments `may be con- ,structed similarly to the dies illustratd'inthe patents abovernentioned, with the exception of 'I that portion of the die wherein the ornamenting *elements are arranged for adjustment into and out of their cutting position. y l
