With reference to the drawing, desig-- nates the body of the die which is provided with a conical opening 16 in its front or outer end and a threaded cylindrical opening at 'its opposite or inner end. The die is formed from a plurality of sections 18 here shown as six in number, and each is'of a sector shape having an area one-sixth of the area of the cross-section of the die. The
outer surface 19 "of the die is conical in form to fit the conical surface 16; in the body I 15, while a member 20 is provided in the openin in the body through which pressure is app ied to the sections by means of a threaded membcr2l having, a slot 22 for turning for the application of pressure on the die, thus forcing the sections of the die outwardly and at the same time into close Circumferential relationship by reason of the taper.
The die is hollow as at 23 at one end to provide the negative of the faceted surfaces desired, here shown as six. A surface in a single plane as indicated at 25 is provided on each section 18 and may thus be. highly polished upon any abrasive surface or a glasslate to obtain the polish desired and provi e sharp edges, thus when the six sections, each highly polished are assembled their contacting edges form sharp angles form and is embossed or domed as at 27 by a pair of dies 28 and 29 of a suitable shape. If formed in this shape the hollow die 23 is forced into engagement with the convex surface of this dome, while the same is supported from below by a support die 30 -to impress the shape of the hollow die on this surface which will be highly polished and provided with sharp edges due to the shape .of the hollow die which is impressed thereon,
thus forming a gem or marcasite stone 31.
In some instances the raised portion 32 is provided solid and struck up from the work 33, and in such instances the upper hollow die is forced into engagement with the solid portion which is supported from below by a block 34, having a plain surface 35 there- I find by the use of a tool of this char? acter that small sectionsmay be embossed to form imitation ma-rcasite stones with sharp corners and of a high polish eliminating the necessity of hand touching of the gems, and
yet a gem is provided-which is of great brilliance and a gem of a suprisingly sparkling.
effect is obtained from the faceted surfaces.
The foregoing description is directed solely towards the construction illustrated, but I desire it to be understood that I reserve the privilege of resorting to all the mechanical changes to which the device is susceptible, the'invention being defined and limited only by the terms of the appended claims.
I claim:
1. A tool for forming faceted surfaces comprising a body, a die mounted therein composed of a plurality of sections, each section provided with a surface in a single plane and cooperating with thesurfaces of the other sections to form the negative of the faceted surface desired.
2. A tool for forming'faceted surfaces comprising a body, a die mounted therein composed of a plurality of sections, each section provided with one faceted surface and cooperating with the surfaces of the other sections to form the negative of the faceted surface desired.
3. A tool for forming an impressed design comprising a body, a die mounted therein composed of a plurality of sections,
each section provided with a ortion of the design desired and cooperating with the surfaces of the other sections to form the negative of the complete design desired, and means for maintaining said sections rigidly in position at all times.
4. A tool for forming faceted surfaces comprising a body, a die mounted therein composed of a plurality of sections, each section carrying a surface in a single lane 'and cooperating with the surfaces 0 the other sections to form the ne ative of the faceted surface desired, each 0 said faceted surfaces being highly polished.
5. A tool for making faceted surfaces comprising a body having a conical opening in the front end of the body and a threaded openin forme of aplurality of sections and together fitting said jconical opening, and means including a threaded member engaging said threaded o ening for forcing the die sections outwar ly along said conical surface whereby they tightly contact one with another.
6. A tool for making faceted surfaces comprising a body having a conical openin in the front end of the body and a threade opening at its opposite end, a hollow die formed of a plurality of sections and together fitting said conical opening, and means including a threaded member engaging said threaded opening for forcing the at its opposite end, a hollow die with another, each of said sections being provided with a faceted surface and all of said sections together constituting a faceted hollow die. 7. A tool for making faceted surfaces comprising a body having a conical opening in the front end of the body and a threaded opening at its opposite end, a hollow die formed of a plurality of sections and together fitting said conical opening, and
means including a threaded member engaging said threaded opening for forcing the die sections outwardly along said conical surface whereby they tightly contact one with another, each of said sections being provided with a faceted surface and all of said sections together constitutin a faceted hollow die, and each of said sur aces being highly polished. In testimony whereof I afiix my signature.
